Abstract:
The present disclosure relates to display device, display panel, and display driving method. Disclosed herein is a display device including a display panel in which a light emitting element, a driving transistor configured to provide a driving current to a light emitting element using a driving voltage, and a plurality of switching transistors configured to control driving of the driving transistor are disposed; a gate driving circuit configured to supply a plurality of scan signals to the display panel through a plurality of gate lines; an emission driving circuit configured to supply a plurality of emission signals to the display panel through a plurality of emission signal lines; a data driving circuit configured to supply a data voltage to the display panel; and a timing controller configured to, in a low speed mode in which the display panel is operated at a low driving frequency, control the driving current to be applied to the driving transistor during a first emission control period after a bias voltage is applied to the driving transistor, and control the driving current to be applied to the light emitting element through the driving transistor during a second emission control period.
