Description
この発明の前記ならびにそのほかの目的と新規な特徴は、本明細書の記述および添付図面から明らかになるであろう。
(1) クロックパルスに同期してシリアルに入力された画像データを取り込み、表示タイミング信号に従ってシリアルに取り込まれた画像データに基づいて形成された表示出力信号をパラレルに出力させる液晶駆動回路に入力端子の他に出力回路と出力端子を設けておき、複数からなる液晶駆動回路を縦列形態に接続し、液晶駆動回路における内部配線及び出力回路を遅延手段として用いて各液晶駆動回路毎の表示出力信号の出力タイミングが時間的に分散されるようにすることにより、高精細化や大画面化においても、実装基板上の電源線に流れるピーク電流値を低減されるので電源ノイズによる表示品質の低下や誤動作を防止できるという効果が得られる。
Claims (3)
- 信号線と走査線とがマトリックス配置されている表示領域を備えた液晶表示パネルを有するアクティブマトリクス型液晶表示装置において、
複数本の信号線が接続された半導体集積回路が複数個前記表示領域を備えた液晶表示パネルの周辺に配置されており、
前記半導体集積回路は、画像データに基づいて表示出力信号を形成して前記表示領域に出力させるものであり、
前記画像データ、及び前記表示領域に前記表示出力信号を出力させる表示タイミング信号は、隣接する半導体集積回路を介して順にそれぞれの半導体集積回路に供給されており、
前記半導体集積回路は、前記画素データ及び前記表示タイミング信号を出力するバッファ回路を有してテープ部材に搭載されており、
前記画像データ及び前記表示タイミング信号は、前記テープ部材を介して隣接する前記半導体集積回路に供給される液晶表示装置。 - 前記テープ部材は、前記液晶表示パネルの周辺に配置されているプリント基板上に配置されている請求項1に記載の液晶表示装置。
- 前記画像データ及び前記表示タイミング信号は、所定の数の半導体集積回路毎に、その一端の半導体集積回路に供給される請求項1又は2に記載の液晶表示装置。
