 Variation of LED Display Color Affected by Chromaticity and Luminance of LED Display Primary ColorsXinyue Mao, Xifeng Zheng, Ruiguang Wang, Hongbin Cheng and Yu Chen Mathematical Problems in Engineering, 2020, vol. 2020, 1-14 Abstract: In recent years, the effect of LED display is increasingly important in the LED display field. Primary colors’ chromaticity and luminance of LED display as crucial elements influence the LED display color. Therefore, there is a need for color mapping algorithms that indicate the relationship between primary colors and display color’s chromaticity and luminance. In this paper, two mathematical models have been developed. One has shown the display color’s chromaticity and luminance affected by luminance of primary colors change. The other one has shown a complicated relationship that primary color is mixed by other primary colors to change chromaticity first and then the mixed primary is used as “new LED primary color.†In both mathematical models, CIE x y Y color space was used as the mutual color space; thus, there was a specific variation tendency of colors with luminance or chromaticity of primary colors change in this color space. The newly designed mathematical models can consistently guide us how to acquire the desired display color by changing luminance or chromaticity of primary colors. Therefore, it has important engineering application value.
