As the main carrier of advertising and information broadcasting, the full-color LED display is definitely the clearer you can see, the better the effect it will show. Although the smaller the dot pitch, the clearer the picture quality of the LED display, but the corresponding price is higher. What if we want to improve the clarity of the full-color LED display under the same dot pitch? Next, I will provide you with 3 ways to improve the clarity of the full-color LED display.
1. Improve the contrast of full-color LED display
Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer and more eye-catching the image, and the brighter and brighter the color. High contrast is very helpful for image clarity, detail performance, and gray 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, and integrity. Contrast has a greater impact on the dynamic video display effect. Because the light-dark transition in the dynamic image is faster, the higher the contrast, the easier it is for human eyes to distinguish such a conversion process.
In fact, the contrast improvement of full-color LED display is mainly to increase the brightness of the full-color LED display and reduce the reflectivity of the surface of the screen. However, the brightness is not as high as possible. Too high brightness will affect the environment and the crowd. Full-color LED display LED panels and LED light-emitting tubes undergo special processing, which can reduce the reflectivity of the LED panel and increase the contrast of the full-color LED display.
2, 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 primary color brightness of the full-color LED display. The higher the gray level of the full-color LED display, the richer the color and the brighter the color; , The display color is single, and the change is simple. The increase of the gray level can greatly increase the color depth, making the display level of the image color increase geometrically. The LED gray scale control level is 14bit~16bit, making the image level resolution details and display effects of high-end display products reach the world's advanced level. With the development of hardware technology, LED gray scale will continue to develop to higher control accuracy.
3. Appropriately increase the brightness of the LED display
Properly increasing the brightness of the LED display screen can make the picture quality clearer. LED display screens are different according to the lamp beads and IC used, as well as indoor and outdoor use, and their controllable brightness is also different. Normally, on the basis of not being too glaring, increasing the brightness value of 100-200 can better improve the clarity of the picture.
It should be noted that we cannot blindly adjust the brightness of the LED display to too high in pursuit of higher definition, not only the LED lamp beads and IC, but in many cases, when the LED display leaves the factory, it is already based on the prior art. The foundation has done heat dissipation, blindly increase the brightness, but the heat dissipation is not done well, there is a possibility of short circuit and burn out the display.
