Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.

Example one

Fig. 2 is a schematic structural diagram of a flexible touch panel according to a first embodiment of the present invention, which includes a body 1 and a ground line disposed around the body 1, where the body 1 is made of a flexible material, and in this embodiment, the body 1 is made of a poly (p-phenylene terephthalate) Plastic (PET). The ground wire is provided with a first fracture 5, and the first fracture 5 divides the ground wire into a first ground wire 2 and a second ground wire 3. The first ground line 2 and the second ground line 3 are parallel to each other in the overlapping area a at the first discontinuity 5. The first ground line 2 or the second ground line 3 is provided with an antistatic portion 6 in an overlapping area a at the first discontinuity 5.

The body in the prior art is a rigid body, and the body develops towards flexibility along with upgrading and updating of products, and in the development process, an electrostatic discharge (ESD) phenomenon occurs due to the change of surface conductivity.

Through analysis, when the flexible touch panel passes through an extreme ultraviolet lithography (EUV) lamp tube 4 of an EUV apparatus, a potential difference is formed at the first fracture 5, so that an ESD phenomenon is caused. The static electricity preventing part 6 is arranged on the first ground wire 2 or the second ground wire 3 and in the overlapping area A of the first fracture 5, so that the ESD phenomenon can be effectively prevented, and the yield is improved.

As a specific implementation manner, in the first embodiment, the static electricity preventing portion 6 is an extension provided on one of the first ground line and the second ground line located on the inner side. As shown in fig. 2, in the present embodiment, the extension segment is disposed on the first ground 2, and the extension segment is disposed such that when the whole product passes through the EUV lamp 4, the first ground 2 and the second ground 3 almost simultaneously pass through the EUV lamp 4, thereby having an equipotential capability and avoiding the occurrence of the ESD phenomenon.

In this embodiment, the length of the extension is 1-1.5 mm. Whereas the overlapping length of the overlapping area in the prior art is 0.5-1mm, the length of the overlapping area a can reach 1.5-2.5mm, preferably 2mm, by providing the extension section in the embodiment of the present invention.

In the first embodiment of the invention, the extension section is arranged on the first ground wire 2 or the second ground wire 3, so that when the flexible touch panel passes through the EUV lamp tube 4, the first ground wire 2 and the second ground wire 3 almost simultaneously pass through, and a tiny and almost negligible potential difference is generated, thereby avoiding the occurrence of an ESD phenomenon and improving the yield of products.

Example two

As shown in fig. 3, a second embodiment of the present invention provides a flexible touch panel, including a body 1 and a ground line disposed around the body 1, where the body 1 is made of a flexible material, and in this embodiment, the body 1 is made of a poly-p-phthalic Plastic (PET). The ground wire is provided with a first fracture 5, and the first fracture 5 divides the ground wire into a first ground wire 2 and a second ground wire 3. The first ground line 2 and the second ground line 3 are parallel to each other in the overlapping area a at the first discontinuity 5. The first ground line 2 or the second ground line 3 is provided with an antistatic portion 6 in an overlapping area a at the first discontinuity 5.

The static electricity preventing portion 6 is a bent line provided at an end of an extension portion provided on one of the first ground line 2 and the second ground line 3 located on the inner side, as shown in fig. 3. In this embodiment, the bending line is disposed at the end of the extension section on the first ground wire 2, which can be understood as that the bending line is disposed on the extension section to form a bent ground wire, so that when passing through the EUV lamp 4, the first ground wire 2 and the second ground wire 3 almost simultaneously pass through the EUV lamp 4, thereby having an equipotential capability and avoiding the occurrence of an ESD phenomenon.

In order to ensure that the first ground line 2 and the second ground line 3 pass the EUV lamp 4 as close to simultaneously as possible without short-circuiting the two, it is preferable to arrange the above-mentioned meander line (antistatic means 6) perpendicular to the above-mentioned extension.

Further, the bent line is parallel to the vertical line of the first ground or the second ground, and thus the first ground 2 and the second ground 3 can be almost simultaneously subjected to UV light washing.

In this embodiment, the length of the extension is 1-1.5mm, as in the first embodiment. Whereas the overlapping length of the overlapping area in the prior art is 0.5-1mm, the length of the overlapping area a can reach 1.5-2.5mm, preferably 2mm, by providing the extension section in the embodiment of the present invention.

In the embodiment of the invention, the bent line is arranged at the end part of the extension section on the first ground wire 2 or the second ground wire 3, so that when the flexible touch panel passes through the EUV lamp tube 4, the first ground wire 2 and the second ground wire 3 almost simultaneously pass through, and a tiny and almost negligible potential difference is generated, thereby avoiding the occurrence of an ESD phenomenon and improving the yield of products.

EXAMPLE III

Fig. 4 is a schematic structural diagram of a flexible touch panel according to a third embodiment of the present invention, as shown in fig. 4, the differences from the first embodiment and the second embodiment are: the static electricity preventing portion 6 is a second break provided on the first ground line 2 or the second ground line 3.

If an ESD phenomenon occurs while passing through the EUV lamp 4, the second break can cause a short circuit between the small section of the ground wire formed by the first ground wire 2 after disconnection and the second ground wire 3, but the short circuit is not enough to damage the product, and most of the first ground wire 2 can still be ensured to be disconnected, thereby ensuring the overall quality of the product.

Of course, if it is evaluated that the second fracture may also accidentally cause a blast injury, the number of the second fractures may be set to two, three or more, as the case may be. In this embodiment, the number of the second interruptions is one.

Considering the size of the entire panel, the width of the second fracture may be set to be 50um-150um, and the width direction is a straight direction in which the short side of the body 1 is located in fig. 2 and 3. At this time, the overlapping area of the first ground line 2 and the second ground line 3 in the present embodiment may be known in the art. That is, a special extension is not required, and only a size sufficient to set the second fracture is satisfied.

In the embodiment of the invention, the second fracture is arranged on the first ground wire 2 or the second ground wire 3, so that the flexible touch panel is short-circuited for one time firstly when passing through the EUV lamp tube 4, but the product is not damaged enough, and most of the first ground wire 2 or the second ground wire 3 still ensures the disconnection state, thereby avoiding the occurrence of ESD (electro-static discharge) phenomenon and improving the yield of the product.

The third embodiment of the invention also provides an intelligent terminal which comprises the flexible touch panel provided by any embodiment of the invention.

The construction, features and functions of the present invention are described in detail in the embodiments illustrated in the drawings, which are only preferred embodiments of the present invention, but the present invention is not limited by the drawings, and all equivalent embodiments modified or changed according to the idea of the present invention should fall within the protection scope of the present invention without departing from the spirit of the present invention covered by the description and the drawings.
