Classification: CPC G | IPC G

Claim 8:
9. A display device, comprising:
a display panel including a pixel, wherein the pixel includes a light-emitting element and a driving transistor configured to provide a driving current to the light-emitting element in response to a voltage between a gate electrode and a source electrode of the driving transistor, the gate electrode of the driving transistor is electrically coupled to a data line, and the source electrode of the driving transistor is electrically coupled to a readout line; and
a data driver configured to provide a data signal to the data line and to provide a reference voltage to the readout line,
wherein one frame period includes a first sub-frame period and a second sub-frame period,
wherein the data driver is configured to provide a first reference voltage to the readout line during the first sub-frame period, and to provide a second reference voltage to the readout line during the second sub-frame period,
wherein the second reference voltage is different from the first reference voltage and varies dependent on the data signal,
wherein the data driver is configured to provide an identical data signal to the pixel during each of the first sub-frame period and the second sub-frame period,
wherein the second reference voltage varies by stages at least twice during the second sub-frame period.
