Pixel circuit, display panel and brightness compensation method thereof

Disclosed are a pixel driving circuit and method, and a display device. The pixel driving circuit includes: the first port of the operation module is electrically connected via the first switch unit to the compensation wire connected to the pixel driving module, the second port of the operation module is electrically connected to the compensation wire through the second switch unit; the first switch unit is configured to transmit the driving data provided by the pixel driving module to the operation module in the self-discharge phase, and the operation module is configured to perform the calculation on the driving data in the self-discharge phase to obtain compensation data; the second switch unit is configured to write the compensation data into the pixel driving module through the compensation wire in the data writing stage.

Pixel driving circuit and method, and display device

The present disclosure provides a display panel. The display panel includes a short circuit protection circuit, a pixel driving circuit, and an organic light-emitting element. The short circuit protection circuit includes a detection circuit electrically connected to the organic light-emitting element, and a control circuit electrically connected to the detection circuit and the pixel driving circuit. The detection circuit is configured to detect whether the organic light-emitting element is short-circuited. The control circuit is configured to control, in response to a detection result of the detection circuit, whether the pixel driving circuit performs driving. In the present disclosure, the display panel includes a plurality of pixel units arranged in rows and columns. This prevents the pixel driving circuit from burning the organic light-emitting element that is short-circuited or other adjacent organic light-emitting element.
