Pixel circuit, driving method thereof and display panel

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, a data writing module, an auxiliary module, a compensation module, a storage module, a coupling module and a light emitting module, the data writing module is used for writing data voltage into the control end of the driving module through the auxiliary module; the compensation module is connected between the first end and the control end of the driving module and is used for compensating the threshold voltage of the driving module; the coupling module is connected with the compensation module and is used for adjusting the voltage of the control end of the driving module through the compensation module according to the received jump voltage; the storage module is connected with the control end of the driving module, and the driving module is used for providing driving signals for the light-emitting module according to the voltage of the control end and driving the light-emitting module to emit light. According to the pixel circuit provided by the embodiment of the invention, the compensation effect can be improved, and meanwhile, the number of via holes is reduced, so that the layout area of pixels is reduced, and high PPI can be realized.

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, organic light-emitting diode (Organic Light Emitting Diode, OLED) display panels have been widely used in the field of optoelectronic displays due to their excellent characteristics such as self-luminescence, high brightness, and wide viewing angle. [0003] A display panel usually includes a plurality of pixel circuits, wherein the pixel circuits include driving transistors, and the driving transistors generate driving signals to drive the light-emitting elements to emit light for display. In the prior art, a large number of via holes exist in the layout of the pixel circuit, resulting in a large pixel layout area, which is not conducive to achieving high PPI.
