ABSTRACT:
The invention is directed to a solid-state projection device incorporating a light source, modulator, and control circuitry on a single chip. For example, projection device may include several sets of VCSELs, each associated with a set of MEMs mirrors and coupled to a control circuitry. The device may also include various Pyrex layers for sealing and angling layers. The device may further include detectors associated with the light source. These detectors may be useful in determining the shape and location of the projection surface, building a gesture interface, and determining the operability of proxels. The invention is also directed to methods for using the device for manipulating the image, producing zoom, masking, reverse images, positioning, and keystone correction, among others. The invention may be used in projection display devices, portable display devices, heads-up displays, retinal displays, rear and front projection displays, and other display applications.
