Abstract: A display system includes: a host processor which outputs first image data and outputs scan frequency information and a partial scan enable signal, based on an image driving frequency; a display module controlled by the host processor; and an interface. The display module includes: a display driving circuit which controls a selection of pixel rows to which the data signals are supplied based on the scan frequency information and the partial scan enable signal; and a display panel which displays an image on selected pixel rows based on the data signals. In a video mode of the interface, the host processor divides and outputs the first image data through the interface during transmission periods, based on the image driving frequency, and suspends an output of the first image data through the interface during suspend periods.
