Title:
PIXEL CIRCUIT, DISPLAY DEVICE, METHOD FOR DRIVING PIXEL CIRCUIT, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/087950
Kind Code:
A1
Abstract:
There is provided a pixel circuit including: a light-emitting element; a driving transistor whose source is connected to an anode of the light-emitting element; a sampling transistor, whose source is connected to a gate of the driving transistor, that samples a signal voltage to be written to the driving transistor; and a reset transistor that resets the anode of the light-emitting element to a predetermined potential at a predetermined timing. The reset transistor switches from on to off before the signal voltage is written to the driving transistor, switches from off to on while the signal voltage is being written to the driving transistor after the switching, and switches from on to off before a period in which the light-emitting element emits light after the writing.
