DID is the abbreviation of Digital Information Display. It is a new generation of liquid crystal display technology introduced by Samsung Electronics in 2006. It is widely used in LCD monitors in various fields such as security monitoring, information distribution, display systems, and commercial rental of display devices. . The liquid crystal display using the DID technology is different from the ordinary liquid crystal display in that the arrangement structure of the liquid crystal molecules is improved, and it can be placed horizontally and vertically in a ceiling.
The DID LCD display is based on DID as the splicing technology. DID LCD screen provides high resolution and large display area LCD screens for customers with single-screen high resolution (1366X768, 1920X1080) and full screen (1366xMx768xN, 1920xMx1080xN).
DID LCD display features
1, high brightness
Compared with TV and PC LCD screens, DID LCD screens have higher brightness. TV or PC LCD screen brightness is generally only 250 ~ 300cd/m2, and DID LCD screen brightness can reach 700cd/m2 or more.
2, high contrast
DID LCD screens have a contrast ratio of 1200:1 and even 10,000:1, which is more than twice as high as traditional PC or TV LCD screens, and is three times that of ordinary rear projection cameras.
3, better color saturation
At present, the color saturation of ordinary CRT is only about 50%, and DIDLCD can achieve high color saturation of 80%-92%, thanks to the color calibration technology developed professionally for DID products. Through this technology, in addition to the still picture In addition to color calibration, it is also possible to calibrate the color of dynamic pictures so as to ensure the accuracy and stability of the picture output.
4, a wider perspective
The PVA (Patterned Vertical Alignment) technology is an "image vertical adjustment technique". With this technique, the viewing angle can be double 180° (horizontal and vertical).
5, better reliability
Ordinary LCD screen is TV, PC monitor design, does not support continuous use day and night, DID LCD screen for the monitoring center, display center design, support for continuous use in 7x24 hours.
6, pure flat display
The LCD is a representative of a flat panel display device. It is a true flat-screen display with no large curvature and no distortion. Ultra-thin and narrow-edge design DID products have the advantages of thin thickness, light weight, etc., while they have a large display area, and can be easily spliced ​​and installed. Splicing dedicated LCD screen, its excellent narrow-edge design, so that the monolithic edge is even less than 1 cm, such a small edge effect will not affect the overall display of the overall display.
7, uniform brightness, image stability does not flicker
Since each point of the LCD maintains that color and brightness after receiving the signal, unlike the CRT, it needs to constantly refresh the pixels. Therefore, the LCD has uniform brightness, high image quality, and absolutely no flicker. 120Hz double frequency refresh frequency 120Hz double frequency liquid crystal display technology of DID products can effectively solve the smearing and blurring in the fast motion of the image, enhance the sharpness and contrast of the image, make the picture clearer, and the human eye can watch for a long time without fatigue. .
8, longer service life
The LCD backlights used by ordinary NBs, PCs, and TVs have 10,000 to 30,000 hours of backlight life, while the backlight lifetime of DID LCD screens can reach 5-10 million hours or longer. This ensures the splicing. The brightness, contrast and chromaticity of each LCD panel used in the display after a long period of use are consistent, and the life of the display is not less than 50,000 hours.
9, environmental health
DID LCD splicing display has small heat, no radiation, no flicker, no eye damage, no harmful substances (such as lead, mercury, etc.), and is a splicing curtain for environmental protection and health. In some developed countries in Europe and America, LCD splicing curtain wall has replaced traditional Rear-projection splicing curtain walls have become mainstream.
10, arranging arbitrary choice, convenient and flexible
DID LCD splicing display screen, in addition to the number of arbitrarily selected, the combination of the screen (m Х n) also has a variety of options to meet the needs of different places of use. Recommended size 40"/46"/52" and other splicing display combinations are optional, can be personalized according to the user's different needs, you can choose single-screen display, full-screen display, any combination of display. Can achieve screen stretching, Zoom, roaming, overlay, and more.
Wire thread inserts are helically coiled fastening devices that provide permanent, wear-resistant screw threads that exceed the strength of most parent material; the inserts are designed to protect tapped holes against failures due to stripping, seizing, corrosion, and wear.
Threaded inserts are typically used when the object in which a threaded fastener is being installed is made of a soft material. For hard materials, a screw or bolt can be often driven into the object without the need for a threaded insert. A simple solution is to use a threaded insert.
