Abstract

This invention provides new control schemes and system configuration to reduce the rainbow effect usually encountered in the field sequential color display systems. By controlling R, G, B color simultaneously using multiple display device systems provide higher quality color display and reducing the rainbow effect. Therefore multiple display device systems have almost same phenomena as the rainbow effect in one frame period. The representative device of this invention is a deformable mirror device that is controlled by the pulse width modulation control or time dividing sequence. The brightness of one color light is determined through total amount of the time of the modulating spatial light modulator elements in one frame. Each color light is modulated for different time period among each color spatial light modulator elements. By modulating different periods among R, G and B color is employed to reduce the false color.
