With the rapid development of LED display, the widespread use of LED display rental and LED electronic display and other LED large screen products greatly promotes the rapid development of the profession, especially the use of LED display rental. As we all know, LED screen rental is the main carrier of advertising and information broadcasting, so the clarity of full-color LED screen is very necessary. What factors ultimately affect the clarity of full-color LED screen?
Top of the list, point distance: reducing the point distance of LED display rental can greatly improve its clarity. The smaller the point distance of LED display rental, the more delicate the picture is. However, there must be mature skills as the central support. The investment cost is relatively large, and the rental price of the LED display screen is also on the high side. Fortunately, the shopping malls are also developing towards small distance LED display screen.
Second, contrast: contrast is one of the key factors affecting the visual effect. Generally speaking, the higher the contrast is, the clearer the picture is, and the more vivid and beautiful the color is. High contrast is helpful to the clarity, details and gray level of the picture. In some text and video display with large contrast, high contrast led display has advantages in contrast, clarity and integrity. Contrast has a greater impact on the dynamic video display, because the light and shade change is faster in dynamic pictures. The higher the contrast is, the simpler the eyes are to distinguish such a change process.
Third, gray level: gray level refers to the brightness level from the darkest to the brightest in the single primary color brightness of LED display screen. The higher the gray level of LED display screen, the richer the color, and the more beautiful the color. On the contrary, the display color is single, and the change is simple. The progress of gray level can greatly improve the color depth, and make the display level of picture color increase geometrically. The LED gray control level is 14bit ~ 16bit, which makes the picture level, detail resolution and display function of high-end display products reach the world advanced level. With the development of hardware skills, led gray level will continue to develop to higher control accuracy.
