[0004] In the above scheme, the attachment of the protection film film body around the laser breaking gap to the touch function sheet expands the covered protection area for the touch function sheet, which results in the following shortcomings: the edge of the touch function sheet is not provided with an optimization mechanism during use, so that the anti-interference and stability of the touch function sheet are low, which reduces the accuracy and sensitivity of touch. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a high sensitivity touch function sheet edge optimization structure to solve the problem that the edge of the touch function sheet is not provided with an optimization mechanism during use, so that the anti-interference and stability of the touch function sheet are low, which reduces the accuracy and sensitivity of touch.

[0006] In order to achieve the above utility model purposes, the utility model adopts the following technical scheme: a high sensitivity touch function sheet edge optimization structure, including FPC wire, the FPC wire is arranged on the front side of the touch function sheet body, the top surface of the touch function sheet body is coated with an anti-interference coating, the top surface of the touch function sheet body is coated with a transparent conductive coating, and the anti-interference coating and the transparent conductive coating are both around the edge of the touch function sheet body.

[0007] Preferably, the thickness of the anti-interference coating is 0.02-0.1mm, and the thickness of the transparent conductive coating is 0.1-0.2μm.

[0008] Preferably, the outer wall of the touch function sheet body is fixed with an aluminum alloy frame.

[0009] Preferably, the outer side of the four corners of the aluminum alloy frame is arc-shaped.

[0010] Preferably, the inner part of the aluminum alloy frame is fixed with a rubber layer.

[0011] Preferably, the thickness of the rubber layer is 0.5-1mm.

[0012] Compared with the prior art, the high-sensitivity touch function sheet edge optimization structure has the following beneficial effects:

[0013] I. In use, by surrounding the edges of the touch function sheet body with the anti-interference coating and the transparent conductive coating, the electromagnetic shielding and electrical conductivity of the edges of the touch function sheet body can be optimized, the possibility of edge touch insensitivity or false touch can be reduced, the signal transmission efficiency and stability of the touch function sheet body can be improved, the anti-interference ability of the touch function sheet body can be enhanced, and the accuracy and sensitivity of touch can be ensured.

[0014] II. In use, by setting the thickness of the anti-interference coating to be between 0.02-0.1mm, the effective electromagnetic shielding effect can be ensured, and the cost or weight of the material will not be excessively increased. The thickness ensures that the coating can withstand the influence of external electromagnetic interference and effectively reflect or absorb interference signals. By setting the thickness of the transparent conductive coating to be between 1-0.2μm, sufficient electrical conductivity can be provided while maintaining transparency. This thickness can ensure high sensitivity of touch function and maximize light transmission, avoiding affecting the display effect. The aluminum alloy frame is beneficial to enhancing the structural strength of the edges of the touch function sheet body. It not only provides additional protection, but also serves as an electromagnetic shielding layer, reducing the influence of external electromagnetic interference on touch function, enhancing the structural stability and durability of the touch function sheet body, and improving the electromagnetic compatibility of the touch function sheet body.

[0015] Thirdly, in use, by making the four outer corners of the aluminum alloy frame rounded, not only is the overall aesthetics of the touch panel improved, but the impact force received during collisions or drops is also reduced, enhancing the impact resistance and safety of the touch panel. The rubber layer, with its excellent elasticity and cushioning properties, effectively absorbs and disperses impact force, protecting the touch panel from damage, improving its impact and shock resistance, and extending its service life. By setting the rubber layer thickness to 0.5-1mm, this range provides sufficient cushioning and protection without excessively affecting the overall size and weight of the touch panel, ensuring that the rubber layer provides adequate protection without increasing the overall burden on the touch panel, thus improving its overall performance and user experience.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, a high-sensitivity touch function chip edge optimization structure includes an FPC cable 1, which is disposed on the front side of the touch function chip body 2. The top surface of the touch function chip body 2 is coated with an anti-interference coating 3 and a transparent conductive coating 4. Both the anti-interference coating 3 and the transparent conductive coating 4 surround the edge of the touch function chip body 2.

[0023] In use, the FPC cable 1 serves as the bridge connecting the touch function chip body and the external circuitry, and its stability and reliability are crucial. By placing the FPC cable 1 on the front side of the touch function chip body, smooth and efficient signal transmission can be ensured. The anti-interference coating 3 is made of silver, which has excellent conductivity and oxidation resistance and is commonly used in high-end devices. It can effectively shield electromagnetic interference. By coating the anti-interference coating 3 around the edge of the touch function chip body 2, the stability of the touch device in complex electromagnetic environments is ensured. The transparent conductive coating 4 is made of indium tin oxide, which has good conductivity and also maintains good light transmittance. By coating the transparent conductive coating 4 around the edge of the touch function chip body 2, the touch function chip body 2 maintains high light transmittance and ensures the sensitivity and accuracy of touch response. The coating around the edge makes signal transmission more stable, avoids electrical interference in the edge area, and improves the touch experience.

[0024] By coating the anti-interference coating 3 and the transparent conductive coating 4 around the edge of the touch function sheet body 2, the electromagnetic shielding and conductivity performance of the edge of the touch function sheet body 2 can be optimized, reducing the possibility of edge touch insensitivity or accidental touch, thereby improving the signal transmission efficiency and stability of the touch function sheet body 2, enhancing the anti-interference capability of the touch function sheet body 2, and ensuring the accuracy and sensitivity of touch.

[0025] like Figure 1 and Figure 2 As shown, the thickness of the anti-interference coating 3 is 0.02-0.1 mm, and the thickness of the transparent conductive coating 4 is 0.1-0.2 μm.

[0026] In use, by setting the thickness of the anti-interference coating 3 between 0.02-0.1mm, an effective electromagnetic shielding effect can be guaranteed without excessively increasing the cost or weight of the material. The moderate thickness ensures that the coating can withstand the influence of external electromagnetic interference and effectively reflect or absorb interference signals. By setting the thickness of the transparent conductive coating 4 in the range of 1-0.2μm, it is suitable to provide sufficient conductivity while maintaining transparency. This thickness can ensure high sensitivity of the touch function, while maximizing the transmission of light and avoiding affecting the display effect.

[0027] like Figures 1-4 As shown, an aluminum alloy frame 5 is fixed to the outer wall of the touch function chip body 2, and the four outer corners of the aluminum alloy frame 5 are all arc-shaped.

[0028] In use, the aluminum alloy frame 5 enhances the structural strength of the touch panel body 2 by reinforcing its edges. This not only provides additional protection but also acts as an electromagnetic shielding layer, reducing the impact of external electromagnetic interference on the touch function. This enhances the structural stability and durability of the touch panel body 2 and improves its electromagnetic compatibility. By making the four outer corners of the aluminum alloy frame 5 rounded, the overall aesthetics of the touch panel body 2 are improved, and the impact force received during collisions or drops is reduced, thus improving its impact resistance and safety.

[0029] like Figures 1-4 As shown, a rubber layer 6 is fixed inside the aluminum alloy frame 5, and the thickness of the rubber layer 6 is 0.5-1mm.

[0030] During use, the rubber layer 6, with its excellent elasticity and cushioning properties, effectively absorbs and disperses impact forces, protecting the touch panel body 2 from damage. This improves the impact and shock resistance of the touch panel body 2 and extends its service life. By setting the thickness of the rubber layer 6 to 0.5-1mm, this thickness range provides sufficient cushioning and protection while avoiding excessive impact on the overall size and weight of the touch panel body 2. This ensures that the rubber layer 6 provides sufficient protection without increasing the overall burden on the touch panel body 2, thus improving the overall performance and user experience of the touch panel body 2.
