Title:
DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/124165
Kind Code:
A1
Abstract:
[Problem] To improve brightness. [Solution] This display device is provided with a pixel array unit in which a pixel circuit is arranged, and a drive circuit for driving the pixel array unit, wherein the pixel circuit includes: a light emitting element which emits light having a brightness corresponding to a current flowing from an anode to a cathode; a drive transistor for driving the light emitting element on the basis of a written signal voltage; a sampling transistor for sampling the signal voltage written to the drive transistor; and an anode voltage control unit for making the anode voltage of the light emitting element higher than the cathode voltage of the light emitting element during a signal voltage writing period in which the sampling transistor is turned on and the signal voltage is written to the drive transistor.
