Abstract
A single-plate modulation panel comprises, for each pixel, a drive signal storage section for storing the drive signals corresponding to three colors used during the individual modulation of three-color illumination light; a color selection section for selecting one of the drive signals for the three colors stored in the drive signal storage section; and a modulation-executing section for performing modulation in accordance with the drive signals selected by the color selection section. Three light sources are controlled such that the single-plate modulation panel is illuminated with three-color illumination light in a recurring fashion one color at a time. In addition, the color selection section is controlled such that one of the drive signals corresponding to the three colors stored in the drive signal storage section is applied to the modulation-executing section while being switched in synchronism with the lighting timing of three-color illumination light.
