Abstract

See full text

A display apparatus and a method for driving the same are provided. The display apparatus includes pixel circuits and a threshold detection module. The pixel circuit includes a driving transistor and a data voltage writing module including an output terminal electrically connected to the driving transistor. The threshold detection module is configured to detect a threshold voltage of the driving transistor. An operating process of the pixel circuit includes a first phase and a second phase. The first phase includes a data writing phase and a light-emitting phase. The second phase includes an adjusting phase and a light-emitting phase. The driving transistor receives a data voltage during the data writing phase. During the adjusting phase, the driving transistor receives an adjusting voltage corresponding to the threshold voltage of the driving transistor that is detected by the threshold detection module.
