1、 Improve the contrast of LED display
Contrast is one of the key factors affecting visual effect. Generally speaking, the higher the contrast, the clearer and more eye-catching the image, and the more vivid and gorgeous the color. High contrast is conducive to image clarity and gray-level detail expression. In some texts, video displays with large black and white contrast and full-color LED displays with high contrast have advantages in black and white contrast, clarity and integrity. Contrast has a greater impact on dynamic video display. Because the shading conversion in dynamic images is faster, the higher the contrast, the easier it is for the human eye to distinguish the conversion process. In fact, the contrast improvement of the full-color LED display is mainly to improve the brightness of the full-color LED display and reduce the reflectivity of the screen surface, but the brightness is not the higher the better, the higher the brightness, but will cause its reflection pollution to become a hot topic, and the higher the brightness will have an impact on the environment and people. The special processing of LED panel and LED lamp tube of full-color LED display can reduce the utilization rate of LED panel and also improve the contrast of full-color LED display.
2、 Increase the gray level of LED display
Gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness of the full-color LED display. The higher the gray level of the full-color LED display, the richer the color, and the more gorgeous the color. The increase of gray level can greatly improve the color depth, thus making the image color display level increase geometrically. The LED gray control level is 1401 * 16, which makes the image resolution details and display effect of high-end display products reach the world's advanced level. With the development of hardware technology, LED gray scale will continue to develop towards higher control accuracy.
3、 Reduce the dot spacing of full-color LED display
Reducing the dot spacing on the true color LED electronic screen can improve the definition, and the smaller the dot spacing on the true color LED electronic screen, the more refined the display screen. However, it is necessary to have a proven technology as the core support. The investment is relatively high, and the price for producing full-color led displays is also high, but the market is now turning to small-space led displays.
