ABSTRACT:
A half-tone pixel having subpixels and control capacitor constituting a 100 percent optically active pixel. The subpixel design results in no reductions in the maximum pixel aperture ratio, brightness or contrast, as a pixel with no subpixels would have. Various subpixel layouts including differing numbers of subpixels and subpixel-turn-on sequences may be implemented and still result in the entire pixel being optically active.
