  • Publication number: 20140347314
    Abstract: A method of detecting a touch force capable of detecting a touch force applied to a touch panel by an object is provided. The method of detecting a touch force comprises following steps. The touch panel is provided. A relation between a sensing capacitance of the touch panel and the touch force is built. The object touches the touch panel, and a detecting sensing capacitance of the touch panel is obtained. A detecting result is obtained according the relation and the detecting sensing capacitance. Moreover, a detector is also provided.

  • Publication number: 20140232660
    Abstract: An exemplary method for determining a position of a touch event on a touch panel includes at least the following steps: scanning the touch panel by utilizing a first touch event detection threshold, and accordingly obtaining touch signal information corresponding to the touch event on the touch panel; determining if the touch panel is in a specific touch mode according to the touch signal information; and when it is determined that the touch panel is in the specific touch mode, setting a second touch event detection threshold that is different from the first touch event detection threshold, and scanning the touch panel by utilizing the second touch event detection threshold to obtain the position of the touch event.

  • Publication number: 20140232661
    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.
