Instead of eroding the original display, the display surface may be divided into a plurality of areas, and the original display or the new display may be allocated to each divided area. However, in such a case, the original display is reduced by the division. It is also conceivable to take a large area allocated to the original display and to make the area allocated to the new display very small.

[構成]
図1は、本技術の第1の実施の形態に係る電子機器1の斜視構成の一例を表す。図2は、図1の電子機器1のA-A'線での断面構成の一例を表す。電子機器1は、2画面表示を行うことが可能である。2画面表示とは、2つの領域に映像を表示することを指している。電子機器1は、映像表示を行うことの可能な2つの領域のうち、少なくとも一方の領域に映像を表示する。電子機器1は、2画面表示を行うことが可能であるにもかかわらず、物理的な映像表示面を1つしか備えていない。つまり、電子機器1は、2画面表示を行うにあたって物理的な2つの映像表示面を必要としていない。このことは、上述の2画面表示以外の表示を行うために別途、1または複数の映像表示面を設けることを排除するものではない。
表示部10は、表示部20と比べて、主面50Aの下端寄り(すなわち電子機器1の観察者1000に近い場所)に配置されている。本実施の形態では、表示部10が表示部20との関係で主たる表示を担っており、表示部20の映像表示領域の面積よりも広い面積で映像表示を行う。表示部10は、主面50Aの裏面と平行に表示パネルを有している。この表示パネルは、概ねランバートな映像光L1を出射し、物理的な映像表示面50Sに実像としての映像100を生成する(後述の図6参照)。映像100が、本技術の「第1映像」の一具体例に相当する。
表示部20は、表示部10と比べて、主面50Aの上端寄り(すなわち電子機器1の観察者1000から離れた場所)に配置されている。本実施の形態では、表示部20が表示部10との関係で従たる表示を担っており、表示部10の映像表示領域の面積よりも狭い面積で映像表示を行う。表示部20は、空間中に映像を表示する。具体的には、表示部20は、空中結像させた像を映像として生成する。表示部20は、例えば、表示部10の視野角よりも狭い発散角の光線で空中結像させた像を映像として生成する。表示部20は、例えば、指向性の高い映像光L2を出射し、空中に結像した像を映像200として生成する(後述の図6参照)。映像光L2の発散角は、例えば、表示部10の視野角よりも狭くなっている。映像200が、本技術の「第2映像」の一具体例に相当する。
表示パネル21は、例えば、外部から入力される映像信号に基づいて映像を表示する平板状のパネルであり、例えば、液晶パネル、または、ELパネルである。表示パネル21は、複数の画素が行列状に配置された映像表示面を有している。各画素は、概ねランバートな発散光を発する。表示パネル21は、表示パネル21の映像表示面から発散光を発する。表示パネル21から発せられた光は、光学プレート22および保護基板52を介して外部に出射される。
図3は、光学プレート22の平面構成の一例を表す。光学プレート22は、板状の基板11を有している。ここで、光学プレート22(基板11)のうち観察者1000側の面を前面22Aとし、光学プレート22(基板11)のうち前面22Aとは反対側の面を裏面22Bとする。また、光学プレート22の前面22Aと平行な面をXY平面とし、後述する反射面11Aと平行な面をXZ平面とし、後述する反射面11Bと平行な面をYZ平面とする。また、光学プレート22(基板11)の法線AX1が、Z軸と平行となっている。
非接触入力部30は、映像表示面50Sに非接触の状態で、観察者1000の指などの物体の位置を検出することにより、検出位置に応じた信号を制御部40に出力する。非接触入力部30は、映像200の表示領域を含む空間領域を検出領域とする。非接触入力部30は、例えば、上記空間領域に向かって非可視光を出力し、出力した非可視光の戻り光を検出することにより、空間領域内に存在する物体の位置を検出する。つまり、非接触入力部30は、例えば、上記空間領域に向かって非可視光を出力し、出力した非可視光の戻り光を検出することにより、非接触入力を受け付ける。非接触入力部30は、近接センサで構成されており、例えば、赤外線センサ、超音波型センサ、静電容量型センサなどで構成されている。
