Description

【特許請求の範囲】
【請求項１】 タッチセンサーを有し、それ自体公知のエレクトロクロミックセル又は液晶セルから成るデイスプレーデバイスに於いて、該エレクトロクロミックセル又は該液晶セルが透明なカバープレート（１）と透明な支持プレート（２）との間に配置されており、そしてその光が該カバープレート（１）に入りそれを照明する放射源（３）が該透明なカバープレート（１）の端面の少なくとも１つ上に配置されていること、かつ、その光検出立体角範囲内に該カバープレート表面の幾らか又は全部がある少なくとも１つの光検出器（４）が該支持プレート（２）上に設置されていることを特徴とするタッチセンサーを有し、それ自体公知のエレクトロクロミックセル又は液晶セルから成るデイスプレーデバイス。
【請求項２】 請求項１に記載のタッチセンサーを有するデイスプレーデバイスのタッチ認識方法に於いて、該放射源からの放射電力が周波数ｆQで時間と共に周期的に変化し、そして該光検出器からの該電気信号が、該信号の、同様に時間と共に周期的に変化しかつ該放射源からの該放射電力と同じ周波数ｆQで概略変化する様な、部分のみが顕著に評価されるように更に処理されることを特徴とするタッチセンサーを有するデイスプレーデバイスのタッチ認識方法。
