摘要： An embodiment of the present invention provides a display system, and the display system comprises a light beam emitting device, emitting a first light beam for marking an input position and a second light beam for confirming the input position, the first light beam being visible light, and the second light beam differing from the first light beam; and a display device, comprising a displaying area, photo-sensitive devices distributed within the displaying area, processing devices coupled with the photo-sensitive devices. The photo-sensitive devices are used for sensing the second light beam projected upon the displaying area and achieving a sensing result; the processing devices are used for determining the projecting position of the second light beam upon the displaying area according to the sensing result, and performing a corresponding operation based on the sensing result. The present invention is capable of performing remote touch operation on the display device.
