In a display device according to the present invention, a current compensation block calculates a load on the basis of input image data, compensates the input image data on the basis of the load, and outputs compensated image data. The data driver converts the compensated image data into a data voltage based on a gamma reference voltage and a data driving voltage, and outputs the data voltage. The current sensing block senses a driving current of the display panel and compares the driving current with a reference current to output a protection signal. The voltage generator generates a gamma reference voltage and a data driving voltage. A voltage control block generates a voltage control signal for controlling at least one of the gamma reference voltage and the data driving voltage in response to the protection signal, and supplies the voltage control signal to the voltage generator. 在根据本发明的显示装置中，电流补偿块基于输入图像数据算出负载，并基于所述负载补偿输入图像数据来输出补偿图像数据。数据驱动器基于伽马基准电压以及数据驱动电压将所述补偿图像数据转换为数据电压，并输出数据电压。电流感测块感测所述显示面板的驱动电流，并比较所述驱动
