Necessary elements for improving the definition of small-pitch LED display

The full-color small-pitch LED display is the main carrier of advertising and information broadcasting. In the contemporary era, it is increasingly following the trend of the times. High-definition video often gives people a more stunning visual experience, and the displayed content 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 monitor is required to support Full HD. Full-color small-pitch LED display is actually moving towards higher-clear display, then, how do we make full-color small-pitch LED display more clear?

First, improve the contrast of full-color small pitch LED display

Contrast is one of the key factors affecting the visual effect. In general, the higher the contrast, the clearer the image is and the brighter the color is. High contrast is very helpful for the sharpness of the image, detail performance, grayscale performance, the construction of a small pitch LED display with a contrast ratio of up to 5000:1, in some text and video display with large black and white contrast, high contrast Color LED display has advantages in terms of black and white contrast, sharpness, and integrity. Contrast has more influence on the dynamic video display effect. Because the light and shade conversion in the dynamic image is faster, the higher the contrast, the easier the human eye can distinguish the conversion process. In fact, the contrast improvement of full-color LED display screens is mainly to increase the brightness of full-color LED display screens and reduce the surface reflectivity of screens. However, the brightness is not as high as possible. Too high, it will backfire, and light pollution becomes hot now. The topic of discussion is that high brightness will have an impact on the environment and people. Full-color LED display The LED panel and LED light-emitting tube undergo special processing to reduce the reflectivity of the LED panel and improve the contrast of the full-color LED display.

Second, improve the full-color small pitch LED display grayscale

Gray scale refers to the brightness level that can be distinguished from dark to bright in the single-color brightness of a full-color LED display screen. The higher the gray level of a full-color LED display, the richer the color and the brighter the color; Single color, simple change. The increase in gray level can greatly increase the color depth, so that the display level of the image color increases geometrically. LED gray scale control level is 14bit~16bit, which makes the high-level display product's image level resolution detail and display effect reach the world advanced level. With the development of hardware technology, LED gray scale will continue to develop higher control accuracy.

Third, reduce the distance between full-color small pitch LED display

Reducing the dot pitch of full-color LED displays can improve its sharpness. The smaller the dot pitch of the Maipu glory full-color LED display, the finer the picture display. At present, the concept of "fine-pitch" has appeared in the industry, which means that the display pitch spacing specification is below P2.0, and the lamp bead diameter should not exceed 1 mm. This point, must have mature technology as the core support, the input cost is relatively large, the full-color LED display produced by the price is also high, but fortunately the market is also moving towards a small pitch led display development.
