Abstract: 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.

Abstract: A pixel circuit includes a driving transistor connected to a light-emitting element and capacitor connected to a gate of the driving transistor. A threshold voltage of the driving transistor is compensated during a first period based on a first voltage derived from a power supply voltage. The gate of the driving transistor is set to a second voltage during a second period, where the second voltage is derived from a data voltage stored in the capacitor. The second period includes a data program period. An operation of the pixel circuit in the first period is performed independently from an operation of the pixel circuit in the data program period. Accordingly, threshold voltage compensation and data program operations are performed in separate periods based on different voltages supplied to the driving transistor.

Abstract: A display apparatus includes a scan line driver and a data line driver. The data line driver supplies data signals to turn on or off pixel circuits connected to selected scan lines. The pixel circuits are turned on or off in sub frames. For each scan line, the sub frames are assigned in the display period based on a reference point. During a preliminary period, the scan line driver selects a scan line and the data line driving circuit supplies a data signal to the pixel circuit based on the reference point. During the display period, the scan line driver selects scan line connected to the pixel circuit in synchronization with an initiation timing of each sub frame of the display period. The data line driver supplies the data signal to the pixel circuit based on the state of the sub frame corresponding to initiation timing.

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.
