The use of liquid crystals in the liquid crystal under the action of the voltage deflection theory. Since the liquid crystal composition a liquid crystal mosaic screen can be displayed on the same point of red, green, blue color, or a point of the liquid crystal stacking up by three points, which are arranged in a certain order, to stimulate the liquid through the voltage crystal, we can show different colors, you can mix different proportions showing the ever-changing colors. LCD itself is not luminous, it relies on the backlight tubes to light, so depending on the LCD screen backlight tubes. Since the liquid crystal using point imaging reasons, so the screen which constituted more points, imaging finer points aspect constitutes an LCD TV resolution, the higher the resolution, the better.
Currently used to screen LCD splicing wall is mainly DIDTFTLCD more advanced LCD screen. DID (DigitalInfomationDisplay) TFT (Thin-FilmTransistor) LCD (LiquidCrystalDisplay) is a dedicated product LCD screen. It is based on the applied security, radio and television, medical, industrial, and public areas such as media releases technical requirements of demobilized monitor design and production, is the second NB, PC to TV after the fourth generation of LCD products. Its excellent display performance, has become the most recognized high-end, the best LCD monitor display. didTFTLCD LCD screen with high brightness, high contrast, better color saturation, wider viewing angle, better reliability, pure flat panel display, brightness uniformity, image stabilization is not blinking, 120HZ refresh rate multiplier, longer service life characteristics. Specifically has the following outstanding characteristics:
· High brightness
LCD screen with TV and PC compared, DID LCD screen has a higher brightness. LCD TV or PC screen brightness generally only 250 ~ 300cd/m2 (≤ 20.1 ") and 400 ~ 500cd/m2 (≥ 26"), and DID LCD screen brightness can reach 300 ~ 500cd/m2 (≤ 20.1 ") and 700 ~ 800cd/m2 (≥ 26 ").
· High Contrast
DID LCD screen with 1000:1 (<= 20.1 ") 1500:1 (≥ 26") contrast than traditional LCD PC or TV to more than double the normal projection of three.
· Better color saturation
Currently normal LCD and CRT color saturation is only 72%, while DIDLCD can reach 92% of high color saturation, thanks to a newly developed DID color calibration technology, through this technology, in addition to still images for color calibration, but also on the dynamic screen color calibration, so as to ensure accurate and stable image output.
· A wider viewing angle
PVA (PatternedVerticalAlignment) technology that is "vertical image adjustment technology", the use of this technology, 170 ° viewing angle of up to more than double (horizontal and vertical).
· Better reliability
Ordinary LCD TVs, PC monitors design, does not support the night of continuous use; DID LCD screen as a monitor, billboards designed to support continuous use day and night in public places.
· Pure Flat Panel Displays
LCD flat panel display equipment, is truly flat screen monitors, no curvature at the big picture, no distortion.
· Uniform brightness, image stabilization is not blinking
Since the LCD each point in the received signal has maintained that the color and brightness, unlike the CRT as the need to constantly refresh the highlights. Therefore, LCD brightness uniformity, high quality and never blink.
· 120HZ refresh rate multiplier
Patented 120Hz frequency LCD technology, can effectively solve the image smearing during fast motion and blur, enhanced image clarity and contrast to make the picture more clear, the human eye fatigue watch a long time.
· Longer life
Ordinary NB, PC and TV use its LCD screen backlight life is 10000-30000 hours, while DIDLCD LCD backlight life can be up to 50,000 hours or more, which ensures the use of mosaic wall Each piece LCD screen after prolonged use of the brightness, contrast and color consistency and to ensure that the curtain wall is not less than 50,000 hours service life.
· Slim narrow design
Ultra Narrow DID LCD splicing screen has a large display area at the same time, there are thin, light weight advantages, easy to splice and installation. Generally 40 inches DIDLCD, its weight is only 12.5KG, thickness of less than 10 cm, splicing dedicated LCD splicing screen walls, narrow its excellent design, so that the edge is only a centimeter, as opposed to 40-inch big screen, the such a small edge do not affect the overall display wall.
