How to improve display clarity?

 

 

As the main carrier of advertising and information playback, the full-color small-pitch LED display is now more and more following the trend of the times. High-definition video tends to give people a more stunning visual experience and the content they show is more realistic. There are two influencing factors to achieve high-definition display, one is that the source of the film requires full HD, and the other is that the display requires full HD. How can we make the full-color small-pitch LED display clearer?

 

1. 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 clearer and more eye-catching the image, and the more vivid and vivid the colors. High contrast is of great help to the clarity of the image, detail performance, gray level performance, in some black and white contrast text, video display, high contrast full-color LED display has advantages in black and white contrast, clarity, integrity, etc. Contrast has a greater impact on the display effect of dynamic video, because the transition between light and dark in dynamic images is relatively fast, the higher the contrast, the easier it is for human eyes to distinguish such a conversion process. Improve the brightness of the full-color LED display and reduce the reflectivity of the screen surface, however, the brightness is not the higher the better, too high, but counterproductive, light pollution has become a hot topic now, too high brightness will have an impact on the environment and the crowd. Full-color LED display LED panel and LED light-emitting tube are treated with special technology, which can reduce the reflectivity of the LED panel and improve the contrast of the full-color LED display.

 

2. Improve the gray level of full-color small-pitch LED display

Gray level refers to the brightness level that can be distinguished from dark to bright in the single primary color brightness of full-color LED display, the higher the gray level of full-color LED display, the richer the color, and the more gorgeous the color! On the contrary, the display color is single and the change is simple. The increase of gray level can greatly improve the color depth, so that the display level of image color increases geometrically. The LED gray scale control level is 14bit~16bit, which makes the image level resolution details and display effect of high-end display products reach the world's advanced level. With the development of hardware technology, the gray level of LED will continue to develop to higher control accuracy.

 

3. Reduce the dot spacing of full-color small-pitch LED displays

Reducing the dot spacing of the full-color LED display can improve its clarity very well, and the smaller the dot spacing of the full-color LED display, the more delicate the picture display. At present, the concept of "micro spacing" has appeared in the industry, which means that the display point spacing specification is below P2.0 and the diameter of the lamp bead is not more than 1 mm. At this point, 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 now the market is also developing towards small pitch LED display.
