Generally considered uneven brightness LED single point calibration can be performed to improve the brightness uniformity. And uneven color can not be corrected only by the LED color coordinates segmentation and filtering to improve.

As people increasingly high demand for LED display, LED color coordinates only to be broken down and filtering has been unable to meet the people critical eye, to display a comprehensive correction disposal, so that improved color uniformity are achievable Even the discovery of the first international brand of the same file there is a big LED wavelength deviation and color saturation deviation, and the deviation range greatly exceeds the human eye to green color discrimination threshold. Therefore, chroma uniformity correction is of importance

LED display in all walks of life has a very wide range of applications, and in the different application areas of the LED's color wavelengths have different requirements for LED color wavelength selection is to get some good visual effects, some people in order to comply habits, and some of them are industry standards, national standards and even international standards.

Monochrome Display LED display technology from the early 1980s and the late 1980s two-color display, to the mid-1990s the three primary colors (full color) display until today we have a wide range of areas in the flat panel display Multi-color (more than three primary colors) for technical discussions. LED display color processing technology color wavelength selection from the most basic to the white color temperature of the deployment, and then to improve the color reproduction of the color space conversion is performed to improve the quality of treatment and chroma uniformity of treatment, until Today we have to expand the color gamut to reproduce the natural color and take more multiprimary (more than three primary colors) process. Various color processing technology throughout the history of the development of the LED display, LED electronic display has become one of this comprehensive discipline in the core technology.

For example, for full-color LED display green tube color wavelength selection; earlier it was generally chosen wavelength of 570nm yellow a green LED, although the low cost, but a smaller color gamut of the display, color reproduction is poor, low brightness. And after selecting a wavelength of 525nm pure green tube, display color gamut expanded nearly doubled, and the color reproduction is greatly improved, greatly enhancing the visual display.

White color coordinates the deployment of full-color LED display is one of the most basic technology. But in the mid-1990s, due to the lack of industry standards and basic means test, usually just rely on the human eye, the feel determines the white color coordinates, causing serious cast and-white color temperature of randomness. With the promulgation and complete testing means the industry standard, many manufacturers began to regulate the whole process of color matching. But there are still some manufacturers due to the lack of color theory guidance, often at the expense of some color gradation to deploy hundreds of color coordinates, the overall performance is not improved.

Upgrading and improving LED display color processing technology is the future direction of LED display technology, I believe that before long, LED screen display performance and will get a reply upgrade to a higher level.
