Abstract
Description
Die Erfindung bezieht sich auf Anordnungen zur wahlweise zwei- oder dreidimensional wahrnehmbaren Darstellung.The The invention relates to arrangements for either two- or three-dimensional perceptible representation.
Eine
solche Anordnung beschreibt unter anderem die
Es ist nun Aufgabe der Erfindung, eine Anordnung der eingangs genannten Art zu schaffen, die mit möglichst geringem Aufwand zu fertigen ist. Weiterhin soll die wahlweise zwei- oder dreidimensional wahrnehmbare Darstellung in etwa mit gleicher Helligkeit dargeboten werden.It Now is an object of the invention, an arrangement of the aforementioned To create the kind of way possible little effort to manufacture. Furthermore, the optional two- or three-dimensional perceptible representation approximately with the same Brightness be presented.
Diese Aufgabe wird erfindungsgemäß gelöst von einer Anordnung zur wahlweise zwei- oder dreidimensional wahrnehmbaren Darstellung, mindestens umfassend:
- – einen ersten Bildschirm zur mindestens zeitweise hilfsmittelfrei räumlich wahrnehmbaren Darstellung,
- – einen zweiten Bildschirm zur Darstellung zweidimensional wahrnehmbarer Bilder, der in seiner Bildflächennormalenrichtung vor dem ersten Bildschirm angeordnet ist, wobei
- – die erfindungsgemäße Anordnung in mindestens zwei Modi betreibbar ist und im ersten Modus auf dem ersten Bildschirm hilfsmittelfrei räumlich wahrnehmbare Bildinformation wiedergegeben und der zweite Bildschirm so transparent wie möglich geschaltet wird und im zweiten Modus der erste Bildschirm mindestens auf einer Teilfläche, bevorzugt jedoch ganzflächig, ein homogenes helles, weißes Bild wiedergibt, während der zweite Bildschirm mindestens auf einer Teilfläche zweidimensionale Bildinformation anzeigt.
- A first screen for at least temporarily aid-free spatially perceptible presentation,
- A second screen for displaying two-dimensionally perceptible images arranged in front of the first screen in its image area normal direction, wherein
- - The arrangement according to the invention is operable in at least two modes and displayed in the first mode on the first screen tool-free spatially perceivable image information and the second screen is switched as transparent as possible and in the second mode, the first screen at least on a partial surface, but preferably over the entire surface homogeneous bright white image while the second screen displays at least a partial area two-dimensional image information.
Somit wird gewissermaßen im ersten Modus durch den zweiten Bildschirm hindurch auf die 3D-Darstellung des ersten Bildschirms geblickt, während im zweiten Modus der erste Bildschirm quasi als Hintergrundbeleuchtung des zweiten Bildschirms dient.Consequently becomes, so to speak in the first mode through the second screen to the 3D representation of the first Screen looked while in the second mode, the first screen as a kind of backlight the second screen is used.
Die zwei Bildschirme befinden sich bevorzugt in geringem Abstand (wenige Millimeter bis Zentimeter) oder gar in engem Kontakt miteinander, um möglichst keine Bildvignettierung des ersten Bildschirmes auf Grund des zweiten Bildschirmes zu erzeugen. Beide Bildschirme können auch unterschiedliche Abmaße aufweisen.The two screens are preferably located at a small distance (a few Millimeters to centimeters) or even in close contact with each other, as possible no image vignetting of the first screen due to the second Generate screen. Both screens can also be different dimensions exhibit.
Bevorzugt ist der erste Bildschirm, welcher z.B. ein LC-Display ist, permanent zur räumlich wahrnehmbaren Darstellung geeignet und hierzu beispielsweise mit einem Filterarray, einem Lentikular, einem Barriereschirm und/oder einem holografisch-optischen Element ausgerüstet.Prefers is the first screen which is e.g. an LC display is permanent to the spatially perceptible representation suitable and this example with a filter array, a lenticular, a barrier screen and / or equipped with a holographic-optical element.
Bei dem zweiten Bildschirm, durch welchen im ersten Modus auf den ersten Bildschirm zur räumlich wahrnehmbaren Darstellung geblickt wird, kann es sich beispielsweise um ein LC-Display-Panel (ohne Hintergrundbeleuchtung) oder ein Elektrolumineszenzdisplay handeln. Im ersteren Falle sollte im zweiten Modus der erste Bildschirm bevorzugt ein flächig weißes Bild darstellen, um den zweiten Bildschirm von hinten zu beleuchten. Im zweiten Falle, d.h. bei Verwendung eines Elektrolumineszenzdisplays als zweiter Bildschirm, ist dies nicht notwendig. Dann nämlich ist der zweite Bildschirm selbstleuchtend und benötigt keinerlei Hintergrundbeleuchtung.at the second screen, through which in the first mode on the first Screen for spatial For example, it may look like perceptible representation around a LC display panel (without backlight) or an electroluminescent display act. In the former case, the second screen should have the first screen prefers a flat white picture to illuminate the second screen from behind. In the second case, i. when using an electroluminescent display as a second screen, this is not necessary. Then that is the second screen is self-luminous and does not require any backlighting.
Vorzugsweise sind bei der erfindungsgemäßen Anordnung noch elektronische Mittel zur Ansteuerung der mindestens zwei Bildschirme vorhanden. Hierbei handelt es sich um handelsübliche Ansteuerelektroniken, beispielsweise um solche, wie sie für LC-Displays üblich sind.Preferably are in the inventive arrangement still electronic means for controlling the at least two screens available. These are commercially available control electronics, for example, those that are common for LC displays.
Die in Rede stehende Anordnung kann auch noch zwischen dem ersten und zweiten Bildschirm eine schaltbare Streuscheibe enthalten, die im ersten Modus transparent und im zweiten Modus streuend geschaltet ist und welche der Homogenisierung des von dem ersten Bildschirm abgestrahlten Lichtes im zweiten Modus dient.The The arrangement in question can still be between the first and the last second screen contain a switchable diffuser that is in the the first mode is transparent and switched to the second mode is and what the homogenization of the first screen emitted light in the second mode is used.
Weitere Komponenten, wie z.B. zusätzliche erste oder zweite Bildschirme, können vorgesehen sein. Entscheidend für das erfinderische Wirkprinzip der Anordnung ist die Umschaltbarkeit zwischen den vorstehend beschriebenen ersten und zweiten Modi zur wahlweise zwei- oder dreidimensional wahrnehmbaren Darstellung.Further Components, e.g. additional first or second screens, can be provided. Decisive for the inventive principle of the arrangement is the switchability between the above-described first and second modes for optionally two- or three-dimensional perceptible representation.
Die Erfindung wird im folgenden an Hand von Zeichnungen näher erläutert.The Invention will be explained in more detail below with reference to drawings.
