Abstract
A display device and a display driving method are disclosed. The display device includes a display panel including gate lines, data lines, and a plurality of subpixels including a plurality of driving transistors, a gate driving circuit configured to apply scan signals to the gate lines, a data driving circuit configured to convert image data into data voltages and apply the data voltages to the data lines, and a timing controller configured to compensate the data voltages applied to the plurality of driving transistors based on a real-time sensing process of characteristic values of the plurality of driving transistors, and control an application of a recovery voltage to at least one driving transistor of the plurality of driving transistors a plurality of times within a blank period of a frame period based on a reference period to reset the at least one driving transistor during the blank period.
