Abstract
【解決手段】液晶表示部1と、前記液晶表示部1の周囲温度を検知する温度検知部3と、前記液晶表示部1の表示を更新させる制御部4とを備えた液晶表示装置であって、所定温度よりも低い低温領域を複数の温度範囲で区分すると共に、低温側ほど長くなるよう、区分毎に前記液晶表示部の表示の更新時間を設定し、前記制御部4は、前記温度検知部3による検知温度が属する区分に対応した更新時間に基づいて前記液晶表示部の表示を更新させる。
【選択図】図3
Description
本実施形態の液晶表示装置は、例えば車両、より具体的には、フォークリフトなどの産業用車両の運転席に取り付けられるもので、速度、走行距離、荷重重量、冷却水水温、燃料残量、エラー表示、現在時刻等の種々の情報を表示するために用いられる。この液晶表示装置は、図1(A)に示すような外観でユニット化されており、前記種々の情報を表示する部分である表示パネル11を有する液晶表示部1と、複数の選択ボタンからなる選択ボタン部2とを備えている。図1(B)(C)は表示パネル11の表示の一例を示したものであり、図1(B)では表示パネル11の中央部分である表示エリアA部11aに速度が表示された状態を示し、図1(C)では表示エリアA部11aに、持ち上げる荷重重量が表示された状態を示している。選択ボタン部2は、表示を切り替えるために操作されるものである。図1(B)(C)に示した破線部は表示エリアE部11eであり、ここにはエラーコードの表示がなされる。
次に、第2実施形態について説明する。なお、以下では前記第1実施形態との相違点についてのみ説明する(第3実施形態についても同じ)。
第3実施形態は、図8に示すように、前記の温度差ΔDを、検知温度Dが−10℃以下の場合に、検知温度Dがより低い場合をより小さくしたものである。つまり、低温領域を複数の温度範囲で区分し、その区分が、温度範囲の幅が低温側ほど狭いものとされている。
