Abstract
An improvement for an installation structure of a backlight flexible circuit board relates to a backlight, and comprises an outer frame, a light guide plate, a reflecting film, an installation base of a flexible circuit board, the flexible circuit board and a double faced adhesive tape, wherein the light guide plate is arranged in the outer frame, and the reflecting film is adhered to one side of the light guide plate; and the installation base of the flexible circuit board consists of one frame of the outer frame and an adhering plate which is arranged at the two ends of the frame, and the frame forming the installation base of the flexible circuit board and the adhering plate at the two ends of the frame face to one side of the reflecting film are attached to one adhering side of the double faced adhesive tape, and the flexible circuit board is attached to the other adhering side of the double faced adhesive tape. The utility model has the beneficial effects that: the whole contact sides of the flexible circuit board and the installation base are adhered by the double faced adhesive tape, so the protuberance which is caused by unstable adhering of the middle position of the flexible circuit board and the installation base is avoided, the light outlet of a light-emitting diode (LED) chip is kept to be on the same plane of the light inlet of the light guide plate, so the optical effect of the backlight is increased.
Description
Technical field
The utility model relates to backlight, relates in particular to the structure that backlight enclosure is installed soft-circuit board.
Background technology
At present, the adhesive tape that is used to paste FPC on the backlight is arranged on the two ends of glue frame, the centre position part of glue frame does not all have the corresponding setting adhesive tape, like this, the centre position of FPC does not just have and the glue frame is bonded together, cause the easy projection in FPC centre position, make after the projection of FPC centre position the light-emitting window of led chip and LGP light inlet not at grade, will make the LGP luminous zone produce hot spot like this.
The utility model content
The utility model is at the deficiencies in the prior art, aim to provide a kind of structure that FPC is installed on the backlight glue frame that improves, all paste double faced adhesive tape on the whole piece frame of glue frame and FPC, it is more firm to make FPC install on backlight glue frame.
The utility model is achieved through the following technical solutions: the improvement of backlight FPC mounting structure, comprise housing, LGP, reflectance coating, FPC mount pad, FPC and double faced adhesive tape, LGP is arranged in the housing, and reflectance coating fits in the one side of LGP; Described FPC mount pad is that a frame of housing and the pasting boards that is arranged on described frame two ends are formed; The pasting boards at the frame of described composition FPC mount pad and described frame two ends fits in a stickup face of double faced adhesive tape towards the one side of reflectance coating, and described FPC fits in another stickup face of double faced adhesive tape.
The beneficial effects of the utility model are: one, by at the pasting boards at the frame of forming the FPC mount pad and frame two ends a stickup face towards the one side applying double faced adhesive tape of reflectance coating, FPC is fitted in another stickup face of double faced adhesive tape, like this, just make the entire contact surface of FPC and mount pad all be cemented by double faced adhesive tape, the mode that FPC is installed with present backlight compares, avoided not cause projection because cement between FPC centre position and the mount pad, make the light-emitting window of led chip and the light inlet of LGP keep at grade, strengthened the optical effect of backlight; Two, the utility model is simple in structure, with low cost remarkably productive.
Description of drawings
Fig. 1 is a Facad structure schematic diagram of the present utility model;
Fig. 2 is a reverse side structural representation of the present utility model.
Among the figure: 1, housing; 2, LGP; 3, reflectance coating; 4, FPC mount pad; 5, double faced adhesive tape.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further:
With reference to Figure 1 and Figure 2, the improvement of backlight FPC mounting structure, comprise housing 1, LGP 2, reflectance coating 3, FPC mount pad 4, FPC and double faced adhesive tape 5, LGP 2 is installed in the framework of housing 1, and reflectance coating 3 fits in the one side of LGP 2; FPC mount pad 4 is formed with the pasting boards that is arranged on this edge frame two ends for a frame of housing 1; The pasting boards of forming the frame of FPC mount pad 4 and this edge frame two ends fits in a stickup face of double faced adhesive tape 5 towards the one side of reflectance coating 3, and FPC fits in another stickup face of double faced adhesive tape 5.
In actual application, by at the pasting boards at the frame of forming FPC mount pad 4 and frame two ends a stickup face towards the one side applying double faced adhesive tape 5 of reflectance coating 3, FPC is fitted in another stickup face of double faced adhesive tape 5, like this, just make the entire contact surface of FPC and FPC mount pad 4 all be cemented by double faced adhesive tape 5, the mode that FPC is installed with present backlight compares, avoided not cause projection because cement between FPC centre position and the FPC mount pad 4, make the light-emitting window of led chip and the light inlet of LGP 2 keep at grade, strengthened the optical effect of backlight.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
Claims (1)
