First, improve the contrast of the LED screen
Contrast is one of the key factors affecting the visual effect, generally speaking, the higher the contrast, the clearer and more realistic images, the more vivid colors. High contrast for image clarity, detail performance, gray level performance are very helpful.
Second, improve the LED screen gray level
LED large screen gray level refers to the single color brightness from the darkest to the brightest, can distinguish between the number of brightness levels, LED large screen gray level is higher, the richer the color, the more colorful; on the contrary, show a single color, simple changes. Gray level of improvement, can greatly enhance the color depth, making the image color display level geometric increase. Now many LED screen manufacturers can display the grayscale level to 14bit ~ 16bit, so that the image level resolution details and display more detailed and realistic, colorful.
Third, reduce the LED screen point spacing
Reduce the LED screen point spacing, can be very good to improve the clarity of the display screen, because the smaller the point spacing, LED screen pixel density per unit area is higher, more details can be displayed, the more detailed the screen display is more detailed and realistic.
Fourth, the LED screen combined with the video processor
LED video processor can use advanced algorithms for poor image quality signal modification, the implementation of de-interlacing, edge sharpening, motion compensation and a series of processing, enhance the image display details, improve the quality of the screen display. The use of video processor image scaling algorithms to ensure that the video image after scaling, the maximum degree of clarity and gray level of the image; in addition, it is also necessary to video processor has a wealth of image adjusting options and adjusting the effect of the image brightness, contrast, grayscale processing to ensure that the LED screen output soft and clear picture.
