Summary: | To provide a touch panel system capable of simultaneously detecting a position of an indicator and a magnitude of pressing, and a display device provided with the touch panel system.SOLUTION: A touch panel system S includes: a touch panel 1 that is provided with a drive electrode, a position detection electrode and a press detection electrode; and a controller 2 that gives a drive signal to the drive electrode and acquires a signal value from each of the position detection electrode and the press detection electrode. The controller 2 detects a position of an indicator based on the signal value obtained from the position detection electrode, and calculates a magnitude of pressing by the indicator based on the signal value within a press detection range corresponding to the position of the detected indicator among the signal values obtained from the press detection electrode.SELECTED DRAWING: Figure 6
【課題】指示体の位置及び押圧の大きさを同時に検出することが可能なタッチパネルシステムと、当該タッチパネルシステムを備えた表示装置を提供する。【解決手段】タッチパネルシステムSは、ドライブ電極、位置検出電極及び押圧検出電極を備えたタッチパネル1と、ドライブ電極に駆動信号を与え位置検出電極及び押圧検出電極のそれぞれから信号値を取得するコントローラ2と、を備える。コントローラ2は、位置検出電極から得られた信号値に基づいて指示体の位置を検出し、押圧検出電極から得られた信号値のうち、検出した指示体の位置に応じた押圧検出範囲内の信号値に基づいて、指示体による押圧の大きさを算出する。【選択図】図6 |
