[0028] Since the lower surface of the first glass substrate is provided with a solar charging functional layer, the first glass substrate can be charged in the presence of sunlight; and the upper surface of the second glass substrate is provided with an electrochromic functional layer, the second glass substrate can change color in the presence of sunlight, thereby adjusting the brightness of the room; the adhesive material is PVB adhesive, and the hydrogen bonds between the SiOH in the first glass substrate and the second glass substrate and the COH group in the PVB adhesive form an adhesive force, so it has better bonding ability than ordinary OCA or OCR, and there will be no glass shattering in a collision. When the screen of a car collides and breaks, the glass is not easy to splash out, thereby improving safety.

[0029] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0030] See also Figure 1, an electrochromic solar charging safety glass provided by the utility model, comprising a first glass substrate 1, a second glass substrate 2 and an adhesive 3, a solar charging functional layer 4 is arranged on the lower surface of the first glass substrate 1, a first FPC 5 is bound to the edge of the lower surface of the first glass substrate 1, and the first FPC 5 is bound and connected to the metal pin of the solar charging functional layer 4; the second glass substrate 2 is arranged below the first glass substrate 1, an electrochromic functional layer 6 is arranged on the upper surface of the second glass substrate 2, a second FPC 7 is bound to the edge of the upper surface of the second glass substrate 2, and the second FPC 7 is bound and connected to the metal pin of the electrochromic functional layer 6; the adhesive 3 is arranged between the first glass substrate 1 and the second glass substrate 2 and adheres and fixes them, and the material of the adhesive 3 is PVB adhesive. Since the lower surface of the first glass substrate 1 is provided with a solar charging functional layer 4, the first glass substrate 1 can be charged in the presence of sunlight; and the upper surface of the second glass substrate 2 is provided with an electrochromic functional layer 6, so that the second glass substrate 2 can change color in the presence of sunlight, thereby adjusting the brightness of the room; the material of the adhesive 3 is PVB adhesive, and the hydrogen bonds between the SiOH in the first glass substrate 1 and the second glass substrate 2 and the COH group in the PVB adhesive form an adhesive force, so it has better bonding ability than ordinary OCA or OCR, and there will be no glass shattering in a collision. When the screen of a car collides and breaks, the glass is not easy to splash out, thereby improving safety.

[0031] Furthermore, the first glass substrate 1 and the second glass substrate 2 are both made of colorless transparent glass, so that light can better penetrate the first glass substrate 1 and the second glass substrate 2 .

[0032] Furthermore, the first glass substrate 1 is tempered glass to improve the strength of the first glass substrate 1 .

[0033] Furthermore, an AG film, an AR film or an AF film is attached to the upper surface of the first glass substrate 1 to increase the anti-glare, anti-reflection or anti-fingerprint functions.

[0034] See also Figure 1 As a further optimization scheme of Embodiment 1, in this embodiment, a pad 51 is provided on the upper surface of the first FPC 5, and both the upper and lower surfaces of the first FPC 5 are covered with an EMI shielding film 52, and the EMI shielding film 52 is provided with an avoidance position at the pad 51. Since both the upper and lower surfaces of the first FPC 5 are provided with the EMI shielding film 52, the electromagnetic shielding capability of the first FPC 5 can be greatly improved, the stability of signal transmission is improved, various functional problems and poor display effects are avoided, and the competitiveness of the product is improved.

[0035] Furthermore, the edge of the EMI shielding film 52 located at the avoidance position is more than 0.5 mm away from the edge of the pad 51, so as to prevent the edge of the EMI shielding film 52 from contacting the pad 51 and causing a circuit break.

[0036] Furthermore, a PET film 53 is provided between the first FPC 5 and the EMI shielding film 52, and the edge of the PET film 53 near the avoidance position exceeds the edge of the EMI shielding film 52. By extending the edge of the PET film 53 near the pad 51, the edge of the PET film 53 is pulled away from the edge of the EMI shielding film 52 by a certain distance, so that even if there is a certain operation error during the attachment, the edge of the EMI shielding film 52 can be ensured not to touch the edge of the pad 51, so that the edge of the EMI shielding film 52 is insulated, and the occurrence of a short circuit problem caused by the edge of the EMI shielding film 52 touching the pad 51 is prevented, thereby improving the attachment efficiency and production yield.

[0037] Furthermore, the edge of the PET film 53 near the avoidance position exceeds the edge of the EMI shielding film 52 by more than 0.5 mm, so as to ensure that the edge of the EMI shielding film 52 does not touch the pad 51, thereby insulating the edge of the EMI shielding film 52 and preventing the occurrence of a short circuit problem caused by the edge of the EMI shielding film 52 touching the pad 51, thereby improving the attachment efficiency and production yield.

[0038] Further, the bottom of the PET film 53 is provided with a double-sided adhesive or the bottom of the PET film 53 is coated with glue. Since part of the PET film 53 is not adhesive or has insufficient adhesiveness, the bottom of the PET film 53 is provided with a double-sided adhesive or coated with glue, so that the PET film 53 can be adhered to the first FPC5.
