As the main carrier of information broadcasting and advertising, the full-color LED display is more and more follow-up trend in the contemporary era. High-definition video often gives people a more vibrating visual experience, and the content displayed will become more real. There are two elements to complete HD presentation. One is that the source requests Full HD, and the other is that the display request supports Full HD. The full-color LED display is actually moving toward a higher-definition display. So, after all, how to improve the clarity of the full-color LED display, let’s take a rough look at it.
First of all, to improve the illuminance of the full-color LED display, the illuminance is one of the key factors affecting the visual effect. Generally speaking, the higher the illuminance, the clearer and more conspicuous the image, and the more vivid the color. High illuminance is very helpful in terms of image clarity, detail performance, and gray level performance. In some text and video displays with large contrast between black and white, the high-illumination full-color LED display has advantages in black-and-white contrast, clarity, and integrity. The illuminance has a greater influence on the dynamic video display effect. Since the light and dark conversion in the dynamic image is faster, the higher the illuminance, the easier it is for the human eye to distinguish such a conversion process.
In fact, the improvement of the illuminance of the full-color LED display is mainly to improve the brightness of the full-color LED display and reduce the reflectance of the external surface of the screen. However, the brightness is not higher, the better, too high, but it will be counterproductive, and light pollution has become The hot topic of discussion is that it will have an impact on the environment and the population. The full-color LED display LED panel and LED lighting tube stop special process disposal, which can reduce the reflectivity of the LED panel, and can also improve the illuminance of the full-color LED display.
Secondly, improve the gray level of the full-color LED display. The gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the single-color color of the full-color LED display. The gray level of the full-color LED display. The higher the color, the more brilliant the color, and the brighter the color; on the contrary, the display color is simple and the change is simple. The advancement of the gray level can greatly increase the color depth, so that the display level of the image color increases geometrically. The LED grayscale 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 be carried out from time to time to higher control accuracy.
Finally, 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 finer the picture display. However, this must be supported by mature technology, and the investment cost is relatively large. The full-color LED display produced by the company is also expensive, but fortunately, the market is now moving toward small-pitch LED displays.
