Embodiment
Some embodiments of the present invention can be described in detail as follows.Yet except describing in detail, the present invention can also be widely implements at other embodiment, and scope of the present invention do not limited, and it is as the criterion with claim.
The material of flexible circuit board (soft board) is formed by macromolecule or polynary ester, owing to itself have pliability, be flexible its body to one predetermined extent and do not damage P.e.c. and body on it, therefore main concept of the present invention is to become its longitudinal length to have retractility the shaped design of soft board, before overturning, soft board can not bear a pulling force, be fixed on the circuit board after making its longitudinal length extend, and can make its longitudinal length shorten apart from shortening and elastic force effect because of two ends in soft board upset back itself, to reduce the outstanding distance after soft board overturns, avoid the waste in space.Please refer to Fig. 4, it demonstrates the first embodiment of the present invention.As shown in the figure, the present invention makes concavo-convex dentation with the light source soft board, and (be example only among the figure, in fact then can become a plurality of continuous or discrete teeth) according to its Demand Design with a tooth, such shape is when being subjected to pulling force, and the situation after it elongates please refer to Fig. 5; Therefore, when former the design, can design shortlyer with its longitudinal length (size A), when engaging (Bonding) or welding (Soldering), with the light source soft board do not damage body and on the situation of P.e.c. under, elongate default required longitudinal length (size B, size B＞size A), be set to again and carry out combination on the circuit board.After the upset of light source soft board, because of two ends own apart from shortening and the relation of elastic force, make that longitudinal length at this moment is littler than size B, but all be fixed because of two ends, so the outstanding distance of light source soft board will be reduced, and has had rough identical outstanding distance with the panel soft board.
Light source soft board shape of the present invention is regardless of, and it can be as Fig. 6, and the second embodiment of the present invention and the 3rd embodiment shown in Figure 7; Every general geometric figure has flexible effect as long as can reach the longitudinal length of soft board, all belongs to the row of the present invention's application, so do not describe in detail one by one at this.Certainly, according to the demand in the design, those patterns also can be designed to a plurality of continuous or discrete figures respectively, or the combination of its various patterns.
In addition, the existing panel soft board upset processus aboralis that also might produce because of the difference of design takes place for the situation of light source soft board, only need this moment by above-mentioned theory, design its longitudinal length (size A) shorter when former the design the panel soft board, when engaging (Bonding) or welding (Soldering), with the panel soft board do not damage body and on the situation of P.e.c. under, elongate default required longitudinal length (size B, size B＞size A), be set to again and carry out combination on the circuit board.Upset rear panel soft board is because of the relation of two ends apart from shortening and elastic force own, make that the longitudinal length of this moment is little than size B, but,, and had rough identical outstanding distance with the light source soft board so the outstanding distance of panel soft board will be reduced because of two ends all are fixed.
Characteristics of the present invention mainly are to provide a kind of flexible circuit board that is applied in LCD MODULE; it not only can not cause the space waste of LCD MODULE as existing; the inconvenience that further causes the user to use; and only utilize the design of the pliability and the flexible circuit board shape of flexible circuit board itself; it because of having retractility, can be reached elastic force; and its gimmick of reaching is simple and easy; with low cost; be noted that; though the present invention is to be example to be applied in LCD MODULE; but other can use the shape that changes flexible circuit board, and the product that makes its longitudinal length have retractility is also included within protection scope of the present invention.
Even the present invention describes by enumerating several preferred embodiments, but the present invention is not limited to the embodiment that enumerated.Though the specific embodiment of before enumerating and narrating, apparently, other does not break away under the disclosed spirit, and the equivalence of being finished changes or modifies, and all should be included in the claim of the present invention.In addition, all other do not break away under the disclosed spirit, and other that finished is similar and approximate to be changed or modification, also includes in claim of the present invention.Should explain scope of the present invention with the widest definition simultaneously, to comprise all modifications and similar structures.
