Abstract

Mobile data processing device such as a laptop has a translucent cover that forms a back projection system in conjunction with a projection unit.

Description

Die Erfindung betrifft eine mobile Datenverarbeitungs- Einrichtung. The invention relates to a mobile data processing Facility.

Eine solche Einrichtung ist beispielsweise ein Laptop oder ein Notebook oder einer der kleineren Varianten wie ein PDA (Personal Digital Assistent). Such a device is for example a laptop or a notebook or one of the smaller versions like a PDA (Personal Digital Assistant).

Zur Darstellung der Informationen werden heutzutage bei Laptops Flachbildschirme verwendet. Die Herstellung dieser Bildschirme ist aufwendig und teuer und erhöht dadurch den Preis des Endgerätes wesentlich. Nowadays, the information is presented at Laptops used flat screens. The making of this Screens are complex and expensive and thereby increase the price of the end device essential.

Der Erfindung liegt die Aufgabe zugrunde diese Nachteile zu beseitigen. The object of the invention is to overcome these disadvantages remove.

Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch angegebenen Merkmale gelöst. This object is achieved by the im Characteristics specified solved.

Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles beschrieben. In the following, the invention is illustrated in the drawing illustrated embodiment described.

In der einzigen Figur ist ein Laptop LP als Beispiel für eine mobile Datenverarbeitungs-Einrichtung dargestellt. Normalerweise besitzen Laptops LP einen als Flachbildschirm ausgebildeten Deckel. In the single figure, a laptop LP is an example of one mobile data processing device shown. Laptops LP usually have one as a flat screen trained lid.

Erfindungsgemäß weist der Laptop LP einen transluzenten Deckel PF auf. In an sich bekannter Weise dient dieser Deckel PF im zusammengeklappten Zustand des Endgerätes als Schutz für die Tastatur. An der Rückseite des Laptops LP ist weiter eine Projektionseinheit PE angeordnet. Diese Projektionseinheit PE ist beispielsweise an einem beweglichen Arm befestigt, der in das Gerät selbst hineingeschoben werden kann. Es sind hierbei auch schwenkbare Varianten möglich. Innerhalb des Arms laufen die Datenleitungen und die Spannungsversorgung für die Projektionseinheit PE. According to the invention, the laptop LP has a translucent Cover PF open. This cover serves in a manner known per se PF in the folded state of the end device as protection for the keyboard. At the back of the laptop LP is further a projection unit PE is arranged. This The projection unit PE is on a movable arm, for example attached, which can be pushed into the device itself. It swiveling versions are also possible. Within of the arm the data lines and the Power supply for the projection unit PE.

Die Projektionseinheit PE besteht selbst beispielsweise aus einem Microdisplay, einem LED-Array zur Beleuchtung und einer Optik. Die Projektionseinheit PE projiziert das Bild von hinten auf die transluzente Fläche beziehungsweise den Deckel PF. In Verbindung mit der Projektionseinheit PE bildet die Projektionsfläche PF ein sogenanntes Rückprojektionssystem. The projection unit PE itself consists of, for example a microdisplay, an LED array for lighting and one Look. The projection unit PE projects the image from on the back of the translucent surface or the lid PF. In conjunction with the projection unit PE, the Projection area PF is a so-called rear projection system.

Die erfindungsgemäße Lösung mit der Rückprojektion ermöglicht im Vergleich zu einer Frontprojektion einen für den Betrachter günstigeren Winkel der Projektionsfläche PF. The solution according to the invention with the rear projection enables compared to a front projection one for the Observer more favorable angle of the projection surface PF.
