White Balance Color Correction Based on Micro LED Display Panel

This study aims at the development of color correction for white balance on the Micro LED display panel. White balance must be kept under various luminance. However, the fixed method LED cannot achieve this requirement. First, we estimate the level of luminance Y for the current image, from RGB color conversion. The adaptive method is presented to modify the RGB level according to the Y signal. The adaptive parameters with $\alpha$ and $\beta$ value are employed to adjust the magnification value and DC level respectively. Before color correction, the micro LED displays blue in high brightness, and to be red in low brightness. By using the adaptive method, the red level increases in high brightness, and decreases in low brightness, to achieve color balance. Experiments show that the white balance as been completed under various white paper luminance testing. The most white light is excellent on Micro LED in human vision.
