Abstract:
1. A display device, comprising: a display unit including a plurality of pixels; and a reference voltage driver applying first reference voltage to the plurality of pixels for a data writing period when data are written in the plurality of pixels and applying second reference voltage to the plurality of pixels for a light emitting period when the plurality of pixels emit light, wherein each of the plurality of pixels includes: a reference voltage change value between the first reference voltage and the second reference voltage is determined according to a threshold voltage deviation characteristic of the display unit such that a voltage range of the data voltage of each of the plurality of pixels is included in a predetermined voltage range regardless of the threshold voltage deviation characteristic of the display unit, wherein the threshold voltage deviation characteristic of the display unit is an average value of threshold voltages of the driving transistors of the plurality of pixels of the display unit.
