Abstract
A display device includes: a display unit including pixels, wherein each of the pixels includes stacks connected in series and each of the stacks includes a light emitting element; a storage to store pieces of stack number information, wherein each of the pieces of the stack number information indicates the number of stacks constituting an effective light source from among the stacks for each of the pixels; a compensator to generate compensated data by compensating image data based on the pieces of the stack number information; and a data driver to generate data voltages based on the compensated data and to provide the data voltages to the display unit. The pixels are to emit light with luminances corresponding to the data voltages.

A display device comprising:
- a display unit comprising pixels, wherein each of the pixels comprises stacks connected in series and each of the stacks comprises a light emitting element;
- a storage to store pieces of stack number information, wherein each of the pieces of the stack number information indicates a number of stacks constituting an effective light source from among the stacks for each of the pixels;
- a compensator to generate compensated data by compensating image data based on the pieces of the stack number information;
- and
- a data driver to generate data voltages based on the compensated data and to provide the data voltages to the display unit,
- wherein the pixels are to emit light with luminances corresponding to the data voltages.
A method of driving a display device comprising pixels, wherein each of the pixels comprises a driving transistor and stacks connected in series to a first electrode of the driving transistor and each of the stacks comprises a light emitting element, the method comprising:
- applying a first voltage to a gate electrode of the driving transistor;
- measuring a second voltage applied to the first electrode of the driving transistor in response to the first voltage;
- generating stack number information based on the second voltage, wherein the stack number information indicates a number of stacks constituting an effective light source from among the stacks for each of the pixels;
- and
- setting a data voltage applied to the gate electrode of the driving transistor based on the stack number information.
