CORRECTION METHOD OF TOUCH POINT AND ELECTROMAGNETIC-TYPE TOUCH PANEL USING THE SAME

摘要

A touch point correction method is provided. Firstly, a first longitudinal base line of several longitudinal electrodes having a maximal energy is detected. Then, a right-side number of the longitudinal electrodes located in right side of the first longitudinal base line and sensing energy is detected. Then, a left-side number of the longitudinal electrodes located in left side of the longitudinal base line and sensing energy is detected. Then, a side corresponding to the largest of the right-side and left-side numbers is used as an inclined side, and a direction from the first longitudinal base line towards the inclined side is defined as an inclined direction. Then, a second longitudinal base line of the longitudinal electrodes having a sub-maximal energy is detected. Then, the sensing point is corrected by correction toward a reverse direction of the inclined direction according to ratio of the sub-maximal energy to the maximal energy.
