Attention LCD use of LCD

 Come and talk to you today about the use of LCD LCD screen matters needing attention, the following to understand together.

 1. DC voltage shall be prevented:

 The smaller the DC component of the drive voltage, the better. a maximum of not more than 50 mV, of prolonged application of excessive dc composition, electrolysis and electrode aging will occur, thus reducing the lifetime.

 2. UV radiation should be prevented:

 Liquid crystal and polarizer are organic matter, under ultraviolet radiation will occur photochemical reaction, deterioration, so in the uart tft lcd liquid crystal display device assembly should be based on its use and use environment to consider the need to install in front of the ultraviolet filter or other anti-ultraviolet methods. Use should also avoid long periods of direct sunlight.

 3. to prevent harmful gas erosion:

 Liquid crystal and polarizer are organic matter, chemical reaction and deterioration occur in the environment of harmful gas, so the isolation measures of harmful gas should be taken in use, in addition, after the whole machine is assembled, do not carry on long time sealed storage, in case plastic shell and circuit board cleaning agent produce chemical gas concentration too big damage liquid crystal and polarizer.

 4. shall prevent forced extrusion:

LCD made of two pieces of glass, only 5~10 um, thin between them. and the inner surface of the glass is also coated with a layer of directional film, which is easy to destroy. So the LCD screen surface can not add pressure too large, so as not to destroy the directional layer. In case of excessive pressure or hand-held devices during assembly, rest for an hour before electrification. Keep in mind that there must be no drastic temperature change during electrification. The pressure of the device should be uniform, only the side of the presser, can not press the middle, also can not tilt force.

 5. the liquid crystalline state disappears because the segment code LCD exceeds a certain temperature range:

 so must be kept and used within the specified temperature range. The temperature is too high, the liquid crystalline state disappears, becomes liquid, the display surface is black, can not work, please note that at this time must not be electrified, and so on after the temperature is reduced can recover by itself. If the temperature is too low, the liquid crystal begins to form ice flowers, causing permanent damage. Also stored at the limit temperature for a long time or subjected to vibration, shock, LCD will also produce bubbles.

 6. prevent segment code LCD glass rupture:

 Because the display device is made of glass, if lost, the glass will definitely break, so the whole machine design must test the assembly method and assembly vibration and impact resistance.

Forgotten Stone Village: Rarely known by foreign tourists but retaining the memory of a generation in Fujian

For tourists from other provinces of Fujian Province, Fujian tourism is always Xiamen Gulangyu, followed by Zhangzhou Tulou, and finally Nanping Wuyi Mountain. But friends familiar with Fujian know that Fujian’s natural and cultural attractions are very rich, far more than these. However, due to the uneven development of tourism around the region, many of the original ecology, the original taste of the scenery is forgotten, such as in the village of Zhangjiao in Quanzhou.

In fact, in the early days, such narita kagoshima stone houses were not uncommon in the coastal areas of Fujian. Due to the local sea and frequent typhoons in summer, the ordinary wooden house simply cannot adapt to such weather, and the stone house is just in line with the local residents living needs. It can withstand the wind and rain, resist the typhoon this kind of bad weather, but also it can resist the acid corrosion of the sea breeze, warm in winter and cool in summer. Then for a moment, everyone built a stone house.

However, this kind of stone house earthquake resistance is extremely low, with the economic development, but also for safety reasons, many villagers have demolished stone houses, have built new buildings. At the same time, the government has introduced a “stone reform” policy, resulting in fewer and fewer stone houses, so far, such houses have rarely been seen.

Invaluable, in Quanzhou Quangang area also retained this ancient coastal buildings, is mainly represented by Zhangjiao Village. This kind of house is different from the modern people’s construction of reinforced concrete, but is made of stone, even the steps in front of the door are stacked with stone layers.

The roof is made of bricks and tiles, and each tile has a small stone stacked on it to increase the weight of the tiles, thereby better consolidating the roof. It is said that the stone houses of the rich and noble families are all built up flat and flat, while the poorer families are built with different sizes and different shapes of stone.

Although this was only a form of construction which the coastal family had had to do at that time, it was unexpected to look at the stone houses again and again, and to find that their effect was somewhat casual and informal. Perhaps this unexpectedly mischievous design is the beauty that photographers want to capture more than brick houses with rigid rules.

