Abstract
A display device includes a display panel comprising subpixels, data lines, and driving transistors, a data driving circuit configured to convert image data into data voltages and apply the data voltages to the data lines, and a timing the controller configured to control the data driving circuit and switch between a first compensation mode and a second compensation mode responsive to a driving frequency variation of the display device during exceeding a reference value, wherein, in the first compensation mode, the data voltages of the driving transistors in an entire area of the display panel are compensated through a real-time sensing process of characteristic values of the driving transistors during a blank period, and in the second compensation mode, the data voltages of the driving transistors in at least a partial area of the display panel are compensated according to a temperature value of the display panel.
