Referring to fig. 1 to 3 together, fig. 1 is a schematic structural layer diagram of an improved front electrochromic module, fig. 2 is a schematic structural layer diagram of a bonding region of the improved front electrochromic module, and fig. 3 is a schematic structural sectional view at a-a in fig. 2. Wherein, in the technical scheme before improving, its electrochromic module includes range upon range of setting in proper order: the solar cell comprises an upper substrate 1, an upper ITO 2, a discoloring layer 3, an electrolyte layer 4, an ion storage layer 5, a lower ITO 6, a lower substrate 7, an upper metal wire 8 and a lower metal wire 9; in addition, for the convenience of wire leading (binding), the upper metal trace 8 and the lower metal trace 9 are generally connected through a silver paste 95 (not shown), that is, the lower metal trace 9 is guided to one side of the upper metal trace 8, so as to achieve the purpose of single-side wire leading.

The metal trace 180 includes but is not limited to a multi-layer trace structure such as a silver paste line, a copper plated layer, an aluminum plated layer, or a molybdenum aluminum molybdenum layer. In order to make the electrochromic module have a faster color change speed, the sheet resistance of the first conductive layer 120 and the second conductive layer 140 is set to be 10-150 ohms, such as 10 ohms, 20 ohms, 40 ohms, 50 ohms, 80 ohms, 100 ohms, 120 ohms, 150 ohms, and so on; the sheet resistance of the first metal trace 181 and the second metal trace 182 may be 0.05-2 ohms, and may specifically be 0.05 ohms, 0.06 ohms, 0.1 ohms, 1.2 ohms, 1.5 ohms, 2 ohms, and the like, which is not limited herein. The coloring speed of the electrochromic module can be between 3-20s, the fading speed between 3-15s, or faster. It should be noted that the terms "first", "second" and "third" in the embodiments of the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

Optionally, referring to fig. 5, in this embodiment, both the first metal trace 181 and the second metal trace 182 may be embedded in the rubber frame 160 (of course, in some other embodiments, the first metal trace 181 and the second metal trace 182 may also be disposed in the electrochromic layer 131), so as to realize physical isolation from the electrochromic layer 131 and the electrolyte layer 133, and prevent the electrochromic layer 131 and the electrolyte layer 133 from chemically corroding the first metal trace 181 and the second metal trace 182.

Optionally, referring to fig. 4 and fig. 6 together, fig. 6 is a schematic partial sectional view at C-C in fig. 4; the electrochromic module 100 in this embodiment further includes a flexible circuit board 183, where the flexible circuit board 183 is connected to the first trace leading-out end 1811 of the first metal trace 181 and the second trace leading-out end 1821 of the second metal trace 182, and the flexible circuit board 183 is configured to connect the electrochromic module to a control circuit board (specifically, a control circuit board of an electronic device or a self-contained chip structure, which is not specifically limited herein). It should be noted that in some other embodiments, the electrochromic module 100 may also be a structure that does not include metal traces, and the first conductive layer 120 and the second conductive layer 140 are directly connected to the control circuit board through the flexible circuit board.

The electrochromic module in the embodiment of the application mainly aims at simplifying the structure of the electrochromic module, the electrochromic module only comprises one layer of ITO electrode, and the ITO electrode can be divided into X, Y two areas by etching or laser etching. And respectively manufacturing metal wires on X, Y ITO, overlapping the metal wires with the ITO, and leading out the wires to be connected with an external circuit. Compared with the technical scheme before improvement, the electrochromic module in the embodiment of the application has no ion storage layer, and one ITO electrode is reduced, namely PET/ITO on one side is replaced by a common PET film.

