Title:
DISPLAY DEVICE AND METHOD FOR DRIVING SAME
Document Type and Number:
WIPO Patent Application WO/2019/207782
Kind Code:
A1
Abstract:
A pixel circuit of a display device includes: an electro-optical element; a drive transistor; a first transistor, in which a first electrical continuity terminal is connected to the anode terminal of the electro-optical element, an initialization voltage is applied to a second electrical continuity terminal, and the gate terminal is connected to a scan line; a second transistor, in which a first electrical continuity terminal is connected to the gate terminal of the drive transistor, and the gate terminal is connected to an immediately preceding scan line that is selected in one previous horizontal period before the scan line; and a third transistor, in which an initialization voltage is applied to the drain and gate terminals, and the source terminal is connected to the second electrical continuity terminal of the second transistor, the third transistor being connected to a diode. There is thereby provided a display device with which it is possible to suppress both of a bright spot and a misadjusted black level.
