Description

Technical Field

[0001] The utility model relates to an electrochromic device used as an electronic identification plate. Background Art

[0002] At present, electrochromic devices, usually referring to electrochromic glass, can reversibly change between a transparent state and a colored state under the action of an external electric field. Its working principle is that the electrochromic material in the electrochromic device undergoes an oxidation-reduction reaction under the action of an electric field, thereby changing the absorption and transmittance of light, which then manifests as a darkening or lightening of the color. For example, an electrochromic device is disclosed in a Chinese patent with publication number CN214751247U. However, existing electrochromic devices can only achieve full-surface color change, that is, they only have the function of full-surface coloring or full-surface fading, and cannot achieve separate control of color change in local areas. Therefore, the use scenarios of existing electrochromic devices are greatly restricted, such as being unable to be used as electronic signboards, and the scope of application is limited. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an electrochromic device used as an electronic signboard, which can realize the color change of a local area independently, can be used as an electronic signboard, can realize the function of electronic digital display, and can expand the use scenarios and application scope.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: an electrochromic device used as an electronic sign, which includes a first substrate and a second substrate located in front of the first substrate;

[0005] At least two first conductive film portions are provided on the front end surface of the first substrate;

[0006] At least two second conductive film portions corresponding to the first conductive film portions are provided on the rear end surface of the second substrate, and the second conductive film portions are aligned with the corresponding first conductive film portions;

[0008] Furthermore, the first conductive film portion and / or the second conductive film portion is an ITO film.

[0010] A second wire portion corresponding to the second conductive film portion is also provided on the rear end surface of the second substrate, one end of the second wire portion is connected to the corresponding second conductive film portion, and the other end of the second wire portion extends to the edge of the second substrate.

[0011] Furthermore, the first wire portion and / or the second wire portion is an ITO film.

[0012] Furthermore, the electrochromic device used as an electronic sign also includes a power supply, and the first wire portion and the second wire portion are both connected to the power supply.

[0013] Further, the first conductive film portion and the second conductive film portion correspond to the electrochromic material portion one by one respectively;

[0014] The first wire portion corresponds to the first conductive film portion one by one;

[0020] Furthermore, the insulating material layer is a transparent insulating glue.

[0021] Furthermore, the first substrate and / or the second substrate is / are made of transparent glass.

[0022] After adopting the above technical solution, when the corresponding first conductive film part and the corresponding second conductive film part are powered on, an electric field can be applied to the corresponding electrochromic material part, thereby making the color of the corresponding electrochromic material part darker. When the corresponding first conductive film part and the corresponding second conductive film part are powered off, the electric field will disappear, thereby making the color of the corresponding electrochromic material part lighter or even transparent. Therefore, by powering on or off each first conductive film part separately, and by powering on or off each second conductive film part separately, a part of the electrochromic material part becomes darker due to power on, and the remaining part of the electrochromic material part becomes transparent due to power off, thereby realizing the individual control of color change of each electrochromic material part, that is, realizing the individual control of color change of a local area; and the electrochromic material part with darker color can be combined to form various patterns, characters or numbers, thereby realizing the function of electronic digital display, and can display various numbers, characters and patterns, so that the electrochromic device can be used as an electronic signboard, expanding the use scene and application range.

[0030] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0031] like Figures 1 to 7As shown, an electrochromic device used as an electronic signboard comprises a first substrate 1 and a second substrate 2 located in front of the first substrate 1;

[0032] At least two first conductive film portions 3 are provided on the front end surface of the first substrate 1;

[0033] At least two second conductive film portions 4 corresponding to the first conductive film portions 3 are provided on the rear end surface of the second substrate 2, and the second conductive film portions 4 are aligned with the corresponding first conductive film portions 3;

[0034] An insulating material layer 5 is stacked between the first substrate 1 and the second substrate 2, and at least two electrochromic material portions 6 corresponding to the first conductive film portion 3 and the second conductive film portion 4 are embedded in the insulating material layer 5. The electrochromic material portions 6 are stacked between the corresponding first conductive film portion 3 and the corresponding second conductive film portion 4, and the electrochromic material portions 6 are electrically connected to the corresponding first conductive film portion 3 and the corresponding second conductive film portion 4. Specifically, as Figure 7 As shown, when the corresponding first conductive film portion 3 and the corresponding second conductive film portion 4 are powered on, an electric field can be applied to the corresponding electrochromic material portion 6, thereby making the color of the corresponding electrochromic material portion 6 darker. When the corresponding first conductive film portion 3 and the corresponding second conductive film portion 4 are powered off, the electric field disappears, thereby making the color of the corresponding electrochromic material portion 6 lighter or even transparent. Therefore, by powering on or off each first conductive film portion 3 separately, and by powering on or off each second conductive film portion 4 separately, a part of the electrochromic material portion 6 becomes darker due to power on, and the remaining part of the electrochromic material portion 6 becomes transparent due to power off, thereby realizing the individual control of color change of each electrochromic material portion 6, that is, realizing the individual control of color change of a local area; and the darkened electrochromic material portion 6 can be combined to form various patterns, characters or numbers, thereby realizing the function of electronic digital display, and can display various numbers, characters and patterns, so that the electrochromic device can be used as an electronic signboard, expanding the use scene and application range.

