A display device and a method of driving the display device are provided. The display device includes a display panel including a plurality of pixels, a timing controller, a data driver, and a scale factor generation circuit. The timing controller calculates a frame load value corresponding to an image frame of input image data and generates image data by scaling a gradation value of the input image data using a scaling factor. The data driver generates a data signal corresponding to the image data and supplies the data signal to the plurality of pixels. The scaling factor generation circuit sets a reference range based on a temperature of the display panel and a global current value flowing through the plurality of pixels, and generates a scaling factor included in the reference range based on the frame load value and the global current value. 提供了显示装置和驱动显示装置的方法。显示装置包括包含多个像素的显示面板、时序控制器、数据驱动器和比例因子生成电路。时序控制器计算与输入图像数据的图像帧对应的帧负载值并且通过使用比例因子将输入图像数据的灰度值进行缩放来生成图像数据。数据驱动器生成与图像数据对应的数据信号并且将数据信号供给到多个像素。比例因子生成电路基于显示面板的温度和
