Title:
ELECTRONIC DEVICE COMPRISING DISPLAY, AND OPERATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/225253
Kind Code:
A1
Abstract:
An electronic device comprises: a sub-pixel including a first circuit block, a second circuit block, and a light-emitting element; a display panel; a display driving circuit; and a processor, wherein the display driving circuit can store gradation data in a first gate terminal of a first output transistor in the first circuit block, input, into the first gate terminal, a control signal of which the potential varies with time, allow the voltage of a second gate terminal of a second output transistor in the second circuit block to vary in response to the input of the control signal, control a light-emitting time by adjusting an on-state time of the second output transistor, and use a second initialization transistor connected to the second gate terminal to apply an initialization voltage to the second gate terminal two or more times for one frame, and thus perform initialization two or more times.
