As the main carrier of advertising and information broadcasting, full-color LED display screens are increasingly following the trend of the times in the contemporary era. High-definition video can often give people a more shocking visual experience, and the content displayed will be more realistic. To achieve high-definition display, there must be two factors, one is that the source requires full high-definition, and the other is that the display needs to 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? Let's take a rough analysis below.
(1) Improve the contrast of the full-color LED display
Contrast is one of the key factors affecting visual effects. 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 full-color LED display and reduce the reflectivity of the surface of the screen. However, the brightness is not as high as possible, too high, but it will be counterproductive, and light pollution has become the current heat. The topic of discussion, too high brightness will have an impact on the environment and the crowd. Full-color LED display LED panels and LED light-emitting tubes are treated with special processes, which can reduce the reflectivity of the LED panel and increase the contrast of the full-color LED display.
(2) 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 brightness of a full-color LED display. The higher the gray level of a full-color LED display, the richer the color and the brighter the color; , 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 control level is 14bit16bit, 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.
(3) 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. However, mature technology must be used as the core support for this. The input cost is relatively large, and the price of the full-color LED display produced is also high. Fortunately, the market is also developing towards small-pitch LED displays.
