Description
Technical Field
The invention belongs to the technical field of electrochromism, and particularly relates to an electrochromic device and an electronic terminal comprising the same.
Background
Electrochromism refers to a phenomenon that the optical properties of a material are subjected to stable and reversible color change under the action of an external electric field, and the electrochromism shows reversible changes of color and transparency in appearance. Materials having electrochromic properties are called electrochromic materials, and the electrochromic materials can be classified into inorganic electrochromic materials and organic electrochromic materials. The inorganic electrochromic material has the advantages of stability and quick response, such as tungsten trioxide, vanadium pentoxide, nickel oxide, titanium dioxide and the like; the organic electrochromic materials have various types and rich colors, and are convenient to design, such as viologen and polythiophene.
Devices made with electrochromic materials are referred to as electrochromic devices. By selecting different electrochromic materials, electrochromic devices with different colors and different color change ranges can be obtained. The electrochromic device has very important application prospect in the fields of color-changing glasses, electronic display, military hiding, building energy conservation and the like.
A common electrochromic device generally includes a transparent substrate layer, a transparent conductive layer, an electrochromic layer, an electrolyte layer, an ion storage layer, a transparent conductive layer, and a transparent substrate layer, which are sequentially stacked. When voltage is applied, ions are conducted from the ion storage layer to the electrochromic layer through the electrolyte layer, and color change is achieved; when a reverse voltage is applied, ions are conducted from the electrochromic layer through the electrolyte layer into the ion storage layer, and color fading is achieved.
Electrochromic devices may need to be treated in practice to leave areas that do not change color to show a particular pattern, such as to show a manufacturer's logo, or to act as a pass-through area for display or signal light when used in an electrochromic rear view mirror containing a display/signal.
The processing method usually adopted in the prior art is to etch away the material of the corresponding region in one of the transparent conductive layers, and when a voltage is applied, the region cannot form an electric field and cannot change color. However, this processing method is only suitable for non-closed patterns, and if the closed patterns are processed by this method, the area closed inside the patterns and the area outside the patterns are disconnected, the area closed inside the patterns also cannot change color, and a compatible effect cannot be achieved for the disconnection point, so it is to be solved.
Disclosure of Invention
In view of the defects of the prior art, the present invention is directed to an electrochromic device and an electronic terminal including the same. The electrochromic device provided by the invention can present closed patterns and realize the breakpoint compatible effect of the display technology.
In order to achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the present invention provides an electrochromic device comprising: the color-changing substrate comprises a first substrate layer, a first transparent conducting layer, a solid color-changing layer, a second transparent conducting layer and a second substrate layer which are sequentially stacked;
the electrochromic device has a color-changing region and a closed non-color-changing region;
the first transparent conducting layer is provided with a non-closed first pattern area, and the second transparent conducting layer is provided with a non-closed second pattern area;
at least the outline of the first graphic area is hollow, and at least the outline of the second graphic area is hollow;
the shape of the normal projection of the first graphic area and the second graphic area on the same plane parallel to the electrochromic device is the same as that of the color-invariant area.
In the invention, at least the outline of the first/second pattern area is hollow, and the first/second pattern area is not closed, so that the first/second pattern area is electrically disconnected, and the areas except the first/second pattern area in the first/second transparent conductive layer can be electrically communicated. When voltage is applied to the first transparent conducting layer and the second transparent conducting layer, the first/second graph area can not form an electric field, the area opposite to the first graph area and the second graph area in the electrochromic layer can not change color to be combined into a closed color-invariant area, and the area closed in the color-invariant area can change color, so that the electrochromic device can present a closed pattern, and the breakpoint compatible effect of the display technology is realized.
In addition, the existing electrochromic rearview mirror including a display/signal lamp generally adopts a non-laminated electrochromic device (adopting a liquid or gel state electrochromic material and sealed between two opposite conductive substrates), when a non-discolored pattern is etched in the non-laminated electrochromic device, since the electrochromic material is in a liquid or gel state, even if an electric field is not formed in a region where the pattern is etched in the conductive layer, the surrounding electrochromic material discolors first under the action of the electric field and then gradually diffuses to an etched region, so that the etched region also begins to discolor, and the discoloring of the etched region is later than that of the non-etched region, thereby forming color residue. The electrochromic device has a layered structure, the electrochromic layer is solid, and the material of the electrochromic layer cannot be diffused, so that the problem of color residue is avoided.
