with the rapid development of society, led display rental panel screen can be seen everywhere. as the main carrier of advertising and information broadcasting, in the contemporary era, more and more follow the trend of the times. hd videos can often bring more shocking visual experience and show more real content. so how to make the led display more hd? this article is for your analysis.
in order to achieve high-definition display, there must be four factors: one is the requirement of full-hd chip source, the other is that the display should support full-hd, the third is to reduce the point spacing of the led display screen, and the fourth is the combination of the led display screen and the video processor. full-color led display is also moving towards higher-definition display.
i. improving the contrast of full-color led display screen
contrast is one of the key factors affecting visual effect. generally speaking, the higher the contrast, the clearer the image and the brighter the color. high contrast is very helpful for image clarity, detail representation and gray level representation. in some text and video display with large black-white contrast, high contrast full-color led display has advantages in black-white contrast, clarity, integrity and so on. contrast has a greater impact on the dynamic video display effect. because of the fast light-dark conversion in the dynamic image, the higher the contrast, the easier the human eye can recognize the conversion process.
in fact, the contrast improvement of full-color led display is mainly to improve the brightness of full-color led display and reduce the surface reflectance of the screen. 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. light pollution has become a hot topic nowadays. excessive brightness will affect 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.
2. improving the gray level of full-color led display screen
gray level refers to the series of brightness that can be distinguished from the darkest to the brightest in the monochrome brightness of full-color led display screen. the higher the gray level of full-color led display screen, 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. the gray control level of led is 14 bit to 16 bit, which makes the image level resolution details and display effect of high-end display products reach the world advanced level. with the development of hardware technology, the gray level of led will continue to develop towards higher control accuracy.
3. reducing the point spacing of full-color led display screen
reducing the dot spacing of full-color led display can improve its clarity. the smaller the dot spacing of full-color led display, the more delicate the screen display. however, mature technology must be the core support for this. its investment cost is relatively high, and the price of full-color led display is also high. fortunately, the market is also developing towards small-spacing led display.
