How to Make LED Display Higher Definition?

With the continuous advancement of science and technology in recent years, LED displays have been recognized and applied in various industries. The displayed content is becoming more and more high-definition. How can the LED display achieve high-definition display? First, the image and video source requires full HD. Second, the LED display is required to support full HD. Third is to reduce the pixel pitch of the LED display. The fourth is the combination of led display and video processor. At present, LED full-color displays are also moving towards higher-definition displays.

1, Improve the contrast ratio of the full color LED display. Contrast ratio is one of the key factors affecting visual effects. Generally speaking, the higher the contrast, the clearer the image and the brighter the color. High contrast is very helpful for image clarity and gray level performance. In some text and video displays with large black and white contrast, the high-contrast full color LED display has advantages in black and white contrast, sharpness, and integrity. Contrast has a greater impact on the display effect of dynamic video. Because the light and dark transition in dynamic images is relatively fast, the higher the contrast, the easier it is for human eyes to distinguish such a transition process. In fact, the improvement of the contrast ratio of the full color LED screen is mainly to improve the brightness of the full-color LED display and reduce the surface reflectivity of the screen. However, the brightness is not as high as possible, too high, but it will be counterproductive, not only affecting the LED display. life, but also cause light pollution. The RGB LED display LED module and LED light-emitting tube undergo special processing, which can reduce the reflectivity of the LED panel and improve the contrast of the RGB LED display.

2, Improve the gray level of full color LED video wall. The gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness of the full-color LED display. The higher the gray level of the full-color LED display, the richer the color and the brighter the color. The improvement of the gray level can greatly improve the color depth, so that the display level of the image color increases geometrically. The LED gray scale control level is 14bit~20bit, which makes the image level resolution details and display effects of high-end display products reach the world’s advanced level. With the development of hardware technology, LED gray scale will continue to develop to higher control precision.

3, Reduce the pixel pitch of the full color LED display. Reducing the pixel pitch of the full-color LED display can greatly improve its clarity. The smaller the dot pitch of the full-color LED display, the finer the display. However, the price of small-pitch LED displays is on the high side. Fortunately, the market is now developing towards small-pitch LED displays.

4, LED display combined with video processor. The LED video processor can use advanced algorithms to modify the signal with poor image quality, perform a series of processing such as de-interlacing, edge sharpening, motion compensation, etc., to enhance the details of the image and improve the picture quality. The video processor image scaling processing algorithm is used to ensure that after the video image is scaled, the clarity and gray level of the image are maintained to the greatest extent. In addition, the video processor also needs to have rich image adjustment options and adjustment effects, and process the image brightness, contrast, and grayscale to ensure that the screen outputs a soft and clear picture.
