Abstract
An electroluminescence display device includes a controller which generates signals for controlling at least one pixel circuit during a first period and a second period. The controller controls current to a light-emitting element of the at least one pixel circuit based on a data voltage in the first period. The controller controls a supplying period of current to the light-emitting element based on a duty control voltage in the second period. The supplying period when the pixel circuit is driven at a first gray scale value is longer than that when the pixel circuit is driven at a second gray scale. The first gray scale value is greater than the second gray scale value.
