A display panel includes a driver circuit including shift registers with N stages and being cascade with each other, where N≥2, and each shift register includes a first control portion and a second control portion. The first control portion is configured to control a first output signal, where the first output signal of an i-th stage of shift register is an input signal of a j-th stage of shift register, and 1≤i≤N, 1≤j≤N. The second control portion is configured to receive at least the first output signal and a frequency control signal and control a second output signal. In a case where the first output signal is an effective pulse and a time period of the effective pulse is within a time period of an effective pulse of the frequency control signal, the second output signal is the effective pulse.

Display panel and display device

A display panel includes a pixel circuit and a light-emitting element. The working process of the pixel circuit includes a data write stage and a bias stage. The working process of the pixel circuit includes a first light emission stage and a first non-light emission stage. In the first non-light emission stage, a bias maintaining stage is from the start moment of the bias stage to the start moment of the first light emission stage. Working modes of the display panel include a first mode and a second mode. The display brightness of the display panel in the first mode is different from the display brightness of the display panel in the second mode. The length of the bias maintaining stage in the first mode is different from the length of the bias maintaining stage in the second mode.

Display panel and device with bias maintaining stage duration according to brightness

Provided are a display panel and a display device. The display panel includes a substrate and a drive circuit disposed on one side of the substrate. The drive circuit includes a first transistor. The first transistor includes a first active layer. The first active layer includes an oxide semiconductor. The drive circuit also includes a first capacitor. One capacitor plate of the first capacitor is disposed in the same layer as the first active layer. In the display panel according to embodiments of the present disclosure, a substrate of a first capacitor in a drive circuit is disposed in the same layer as an active layer of an oxide semiconductor.
