How to enhance the clarity of LED display
As the society develops faster and faster, the LED display screen can be seen everywhere. As the main carrier of advertising and information broadcasting, in the contemporary era, it is increasingly following the trend of the times. High-definition video can often bring a more dramatic visual experience, and the content displayed will be more realistic. So how to make the led display more HD? Next we analyze and analyze together:
To achieve high-definition display, there must be four factors. One is that the film source requires full HD, the second is that the display requires support for full HD, the third is to reduce the dot spacing of the led display, and the fourth is the combination of the led display and the video processor. The full-color LED display is actually moving toward a higher definition display.
First, improve the contrast of full color LED display
Contrast 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 sharpness, detail performance, and gray level performance. In some text and video displays with large contrasts in black and white, high-contrast full-color LED displays have advantages in black-and-white contrast, sharpness, and integrity. Contrast has a greater impact on the dynamic video display. Because the light and dark transitions in the dynamic image are faster, the higher the contrast, the easier it is for the human eye to distinguish such a conversion process.
In fact, the contrast improvement of the full-color LED display is mainly to improve 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, too high, but it will be counterproductive, not only affecting the LED display. The life of the screen can also cause light pollution. Light pollution has become a hot topic nowadays. Excessive brightness will have an impact on the environment and people. The full-color LED display LED panel and LED lighting tube are specially processed to reduce the reflectivity of the LED panel and also improve the contrast of the full-color LED display.
Second, improve the gray level of full color LED display
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, the more vivid the color; The display color is single and the change is simple. The increase of the gray level can greatly increase the color depth, and the display level of the image color increases geometrically. The LED gray level control level is 14bit~16bit, which makes the image level resolution details and display effects of high-end display products reach the world advanced level. With the development of hardware technology, LED grayscale will continue to develop to higher control accuracy.
Third, reduce the dot spacing of full color LED display
Reducing the dot pitch of the full-color LED display can improve its sharpness. The smaller the dot pitch of the full-color LED display, the finer the picture display. However, this point must have mature technology as the core support, the input cost is relatively large, and the price of the full-color LED display produced by the company is also high. Fortunately, the market is also developing towards the small-pitch led display.
Fourth, led display combined with video processor
The LED video processor can use advanced algorithms to modify the signal with poor image quality, perform deinterlacing, edge sharpening, motion compensation and other processing to enhance the details of the image and improve the picture quality. The video processor image scaling processing algorithm is used to ensure that the video image is scaled and processed to maximize the sharpness and gray level of the image. In addition, the video processor is required to have rich image adjustment options and adjustment effects to process image brightness, contrast, and grayscale to ensure a soft and clear screen output.