[0035] Specifically, the first conductive film portion 3 and the second conductive film portion 4 are both ITO films.

[0036] like Figures 1 to 7 As shown, a first wire portion 7 corresponding to the first conductive film portion 3 is further provided on the front end surface of the first substrate 1, one end of the first wire portion 7 is connected to the corresponding first conductive film portion 3, and the other end of the first wire portion 7 extends to the edge of the first substrate 1;

[0037] A second wire portion 8 corresponding to the second conductive film portion 4 is also provided on the rear end surface of the second substrate 2, one end of the second wire portion 8 is connected to the corresponding second conductive film portion 4, and the other end of the second wire portion 8 extends to the edge of the second substrate 2; specifically, the corresponding first conductive film portion 3 can be energized through the corresponding first wire portion 7, and similarly, the corresponding second conductive film portion 4 can be energized through the corresponding second wire portion 8.

[0038] In this embodiment, both the first wire portion 7 and the second wire portion 8 are ITO films.

[0039] like Figure 6 As shown, the electrochromic device used as an electronic signboard may also include a power supply 9, and the first wire portion 7 and the second wire portion are both connected to the power supply 9; specifically, the power supply 9 has a power management chip, and under the control of the power management chip, each first conductive film portion 3 and each second conductive film portion 4 can be powered on or off separately.

[0040] In this embodiment, the first conductive film portion 3 and the second conductive film portion 4 correspond to the electrochromic material portion 6 respectively, the first wire portion 7 corresponds to the first conductive film portion 3 one by one, and the second wire portion 8 corresponds to the second conductive film portion 4 one by one.

[0041] like Figures 1 to 7 As shown, the first conductive film portions 3 are arranged separately from each other on the front end surface of the first substrate 1;

[0042] The second conductive film portions 4 are arranged on the rear end surface of the second substrate 2 and are spaced apart from each other;

[0043] The electrochromic material portions 6 are arranged in a spaced relationship from each other in the insulating material layer 5 .

[0044] like Figures 1 to 7 As shown, the electrochromic material portions 6 are provided in plurality and are distributed in an "8" shape; in this embodiment, the electrochromic material portions 6 are provided in seven and are distributed in an "8" shape, and the numbers 0 to 9 can be displayed by darkening the color of the electrochromic material portions 6 in different combinations.

[0045] In this embodiment, the insulating material layer 5 may be a transparent insulating glue, and the first substrate 1 and the second substrate 2 may be transparent glass.

[0046] Specifically, a first conductive glass is taken, wherein the first conductive glass has a first substrate 1 and a first ITO layer, and the first ITO layer is laser marked, and the remaining portion of the first ITO layer after laser marking forms a first conductive film portion 3 and a first wire portion 7. A second conductive glass is taken, wherein the second conductive glass has a second substrate 2 and a second ITO layer, and the second ITO layer is laser marked, and the remaining portion of the second ITO layer after laser marking forms a second conductive film portion 4 and a second wire portion 8. Then, an electrochromic material is applied to a portion corresponding to the first conductive film portion 3 on the front end surface of the first substrate 1, and an insulating material is applied to the remaining portion of the front end surface of the first substrate 1, and then the first substrate 1 and the second substrate 2 are bonded and cured, and then cured to form an insulating material layer 5 and an electrochromic material portion 6.

[0047] In summary, when the corresponding first conductive film portion 3 and the corresponding second conductive film portion 4 are powered on, an electric field can be applied to the corresponding electrochromic material portion 6, thereby making the color of the corresponding electrochromic material portion 6 darker. When the corresponding first conductive film portion 3 and the corresponding second conductive film portion 4 are powered off, the electric field disappears, thereby making the color of the corresponding electrochromic material portion 6 lighter or even transparent. Therefore, by powering on or off each first conductive film portion 3 separately, and by powering on or off each second conductive film portion 4 separately, a part of the electrochromic material portion 6 becomes darker due to power on, and the remaining part of the electrochromic material portion 6 becomes transparent due to power off, thereby realizing the individual control of color change of each electrochromic material portion 6, that is, realizing the individual control of color change of a local area; and the darkened electrochromic material portion 6 can be combined to form various patterns, characters or numbers, thereby realizing the function of electronic digital display, and can display various numbers, characters and patterns, so that the electrochromic device can be used as an electronic signboard, expanding the use scene and application range.
