LED display since its inception has received widespread attention, with the continuous progress of LED display technology in recent years, has been recognized by various industry sectors.
The production and maintenance of LED displays also requires specialized knowledge.
To achieve high-definition display there must be four factors: first, the video/picture source requires high-definition; second, the monitor is required to be able to support full high-definition; third, to reduce the dot pitch of the LED display; and fourth, the LED display is combined with a video processor.Currently, LED displays are also moving towards higher definition displays.
- Improve the contrast of the LED display is one of the key factors affecting the visual effect, generally speaking, the higher the contrast, the clearer and more eye-catching image, the more vivid and colorful.
High contrast for image clarity, detail performance, gray level performance are very helpful. In some black and white contrast text, video display, high contrast full color LED display in black and white contrast, clarity, completeness and other aspects have advantages. Contrast for dynamic video display effect to have a greater impact, due to the dynamic image of light and dark conversion is relatively fast, the higher the contrast, the easier it is for the human eye to distinguish such a conversion process. In fact, the contrast of the LED full-color screen to improve the brightness of the full-color LED display as well as reduce the surface reflectivity of the screen, but the brightness is not the higher the better, too high, on the contrary, it will be counterproductive, not only affects the life of the LED display, but also cause light pollution. Light pollution has become a hot topic now, too high brightness will have an impact on the environment and the crowd. Full-color LED display LED panel and LED light-emitting tube for special process, can reduce the reflectivity of the LED panel, can also improve the contrast of the full-color LED display.
- Brightness interval level
The higher the grayscale level of the LED display, the richer the color, the more colorful; on the contrary, the display color is single, simple changes. Gray scale level increase, can greatly enhance the color depth, make the image color display level is geometric quantity increase.
LED grayscale control level of 14bit ~ 16bit, so that the image level of high-end display products to resolve the details and display effects have reached the world's advanced level. With the development of hardware technology, LED grayscale level will continue to higher control precision development.
- Reduce the LED full-color display screen point spacing
Reduce the point spacing of LED full-color display, can be very good to improve its clarity, the smaller the point spacing of full-color LED display, the more delicate its picture display. However, this point, there must be mature technology as the core support, its input cost is relatively large, the full-color LED display produced by the price is also high, but fortunately now the market is also moving towards small pitch LED display development.
- LED display combined with video processor
LED video processor can use advanced algorithms to image poor quality signal modification, the implementation of de-interlacing, edge sharpening, motion compensation and so on a series of processing, enhance the details of the image, improve the quality of the screen. The use of video processor image scaling processing algorithms to ensure that the video image after scaling, the maximum degree of clarity and gray level of the image to maintain. In addition, the video processor is also required to have a wealth of image adjustment options and adjustment effects on the image brightness, contrast, grayscale processing to ensure that the screen output soft and clear picture.
