Abstract: A pixel circuit, a pixel driving method and a display device. The pixel circuit includes a light-emitting element, a driving circuit, a first energy storage circuit, a second energy storage circuit, a data writing circuit, and a compensation control circuit. The data writing circuit controls writing of a data voltage on a data line into a data writing node under control of a scanning signal. The compensation control circuit controls whether a second node is connected with or disconnected from a compensation node under control of a first reset signal. The compensation node is electrically connected to a third node, and/or, the compensation node is electrically connected to a second terminal of the driving circuit. The present disclosure can achieve high-frequency driving under the premise of sufficient compensating for the threshold voltage of the driving transistor included in the driving circuit.

Abstract: A display panel has an opening region, a display region, and first and second peripheral regions; and includes a substrate, a first barrier structure surrounding the display region and in the first peripheral region, a second barrier structure surrounding the opening region and in the second peripheral region, and a crack detection line including first and second portions. The first portion surrounds the opening region, and is on a side of the second barrier structure distal to the display region. Both ends of the second portion are respectively connected to both ends of the first portion. Orthogonal projections of the second portion and the second barrier structure on the substrate overlap each other. The second portion extends into the first peripheral region through the display region. A height of a portion of the second barrier structure overlapping the second portion is less than that of the first barrier structure.
