LED electronic screen how to improve the clarity
High-definition video can often bring people a more shocking visual experience, and the content displayed will be more realistic. To achieve high-definition display of LED electronic screen, there must be two factors, one is that the film source requires full high-definition, and the other is that the display must support full high-definition. The full-color LED display is actually moving towards a higher-definition display, so how can we make the full-color LED display clearer?
1. Improve the contrast of the full-color LED display Contrast is one of the key factors affecting the 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 performance, and grayscale performance. In some text and video displays with large black and white contrast, the high-contrast LED display has advantages in black and white contrast, sharpness, and integrity. Contrast has a greater impact on the display effect of dynamic video. Because the light and dark transition in dynamic images is relatively fast, the higher the contrast, the easier it is for human eyes to distinguish such a transition process.
The contrast improvement of the LED display is mainly to improve the brightness of the full-color LED display and reduce the surface reflectivity of the screen. However, the brightness is not as high as possible, too high, but it will be counterproductive, and light pollution has become a hot topic. Topic, too high brightness will have an impact on the environment and people. The full-color LED display LED panel and LED light-emitting tube undergo special processing, which can reduce the reflectivity of the LED panel and improve the contrast of the full-color LED display.
2. Improve the gray level of LED display The gray level refers to the number of brightness levels that can be distinguished from the darkest to the brightest in the single-color brightness of the full-color LED display. The gray level of the full-color LED display is higher. High, the richer the color, the brighter the color; on the contrary, the display color is single and the change is simple. The improvement of the gray level can greatly improve the color depth, so that the display level of the image color increases geometrically. The LED grayscale control level is 14bit~16bit, which makes the image level resolution details and display effects of high-end display products reach the world’s advanced level. With the development of hardware technology, LED gray scale will continue to develop to higher control precision.
3. Reduce the dot pitch of the full-color LED display. Reducing the dot pitch of the full-color LED display can improve its clarity. The smaller the dot pitch of the full-color LED display, the finer the display. However, this point must be supported by mature technology. Its input cost is relatively large, and the price of the full-color LED display produced is also high. Fortunately, the market is now developing towards small-pitch LED displays.
