Summary: | PROBLEM TO BE SOLVED: To provide a capacitance type touch input device that achieves minimization of effects of noise and reduction of detection errors of touch positions and touch pressures.SOLUTION: A touch input device 1000 includes a touch sensor 100 that includes a plurality of touch electrodes, a display panel, and a reference potential layer. The touch sensor is completely laminated with the display panel, and the touch sensor and the display panel warp upon being applied with the touch pressure. The reference potential layer is disposed separate from the touch sensor. The reference potential layer is capable of detecting the touch position on the basis of a first capacitance that is detected from the touch electrodes and varies according to approach of a customer to the touch sensor, and detecting magnitude of the touch pressure on the basis of a second capacitance that is detected from the touch electrodes and varies according to a distance between the touch sensor and the reference potential layer.SELECTED DRAWING: Figure 1
【課題】ノイズの影響を最小化し、タッチ位置やタッチ圧力の検出誤差を減らした静電容量型タッチ入力装置を提供する。【解決手段】タッチ入力装置1000は、複数のタッチ電極を含むタッチセンサ100と、ディスプレイパネルと、基準電位層とを含む。タッチセンサはディスプレイパネルと完全ラミネーションされ、タッチ圧力が印加されれば、タッチセンサ及びディスプレイパネルが撓む。基準電位層は、タッチセンサと離隔されて配置され、タッチ電極から検出され、客体がタッチセンサに近接することによって変わる第1静電容量に基づいてタッチ位置を検出し、さらに、タッチ電極から検出され、タッチセンサと基準電位層との間の距離によって変わる第2静電容量に基づいてタッチ圧力の大きさを検出することができる。【選択図】図1 |
