An interactive display system includes a display device and a user device. The display device includes a controlling unit and lighting units, and the controlling unit transmits a color signal to the lighting units. When the user device emits an active light signal to the lighting units, the lighting unit that receives the active light signal lights up according to the color signal. Namely, when the user uses the user device to emit the active light signal to the lighting units of the display device, the lighting units illuminated by the active light signal can light up. Therefore, the user can use the display device as a canvas, and the user can draw a picture or write a memo on the display device for interacting with the display device of the interactive display system.
