Description
図1は、この発明に係るタッチパネル装置の基本構成を示した図である。図1に示したように、タッチパネル装置は、画素マトリックスを有する液晶パネル1と、液晶パネル1のゲートラインGLを駆動するための駆動回路であるゲートドライバ2と、液晶パネル1のデータラインDLを駆動するための駆動回路であるデータドライバ3と、ゲートドライバ2とデータドライバ3とを制御するためのタイミングコントローラ4とを備える。また、液晶パネル1のタッチ面上(表示エリア)に指やタッチペン等の接触物が接触したときに、それによって、静電容量型タッチパネル装置であれば静電容量が変化し、抵抗型タッチパネル装置であれば抵抗値が変化するので、それに基づく電流値の変化に基づいて、当該接触物のタッチ位置の位置座標を計算する信号処理回路5と、当該位置座標に対応する内容を内部メモリ等の記憶装置7から抽出し、それに基づいて、文字や画像を液晶パネル1に表示したり、あるいは、必要な処理を行って他の装置に信号を出力したりする制御回路6とを備える。
