Description
The patent application of the invention is a divisional application based on the Chinese patent application with the application number 202011157130.8, wherein the application date is 2020, 10, 26, the invention name is an electrochromic device and an electronic terminal comprising the electrochromic device.
Technical Field
The invention belongs to the technical field of electrochromic, and particularly relates to an electrochromic device and an electronic terminal comprising the same.
Background
Electrochromic refers to a phenomenon that the optical properties of a material change in color stably and reversibly under the action of an applied electric field, and is represented by reversible changes in color and transparency in appearance. Materials having electrochromic properties are called electrochromic materials, and electrochromic materials can be classified into inorganic electrochromic materials and organic electrochromic materials. The 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 are various in types, rich in color and convenient to design, such as viologen and polythiophene.
Devices made with electrochromic materials are known as electrochromic devices. By selecting different electrochromic materials, electrochromic devices with different colors and different color changing ranges can be obtained. Electrochromic devices have very important application prospects in the fields of color-changing glasses, electronic display, military hiding, building energy conservation and the like.
Common electrochromic devices are generally composed of 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 laminated in this order. When voltage is applied, ions are conducted from the ion storage layer to the electrochromic layer through the electrolyte layer to realize color change; when a reverse voltage is applied, ions are conducted from the electrochromic layer through the electrolyte layer into the ion storage layer, effecting discoloration.
In practice, electrochromic devices may need to be treated to leave portions of the areas clear to show a specific pattern, such as a logo of the manufacturer, or as a light transmissive area for a display or signal light when used in electrochromic rear view mirrors comprising a display/signal light.
The processing method generally adopted in the prior art is to etch away the material of the corresponding area in one transparent conductive layer, and when voltage is applied, the area cannot form an electric field and cannot change color. However, this method is only suitable for non-closed patterns, and if the closed pattern is treated by this method, the area closed inside the pattern and the area outside the pattern are intermittently connected, and the area closed inside the pattern cannot be discolored as well, so that a compatible effect cannot be achieved on the break points, and therefore, the method needs to be solved.
Disclosure of Invention
Aiming at the defects existing in the prior art, the invention aims to provide an electrochromic device and an electronic terminal comprising the electrochromic device. The electrochromic device provided by the invention can present a closed pattern, and realizes the breakpoint compatible effect of the display technology.
To achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the present invention provides an electrochromic device comprising: the solid color-changing layer comprises a first substrate layer, a first transparent conductive layer, a solid color-changing layer, a second transparent conductive layer and a second substrate layer which are sequentially laminated; the electrochromic device has a colored region and a closed non-colored region dividing the colored region into at least two discrete portions; the non-discoloring region includes: a non-closed first pattern region disposed on the first transparent conductive layer, and a non-closed second pattern region disposed on the second transparent conductive layer; the first pattern area is electrically disconnected with other areas of the first transparent conductive layer except the first pattern area, and the second pattern area is electrically disconnected with other areas of the second transparent conductive layer except the second pattern area.
The first/second pattern areas are electrically disconnected in the present invention, and the areas of the first/second transparent conductive layer other than the first/second pattern areas may be electrically connected. When voltage is applied to the first transparent conductive layer and the second transparent conductive layer, the first/second pattern areas cannot form an electric field, the areas, opposite to the first pattern areas and the second pattern areas, of the electrochromic layer cannot be discolored, the areas are combined into a sealed non-discolored area, and the areas sealed inside the non-discolored area can be discolored, so that the electrochromic device can display sealed patterns, and the breakpoint compatible effect of a display technology is realized.
Preferably, the projections of the first and second patterned areas in the same direction parallel to the electrochromic device are at least partially non-overlapping.
In this embodiment of the present application, electrical conduction is achieved through a non-overlapping region, for example, the first conductive layer achieves electrical conduction in a region that does not overlap with the second pattern region, and the second conductive layer achieves electrical conduction in a region that does not overlap with the first pattern region, so that conduction in other regions is achieved to form electrical continuity.
Preferably, the electrochromic device further comprises at least one of the following features: the closed non-discoloring region means that the region other than the non-discoloring region is discontinuous; the non-closed first pattern region means that the region of the first conductive layer except the first pattern is continuous; the non-closed second pattern region means that a region of the second conductive layer other than the first pattern is continuous.
Preferably, the color-changing region comprises a discontinuous first color-changing region and a second color-changing region, and the second color-changing region is positioned on the inner side of the non-color-changing region.
Preferably, at least the outline of the first graphic region is hollowed out and/or at least the outline of the second graphic region is hollowed out.
Preferably, all the first graphic areas are hollowed out and/or all the second graphic areas are hollowed out.
Preferably, the area of the electrochromic device corresponding to the first pattern area is combined with the area of the electrochromic device corresponding to the second pattern area to form the non-color-changing area.
Preferably, the electrochromic device further comprises: the reflecting layer is arranged on the outer side of the first substrate, and the area, opposite to the non-color-changing area, of the reflecting layer is hollowed out.
