Abstract
【解決手段】絶縁基板(201)上に形成された薄膜トランジスタ(224)を用いて構成されたアクティブマトリクス型の表示装置において、外部システム(230)から、非接触伝送路(219、220、233、234)を介して画像データを受信し増幅する回路と、画像データを処理する回(223)路と、処理された画像データを保持するメモリ回路(222)とが絶縁基板(201)上に集積されてなる表示装置。
【選択図】 図3
Description
以下、本発明の実施の形態を図面を参照しながら説明する。図3は本発明の第1の実施の形態に係るディスプレイ基板200を示し、この表示装置はいわゆるアクティブマトリクス型の表示装置である。図3のガラス基板201は図1に示す従来技術の透明基板122に対応し、これをさらに改善するものである。
図8は本発明の第2の実施の形態にかかるアクティブマトリクス型表示装置の構成図である。図8の実施例においては、外部からの圧縮された画像データを受信するための素子として、例えば金属薄膜で構成された所定の巻き回数のインダクタが使用されることに特徴を有する。
図10は本発明の第3の実施の形態にかかるディスプレイ基板200とシステム装置の作業台264を示す斜視図である。
図11は本発明の第4の実施の形態にかかる信号処理回路を示す回路図である。第1の実施の形態の絶縁基板に、非接触伝送のための送受信用のアンテナ、薄膜トランジスタを用いた送信回路及びスイッチが形成される。そして、このスイッチによりシステム装置からの受信とシステム装置への送信を切替え可能とし、受信および送信に係る双方向の信号の授受を可能とする。
図12および図13に本発明の第5の実施の形態にかかるディスプレイ基板200および光受信回路268を示す。第1の実施の形態における容量結合による信号伝送に代え、光結合により非接触の信号伝送を行うものである。
図14および図15に示す実施の形態は、図3に示すような、非接触型のシステム―ディスプレイ間インターフェイスを用いた実装の別の事例である。ディスプレイ基板200は、外部システムに形成された接続スロット274に結合して使用するため、接続スロットに挿入される結合端部278を有する。図14の事例における信号伝送の原理は2つの容量素子を用いた静電結合型の差動伝送である。但し本発明は静電結合型に限定されるわけではない。例えば誘導結合や光結合を用いることもできる。
本発明に係る非接触伝送路による画像表示は、通常の薄膜トランジスタの製造に使用されているような、例えばガラス基板上に形成されたアモルファスシリコン薄膜を用いて行うことが可能である。一般にアモルファスシリコン薄膜はアニールして使用される。
図3または図8に示すような受信回路221、メモリ222、画像展開回路223、およびコントロール回路218等に含まれる種々の論理セルは、予めセルライブラリに記憶された各論理部分に関する所定の基本構造を複数用いて形成することができる。これらの論理セルのうちCMOSによるインバータ回路セル、AND回路セル、XOR回路セル、および半加算器回路の構成について以下説明する。
