Grasping the following four factors, LED display is more HD?
LED display has received wide attention since its birth. With the continuous improvement of installation technology in recent years, it has been approved by various industry fields. LED display production and maintenance also requires professional knowledge, how to achieve high-definition display? To achieve high-definition display must have four factors: First, the film source requires full HD; Second, the display requirements can support full HD; Third, reduce the LED display The dot spacing of the screen; the fourth is the combination of the LED display and the video processor. At present, LED full color display is also moving towards higher definition display.
01. Improving the contrast contrast of the LED full-color display is one of the key factors affecting the visual effect. Generally speaking, the higher the contrast, the clearer and more conspicuous the image, and the more vivid 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 LED full-color screen 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. Life expectancy can also cause light pollution. Light pollution has become a hot topic now, and 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.
02. Improve the gray level of the full-color display of the LED. It refers to the brightness level that can be distinguished from the darkest to the brightest in the brightness of the single-color color of the LED full-color screen. The higher the gray level of the full-color LED display of Yunhai Guangcai High, the richer the color, the more vivid the color; 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, so that 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 gray levels will continue to develop toward higher control precision.
03. Reduce the dot spacing of the LED full-color display to reduce the dot spacing of the LED full-color display, which can improve the sharpness of the LED display. The smaller the dot spacing of the full-color LED display, the finer the screen display. However, this point must have mature technology as the core support, and its input cost is relatively large, and the price of the full-color LED display produced by the company is also high, but fortunately, the market is also developing toward the small-pitch LED display.
04. LED full color display and video processor combined with LED video processor can use advanced algorithms to modify the signal with poor image quality, perform deinterlacing, edge sharpening, motion compensation, etc., enhance the image. Details, improve 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 also 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.
