Abstract
本発明は、例えば、新規な誤書換防止回路を備えたディスプレイ装置を提供することを目的とするものである。
【解決手段】
本発明は、上記目的を達成するために、例えば、外部装置からのビデオ信号を用いて所望の映像を表示するディスプレイ装置において、該ディスプレイ装置に関する情報を記憶するメモリ回路と、該外部装置に対して該メモリ回路からの情報の読出を許可する読出許可手段と、該ディスプレイ装置もしくは該外部装置の少なくともいずれか一方の電源がONした場合に該メモリ回路への書込みを禁止する書込禁止手段と、該読出許可手段で用いられる外部端子からの信号により該メモリ回路への書込みを許可する書込許可手段とを備えたものである。
【選択図】 図2
Description
なお、数1の右辺はVHPDを基準とした場合のメモリ13の制御端子WPの電圧である。
このように、数2を満足するように設定すれば、映像信号源機器1から+5V電源が供給されなくとも、電源11から+5Vが供給されれば、図2から明らかなように、メモリ13の制御端子WPの電圧は、メモリ書込みが禁止されるVIH以上の“H”レベルとなるため、書込可能状態になることはない。
但し、VHPD<0V
このようにすれば、図2から明らかなように、メモリ13の制御端子WPは、書込可能状態となるVIL以下の“L”レベルとなり、書込可能状態とすることができる。
