With the development of the times, full-color LED display, as the main carrier of advertising and information updating, has become the trend of the times. High definition video often gives people a shocking visual experience and more realistic performance. The completion of high-definition display has two parts. One is that the source requests Full HD, and the other is that the screen requests Full HD. In fact, full-color LED display is developing towards high-definition display. How can we make the LED full-color display clearer?
1、 Improve the contrast of LED full-color display.
Contrast is an important factor affecting the visual effect. Generally speaking, the higher the illumination, the brighter the image and the brighter the color. High contrast illuminance helps to improve the clarity, detail effect and gray performance of the image.
For some large black and white text, video display and high light full-color LED display have advantages in black-and-white contrast, clarity and integrity. Contrast has a greater impact on the effect of dynamic video phenomenon. Due to the fast light dark conversion speed of dynamic images, the higher the degree of illumination, the easier it is for human eyes to distinguish this process. In fact, the improvement of non cooperative scheduling of full-color LED display is mainly to reduce the brightness and screen appearance reflectivity of full-color LED display. However, the higher the brightness, the better. It will not be too high, but will have a reaction. Now light pollution has become a hot spot. It can affect the environment and people. Led full-color screen and LED lamp tube can stop special process treatment, reduce the reflectivity of LED panel and improve the non cooperative scheduling of LED display screen.
2、 Improve the gray level of full-color LED display.
Gray level is a brightness series that can be distinguished between the basic color and the darkest brightness by the true color LED display screen. The higher the gray level of full-color LED display, the richer the color and the more gorgeous the color. And vice versa, the color is simple. The increase of gray level greatly improves the depth of color, and displays the color of the image in an exponential way. LED brightness is controlled between 14bit and 16bit, and high-end display products have reached the international advanced level in image level resolution and detail display effect. With the development of hardware technology, the gray level of LED has high control accuracy at any time.
