The technical solution of the present invention will be further described with reference to the following embodiments and the accompanying drawings.
Referring to fig. 1 to 4, an embodiment of the present invention provides a flexible touch screen, where the flexible touch screen 1 includes a conductive layer and a flexible protection layer 11, the conductive layer is provided with a circuit, the flexible protection layer 11 is attached to the conductive layer to cover all or part of the circuit, and the material of the flexible protection layer 11 is a flexible polymer material.
The flexible protective layer 11 is made of flexible polymer materials, and the flexible protective layer is made of the following materials: when the conductive layer is bent, the flexible protective layer 11 can also be bent along with the bending of the conductive layer. When the conductive layer is restored to the initial state (unbent state), the flexible protective layer 11 can also be restored to the initial state following the conductive layer.
Through scribble the flexible protective layer 11 that has high ductility, strong holding power, resistant buckling on the conducting layer on flexible touch screen 1 or adhesion one deck, can be when buckling flexible touch screen 1, can provide effectual protection and supporting role for flexible touch screen 1's circuit, the resistant bending nature of reinforcing flexible touch screen 1 avoids appearing the circuit fracture or cracked condition when flexible touch screen 1 is buckled many times in succession.
Specifically, the flexible polymer material may be polyethylene terephthalate (PET), Polyimide (PI), Polycarbonate (PC), polymethyl methacrylate (PMMA), polypropylene (PP), cyclic olefin copolymer (COC/COP), or a derivative thereof.
Wherein the thickness of the flexible protective layer 11 is 1 μm to 200 μm. For example: the thickness of the flexible protective layer 11 is 1 μm, 10 μm, 30 μm, 60 μm, 80 μm, 120 μm, 160 μm, 180 μm, 200 μm, or the like.
Since the thickness of the flexible protection layer 11 is very small, the increase of the thickness of the flexible touch screen 1 is very little, and thus the light and thin design of the flexible touch screen 1 can be satisfied.
Taking polyethylene terephthalate as an example of the polymer material, the flexible protection layer 11 may be a film or a coating layer that is made of a polymer material and is adhered or coated on the conductive layer by film imprinting, spin coating, blade coating, spray coating, slit coating, printing, sputtering, or vapor deposition, and the like, and can cover all or part of the circuit, so as to protect and support the circuit.

In addition, when the polymer material is adhered or coated on the conductive layer by spraying, slit coating, sputtering or evaporation and the like, the gaps between the lines on the conductive layer can be filled with the polymer material to form a smooth plane, so that the refractive index of light passing through the flexible touch screen 1 is reduced, the transmittance of the flexible touch screen 1 can be increased, the atomization degree of the flexible touch screen 1 can be reduced, and the optical performance of the flexible touch screen 1 can be enhanced.
In this patent, the flexible touch screen 1 can be applied to electronic devices such as a mobile phone, a tablet computer, a touch notebook computer, an intelligent wearable device (e.g., an intelligent watch), or a digital camera. For example: when the utility model discloses a flexible touch screen 1 is used for the cell-phone (like the collapsible cell-phone that appears on the market), can laminate flexible touch screen 1 on the surface of cell-phone, then the utility model discloses a flexible touch screen 1 can be the touch screen of cell-phone.
In this embodiment, the conductive layer includes a visible region 1a and a non-visible region, the circuit includes a first circuit 1c disposed in the visible region 1a and a second circuit 1d disposed in the non-visible region, and the second circuit 1d is electrically connected to the first circuit 1 c. The non-visual area can be divided into a first part 1b and a second part 1e extending outwards from one end of the first part 1b, the second circuit 1d is arranged on the first part 1b, the second part 1e is provided with a circuit interface 1f connected with a flexible circuit board of the flexible touch screen, and the circuit interface 1f is connected with the second circuit 1 d.
As an alternative embodiment, as shown in fig. 3, the flexible protection layer 11 may be disposed on the surface of the visible area 1a to completely cover the first circuit 1c, so that when the flexible touch screen 1 is bent, the first circuit 1c disposed on the visible area 1a can be effectively protected and supported, and thus the first circuit 1c can be prevented from being broken or cracked when the flexible touch screen 1 is continuously bent for multiple times.
As another alternative, as shown in fig. 2, the flexible protection layer 11 may be disposed on the surface of the non-visible region, that is, the flexible protection layer 11 may be disposed on the surface of the first portion 1b of the non-visible region to completely cover the second wire 1d, so that when the flexible touch screen 1 is bent, an effective protection and support effect can be provided for the second wire 1d disposed on the first portion 1b of the non-visible region, and thus, the second wire 1d can be prevented from being broken or cracked when the flexible touch screen 1 is continuously bent for multiple times.
As still another alternative, as shown in fig. 4, the flexible protection layer 11 may be disposed on the surfaces of the visible region 1a and the non-visible region at the same time, that is, the flexible protection layer 11 may be disposed on the surfaces of the visible region 1a and the first portion 1b of the non-visible region at the same time to completely cover the first wire 1c and the second wire 1d, so that when the flexible touch screen 1 is bent, an effective protection and support effect can be provided for the first wire 1c and the second wire 1d, and thus, the first wire 1c and the second wire 1d can be prevented from being broken or cracked when the flexible touch screen 1 is bent for multiple times.
It can be known that the non-visible region is generally disposed around the periphery of the visible region 1a, wherein the non-visible region is not bent relative to the visible region 1a (as shown in fig. 1 to 4), the non-visible region is also bent relative to the visible region 1a, a bent portion 1g is formed at a connection position of the first portion 1b and the second portion 1e of the non-visible region, that is, a bent portion 1g is formed at a part of the second portion 1e, and a second line 1d is disposed at the bent portion, so that the second portion 1e of the non-visible region can be bent to the lower surface of the substrate layer 12 (as shown in fig. 5 and 6).
Since the flexible protection layer 11 is disposed on the surface of the non-visible area to completely cover the second circuit 1d, when the non-visible area is bent toward the lower surface of the visible area 1a (as shown in fig. 6), the bent portion 1g of the non-visible area has the tensile force and the supporting force of the flexible protection layer 11, so that the flexible display screen 1 can still protect the second circuit 1d disposed on the bent portion 1g of the non-visible area when the flexible display screen 1 is bent with a relatively small diameter.
It should be appreciated that when the flexible touch screen 1 of the present invention is used in a mobile phone (such as a foldable mobile phone appearing on the market), the flexible touch screen 1 can be attached to the surface of the display module of the mobile phone through the optical adhesive, and an adhesion layer 15 is formed between the surface of the display module of the mobile phone and the substrate layer 12 at this time.