These stone houses are not only a feature nrt to kagoshima of the village to attract visitors to visit, but also a living fossil deeply rooted in the village. The houses bear witness to the vicissitudes of the stone village, where generations of villagers are born and old, carrying the deepest memories in the hearts of generations of old people. Perhaps it is precisely because of this heart of concern, so that these houses continue to show in front of the world, the generations passed on.

Unfortunately, although quanzhou is adjacent to xiamen, the tourism industry has not been its leading industry, although its territory has more natural and cultural tourism resources than xiamen, but did not play its advantages, so that zhangjiao village, such a characteristic tourism village with the nature of network red, only a few people visit.

And such a stone village, across Taiwan’s celery village has been a famous tourist attractions. At present, only a small number of photo-lovers in the province, the group will travel, and for the province’s mass tourists, changjiao village has heard but do not know where its specific, let alone provincial tourists.

Looking for so long, finally found an ideal ancient town, is actually artificial

We have always felt that the cultural city of small towns, historical details that are advertising gimmicks. Many of our ancient tourist towns today are basically rebuilt, just through the historical background, talk about romance, just like the enterprise needs a brand story. So a thousand years old town or a hundred years old city, can really become people yearn for the old town, intuitive feeling is good. Dajueshan ancient town, is let us intuitively feel especially close to the ideal town appearance.

The ancient town of Dajueshan is an ancient town at the foot of the deep mountains in Jiangxi. This is a imitation of the ancient town built in the Song Dynasty, but its overall pattern and the impression is not inferior to those of flights narita to fukuoka the ancient tourist towns, even because there are few visitors to have a more antique charm. But because it is modern imitation, so the use of “ancient” some inappropriate, but it really achieved the “ancient rhyme” feeling.

The ancient town is backed by Dajue Mountain, the mountains are wooded, so the ancient town at the foot of the mountain is often surrounded by green plants. But you don’t have to worry about it, because the low vegetation doesn’t stand in the way, but it gives the ancient town a little bit of natural beauty. Of course, there is a very damaging atmosphere is to walk through the ancient town tour bus, let people play in minutes.

Into the ancient town, stepping on the asphalt slate road, like time through, back to the Song Dynasty. Whether it is the pavilion, or the design of houses on both sides of the street, the Song Dynasty architecture is completely restored in front of tourists. Especially the design of the roof, the Song Dynasty architecture in the roof and the corner of the design features of the ingeniously restored, so that the people into narita to kagoshima the ancient town can more deeply feel the beautiful design of the Song Dynasty architectural roof.

Not only that, you will also see in the roadside with the inscription “official post” stone, see with stone brick high up the gate, even pick up the steps you will accidentally walk into a rich family, enjoy the unique courtyard scenery inside. Such ancient designs would give you the illusion of being in the ancient town of the Song Dynasty.

Xu is to increase the life of some ancient towns, designers used the foot of the gentle flow of small streams, on both sides of the stone stacked to build small buildings, but also specially built in front of the building a asphalt path for visitors to pass. If you are tired of walking, you can also sit on a stone chair on the edge of the path to rest, look at the stone arch bridge not far away, listen to the sound of the slowly flowing stream, but also have a “small bridge and flowing water family” beautiful artistic conception.

Down the stream, there is a small stream of water that is slightly turbulent due to the difference in topography, and these turbulent streams are driving the flow of water underneath it. Go deep again, you will see a group of ancient pavilions built in accordance with the mountains, whenever clouds and fog over the mountain, ancient pavilions, streams, green mountains, like a “human fairyland “.

Because of the limited popularity and no historical background we mentioned before, this imitation of the Song Dynasty town is not known to many people, so strolling among them will not feel because of the number of people lead to destruction anger. And the people who know goods, in addition to a small number of tourists, there are many film and television drama director. Because it is very consistent with the appearance of a small town in the Song Dynasty, attracted a number of crew shooting. And Dajueshan Town was the first film because of the “Tianxian match after the transmission” and invested 180 million yuan to build the film and television city part.

When it comes to ancient towns, we all want to experience the ancient historical relics. However, over time, no matter whether man-made or natural destruction, the true authenticity of the preservation of monuments has been extremely rare. Culture is left in books, truth is left in the original residents, but all this is exhausted by the excessive commercialization of tourism and the mass tourists.

So you’ll find that when we’re sitting in thousands of ancient towns, we can’t find the look of an ancient town that fits our hearts. Historical culture today seems to have become a luxury goods, part of the package after the “fake goods.” So even if the artificial ancient town such as Dajueshan, as long as it is beautiful, taste, charm, so that people can have a visual and psychological enjoyment, then it is the real ancient town. And such ancient towns, we hope more.

