Abstract

The embodiment of the invention provides a display panel, a driving method thereof and a display device. The display panel comprises a plurality of pixel circuits and a plurality of light-emitting devices, and one pixel circuit is electrically connected with at least one light-emitting device. The pixel circuit comprises a first driving transistor and a second driving transistor, and the channel width-to-length ratio of the first driving transistor is smaller than that of the second driving transistor; wherein the first driving transistor and the second driving transistor are used for respectively providing driving current for the light-emitting device in different time periods. The problem of display color distortion can be improved, and the display effect is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof, and a display device. Background technique [0002] Mini LED is a micro-sized LED (light-emitting diode), and its chip size is between 50 and 200 μm. Due to the small size of the Mini LED, it is possible to realize an integrated high-density Mini LED array for backlighting or display. [0003] Mini LED displays are generally divided into two types: passive drive and active drive. The passive drive directly inputs current through the driver chip to drive the Mini LED to emit light. The active drive is to design a drive circuit on the panel and use row and column scanning to drive the Mini LED to emit light. Compared with passive drives, active drives can have higher partitions, lower drive costs, support for large sizes, and ultra-thinness. However, when the prior art uses an active driving method for display, there is a prob...
