Abstract:
A method of detecting a touch position and a touch panel for performing the method are disclosed. In the above-mentioned method, a plurality of scan signals is sequentially supplied to a plurality of first sensor lines arranged in a first direction. Then, at least one of the scan signals is analyzed based on touch events, which is transferred from the first sensor lines to a plurality of second sensor lines arranged in a second direction substantially across to the first direction, and then at least one of touch positions is detected. Therefore, a plurality of scan signals is sequentially applied to the first sensor lines in the first direction, so that a plurality of touch events is simultaneously detected so that a plurality of touch positions may be detected.
