Four factors are required to realize the HD display: first, full HD, second, support the display requirements of full HD, and third, reduce the point spacing of the combination of LED electronic screen and video processor. Fourth, use video processor.
First, improve the contrast of full-color LED display
Contrast is one of the key factors affecting visual effects. Generally, the higher the contrast, the clearer the image, and the brighter the color. High contrast is very helpful for image clarity, detail performance and grayscale performance. Some high contrast full-color LED displays on text and video displays with large black and white contrast have the advantages of black and white contrast, clarity and integrity. Contrast has greater influence on dynamic video display. Because in dynamic images, the light dark conversion is fast and the contrast is high, it is easier for the human eye to distinguish this conversion process.
The contrast improvement of the true color LED electronic screen mainly focuses on improving the brightness of the full color LED electronic screen and reducing the reflectivity of the screen surface. However, the higher the brightness, the better. If the brightness is too high, it will have a negative effect, which will not only affect the life of the LED electronic screen, but also affect light pollution. Light pollution has become a hot topic. Too high brightness may affect the environment and population. Full color LED panel and LED light emitting tube are used to reduce the reflectivity of LED panel and improve the contrast of true color LED display.
Second, improve the gray level of full-color LED electronic screen
Gray scale refers to a series of brightness from a single basic color brightness of full-color LED electronic screen to the darkest to brightest color. The higher the gray scale of full-color LED electronic screen, the richer the color, and the richer the color. On the contrary, the display color is single and the deformation is simple. Increasing the gray level can significantly increase the color depth, thereby increasing the display level of image colors exponentially. The LED grayscale control level is from 14 bits to 16 bits, improving the image level resolution details and display performance of high-end display products to the world's highest level. With the development of hardware technology, LED gray level continues to develop to higher control accuracy.
Third, reduce the dot spacing of full-color LED display
Reducing the dot spacing on the true color LED electronic screen can improve the definition, while the smaller the dot spacing on the true color LED electronic screen, the more delicate the screen will be displayed. However, we must have the technology that has been proved to be the core support. The investment is relatively high, and the price of the full color LED display manufactured is also high. But the market has now developed to small pitch LED display.
Fourth, use video processor
LED video processors use advanced algorithms to correct signals with poor image quality, and perform various processes, such as interlaced deletion, edge sharpening, motion compensation, etc., to improve image detail and quality. The video processor image scaling algorithm is used to maximize the sharpness and grayscale of the video image.
