A display apparatus comprising: a display panel configured to display an image based on input image data including input frame images; a gate driver configured to output a gate signal to the display panel; a data driver configured to output a data voltage to the display panel; a driving controller; a host configured to output the input image data to the driving controller; the driving controller further configured to determine a normal driving mode having a driving frequency which is a normal driving frequency when the input image data received from the host represents a video image and a low frequency driving mode having a driving frequency of less than the normal driving mode when the input image data received from the host represents a still image, and to control an operation of the gate driver and an operation of the data driver in accordance with the determined normal driving mode or the determined low frequency driving mode; a touch driver configured to detect a touch event occurring on the display panel during a frame, and to output a touch interrupt signal directly to the driving controller, wherein the touch interrupt signal represents the touch event, wherein the touch driver is configured to generate a touch coordinate signal representing a touch position, and to output the touch interrupt signal and the touch coordinate signal to the host, wherein the driving controller is configured to perceive the touch event immediately on receipt of the touch interrupt signal, and wherein, when the display panel is driven in the low frequency driving mode, the driving controller is further configured in response to the touch event to drive the display panel in the normal driving mode in a right next frame of the frame. a display panel configured to display an image based on input image data including input frame images; a gate driver configured to output a gate signal to the display panel; a data driver configured to output a data voltage to the display panel; a driving controller; a host configured to output the input image data to the driving controller; the driving controller further configured to determine a normal driving mode having a driving frequency which is a normal driving frequency when the input image data received from the host represents a video image and a low frequency driving mode having a driving frequency of less than the normal driving mode when the input image data received from the host represents a still image, and to control an operation of the gate driver and an operation of the data driver in accordance with the determined normal driving mode or the determined low frequency driving mode; a touch driver configured to detect a touch event occurring on the display panel during a frame, and to output a touch interrupt signal directly to the driving controller, wherein the touch interrupt signal represents the touch event, wherein the touch driver is configured to generate a touch coordinate signal representing a touch position, and to output the touch interrupt signal and the touch coordinate signal to the host, wherein the driving controller is configured to perceive the touch event immediately on receipt of the touch interrupt signal, and wherein, when the display panel is driven in the low frequency driving mode, the driving controller is further configured in response to the touch event to drive the display panel in the normal driving mode in a right next frame of the frame. <EOS>
