With the rapid development of LED display screens, full-color LED display screens, as the main carrier of advertising and information broadcasting, 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.
Full color LED display
Contrast
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.

Dot pitch
Dot spacing: reducing the dot spacing of a full-color LED display can improve its clarity. The smaller the dot spacing 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.

Gray scale
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 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; , 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 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.
