Abstract

The embodiment of the invention provides a pixel circuit, a drive method therefor, and a display device, and relates to the technical field. The circuit can prevent a part with a camera function from occupying a non-display region of a display device. The pixel circuit comprises a display drive unit, and the display drive unit comprises a resetting module which carries out the resetting of a drive module. The pixel circuit also comprises a write-in module which writes the voltage data in the drive module; a compensation module which is connected with the drive module and carries out the threshold voltage compensation of the drive module; a light-emitting control module which enables the drive module and a light-emitting device to be electrically connected, and provides a drive current for the light-emitting device through a drive module; and the light-emitting device which emits light according to the drive current. The pixel circuit also comprises a detection unit, and a part of transistors in the detection unit and a part of transistors in the display drive unit can be shared. The detection unit collects the incident light, and outputs a collection result to a reading signal line. The pixel circuit is used for display and photographing.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel circuit, a driving method thereof, and a display device. Background technique [0002] With the rapid progress of display technology, semiconductor element technology, which is the core of the display device, has also been greatly improved. For existing display devices, AMOLED (Active Matrix Driving Organic Light Emitting Diode, Active Matrix Driving Organic Light Emitting Diode) display devices have low manufacturing cost, high response speed, power saving, DC drive for portable devices, operating temperature Due to advantages such as large range, it is expected to become the next generation of new flat-panel displays replacing LCD (liquid crystal display, liquid crystal display). [0003] On this basis, in order to realize the camera function in the AMOLED display device, the manufacturer of the display device needs to separately purchase components with the c...