Even Hangzhou people envy the West Lake: few foreign tourists disturb, exclusive local residents life fun

With the status and popularity of Hangzhou West Lake in China today, the first thing people think of when it comes to the West Lake is Hangzhou. But in China, the word West Lake is not enjoyed exclusively by Hangzhou. Fuzhou, Yangzhou and Guilin all have large and small West Lake, according to statistics, there are about 36 West Lake parks in China, but some West Lake parks are little known, such as Chaozhou West Lake in Guangdong Province.

Compared with the history, culture and scale of Hangzhou West Lake, Chaozhou West Lake is really difficult to compare with. But the West Lake in Hangzhou is now withered vegetation, rare green, deeply affected by the winter. But flights narita to fukuoka Chaozhou West Lake is still trees, green Ying Ying Ying, not by the cold winter cold attack.

The west lake of chaozhou was formerly known as moat, which acts as a guardian of the ancient city of chaozhou. Therefore, in the beginning, the west lake of chaozhou was called “city moat “. Founded in the Tang Dynasty and famous in the Song Dynasty, the West Lake of Chaozhou was almost destroyed during the war in the Yuan Dynasty.

During the ming dynasty, some landscapes were rebuilt and gradually improved, but in the qing dynasty, because of the rebellion of the minister, he changed from the tourism scene to the establishment of the fort, dig trenches, fences around the fort, to the period of the republic of china, was occupied by warlords, became a famous private garden:” hongyuan “.

Count carefully, Chaozhou West Lake is also a few twists and turns, experienced several destruction reconstruction. This is also Chaozhou West Lake although the long-term history, but the cultural heritage is not very deep root cause. Affected by this, the popularity of Chaozhou West Lake outside is not very high, although it is also one of the famous scenic spots in Chaozhou City, but in addition to a few tourists, only local residents know.

Among the many scenic spots in Chaozhou City, the West Lake is more often positioned as a leisurely park for local residents. Whether it’s before or after meals, or during the day and night, people in Chaozhou are used to going narita to kagoshima to the West Lake for a walk or to relax, or to eat, or to talk and talk.

The total area of the West Lake in Chaozhou is small, and it can be swung around in about half an hour. Usually the elderly and children are more, young people are more rare, only holidays or off-duty time to meet a few more young people. Walking rooms can often see some of the elderly people here to chat, some playing cards, some playing chess, some making tea, and purely with the children sitting and talking about ancient or wandering around, very leisurely.

Although the scenic spots in the lake are few and small, there are a few more well-known local landscapes, such as the legendary “West Lake fishing raft “, the” Huxin Pavilion “, which has been listed by the Chaozhou government as a patriotic education base, the “Furong Pool” with five-color lotus flowers, and the beautiful “Fengqi House “, and so on. Especially in the season of hibiscus pond, five-color lotus open together, really pleasant, let people relaxed and happy.

Chaozhou West Lake is a more leisurely and comfortable place, slow pace, not disease, it as the end of the Chaozhou line to ease the tiredness of the journey for the appropriate. Of course, if it is a business trip to Chaozhou, it is also good to go to the West Lake after work.

Look at Dali in the air: Modern tall buildings are extremely rare, and the edge of Erhai Lake is full of houses

Dali, located in a charming city in the western part of Yunnan Province. This is not like shenzhen, can be seen everywhere high-rise buildings, even in the center of the city,100 meters of tall buildings are extremely rare, is the least high-rise city in china; nor like shanghai, everywhere is a flourishing shopping street. Looking here, is a low-lying residential, distant title Cangshan, near Erhai, integrated, is a leisurely and quiet beautiful scene.

Under the aerial photography Dali, like a sleeping baby, quietly nestled between the Cangshan Erhai, let the heart rise a sense of peace. Overlooking Dali from the air, the winding road on both sides of the road, neatly scattered pieces narita to fukuoka flights of low residential, mostly square rectangle, but there are individual because of the road across the reasons, so that the distribution of housing presents a triangular shape, but let the whole city give birth to a little mischievous interest, is also unexpected surprise.

Dali known as “wind flowers snow moon” city theory, the so-called “wind flowers snow moon “, is” Xiaguan wind, Shangguan flower, Cangshan snow, Erhai moon “four famous wonders. Among them,” Xiaguanfeng “refers to a pass in Xiaguan, whenever the wind season, strong winds through the streets and alleys roaring, tourists in the streets of Xiaguan wind and walk, a sweep of the journey tired, refreshing.

