However, at this time, if the wireless charger is used to charge the LED lamp, it is necessary to reserve an installation space for the wireless charger, and the exposure of the wireless charger will also damage the overall aesthetics of the glass window design.

Contents of the invention

The present invention aims to provide an electrochromic glass with a wireless charging function and a preparation method thereof. The prepared electrochromic glass can be directly used as a wireless power supply transmitting device to charge a wireless power supply receiving device adsorbed thereon. The glass window design is more beautiful.

An electrochromic glass with a wireless charging function, which includes a first transparent substrate, on which at least two transparent conductive layers are provided, and a functional layer is provided between every two adjacent transparent conductive layers; At least one transparent conductive layer is a closed circuit structure surrounded by a strip-shaped transparent conductive film as a circuit line. One end of the transparent conductive layer is the wired power input end, and the other end is the wired power output end. The closed circuit of each layer The current directions of the transparent conductive layers of the structure are consistent with each other.

The present invention also provides a method for preparing the above-mentioned transparent conductive layer with a closed circuit structure in the electrochromic glass with wireless charging function, comprising the following steps: (1) The transparent conductive film is used as the deposited transparent conductive layer, Lay a photoresist layer on its surface; (2) Print the projected outline of the circuit line in the closed circuit on the transparent conductive film; (3) Expose the part other than the projected outline of the circuit line on the transparent conductive film; (4) ) Dissolve, wash and dry the photoresist layer in the exposed area with a developer; (5) Etch and remove the transparent conductive film in the exposed area; (6) Finally, remove the remaining photoresist layer with a photoresist etchant, A transparent conductive layer showing the shape of a circuit line, that is, a transparent conductive layer with a closed circuit structure.

The strip-shaped transparent conductive film in the transparent conductive layer of the closed circuit structure protrudes at intervals along its length direction to form several coil structures, and the current directions of all the coil structures of the same transparent conductive layer are consistent with each other. Under the same current, the larger the diameter of the coil, the greater the difference in magnetic field strength between the center and the edge. The present invention forms several coil structures by protruding at intervals along the length direction of the strip-shaped transparent conductive film, so that each coil structure A magnetic field can be generated, which can not only strengthen the magnetic field strength, but also ensure that the magnetic field strength of the entire transparent conductive layer is basically the same, no matter where the electronic decorations or promotional slogans are placed on the glass window or shop window. can be lit.

In the specific implementation process, the transparent conductive layer of each closed circuit structure contains several parallel circuits, and all the parallel circuits are arranged in parallel. The angle is 45° or 60° or 90°. Since the coils of most existing electronic decoration products are circuit lines containing two coil structures, when the coil structures on the electronic decoration products respectively overlap with the coil structures of the transparent conductive layer, the electromagnetic induction effect is the best. The present invention forms a special angle such as 45° or 60° or 90° between the center line of the adjacent two coil structures on the adjacent parallel line and the parallel line of the parallel line, so that the electronic decoration product is adsorbed on the glass window or When it is on the window, it is easier to realize the alignment of the coil structures of the two.

On the uppermost transparent conductive layer of the present invention, the second transparent base material is set again, like this, the two sides of the electrochromic glass that forms are all provided with transparent base material, can play material layers such as transparent conductive layer and functional layer better. Protective effects.

The first transparent substrate and the second transparent substrate in the present invention may be glass (ordinary glass, chemically strengthened glass, etc.), or other transparent materials such as plastic.

The basic structure of the existing electrochromic glass is as follows: a first transparent conductive layer, an electrochromic layer, an electrolyte layer, an ion storage layer and a second transparent conductive layer are sequentially deposited on the first transparent substrate, and then the second transparent conductive layer is deposited on the second transparent substrate. The second transparent substrate is set on the conductive layer. That is, the functional layer of the present invention is an electrochromic layer, an electrolyte layer, an ion storage layer, or the like. However, the structure of the electrochromic glass is not limited thereto. It may also contain a third transparent conductive layer between the first transparent conductive layer and the second transparent conductive layer (for example, the first transparent conductive layer is sequentially deposited on the first transparent substrate. Transparent conductive layer, electrochromic layer, electrolyte layer, ion storage layer, the third transparent conductive layer, transparent insulating layer and the second transparent conductive layer, and then set the common electro-induced of the second transparent substrate on the second transparent conductive layer color-changing glass structure), and even more transparent conductive layers. For the present invention, as long as at least one transparent conductive layer is a transparent conductive layer of a closed circuit structure, its wireless charging function can be realized.

The etching described in step (5) in the method for preparing the transparent conductive layer with a closed circuit structure in the above-mentioned electrochromic glass with wireless charging function of the present invention can adopt a dry etching method or a wet etching method, These two etching methods are common etching methods in the art.
