OPTICAL TOUCH PANEL AND DETECTION METHOD THEREOF

摘要

An optical touch panel and a detection method thereof are provided. The detection method includes following steps. A main panel is sensed by a first optical sensor and a second optical sensor. If the first optical sensor and the second optical sensor both sense two objects approaching the main panel, and a quantity of at least one first reflection signal sensed by the first optical sensor and a quantity of at least one second reflection signal sensed by the second sensor are inconsistent, the at least one first reflection signal or the at least one second reflection signal that is not paired at a current time point is removed according to a pairing relationship between the at least one first reflection signal and the at least one second reflection signal at a previous time point.

1. A detection method of an optical touch panel, comprising:
sensing a main panel by a first optical sensor and a second optical sensor; determining whether both of the first optical sensor and the second optical sensor sense two objects approaching the main panel; when both of the first optical sensor and the second optical sensor sense the two objects approaching the main panel, determining whether a quantity of at least one first reflection signal sensed by the first optical sensor and a quantity of at least one second reflection signal sensed by the second optical sensor at a current time point are inconsistent; and when the quantity of the at least one first reflection signal sensed by the first optical sensor and the quantity of the at least one second reflection signal sensed by the second optical sensor at the current time point are inconsistent, removing the at least one first reflection signal or the at least one second reflection signal that is not paired at the current time point according to a pairing relationship between the at least one first reflection signal and the at least one second reflection signal at a previous time point.
