  • Publication number: 20140375622
    Abstract: A scanning order calculating portion (23) included in a display control circuit (200) determines the order of selecting all rows by repeating the following: the row for which the total amount of potential variation relative to a reference row is the lowest is selected as a subsequent row, and the row having been selected as the subsequent row is used as the next reference row in a similar operation to determine the next row to be set as a subsequent row. A scanning order setting portion (24) controls an address outputting portion (26) such that the scanning signal lines are selected in the determined order, and also controls digital image signals DV outputted by output frame memory (22). Power consumed by driving video signal lines can be reduced by selecting the scanning signal lines in such an order that the total amount of potential variation of the video signal lines becomes smaller.

  • Publication number: 20130162602
    Abstract: A plurality of sensor circuits each including an optical sensor and a charge retention transistor each provided between a reset line and an accumulation node are arranged in a pixel region of a display device. In a sensing period, a LOW-level voltage is applied as a reset cancellation voltage to the reset line RSTa, and a HIGH-level voltage is applied to a control line CLKa to control the charge retention transistor to be in an ON state. In a period other than the sensing period, the LOW-level voltage is applied to the control line CLKa to control the charge retention transistor to be in an OFF state, and the HIGH-level voltage is applied as a retention voltage to the reset line RSTa. Thus, a drain-source voltage Vds of the charge retention transistor is lowered, a leakage current through the charge retention transistor is reduced, and a light detection accuracy is enhanced.
