Abstract

The white filed display quality of LED panel is increasingly focused. The white field display quality is mainly the luminance and chromaticity

and the primary luminance of the LED panel is one of the important factors affecting the luminance and chromaticity of the white field. In order to obtain the mathematical relationship between primary luminance and brightness and chromaticity of white field

quantificat the deviation of luminance and chromaticity of the white field caused by primary luminance deviation

according to establish the mapping model of the three primary luminance and the luminance and chromaticity of the white field in the CIE-

Yxy

color space

this paper obtains the spatial model of deviation of the luminance and chromaticity of the white field deviation caused by the brightness variation of red

green and blue primary individually or compounded. The influence on luminance and chromaticity of the white field by the primaries variation has been analyzed in the orthographic plane of the color space model. The mathematical relationship has a general form in CIE-

Yxy

color space

and can quickly determine the deviation of luminance and chromaticity of white field caused by the variation of primary luminance of any LED panel.