And “close flowers” refers to close an open grassland, because of the mild and humid climate of Dali, very conducive to the growth of flowers and trees, so here flowers, colorful, beautiful. Besides,” Cangshan Snow “is the snow scene of Cangshan all the year round, looking at it, wrapped in silver, dotted with vicissitudes of life.

In particular, every summer season, from a distance, half-mountain green and half-mountain snow, sitting on the cableway up the mountain, like flights from narita to fukuoka from the summer directly into the winter, is also a fascinating sight. Finally, to say “Erhai Moon “, the description is from the air overlooking Erhai, like a crescent moon, quietly lying at the foot of Cangshan.

Erhai Lake has three islands, four continents, five lakes, nine song, the lake clear bottom, known as the world “between the mountains of beautiful jade.” Erhai Lake linked to Cangshan, the moon reflected snow, think are a beautiful painting, no wonder attracted a lot of movies to this horizon sea view, really amazing!

Such a charming city, it is attracted a lot of tourists to come. Therefore, Dali although beautiful, but not idle, throughout the year to receive a lot of tourists from all over the world. Some are college students who come here to start their own graduation trip, some are colleagues and friends who come here in groups to relax, some are free and easy to say walk alone, more loving partners here to end the love run, using the camera to capture their romantic love moment.

Changing with each passing day. For thousands of years, no matter how the outside world changes,” historical and cultural city “Dali has always been its unique charm, attracting a number of tourists to visit here, I believe that the future, with a heavy historical connotation and beautiful scenery of Dali will still be a generation of hearts to the charm of the ancient city!

Under the West Lake Leifeng Tower, the white snake has a mysterious palace, experts give the answer

In 1993,” Legend of the New White Lady,” based on “Legend of the White Snake,” was in the continental fire, and the show, in addition to holding several stars, has since entered the public’s view of the Leifeng Tower in Hangzhou’s West Lake.

The legend of the White Snake has a long history, and the specific age is not to be studied. In the legend, white snake white suzhen in order to save xu xian do not need water diffuse jinshan, many lives have been hurt, because its death is not a few, white suzhen also made an irreparable mistake, violated the sky, in the narita to fukuoka flights birth of the fetus was suppressed by the fahai in leifeng tower. Until Bai Suzhen’s son Xu Shilin grew up, the top high school to worship his mother in front of Lei Feng Tower, Bai Suzhen was released Lei Feng Tower, the family reunion.

The popularity of the hangzhou west lake rose with the popularity of the tv series, especially such as the west lake broken bridge and lei feng tower, which appeared in the tv series, is popular with tourists and the number of visitors has soared. Widely known, coupled with its own good scenery “Leifeng sunset” blessing, so that the Leifeng Tower has become one of the top 10 West Lake attractions, not only that, Leifeng Tower also jumped up, become the coordinates of Hangzhou West Lake.

However, it has been suggested that in the original works, jinshan, jinshan temple is located in zhenjiang city, jiangsu province, the temple’s cishou tower is the real “leifeng tower “, the west lake leifeng tower is not the original suppression of white suzhen tower. In fact, whether it is Zhenjiang City or Hangzhou City, this real “Leifeng Tower” are fictional,” Legend of the White Snake “is a folk story of our country, seriously crooked building. But there is no denying that Hangzhou West Lake Leifeng Tower was a good advertisement for free.

The original intention of Leifeng Tower was that Wu Yue King Qian Chu wanted to use it to pray for peace and security. People worshipped the people at that time and worshiped the ghosts and spirits.

In addition to the back of the story of the White Snake widely spread, the rumors of Leifeng Tower has become even more confusing. Until the beginning of the Republic of China, Leifeng Tower completely collapsed, people found buried under the tower of the palace, from the collapse to the discovery of the palace, reconstruction, which flights from narita to fukuoka took nearly a century, until 2001, the palace began excavation, in 2002, Leifeng Tower reconstruction completed, officially completed.

The rebuilt Leifeng Tower is very modern, and the scenic spots even have escalators and elevators, which are definitely the true meaning of the lazy gospel. After buying the tickets, visitors who don’t want to walk can take the escalator directly above, and then take the elevator to the top floor.

