AI Technical Summary
Technical Problem
The performance of existing OLED display panels needs to be improved.
Method used
By designing a pixel circuit that includes a driving module, a coupling module, a data writing module, and an initialization module, and by adopting a shared gate driving circuit, the number of gate driving circuits is reduced, the bezel width of the display panel is lowered, and the low-frequency effect and display uniformity are optimized through the cooperation of the compensation module and the initialization module.
Benefits of technology
It achieves a narrow bezel design and improves the performance of the display panel, especially low-frequency flicker and brightness uniformity.

Abstract
Embodiments of the present application disclose a pixel circuit and a display panel. The display panel comprises a pixel circuit and a first gate drive circuit. The pixel circuit comprises a driving module, a coupling module, a data writing module and a first initialization module. The data writing module is electrically connected to a first end of the coupling module, and the data writing module is connected to a data voltage. A second end of the coupling module is electrically connected to the driving module. A first end of the first initialization module is connected to a first initialization voltage, and a second end of the first initialization module is electrically connected to a first end of the driving module. The first gate drive circuit comprises a plurality of cascaded first shift registers. Control ends of the data writing module and the first initialization module in the same pixel circuit are electrically connected to output ends of corresponding first shift registers. The embodiments of the present application are beneficial to the realization of a narrow frame of the display panel.
