Emperor Aidi analyzes the principle of work and construction of LCD Video Wall

Liquid crystals are based on the principle of using liquid crystals to deflect under the influence of voltage. Since the liquid crystals composing the liquid crystal splicing screen can display the three primary colors of red, green and blue at the same point, or that one point of the liquid crystal is superimposed by three points, they are arranged in a certain order and the voltage is used to stimulate the liquids. Crystals can present different colors, and different proportions can present ever-changing colors. The liquid crystal itself does not emit light, and it shines back to the light pipe, so the LCD screen of Di Edi depends on the backlight tube. Because the LCD uses point imaging, the more dots in the screen, the finer the imaging effect. The vertical and horizontal dots constitute the resolution of the LCD TV. The higher the resolution, the better the effect.

The current advanced screen for LCD splicing walls is mainly DIDTFT LCD. The DID (Digital Infomation Display) TFT (Thin-Film Transistor) LCD (Liquid Crystal Display) is a dedicated product LCD screen. It is designed and produced according to the technical requirements for security monitoring, broadcasting, television, medical, industrial and public media distribution and other fields. It is the fourth generation of LCD products following NB and PC to TV. Its outstanding display performance has become the most high-end and most ideal LCD monitor display that people recognize. didTFTLCD LCD screen with high brightness, high contrast, better color saturation, wider viewing angle, better reliability, pure flat display, uniform brightness, image stabilization without flicker, 120Hz frequency update frequency, longer service life, etc. feature. Specifically has the following salient features:

High brightness Compared with TV and PC LCD screens, DID LCD screens have higher brightness. The brightness of TV or PC LCD screen is generally only 250~300cd/m2(≤20.1”) and 400~500cd/m2(≥26”), while the brightness of DID LCD screen can reach 300~500cd/m2(≤20.1”) and 700~800cd/m2(≥26”).

High-contrast DID LCD screens have a 1000:1 (<=20.1”) 1500:1 (≥26”) contrast ratio, which is more than double that of conventional PC or TV LCD screens, and is three times that of a typical rear-projection camera.

Better Color Saturation At present, the color saturation of ordinary LCD and CRT is only 72%, and DIDLCD can achieve high color saturation of 92%, thanks to DID's newly developed color calibration technology. Through this technology, in addition to In addition to color calibration for still images, color calibration can also be performed on dynamic images to ensure accurate and stable image output.

• The wider viewing angle PVA (Patterned Vertical Vertical) (PVA) technology is the “image vertical adjustment technology”. With this technology, the viewing angle can be more than double 170° (horizontal and vertical).

Better reliability The common LCD screen is designed for TVs and PC monitors, and does not support continuous use day and night; DID LCD screens are designed for monitors and billboards, supporting continuous use day and night in public places.

· The pure flat display LCD is a representative of the flat panel display device. It is a true flat-panel display with no large curvature and no distortion.

Uniform brightness, image stability and no flicker Since each point of the LCD maintains that color and brightness after receiving the signal, it does not need to constantly refresh the bright spots like the CRT. Therefore, the LCD has uniform brightness, high image quality, and absolutely no flicker.

120Hz frequency doubling refresh frequency The patented 120Hz frequency doubler liquid crystal display technology can effectively solve the smearing and blurring of the fast motion of the image, enhance the sharpness and contrast of the image, make the picture more clear, and the human eye can easily watch fatigue for a long time. .

· Longer lifespan The LCD screens used by ordinary NBs, PCs, and TVs have a 10,000 to 30,000 hours of backlight life, and the life of DID LCD backlights can reach 50,000 hours or more. It ensures the consistency of brightness, contrast, and chromaticity of each LCD panel used in the splicing curtain after a long time use and ensures that the service life of the curtain wall is not less than 50,000 hours.

· Ultra-thin and narrow edge design Ultra-narrow edge Aidi electronic LCD splicing screen has a large display area at the same time, there are thin, light weight and other advantages, you can easily splicing, installation. The 40-inch DID LCD has a weight of only 12.5KG and a thickness of less than 10cm. The splicing-dedicated liquid crystal splicing screen wall has an excellent narrow-edge design with an edge of only 1cm. Compared with the 40-inch screen, Such a small edge does not affect the overall display of the curtain wall.
