Abstract: Disclosed are a display panel and a display device. The display panel includes multiple sub-pixels disposed on a side of a base substrate and multiple first electrode connecting pieces and second electrode connecting pieces. Each sub-pixel includes a pixel driving circuit and an LED element. At least part of adjacent rows of sub-pixels are provided with multiple spare LED element setting regions, the spare LED element setting regions being disposed on at least one side of each row of sub-pixels, and/or at least part of adjacent columns of sub-pixels are provided with the multiple spare LED element setting regions, the spare LED element setting regions being disposed on at least one side of each column of sub-pixels. Two adjacent sub-pixels on two sides of a spare LED element setting region are respectively a first sub-pixel and a second sub-pixel. The first electrode connecting piece electrically connected to the first sub-pixel and the first electrode connecting piece electrically connected to the second sub-pixel both extend to the spare LED element setting region between the first sub-pixel and the second sub-pixel and are insulated from each other. The spare LED element setting region is further provided with a spare second electrode connecting piece.

Abstract: Disclosed are a pixel driver circuit, a display panel, a display device, and a driving method. The pixel driver circuit includes a data write module, a storage module, a first potential adjustment module, a second potential adjustment module, a comparison module, and a light emission control module. The data write module is configured to write a data signal into a first node at a first stage. The first potential adjustment module and the second potential adjustment module are configured to adjust a potential of a second node at a second stage and at a third stage, causing the comparison module to output a first control signal and a second control signal to the light emission control module at the second stage and at the third stage, respectively. The light emission control module is configured to control the light emission control module to be turned off and turned on according to the first control signal and the second control signal, respectively.
