Abstract
【解決手段】本発明によるタッチ感知装置は、多数のタッチセンサーを含むタッチセンサーアレイと、このタッチセンサーアレイからのタッチデータそれぞれを、隣り合う他のタッチデータとの差の値に補正して補正値を発生させ、その補正値にオフセット値を加算してタッチデータのスイングレベルを補正するスイングレベル補正部とを備えていることを特徴とする。また、その出力補正方法は主に上記スイングレベル補正部において行われる。
【選択図】図19
Description
また、タッチセンサーアレイ14は図3のように、タッチセンサーTSを表示パネル10内に内蔵することができる。例えば、タッチセンサーアレイ14は上部偏光板POL1と上部ガラス基板GLS1の間に狭持されるタッチセンサーTSを含むことができる。図2及び図3のようなタッチセンサーアレイ14は抵抗膜方式のタッチセンサー、静電容量方式のタッチセンサー、表面弾性波方式のタッチセンサー、赤外線方式のタッチセンサーの内の何れか一つに具現することができる。
