Elements That Affect Display Clarity

Full-color LED display as the main carrier of advertising and information broadcasting, in contemporary times, more and more follow the trend of the times. High-definition video tends to give people a more powerful visual experience and the content displayed will be more realistic. There must be two factors to achieve high-definition display, one is that the source requires full HD, and the other is that the display needs to support full HD. Full-color LED display is actually moving towards a more high-definition display, so how do we make the full-color LED display clearer, below, let's roughly analyze.

Improve the contrast of full-color LED displays

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 a great help for image sharpness, detail performance, grayscale 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, integrity and other aspects. Contrast has a greater impact on the display effect of dynamic video, because the light and dark conversion in the dynamic image is relatively fast, the higher the contrast, the easier it is for the human eye to distinguish such a conversion process. In fact, the contrast improvement of full-color LED display is mainly to improve the brightness of full-color LED display and reduce the reflectivity of the screen surface, but the brightness is not as high as possible, too high, but will be counterproductive, light pollution has become a hot topic now, too high brightness will have an impact on the environment and people. Full-color LED display LED panel and LED light-emitting tube are treated in a special process, which can reduce the reflectivity of the LED panel and improve the contrast of the full-color LED display.

Improve the grayscale level of full-color LED display

Grayscale level refers to the brightness level that can be distinguished from the darkest to the brightest in the single-color brightness of the full-color LED display, the higher the grayscale level of the full-color LED display, the richer the color, the more vivid the color; On the contrary, the display color is single and the change is simple. The increase of grayscale level can greatly improve the color depth, so that the display level of image color increases geometrically. The LED grayscale control level is 14bit~16bit, so that the image level resolution details and display effects of high-end display products have reached the world's advanced level. With the development of hardware technology, LED grayscale will continue to develop to higher control accuracy.

Reduce the dot spacing of full-color LED displays

Reducing the dot spacing of the full-color LED display can improve its clarity well, and the smaller the dot spacing of the full-color LED display, the more delicate the picture display. However, this point, must have mature technology as the core support, its input cost is relatively large, the price of the full-color LED display produced is also high, but fortunately now the market is also developing towards small-pitch LED display.
