Abstract
A 3D (Three-Dimensional) infrared touch system includes an infrared module for establishing two layers of infrared nets over a display device for sensing a user touch operation; and an infrared recognition module for recognizing the user touch operation sensed by the two layers of infrared nets. 3D touch is carried out by virtue of the infrared and as such, it is easy to be compatible with large-sized and oversized terminals. 3D touch for large-sized terminals is realized and great convenience is brought to the users.
