Abstract

The invention discloses a pixel circuit, a driving method thereof and a display panel. The pixel circuit comprises a resetting module, a data writing-in module, a compensating module, a light emittingcontrol module, a storage capacitor, a driving module, a light emitting component, a photosensitive sensor and a photosensitive sensor control module. All the modules cooperate with one another to achieve a display function and a fingerprint recognition function, and therefore the function of the pixel circuit is added.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel circuit, a driving method thereof and a display panel. Background technique [0002] With the popularization of the Internet and the continuous development of display technology, high-quality display panels have become an important feature of many electronic consumer products. Compared with liquid crystal display panels, organic electroluminescent display panels have self-illumination, low energy consumption, low production cost, wide viewing angle, high contrast ratio, fast response speed, more realistic color display, and are easier to achieve thinner and more flexible. advantage. At present, organic electroluminescent display panels have begun to replace traditional liquid crystal display panels in the display fields of mobile phones, digital cameras, computers, and personal digital assistants, and are expected to become the mainstream choice for next-generation disp...