The electrochromic layer has a plurality of oxidation-reduction states, and the technical scheme is illustrated by taking reduction-state coloring and oxidation-state fading as examples. When the positive pole of the external power supply is connected with the Y area and the negative pole of the power supply is connected with the X area: the electrochromic layer in the Y area is subjected to oxidation reaction, and the color fading is changed into transparency; the electrochromic layer in region X undergoes a reduction reaction, maintaining the coloration. Meanwhile, the conduction and the migration of the anions and cations in the electrolyte layer are respectively carried out to X, Y two poles to balance the charges, and the system reaches a stable state. When the positive and negative poles of the external power supply are switched, the electrochromic layer in the X, Y area is subjected to reverse redox reaction, namely, the coloring and fading conversion. When the area difference of the X/Y areas is large, if X/Y is greater than 2, the color of the X area is not obviously changed, and the color of the Y area is normally changed, so that the contrast is larger.

In the embodiment, the first conductive layer 120 (including the electrochromic layer 131 disposed thereon) and the second conductive layer 140 (including the electrochromic layer 131 disposed thereon) are disposed on the first substrate 110 in a two-part position relationship in the figure, and may have an effect of changing color in an X region alone, changing color in a Y region alone, or changing color alternately on both sides of the X region and the Y region.

Such as an X region surrounding a Y region and a Y region surrounding the X region or partially surrounding the X region, and the like, which are not limited herein.

Optionally, referring to fig. 7, fig. 7 is a schematic structural diagram of another embodiment of the electrochromic module of the present application, in which a water and oxygen barrier layer 170 is disposed on at least one of an outer surface of the second substrate 150 facing away from the electrolyte layer 133 and an outer surface of the first substrate 110 facing away from the first conductive layer 120. In the illustration of the present embodiment, a water and oxygen barrier layer 170 is disposed on an outer surface of the second substrate 150 away from the electrolyte layer 133 for illustration, and certainly, in some other embodiments, a water and oxygen barrier layer 170 may be disposed on an outer surface of the first substrate 110 away from the first conductive layer 120, and a water and oxygen barrier layer 170 may be disposed on both an outer surface of the second substrate 150 away from the electrolyte layer 133 and an outer surface of the first substrate 110 away from the first conductive layer 120.

The material of the water-oxygen barrier layer 170 is selected from any one of a dense metal oxide layer, an inorganic non-metal layer, or a composite layer formed by stacking materials and inorganic materials. Such as alumina, silicon oxide, titanium oxide, a synthetic resin material, or a laminated composite structure of a plurality of materials, or the like. The water-oxygen barrier layer 170 may be formed on the surface of the second substrate 150 by spraying, screen printing, physical vapor deposition, or the like. The water oxygen barrier layer 170 is used to isolate external water vapor and air, and since the electrochromic material in the electrochromic module is sensitive to water oxygen and is easily ineffective, it needs to be protected by the water oxygen barrier layer. The water-oxygen barrier layer 170 in this embodiment has a water vapor transmission rate WVTR of less than 0.02 g/m/day. The water vapor permeation direction of the water oxygen barrier layer 170 in the embodiment of the present application is a physical characteristic that the water oxygen barrier layer 170 permeates from one side surface of the water oxygen barrier layer 170 in the thickness direction to the opposite side surface. The test conditions were ambient temperature 20 ℃ and relative humidity 100%. In addition, in some other embodiments, the water oxygen barrier layer 170 may also be a structure with a substrate and a sprayed water oxygen barrier material disposed on the substrate, and is not limited herein.

Optionally, in some embodiments, at least one of the first substrate 110 and the second substrate 150 is a water oxygen barrier film, that is, the first substrate 110 and the second substrate 150 are structures of water oxygen barrier films themselves.

Optionally, referring to fig. 8, fig. 8 is a schematic structural diagram of another embodiment of the electrochromic module of the present application, in which an appearance film layer 190 is disposed on at least one of an outer surface of the second substrate 150 facing away from the electrolyte layer 133 and an outer surface of the first substrate 110 facing away from the first conductive layer 120. In the embodiment, the illustration and the appearance film layer 190 are disposed on the outer surface of the first substrate 110 away from the first conductive layer 120 for illustration.

