Balanced drive photosensitive pixel and method of operating the same

Abstract From the Canadian patent

A pixel includes am active element interconnected with a group of at least two series connected blocking elements, at a nodal point between the blocking elements. In a preferred embodiment the, capacitances of the individual blocking elements are substantially equal thereby enabling capacitive kick during the addressing of the pixel to be reduced. The invention may be readily adapted to provide both linear and two dimensional pixel arrays adapted to function as display devices and photosensors and, having high accuracy, fast access times and high resolution. A method of operating the pixel using balanced driving signals is also disclosed.
