Abstract
Description
本実施の形態では、本発明の一態様のタッチパネルについて説明する。
本実施の形態では、本発明の一態様のタッチセンサについて説明する。
本実施の形態では、本発明の一態様のタッチセンサについて説明する。
本実施の形態で説明するタッチセンサ100は、検知ユニット10U、走査線G1、信号線DL、及び可撓性基板16を有する(図7(A))。複数の検知ユニット10Uは、n行m列(n及びmは1以上の自然数)のマトリクス状に配置される。走査線G1は、行方向に配置される複数の検知ユニット10Uと電気的に接続される。信号線DLは、列方向に配置される複数の検知ユニット10Uと電気的に接続される。また、駆動回路GDと変換器CONVを有していてもよい。同一の工程で形成できるトランジスタを用いて、複数の検知ユニット10U、駆動回路GD、及び変換器CONVを構成することができる。
第1のステップにおいて、第3のトランジスタM3を導通状態にした後に非導通状態にするリセット信号をゲートに供給し、検知素子Cの第2の電極の電位を所定の電位にする(図7(C)期間T1参照)。
第2のステップにおいて、第2のトランジスタM2を導通状態にする選択信号をゲートに供給し、第1のトランジスタM1の第2の電極を信号線DLに電気的に接続する。
第3のステップにおいて、制御信号を検知素子Cの第1の電極に供給し、制御信号及び検知素子Cの容量に基づいて変化する電位を第1のトランジスタM1のゲートに供給する。
第4のステップにおいて、第1のトランジスタM1のゲートの電位の変化がもたらす信号を信号線DLに供給する。
第5のステップにおいて、第2のトランジスタM2を非導通状態にする選択信号をゲートに供給する。
本実施の形態で説明するタッチセンサ100Bは、検知ユニット10Uに換えて検知ユニット10UBを備える点が図7を参照しながら説明するタッチセンサ100とは異なる。
第1のステップにおいて、第3のトランジスタM3を導通状態にした後に非導通状態にするリセット信号をゲートに供給し、検知素子Cの第2の電極の電位を所定の電位にする(図8(C)期間T1参照)。
第2のステップにおいて、選択信号を検知素子Cの第1の電極に供給し、選択信号及び検知素子Cの容量に基づいて変化する電位を第1のトランジスタM1のゲートに供給する(図8(C)期間T2参照)。
第3のステップにおいて、第1のトランジスタM1のゲートの電位の変化がもたらす信号を信号線DLに供給する。
本実施の形態では、本発明の一態様の表示パネルと、該表示パネルの作製方法について説明する。
図9(A)に発光装置の平面図を示し、図9(A)における一点鎖線A1−A2間の断面図の一例を図9(C)に示す。具体例1で示す発光装置は、カラーフィルタ方式を用いたトップエミッション型の発光装置である。本実施の形態において、発光装置は、例えば、R(赤)、G(緑)、B(青)の3色の副画素で1つの色を表現する構成や、R(赤)、G(緑)、B(青)、W(白)の4色の副画素で1つの色を表現する構成、R(赤)、G(緑)、B(青)、Y(黄)の4色の副画素で1つの色を表現する構成等が適用できる。色要素としては特に限定はなく、RGBWY以外の色を用いてもよく、例えば、シアン、マゼンタなどで構成されてもよい。
図9(B)に発光装置の平面図を示し、図9(B)における一点鎖線A3−A4間の断面図の一例を図9(D)に示す。具体例2で示す発光装置は、具体例1とは異なる、カラーフィルタ方式を用いたトップエミッション型の発光装置である。ここでは、具体例1と異なる点のみ詳述し、具体例1と共通する点は説明を省略する。
図10(A)に発光装置の平面図を示し、図10(A)における一点鎖線A5−A6間の断面図の一例を図10(C)に示す。具体例3で示す発光装置は、塗り分け方式を用いたトップエミッション型の発光装置である。
図10(B)に発光装置の平面図を示し、図10(B)における一点鎖線A7−A8間の断面図の一例を図10(D)に示す。具体例4で示す発光装置は、カラーフィルタ方式を用いたボトムエミッション型の発光装置である。
図10(E)に具体例1〜4とは異なる発光装置の例を示す。
次に、発光装置に用いることができる材料等を説明する。なお、本明細書中で先に説明した構成については説明を省略する場合がある。
次に、本発明の一態様の表示パネルの作製方法を例示する。ここでは、図9(A)、図9(C)に示すカラーフィルタ方式を用いたトップエミッション構造の発光装置(上記具体例1)を作製する例を示す。
本実施の形態では、本発明の一態様のタッチパネル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14及び図15を用いて説明する。
まず、可撓性を有する表示パネルと可撓性を有するタッチセンサを作製した。いずれも作製基板であるガラス基板上に素子を形成し、作製基板から該素子を剥離して、可撓性基板上に該素子を転置した。剥離層としては、タングステン膜と、該タングステン膜上の酸化タングステン膜の積層構造を形成した。作製方法の詳細は実施の形態2〜3を参酌できる。
