Abstract:
A display device comprises: a display panel including a first display area comprising a first pixels, and a second display area comprising a second pixels, each pixel including a light emitting element; a data driver circuit configured to output data voltages of an image to the first and second pixels; a gate driver configured to output scan signals to the first and second pixels; and a power supply configured to generate a low-potential power supply voltage that is applied to the light emitting element included in each pixel, the low-potential power supply voltage switching between a first level such that the light emitting element is capable of emitting light, and a second level such that the light emitting element cannot emit light, wherein a frame period of the display device includes an addressing period during which the low-potential power supply voltage switches from the second level to the first level.
