Abstract

A display device and a driving method thereof are provided. The display device includes a display panel, a controller, and a driver. The display panel includes a plurality of light-emitting elements. The controller receives characteristic information of the light-emitting elements, and obtains a first relationship curve between current density information and luminous efficiency information according to the characteristic information. The controller obtains a second relationship curve between duty cycle information and accumulated current consumption information or accumulated power consumption information according to the first relationship curve. The controller finds a selected duty cycle corresponding to a maximum luminous efficiency according to the second relationship curve. The driver activates the light-emitting elements according to the selected duty cycle.
