Abstract
A display device includes a display panel that includes a plurality of pixels, a touch panel that includes a plurality of driving lines and a plurality of sensing lines, a display driver that drives the display panel at a first display frame rate in a normal driving mode, and that drives the display panel at a second display frame rate lower than the first display frame rate in a low power driving mode, and a touch controller that drives the touch panel with a mutual capacitance sensing method in the normal driving mode, and that drive the touch panel with a self capacitance sensing method in the low power driving mode.
