Factors Affecting The Definition Of LED Full Color Display Screen

1. Contrast: contrast is one of the most important factors affecting visual impact. Generally speaking, the higher the contrast, the clearer the image and the more unique and bright the conspicuous color. For the main performance of image clarity and high contrast of key points, as well as the main performance of gray level, this is very helpful. For some text and video displays with large contrast difference between black and white, high contrast led full-color display has advantages in black-and-white contrast, clarity and consistency. For dynamic images, due to the fast change of light dark junction in dynamic images, the higher the contrast, the easier it is for both eyes to distinguish such transformation process.

2. Gray level: gray level refers to the equal proportion of the color from very dark to the brightest in the single primary color chromaticity of LED full-color display. The higher the gray level of LED full-color display, the brighter the color is. On the contrary, the color of LED full-color display is single, and the improvement of gray level can greatly improve the color depth, Thus, the display level of image color rises geometrically. With the continuous progress of hardware configuration technology, the LED gray level control level is increased from 14bit to 16bit, and the LED gray level will continue to improve the linearity.

3. Point spacing: the point spacing of LED full-color display can improve the clarity. The smaller the point spacing of LED full-color display, the more detailed the interface display. But this point must have perfect technology as the key application, its investment cost is very relative, the price of LED full-color display screen is high.
