A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden, such as preset words, digits, and seven-segment displays, as in a digital clock. They use the same basic technology, except that arbitrary images are made up of a large number of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the color of the backlight, and a character negative LCD will have a black background with the letters being of the same color as the backlight. Optical filters are added to white on blue LCDs to give them their characteristic appearance.

LCDs are used in a wide range of applications, including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage. Small LCD screens are common in portable consumer devices such as digital cameras, watches, calculators, and mobile telephones, including smartphones. LCD screens are also used on consumer electronics products such as DVD players, video game devices and clocks. LCD screens have replaced heavy, bulky cathode ray tube (CRT) displays in nearly all applications. LCD screens are available in a wider range of screen sizes than CRT and plasma displays, with LCD screens available in sizes ranging from tiny digital watches to very large television receivers. LCDs are slowly being replaced by OLEDs, which can be easily made into different shapes, and have a lower response time, wider color gamut, virtually infinite color contrast and viewing angles, lower weight for a given display size and a slimmer profile (because OLEDs use a single glass or plastic panel whereas LCDs use two glass panels; the thickness of the panels increases with size but the increase is more noticeable on LCDs) and potentially lower power consumption (as the display is only "on" where needed and there is no backlight). OLEDs, however, are more expensive for a given display size due to the very expensive electroluminescent materials or phosphors that they use. Also due to the use of phosphors, OLEDs suffer from screen burn-in and there is currently no way to recycle OLED displays, whereas LCD panels can be recycled, although the technology required to recycle LCDs is not yet widespread. Attempts to increase the lifespan of LCDs are quantum dot displays, which offer similar performance as an OLED display, but the Quantum dot sheet that gives these displays their characteristics can not yet be recycled.

Since LCD screens do not use phosphors, they rarely suffer image burn-in when a static image is displayed on a screen for a long time, e.g., the table frame for an airline flight schedule on an indoor sign. LCDs are, however, susceptible to image persistence. The LCD screen is more energy-efficient and can be disposed of more safely than a CRT can. Its low electrical power consumption enables it to be used in battery-powered electronic equipment more efficiently than CRTs can be. By 2008, annual sales of televisions with LCD screens exceeded sales of CRT units worldwide, and the CRT became obsolete for most purposes.

NDSsi uses only “Grade A” LCD panels in all of its products, while many competitors use “Grade B” panels in order to save cost, and as a result compromise quality. In medical applications, it is important not to compromise the quality of the displayed image since it is often the basis for making clinical decisions. The following tables and images show the differences between “Grade A” and “Grade B” LCD panels in terms of different types of allowable defects.

There are essentially two different types of pixel defects, bright (stuck pixels) and dark (dead pixels).The table and images below show the differences between Grade A and Grade B LCD panels in terms of allowable pixel defects.

There are thousands of repair shops and cell phone parts wholesalers in the world providing broken screen replacement service. Most of the cellphones which need to be repaired are iPhone and Samsung. There is a question - what is the quality grade of iPhone lcd screens that the repair shops used to replace the broken screen ? Please read below information to get answers. According to our investigation, we found 90% Chinese iPhone LCD Screen suppliers selling third-party manufactured screens. They seldom sell genuine original lcd screens. And there is an interesting phenomenon that most of the repair shops and aboard wholesalers buy third-party produced lcd screens, why? maybe the price is cheaper. So, if your screen is broken, you may get a high chance of being replaced with a non-original screen. How many quality grades of iPhone LCD Screen? Some technicians in repair shops can not distinguish original and high copy iPhone LCD Screen, they sometimes are cheated by their suppliers. Here we explain the quality grade of iPhone LCD screens.

1.Third-Party Manufactured (All the raw material are copy) With the shortage of original screen, Chinese factories begin to produce high copy lcd screen now. From Aug, 2015,the cellphone parts industry is suffering from a big headache - that is theoriginal iPhone lcd screen is almost out of stock. The stock is getting less and less. The price is growing day by day. Some companies sales volume is dropped crazily and they are closed. To solve the problem, Chinese factories begin to produce lcd screens. Of course, all the raw material is high copy. There are 4 factories manufacturing the screens. The 4 factories are TM,BOE,LT and JDF. We had tested the screens from the 4 factories, we find that TM is the best. The display color and resolution is the best. And the appearance looks the same as original.

2.Third-Party Assembled (display is original, other material are copy) Some Chinese factories buy the original lcd display from Original factory, but what they buy is not a complete lcd screen, they just buy a raw material - single display. They produce high copy front glass, lcd display flex cable and backlight. Then, they attach these materials to a complete lcd screen. After attaching lcd, lcd flex cable and glass, they need remove the bubble in the display with a bubble machine. Such kind lcd screen is showing normal image and working too, but quality is not stable and the display color is slightly different since the factory use high copy backlight. Of course, the price is cheap, many repair shops and wholesalers love it.

3.Refurbished. If your iPhone Front Screen is broken(lcd is still working, just glass is broken), it can be recycled to reuse. Some factories specially recycle these kind broken screens, they just need remove the broken glass, and attach a new glass, the lcd screen will be new again.This is called refurbished, the quality is much more stable than the Third-Party Manufactured. Of course, brand new original lcd screen is limited,the refurbished screens can replenish the shortage of the new original lcdscreens.

4. Brand New Original. Apple authorized Foxconn to assemble iPhone. There are some original iPhone LCD Screens leaked from Foxconn. And to meet the repair demand, there are some original screens brought out from original factory. But, the truth is that the price is high. Some people may not accept the high expense to repair his phone. While some people more care about quality, so they prefer Original Quality.

To meet different buyer"s demands, we have both the 4 different quality grade of iPhone LCD Screens. All these lcd screens are Grade AAA Quality since we test each one strictly at least two times. If you wholesale iPhone LCD Screenor repair iPhone screen as a job, you can contact us to get more information and better prices.

An LCD video wall is a large visualization surface that is built from multiple LCD displays (also known as ‘tiles’). These individual displays are designed specifically for use in these applications, and differ highly from normal television sets. The biggest differences are the bezel width, the mounting system, and the reliability. Normal television sets are designed to play a few hours per day, these specific panels are expected to play much more. Often even 24/7. And because the environments in which these video walls are deployed are sometimes critical, the uptime needs to be as high as possible.

Especially important for video walls, is a perfect calibration. This is not only restricted to a single panel. More critical, is that the color and brightness settings of the complete wall match. This means that the values of all panels need to be synchronized with the surrounding displays. If not, even the slightest deviation in color or brightness will make the wall seem out of balance.

High brightness: The light output of LCD video walls is generally quite high. Especially compared to LED-lit rear-projection cubes, LCD scores better. This allows the use in most lighting conditions - even in daylight.

Low real estate needs: Rear-projection cubes are quite deep, and (unless front access is available) need a rear maintenance area. As such, they need a lot of real estate space. LCD video walls only take the place on the wall of the panel depth and the wall mounting. This is usually less than 20 cm / 7.9”.
