Abstract
An exemplary method of identifying a touch event on a touch panel is provided. The touch panel includes a plurality of sensing blocks. The sensing blocks have a plurality of corresponding sensing values generated in response to the touch event. The exemplary method includes the following steps: selecting a processing region on the touch panel, wherein the processing region comprises at least a portion of sensing blocks each having a sensing value greater than a threshold; deriving a first value and a second value from sensing values of sensing blocks included in the processing region; calculating a ratio of the first value to the second value; and identifying the touch event according to at least the ratio.
