Title:
PIXEL DRIVING CIRCUIT AND PIXEL DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/082122
Kind Code:
A1
Abstract:
A pixel driving circuit and a pixel driving method. The pixel driving circuit comprises a first transistor, a second transistor, a third transistor, a fourth transistor, and an organic light emitting diode. When a first scanning signal is at a high level, the second transistor transmits a data signal level to a gate of the first transistor. When the second scanning signal is at a high level, the fourth transistor transmits the data signal level to a gate of the second transistor. A driving current flows through the organic light emitting diode to enable the organic light emitting diode to emit light. The problem of threshold voltage shifts of the transistor during high-brightness display can be improved.