The appearance film layer 190 may include a carrier plate, and at least one of an ink layer, an optical coating layer, and a texture layer stacked on the carrier plate. In some other embodiments, the appearance film layer 190 may also be a plating layer structure that does not include a carrier plate, but is only plated on the outer surface of the first substrate 110, which is not limited herein. The electrochromic module 100 can display the display effect of the appearance film layer 190 and the color-changing material layer 131 in an overlapping manner. In addition, the appearance film layer 190 itself can also be of a gradual change effect, and when the appearance film layer 190 itself is of a gradual change effect, the appearance film layer can present a richer appearance effect after being superposed with the color-changing material layer 131. It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present application are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In addition, in other embodiments, a water and oxygen barrier layer and an appearance film layer may be further disposed on one side of the second substrate 150. In the electrochromic module structure in this embodiment, a conductive layer is omitted, so that the design of the substrate without the conductive layer is more flexible, for example, the second substrate 150 can be directly replaced by a water-oxygen barrier film or an appearance film. In addition, the frame 160 can also be packaged by dispensing from the periphery of the second substrate 150, the conductive layer, and the color-changing material layer, please refer to fig. 9, and fig. 9 is a schematic structural diagram of another embodiment of the electrochromic module according to the present application.

Optionally, referring to fig. 10 and fig. 11 together, fig. 10 is a schematic overall structure diagram of another embodiment of the electrochromic module of the present application, and fig. 11 is a schematic cross-sectional structure diagram at a position D-D of the electrochromic module in the embodiment of fig. 10; optionally, the appearance film layer 190 in this embodiment may be provided with a pattern 191, wherein the pattern 191 may be a hollow pattern. The pattern may be a logo or a special pattern customized by a user, and is not limited herein. Most of the area of the appearance film layer 190 may be opaque or translucent (e.g., a color layer, a texture layer, etc.), and the logo area may be transparent. In the illustration of the present embodiment, the pattern 191 of the appearance film 190 is located in the Y region for example. When the X area is connected with the positive electrode of the power supply and the Y area is connected with the negative electrode of the power supply, the Y area is colored, and the logo is in a colored state in appearance; when the positive electrode and the negative electrode of the power supply are switched, the Y area fades, and the appearance shows that the logo is in a fading state. The technical scheme of the embodiment of the application has the characteristics that the local few-part regional color change is realized, and the EC device with the traditional structure is in the integral color change. Therefore, the scheme is suitable for a local color changing scene, and the mobile phone back shell with local logo color changing is taken as an example for illustration. For other laminated structures of the electrochromic module, reference may be made to the description of the foregoing embodiments, and further description is omitted here.

Besides the mobile phone backshell application with the local logo color change, further, multiple applications such as information notification display and the like can be realized. Referring to fig. 12, fig. 12 is a schematic structural diagram of another embodiment of an electrochromic module according to the present application, in which an ITO electrode (specifically, the second conductive layer 140 corresponding to the Y region) of the electrochromic module according to the present application may be etched into a plurality of independent blocks, respectively a logo region and an information symbol region (the information symbol region includes T1, T2, and T3 regions for example), each of which is relatively independent (independent driving control). The appearance film layer 190 may be hollowed out in the corresponding region, and the other regions may be opaque or translucent. When the electrodes of the logo area or the information symbol area (T1, T2 and T3) are connected with the positive electrode of the power supply, and the other areas are connected with the negative electrode of the power supply, the effect of partial area color change can be obtained.

Compared with an electrochromic device with a traditional structure, the electrochromic module with the single-layer electrode provided by the embodiment of the application has the advantages of simple structure and low cost: one layer of ITO electrode and ion storage layer material is reduced, the cost of the part is saved, and the whole module of the electrochromic module is thinner; the process is simplified: the positive and negative wiring is led out from the electrode substrate on the same surface, and the FPC is bonded on one surface, so that the problem of conduction of upper and lower electrodes of the traditional device is avoided; localized (patterned) color shifting can be achieved by etching the single layer thin film electrode into regions.
