Pixel circuit with shared active regions

摘要

An LCD pixel device is provided of the type deployed in a matrix of pixels selectively energized by a plurality of row lines and plurality of column lines and wherein a video voltage is stored on at least one pixel capacitor and coupled to an image-generating device. First and second source regions are formed near the surface of a semiconductor substrate. A drain region is likewise formed in the substrate between the first and second source regions forming the channels of first and second field-effect-transistors. An insulating layer is formed on the substrate, and first and second gate electrodes are provided in the insulating layer between the first source region and the drain region and the second source region and the drain region respectively. First and second mirrors are provided on the surface of the insulating layer. Conductive interconnects formed in the insulating layer provide electrical coupling between the first and second transistors, the first and second capacitors, and the first and second mirrors, respectively.
