Abstract: The present invention discloses systems, equipment and methods that allow the improved tiling of multiple projections displays in order to create higher resolution images. Equipment and methods are disclosed for improved blending of the seam by optical means where edge blending masks are employed to create a brightness ramp in the blending region. Equipment and methods are also disclosed for the correction of artifacts in an optically blended seam by modifying the brightness of image pixels in the overlap or blend region. Equipment, systems, and techniques are disclosed for preserving the resolution and uniformity of the image across each seam by actively controlling the position of each display using a servo controlled lens mount for the positioning of each projected image in conjunction with a real time image analysis system.

Abstract: An electronic projector has a projection system that includes a spatial light modulator (SLM) for importing image information to the projected light beam. The light beam leaving the SLM is prepolarized in a defined orientation and the projected light is polarized in the same orientation so as to effectively block any light that has been scattered within the projector and become depolarized. The SLM may be a digital mirror device (DMD). Reflective surfaces within the projector may be covered or coated with material that alters the polarization of reflected stray light from the defined orientation or depolarizes the reflected stray light.
