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.
