Patent ID: 8456389

Claim:
A display device comprising: a luminescence element; a power line that provides the luminescence element with an electric current; a capacitor that accumulates a driving voltage corresponding to a data voltage; a driver that flows the electric current according to the driving voltage accumulated in the capacitor through the luminescence element via the power line; and a controller configured to: set a reverse bias voltage and an application time period according to an amount of luminescence produced by the luminescence element; and determine luminance levels in luminescence periods, wherein the controller is configured to set the reverse bias voltage and the application time period according to a peak luminance of the luminance levels when a difference between the peak luminance and an average luminance of the luminance levels exceeds a predetermined threshold, and the controller is configured to apply the reverse bias voltage for the application time period within an OFF period of the data voltage for removing an electric charge accumulated in the luminescence element, the OFF period being within one of the luminescence periods.
