4 Points to improve the high definition of LED display

Improve the contrast of LED display

In some text and video displays with large black-and-white contrast, high-contrast full-color LED displays have advantages in black-and-white contrast, clarity, and integrity. Contrast has a greater impact on the display effect of dynamic video. Since the light and dark transitions in dynamic images are 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 of the LED full-color screen is mainly to increase the brightness of the full-color LED display and reduce the reflectivity of the screen surface. However, the brightness is not as high as possible. It also causes light pollution. Light pollution has become a hot topic now. Excessive brightness will have an impact on the environment and people. Full-color LED display The LED panel and LED light-emitting tube undergo special processing, which can reduce the reflectivity of the LED panel and improve the contrast of the full-color LED display.

Improve the gray scale of LED display

The gray level refers to the brightness series that can be distinguished from the darkest to the brightest in the single primary color brightness of the LED full-color screen. The higher the gray level of the LED display, the richer the color and the more gorgeous the color; otherwise, the display color is single , the change is simple. The improvement of the gray level can greatly enhance the color depth, so that the display level of the image color increases geometrically. The LED grayscale control level is 14bit~16bit, which makes the image level resolution details and display effect of high-end display products reach the world's advanced level. With the development of hardware technology, LED gray scale will continue to develop towards higher control precision.

Using Smaller pixel pitch of the LED display

Reducing the dot pitch of the full-color LED display can improve its clarity. The smaller the dot pitch of the full-color LED display, the more delicate the picture will be displayed. However, for this point, there must be mature technology as the core support, and its input cost is relatively high, and the price of the full-color LED display produced is also high, but fortunately, the market is now developing towards small-pitch LED displays.

Combination of LED display and 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 deinterlacing, edge sharpening, motion compensation, etc., to enhance the details of the image and improve the picture quality. The video processor image scaling algorithm is used to ensure that the video image is scaled and processed to maintain the clarity and gray level of the image to the greatest extent. In addition, the video processor is also required to have rich image adjustment options and adjustment effects to process image brightness, contrast, and grayscale to ensure that the LED screen outputs soft and clear images.
