Full color LED display to enhance the definition of the method

Full-color LED display to enhance the definition of daquan, to achieve high-definition display must have four factors: one is the source requirements of full hd;Second, the display requirements can support full hd;Three is to reduce the LED screen point spacing;Fourth, LED display and video processor combined.LED full-color displays are also moving toward higher-definition displays.

1. Improve the contrast of LED full-color display screen

Contrast is one of the key factors affecting the visual effect. Generally speaking, the higher the contrast, the clearer the image and the brighter the color.High contrast is very helpful for image definition, detail expression and gray level expression.In some text and video display with large black and white contrast, high-contrast full-color LED display screen has advantages in black and white contrast, clarity, integrity and other aspects.The contrast has a greater impact on the dynamic video display effect. Because the light and dark conversion in the dynamic image is relatively fast, the higher the contrast, the easier it is for the human eye to distinguish such a conversion process.

In fact, the improvement of the contrast of LED full-color screen is mainly to improve the brightness of full-color LED screen and reduce the reflectivity of the screen surface. However, brightness is not the higher the better, but too high, it will backfire, not only affect the life of LED screen, but also cause light pollution.Light pollution has become a hot topic nowadays. Too high brightness will have an impact on the environment and the population.Full-color LED display special processing of LED panel and LED light emitting tube can reduce the reflectivity of LED panel and improve the contrast of full-color LED display.

2. Improve the gray level of LED full-color display screen

Gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the single-color brightness of LED full-color screen. The higher the gray level of full-color LED screen, the richer the color and the brighter the color.Instead, the display color is simple and the change is simple.The improvement of gray level can greatly enhance the color depth, so that the display level of image color is geometrically increased.LED grayscale control level is 14bit~16bit, which makes the image level resolution details and display effects of high-end display products reach the world‘s advanced level.With the development of hardware technology, LED gray level will continue to develop to higher control accuracy.

3. Reduce the point spacing of LED full-color display screen

Reducing the point spacing of full-color LED screen can greatly improve its clarity. The smaller the point spacing of full-color LED screen, 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 price of full-color LED display produced is also high, but fortunately now the market is also moving towards small spacing LED display development.

4. LED full-color display combined with video processor

LED video processor can use advanced algorithms to modify the signal with poor image quality, perform a series of processing such as deinterlace, edge sharpening, motion compensation, etc. to enhance the details of the image and improve the picture quality.

Video processor image scaling processing algorithm is used to ensure that video image after scaling processing, to maintain the maximum degree of clarity and gray level of the image.In addition, video processor is also required to have a wealth of image adjustment options and effects to process the brightness, contrast and gray of the image to ensure the soft and clear screen output.
