OPTICAL TOUCH DEVICE
First Claim
1. An optical touch device comprising:
- a display panel whereon a coordinate detecting area is formed;
at least one optical transceiver disposed on a corner of the display panel for transceiving a plurality of beams travelling along an edge of the coordinate detecting area so as to form an optical virtual frame;
at least one image capturing module disposed on a corner of the display panel for capturing surroundings of an object; and
a control module coupled to the at least one image capturing module for determining whether to calculate a coordinate value of the object according to whether the object blocks the optical virtual frame by the captured surroundings of the object.
