Making LED display outdoor LED floor higher definition is not difficult. If we grasp these four factors

LED floor has been widely concerned since its birth. In recent years, with the continuous progress of installation technology, it has been recognized and applied in various industries. The production and maintenance of LED display outdoor LED floor also requires professional knowledge. How to realize HD display? To realize HD display, there must be four factors: first, the film source requires full HD; Second, the display needs to support full HD; Third, reduce the dot spacing of LED display screen; Fourth, the combination of LED display outdoor LED floor and video processor. At present, led full-color display is also moving towards higher definition display

1. Improving the contrast of LED full-color display outside LED floor is one of the key factors affecting the visual effect. Generally speaking, the higher the contrast, the clearer and more eye-catching the image, and the brighter the color. High contrast helps to improve image clarity, detail performance and gray performance. 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 and integrity. Contrast has a greater impact on the dynamic video display effect. Due to the fast light dark conversion in dynamic images, the higher the contrast, the easier it is for human eyes to distinguish this conversion process. In fact, improving the contrast of LED full-color screen is mainly to improve the brightness of full-color LED display and reduce the surface reflectivity of the screen. However, the higher the brightness, the better. If it is too high, it will be counterproductive, which will not only affect the service life of LED display, but also cause light pollution. High brightness and light pollution have become topics of discussion, which will have an impact on the environment. After special treatment, the LED panel and LED light-emitting tube of full-color LED display screen can reduce the reflectivity of LED panel and improve the contrast of full-color LED display screen

2. Improve the gray level of LED full-color display outdoor LED floor. Gray scale refers to the brightness level that can distinguish the darkest and brightest in the monochrome primary brightness of LED full-color display screen. The higher the gray level of yunhaihui full-color LED display, the richer the color and the brighter the color; On the contrary, the display color is single and the change is simple. The improvement of gray level can greatly improve the color depth and increase the geometric progression of image color display. The gray control level of LED is 14-16 bits, which makes the image level resolution details and display effect 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

3.Reducing the point spacing of LED full-color display outdoor LED floor and reducing the point spacing of LED full-color display can improve its clarity. The smaller the dot spacing of full-color LED display, the finer the picture display. However, this must be supported by mature technology. Its investment cost is relatively large, and the price of full-color LED display is also high. Fortunately, the market is also moving towards small spacing LED displays

4.Development. Led full-color display combined with video processor LED video processor can use advanced algorithms to modify signals with poor image quality, and carry out a series of processing such as de interlacing, edge sharpening and motion compensation, so as to enhance image details and improve image quality. The image scaling processing algorithm of the video processor is used to ensure that the sharpness and gray level of the image are maintained to the greatest extent after scaling processing. In addition, the video processor also requires a wealth of image adjustment options and adjustment effects to process image brightness, contrast and gray, so as to ensure that the screen outputs soft and clear images.
