ProjektionseinrichtungProjection device
Die Neuerung betrifft eine Projektionseinrichtung für auf einem flachen durchsichtigen Träger angeordneten Graphiken od.dgl..The innovation concerns a projection device for graphics or similar arranged on a flat, transparent carrier.
Es ist bekannt als Träger für Graphiken od.dgl. durchsichtige Folien zu verwenden und auf Projektionseinrichtungen mit ebener Arbeitsplatte, sogenannten Overheadpro j ektoren zum Einsatz zu bringen. Die Verwendung von Folien als Träger der Graphiken od.dgl. zeigt sich dabei als arbeitsaufwendig und ermöglicht nur starre Projektionen. Ferner sind zur Kenntlichmachung von Detials der projizierten Graphiken od.dgl. Zeigestäbe oder Lichtstrahlgeräte erforderlich.It is known to use transparent foils as a carrier for graphics or similar and to use them on projection devices with a flat work surface, so-called overhead projectors. The use of foils as a carrier for graphics or similar proves to be labor-intensive and only allows for rigid projections. In addition, pointers or light beam devices are required to identify details of the projected graphics or similar.
Aufgabe der Neuerung ist die Schaffung von Maßnahmen zur wahlweisen Darstellung starrer oder beweglicher Graphiken od.dgl. unter Verwendung von Overheadprojektoren.The aim of the innovation is to create measures for the optional display of fixed or moving graphics or similar using overhead projectors.
Der Neuerung gemäß ist diese Aufgabe dadurch gelöst, daß der Träger der Graphiken od.dgl. durch einen lichtdurchlässigen Flüssigkristallbildschirm gebildet ist, der auf einer im Projektionsstrahlengang eines Overheadpro j ektors angeordneten durchscheinenden oder durchsichtigen ebenen Arbeitsplatte auflegbar und mit dem Rechner eines Computers, Laptops oder Notebooks verbunden ist. Bevorzugt kann der Flüssigkristallbildschirm durch ein um die Kontrastplatte vermindertes Display eines Laptops oder Notebooks gebildet sein. Auf diese Weise ist die Projektion starrer oder beweglicher Graphiken od.dgl. möglich, wobei die Graphiken od.dgl. vom Rechner beliebig veränderbar sind. Die bekannte Benutzung einer Viel-According to the innovation, this task is solved in that the carrier of the graphics or the like is formed by a translucent liquid crystal screen that can be placed on a translucent or transparent flat work surface arranged in the projection beam path of an overhead projector and is connected to the computer of a computer, laptop or notebook. Preferably, the liquid crystal screen can be formed by a display of a laptop or notebook reduced by the contrast plate. In this way, the projection of fixed or moving graphics or the like is possible, whereby the graphics or the like can be changed as desired by the computer. The known use of a multi-
zahl Folien, z.B. zu Vorträgen oder Präsentationen entfällt, was auch zu einem Fortfall von umweltbelastendem Folienmüll führt. Die Projektion kann in schwarz/weiß oder farbig erfolgen.number of slides, e.g. for lectures or presentations, is no longer required, which also means that environmentally harmful slide waste is eliminated. The projection can be in black and white or color.
In Ausgestaltung der Projektionseinrichtung ist vorgesehen, daß der Flüssigkristallbildschirm und der Rechner durch flexible elektrische Leiter miteinander verbunden sind. Auch ist es möglich den Flüssigkristallbildschirm und den Rechner in anderer Weise, z.B. durch Infrarotstrahlung miteinander in Verbindung zu bringen.In the design of the projection device, it is intended that the liquid crystal screen and the computer are connected to one another by flexible electrical conductors. It is also possible to connect the liquid crystal screen and the computer in another way, e.g. by infrared radiation.
Schließlich ist eine umständliche Benutzung von Zeigestäben zur Hervorhebung von Details der projizierten Graphik od.dgl. dadurch unnötig, daß Details durch die Anzeige der Maus oder des Trackballs des Rechners erkennbar gemacht werden können.Finally, the cumbersome use of pointers to highlight details of the projected graphics or the like is unnecessary because details can be made visible by the display of the mouse or the trackball of the computer.
Wie die Neuerung ausführbar ist, zeigt das in der Zeichnung dargestellte Ausführungsbeispiel. Hierin bedeuten:The example shown in the drawing shows how the innovation can be implemented. The following means:
Fig. 1 einen Laptop mit einem Rechner und einem Flüssigkristallbildschirm aufweisenden Display in perspektivischer Darstellung undFig. 1 a laptop with a computer and a liquid crystal display in perspective view and
Fig. 2 eine Projektionseinrichtung, perspektivisch.Fig. 2 a projection device, perspective.
In den Fig. ist mit 1 der Rechner eines Laptops 2 oder Notebooks bezeichnet, an dem ein Display 3 schwenkbeweglich abnehmbar angeordnet ist. Das Display 3 weist einen Flüssigkristallbildschirm 4 auf, der durch eine abnehmbare Kontrastplatte hintergriffen ist.In the figures, 1 denotes the computer of a laptop 2 or notebook, on which a display 3 is arranged in a pivoting and removable manner. The display 3 has a liquid crystal screen 4, which is supported by a removable contrast plate.

In Fig. 2 ist das Display 3 vom Rechner 1 abgenommen und die Kontrastplatte des Displays 3 vom Flüssigkristallbildschirm 4 entfernt. Der auf diese Weise von beiden Seiten lichtdurchlässige Flüssigkristallbildschirm 4 ist auf die Arbeitsplatte 5 eines Overheadprojektor 6 aufgelegt· Mit seinem Anschlußrahmen 41 ist der Flüssigkristallbildschirm 4 durch elektrische Leiter 7 mit dem Rechner 1 des Laptops 2 oder Notebooks verbunden. Die auf dem Flüssigkristallbildschirm 4 erscheinenden Graphiken 10 od.dgl. können nunmehr vermittels der optischen Einrichtung des Overheadprojektor 6 über einen Umlenkspiegel 8 auf eine Bildfläche 9 projiziert werden. Vermittels des Rechners 1 ist die Graphik od.dgl. auf dem Flüssigkristallbildschirm veränderbar, wodurch eine hohe Flexibilität in der Vorführung von Graphiken od. dgl., z.B. zu Vorträgen erzielbar ist. Außerdem besteht die Möglichkeit, vermittels des Zeigers einer Maus oder eines Trackballs (nicht gezeigt) des Rechners 1 Anzeigen zur Verdeutlichung von Details auf dem Flüssigkristallbildschirm aufzubringen, die durch Projektion auf der Bildfläche 9 erscheinen.In Fig. 2, the display 3 has been removed from the computer 1 and the contrast plate of the display 3 has been removed from the liquid crystal screen 4. The liquid crystal screen 4, which is thus transparent from both sides, is placed on the worktop 5 of an overhead projector 6. The liquid crystal screen 4 is connected to the computer 1 of the laptop 2 or notebook by its connection frame 4 1 via electrical conductors 7. The graphics 10 or the like appearing on the liquid crystal screen 4 can now be projected onto a screen 9 by means of the optical device of the overhead projector 6 via a deflecting mirror 8. The graphics or the like on the liquid crystal screen can be changed by means of the computer 1, which allows a high degree of flexibility in the presentation of graphics or the like, e.g. for lectures. It is also possible to use the pointer of a mouse or a trackball (not shown) of the computer 1 to display details on the liquid crystal screen which appear by projection on the image surface 9.
