Detailed Description
The invention is further illustrated by means of the following examples, which are not intended to limit the scope of the invention.
Example 1
The embodiment provides a touch screen module, referring to fig. 4, the touch screen module includes a first film layer 5, a bending region is disposed at an edge of the first film layer 5, and a first metal wiring region 521 is disposed on a surface of the bending region.
As an alternative embodiment, referring to fig. 4, the first film layer 5 includes a base layer and a metal wiring layer 502, the metal wiring layer 502 is disposed on an upper surface of the base layer, the base layer includes a body region 504 and an edge region 503, the metal wiring layer 502 includes a first metal wiring region 521, the first metal wiring region 521 is disposed on an upper surface of the edge region 503, and the first metal wiring region 521 and the edge region 503 together form a bending region. The bending region bends upward. Because the inflection region is upwardly inflection, the edge region 503 occupies less space in the horizontal direction than in the prior art, thereby facilitating making the bezel narrower to increase the screen duty cycle. The edge areas can be left and right edges of the first film layer, so that the left and right frames can be narrower; the edge area can also be the upper edge and the lower edge of the first film material layer, which is beneficial to making the upper frame and the lower frame narrower. In addition, when the complexity of the circuit is higher and more metal wires need to be routed, referring to fig. 4, the edge region 503 and the body region 504 form a folded structure, so that the size of the edge region of the first film layer is expanded in the existing space to accommodate more metal wires, and the circuit is adapted to the complex circuit. In order to accommodate the bending region, as shown in fig. 4, the lower surface of the cover plate 301 disposed on the top layer is provided with a caulking groove 311, and the bending region is embedded into the caulking groove 311. To fix the bending region, the lower surface of the edge region 503 is adhered to the bottom surface of the caulking groove 311 by an optical adhesive. The first film layer 5 is adhered to the lower portion of the cover plate 301 through the first optical adhesive layer 601. The LCM 304 is adhered to the lower portion of the first film layer 5 through the second optical adhesive layer 602.
Example 2
The embodiment provides a touch screen module, referring to fig. 5, the touch screen module includes, from top to bottom, a cover plate 301, a first optical adhesive layer 601, a second film layer 4, a second optical adhesive layer 602, a first film layer 5, a full-lamination optical adhesive layer 303, and an LCM 304.
The first film layer 5 includes a base layer and a metal wiring layer 502, the metal wiring layer 502 is disposed on an upper surface of the base layer, the base layer includes a body region 504 and an edge region 503, the metal wiring layer 502 includes a first metal wiring region 521, the first metal wiring region 521 is disposed on an upper surface of the edge region 503, and the first metal wiring region 521 and the edge region 503 together form a bending region. The bending region bends upward. The body region 504 is adhered to the lower portion of the second film layer 4 through the second optical adhesive layer 602. The LCM 304 is attached to the lower portion of the body region 504 by the full-lamination optical adhesive layer 303.
The first film material layer 5 is used as a driving layer of the touch screen module, and the second film material layer 4 is used as a sensing layer of the touch screen module. In order to save substrate material and provide more accommodation space for the edge region of the first film layer, referring to fig. 6, in this embodiment, the width of the second film layer 4 is smaller than that of the conventional sensing layer, and the second metal wiring region 402 on the upper surface of the second film layer 4 is not specially provided with a ground line, so that the width of the second film layer 4 is the same as that of the first window 401. Fig. 7 shows the structure in which the first film layer 5 is flattened (not yet bent) and has a wider width than the second film layer 4, and the first metal wiring area 502 on the upper surface of the first film layer 5 is not provided with a ground line exclusively. Referring to fig. 5 and 7, a second window 501 is disposed on the first film layer 5, and the second window 501 is disposed corresponding to the first window 401, and the dimensions of the second window are the same. In other optional embodiments, the second metal wiring area on the upper surface of the second film layer is provided with a ground wire, and the first metal wiring area on the upper surface of the first film layer is provided with a ground wire, and a specific arrangement manner of the ground wire is clear to those skilled in the art and is not described herein again.
As shown in fig. 5, two ends of the first film layer 5 are respectively bonded to the first optical adhesive layer 601, specifically, lower surfaces of two side edges of the substrate layer are respectively bonded to the first optical adhesive layer. The area formed by the first film layer 5 and the first optical adhesive layer 601 surrounds the second film layer 4 and the second optical adhesive layer 602. To maximize space utilization to accommodate more metal wires on the first film layer or to narrow the frame, the ends of the second film layer are joined to the ends of the first film layer as shown in fig. 5. Because the first film material layer 5 surrounds the second film material layer 4, the first film material layer 5 forms a shield for the outside for the second metal wiring area 402 on the upper surface of the second film material layer 4, and can shield electromagnetic interference of external signals, so that no special ground wire is arranged for the second metal wiring area 402, and less substrate material can be used, thereby reducing cost. Similarly, the substrate layer of the first film layer 5 wraps the first metal wiring area 502 inside, so that shielding is formed for the first metal wiring area 502 to the outside, and electromagnetic interference of external signals can be shielded, so that no special ground wire is arranged in the first metal wiring area 502, and more metal wires can be accommodated. In addition, the surrounding structure also enables the bonding seam between the first film material layer 5 and the second film material layer 4 to be wrapped, so that the bonding seam is not exposed to the outside and is not easy to be damaged by external force. Referring to fig. 5, the touch screen module further includes a housing 8, and the housing 8 is bonded to the bending region by an optical adhesive (not shown), specifically, the housing 8 is bonded to the lower surface (i.e., the opposite surface) of the edge region 503. Because the protection of above-mentioned surrounding structure, the optical cement of bonding department can not produce pressure to the bonding seam between first membrane material layer 5 and the second membrane material layer 4, and first membrane material layer 5 is difficult for peeling off with second membrane material layer 4, namely, drive layer is difficult for peeling off with the induction layer, therefore, the stability of this touch screen module is higher.
In the embodiment, the edge of the first film layer is bent, so that more metal wires are accommodated under the same frame size, and the touch device is suitable for more complex touch devices; or under the condition of the same size (same wiring quantity) of the first film material layer, the smaller frame size is occupied, and the screen occupation ratio of the touch equipment is improved.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the principles and spirit of the invention, but such changes and modifications fall within the scope of the invention.
