Abstract

The invention discloses a pixel circuit. The pixel circuit comprises a first transistor, a second transistor, a third transistor, a storage capacitor and a light-emitting element. The pixel circuit further comprises a compensation control unit, and the compensation control unit is connected with a first electrode of the first transistor and a sensing line; the compensation control unit is used foraccessing a third scanning signal and realizing auxiliary completion of external compensation and internal compensation of the pixel circuit according to the third scanning signal. The invention further discloses a control method of the pixel circuit, a display substrate and a display device. For the pixel circuit, the control method of the pixel circuit, the display substrate and the display device provided by the invention, the external compensation can be completed, the internal compensation also can be completed, and the display effect can be well improved through the internal and external compensation.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel circuit and a control method thereof, a display substrate, and a display device. Background technique [0002] OLED (organic light emitting diode, organic light emitting diode) display device is a display device that uses organic light-emitting materials to undergo carrier injection and recombination under the drive of an electric field to emit light. It has self-illumination, wide viewing angle, high contrast, and low power consumption. Electricity, high response speed and other advantages. [0003] Currently, there are two commonly used compensation methods for OLED displays: internal compensation and external compensation. [0004] But, the inventor of the present invention finds that there are at least the following problems in the prior art in the process of realizing the present invention: [0005] The internal compensation mainly realizes Vth (threshold ...
