How can I make my LED rental screen more HD?

  With the continuous development of the times, people for the LED rental screen screen display effect requirements have become more and more high, after all, high-definition video images to bring people the shock effect is very strong, the content displayed relative to the traditional video images are more attractive, better to meet the people on the pursuit of high-quality audio-visual beauty. So do you know how to makeLED rental screenBecome more HD? The following is a small introduction from VisiTech:

  To make the LED rental screen become more high-definition, you need to do the following aspects:

  1, improve the contrast of the LED rental screen.

  Contrast is one of the key factors affecting the visual effect, generally speaking, the higher the contrast, the clearer and more eye-catching the image, the more vivid and colorful. High contrast for image clarity, detail performance, gray level performance are very helpful. In some black and white contrast text, video display, high contrast LED rental screen in black and white contrast, clarity, integrity and other aspects have advantages. Contrast for dynamic video display effect to have a greater impact, due to the dynamic image of light and dark conversion is relatively fast, the higher the contrast, the easier it is for the human eye to distinguish such a conversion process.

  In fact, the contrast of LED rental screen to improve the brightness of the LED rental screen and reduce the surface reflectivity of the screen, however, the brightness is not the higher the better, too high, on the contrary, it will be counterproductive, not only will affect the life of the LED rental screen, but also cause light pollution. Light pollution has become a hot topic now, too much brightness will have an impact on the environment and the crowd. LED rental screen LED panel and LED light-emitting diodes for special processing, can reduce the reflectivity of the LED panel, but also can improve the contrast of the LED rental screen.

  2, improve the LED rental screen gray level.

  Gray level refers to the LED rental screen single-color brightness from dark to bright between the brightness level can be distinguished, the higher the gray level of the LED rental screen, the richer the color, the more colorful; Conversely, the display of a single color, the change is simple. Gray scale level increase, can greatly enhance the color depth, make the image color display level is geometric increase. LED gray scale control level of 14bit ~ 16bit, make the high-end display products of the image level resolution details and display effect have reached the world's advanced level. With the development of hardware technology, LED grayscale level will continue to higher precision control development.

  3, reduce the point spacing of the LED rental screen.

  Reduce the point spacing of the LED rental screen, can be very good to improve its clarity, the smaller the point spacing of the LED rental screen, the more delicate its picture display. However, this point, there must be mature technology as the core support, its input cost is relatively large, the production of LED rental screen price is also high, but fortunately now the market is also moving towards the development of small pitch LED rental screen.

  4, LED rental screen and video processor combination

  LED video processor can use advanced algorithms to image poor quality signal modification, the implementation of de-interlacing, edge sharpening, motion compensation and so on a series of processing, to enhance the details of the image to improve the quality of the screen. The use of video processor image scaling processing algorithms to ensure that the video image after scaling, the maximum degree of clarity and gray level of the image to maintain. In addition, the video processor is also required to have a wealth of image adjustment options and adjustment effects on the image brightness, contrast, grayscale processing to ensure that the LED screen output soft and clear picture.

  In summary, we can see that we want to make the LED rental screen become more high-definition, you need to improve the contrast of the LED rental screen, improve the LED rental screen gray level, reduce the LED rental screen point spacing, as well as the realization of the LED rental screen and the video processor combination of the four aspects, we can only do these aspects of the LED rental screen to become more high-definition, to us to create a stronger visual effect.
