Abstract

The invention discloses a pixel circuit, a display panel and a display device, in order to improve the problem that the display panel in the prior art can only correspond to one video source after the production is completed, resulting in poor design flexibility. An embodiment of the present invention provides a pixel circuit, including: a first switching transistor, a second switching transistor, a driving transistor, a capacitor, a light emitting diode, a first gate line extending along a first direction and a first data line extending along a second direction The extended second gate line, the second data line, and the power line, the first direction and the second direction cross each other; the gate of the first switching transistor is coupled to the first gate line, and the The source of the first switch transistor is coupled to the first data line; the gate of the second switch transistor is coupled to the second gate line, and the source of the second switch transistor is coupled to the second data line coupling.

Description

technical field [0001] The present invention relates to the technical field of semiconductors, in particular to a pixel circuit, a display panel and a display device. Background technique [0002] Flat panel display (F1at Pane1 Display, FPD) has become the mainstream product in the market, and there are more and more types of flat panel displays, such as liquid crystal display (Liquid Crystal Display, LCD), organic light emitting diode (Organic Light Emitted Diode, OLED) display , Plasma Display Panel (P1asma DisplayPane1, PDP) and Field Emission Display (Field Emission Display, FED), etc. [0003] At present, the mainstream display panels are mostly rectangular, mainly divided into two types: portrait (Portrait) and landscape (Landscape). After the product is produced, it needs to correspond to video sources with different resolutions, and it cannot be switched again. Freedom of production design Poor flexibility. Contents of the invention [0004] The present invention...
