Course Instructor

SC1029: DLP Projection Technology

This course explains the principles of displaying images and video using a Digital Micromirror Device (DMD) in UHP lamp and solid-state illuminated systems. The course will begin with giving the audience an overview of colorimetry as it applies to DLP-based systems and the various nuances of a creating a display system based on three to five color primaries. The audience will be given examples of single chip and three-chip systems walking them from electrical signals into the projector to photons out of the projector in both 2D and 3D displays. Examples will include three-chip systems used in DLP Cinema® projectors, color wheel- and lamp-based single chip projectors; LED- and LASER-based single chip projectors used in conventional projectors, televisions and Pico projectors.
