Abstract
【解決手段】表示制御部60は、液晶パネル10の第一画素領域14において通常時及び特定時にメータ画像を表示する画素の階調比率をメータ表示階調比率として制御し、液晶パネル10の第二画素領域18において特定時に外界画像を表示する画素の階調比率を外界表示階調比率として制御する。そして、表示制御部60は、メータ及び外界表示階調比率を最大比率R1max,R2maxに保持した状態で、基準値Cbよりも明るい側の調整値に従って光源20の発光輝度を可変にする第一制御モードと、光源20の発光輝度を最小輝度Lminに保持した状態で、基準値Cbよりも暗い側の調整値に従ってメータ表示階調比率を可変にする一方、外界表示階調比率を最大比率R2maxに保持する第二制御モードとを切換え実行する。
【選択図】図1
Description
図2,3は、本発明の第一実施形態による車両用表示装置1の概略構成を示し、図4は、装置1の電気回路構成を示している。
制御回路62は、入力調整値が基準値Cbよりも明るい側となる場合に第一制御モードを実行する。
制御回路62は、入力調整値が基準値Cbよりも暗い側となる場合に第二制御モードを実行する。
本発明の第二実施形態は、第一実施形態の変形例である。尚、以下では、第一実施形態と異なる点を中心に説明する。
入力調整値が基準値Cbよりも明るい側となる場合に実行される第一制御モードにおいて、制御回路262は、光源20の発光輝度並びに液晶パネル210における第一画素領域14のメータ表示階調比率を、第一実施形態の第一制御モードと同様(図14)に制御する。これにより第一画素領域14においては、最大明るさB1max及び中間明るさB1mid間の範囲ΔB1b(図15)のうち入力調整値に従う明るさにて、メータ画像12が表示されることとなる。
入力調整値が基準値Cbよりも暗い側となる場合に実行される第二制御モードにおいて制御回路262は、光源20の発光輝度並びに液晶パネル210における第一画素領域14のメータ表示階調比率を、第一実施形態の第二制御モードと同様(図14)に制御する。これにより第一画素領域14においては、中間明るさB1mid及び最小明るさB1min間の範囲ΔB1d(図15)のうち入力調整値に従う明るさにて、メータ画像12が表示されることとなる。
以上、本発明の複数の実施形態について説明してきたが、本発明はそれらの実施形態に限定して解釈されるものではなく、その要旨を逸脱しない範囲内において種々の実施形態に適用することができる。
