Description

Fern-sprechgerStTelephone device

Die Erfindung betrifft ein Fernsprechgerät nach dem Oberbegriff des Anspruchs,The invention relates to a telephone device according to the preamble of the claim,

Lin derartiges Fernsprechgerät ist beispielsweise aus dem DE-GM 82 25 067 bekannt, das eine Kontrollvorrichtung mit einer Ziffernanzeige betrifft, wobei letztere gemäß einer Ausgestaltung von einer Flüssigkristallanzeige gebildet wird.A telephone device of this type is known, for example, from DE-GM 82 25 067, which relates to a control device with a numerical display, the latter being formed by a liquid crystal display according to one embodiment.

Außerdem sind Fernsprechgeräte mit an der Oberfläche angebrachten Bedienelementen und Solarzellen bekannt, bei denen die Solarzellen auf die nicht für Bedienelemente beanspruchten Teile der Oberfläche des Gerätes verteilt sind. Bei einer Abwandlung sind anstelle der Solarzellen lichtdurchlässige Oberflächen oder Sammellinsen vorgesehen, die das Licht auf im Innern des Gerätes befindliche Solarzellen leiten (DE-GM 82 28 867) .In addition, telephone devices with surface-mounted control elements and solar cells are known, in which the solar cells are distributed over the parts of the device's surface that are not used for control elements. In a modification, instead of solar cells, translucent surfaces or collecting lenses are provided that direct the light to solar cells located inside the device (DE-GM 82 28 867).

Der Erfindung Liegt die Aufgabe zugrunde, die SoLarzeLLen so anzuordnen, daß sie neben ihrer Funktion aLs Stromerzeuger noch eine weitere Funktion ausüben können. GeLöst wird diese Aufgabe durch die im Anspruch angegebenen MerkmaLe. Die Lösung hat den VorteiL, daß die SoLarzeLLe pLatzsparend, unauffäLLig und geschützt unter einer vorhandenen FLüssigkristaLLanzeige im Gerät angebracht ist, wo sie -vigLeich aLs LichtrefLexschicht für Letztere benutzbar is..The invention is based on the task of arranging the solar cells in such a way that they can perform another function in addition to their function as power generators. This task is solved by the features specified in the claim. The solution has the advantage that the solar cell is installed in a space-saving, unobtrusive and protected manner under an existing liquid crystal display in the device, where it can also be used as a light-reflecting layer for the latter.

Die Erfindung wird an einem AusführungsbeispieL näher erLäutert, das in der zugehörigen Zeichnung dargesteLLt ist. Die Figur zeigt eine erfindungsgemäße SoLarzeLLenanordnung in einem Gerät mit einer FLüssigkristaLLanzeigevorrichtung im Querschnitt.The invention is explained in more detail using an exemplary embodiment shown in the accompanying drawing. The figure shows a solar cell arrangement according to the invention in a device with a liquid crystal display device in cross section.

In dem Gerätgehäuse 1 ist ein durch eine GLaspLatte 2 verschLossener Ausschnitt 3 angebracht. Unter der GLaspLatte 2 befindet sich eine FLüssigkristaLLanzeige (LCD) 4, die für HintergrundbeLeuchtung geeignet ist. UnmitteLbar unter dieser FLüssigkristaLLanzeige 4 ist eine SoLarzeLLe 5 angeordnet, die sowohL die Funktion einer Li cht ref Lexschi cht für die F LUssi gkri sta'. La-zei ge aLs auch die Funktion einer StromqueLLe ausübt.In the device housing 1 there is a cutout 3 closed by a glass plate 2. Underneath the glass plate 2 there is a liquid crystal display (LCD) 4, which is suitable for background lighting. Immediately beneath this liquid crystal display 4 there is a solar cell 5, which performs both the function of a light-reflecting layer for the liquid crystal display and the function of a power source.
