Display device capable of changing frame frequency and driving method thereof
Abstract:
A display device includes a display panel including a gate driving circuit which drives gate lines, a data driving circuit which drives data lines based on an image data signal and a driving reference voltage, and a driving controller which controls the gate driving circuit in response to an image signal and a control signal and provides the image data signal and the driving reference voltage to the data driving circuit. The driving controller generates a data enable signal having a display section and a blank section in one frame based on the control signal, and when a difference between a time length of the blank section of a current frame and a time length of the blank section of a previous frame is greater than a reference value, changes the driving reference voltage to a voltage level corresponding to a current frame frequency.