In addition, the conventional electrochromic rearview mirror comprising a display/signal lamp generally adopts an electrochromic device with a non-layered structure (a liquid or gel state electrochromic material is adopted and sealed between two opposite conductive substrates), when a non-color-changing pattern is etched in the electrochromic device with the non-layered structure, because the electrochromic material is in a liquid or gel state, even if an electric field is not formed in a region of the conductive layer where the pattern is etched, surrounding electrochromic materials are gradually diffused to the etched region after being color-changed under the action of the electric field, so that the etched region starts to be color-changed, and therefore the color change of the etched region is later than that of the non-etched region, thereby forming color residues. The electrochromic device is of a layered structure, the electrochromic layer is solid, and the electrochromic layer material cannot diffuse, so that the problem of color residue cannot occur.
The term "closed non-discolored region" as used herein means that the shape of the non-discolored region is closed, that is, the region other than the non-discolored region is discontinuous. The non-closed first pattern area and the non-closed second pattern area refer to that the shapes of the first pattern area and the second pattern area are non-closed, namely the areas except the pattern area in the first transparent conductive layer and the second transparent conductive layer are continuous.
In the present invention, the "at least the outline is hollowed out" means that a section of the first/second pattern area inward from the outline does not have the first/second transparent conductive layer material, where the section may be a groove penetrating through the first/second transparent conductive layer, may be filled with the material of the adjacent layer, or may be filled with other transparent insulating materials (such as transparent polyacrylate glue). The purpose of this structure is to electrically disconnect the first/second pattern areas from other areas in the first/second transparent conductive layer. As a special case, the first/second graphic areas may also be entirely hollowed out.
In the invention, the shapes of the first pattern area and the second pattern area are only required to be ensured to be non-closed, and the normal projection shape (namely, the direction perpendicular to the electrochromic device) of the first pattern area and the second pattern area is the same as the shape of the preset closed non-color-changing area. The shapes of the first and second pattern areas may be exactly complementary or may overlap, for example. If the shapes of the first graphic region and the second graphic region are exactly complementary, the shapes of the displayed non-color-changing regions may deviate from the preset shapes due to errors, so that the shapes of the first graphic region and the second graphic region are preferably partially overlapped in the invention.
In an embodiment of the invention, the first graphic area is entirely hollowed out.
In an embodiment of the invention, the second graphic area is entirely hollowed out.
When the electrochromic device of the present invention is used in an electrochromic rearview mirror (e.g., blind lighting) that includes a display/signal lamp, a certain contrast is required because the light transmitted by the display or signal lamp as a light source needs to pass through the rearview mirror assembly from an uncolored area and then to the human eye. When the contrast is required to be constant, the higher the transmittance of the non-color-changing region is, the lower the intensity required for the corresponding light is, and the smaller the heat generated by the light emission is. Therefore, in the invention, the first pattern area and the second pattern area are preferably hollowed out completely so as to improve the transmittance of the non-color-changing area.
In one embodiment of the present invention, the solid state color change 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 layers of the first substrate layer, the ion storage layer, the ion transfer layer and the electrochromic layer, a region opposite to the hollowed-out portion of the first pattern area is hollowed out entirely or partially, or a non-through groove is provided entirely or partially.
In an embodiment of the present invention, in one or at least two layers of the second substrate layer, the ion storage layer, the ion transfer layer and the electrochromic layer, a region opposite to the hollowed-out portion of the second pattern area is hollowed out entirely or partially, or a non-through groove is provided entirely or partially.
In the present invention, under the condition of ensuring that the first pattern area and the second pattern area are electrically disconnected, the structures of the areas of the other layers, which are opposite to the hollowed-out parts of the first pattern area and the second pattern area, may be various, for example, the areas may be all hollowed-out, partially hollowed-out, all etched to form non-through grooves, or partially etched to form non-through grooves. The more the hollowed-out areas and the number of layers are, the higher the transmittance of the non-color-changing areas 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 with 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 the structure can be processed on each layer and then compounded, so that the integrity of the device structure is easier to ensure; the structure can be processed by compounding the layers, so that the problems of poor surface cleanliness, rough etched edge and the like caused by processing the structure 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, opposite to the non-color-changing area, of the reflecting layer is hollowed out.
When the electrochromic device is used for an electrochromic rearview mirror (such as blind lighting) comprising a display/signal lamp, light rays emitted by the display or the signal lamp are emitted from a hollowed-out area in the reflecting layer, so that information transmission is realized, and light incident from the environment is normally reflected by an area which is not hollowed out in the reflecting layer.
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, close to or far away from the second basal layer, of the second basal layer, and the area, opposite to the non-color-changing area, of 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, close to or far away from the first basal layer, of the first basal layer, and the area, opposite to the non-color-changing area, of the reflection layer is hollowed out.
In one embodiment of the invention, the electrochromic device further comprises a seal disposed around the sides of the electrochromic device.
