Abstract
An apparatus for fixing an optical film used in a back light to an outer frame of the back light. In the back light, a protrusion protrudes from a frame rim of the outer frame. A film extension extends from one side edge of the optical film and is placed on the surface of the frame rim near the protrusion. A clip is provided with a hole for inserting the protrusion to be mounted onto the frame rim such that the protrusion is inserted into the hole, thereby fixing the film extension of the optical film onto the frame rim.
Claims12
A back light of a liquid crystal display device including an outer frame provided with a frame rim surrounding edges of a light-conductive plate, and a first optical film installed in opposition to a light-emitting surface of the light-conductive plate, said back light comprising:
- a first protrusion protruding from a surface of the frame rim of the outer frame;
- a second protrusion protruding from an opposite surface of the frame rim as the surface from which the first protrusion protrudes;
- a first film extension extending from one side edge of the first optical film and placed on a surface of the frame rim near the protrusion;
- and
- a clip provided with a hole, wherein the first protrusion is inserted into the hole, and the clip is mounted onto the frame rim, fixing the first film extension of the optical film onto the frame rim.
A back light, comprising:
- a light-conductive plate;
- a clip having upper and lower holes;
- an outer frame having a lower and vertical protrusions and two holes adjacent said vertical protrusion;
- wherein said vertical protrusion has two perpendicular sidewalls, two angled sidewalls and a top surface;
- and
- optical films within said outer frame having two parallel extensions separated by an opening;
- wherein said parallel extensions are arranged within the holes;
- and
- wherein the optical films are secured to the outer frame by inserting the upper and lower protrusions of the outer frame through the upper and lower holes of the clip.
