The full-color LED display is the main carrier for advertising and information broadcast. How can we make the full-color LED display clearer? The following Yigechuang editor will give you a simple analysis of the following points:
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 more vivid the colors. High contrast is very helpful to the image’s sharpness, detail performance and gray level performance. In some text and video displays with large black-and-white contrast, the high-contrast full-color LED display has advantages in black-and-white contrast, clarity, and integrity. Contrast has a greater influence on the display effect of dynamic video. Since the light and dark conversion in the dynamic image is faster, the higher the contrast, the easier it is for the human eye to recognize such a conversion process. In fact, the improvement of the contrast of the full-color LED display is mainly to increase the brightness of the full-color LED display and reduce the surface reflectance of the screen body. However, the brightness is not as high as possible, too high brightness will affect the environment and the crowd. The full-color LED display LED panel and LED light-emitting tube are specially processed to reduce the reflectivity of the LED panel and improve the contrast of the full-color LED display.
2.Improve the gray scale of full-color LED display
The gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the brightness of 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 more colorful the color; , 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 gray scale control level is 14bit, 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, the gray scale of LED display screen will continue to develop towards higher control accuracy.
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 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 small-pitch LED display.
