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.

The sensing driver measures a first voltage value applied to a light emitter in a pixels. The memory stores a second voltage value previously measured for the pixel. The first compensator calculates a temperature of the light emitter at a time of measuring the first voltage value, and compensates for the first voltage value based on the temperature. The second compensator compensates for input data for the pixel based on a voltage variation obtained from the temperature-compensated first voltage value and the second voltage value.
