There is an article in the front of this website 'What is TFT LCD and what is the structure of TFT-LCD?' 》, combined with the TFT-LCD in the product page, we can have a clear understanding of the thin film transistor liquid crystal display (TFT-LCD). Said DID TFT-LCD. What is DID TFT-LCD? DID (Digital Intelligence Display) TFT-LCD is a dedicated LCD screen. It is a new generation of spliced u200bu200bLCD display technology launched by Samsung Electronics in 2006. It is designed and produced in accordance with the technical requirements of professional monitors used in security, radio and television, medical, industrial and public media publishing and other fields. It is a successor to NB, The fourth generation LCD products after PC and TV. With its excellent display performance, it has been recognized as the most high-end and most ideal LCD monitor display. What are the characteristics and advantages of DID TFT-LCD splicing screens? 1. 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'), while the brightness of DID LCD screen can reach 300~500cd/m2 (≤20.1'). 2. High contrast DID splicing LCD screen has a contrast ratio of 1000:1 (≤20.1'), which is more than twice as high as that of traditional PC or TV LCD screens and three times that of general rear projections. 3. Better color saturation At present, the color saturation of ordinary LCD and CRT is only 72%, while the DID LCD liquid crystal screen can reach a high color saturation of 92%, thanks to the color calibration technology developed for DID products. With this technology, in addition to color calibration for still images, it can also be used for color calibration for dynamic images, so as to ensure the accuracy and stability of the image output. 4. Wider viewing angle PVA (Patterned Vertical Alignment) technology is the 'image vertical adjustment technology5. Better reliability. Ordinary LCD screens are designed for TVs and PC monitors, which do not support 24 hours continuous use, while DID LCD screens are designed for monitors and billboards, which support continuous use day and night in public places. 6. Pure flat display LCD is the representative of flat panel display devices, it is a true flat display without distortion. 7. Ultra-thin and narrow-edge design DID products not only have a large display area, but also have the advantages of thin thickness and light weight, which can be easily spliced u200bu200band installed. The 40' LCD screen is spliced, and its excellent narrow-edge design makes the edge of a single piece less than 1.2 cm, so that the edge effect will not affect the overall display of the curtain wall. 8. The brightness is uniform, and the image is stable without flickering. Since each point of the LCD keeps that color and brightness after receiving the signal, it does not need to constantly refresh the bright spot like CRT. Therefore, the LCD has uniform brightness, high image quality, and no flicker. 9. 120HZ double-frequency refresh rate 120Hz double-frequency LCD screentechnology of DID products can effectively solve the smearing and blur in the process of rapid image movement, enhance the sharpness and contrast of the image, make the picture clearer, and the human eye can watch for a long time. Not easy to fatigue. 10. Longer service life The service life of ordinary LCD screens used in NB, PC and TV is 10,000 to 30,000 hours, while the service life of DID LCD splicing LCD screen backlights can reach more than 50,000 hours. This ensures the consistency of brightness, contrast and chromaticity of each LCD screen used in the spliced u200bu200bcurtain wall after long-term use and ensures that the service life of the curtain wall is not less than 50,000 hours. Generally speaking, DID TFT-LCD splicing screen, as a relatively new liquid crystal display, has many of the above advantages, but at the same time, there is also the problem of relatively high prices.
are present in just about every facet of modern life.