In the present invention, the enclosed non-color-changing region means that the shape of the non-color-changing region is enclosed, that is, the region except the non-color-changing region is discontinuous. The non-closed first graphic area and the non-closed second graphic area mean that the shapes of the first graphic area and the second graphic area are not closed, namely, the areas except the graphic areas in the first transparent conductive layer and the second transparent conductive layer are continuous.
In the present invention, the phrase "at least the contour is hollowed out" means that there is no first/second transparent conductive layer material in a section of the inward region from the contour line of the first/second graphic region, and the region may be a groove penetrating through the first/second transparent conductive layer, may also be filled with an adjacent layer material, and may also be filled with other transparent insulating materials (such as transparent polyacrylate glue). The structure is provided for electrically disconnecting the first/second pattern area from other areas in the first/second transparent conductive layer. As a special case, the first/second graphic areas may also be completely hollowed out.
In the invention, the shapes of the first graphic area and the second graphic area are ensured to be non-closed, and the normal projection shapes (namely the direction vertical to the electrochromic device) of the first graphic area and the second graphic area are the same as the preset shape of the closed non-discoloring area. For example, the shapes of the first graphic area and the second graphic area may be exactly complementary or may partially overlap. If the shapes of the first graphic area and the second graphic area are exactly complementary, the shape of the non-discolored area may deviate from the preset shape due to errors, and therefore, the shapes of the first graphic area and the second graphic area are preferably partially overlapped.
In an embodiment of the invention, the first graphic area is completely hollow.
In an embodiment of the invention, the second pattern area is completely hollow.
When the electrochromic device of the present invention is used in an electrochromic rear view mirror (e.g., a blind light) including a display/signal lamp, it is necessary to have a certain contrast ratio since light transmitted from the display or signal lamp as a light source is required to pass through the rear view mirror assembly from the non-color-changing region and then to be transmitted to human eyes. When the contrast ratio is required to be constant, the higher the transmittance of the non-color-changing region is, the lower the intensity required by the corresponding light is, and the smaller the heat generated by the light emission is. Therefore, in the present invention, it is preferable that the first pattern region and the second pattern region are all hollowed out to improve the transmittance of the non-discoloring region.
In one embodiment of the present invention, the solid coloring layer includes an ion storage layer, an ion transfer layer, and an electrochromic layer, which are sequentially stacked.
In an embodiment of the present invention, in one or at least two of the first substrate layer, the ion storage layer, the ion transfer layer, and the electrochromic layer, a region opposite to the hollow portion of the first pattern region is entirely or partially hollow, or is entirely or partially provided with a non-through groove.
In an embodiment of the present invention, in one or at least two of the second substrate layer, the ion storage layer, the ion transfer layer, and the electrochromic layer, a region opposite to the hollow portion of the second pattern region is entirely or partially hollow, or is entirely or partially provided with a non-through groove.
In the present invention, under the condition that the first pattern area and the second pattern area are electrically disconnected, the structure of the area opposite to the hollow portion of the first/second pattern area in the remaining layers may be various, for example, the area may be completely hollow, partially hollow, completely etched with a non-through groove, or partially etched with a non-through groove. The more the hollow area and the number of layers are, the higher the transmittance of the non-discoloring area is.
In the present invention, the method for forming the hollow structure or the non-through groove is not particularly limited, and for example, a mask may be preset when each layer is prepared to form the structure; or after preparing the complete layer, etching by laser to form the structure.
In the invention, the sequence between the operation of forming the hollow structure or the non-through groove and the operation of compounding each layer is not particularly limited, and for example, the structure can be processed on each layer firstly, and then each layer is compounded, so that the integrity of the device structure can be ensured more easily; and each layer can be compounded first, and then the structure is processed, so that the problems of poor surface cleanliness, rough etching edge and the like caused by the structure processed first can be reduced.
In one embodiment of the present invention, the electrochromic device further includes a first substrate disposed outside the first base layer, and a second substrate disposed outside the second base layer.
In one embodiment of the present invention, the electrochromic device further includes a reflective layer disposed outside the first or second substrate layer;
and the area of the reflecting layer, which is opposite to the invariant color area, is hollowed out.
