Abstract
A display driving circuit for receiving image data from a host and driving a display panel, the display driving circuit including: an interface configured to receive the image data from the host; and a timing controller configured to control a first interrupt signal for waking up the host in a low-power mode and to control a second interrupt signal based on a light emission control signal, wherein the light emission control signal is for controlling a light emission time of a pixel included in the display panel, and wherein the timing controller is further configured to control a level of the second interrupt signal based on whether the image data has started to be received from the host in response to the first interrupt signal and the second interrupt signal.
