Wide application of DID LCD splicing screen technology
1. What is DID?
DID is short for Digital InformaTIon Display. It is a new generation of liquid crystal display technology launched by Samsung Electronics in 2006. It is widely used in security monitoring in various industries (hydropower production scheduling, military command, city management, mining safety, environmental monitoring, fire meteorology and maritime command systems, etc.), ( Information releases such as government corporate video conferences, financial securities, airport subway mall hotel communication information, etc. (in theaters, stadiums, fairs, concerts, party media advertisements, etc.) display systems, and commercial display rentals in LCDs. As its unique display technology, it is different from ordinary liquid crystal displays in that it improves the arrangement structure of liquid crystal molecules and can be placed horizontally and vertically. High brightness, high definition (1080P), super long life, stable operation, low maintenance cost. DID LCD screen provides customers with an ultra-high resolution, ultra-large display area LCD screen with single screen high resolution (1366X768, 1920 X1080) and full screen (1366xMx768xN, 1920xMx1080xN). At present, the main sizes of Samsung DID LCD screens are 32 â€, 40â€, 46 â€, 52â€, 57 â€, 70â€, 82 â€,
Second, DID LCD screen features:1. High brightness
Compared with TV and PC LCD screens, DID LCD screens have higher brightness. The brightness of the TV or PC LCD screen is generally only 250 ~ 300cd / m2, while the brightness of the DID LCD screen can reach more than 700 cd / m2.
2. High contrast
The DID LCD screen has a contrast ratio of 1200: 1 or even 10000: 1, which is more than double that of traditional PC or TV LCD screens and three times that of general rear projection.
3. Better color saturation
At present, the color saturation of ordinary CRT is only about 50%, and DID LCD can achieve high color saturation of 80% -92%. This is thanks to the color calibration technology developed for DID products. Through this technology, in addition to the still picture In addition to color calibration, color calibration can also be performed on dynamic pictures, so as to ensure the accuracy and stability of the picture output.
4. Wider angle of view
PVA (Patterned VerTIcal Alignment) technology is the "vertical image adjustment technology", using this technology, the viewing angle can reach dual 180 ° (horizontal and vertical).
5. Better reliability
Ordinary LCD screens are designed for TVs and PC monitors, and do not support continuous use day and night. DID LCD screens are designed for monitoring centers and display centers and support continuous use for 7x24 hours.
6. Pure flat display
The LCD is a representative of flat panel display devices, and is a true flat-screen display with a large picture without curvature and no distortion.
7. Ultra-thin narrow side design
DID products have the advantages of large display area, thin thickness and light weight, which can be easily spliced ​​and installed. The splicing dedicated LCD screen, with its excellent narrow-edge design, makes the edge of the single piece even below 1 cm, so that the small edge effect will not affect the overall display effect of the entire display.
8. Uniform brightness, stable image without flicker
Since every dot of the LCD keeps the color and brightness after receiving the signal, unlike the CRT, it needs to constantly refresh the pixel dots. Therefore, the LCD has uniform brightness, high picture quality and absolutely no flicker.
9, 120HZ double frequency refresh rate
The 120Hz frequency doubling liquid crystal display technology of DID products can effectively solve the smearing and blurring during the rapid movement of the image, enhance the clarity and contrast of the image, make the picture clearer, and the human eye is not prone to fatigue after long time viewing.
10. Longer service life
The service life of the backlight of ordinary LCD screens used by NB, PC and TV is 10,000 to 30,000 hours, while the service life of the backlight of DID LCD screens can reach more than 50,000-100,000 hours, which ensures The consistency of the brightness, contrast and chromaticity of each LCD screen used in the spliced ​​display after long-term use, and to ensure that the service life of the display is not less than 50,000 hours.
3. Composition of DID liquid crystal display systemThe DID liquid crystal display system is composed of three major parts, namely a splicing display wall, a multi-screen splicing processor and a signal source. Among them, the multi-screen splicing processor is the core of the key technology, which supports the display of images of different pixels on the large-screen display wall and any window open, zoom in and out, and cross-screen roaming display on the large-screen display wall.
4. Application of DID LCD splicing display systemThe large-screen splicing picture is magnificent and the visual impact is strong. It has a good effect of display, demonstration, advertisement and publicity. And it is easy to install, not limited by space, and its application fields are widely used in: power production dispatch control center, military command and control center, city management emergency command center, traffic management command center, industrial process control display system, radio and television display and monitoring system, Shopping malls, hotels, communication information display systems, financial securities information display systems, government enterprise multimedia video conference display systems, mining safety production monitoring systems, urban environment monitoring and command systems, fire, weather, maritime flood control command systems, airport, subway flight display, Baggage, security monitoring system, theater, media advertisement, exhibition display system, brand specialty store image display system, concert, display equipment rental ...
The LED Underwater Light is a light that is placed under the water. The appearance is small and exquisite, and the appearance is elegant. As an Underwater Lighting fixture, LED underwater light is widely used in various sightseeing places such as square parks. It is the perfect choice for fountains, theme parks, exhibitions, commercial and art lighting.Most of the materials are made of stainless steel and glass. The types of stainless steel are 201, 304, 316, etc.This Lamp is designed with fully tempered safety glass, wide light radiation surface, strong transparency.The interior of the luminaire is highly waterproof and has a protection rating of IP68 or higher .All adopt imported high-power LED as light source, which has obvious advantages such as long life, low power consumption, pure color and no pollution. With the DMX512 control system, it can achieve a variety of color changes.If you want to know more, please contact us.
