Description
Die Erfindung betrifft ein Anzeigegerät gemäß Oberbegriff von Anspruch 1.The invention relates to a display device according to the preamble of claim 1.
Es sind Anzeigegeräte bekannt, welche zur Erfassung der Annäherung eines Körpers, wie beispielsweise einer Hand, geeignet sind und dafür Infrarotemittereinheiten und Photozellen aufweisen.Display devices are known which are suitable for detecting the approach of a body, such as a hand, and for this purpose have infrared emitter units and photocells.
Der Erfindung liegt die Aufgabe zu Grunde ein Anzeigegerät vorzuschlagen, welches relativ flach bzw. dünn bzw. kompakt ausgebildet werden kann und/oder welches relativ kostengünstig ist.The invention is based on the object of proposing a display device which can be made relatively flat or thin or compact and / or which is relatively inexpensive.
Diese Aufgabe wird erfindungsgemäß gelöst durch das Anzeigegerät gemäß Anspruch 1.This object is achieved according to the invention by the display device according to claim 1.
Unter der Erfassung einer Annäherung eines Körpers wird vorzugsweise die Erfassung einer Position und/oder Bewegung eines Körpers verstanden, wobei dieser Körper insbesondere eine Hand oder ein Teil einer Hand oder ein Hilfsbedienelement, wie beispielsweise ein Stift ist.The detection of an approach of a body is preferably understood to mean the detection of a position and / or movement of a body, this body in particular being a hand or part of a hand or an auxiliary operating element such as a pen.
Unter der Sichtschicht wird bevorzugt eine transparente Schutzschicht bzw. Frontschicht bzw. Bildschirmscheibe verstanden, insbesondere aus Glas.The visual layer is preferably understood to mean a transparent protective layer or front layer or screen pane, in particular made of glass.
Die Infrarotemittereinheiten und die Photozellen sind bevorzugt auf der von der Sichtschicht abgewandten Fläche der Anzeigeschicht angeordnet oder alternativ vorzugsweise in der Anzeigeschicht integriert bzw. eingebettet.The infrared emitter units and the photocells are preferably arranged on the surface of the display layer facing away from the viewing layer or, alternatively, preferably integrated or embedded in the display layer.
Durch eine Anordnung auf der von der Sichtschicht abgewandten Fläche der Anzeigeschicht emittieren die Infrarotemittereinheiten ihre Infrarotwellen durch die Anzeigeschicht hindurch.The infrared emitter units emit their infrared waves through the display layer through an arrangement on the surface of the display layer facing away from the visible layer.
Es ist bevorzugt, dass die Infrarotemittereinheiten und Photozellen jeweils voneinander beabstandet, insbesondere hinsichtlich der benachbarten Einheiten gleichmäßig voneinander beabstandet, und insbesondere abwechselnd, angeordnet sind, besonders bevorzugt entlang einer Linie und/oder eines Musters. Hinsichtlich der abwechselnden Anordnung wird besonders bevorzugt verstanden, dass abwechseln entlang einer Linie bzw. Geraden durch das Muster Infrarotemittereinheiten und Photozellen abwechselnd angeordnet sind. Hierdurch kann ein besonders homogenes Feld zur Erfassung erreicht werden. Unter dem Begriff Einheiten werden insbesondere die Infrarotemittereinheiten und Photozellen gemeinsam bezeichnet.It is preferred that the infrared emitter units and photocells are each spaced apart from one another, in particular evenly spaced from one another with regard to the neighboring units, and in particular alternately, particularly preferably along a line and / or a pattern. With regard to the alternating arrangement, it is particularly preferably understood that infrared emitter units and photocells are alternately arranged along a line or straight line through the pattern. In this way, a particularly homogeneous field for detection can be achieved. The term units in particular denotes the infrared emitter units and photocells together.
Es ist zweckmäßig, dass die Infrarotemittereinheiten und Photozellen so angeordnet sind, dass sie im Wesentlichen ein Netz aufspannen und/oder auf den Kreuzungspunkten eines Rastermusters angeordnet sind, wobei diese Kreuzungspunkte insbesondere äquidistant voneinander entfernt sind und, insbesondere abwechselnd, mit Infrarotemittereinheiten und Photozellen besetzt sind.It is expedient that the infrared emitter units and photocells are arranged in such a way that they essentially span a network and / or are arranged on the intersection points of a grid pattern, these intersection points in particular being equidistant from one another and, in particular, alternately occupied by infrared emitter units and photocells .
Es ist bevorzugt, dass zwischen Sichtschicht und Anzeigeschicht eine optisch durchsichtige bzw. klare Verbindungsschicht angeordnet ist. Zweckmäßigerweise ist diese Verbindungsschicht im Wesentlichen aus einer Bondschicht, insbesondere einem Bondwafer, und/oder einer Klebeschicht, ausgebildet. Besonders bevorzugt ist die Verbindungsschicht mit der Sichtschicht und/oder der Anzeigeschicht formschlüssig und/oder stoffschlüssig verbunden.It is preferred that an optically transparent or clear connecting layer is arranged between the viewing layer and the display layer. This connection layer is expediently formed essentially from a bond layer, in particular a bond wafer, and / or an adhesive layer. Particularly preferably, the connection layer is connected to the viewing layer and / or the display layer in a form-fitting and / or material-locking manner.
Zweckmäßigerweise sind die Infrarotemittereinheiten als Infrarot-LEDs ausgebildet, also als Infrarotlicht bzw. -wellen emittierende Leuchtdioden.The infrared emitter units are expediently designed as infrared LEDs, that is to say as light-emitting diodes that emit infrared light or waves.
Die Infrarotemittereinheiten sind vorzugsweise so angeordnet, dass sie im Wesentlichen ein homogenes Emissionsfeld von Infrarotwellen im Außenbereich der Oberfläche des Bildschirms erzeugen.The infrared emitter units are preferably arranged in such a way that they essentially generate a homogeneous emission field of infrared waves in the outer region of the surface of the screen.
Bevorzugt sind die Infrarotemittereinheiten so ausgebildet, dass diese Infrarotwellen sequentiell gepulst erzeugen/ emittieren. Insbesondere emittieren die Infrarotemittereinheiten entlang einer Reihe und/oder gemäß einer geordneten Struktur in dem Muster ihrer Anordnung nacheinander die Infrarotwellen, wodurch deren emittierte Infrarotwellen besonders bevorzugt einen Phasen- und/oder Zeitversatz relativ zueinander aufweisen. Dadurch werden die räumliche Erfassung bzw. Positionserfassung eines annähernden Körpers verbessert.The infrared emitter units are preferably designed in such a way that they generate / emit infrared waves sequentially in a pulsed manner. In particular, the infrared emitter units emit the infrared waves one after the other along a row and / or according to an ordered structure in the pattern of their arrangement, whereby their emitted infrared waves particularly preferably have a phase and / or time offset relative to one another. This improves the spatial detection or position detection of an approaching body.
Die Beleuchtungsschicht umfasst bevorzugt LCD- und/oder LED-Elemente und ist so ausgebildet, dass sie insbesondere die Anzeigeschicht durchleuchtet und damit die Helligkeit des Bilds, welches das Anzeigegerät anzeigt, bereitstellt.The lighting layer preferably comprises LCD and / or LED elements and is designed in such a way that it in particular shines through the display layer and thus provides the brightness of the image which the display device displays.
Das Anzeigegerät ist zweckmäßigerweise als Instrumentenanzeigegerät und/oder Navigationsanzeigegerät eines Kraftfahrzeugs ausgebildet.The display device is expediently designed as an instrument display device and / or navigation display device of a motor vehicle.
