Abstract
Description
Die Erfindung betrifft ein LCD-Display, wie es beispielsweise als Anzeigeelement bei einem Klimasteuergerät Anwendung findet.The The invention relates to an LCD display, such as, for example, as a display element at a climate control unit Application finds.
LCD-Displays weisen zwei übereinanderliegende Glasscheiben mit an diesen angeordneten transparenten Elektroden auf, wobei die beiden Glasscheiben längs ihrer Ränder abgedichtet sind und Flüssigkristalle in den so begrenzten Raum zwischen den beiden Glasplatten untergebracht sind. Mithin ist die Anzeigeseite eines LCD-Displays eben.LCD displays have two superimposed Glass sheets with arranged on these transparent electrodes with the two glass sheets sealed along their edges and liquid crystals housed in the so limited space between the two glass plates are. Thus, the display side of an LCD display is level.
In zunehmendem Maße geht man aus designerischen und optischen Gründen dazu über, die Anzeigeflächen von LCD-Displays in die Kontur der des LCD-Displays umgebenden Baugruppen zu legen. So ist es beispielsweise wünschenswert, dass die Anzeigefläche eines LCD-Displays der geschwungenen Form der Instrumententafel eines Fahrzeuges folgt. Ein LCD-Display würde grundsätzlich auch dann arbeiten, wenn die die Flüssigkristalle einschließenden Glasplatten gewölbt sind. Die Herstellung derartiger LCD-Displays ist jedoch extrem aufwendig und nahezu unmöglich, da über die gesamte Anzeigefläche ein gleichbleibender Abstand beider Glasplatten gewährleistet sein muss.In increasing one goes out for designischen and optical reasons, the display areas of Lay LCD displays in the contour of the LCD display surrounding assemblies. So For example, is it desirable to that the display area an LCD display of the curved shape of the instrument panel a vehicle follows. An LCD display would basically work even then when the liquid crystals inclusive Arched glass panels are. However, the production of such LCD displays is extreme complicated and almost impossible over there the entire display area ensures a constant distance between the two glass plates have to be.
Bisher geht man daher dazu über, das LCD-Display mit seiner Anzeigeseite gegenüber der geschwungenen Kontur der Instrumententafel rückgesetzt anzuordnen, um in die sich so ergebende Vertiefung eine (Kunststoff-)Abdeckscheibe einzusetzen, die der Kontur der Instrumententafel folgt. Diese Abdeckscheibe ist transluzent (beispielsweise Rauchglas-Immitation).So far So you go to the LCD display with its display side opposite the curved contour the instrument panel reset to order, in the resulting depression a (plastic) cover that follows the contour of the instrument panel. This cover is translucent (for example smoked glass immitation).
Für ein ansprechendes optisches Design ist es wünschenswert, wenn sich bei der zuvor beschriebenen Konstellation die einzelnen Symbole des LCD-Displays als in der gewölbten Oberfläche der Abdeckscheibe liegend darstellen würden. Mit anderen Worten ist es wünschenswert, wenn die Anzeigeseite des LCD-Displays für den Betrachter als gewölbte Struktur erscheint.For an appealing optical design it is desirable if in the constellation described above, the individual Symbols of the LCD display as in the domed surface of the cover lying down. In other words, it is desirable if the display side of the LCD display for the Viewer as arched Structure appears.
Der Erfindung liegt die Aufgabe zugrunde, ein LCD-Display mit optisch verbesserter Anzeige zu schaffen, bei dem die Symbole als auf einer gewölbten Fläche liegend dargestellt sind.Of the Invention is based on the object, an LCD display with optical to provide improved display in which the symbols as on one domed area are shown lying.
Zur Lösung dieser Aufgabe wird mit der Erfindung ein LCD-Display vorgeschlagen, das versehen ist mit
- – einem LCD-Element, das eine ebene Anzeigeseite mit an dieser angeordneten transparenten Elektroden von Anzeigeelementen aufweist, und
- – einer transluzenten Abdeckscheibe, die bei Betrachtung der Anzeigeseite des LCD-Elements vor diesem angeordnet ist und eine dem LCD-Element abgewandte, insbesondere zylindrisch, ballig oder sphärisch vorgewölbte Außenseite aufweist,
- – wobei die Anzeigeelementelektroden im mittleren Bereich des LCD-Elements in einer Erstreckung gestreckter sind als die Anzeigeelemente im Bereich der quer zu dieser Erstreckung liegenden Enden des LCD-Elements.
