1. Contrast: Contrast is one of the primary conditions that affect visual impact. Generally speaking, the higher the contrast, the clearer and more conspicuous the image, and the more unique and vivid the color. High contrast is very helpful for the sharpness of the image, the main performance of the key points, and the main performance of the gray level. In some texts and videos with a large gap between black and white, high-contrast full-color LED displays have advantages in terms of black and white gap, clarity, and consistency. Contrast for dynamic pictures shows that the actual effect is higher, because the transition between light and dark in a dynamic image is faster, and the higher the contrast, the easier it is for human eyes to distinguish the whole process of such a transformation.
2. Gray level: Gray level refers to the chromaticity equivalence level of the single basic color of the full-color LED display from very dark to the most beautiful. The higher the gray level of the full-color LED display, The more colorful the color, the brighter the color; on the contrary, it shows that the color is single and the change is easy. The increase of the gray level can greatly increase the depth of the color, and promote the display level of the image color to increase in a geometric total. The LED gray scale control level is 14bit~16bit, which promotes the high-end display of the key points of the image level of the product and the display of the actual effect to achieve the global excellent level. Along with the technical development trend of hardware configuration, the LED gray scale will continue to develop towards higher linearity.
3. Dot spacing: Decreasing the dot spacing of a full-color LED display can greatly improve its clarity. The smaller the dot spacing of a full-color LED display, the more detailed the interface. However, for this, there must be complete technicality as the key application. The capital investment cost is relatively high. The price of the full-color LED display produced is also higher. Fortunately, the sales market is also moving towards small-pitch LED displays. Screen development trend.
