  • Publication number: 20110141051
    Abstract: The present invention relates to a touch sensing panel and a touch sensing apparatus. The touch sensing panel according to the present invention includes a substrate, and a plurality of sensing electrodes arranged on the substrate and extended in one axial direction to generate a sensed signal in accordance with a contact, wherein at least one of the plurality of sensing electrodes is arranged such that the one sensing electrode is adjacent to another sensing electrode on both sides of the one axial direction. According to the present invention, provided is a touch sensing panel in which a plurality of sensing electrodes are arranged and extend in one axial direction to minimize a bezel area, and at least one of the plurality of sensing electrodes is arranged such that the one sensing electrode is adjacent to another sensing electrode at both sides of the one axial direction to accurately determine a plurality of touch inputs.

  • Publication number: 20110025636
    Abstract: A touch sensing apparatus with improved edge touch position recognition characteristics is provided. The touch sensing apparatus includes a panel unit including a plurality of sensor electrodes arranged in a line along a first axis, a sensor unit to collect sensor data indicating a change in electrical characteristics occurring in each of the plurality of sensor electrodes, the sensor unit being connected to the plurality of sensor electrodes, and a computing unit to determine a touch position on the panel unit, to which a touch of a user is applied, based on sensor data collected from at least one sensor electrode among the plurality of sensor electrodes, wherein, among the plurality of sensor electrodes, an edge sensor electrode is located on an edge in a first axis direction, and is formed narrower in width in the first axis direction than the sensor electrodes other than the edge sensor electrode.