The best time to see Leifeng Tower is when the sun is shining, so if the time can be arranged to go to the top to enjoy the “Leifeng sunset” scenery, after watching it slowly down, look around.

As a cultural landmark of the West Lake and even the whole city of Hangzhou, the Leifeng Tower has a high shot rate, but every city propaganda in Hangzhou must have its place. So the pagoda is also very famous abroad, especially in Southeast Asia. If you ask foreign tourists what are the 10 sights of the West Lake, the highest answer must be the Leifeng Tower.

A Brief Discussion on Commodity Classification of LCD LCD Screen

 For today to introduce LCD next LCD screen classification is how, let’s learn about the following.

 In the practical process, sometimes it is not necessary from the principle. A structure that distinguishes its categories, and more from some aspects of the commodity, the way it is displayed, and the performance of the display, is more practical in application.

 1. commodity forms

 LCD devices: Some LCD devices, including the stone hmi front and rear polarizers, referred to as LCD..

 LCD modules, including assembled circuit boards, IC drive control circuits and other accessories, are referred to as LCM..

 2. display

 Image display: a product that displays deep content on a light background.

 Negative image display: a product that displays light color on a dark background.

 Transmittance display: A product in which the illuminated light source passes through the device to be seen by a positive observer.

 Reflective display: a product in which both the observer and the external light source are on the device side.

 semi-permeable display: the backlight reflective film of this kind of product is equipped with mesh pores, which can be completely illuminated through 30% of the back, so it can be displayed as a reflection type during the day and as a transmission type at night.

How to Use LCD Conductive Rubber Strip for LCD Screen

 Come to talk with you today about the use of LCD LCD conductive tape methods and matters needing attention, below to understand together.

 1. connection requires the use of a structure to LCD the LCD screen with conductive tape and PCB plate fixed together. Conductive rubber strip, conductive silicone strip is the common name of conductive silicone connector.

 2. does not require any welding, thereby eliminating damage to thermal efficient devices. Conductive silicone rubber can be used to connect some heated and vulnerable electronic components instead of welding.

3. can also replace welding at high temperature and radiation, when conductive silicone rubber not only provides a good conductive electrical circuit, but also makes the connection point in a sealed state, play a moisture-proof, anti-corrosion role ;” zero entry force “to prevent the liquid crystal display glass not damage the contact surface;

4. form a layer of airtight seal, so that the printed circuit board in adverse environment without atmospheric corrosion overnight to ensure good connection; buffer and shockproof; easy to adapt to a variety of contact methods; display can be embedded LCD display inserted or removed many times.

5. cutting off a small piece of conductive tape to repair the position of the electric contact like the remote control, for the remote control of the battery electrode place of the iron is relatively easy to be corroded, if a bit of conductive tape on the electrode, one will not rust, two waterproof, three replacement is also convenient, it is a good choice.

 LCD liquid crystal screen conductive adhesive when the use of attention: because the electrode spacing can be done very small, so suitable for driving a number of products, cheap, can help reduce costs; soft and elastic, easy to align, mainly used to LCD the LCD screen and PCB plate signal connection, with good electrical conductivity and stability.

 When we use conductive rubber strips, be sure to wear insulated gloves before operation. Although the conductive tape itself does not conduct electricity, it does not indicate that the object connected by the conductive tape does not conduct electricity.

 Special attention must be paid to ensure that the conductive tape connection of the object completely cut off the power supply after careful operation, or there will be small electric shock, large explosion situation.

LED screen factory tutor you rainy season anti tide

 Do you know LED display screen? Let’s take this down.

Meiyu season, the rain is endless, the air is damp and wet. How can led screens, indoor and outdoor, be dampproof? led the lamp beads in the display screen are sensitive to humidity, the rainy season is destructive to it. How do you solve or prevent moisture or even water from entering a reasonably priced LED screen on rainy days?

Ventilation can speed up the steam evaporation of led display screen with high cost performance. But there is a point worth mentioning, we should avoid ventilation when the air is wet and windless, so that it will only increase the humidity; we can also store a small amount of desiccant indoors to reduce the moisture in the air; when necessary can also turn on the air conditioning wet, the better case is the professional Led screen installed air conditioning, that in wet weather can be directly and easily wet.

But the outdoor price reasonable LED screen is embedded LCD display different, because its own environment is more complex than the indoor, simple can take the indoor method, but can not ignore that the outdoor screen especially in the rainy season to do a good job of waterproof and other daily maintenance work. It is obvious that good sealing can reduce the probability of water intake on the display screen, and regular cleaning of dust on the display screen can make it better heat dissipation and reduce the attachment of water vapor. And so the most important thing is that the most critical waterproof feature of the outdoor branded led display screen is to plan ahead in production.

