Abstract

The invention discloses a driving circuit, a driving method thereof and a display panel, and belongs to the technical field of display. The driving circuit at least comprises a pixel circuit and a multi-path selection circuit; the pixel circuit at least comprises a driving transistor, a light-emitting device and a data write-in module. The driving transistor is connected in series between the first power supply signal end and the light-emitting device to generate driving current; the data write-in module is connected in series between the driving transistor and the multi-path selection circuit and is used for providing a data signal for the driving transistor; the output end of the multi-path selection circuit is connected with the input end of the data writing module through a data line, and the multi-path selection circuit is used for writing a data signal into the data line while the driving transistor performs threshold compensation. The driving method is used for driving the driving circuit. The display panel at least comprises the driving circuit. While the display effect is ensured, the bezel narrowing of the display panel is facilitated.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a driving circuit, a driving method thereof, and a display panel. Background technique [0002] Organic Light Emitting Diode (OLED) is one of the hotspots in the field of flat panel display research. Compared with liquid crystal displays, OLED has the advantages of low energy consumption, low production cost, self-illumination, wide viewing angle and fast response speed. Currently, OLED has begun to replace traditional liquid crystal displays ( Liquid Crystal Display, LCD). Among them, the design of the driving circuit is the key technology to realize the display function. Driving circuits generally include scanning driving circuits, light emission control circuits, data driving circuits, pixel circuits, etc. Among them, pixel circuit design is the core technical content of OLED displays and has important research significance. [0003] With the development o...