When the electrochromic device is used for an electrochromic rearview mirror (such as blind lighting) comprising a display/signal lamp, light emitted by the display or the signal lamp is emitted from the hollowed area in the reflecting layer to realize information transmission, and the un-hollowed area in the reflecting layer normally reflects light incident in the environment.
In one embodiment of the present invention, the electrochromic device further includes a first substrate disposed outside the first base layer, and a reflective layer and a second substrate disposed outside the second base layer;
the reflecting layer is arranged on one side of the second substrate close to or far away from the second base layer, and the area, opposite to the color invariant area, in the reflecting layer is hollowed out.
In one embodiment of the present invention, the electrochromic device further includes a second substrate disposed outside the second base layer, and a reflective layer and a first substrate disposed outside the first base layer;
the reflection layer is arranged on one side of the first substrate close to or far away from the first base layer, and the area, opposite to the invariant color area, in the reflection layer is hollowed out.
In one embodiment of the present invention, the electrochromic device further comprises a sealing member disposed around a side of the electrochromic device.
In one embodiment of the present invention, the width of the non-discoloring region is not less than 0.1mm, and may be, for example, 0.1mm, 0.2mm, 0.3mm, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 3mm, 4mm, 5mm, or 6 mm; preferably ≧ 1 mm. When the electrochromic device of the present invention is used for an electrochromic rear view mirror including a display/signal lamp (e.g., blind lighting), when the width of the constant color zone of the present invention is within the above range, the outline of the graphic zone is clear, and the amount of light passing through the display/signal lamp is sufficient to attract the attention of the driver, thereby providing a good warning effect to the driver.
In a second aspect, the present invention provides an electronic terminal comprising an electrochromic device according to the first aspect.
In one embodiment of the invention, the electronic terminal is electrochromic glazing, or an electrochromic rearview mirror comprising a display/signal light.
Compared with the prior art, the invention has the following beneficial effects:
according to the invention, the non-closed first graph area and the non-closed second graph area are respectively formed on the first transparent conducting layer and the second transparent conducting layer, and the non-closed first graph area and the non-closed second graph area are combined to form the closed color-invariant area, so that the area closed in the color-invariant area and the area outside the color-invariant area can be electrically communicated, and the colors can be simultaneously changed, thus the electrochromic device presents a closed pattern, and the breakpoint compatible effect of the display technology is realized.

as shown in fig. 3, the first transparent conductive layer 2 has a non-closed first pattern region, wherein the region of the first transparent conductive layer 2 except the first pattern region is continuous, and thus the first pattern region is referred to as non-closed (the first pattern region and the region shown by the dotted line in fig. 3 correspond to an unchanged color region);
as shown in fig. 4, the second transparent conductive layer 6 has a non-closed second pattern region, wherein the region of the second transparent conductive layer 6 except for the second pattern region is continuous, and thus the second pattern region is referred to as non-closed (the second pattern region and the region shown by the dotted line in fig. 4 correspond to the non-discolored region);

the shape of the normal projection of the first graphic area and the second graphic area on the same plane parallel to the electrochromic device is the same as that of the color-invariant area, and the first graphic area and the second graphic area are complementary.
It should be noted that the dotted lines shown in fig. 3 and 4 are not actual boundaries, and are only used to help illustrate the relationship among the shapes of the first graphic region, the second graphic region, and the color-invariant region.
In this embodiment, the hollow structures at the outlines of the first pattern area and the second pattern area are formed before the layers of the electrochromic device are combined, so that the structural integrity of the device is easily ensured. The hollow structure can be formed by presetting a mask when each layer is prepared; or after preparing the complete layer, forming by laser etching.
In this embodiment, since the outlines of the first graphic area and the second graphic area are hollowed out and are respectively disconnected from other areas in the first transparent conductive layer 2 and the second transparent conductive layer 6, the first graphic area and the second graphic area are electrically disconnected, the corresponding areas do not change color, and a closed non-color-changing area is formed after combination; and can communicate between the first discoloration district of the second discoloration district that is sealed in the invariant color district inside and invariant color district outside, can take place to change colour to make electrochromic device demonstrate confined pattern, realized the breakpoint compatible effect of display technology.
