Abstract
This invention relates a kind of chrominance control circuit of a backlight module having a multi-color light source and a light detection element thereof. A mono-color filter film is installed onto a light incident position of a light detector in a backlight module. The mono-color filter film is used to detect intensity of specific wavelength lights in the white light source of the backlight module to reflect and determine the intensity of the backlight light source that really penetrates the color filter of a liquid crystal panel, so that spectrum characteristics of the light source of the backlight module detected by the light detector is the same as that of the light source passing through the color filter detected by the light detector. A chrominance control circuit is further used to adjust spectrum characteristics of the backlight module light source so that the chrominance variation of the backlight light source emitted and passing through the liquid crystal panel is reduced to a lowest level.
