The full-color LED display is the main carrier of advertising and information broadcasting. How can we make the full-color LED display clearer? The following editor will give you a simple analysis:
1. Improve the contrast of full-color LED display
Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer and more eye-catching the image, and the brighter and brighter the color. High contrast is very helpful for image clarity, detail performance, and gray level performance. In some text and video displays with large black-and-white contrast, high-contrast full-color LED displays have advantages in black-and-white contrast, clarity, and integrity. Contrast has a greater impact on the dynamic video display effect. Because the light-dark transition in the dynamic image is faster, the higher the contrast, the easier it is for human eyes to distinguish such a conversion process. In fact, the contrast improvement of full-color LED display is mainly to increase the brightness of the full-color LED display and reduce the reflectivity of the screen surface. However, the brightness is not as high as possible. Too high brightness will affect the environment and the crowd. Full-color LED display LED panels and LED light-emitting tubes undergo special processing, which can reduce the reflectivity of the LED panel and increase the contrast of the full-color LED display.
Second, improve the gray level of the full-color LED display
The gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color of the full-color LED display. The higher the gray level of the full-color LED display, the richer the color and the brighter the color; vice versa , The display color is single, and the change is simple. The increase of the gray level can greatly increase the color depth, making the display level of the image color increase geometrically. The LED gray scale control level is 14bit~16bit, making 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 accuracy.
Third, reduce the dot pitch of the full-color LED display
Narrowing the dot pitch of a full-color LED display can improve its clarity. The smaller the dot pitch of a full-color LED display, the more delicate the screen display. But there must be mature technology as the core support, its input cost is relatively large, the price of the full-color LED display produced is also high, and the market is constantly developing towards the small-pitch LED display.
