Abstract

The embodiment of the invention provides a pixel circuit, and a driving method and a display device thereof, and relates to a display technical field of displaying. The problem of poor brightness can be solved, and the quality and yield of products are not influenced. A main driving module in the pixel circuit is used for outputting a driving current signal to a fuse module under control of a scanning signal line and a data signal line; the fuse module is used for disconnecting a light emitting module and the main driving module under control of a fuse control module; the fuse control module is used for disconnecting the light emitting module and the main driving module under control of a signal input terminal; a standby driving module is used for outputting the driving current signal to a switching module under control of the scanning signal line and the data signal line; the switching module is used for connecting the standby driving module and the light emitting module under control of a control line input signal; and the light emitting module is used for emitting light through the driving current signal outputted by the main driving module or the standby driving module.

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...
