Abstract
Description
図1~3に示すように、本開示の第一実施形態による車両用表示装置1は、車両内の座席に着座した乗員に対して表示を行うコンビネーションメータであり、当該車室内のインストルメントパネルに設置される。尚、装置1における「左右方向」及び「上下方向」は、車両における図1の左右方向及び上下方向と、それぞれ実質一致している。装置1における「前方」とは、車両内の乗員に表示を行う図2の左方向且つ図3の下方向、即ち当該乗員による視認側を示す。装置1における「後方」とは、車両内の乗員に対する表示方向とは反対となる図2の右方向且つ図3の上方向を示す。
図9,10に示すように本開示の第二実施形態は、第一実施形態の変形例である。第二実施形態では、第一実施形態の図2の指針光源70を図9の如く廃止し、回転指針2050に紫外光にて発光する蛍光層を形成したものである。具体的には、図10の如く回転指針2050の前面2050c及び両側面2050dに、蛍光層2051を設けたものである。蛍光層2051は、例えば蛍石粉末を溶かしたアクリル樹脂等の無色透明な透光層を、回転指針2050の母材となる透光性基材2052に、印刷等によって積層してなる。かかる蛍光層2051には、指標光源30を構成する各発光素子31からの紫外光が照射され、その結果として、回転指針2050の全体が照明される。このとき蛍光層2051は、指標表示部17の指標列18と同様に紫外光、特に近紫外光を受けて励起することで、発光表示される。尚、こうして発光表示される蛍光層2051は、例えば450~660nmに広がる波長にて白色可視光を発するように、形成されている。
図11,12に示すように本開示の第三実施形態は、第一実施形態の変形例である。第三実施形態の初期表示状態において、制御回路80からの通電制御により指標光源30の各発光素子31(図11,12では図示なし)はそれぞれ、第一実施形態と同様に設定された照射対象領域3032を回転指針50が指示するのに伴い、点灯する。換言すれば、指標光源30の各発光素子31は、それぞれの照射対象領域3032から回転指針50の指示先がずれるのに伴って、消灯する。
図13,14に示すように本開示の第四実施形態は、第一実施形態の変形例である。第四実施形態の装置1は、第一実施形態の表示板10に代えて、第一表示板4010及び第二表示板4012を備えている。第一表示板4010は、指標列18を形成する蛍光層16を有していない点を除いて、第一実施形態の表示板10と実質同一構成である。故に、第四実施形態における各モニタ20はそれぞれ、個別に対応する透過表示部14の後方において、湾曲する第一表示板4010に沿った姿勢に配置されている。
図18に示すように本開示の第五実施形態は、第四実施形態の変形例である。第五実施形態の指標光源5030において各発光素子4031の左右方向の配置範囲(即ち、最左端の発光素子4031と最右端の発光素子4031との間の範囲)は、指標表示部17の形成範囲(即ち、指標列18の延伸する範囲)に応じて設定されている。かかる設定により指標列18では、各発光素子4031が点灯により可視光を照射する照射対象領域5032は、指標列18の円弧方向に互いにずらされている。但し、指標列18の円弧方向に隣り合う照射対象領域5032は、双方の端部同士を重ねるように、互いにずれている。
以上、本開示の複数の実施形態について説明したが、本開示は、それらの実施形態に限定して解釈されるものではなく、本開示の要旨を逸脱しない範囲内において種々の実施形態及び組み合わせに適用することができる。
