Abstract

The present disclosure relates to a pixel circuit, its driving method, and a display device. The pixel circuit includes: a driving subcircuit, a data writing subcircuit, a compensation subcircuit, a light emission control subcircuit, a first energy storage subcircuit and a second energy storage subcircuit. The energy storage subcircuit; the driving subcircuit is respectively connected to the first power supply terminal, the first node and the second node; the data writing subcircuit is used to transmit the data signal to the first node in response to the first scanning signal; the compensation subcircuit The circuit is used to transmit the first power signal to the first node in response to the compensation control signal; the light emission control subcircuit is used to transmit the signal of the second node to the first end of the light emitting element in response to the light emission control signal The first energy storage subcircuit is connected between the first node and the second node; the second energy storage subcircuit is connected between the first power supply terminal and the second node.

Description

Technical field[0001]The present disclosure relates to the field of display, and in particular, to a pixel circuit and a driving method thereof, a display device.Background technique[0002]With the development and progress of technology, the use of OLED display devices is gradually wide. The OLED display device is typically illuminated by the pixel circuit driving the light-emitting element, and the pixel circuit generates a drive current by driving the transistor.[0003]During the production of the display device, due to the impact of the production techniques and the process, the parameters of all drive transistors cannot be guaranteed, thereby causing different technical parameters of different driving transistors, such as threshold voltage and mobility. Since the threshold voltage drift is different, the current of the different transistors is different, thereby causing unevenness of the brightness of each light-emitting element, affecting the display effect.[0004]It should be not...
