A novel frame-buffering circuit for liquid crystal on silicon microdisplays

The reduced view time caused by line-at-a-time addressing in field sequential display systems can be mitigated by employing a frame-at-a-time addressing scheme. This drive scheme allows the next image data to be written to the display and buffered in storage while the current frame is being viewed, increasing both system brightness and contrast ratio. We present simulation results and experimental data on frame buffered circuits capable of storing analog data at a pixel, while the previous image frame is being viewed. Employing a global clock at the right time allows a frame at a time to be transferred onto the display
