Abstract
A display device including: a display panel; a current compensation circuit executing a current compensation operation in which a load is calculated based on input image data, and output compensation image data is generated by compensating for the input image data based on the load; a data driver converting the compensation image data into a data voltage based on a gamma reference voltage and a data driving voltage, and outputting the data voltage; a current sensing circuit sensing a driving current of the display panel and comparing the driving current with a preset reference current to output a protection signal; a voltage generator generating a driving voltage, the gamma reference voltage, and the data driving voltage; and a voltage control circuit generating a first voltage control signal to control a first target compensation value of the gamma reference voltage or the data driving voltage in response to the protection signal.
