As the main carrier of advertising and information playing, full-color LED display screen is increasingly following the trend of The Times. Hd video can often bring people more shocking visual experience, the content will be more real. To achieve hd display, there must be two factors, one is that the source requires full hd, and the other is that the display requires to support full hd. In fact, the full-color LED display is also moving towards higher clarity. Then, how can we make the full-color LED display more clear? Below, we will make a rough analysis.
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, the clearer and more eye-catching the image is, and the brighter and brighter the color is. 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 full-color LED display is mainly to improve the brightness of full-color LED display and reduce the reflectivity of the screen surface. However, the brightness is not the higher, the better. On the contrary, it will backfire. 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.
Improve the gray level of full-color LED display
Gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness of full-color LED display screen. The higher the gray level of full-color LED display screen is, the richer the color is and the brighter the color is. 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.
Narrow the dot spacing of the full-color LED display
Narrowing the dot spacing of the full-color LED display screen can improve its definition. The smaller the dot spacing of the full-color LED display screen is, the more delicate the screen display will be. 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.
