Abstract

In a display with an LCD-screen (2) and a light box (1) arranged behind the LCD-screen (2), several luminescent diodes (5-7) with the primary colours are arranged in the light box (1). The luminescent diodes (5-7) can be switched by a driving unit (3) at the same time as individual segments (4) of the LCD-screen (2) which correspond to picture elements of a picture. Any desired coloured images can thus be displayed on the LCD-screen (2). By switching the luminescent diodes (5-7) and LCD-screen (2) for a particularly short time, images which seem multicoloured to the human eye are produced.

Description

Die Erfindung betrifft eine Anzeigevorrichtung zur Anzei­ ge von farbigen Bildern mit einem LCD-Bildschirm, welcher mehrere in ihrem Transmissionsvermögen schaltbare, ein­ zelnen Bildpunkten zugeordnete Segmente aufweist, mit ei­ nem hinter dem LCD-Bildschirm angeordneten, zur Durch­ leuchtung des LCD-Bildschirms mittels mehrerer Lichtquel­ len ausgebildeten Lichtkasten und mit einer Ansteuerein­ heit zum Ansteuern der Segmente und der Lichtquellen.The invention relates to a display device for display of colored images with an LCD screen, which several switchable in their transmissivity has individual segments assigned segments, with egg nem arranged behind the LCD screen, for through Illumination of the LCD screen using multiple light sources len trained light box and with a control unit to control the segments and the light sources.

Solche Anzeigevorrichtungen werden zur Anzeige in vielen Geräten eingesetzt und sind damit bekannt. Die Segmente des LCD-Bildschirms stellen einzelne Bildpunkte dar, aus denen die Bilder zusammengesetzt sind. Die farbige Dar­ stellung der Bilder wird häufig dadurch erreicht, daß hinter dem LCD-Bildschirm ein Farbfilter angeordnet ist. Die Anzeigevorrichtung eignet sich damit beispielsweise zum Darstellen von Bildern wie Warnhinweise, Stadtpläne oder Zustandsinformationen in einem Kraftfahrzeug. Such display devices are used for display in many Devices used and are therefore known. The segments of the LCD screen represent individual pixels of which the pictures are composed. The colored dar Position of the pictures is often achieved in that a color filter is arranged behind the LCD screen. The display device is therefore suitable, for example to display images such as warnings, city maps or status information in a motor vehicle.  

Nachteilig bei der bekannten Anzeigevorrichtung ist, daß der Farbfilter einen hohen Anteil des von den Lichtquel­ len abgestrahlten Lichts absorbiert. Dies führt zu einem hohen Strombedarf für die Lichtquellen und zu hohen Tem­ peraturen in dem Lichtkasten.A disadvantage of the known display device is that the color filter has a high proportion of that from the light source len absorbed light absorbed. This leads to one high power requirements for the light sources and excessive tem temperatures in the light box.

Der Erfindung liegt das Problem zugrunde, eine Anzeige­ vorrichtung der eingangs genannten Art so zu gestalten, daß sie möglichst kostengünstig herstellbar ist und hohe Temperaturen im Lichtkasten vermeidet.The invention is based on the problem of an advertisement to design the device of the type mentioned at the beginning that it is as inexpensive to manufacture and high Avoid light box temperatures.

Dieses Problem wird erfindungsgemäß dadurch gelöst, daß für jede Grundfarbe zumindest eine Lichtquelle vorgesehen ist und daß die Ansteuereinheit zum Zusammensetzen des farbigen Bildes aus den Grundfarben durch ein aufeinan­ derfolgendes Ansteuern der die einzelnen Grundfarben er­ zeugenden Lichtquellen zeitgleich mit den der jeweiligen Grundfarbe zugeordneten Segmenten ausgebildet ist.This problem is solved according to the invention in that at least one light source is provided for each basic color and that the control unit for assembling the colored image from the primary colors by one on top of the other the following control of the individual primary colors generating light sources simultaneously with those of the respective Basic color assigned segments is formed.

