  • Patent number: 11451728
    Abstract: An organic photoelectric film on a substrate may perform photoelectric conversion of incident light. Pixel electrodes are arranged in a matrix form in an X-axis direction and a Y-axis direction between the substrate and the organic photoelectric film. A driving circuit may read pixel information from each pixel electrode of a pixel electrode line including a plurality of pixel electrodes arranged in the X-axis direction, and applies an on-voltage or an off-voltage to each pixel electrode 40 of the pixel electrode line. The driving circuit may scan a photoelectric conversion ON region to which the on-voltage is applied in the ?Y-axis direction in synchronization with a timing of scanning a read line to which the pixel information is read in the ?Y-axis direction.
