A programmable driving circuit for multi-quantum-well spatial-light-modulator

摘要

A universal programmable driving circuit of multi-quantum-well spatial light modulator was described. The driving circuit, by double scanning and employing a new current-switching network, reduces the pixel’s estate and improves the output resolution. The results of test by chip show that the driving voltage could swing from 0 to V _DD, and its resolution could reach to 256 with only 65 × 65 μm pixel estate.
