Description
Technical field
The present invention relates to a kind of flexible printing circuit board fixing structure, the fixed sturcture of the glue frame of particularly a kind of flexible printed wiring board and LCD backlight module.
Background technology
Thin Film Transistor-LCD (Thin Film Transistor-Liquid Crystal Display, TFT-LCD) have advantages such as low consumpting power, thin type light weight and low voltage drive, so be the most general present a kind of flat-panel screens, be widely used in electronic products such as notebook computer, desktop computer and LCD TV.
Usually, LCD panel of thin-film transistor (Panel) is by a thin film transistor (TFT) (Thin FilmTransistor, TFT) array base palte and a colorized optical filtering (Color Filter, CF) substrate combines, liquid crystal is filled between tft array substrate and the CF substrate.Because TFT-LCD can not be luminous voluntarily, thus the light source that need provide image to show by module backlight, and transmit voltage signal via driving circuit and control liquid crystal and the penetrability of light source is obtained suitable image show.
The LCD of small-medium size is owing to stressing frivolous and reducing cost, so liquid crystal module is not often had a metal backing, therefore the bottom surface of module backlight is reflector plate, also all immobilization material aspect mechanism with the double faced adhesive tape, the reflector plate inner face is fixed with its peripheral attaching double faced adhesive tape and glue frame, and generally at flexible printed wiring board (Flexible Printed Circuit, fixing FPC), bottom the optical mode group that often the FPC turnover supported or opposed, and with double faced adhesive tape fixedly FPC in module backlight bottom surface, Figure 1A is the assembling schematic perspective view before FPC and module backlight bottom surface do not adhere to, Figure 1B is that FPC and module backlight bottom surface are adhered fixed the schematic perspective view after finishing, reflector plate 202 is positioned at bottom and its surface of the glue frame 20 of module backlight and posts double faced adhesive tape 204, FPC10 has main part 102, kink 104 and portion of terminal 106, kink 104 after bending in order to electrically connect a LCD panel (not shown), and portion of terminal 106 is fixed on the reflector plate 202 with double faced adhesive tape 204 after FPC 10 turnovers in order to electrically connect an a connector or a circuit board (not shown).
Though the position of double faced adhesive tape and shape can optionally change, most double faced adhesive tape all can be attached on the reflector plate, so will cause two unevennesses of bad phenomenon: 1.FPC own and the myotatic reflex sheet make its protuberance, make that the optical quality of display is bad; 2.FPC bending stress excessive, and the adhesive power between reflector plate and glue frame is sinkd beneath one's burden, and reflector plate is dug by related, thereby causes the reliability of display bad.
Summary of the invention
Paste FPC with double faced adhesive tape and on reflector plate, cause the reflector plate protuberance or dig in order to solve prior art, so that cause the optical quality and the bad problem of reliability of display, the invention provides a kind of FPC fixed sturcture of LCD backlight module.
Paste FPC on reflector plate so that the thicker problem of display thickness in order to solve prior art with double faced adhesive tape, the invention provides a kind of FPC fixed sturcture of LCD backlight module, lack the thickness of a slice double faced adhesive tape than prior art, can effectively reduce the dimensional thickness of display.
One of purpose of the present invention provides a kind of FPC fixed sturcture, and the teat of FPC is thinner than main part, in order to reduce the bending stress after teat bends, prevents that bending stress from causing the distortion of FPC protuberance.
One of purpose of the present invention provides a kind of FPC fixed sturcture, and the side groove of glue frame is a fillet corresponding to the corner of FPC teat bending place, is beneficial to the bending of FPC teat and reduces bending stress.
One of purpose of the present invention provides a kind of FPC fixed sturcture, utilizes double faced adhesive tape to adhere in the side groove of glue frame with fixing FPC after the bending of the teat of FPC.
One of purpose of the present invention provides a kind of FPC fixed sturcture, and the bending part of the teat of FPC has at least one through hole and forms the roulette effect to reduce bending stress, makes the FPC after the attaching keep smooth.
One of purpose of the present invention provides a kind of FPC fixed sturcture, and the side groove at the glue frame is provided with trip and corresponding hole is set at teat respectively, and teat bending back is fastened in hole in the trip of groove with fixing FPC.
One of purpose of the present invention is to provide different FPC fixed sturctures at different FPC structures, when the portion of terminal of FPC is relative with its kink, FPC has at least one teat respectively on the both sides adjacent with kink, when the portion of terminal of FPC is adjacent with its kink, one side FPC is at the have at least one teat relative with kink.
Therefore, FPC fixed sturcture of the present invention can improve the optical quality and the reliability of LCD, and reaches the purpose that makes LCD thickness thinner.
In order to achieve the above object, one embodiment of the invention provide a kind of FPC fixed sturcture of LCD backlight module, comprise: the glue frame of a module backlight, and its side has at least one groove; And a FPC, the glue frame that it is fixed in module backlight comprises: a main part; One side one kink is itself and being connected of main part; And at least one teat, it is connected with main part and it is fixed in the groove of glue frame after bending.
