Improve the contrast of the LED display: Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer and more vivid the image, and the brighter and brighter the color. High contrast is very helpful for image clarity, detail performance, and gray level performance.
Increase the gray level of the LED display: the gray level of the LED display refers to the brightness level that can be distinguished from the darkest to the brightest of the single primary color brightness. The higher the gray level of the LED display, the richer the color , The color is brighter; on the contrary, the display color is single and the change is simple. The increase of the gray level can greatly increase the color depth, making the display level of the image color increase geometrically. Nowadays, many LED display manufacturers can set the gray scale of the display to 14bit~16bit, so that the image level can distinguish the details and the display effect is more delicate, vivid, and colorful.
Narrowing the dot pitch of the LED display: narrowing the dot pitch of the LED display can greatly improve the clarity of the display screen, because the smaller the dot pitch, the higher the pixel density per unit area of the LED display, and the more details that can be displayed More, the screen display is more delicate and lifelike.
The combination of LED display and video processor: The LED video processor can use advanced algorithms to modify signals with poor image quality, and perform a series of processing such as de-interlacing, edge sharpening, and motion compensation to enhance image display details and improve Picture display quality. The video processor image scaling processing algorithm is used to ensure that the video image is scaled to maintain the sharpness and gray level of the image to the greatest extent; in addition, the video processor is also required to have a wealth of image adjustment options and adjustment effects. Brightness, contrast, and grayscale are processed to ensure that the LED display outputs a soft and clear picture.
