Abstract: A display apparatus includes a first pixel, a second pixel, and a dummy pixel. The first pixel includes a first light-emitting device connected to a first pixel circuit through a first node. The second pixel is in a same row as the first pixel and includes a second light-emitting device connected to a second pixel circuit through a second node. The dummy pixel includes at dummy pixel circuit with a third node. The controller outputs a first control signal having a first level or a second level based on a first pixel grayscale value corresponding to the first pixel and a second pixel grayscale value corresponding to the second pixel. A switch circuit electrically connects the first node, the second node, and a third node when the first control signal has the first level.

Abstract: A display apparatus includes a display panel, a gate driver, a data driver and an emission driver. The display panel includes a pixel. The gate driver provides a gate signal to the pixel. The data driver provides a data voltage to the pixel. The emission driver provides an emission signal to the pixel. The pixel includes a light emitting element, a driving switching element which applies a driving current to the light emitting element, a storage capacitor connected to a control electrode of the driving switching element and a bias capacitor including a first electrode connected to the storage capacitor and a second electrode which receives a bias gate signal. A waveform of the bias gate signal varies based on an off ratio representing a ratio of an off period of the emission signal in a frame period.
