TRANSPARENT ACTIVE FRAME FOR A DISPLAY USING A LIGHT GUIDING FOIL

摘要

A device comprising a transparent plate (TP) and a light guiding foil (LGF). A light source (LS) supplies light into the light guiding foil (LGF) so as to provide light, preferably visible light, from a surface (S) of the light guiding foil (LGF) and emitted through the transparent plate (TP). In one embodiment, the light guiding foil (LGF) is laminated onto a plane glass plate (TP) which forms part of or forms the entire front of a device. Especially, the device is a display device, e.g. a TV set or monitor with a display panel (DP), where the light guiding foil (LGF) is used to provide a transparent lighting frame or rim around an image area (IA) of the display panel (DP). With the use of a light reflector (R), it is possible to provide light also from the border or bezel area (B) of the display panel (DP), and thus provide a seamless transition between the transparent lighting frame or rim and the image area (IA) of the device.
