Patent ID: 7161570

Claim:
A method for driving a liquid crystal microdisplay comprising the steps of: coupling at least one channel from a first display driver integrated circuit to the liquid crystal microdisplay; coupling at least one channel from a second display driver integrated circuit to the liquid crystal microdisplay; comparing a frame synchronization signal from said first and second display driver integrated circuits; initiating a transfer of video information through said at least one channel of said first and second display driver integrated circuits to the liquid crystal microdisplay when said frame synchronization signals indicate said first and second display driver integrated circuits are both prepared to transfer video information together to the liquid crystal microdisplay; comparing a frame polarity signal from said first and second display driver integrated circuits; preventing said transfer of video information to the liquid crystal microdisplay if a polarity of said video information provided by said first display driver integrated circuit differs from a polarity of said video information provided by said second display driver integrated circuit; and correcting said polarity difference of said video information between said first and second display driver integrated circuits.
