Title:
PIXEL CIRCUIT, PIXEL DRIVE METHOD AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/228202
Kind Code:
A1
Abstract:
Provided are a pixel circuit, a pixel drive method and a display apparatus. The pixel circuit comprises a drive transistor, a threshold compensation sub-circuit, and a light-emission control sub-circuit. The threshold compensation sub-circuit is configured to write, in a reset phase and under the control of a first control signal end, a second control signal end and a third control signal end, a reset voltage into a control electrode of the drive transistor, and to write, in a data-writing phase, a control voltage into the control electrode of the drive transistor. The driving transistor is configured to generate, in a light-emitting phase, a drive current according to the control voltage. The light-emission control sub-circuit is configured to output, in the light-emitting phase and under the control of a light-emission control signal end, the drive current to a light-emitting device so as to drive the emission of light by the light-emitting device.