Durch diese Gestaltung läßt sich eine Vielzahl von Bil­ dern durch die Anzeigevorrichtung in verschiedenen Farben ohne den Einsatz eines Farbfilters im Lichtkasten dar­ stellen. Durch die zeitgleiche und aufeinanderfolgende Ansteuerung der jeweils eine der Farben aufweisenden Lichtquellen und der der jeweiligen Farbe zugeordneten Segmente des LCD-Bildschirms wird das farbige Bild nach­ einander aus einem roten, einem blauen und einem gelben Bild zusammengesetzt. Durch die Trägheit des menschlichen Auges erscheint das Bild für einen Betrachter der Anzei­ gevorrichtung farbig. Dadurch, daß kein Farbfilter zur farbigen Durchleuchtung des LCD-Bildschirms benötigt wird, gelangt ein besonders großer Anteil des von den Lichtquellen erzeugten Lichts zu dem Betrachter. Bei gleicher vorgesehener Helligkeit der Anzeigevorrichtung können damit im Vergleich zum Stand der Technik weniger oder schwächere Lichtquellen eingesetzt werden. Die An­ zeigevorrichtung heizt sich deshalb weniger stark auf. Durch den Wegfall des Farbfilters ist die Anzeigevorrich­ tung besonders kostengünstig herstellbar.This design allows a large number of images the display device in different colors without the use of a color filter in the light box put. Through the simultaneous and successive Control of one of the colors Light sources and those assigned to the respective color Segments of the LCD screen will follow the colored image each other out of a red, a blue and a yellow Composed image. Due to the sluggishness of the human The picture appears to a viewer of the advertisement device colored. Because no color filter colored fluoroscopy of the LCD screen is required a particularly large proportion of the Light sources generated light to the viewer. At the same intended brightness of the display device can do less compared to the prior art or weaker light sources are used. The An  The pointing device therefore heats up less. By eliminating the color filter, the display device is tion can be produced particularly cost-effectively.

Die Anzeigevorrichtung eignet sich gemäß einer vorteil­ haften Weiterbildung der Erfindung zur Anzeige von ste­ henden oder bewegten Bildern wie für Warnhinweise, wenn die Frequenz der Ansteuerung der Lichtquellen und der Segmente durch die Ansteuereinheit veränderbar ist. Für eine Darstellung eines für das menschliche Auge flimmer­ freien stehenden oder bewegten Bildes ist eine möglichst hohe Frequenz erforderlich. Zur Anzeige von Warnhinweisen kann die Frequenz verringert und damit ein flimmerndes, die Aufmerksamkeit eines Betrachters erregendes Bild er­ zeugt werden. Hierdurch eignet sich die erfindungsgemäße Anzeigevorrichtung besonders für einen Einsatz in einem Kraftfahrzeug oder in einer Überwachungsanlage.The display device is suitable according to one advantage adhere to the invention to display ste moving or moving pictures as for warnings, if the frequency of the control of the light sources and the Segments can be changed by the control unit. For an illustration of a flicker for the human eye Free standing or moving picture is one if possible high frequency required. To display warnings can reduce the frequency and thus a flickering, a viewer's attention-grabbing image be fathered. As a result, the invention is suitable Display device especially for use in one Motor vehicle or in a surveillance system.

Ein dauerhafter Betrieb der Lichtquellen führt nur zu ei­ nem unwesentlichen Aufheizen des Lichtkastens, wenn die Lichtquellen gemäß einer anderen vorteilhaften Weiterbil­ dung der Erfindung von Leuchtdioden gebildet sind. Die Leuchtdioden sind für die drei Grundfarben verfügbar, so daß sich der LCD-Bildschirm mit beliebigen Farben durch­ leuchten läßt. Weiterhin haben die Leuchtdioden den Vor­ teil, eine besonders geringe Trägheit beim Schalten auf­ zuweisen.Continuous operation of the light sources only leads to egg insignificant heating of the light box when the Light sources according to another advantageous development tion of the invention are formed by light emitting diodes. The LEDs are available for the three primary colors, see above that the LCD screen with any color lights up. Furthermore, the LEDs have the front partly, a particularly low inertia when switching on to assign.

Die Anzeigevorrichtung benötigt gemäß einer anderen vor­ teilhaften Weiterbildung der Erfindung besonders wenige Lichtquellen, wenn die Leuchtdioden als Mehrchip- Leuchtdioden ausgebildet sind. Durch diese Gestaltung sind besonders wenige Lichtquellen erforderlich, da jede der Leuchtdioden zur Erzeugung einer beliebigen Farbe ausgebildet ist. The display device needs another according to partial development of the invention particularly few Light sources if the LEDs as multi-chip LEDs are formed. Through this design very few light sources are required since each the LEDs to produce any color is trained.  

Anzeigevorrichtungen mit einer besonders großen Hellig­ keit sind gemäß einer anderen vorteilhaften Weiterbildung der Erfindung kostengünstig herstellbar, wenn die Licht­ quellen als Neonröhren ausgebildet sind.Display devices with a particularly large brightness speed are according to another advantageous development the invention inexpensive to manufacture when the light sources are designed as neon tubes.
