LCOS micro-display driver integrated circuit

Abstract

Embodiments of the invention provide a driver device for delivery of pixel values in a digitally encoded (PWM) fashion to a LCOS imager, such as a 2-megal pixel imager. In particular, modulated pixel values may be delivered to a LCOS imager. Driver device functions as a high definition imager driver and transmits a PWM pixel stream through interface to imager. Pixel input stream may be received by low I/O buffer which may be implemented as a voltage differential signaling (LVDS) I/O buffer. The data may then be processed at input block, and restored into frame buffer banks. Through pixel lookup tables, the frame data gets transformed into a PWM pulse train and shifted off driver device onto an imager. Frame buffer to signal generator interface may include multiplexers for reordering bits before signal generation.