 Finally led it is very important for the display screen to complement each other in the structure design. It is necessary to choose the suitable contact area and force to make the sealing strip squeeze each other into a more compact state. Also in the position of the waterproof tank need to focus on protection, to ensure that the quality of the led display screen will not contain any water. A few of the above methods can basically ensure that the use of led display during the rainy season will not be damaged by protection problems. All these methods and little knowledge will help you both outdoors and indoors led screen protection.

How to assemble LCD LCD screen correctly?

 Many devices in our lives will use LCD LCD screen, today to specifically analyze how to properly assemble LCD LCD screen, I hope to help you.

LCD the tools assembled by the LCD screen are mainly hammers and wrenches, which are used to screw the frame foot. The order of assembly operation is to put all the tools and raw materials on the workbench in an orderly manner first. Second, the shell according to the process card instructions correctly placed on the worktable, if there is assembly tooling, as required on the tooling, pay attention to the shell direction to be correct. Next remove the protective film of the LCD screen, wipe the electrode with dust-free paper, confirm the direction, according to the process card instructions, correctly put into the shell. remove the circuit board, if you want to add a backlight, the backlight is first fixed on the PCB board. Align the circuit board to the frame position according to the process card. Load the STONE display housing to press the zebra strip and fix the housing and circuit board with special assembly tools. Pay attention to twist the frame foot into 45° angle, do not gnaw the plate and break the line, so that the frame is in parallel contact with the PCB plate. Finally, the finished product will be assembled, removed from the table, affixed protective film, put into the turntable. Pay attention to make the screen and screen opposite, plate and plate opposite, so as not to cause scratches, product assembly finished inspection personnel inspection, unqualified reassembly.

LCD purpose of the LCD screen assembly is to make the screen and the circuit board of each electrode one-to-one correspondence, so that it completes the electrical. But because the screen is not in direct contact with the circuit board, and through the conductive rubber strip as the medium, so that the screen and the plate can not be visually corresponding, so that the respective corresponding electrodes can not correspond to each other, resulting in dislocation phenomenon. In the assembly process, the corresponding electrode connections between the screen and the circuit board are referred to as the opposite position. In the assembly, the corresponding position between the screen and the board is realized mainly by the opposite position between the screen and the board and the shell and the board. shell as intermediate medium, as the corresponding standard between screen and shell, plays a great role in the opposite position. Yes  The bit method mainly includes edge alignment, pinhole alignment and middle alignment.

 Advantages and disadvantages of LCD LCD semi-reverse semi-permeable LCD

 Come to talk with you today about LCD LCD half-reverse half-permeable LCD mode advantages and disadvantages, the following to understand together.

semi-reflective LCD abbreviated TR-LCD, it is a word for transmission and reflection synthesis. TR-LCD structure, because the reflected light passes through the liquid crystal layer twice, the light path of the reflected light is twice different from that of the transmitted light region. TR-LCD disadvantage is that when the surrounding environment light is not too dark, turn on the backlight, and see the image of the transmission region and the reflection region at the same time, which reduces the brightness of the picture quality. In addition, in the reflection region, the light passes through the color film layer twice, and the image of the reflection region and transmission region has color deviation. The process of making reflection zone and transmission zone with different thickness is complicated, and the driving characteristics of transmission zone and reflection zone are different  has brought many difficulties in practical production and application.

 LCD classification can be divided into five main types according to display technology, such as OLED、TFT-LCD、TFD-LCD、SIN-LCD、GF-LCD.

The technology LCD backlight can also be divided into reflective LCD and transmission LCD.. The transmission type LCD display depends on the backlight source and consumes a lot of electricity, but the reflection type LCD does not need the backlight source, it is dependent on the environment light display, the power consumption is low, suitable for mobile phone, PDA and other portable electronic products, so the reflection type LCD has been studied for a long time.

The early antireflective LCD used 90°TN mode, using two polarizers, and later proposed a reflective mixed mode using one polarizer TN、 reflective VA and other modes. a disadvantage of reflective LCD is that the ambient light is reflected on the panel, and the contrast is only 5:1-30:1. Because reflective LCD are mainly used in products such as e-books, it is required to achieve the reflectivity of general paper, that is ,70-90%.
