An interactive display system includes an input device and an image interaction module. The input device has a touch portion including a built-in first light-emitting module and a built-in second light-emitting module. The image interaction module includes a display module, a first image-capturing module, a second image-capturing module and a processing module. The processing module captures invisible light generated by the first light-emitting module through the first image-capturing module, for determining and obtaining the position of the touch portion. The processing module captures visible light generated by the second light-emitting module through the second image-capturing module according to the position of the touch portion, for determining and obtaining a predetermined color light source provided by the visible light generated by the second light-emitting module.
