Abstract
Disclosed is a device for producing colored light and an image generating apparatus including such a device. The device includes a switchable light-directing apparatus configured to receive light and a first control circuit coupled to the switchable light-directing apparatus. The first control circuit provides control signals to the switchable light-directing apparatus. In response to the switchable light-directing apparatus receiving a control signal, the switchable light-directing apparatus directs a first portion of the received light to a first region of a plane. Additionally, the switchable light-directing apparatus directs a second portion of the received light to a second region of the plane, and directs a third portion of the received light to a third region of the plane. The second region is positioned between the first and third regions of the plane.
