A Novel Pixel structure suitable for color scanner embedded TFT-LCD

  • Published : 2007.08.27


We developed a 4 inch (qVGA, 320x240) a-Si TFT LCD which has the function of color scanner. We have designed the novel pixel structure and got good scanning quality with minimum aperture loss. In this new pixel, the sensor capacitance was increased in double without decreasing the aperture loss.
