摘要： A display device includes an acquiring circuit, a calculator, and a delay controller. The acquiring circuit acquires a gray scale voltage of a gray scale value of a pixel. The calculator calculates a first delay correction value based on a voltage currently retained on a data signal line to which the gray scale voltage is output and a gray scale voltage to be subsequently output to the data signal line. The delay controller determines a timing when the gray scale voltage is to be output to the data signal line based on the first delay correction value.

摘要： 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.

The first transistor is electrically connected between a power supply and a light-emitting element, has a gate to receive a gray scale voltage, and supplies the light-emitting element with a driving current corresponding to the gray scale voltage.

The control circuit reads a measurement value of the voltmeter when the gate of the first transistor receives the gray scale voltage, and corrects a next gray scale voltage applied to the gate of the first transistor based on the measurement value.
