Abstract

The embodiment of the invention discloses a pixel circuit, a driving method thereof and a display panel. The pixel circuit comprises a driving module used for responding to a data signal to generate adriving current so as to drive a light-emitting element to emit light; a first initialization module controlled by a first scanning signal and a second scanning signal; a first initialization moduleused for initializing the control end of the driving module when the first scanning signal and the second scanning signal are valid; and a data writing module controlled by a third scanning signal. When the second scanning signal and the third scanning signal are valid, the first initialization module is used for cooperating with the data writing module to write the data signal into the control end of the driving module. Compared with the prior art, the embodiment of the invention is beneficial to simplifying the providing mode of the scanning signal on the basis of realizing threshold voltagecompensation, thereby being beneficial to simplifying the structure of the GIP circuit and reducing the frame width of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a pixel circuit, a driving method thereof, and a display panel. Background technique [0002] With the continuous development of display technology, the application range of display panels is becoming wider and wider, and people's requirements for display panels are also getting higher and higher. [0003] The pixel circuit in the display panel plays a very important role in driving the light-emitting element to emit light stably. Specifically, the pixel circuit is used to drive the light-emitting element to emit light under the control of the scanning signal and the light-emitting control signal, and the scanning signal and the light-emitting control signal are provided by a gate driver in Panel (GIP) located in the non-display area of ​​the display panel. . However, existing pixel circuits require a correspondingly configured GIP circuit with a com...
