At present, in order to achieve high-definition display effect, full-color LED display generally needs two basic prerequisites, one is that the video itself must be high-definition, and the other is that the LED display you use must support high-definition display.
With the development of society and the progress of science, people have higher and higher requirements for the display effect of LED display screen. High definition and ultra high definition display have gradually become the mainstream of the market. The shocking effect of high-definition video images is very strong. Compared with the traditional video images, the content displayed by high-definition video images is more attractive and can better meet people’s pursuit of high-quality audio-visual. In addition to the two basic prerequisites mentioned above, how to make the full-color LED display more HD?
Four tips to teach you how to make full color LED display become high definition in seconds
High definition LED display
1、 Improve the contrast of full-color LED display: contrast is one of the key factors affecting the visual effect. Generally speaking, the higher the contrast is, the clearer the image is, and the brighter the color is. High contrast is very helpful to the definition, detail and gray level of the image. In some text and video displays with large black-and-white contrast, high contrast full-color LED display has advantages in black-and-white contrast, clarity, integrity and so on. Contrast has a greater impact on the dynamic video display effect. Because the light dark conversion in dynamic images is faster, the higher the contrast, the easier it is for human eyes to distinguish the image conversion process. The contrast enhancement of full-color LED display is mainly to improve the brightness of the LED display and reduce the surface reflectance of the display. However, the brightness is not the higher the better. If it is too high, it will backfire. It will not only affect the life of the LED display, but also cause light pollution and have adverse effects on the environment and people. The LED panel and LED light-emitting tube of full-color LED display screen are processed by special technology, which can reduce the reflectivity of LED panel and improve the contrast of full-color LED display screen.
2、 Improve the gray level of full-color LED display: the gray level of LED display refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness. The higher the gray level of full-color LED display, the richer the color, and the more gorgeous the color; on the contrary, the display color is single and simple. The improvement of gray level can greatly enhance the color depth, and make the display level of image color increase geometrically. Now many LED display manufacturers can make the gray level of the display screen to be 14bit ~ 16bit, so that the image level can distinguish the details and display effect more delicate, realistic and colorful.
3、 Reduce the point spacing of full-color LED display: reducing the point spacing of full-color LED display can improve the clarity of display screen, because the smaller the point spacing is, the higher the pixel density of LED display per unit area is, the more details can be displayed, and the more delicate the display is.
4、 The combination of LED display and video processor: 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, enhance the image display details and improve the image display quality. Using video processor image scaling algorithm, to ensure that the video image after scaling processing, the maximum degree of image clarity and gray level; in addition, the video processor is also required to have a wealth of image adjustment options and adjustment effect, image brightness, contrast, gray processing, to ensure that the LED display output soft and clear picture.
