Abstract

The background lighting panel has an inlet on the side [11] and two outlets [12,13] one of which has a film [14] that reflects a mix of P and S light [104], while the transmitted light [105] is of only P type. On either side are liquid crystal display panels [21,22] that have polarising plates [211,221]. The brightness of the lower panel is improved.

1. Hintergrundbeleuchtungsmodul mit Lichtabgabe nach zwei Seiten, zwischen zwei Flüssigkeitskristallanzeigemodulen eingebaut, mit:
zumindest einer Lichtquelle;
einer lichtleitenden Platte, die eine Seite mit einer Lichteintrittsfläche hat, be­ nachbart der Lichtquelle, und die zwei parallele Flächen aufweist, die jeweils eine erste Lichtaustrittsfläche und/oder eine zweite Lichtaustrittsfläche haben, jeweils be­ nachbart zu der Lichteintrittsfläche, so dass eine Lichtquelle für jedes der beiden Flüssigkeitskristallmodule vorgesehen ist; und
zumindest einem Helligkeitsverbesserungsfilm, der zwei axiale Lichtstrahlen trennen kann, so dass ein axialer Lichtstrahl durch den Helligkeitsverbesserungsfilm hindurch tritt und der andere axiale Lichtstrahl von dem Helligkeitsverbesserungsfilm reflektiert wird, wobei der Helligkeitsverbesserungsfilm an entweder der ersten Licht­ austrittsfläche oder der zweiten Lichtaustrittsfläche der lichtleitenden Platte montiert ist, so dass die Helligkeit der Flüssigkeitsanzeigemodule mittels des Helligkeitsver­ besserungsfilms verbessert wird.1. Backlight module with light emission on two sides, installed between two liquid crystal display modules, with:
at least one light source;
a light-guiding plate, which has a side with a light entry surface, be adjacent to the light source, and which has two parallel surfaces, each having a first light exit surface and / or a second light exit surface, each be adjacent to the light entry surface, so that a light source for each the two liquid crystal modules are provided; and
at least one brightness enhancement film that can separate two axial light rays, so that one axial light ray passes through the brightness enhancement film and the other axial light ray is reflected by the brightness enhancement film, the brightness enhancement film being mounted on either the first light exit surface or the second light exit surface of the light-conducting plate , so that the brightness of the liquid display modules is improved by means of the brightness improvement film. 2. Hintergrundbeleuchtungsmodul mit Lichtabgabe nach zwei Seiten gemäß An­ spruch 1, wobei der Helligkeitsverbesserungsfilm aus PCF ist.2. Backlight module with light emission on two sides in accordance with An saying 1, wherein the brightness enhancement film is made of PCF. 3. Hintergrundbeleuchtungsmodul mit Lichtabgabe nach zwei Seiten gemäß An­ spruch 1, wobei der Helligkeitsverbesserungsfilm aus DBEF ist. 3. Backlight module with light emission on two sides in accordance with An saying 1, wherein the brightness improvement film is made of DBEF.   4. Hintergrundbeleuchtungsmodul mit Lichtabgabe nach zwei Seiten gemäß An­ spruch 1, wobei die andere Fläche von der ersten Lichtaustrittsfläche oder der zwei­ ten Lichtaustrittsfläche der lichtleitenden Platte ebenfalls mit einem Helligkeitsverbes­ serungsfilm versehen ist, so dass nach der Reflexion des Lichtes zwischen den bei­ den Helligkeitsverbesserungsfilmen das gesamte Licht von der Lichtquelle in ein Licht transformiert wird, dessen optische Achsenrichtung mit den beiden Flüssigkeitskri­ stallanzeigemodulen übereinstimmt, wodurch die Helligkeit der Flüssigkeitskristallan­ zeigemodule verbessert ist.4. Backlight module with light emission on two sides according to an saying 1, the other surface being from the first light exit surface or the two th light exit surface of the light-guiding plate also with a brightness verb is provided so that after the reflection of the light between the two the brightness enhancement films all the light from the light source into one light is transformed, its optical axis direction with the two liquid crystals stall display modules matches, causing the brightness of the liquid crystal Show modules is improved. 5. Hintergrundbeleuchtungsmodul mit Lichtabgabe nach zwei Seiten gemäß An­ spruch 4, wobei der Helligkeitsverbesserungsfilm aus PCF ist.5. Backlight module with light emission from two sides according to An Proverb 4, where the brightness enhancement film is made of PCF. 6. Hintergrundbeleuchtungsmodul mit Lichtabgabe nach zwei Seiten gemäß An­ spruch 4, wobei der Helligkeitsverbesserungsfilm aus DBEF ist.6. Backlight module with light emission from two sides according to An Proverb 4, where the brightness enhancement film is made of DBEF.
