Abstract:
1. A display system having an area-efficient spatial light modulator, comprising: first array of square pixel elements organized into M element rows and N element columns wherein the first array fits within a first footprint; second array of square electrodes organized into M electrode rows and N electrode columns to activate the array of elements wherein the second array fits within the first footprint; third array of rectangular pixel circuits overlying the array of pixel elements, the array of pixel circuits organized into an array of O rows of pixel circuits and P columns of pixel circuits, the number O being different from the number M and the number P being different from the number N, wherein the numbers N, M, O and P are integers and greater than 2; and a display controller that maps an M rows×N columns data into an O rows×P columns data, and provides the O rows×P columns data to the third array of rectangular pixel circuits, wherein the third array substantially overlies the first footprint, however, the third array of rectangular pixel circuits does not overlie the first array of square pixel elements in a one-to-one correspondence; and every pixel circuit is electrically coupled to a unique pixel element.
