Abstract
It is possible to replace a standard tuning unit in a television with spatial light modulator circuitry to improve the resolution seen by the viewer. The invention herein provides a system architecture, individual part of the system and techniques for minimizing the burst data rate while maintaining a reasonable system speed. The resultant system provides better resolution with a manageable data rate and bandwidth.
Claims2
An integrated circuit device comprising;
- a. an array of spatial light modulator elements, said elements arranged in rows and said rows grouped into subarrays:
- b. a block select decoder operable to select one of said subarrays;
- and
- c. an input register for receiving data and for transferring said data to said array of spatial light modulator elements, said input register having an output and a means for clearing said output such that all said spatial light modulator elements in said selected subarray may be simultaneously switched to an "off" state.

An integrated circuit device comprising:
- a. an array of spatial light modulator elements, said elements arranged in rows and said rows grouped into subarrays;
- b. a block select decoder operable to select one of said subarrays:
- and
- c. an input register for receiving data and for transferring said data to said array of spatial light modulator elements, wherein said input register is an array of demultiplexers, at least one demultiplexer per subarray, said demultiplexers electrically connected to an array of first-in-first-out buffers, which are in turn electrically connected to a second array of demultiplexers.