In one embodiment of the present invention, the width of the non-color-changing region is greater than or equal to 0.1mm, for example, 0.1mm, 0.2mm, 0.3mm, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 3mm, 4mm, 5mm, 6mm, etc.; preferably not less than 1mm. When the electrochromic device of the invention is used for an electrochromic rearview mirror (such as blind lighting) comprising a display/signal lamp, the width of the non-color-changing zone of the invention is in the range, the outline of the graph zone is clear, and the light quantity passing through the display/signal lamp is enough to draw the attention of a driver, so that a reminding effect can be well played for 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 rear view mirror comprising a display/signal lamp.
Compared with the prior art, the invention has the following beneficial effects:
according to the invention, the first pattern area and the second pattern area which are not closed are respectively formed on the first transparent conductive layer and the second transparent conductive layer, and the first pattern area and the second pattern area are combined to form the closed non-color-changing area, so that the area which is closed inside the non-color-changing area and the area which is outside the non-color-changing area can be electrically communicated, and color change can be simultaneously carried out, so that the electrochromic device presents a closed pattern, and the breakpoint compatible effect of the display technology is realized.

Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings. It should be apparent to those skilled in the art that the detailed description is merely provided to aid in understanding the invention and should not be taken as limiting the invention in any way.
Example 1
The structure of the electrochromic device is shown in fig. 1, and the electrochromic device comprises a first substrate layer 1, a first transparent conductive layer 2, an ion storage layer 3, an ion transfer layer 4, an electrochromic layer 5, a second transparent conductive layer 6 and a second substrate layer 7 which are sequentially stacked;
as shown in fig. 2, the electrochromic device has a colored region (including a first colored region and a second colored region) and a closed, non-colored region; wherein the non-colored region divides the colored region into two discrete portions, and is therefore said to be closed;
as shown in fig. 3, the first transparent conductive layer 2 has a non-closed first pattern area, wherein the area of the first transparent conductive layer 2 except for the first pattern area is continuous, so that the first pattern area is said to be non-closed (the area shown by the first pattern area and the dotted line in fig. 3 corresponds to a non-color-change area);
as shown in fig. 4, the second transparent conductive layer 6 has a non-closed second pattern area, wherein the area of the second transparent conductive layer 6 except the second pattern area is continuous, so that the second pattern area is said to be non-closed (the area shown by the second pattern area and the dotted line in fig. 4 corresponds to the non-color-change area);
the outline of the first graph area is hollowed out, and the outline of the second graph area is hollowed out;
the shape of the normal projection of the first and second patterned areas on the same plane parallel to the electrochromic device is the same as the shape of the non-colored areas, and the first and second patterned areas are complementary.
The dashed lines shown in fig. 3 and 4 are not actually boundaries, but are merely used to help illustrate the relationship among the shapes of the first pattern region, the second pattern region, and the non-color-changing region.
In this embodiment, the hollowed-out structures at the outlines of the first pattern region and the second pattern region are formed before the layers of the electrochromic device are combined, so that the integrity of the device structure is easily ensured. The hollow structure can be formed by a preset mask when each layer is prepared; or after the complete layer is prepared, the layer is formed by a laser etching method.
In this embodiment, since the first pattern area and the second pattern area are hollowed out, and are disconnected from other areas in the first transparent conductive layer 2 and the second transparent conductive layer 6 respectively, the first pattern area and the second pattern area are electrically disconnected, the corresponding areas are not discolored, and a closed non-discolored area is formed after combination; the second color-changing area sealed inside the non-color-changing area and the first color-changing area outside the non-color-changing area can be electrically communicated, and color change can occur, so that the electrochromic device presents a sealed pattern, and the breakpoint compatibility effect of the display technology is realized.
Example 2
The present embodiment provides an electrochromic device, whose structure is shown in fig. 5, and differs from that of embodiment 1 only in that the first pattern region and the second pattern region are all hollowed out.
Compared with embodiment 1, the embodiment improves the light transmittance of the non-color-changing region while realizing the breakpoint compatible effect of the display technology by forming the structure that the first pattern region and the second pattern region are all hollowed out, and is helpful to reduce the required luminous intensity of the display or the signal lamp when the electrochromic device is used for the electrochromic rearview mirror comprising the display/signal lamp.
Example 3
The present embodiment provides an electrochromic device, whose structure is shown in fig. 6, and differs from that of embodiment 1 only in that the region of the first substrate layer 1 opposite to the hollowed-out portion of the first pattern region and the region of the second substrate layer 7 opposite to the hollowed-out portion of the second pattern region are hollowed-out.
In this embodiment, the hollowed-out structures in the first substrate layer 1, the first transparent conductive layer 2, the second transparent conductive layer 6 and the second substrate layer 7 are formed after the respective layer structures of the electrochromic device are combined, and may be etched from the outside of the first substrate layer 1 and the outside of the second substrate layer 7 respectively by laser etching, for example.
Compared with embodiment 1, the hollow structure is formed after the layers of the electrochromic device are compounded, so that the problems of poor surface cleanliness, rough etching edge and the like caused by the fact that the hollow structure is formed first and then the layers are compounded are solved while the breakpoint compatible effect of the display technology is achieved.
