Abstract
The utility model relates to a FPC backlight assembly capable of preventing the shift of a bright enhancement film, which comprises a rubber-iron integrated rubber frame back plate and a light guide plate, and the backlight assembly also comprises a bright enhancement film arranged between the back surface of the light guide plate and the rubber frame back plate, and a FPC backlight source containing LED lamps is assembled at the bottom edge of the rubber frame back plate through a double-sided adhesive tape; two corners of the bottom of the bright enhancement film are respectively extended and formed with a first extending part which protrudes, correspondingly, two corners of the upper edge of the double-sided adhesive tape are respectively formed with a second extending part which protrudes from the upper edge of the FPC backlight source, and the second extending parts are overlapped and attached with the first extending parts of the bright enhancement film. The utility model discloses a set up outstanding extension respectively at the two-sided adhesive tape of membrane and equipment FPC backlight, make the extension of membrane and two-sided adhesive tape overlap the laminating together to form the bonding location, make the membrane of adding lustre to further fix a position and glue between frame backplate and light guide plate, avoid taking place the displacement phenomenon, further promote backlight unit's whole quality.
Description
The technical field is as follows:
the utility model relates to a cell-phone backlight unit technical field refers in particular to a can prevent FPC backlight unit that membrane that adds lustre to shifted.
Background art:
the existing backlight assembly of the mobile phone comprises a backlight source, a light guide plate, a brightness enhancement film, an FPC backlight source (FPC (flexible printed circuit board)) with an LED and a rubber frame backboard and other various parts for positioning the rubber and iron integrated type of the backlight source and the FPC, generally, the brightness enhancement film is arranged between the rubber frame backboard and the light guide plate, and in the prior art, the positioning of the brightness enhancement film is mainly realized by the accuracy of the internal size of the rubber frame backboard and the overall dimension of the brightness enhancement film and the cooperation of the light guide plate. The structure is still easy to generate the phenomena of micro displacement and the like of the brightness enhancement film, and finally influences the quality of the backlight assembly.
The utility model has the following contents:
the utility model aims at overcoming the weak point of existing equipment, provide a FPC backlight unit that can prevent the membrane that adds lustre to shift.
The utility model adopts the technical proposal that: a FPC backlight assembly capable of preventing a brightness enhancement film from shifting comprises a rubber frame back plate and a light guide plate which are integrated by rubber and iron, the backlight assembly further comprises a brightness enhancement film arranged between the back surface of the light guide plate and the rubber frame back plate, an FPC backlight source containing LED lamps is assembled at the edge of the bottom of the rubber frame back plate through a double-sided adhesive tape in a bonding mode, the FPC backlight source and the brightness enhancement film are located on the same side of the light guide plate, and the bottom of the brightness enhancement film is adjacent to the FPC backlight source; wherein: and correspondingly, two corners of the upper edge of the double-sided adhesive tape are respectively provided with a second extension part protruding from the upper edge of the FPC backlight source, and the second extension parts are overlapped and attached with the first extension parts of the bright enhancement film.
And the second extension part of the double-sided adhesive tape is bonded with the back of the light guide plate.
The utility model discloses a set up outstanding extension respectively at the two-sided adhesive tape of membrane and equipment FPC backlight, make the extension of membrane and two-sided adhesive tape overlap the laminating together to form the bonding location, make the membrane of adding lustre to further fix a position and glue between frame backplate and light guide plate, avoid taking place the displacement phenomenon, further promote backlight unit's whole quality.
Description of the drawings:
FIG. 1 is a schematic plan view of the backlight assembly of the present invention;
fig. 2 is an exploded schematic plan view of the backlight assembly of the present invention;
fig. 3 is a partially enlarged view of a portion a in fig. 1.
The specific implementation mode is as follows:
the present invention will be further described with reference to the following specific embodiments and accompanying drawings.
As shown in fig. 1-fig. 3, the present invention is a FPC backlight assembly capable of preventing the shift of the bright enhancement film, which includes a frame back plate 1 and a light guide plate 2 integrated with a rubber and iron, the backlight assembly further includes a bright enhancement film 3 disposed between the back of the light guide plate 2 and the frame back plate 1, an FPC backlight 5 containing LED lamps is assembled at the bottom edge of the frame back plate 1 by bonding with a double-sided adhesive tape 4, the FPC backlight 5 and the bright enhancement film 3 are disposed at the same side of the light guide plate 2, and the bottom of the bright enhancement film 3 is adjacent to the FPC backlight 5; wherein: two corners of the bottom of the brightness enhancement film 3 are respectively extended and formed with a first extending portion 31 protruding, correspondingly, two corners of the upper edge of the double-sided adhesive tape 4 are respectively formed with a second extending portion 41 protruding from the upper edge of the FPC backlight 5, and the second extending portions 41 are overlapped and attached with the first extending portion 31 of the brightness enhancement film 3.
The second extension 41 of the double-sided adhesive tape 4 is adhered to the back surface of the light guide plate 2. That is, one surface of the second extending portion 41 of the double-sided adhesive tape 4 is bonded to the first extending portion 31 of the brightness enhancement film 3, and the other surface is bonded to the back surface of the light guide plate 2.
The utility model discloses a set up outstanding extension respectively at the two-sided adhesive tape of membrane and equipment FPC backlight, make the extension of membrane and two-sided adhesive tape overlap the laminating together to form the bonding location, make the membrane of adding lustre to further fix a position and glue between frame backplate and light guide plate, avoid taking place the displacement phenomenon, further promote backlight unit's whole quality.
