Abstract
The utility model discloses a flexible circuit board used for connecting a touch screen and a liquid crystal module. The flexible circuit board comprises a touch screen connecting terminal and a liquid crystal module connecting terminal. The width of the touch screen connecting terminal is larger than the width of the liquid crystal module connecting terminal. A transition connecting portion is formed between the touch screen connecting terminal and the liquid crystal module connecting terminal. The width of the transition connecting portion gradually increases from the liquid crystal module connecting terminal to the touch screen connecting terminal. The flexible circuit board has a simple structure, and can effectively avoid the damage to the flexible circuit board in bending.
Description
Technical field
The utility model relates to a kind of Flexible Printed Circuit, relates in particular to a kind of Flexible Printed Circuit for connecting touch-screen and Liquid Crystal Module.
Background technology
As everyone knows, progress along with science and technology, the input mode of mobile phone has developed into now from traditional keyboard formula input and has directly inputted by touch-screen, and the touch-screen after the key of realization touch input then is to assemble and Liquid Crystal Module be transmission information normally.Along with the development of electron trade, industry competition is also more and more fierce, and for the competitiveness of improving product, the monnolithic case of product certainly will be to lighter less thinner development, and the space that corresponding touch-screen occupies in whole product also reduces gradually.Consider the factors such as cost and space, what touch-screen and Liquid Crystal Module adopted is the mode that bends with Flexible Printed Circuit, connection in design trends of the times necessary guarantee Flexible Printed Circuit is normal, in case because the Flexible Printed Circuit fracture will directly cause the interruption of information, just mean that also the touch-input function of touch-screen will lose efficacy.
But between the Liquid Crystal Module link of present Flexible Printed Circuit and the touch-screen link without transition, but the width of touch-screen link is again greater than the Liquid Crystal Module link, as shown in Figure 1, this just makes and forms the right angle transient mode between the two, this Flexible Printed Circuit is when bending, and the impact that is easy to be subjected to external force and space is and impaired, and concentrate owing to reaching by bending stress the bending place simultaneously, the hidden danger that exists wiring board to be torn, thus cause touch-screen to lose efficacy.
Summary of the invention
In order to overcome defects, the utility model provides a kind of Flexible Printed Circuit for connecting touch-screen and Liquid Crystal Module, and this Flexible Printed Circuit is simple in structure, can effectively avoid Flexible Printed Circuit impaired when bending.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of Flexible Printed Circuit for connecting touch-screen and Liquid Crystal Module, this Flexible Printed Circuit comprises touch-screen link and Liquid Crystal Module link, the width of described touch-screen link is greater than the width of described Liquid Crystal Module link, between described touch-screen link and Liquid Crystal Module link, also be formed with the transition connecting portion, and the width of this transition connecting portion from described Liquid Crystal Module link to described touch-screen link increases gradually.
The beneficial effects of the utility model are: form a transition connecting portion between the touch-screen link by making Flexible Printed Circuit and the Liquid Crystal Module link, and the width of this transition connecting portion from described Liquid Crystal Module link to described touch-screen link increases gradually, thereby make the right angle transient mode of traditional touch-screen link and Liquid Crystal Module link change the hypotenuse transient mode into, effectively disperse the stress lifting surface area of junction, thereby avoid Flexible Printed Circuit impaired when bending.
Description of drawings
Fig. 1 is existing Flexible Printed Circuit structural representation;
Fig. 2 is Flexible Printed Circuit structural representation described in the utility model.
Embodiment
By reference to the accompanying drawings, the utility model is elaborated, but protection range of the present utility model is not limited to following embodiment.
As shown in Figure 2, a kind of Flexible Printed Circuit for connecting touch-screen and Liquid Crystal Module, this Flexible Printed Circuit comprises touch-screen link 1 and Liquid Crystal Module link 2, the width of described touch-screen link is greater than the width of described Liquid Crystal Module link, between described touch-screen link and Liquid Crystal Module link, also be formed with transition connecting portion 3, and the width of this transition connecting portion from described Liquid Crystal Module link to described touch-screen link increases gradually.Like this, this flexible circuit board can increase stressed area by this transition connecting portion when bending, and it is stressed to reduce bending, thereby impaired when avoiding bending.
