since its birth, led display has received extensive attention. with the continuous progress of installation technology in recent years, it has been recognized and applied in various industries. the production and maintenance of led video display screen also need professional knowledge. so how to realize high-definition display of led display? in fact, there must be four factors to achieve high-definition display. here is what four elements are for you to analyze.
first, to improve the contrast of full-color led display screen, contrast is one of the key factors affecting the visual effect. generally speaking, the higher the contrast, the clearer the image is, the brighter the color is. high contrast is very helpful for image clarity, detail representation and gray level representation. the contrast enhancement of full-color led display is mainly to improve the brightness of the led display and reduce the surface reflectance of the display. however, the brightness is not the higher the better, too high, but the opposite will happen. it will not only affect the life of the led display, but also cause light pollution to the environment and people. the special processing of the full-color led panel and led light emitting tube can reduce the reflectivity of the led panel and improve the contrast of the full-color led panel.
second, to improve the gray level of full-color led display, gray level refers to the series of brightness that can be distinguished from the darkest to the brightest in the single primary color brightness of full-color led display. the higher the gray level of full-color led display, the richer the color, the brighter the color; conversely, the display color is single and the change is simple. the improvement of gray level can greatly enhance the depth of color and increase the number of geometric layers of image color display.
3. reducing the dot spacing of the full-color led display and the dot spacing of the full-color led display can improve its clarity. the smaller the dot spacing of the full-color led display, the higher the pixel density of the unit area of the led display, the more details can be displayed, and the more delicate the screen display.
fourthly, the full-color led display screen is combined with the video processor. the led video processor can use advanced algorithms to modify the signal with poor image quality, perform a series of processing such as de-interlacing, edge sharpening, motion compensation, etc. to enhance the details of the image and improve the picture quality. video processor image scaling algorithm is used to ensure that the video image is scaled to the maximum extent to maintain the clarity and gray level of the image. in addition, the video processor is also required to have a wealth of image adjustment options and effects, and to process the brightness, contrast and gray level of the image, so as to ensure the screen output soft and clear picture.
