4 tips to improve the clarity of your display
It is not difficult to have a higher LED display screen, just grasp these four factors. Following the computer Monitor for sale China would like to share with us.
Led display has received extensive attention since its birth. With the continuous progress of installation technology in recent years, it has been recognized by various industries and fields. The production and maintenance of led display screen also need professional knowledge, how to achieve hd display? There must be four factors to realize hd display: first, the film source requires full hd; Second, the display requirements can support full hd; Third, to reduce the led display point spacing; Fourth, led display and video processor. At present, LED full-color display screen is also moving towards higher clarity display.
1. Improving the contrast of LED full-color display screen 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 and brighter the color. High contrast is of great help to the definition, detail and gradation of image. In some text with large black and white contrast and video display, high-contrast full-color LED display has advantages in black and white contrast, clarity, integrity and other aspects. Contrast has a greater impact on dynamic video display effect. Since the light and dark conversion in dynamic images is relatively fast, the higher the contrast, the easier it is for human eyes to distinguish such conversion process. In fact, the improvement of the contrast 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 the higher, the better. It is too high. Light pollution has become a hot topic. Too much brightness will affect the environment and people. Full-color LED display LED panel and LED light emitting tube are specially processed, which can reduce the reflectivity of LED panel and improve the contrast of full-color LED display.
2. The grayscale level refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness of the LED full-color screen. On the contrary, the display color is single, the change is simple. The improvement of gray level can greatly enhance the color depth, making the display level of image color increase geometrically. LED grayscale control level is 14bit~16bit, making high-end display products image level resolution of details and display effect have reached the world's advanced level. With the development of hardware technology, LED gray level will continue to develop to a higher control accuracy.
3. Narrow the dot spacing of LED full-color display screen supplied by LED HD screen Touch Monitor supplier. Narrow the dot spacing of LED full-color display screen, which can improve its definition. However, this point, must have mature technology as the core support, its input cost is relatively large, the production of full-color LED display price is also high, but fortunately, the market is now moving towards small spacing LED display development.
4. LED full-color display screen and video processor combined with LED video processor can use advanced algorithms to modify the signal with poor image quality, and perform a series of processing, such as line removal, edge sharpening, motion compensation, etc., to enhance the details of the image and improve the picture quality. Using video processor image scaling algorithm, to ensure that video image after scaling processing, the maximum degree of image clarity and gray level. In addition, video processor is required to have a wealth of image adjustment options and effects, image brightness, contrast, grayscale processing, to ensure that the screen output soft and clear picture.
