Abstract

The invention discloses a pixel circuit, a drive method therefor, an array substrate and a display device, and belongs to the technical field of display. The pixel circuit includes a drive module anda switch module, wherein the switch module is connected in series with a drive transistor in the drive module, and the switch module and the drive transistor in series connection are respectively connected with a power signal line and a light emitting unit. The drive module is also respectively connected with a gate line and a data line, and is used for providing a power signal from the power signal line for the light emitting unit through the drive transistor under the control of a gate drive signal provided by the gate line and a data signal provided by the data line. The switch module is also connected with a switching signal line, for controls the connection and disconnection between the power signal line and the light emitting unit under the control of a switching signal provided by the switching signal line. The pixel circuit provided by the invention can avoid dynamic smear when the display device displays a dynamic image, and the display device has a better display effect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel circuit and a driving method thereof, an array substrate and a display device. Background technique [0002] The pixel circuit is a circuit for driving OLED to emit light in an organic light emitting diode (Organic Light Emitting Diode, OLED) display device. [0003] In the related art, a pixel circuit generally includes a plurality of transistors and at least one capacitor. Among the plurality of transistors, there is a driving transistor, which can be used to control the magnitude of the current flowing through the OLED, thereby controlling the luminance of the OLED. The capacitor is connected to the gate of the driving transistor, and is used to maintain the gate voltage of the driving transistor, so that the driving transistor remains in an on state within one frame time, thereby ensuring that the OLED continues to emit light. [0004] However, when the disp...
