  • Abstract
    A 2.6 inch VGA active-matrix LCD has an integrated optical input function. The optical input function may be used for touch input or fingerprint recognition applications and is achieved by integrating image sensor elements within each display pixel. By using a 1-transistor active-pixel sensor, a 30Hz, 300dpi VGA image sensor is integrated within an LCD with an aperture ratio of 40%.
