contrast
contrast is one of the first conditions affecting visual impact, generally speaking, the higher the contrast, the clearer the image, the more unique and vivid color. high contrast for the clarity of the image, key points of the main performance, the main performance of the gray level is very helpful. in some text and video shows with a large gap between black and white, the high-contrast full-color led display has advantages in the black and white gap, clarity, consistency and other levels. contrast for dynamic images shows that the actual effect is higher, because the dynamic image of the light and dark boundary change is faster, the higher the contrast, the more easily the human eyes can distinguish the whole process of that transformation.
2, gray level
gray level refers to the full color led display single basic color from very dark to the most beautiful middle can be different color ratio series, the higher the gray level of the full color led display, the more colorful color, the more bright color; on the contrary, it shows that the tone is single and the transformation is easy. the enhancement of gray level can greatly improve the color depth and promote the geometric total of the color representation level of the image. led grayscale manipulation level is 14bit~16bit, which promotes the high-grade image level of the product to distinguish the key points and shows that the actual effect has achieved a global excellent level. with the development trend of hardware configuration technology, the led gray level will continue to develop towards a higher linearity.
3. point spacing
the point spacing of the full-color led display can very well improve its clarity, and the smaller the point spacing of the full-color led display, the more detailed the interface indicates. however, at this point, it is necessary to have perfect technology as the key application, the cost of capital investment is relatively large, and the price of the full-color led display produced is also high, but fortunately, the sales market is also developing toward small-pitch led display.
