Abstract
Description
本実施の形態では、本発明の一態様のタッチパネルの構成例について説明する。以下ではタッチパネルが備えるタッチセンサとして静電容量方式のタッチセンサを適用した場合について説明する。
図1(A)は、本発明の一態様のタッチパネルモジュール10の斜視概略図である。また、図1(B)は、タッチパネルモジュール10を展開した時の斜視概略図である。タッチパネルモジュールは、タッチセンサモジュール20と、表示パネル30とが重ねて配置された構成を有する。
図2(A)は、タッチセンサ22の一部を示す上面概略図(平面概略図)である。また図2(B)は、図2(A)中の一点鎖線で囲った領域を拡大した上面概略図である。
図7乃至図9は、表示面側から見たときの画素及び画素に含まれる副画素と、導電層23の位置関係を示す概略図である。なお、ここでは導電層23を例に挙げて説明するが、導電層24及び導電層25についても、同様の構成とすることができる。
図10(A)に、タッチパネルの一部を表示面側から見たときの上面概略図を示す。図10(A)では導電層23、導電層24、導電層25、遮光層53、着色層52R、52G、52B等を示している。
以下では、タッチパネルモジュール10の断面構成例について説明する。
図12(A)に、本発明の一態様のタッチパネルモジュールの断面概略図を示す。図12(A)に示すタッチパネルモジュールは、一対の基板間にタッチセンサを構成する容量素子と、表示素子とを有するため、薄型化を図ることができる。
以下では、上記に示す各構成要素について説明する。
ここで、可撓性を有するタッチパネルを作製する方法について説明する。
図15に、図12(A)とは構成の一部の異なる断面構成例を示す。なお、以下では上記と重複する部分については説明を省略し、相違点について説明する。
本実施の形態では、本発明の一態様のタッチパネルの駆動方法の例について、図面を参照して説明する。
図16(A)は、相互容量方式のタッチセンサの構成を示すブロック図である。図16(A)では、パルス電圧出力回路601、電流検出回路602を示している。なお図16(A)では、パルス電圧が与えられる電極621、電流の変化を検知する電極622をそれぞれ、X1−X6、Y1−Y6のそれぞれ6本の配線として示している。また図16(A)は、電極621および電極622が重畳することで形成される容量603を図示している。なお、電極621と電極622とはその機能を互いに置き換えてもよい。
本実施の形態では、本発明の一態様を適用して作製できる電子機器及び照明装置について、図18及び図19を用いて説明する。
本実施例では、可撓性を有する表示パネルの対向基板(表示面側の基板)にタッチセンサを作りこむ、インセル型のタッチパネルを作製した。さらに、タッチセンサの電極をメタルメッシュ形状にすることで、タッチセンサと表示パネルとの負荷容量を低減する構成とした。このような構成により、使用者によって自由に折り畳みが可能な程度に、タッチパネル全体の厚さを薄くすることができる。また、負荷容量が小さいことで表示パネルからタッチセンサへのノイズの影響が抑制され、誤検出や検出不可といった不具合が生じることを抑制することができる。
図21(A)乃至(C)に作製したタッチパネルの写真を示す。図21(A)は表示パネルを広げた状態、図21(B)は3つに折り畳んだ状態、図21(C)は、途中の状態でタッチ操作を行っている様子をそれぞれ示している。タッチパネルの表面が平面である部分、凸状である部分、及び凹状である部分のそれぞれで、正常に検出できることを確認した。
続いて、作製したタッチパネルの受信電極と、表示パネルとの間の寄生容量と寄生抵抗を、周波数ごとに測定した。測定は、LCRメータ(アジレント・テクノロジー株式会社製、4275A)を用いて行った。
続いて、作製したタッチパネルに対し、曲げ試験を行った結果について説明する。曲げ試験は、曲率半径5mmと、3mmの2条件について、それぞれ2秒間に1回の曲げ伸ばし動作を10万回行った。また曲げ伸ばし動作は、表示面が内側となる曲げと、表示面が外側になる曲げの2通りについて行った。10万回の曲げ伸ばし動作後でも、正常な表示と、正常なタッチ検出ができることを確認した。
