Abstract
The invention discloses an LED (Light-Emitting Diode) backlight source, which is formed by a rubber frame, an LED lamp strip, a light guide plate and an FPC (Flexible Printed Circuit) connector, wherein the light guide plate is arranged in the rubber frame; the LED lamp strip is fixedly arranged between the LED lamp strip and the light guide plate through the PFC connector; a light-resisting oil film is coated on the back face of the PFC connector; a clamping groove is arranged in an edge frame of the rubber frame; a clamping hook is arranged at the outer edge of the light guide plate; and the clamping hook is matched with the clamping groove to clamp the light guide plate into the rubber frame. The LED backlight source replaces a light shielding film by coating the light-resisting oil film on the back face of the PFC connector; and the LED backlight source has the advantages of simple structure and convenience for assembling, simplifies a process route and realizes the effect of improving the quality by low cost.
Description
Technical field
The present invention relates to the area source field, be applied to industrial instruments, household digital, the products such as electrical equipment, automobile are specifically related to a kind of LED-backlit source.
Background technology
Referring to shown in Figure 1, traditional LED-backlit source structure is complicated, and assembling is complicated, and the manufacture craft route is loaded down with trivial details, the raising of the production cost that directly causes.
Summary of the invention
For overcoming deficiency of the prior art, the present invention aims to provide a kind of simple in structure, the LED-backlit source that production cost is low.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of LED-backlit source, it is comprised of a glue frame, a LED lamp bar, a LGP and a FPC connector, described LGP is arranged in the described glue frame, described LED lamp bar is fixed between described LED lamp bar and the described LGP by described PFC connector, and the back side of described PFC connector scribbles the resistance photo-oil membrane.
Further, be provided with draw-in groove in the frame of described glue frame, be provided with snap fit on the outward flange of described LGP, described snap fit cooperates with described draw-in groove described LGP is stuck in the described glue frame.
Compared with prior art, the present invention has following beneficial effect:
The back side of LED-backlit of the present invention source by the PFC connector scribbles the resistance photo-oil membrane and substituted photomask, and is simple in structure, easy to assembly, and process route is simplified, and realized the effect of the lifting of quality under the cost.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and cooperate accompanying drawing to describe in detail.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Accompanying drawing described herein is used to provide a further understanding of the present invention, consists of the application's a part, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not consist of improper restriction of the present invention.In the accompanying drawings:
Fig. 1 shows the explosive view in LED-backlit source in the prior art.
Fig. 2 is the explosive view in LED-backlit of the present invention source.

The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Referring to Fig. 2, shown in Figure 3, a kind of LED-backlit source, it is comprised of a glue frame 1, a LED lamp bar 2, a LGP 3 and a FPC connector 4, described LGP 3 is arranged in the described glue frame 1, described LED lamp bar 2 is fixed between described LED lamp bar 2 and the described LGP 3 by described PFC connector 4, and the back side of described PFC connector 4 scribbles the resistance photo-oil membrane.
Further, be provided with draw-in groove 101 in the frame of described glue frame 1, be provided with snap fit 301 on the outward flange of described LGP 3, described snap fit 301 cooperates with described draw-in groove 101 described LGP 3 is stuck in the described glue frame 1.
Reflection, diffusion and the shading diaphragm on glue frame, LGP, LGP surface will be removed in the LED-backlit source of the present embodiment in traditional LED-backlit source, the light-emitting area of the LGP 3 of the present embodiment and refraction and the reflecting surface of site are done optical treatment, utilize now advanced optical design software and accurate chemical etching to process the reflecting surface site that backlight occurs when lighting LED, utilize high-accuracy minute surface Electrical Discharge Machine to process the cloudy surface of exiting surface at exiting surface again, thereby obtain the positive phenomenon of eliminating the site.Described LGP 3 solved positive can see the site phenomenon after, utilize the snap fit 301 of LGP 3 to carry out corresponding equipment with the draw-in groove 101 of glue frame 1, namely obtained the respective outer side edges of two parts, and then assembling substitutes photomask through the FPC connector 4 of optimizing, the width design that is about to FPC is suitably widened, and then stamp the resistance ink of black and other colors at the back side of the FPC connector that is unkitted SMD, reach the purpose that substitutes the shading diaphragm.Namely obtained only having the LED-backlit source of four sections' compositions.
The above only is preferred case study on implementation of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
