Abstract:
1. A diagnostic system for an optical touch module, used for testing an optical touch control module comprising a touch surface and an optical capturing module, the optical capturing module is disposed on the touch surface to capture a image signal from the touch surface, the diagnostic system comprising: a controlling module, electrically connected to the optical capturing module; a first test element, disposed on the touch surface for allowing the optical capturing module to capture a first test signal; a second test element, disposed on the touch surface for allowing the optical capturing module to capture a second test signal; wherein the first test element and the second test element are used for simulating a stylus or a finger; wherein a position of the first test element and second test element forms a maximum touch range of the touch surface for providing to a user; and a rotary fixture, electrically connected to the controlling module and used for contacting to the optical capturing module, wherein the controlling module determines whether the image signal has the first test signal and the second test signal, if not, the controlling module controls the rotary fixture to rotate the optical capturing module to adjust a capturing direction.
