Abstract
Several embodiments of display systems are disclosed that comprise a backlight source, a first modulator, a second modulator and a controller. The backlight source may further comprise an edge-lit backlighting source that may be controlled to affect a field-sequential illumination for the dual or multiple modulator display system. In another embodiment, the display system may comprise two or more color primary emitters that each comprise a color gamut. When the color gamuts are driven in a field sequential pattern, the resulting overall gamut is substantially wider. Other display systems and methods are disclosed herein that affect a variety of 3D viewing embodiments. Systems, methods and techniques to increase the dynamic range, color gamut and bit precision of display systems comprising MEMS and/or IMODs are presented.
