Pixel circuit, driving method of pixel circuit, and display device

Abstract

The embodiment of the invention provides a pixel circuit, a driving method of the pixel circuit, and a display device, relating to the field of display technologies, for solving the problem of poor luminous points, wherein no injuries are caused to the pixel. In the pixel circuit, a drive module is connected with a scanning signal line, a data signal line, a first voltage end and a fusing module, and is used for outputting driving current signals to the fusing module under the control of the scanning signal line and the data signal line; the fusing module is further connected with a fusing control module and a light-emitting module, and is used for breaking the connection of the light-emitting module and the drive module under the control of the fusing control module; the fusing control module is further connected with a control line and a grounding end, and is used for enabling the driving current signals output to the fusing module by the drive module to flow to the grounding end under the control of the input signals of the control line, so that the connection of the light-emitting module and the drive module is broken; the light-emitting module is further connected with a second voltage end, and emits light through the driving current signals output by the drive module under the control of the second voltage end.

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] Organic Light Emitting Diode (OLED) has the advantages of self-illumination, high contrast, wide color gamut, simple manufacturing process, and easy formation of flexible structure. Therefore, the display technology using organic light emitting diode has become a kind of important display technology. [0003] In particular, Active Matrix Organic Light Emitting Diode (AMOLED) has great development potential due to its advantages of no viewing angle limitation, low manufacturing cost, fast response speed, and power saving. [0004] However, due to problems in design and process stability of current OLED display panels, the probability of occurrence of bright spots is very high, and the tolerance of bright spots is almost zero in many applications in many fields. [0005] At pre...
