Abstract Color sequential RGB LED driving architecture becomes popular for mobile projectors of which the output are under 10 lumens. One of the difficulties of color sequential projector lies in how to make white balance by mixing RGB color. LED bins and coupling tolerance are diverse so that they have sensitive effects on color temperature distribution. In this paper, the analyses of color temperature distribution and a practical calibration method will be presented.
