Abstract

A display device may include display pixels configured to emit light at a luminance corresponding to a data signal, at least one auxiliary pixel configured to store an auxiliary voltage, a gate driver configured to supply a gate signal to the display pixels and the auxiliary pixel, a data driver configured to convert image data into the data signal, and supply an auxiliary voltage having a preset level to the auxiliary pixel. A sensing circuit is configured to sense a change in the auxiliary pixel for each frame, and generate compensation voltage information. A timing controller is configured to convert an image signal into the image data, and generate a driving voltage control signal. A voltage generation unit is configured to generate a driving voltage corresponding to the driving voltage control signal, and generate the reference gamma voltage based on the driving voltage.