- An LCD element having a planar display side with transparent electrodes of display elements disposed thereon, and
- A translucent cover pane, which is arranged in front of it when viewing the display side of the LCD element and has an outer side facing away from the LCD element, in particular cylindrical, spherically or spherically bulging outside,
- - Wherein the display element electrodes are stretched in the central region of the LCD element in an extension of the display elements in the region of lying transversely to this extension ends of the LCD element.
Nach der Erfindung sind die Anzeigesymbole des LCD-Displays im mittleren Bereich der Anzeigeseite gegenüber den Symbolen in den Endbereichen der Anzeigeseite verzerrt dargestellt. Insbesondere erfolgt dies durch eine Streckung der Anzeigesymbole in einer Richtung, die quer zu derjenigen Richtung verläuft, längs derer die zuvor genannten Enden des LCD-Elements angeordnet sind. Durch diese Verzerrung der Symbole, d. h. der verzerrten Struktur der Anzeigeelementelektroden, wird für den Betrachter der Eindruck erweckt, dass die Symbole auf der gewölbten (Außen-)Seite der Abdeckscheibe liegen.To the invention, the display symbols of the LCD display in the middle Area of the display page opposite The symbols in the end areas of the display page are distorted. In particular, this is done by an extension of the display symbols in a direction transverse to that direction along which the aforementioned ends of the LCD element are arranged. By this distortion of symbols, d. H. the distorted structure of the display element electrodes, is for gives the viewer the impression that the symbols are on the curved (outside) side lie the cover.
In vorteilhafter Weiterbildung der Erfindung ist vorgesehen, dass die Anzeigeelementelektroden im Bereich der Enden des LCD-Elements zu den Enden hin gewölbt verlaufen. Auch hierdurch verstärkt sich der Eindruck der Darstellung der Symbole auf einer gewölbten Fläche.In Advantageous development of the invention is provided that the Display element electrodes in the region of the ends of the LCD element arched towards the ends run. This also increases the impression of the representation of the symbols on a curved surface.
Ferner ist es zweckmäßig, wenn die Vorwölbung der Außenseite des Abdeckelements bezogen auf zwei senkrecht zueinander verlaufende Mittelachsen der Anzeigeseite des LCD-Elements symmetrisch ist, wobei die eine Mittelachse in Richtung der Streckung der Anzeigeelementelektroden im mittleren Bereich der Anzeigeseite verläuft.Further it is useful if the protrusion the outside the cover with respect to two perpendicular to each other Center axes of the display side of the LCD element is symmetrical, wherein the one central axis in the direction of extension of the display element electrodes in the middle area of the display page.
Die zuvor beschriebene Verzerrung der Symbolik des LCD-Displays kann auch dadurch realisiert werden, dass die Symbole in den Endbereichen des LCD-Elements gegenüber den Symbolen im mittleren Bereich gestaucht sind.The previously described distortion of the symbolism of the LCD display can also be realized by the symbols in the end regions of the LCD element across from the symbols in the middle area are compressed.
Wie sich aus dem Vorstehenden ergibt, wird erfindungsgemäß das Layout des LCD-Displays leicht verzerrt dargestellt. An den Enden sind die Symbole kleiner als die Symbole im mittleren Bereich. Die Abdeckscheibe wird vorzugsweise in ihrer Dicke bis kurz vor das LCD-Anzeigeelement gezogen, um einen Unterschied in der Farbe zu vermeiden. Beide Seiten der Abdeckscheibe sind gewölbt; alternativ kann die dem LCD-Element zugewandte untere Seite der Abdeckscheibe plan sein. Durch die Betrachtung der Außenseite der Abdeckscheibe wird mittels Täuschung dem Betrachter suggeriert, die Anzeige würde der Oberfläche folgen.As is apparent from the above, according to the invention, the layout of the LCD display is slightly distorted. At the ends the symbols are smaller than the symbols in the middle area. The cover is preferably pulled in its thickness until just before the LCD display element to avoid a difference in color. Both sides of the cover are curved; Alternatively, the LCD side facing lower side of the cover can be flat. By looking at the outside of the cover is suggested by deception to the viewer, the Ad would follow the surface.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert. Im einzelnen zeigen:The Invention will now be described with reference to an embodiment with reference closer to the drawing explained. In detail show:
