Abstract
A display panel including a pixel circuit and a light-emitting element, the pixel circuit including a driving transistor, a data writing transistor, a threshold compensation transistor, a first reset transistor, a bias transistor, and a light-emitting control module, the data writing transistor being electrically connected to a first terminal of the driving transistor, the threshold compensation transistor being connected in series between a gate of the driving transistor and a second terminal of the driving transistor, and configured to detect and self-compensate a threshold voltage deviation of the driving transistor, the first reset transistor and the bias transistor being electrically connected to the second terminal of the driving transistor, the light-emitting control module being connected in series with the driving transistor and the light-emitting element to control whether a driving current flows through the light-emitting element, the data writing transistor and the first reset transistor having the same transistor type.