制御部40は、外部から入力される映像信号に基づいて、表示部10,20を制御する。制御部40は、例えば、表示部10を駆動して、映像100だけを映像表示面50Aに表示する。また、制御部40は、例えば、図6に示したように、表示部10,20を駆動して、映像100を映像表示面50Aに表示すると共に、映像200を空中に表示する。また、制御部40は、例えば、休止していた表示部20の駆動を開始して、映像100を映像表示面50Aに表示している状態から、さらに、映像200の空中への表示を開始する。また、制御部40は、例えば、外部からの何らかの信号を検知したときに、映像200として、そのとき表示していた映像に代えて、検知した内容を知らせるサムネイルを表示する。
次に、図6を参照しつつ、電子機器1の作用・効果について説明する。
[変形例A]
図7は、上記実施の形態の電子機器1の一変形例を表す。図8は、本変形例に係る電子機器1の作用の一例を表したものである。本変形例では、表示部10が、表示部20と比べて、主面50Aの上端寄り(すなわち電子機器1の観察者1000から離れた場所)に配置されている。さらに、表示部20が、表示部10と比べて、主面50Aの下端寄り(すなわち電子機器1の観察者1000に近い場所)に配置されている。本変形例では、映像200が観察者1000寄りの空中に生成される。これにより、例えば、電子機器1が、観察者が片手で持てる程度の小型の携帯端末である場合には、観察者が電子機器1を把持した状態で親指を空中にかざすだけで、非接触入力を行うことができる。
図9は、上記実施の形態の電子機器1の一変形例を表す。図10は、本変形例に係る電子機器1の作用の一例を表したものである。本変形例では、本実施の形態では、表示部20が表示部10との関係で主たる表示を担っており、表示部10の映像表示領域の面積よりも広い面積で映像表示を行う。さらに、表示部10が表示部20との関係で従たる表示を担っており、表示部20の映像表示領域の面積よりも狭い面積で映像表示を行う。表示部10,20の位置関係は、上記実施の形態と同じである。
図11は、図1の電子機器1の一変形例を表す。図12は、図7の電子機器1の一変形例を表す。図13は、図9の電子機器1の一変形例を表す。図11、図12、図13に記載の電子機器1では、表示パネル21の代わりに、表示パネル21の機能に加えて、さらに、非接触入力部30の機能も有する表示パネル23が設けられている。つまり、表示パネル23は、非接触入力部30を内蔵している。このとき、非接触入力部30は、光学プレート22に向かって非可視光を出力し、出力した非可視光が物体で反射され、光学プレート22を透過して戻ってきた光を検出することにより、非接触入力を受け付ける。つまり、非接触入力部30は、光学プレート22を透過して光の戻り光を検出することにより、非接触入力を受け付ける。これにより、非接触入力部30を別固に設けた場合よりも、非接触入力部30を省略できた分だけ筐体50を小型化することができる。また、非接触入力部30から出力される非可視光を外部に導く光路として、光学プレート22を使うことができるので、そのような光路を別途設けた場合よりも、筐体50を小型化することができる。また、表示パネル23から出射された非可視光が、映像200の生成される箇所に集まる(集光される)ので、映像200の生成される箇所での検出感度を向上させることができる。
[構成]
次に、本技術の第2の実施の形態に係る電子機器2について説明する。図14は、電子機器2の斜視構成の一例を表す。図15は、図14の電子機器2のB-B'線での断面構成の一例を表す。電子機器2は、電子機器1と同様、2画面表示を行うことが可能である。電子機器2は、2画面表示を行うことが可能であるにもかかわらず、物理的な映像表示面を1つしか備えていない。つまり、電子機器2は、2画面表示を行うにあたって物理的な2つの映像表示面を必要としていない。このことは、上述の2画面表示以外の表示を行うために別途、1または複数の映像表示面を設けることを排除するものではない。
次に、図16を参照しつつ、電子機器2の作用・効果について説明する。
[変形例D]
図17は、図15の電子機器2の一変形例を表す。図17に記載の電子機器2では、表示パネル21の代わりに、表示パネル21の機能に加えて、さらに、非接触入力部30の機能も有する表示パネル23が設けられている。つまり、表示パネル23は、非接触入力部30を内蔵している。このとき、非接触入力部30は、光学プレート22に向かって非可視光を出力し、出力した非可視光が物体で反射され、光学プレート22を透過して戻ってきた光を検出することにより、非接触入力を受け付ける。つまり、非接触入力部30は、光学プレート22を透過して光の戻り光を検出することにより、非接触入力を受け付ける。これにより、非接触入力部30を別固に設けた場合よりも、非接触入力部30を省略できた分だけ筐体50を小型化することができる。また、非接触入力部30から出力される非可視光を外部に導く光路として、光学プレート22を使うことができるので、そのような光路を別途設けた場合よりも、筐体50を小型化することができる。また、表示パネル23から出射された非可視光が、映像200の生成される箇所に集まる(集光される)ので、映像200の生成される箇所での検出感度を向上させることができる。
