Abstract

A pixel circuit, a method for driving a pixel circuit and a display panel are provided. The pixel circuit includes a control sub-circuit, a shunt sub-circuit, a light emitting sub-circuit and a latch sub-circuit, where the control sub-circuit is configured to output to the latch sub-circuit a data signal from a data signal line in response to a scan signal from a scan signal line; the latch sub-circuit is configured to latch a first level signal and a second level signal in response to the data signal and the scan signal, and output the second level signal to light emitting sub-circuit in response to a switch signal from a switch signal line, to enable the light emitting sub-circuit to emit light; and the shunt sub-circuit is configured to shunt, in response to a control signal from a control signal line, the second level signal input to the light emitting sub-circuit, to adjust a light emitting brightness of the light emitting sub-circuit.

Description

technical field [0001] The invention relates to the field of display technology. More specifically, it relates to a pixel circuit, its driving method and a display panel. Background technique [0002] In the existing gray-scale static latch module, the latch module responds to the data signal of the data signal line to latch the low level and high level, and in the light-emitting stage, the gray-scale display of the light-emitting diode is controlled by the switching signal of the switch signal line . However, in the pixel circuit of the current OLED display panel, the light-emitting diode can only be turned on and off through the switch signal line to realize simple gray-scale display, but multi-gray-scale display cannot be realized. [0003] Therefore, it is necessary to provide a pixel circuit capable of multi-grayscale display, its driving method and a display panel. Contents of the invention [0004] An object of the present invention is to provide a pixel circuit ...
