A Novel data line sharing method for high pixel density LCoS microdisplays

A new data line reduction driving method was developed for high pixel density LCoS microdisplays. Its pixel structures and its corresponding gate line waveform were proposed, too. This idea can fulfill the increasing demand for higher resolution LCoS. In this method, no additional AC power is dissipated, and no more horizontal line time is needed. So this method can be applied to the high resolution microdisplay devices. It prefers being applied to the reflective liquid crystal on silicon microdisplays because of the pixel structure asymmetry and PMOS transistor switches used.
