Abstract

The utility model relates to a liquid crystal display module field especially relates to a FPC buckles to distinguish to undercut and reduces stress structure. The utility model provides a FPC buckles to distinguish to undercut and reduces stress structure, including the flexible base plate of FPC, be equipped with buckle district, element region on the flexible base plate of FPC, the element region set up in the flexible base plate bottom of FPC, buckle the district set up in the flexible base plate top of FPC, the flexible base plate middle part silk screen printing of FPC has the location line of white, it undercuts the hole to buckle to distinguish to have seted up. The utility model discloses the region of buckling at the flexible base plate of FPC undercuts the processing, reduces its stress of buckling, effectively avoids functional bad that the bounce -back caused of buckling because of FPC.

Description

Reduction stress structure is emptied in a kind of FPC bent area

Technical field

The utility model relates to liquid crystal display module field, particularly relates to a kind of FPC bent area and empties reduction stress structure.

Background technology

At present in mobile phone display screen industry, the flexible circuit board used is folded into the back side of glass again after needing to press to above glass, and limit by handset structure, flexible circuit board needs the region of bending reduced, the stress of its bounce-back just becomes large, easily cause pressing position to rebound to disconnect, cause whole product function to lose efficacy.

Utility model content

The purpose of this utility model is for the deficiencies in the prior art, a kind of FPC bent area is provided to empty reduction stress structure, offer multiple tunneling hole in the bending region of FPC flexible base, board, reduce its bending stress, effectively avoid because of FPC bending bounce-back cause functional bad.

To achieve these goals, the technical solution adopted in the utility model is to provide a kind of FPC bent area and empties reduction stress structure, comprise FPC flexible base, board, described FPC flexible base, board is provided with bent area, element region, described element region is arranged at bottom described FPC flexible base, board, described bent area is arranged at described FPC flexible base, board top, and in the middle part of described FPC flexible base, board, the position line of silk-screen adularescent, described bent area offers tunneling hole.

As further improvement of the utility model, described tunneling hole is oval, and its top flushes with the broken line of described FPC flexible base, board bent area.

As further improvement of the utility model, described tunneling hole is at least eight.

As further improvement of the utility model, double faced adhesive tape is posted in described tunneling hole bottom.

As further improvement of the utility model, the thickness of described double faced adhesive tape is 0.05mm.

As further improvement of the utility model, the length of described element region is 10.5mm, and wide is 10mm.

The beneficial effects of the utility model are: the utility model carries out emptying process in the bending region of FPC flexible base, board, reduce its bending stress, effectively avoid because of FPC bending bounce-back cause functional bad.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

To illustrate below in conjunction with accompanying drawing and embodiment further illustrates the utility model.

Numeral in figure: 1, tunneling hole; 2, double faced adhesive tape; 3, the position line of white; 4, element region; 5, bent area.

The utility model know-why: at the bending region tunneling hole of FPC flexible base, board, reduce its bending stress, effectively avoid because of FPC bending bounce-back cause functional bad.

As shown in Figure 1, the utility model provides a kind of FPC bent area to empty reduction stress structure, comprise FPC flexible base, board, described FPC flexible base, board is provided with bent area 5, element region 4, described element region 4 is arranged at bottom FPC flexible base, board, described bent area 5 is arranged at described FPC flexible base, board top, and the position line 3 of silk-screen adularescent in the middle part of described FPC flexible base, board, described bent area 5 offers tunneling hole 1.Circuit is avoided in the position of tunneling hole 1, does not affect overall performance.

As shown in Figure 1, described tunneling hole 1 is oval, and its top flushes with the broken line of described FPC flexible base, board bent area 5.

As shown in Figure 1, described tunneling hole 1 is at least eight.

As shown in Figure 1, double faced adhesive tape 2 is posted in described tunneling hole 1 bottom.

As shown in Figure 1, the thickness of described double faced adhesive tape 2 is 0.05mm.

As shown in Figure 1, the length of described element region 4 is 10.5mm, and wide is 10mm.

Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection range of the present utility model.
