Description
<実施例1>
[構成]
図1は、本発明の第1実施例による全面発光アクティブマトリクス型有機電界発光表示装置の平面図であり、図2は、図1のA部分、即ち、光感知部を拡大図示した回路図である。図3及び図4は、図1に図示しているアレー基板100中の画素部及び光感知部の断面図である。
[作用]
図5は前記光感知部Aの動作を説明するための回路図である。図6は前記光感知部Aの動作を説明するためのV−I特性グラフである。図6において■は、外部光がないときの光電流を示し、●は、外部光が入射したときの光電流を示す。
以下、図3乃至図4を参照して図1に図示されたアレー基板100の製造工程を説明する。
<実施例2>
[構成]
次に、本発明の第2実施例における背面発光アクティブマトリクス型有機電界発光表示装置について、図を用いて詳細に説明する。図7及び図8は、本発明の第2実施例による背面発光アクティブマトリクス型有機電界発光表示装置において、画素部及び光感知部をそれぞれ図示した断面図である。本発明の第2実施例による背面発光アクティブマトリクス型有機電界発光表示装置は、第1実施例による全面発光アクティブマトリクス型有機電界発光表示装置とは第1及び第2電極を除いては同じである。従って、実施例1と同じ構成要素は同じ参照符号を使用し、それに関する説明は省略する。
[作用]
図7及び図8を参照すると、背面発光アクティブマトリクス型有機電界発光表示装置は、有機電界発光素子ELで発生した光がその下部の薄膜トランジスタが形成された基板100を通じて外部に放出される。このため、前記基板100は表示画面の方に配置される。
<実施例3>
[構成]
次に、本発明の第3実施例について、図を用いて詳細に説明する。図9は、本発明の第3実施例による半透過型液晶表示装置の平面図である。図10は、図9に図示した半透過型液晶表示装置の光感知部の回路図であり、図11は、前記光感知部の断面図である。
[作用]
前記光感知部260の動作を見ると次のようである。まず、光感知用第1薄膜トランジスタTs1に外部光が入射されると、前記第1薄膜トランジスタTs1のゲート電極202aに連結されたVgoff信号ラインにはマイナスの電圧を印加し、また、第1薄膜トランジスタTs1のドレーン電極208aに連結されたデータラインVdataにはプラスの電圧を印加して、前記第1薄膜トランジスタTs1をオフ状態にする。そうすると、外部光が入射された第1薄膜トランジスタTs1では、外部光が入射されない第2薄膜トランジスタTs2に比べて相当な大きさのリーク電流が発生する。
<第3実施例:製造工程>
以下、図11を参照して図9に図示されたアレー基板200の製造工程を説明する。
<実施例4>
[構成と作用]
次に、本発明の第4実施例について図を用いて説明する。図12は、本発明の第4実施例による半透過型液晶表示装置の光感知部の回路図である。
<実施例5>
[構成と作用]
次に、本発明の第5実施例について図を用いて説明する。図13は、本発明の第5実施例による半透過型液晶表示装置の光感知部の回路図である。図13を参照すると、本発明の第5実施例による半透過型液晶表示装置の光感知部は、一つの非晶質シリコン薄膜トランジスタTsのみを用いて外部光の強さを検出する。前記薄膜トランジスタTsのゲート電極はVoff信号ラインに連結され、ドレーン電極はデータラインVdataに接続され、ソース電極は読み出しラインROLに連結される。
<実施例6>
[構成と作用]
次に、本発明の第6実施例について図を用いて説明する。図14は、本発明の第6実施例による半透過型液晶表示装置の光感知部の回路図であり、図15は、前記光感知部のリーク電流を測定したグラフである。図15で、“OFF”は、外部光がないときのリーク電流を示し、“ON”は、外部光が光感知用薄膜トランジスタTsに入射したときのリーク電流を示す。
