Abstract
A projector panel includes pixel display, a display controller, and a pattern generator. The pattern generator is operative to output pixel data indicative of at least one application specific predetermined pattern. In a particular embodiment, the projector panel is a liquid-crystal-on-silicon panel. In another particular embodiment, the projector panel is adapted for selective use in either structured light projection systems or conventional video projection systems.
Claims41
A projector panel comprising:
- a pixel array formed in an integrated circuit, said pixel array including a plurality of pixels arranged in columns and rows;
- a pattern generator formed in said integrated circuit and operative to output pixel data indicative of at least one predetermined pattern, said pattern generator being capable of outputting said pixel data without receiving video data from an external source;
- and
- control circuitry formed in said integrated circuit and operative to assert said pixel data on said pixels of said pixel array to display said predetermined pattern.
A method for manufacturing a projector panel, said method comprising:
- forming a reflective display integrated circuit chip including a plurality of pixels arranged in an array of columns and rows;
- forming a pattern generator in said reflective display integrated circuit chip, said pattern generator being operative to output pixel data indicative of at least one predetermined pattern and being capable of outputting said pixel data without receiving video data from an external source;
- and
- forming control circuitry in said reflective display integrated circuit chip, said control circuitry being operative to assert said pixel data on said pixels of said reflective display.
A non-transitory electronically readable medium having code embodied therein for causing an electronic device to:
- read pixel data corresponding to at least one predetermined pattern from an on-chip pattern generator without receiving video data from an external source;
- and
- assert said pixel data on reflective pixel electrodes of an on-chip display.
