Abstract: The present disclosure relates to a sensing device and a display device including the sensing device. The sensing device includes a transducer including first and second driving electrodes and a piezoelectric material layer; first and second transmission transistors for alternatively supplying first and second driving voltages to the first driving electrode; and first and second reception transistors electrically connected between a readout line and a power supply line to which a power supply voltage is supplied. During an interval in which at least one pixel is driven, the first and second driving voltages are DC voltages with a voltage level different from each other, and the first and second transmission transistors repeat turn-on and turn-off at a timing different from each other. Through this, it is possible to reduce unnecessary power consumption, and therefore, a large area fingerprint sensor can be more efficiently implemented.

Abstract: An organic light-emitting diode display can include an improved aperture ratio by configuring a circuit pattern between neighboring subpixels in a symmetrical fashion such that the subpixels share signal lines. Each pixel of the organic light-emitting diode display is formed in a symmetrical fashion with respect to one contact area, the number of reference connecting patterns can be reduced and therefore the area occupied by an opening area for each pixel can be made wider, thus leading to an improved aperture ratio.
