Small-pitch LED display essential elements for improved clarity
Full-color small-pitch LED display as the main carrier of advertising and information broadcasting, in the contemporary, more and more follow the trend of the times. High-definition video can often bring a more dramatic visual experience, and the content displayed will be more realistic. There are two influencing factors to achieve high-definition display. One is that the film source requires full HD, and the other is that the display requires full HD. The full-color small-pitch LED display is actually moving toward a higher-definition display. So, how do we make the full-color small-pitch LED display clearer?
First, improve the contrast of full-color small-pitch LED display
Contrast is one of the key factors affecting visual effects. Generally speaking, the higher the contrast, the sharper and more conspicuous the image, and the more vivid the color. High contrast is very helpful for the sharpness, detail performance and gray level performance of the image. The contrast of the small-pitch LED display is up to 5000:1. In some text and video displays with large black and white contrast, high contrast Color LED display has advantages in black and white contrast, clarity and integrity. Contrast has a greater impact on the dynamic video display. Because the light and dark transitions in the dynamic image are faster, the higher the contrast, the easier it is for the human eye to distinguish such a 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. However, the brightness is not as high as possible, too high, but it will be counterproductive, and light pollution becomes hot now. On the topic of discussion, excessive brightness will have an impact on the environment and the population. The full-color LED display LED panel and LED lighting tube are specially processed to reduce the reflectivity of the LED panel and also improve the contrast of the full-color LED display.
Second, improve the gray level of full-color small-pitch LED display
The gray level refers to the brightness level that can be distinguished from dark to bright in the single base color brightness of the full color LED display. The higher the gray level of the full color LED display, the richer the color, the more vivid the color; otherwise, the display The color is single and the change is simple. The increase of the gray level can greatly increase the color depth, so that the display level of the image color increases geometrically. The LED gray level control level is 14bit~16bit, which makes the image level resolution details and display effects of high-end display products reach the world advanced level. With the development of hardware technology, LED gray levels will continue to develop toward higher control precision.
Third, reduce the dot spacing of full-color small-pitch LED display
Reducing the dot pitch of the full-color LED display can improve its sharpness. The smaller the dot pitch of the full-color LED display, the finer the screen display. At present, the concept of "micro-pitch" has appeared in the industry, which means that the display point spacing specification is below P2.0, and the lamp bead diameter is not more than 1 mm. This point must have mature technology as the core support, the input cost is relatively large, and the price of the full-color LED display produced by the company is also high, but fortunately the market is also developing towards the small-pitch led display.
