Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] See also Figure 1 , shown is a self-repairing capacitive touch screen in an embodiment of the present invention, including a touch sensor 10, a bonding portion 20, a glass cover 30, a polymer polyurethane coating 40 and an explosion-proof membrane 50.

[0030] The upper surface of the touch sensor 10 is connected to the glass cover plate 30 via the bonding portion 20, the polymer polyurethane coating 40 is coated on the upper surface of the glass cover plate 30, and the explosion-proof membrane 50 is arranged on the upper surface of the polymer polyurethane coating 40. The surface area of ​​the explosion-proof membrane 50, the polymer polyurethane coating 40 and the glass cover plate 30 are the same, and the explosion-proof membrane 50, the polymer polyurethane coating 40 and the end of the glass cover plate 30 overlap, wherein the polymer polyurethane coating 40 is used to repair damaged parts of the glass cover plate 30, and the explosion-proof membrane 50 is used to protect the glass cover plate 30.

[0031] It is understood that when an accidental collision occurs during the use of the touch screen and the surface of the glass cover plate 30 is damaged, the high-molecular-weight polyurethane repair coating coated on the surface of the glass cover plate 30 can automatically sense and initiate repairs, filling the damaged area and restoring the flatness and transparency of the glass cover plate 30. This achieves the effect of automatic touch screen repair. The self-repairing glass cover plate 30 can automatically initiate repairs when damaged, without the need for manual intervention, reducing maintenance costs. The automatic repair function can significantly extend the service life of the touch screen and reduce the frequency of replacement. The automatic repair function reduces the inconvenience and cost caused by touch screen damage and improves user satisfaction. In addition, the explosion-proof film 50 can provide preliminary protection for the glass cover plate 30 to prevent more serious damage to the glass cover plate 30.

[0032] Specifically, in this embodiment, the polymer polyurethane coating 40 is synthesized from polyurethane, flexible disulfide bonds and dynamic hexahydrogen bonds, so that the polymer polyurethane coating 40 has ultra-high strength and toughness, and can reform bonding after being damaged to achieve automatic repair.

[0033] In addition, it is worth noting that the thickness of the polymer polyurethane coating is 10 μm to 60 μm. In this embodiment, the thickness of the polymer polyurethane coating is 10 μm, which can effectively repair the damaged glass cover 30 .

[0034] Specifically, in this embodiment, the area of ​​the touch sensor 10 is smaller than that of the glass cover plate 30. The bonding portion 20 includes an OCA optical adhesive layer 21 and two optical adhesive protective layers 22. The touch sensor 10 is connected to the glass cover plate 30 via the OCA optical adhesive layer 21. The two optical adhesive protective layers 22 are symmetrically arranged at both ends of the OCA optical adhesive layer 21. The area of ​​the OCA optical adhesive layer 21 is smaller than that of the glass cover plate 30 and the touch sensor 10. The optical adhesive protective layers 22 are arranged in a stepped structure, and the ends of the optical adhesive protective layers 22 coincide with the ends of the glass cover plate 30.

[0035] It can be understood that the edge portions of the glass cover 30, the OCA optical adhesive layer 21 and the touch sensor 10 are protected by the photosynthetic adhesive protective layer 22, which not only effectively protects them but also further adheres them. The photosynthetic adhesive protective layer fills the gaps between the glass cover 30, the OCA optical adhesive layer 21 and the touch sensor 10 to improve the stability of the touch screen.

[0036] The utility model also provides an electronic device, comprising the above-mentioned self-repairing capacitive touch screen.

[0037] In summary, the self-repairing capacitive touch screen in the above-described embodiment of the present invention, when the glass cover plate 30 is damaged, the polymer polyurethane coating 40 fills the damaged area of ​​the glass cover plate 30, thereby restoring the flatness and transparency of the glass cover plate 30. Furthermore, the explosion-proof film 50 provides preliminary protection for the glass cover plate 30, preventing direct damage to the glass cover plate 30. Because the upper surface of the glass cover plate 30 is coated with the polymer polyurethane repair coating 50, which is synthesized by adding flexible disulfide bonds and dynamic hexahydrogen bonds to polyurethane, the polymer polyurethane repair coating 50 has ultra-high strength and toughness. After damage, it can reform bonds and achieve automatic repair. When the touch screen is in use and an accidental collision causes damage to the surface of the glass cover plate 30, the polymer polyurethane repair coating 50 coated on the surface of the glass cover plate 30 can automatically sense and initiate repair, filling the damaged area and restoring the flatness and transparency of the glass cover plate 30. This achieves the effect of automatic touch screen repair. This can improve the user experience, extend the service life of the touch screen, and reduce the maintenance cost of the touch screen.
