The realization of led high-definition full-color display requires two basic premises. One is that the video source must be HD, and the other is that the LED high-definition full-color display must support HD.

With the development of society, people have higher and higher requirements for the display effect of LED high-definition full-color displays, and HD and ultra HD have gradually become the mainstream of the market. HD video images bring great shock. Compared with traditional video images, its display content is more attractive and can satisfy people's pursuit of high-quality audiovisual. So, in addition to the two basic premises mentioned above, how can we make the led high-definition full-color display more high-definition?

Improve the contrast of full-color led high-definition full-color display: Contrast is an important factor that affects the display effect. Generally speaking, the greater the contrast, the clearer and more vivid the picture, and the more vivid the color. This helps to improve the clarity, detail and grayscale performance of the image. For some larger text and video displays, high-contrast LED high-definition full-color displays have advantages in black and white contrast, clarity, and integrity. Contrast is an important factor affecting dynamic video display. Because the light-dark conversion speed of dynamic pictures is faster and the contrast ratio is higher, it is easier for the human eye to distinguish the conversion process of the picture. Improving the contrast of the led high-definition full-color display is mainly to improve the brightness of the led high-definition full-color display and the reflectance of the display surface. However, the higher the brightness is not the better, the higher, on the contrary, it will affect the life of the led high-definition full-color display, and will also have an adverse impact on the environment and people. Brightness of led high-definition full-color display. PlusLED display screen can also improve reflectivity through special technology.

Improve the gray level of the LED high-definition full-color display: The gray level of the LED display refers to the brightness of a single basic color, from the darkest to the brightest, the brightness level that can be distinguished. The higher the gray level of the entire ED display, the richer and brighter the color. On the contrary, the simpler the displayed color, the simpler the change. Increasing the gray level can greatly increase the depth of the color and increase the display level geometry of the image color. Now many manufacturers of LED high-definition full-color display screens can increase the gray level of the display screen to 14bit~16bit, making the picture level difference more detailed and lifelike, and the display effect is more gorgeous.

The point spacing of the led high-definition full-color display screen is reduced: the point spacing of the led high-definition full-color display screen is reduced, which can improve the definition of the display. The smaller the dot pitch, the higher the pixel density per unit area of the led high-definition full-color display, the more details that can be displayed, and the more delicate and vivid the picture.
