  • Optical touch panel and coordinate information correction method and detecting device therefor
    Patent number: 8373680
    Abstract: A coordinate information correction method for an optical touch panel includes: a) determining a set of to-be-corrected included angle values according to output signals received from light detectors, each of the to-be-corrected included angle values representing an included angle between a base line and a connecting line that extends from a respective one of the light detectors to a location of an object in a light curtain region; b) calculating a set of correction values, each of which is a finite order function of a respective one of the to-be-corrected included angle values; c) calculating a set of corrected included angle values from the set of to-be-corrected included angle values and the set of correction values; and d) generating corrected coordinate information associated with the location of the object in the light curtain region from the corrected included angle values.
