The examples described below with reference to the drawings are exemplary and are only used to explain the present application, and should not be construed as limiting the present application.
本申请旨在至少在一定程度上解决相关技术中的技术问题之一。This application is intended to solve at least one of the technical problems in the related technology.
本申请是基于发明人的以下发现而完成的：This application is based on the following findings by the inventors:
目前电致变色器件的走线方式较为单一，例如，直接在导电基材上接铜片，通过铜片将导电基材与外界的控制电路接通，实现控制电路对电致变色器件的电压控制，进而实现变色。发明人发现，上述走线方式需要的空间较大、可靠性较差，无法使用在手机等电子设备中，并且上述走线方式较单一，只能实现单一区域的变色，外观单调，难以满足用户对多彩外观的需求。At present, the wiring method of the electrochromic device is relatively simple. For example, a copper sheet is directly connected to the conductive substrate, and the conductive substrate is connected to the external control circuit through the copper sheet, thereby realizing the voltage control of the electrochromic device by the control circuit. , And then achieve discoloration. The inventor found that the above wiring method requires large space and poor reliability, and cannot be used in electronic devices such as mobile phones. Moreover, the above wiring method is relatively single, which can only achieve color change in a single area, and the appearance is monotonous, which is difficult to satisfy users. The need for a colorful look.
有鉴于此，在本申请的一个方面，本申请提出了一种电致变色器件。在本申请的一些示例中，参考图1，该电致变色器件包括：第一电极层100、电致变色层200、第二电极层300、导线400。其中，电致变色层200设置在第一电极层100和第二电极层300之间，导线400连接第一电极层100和第二电极层300(图1中未示出导线连接第二电极层的情况)，导线400分别位于该电致变色器件相对的两侧(如图4所示)，用于向第一电极层100和第二电极层300施加电压，以形成可使电致变色层200发生变色的电场。由此，该电致变色器件的走线方式具有走线简单、占用空间较小、可靠性较高等优点，满足电子设备的应用要求。In view of this, in one aspect of the present application, the present application proposes an electrochromic device. In some examples of the present application, referring to FIG. 1, the electrochromic device includes: a first electrode layer 100, an electrochromic layer 200, a second electrode layer 300, and a wire 400. The electrochromic layer 200 is disposed between the first electrode layer 100 and the second electrode layer 300, and a wire 400 connects the first electrode layer 100 and the second electrode layer 300 (the wire is not shown in FIG. 1 connecting the second electrode layer Case), the wires 400 are respectively located on opposite sides of the electrochromic device (as shown in FIG. 4), and are used to apply a voltage to the first electrode layer 100 and the second electrode layer 300 to form an electrochromic layer. 200 discolored electric field. Therefore, the wiring method of the electrochromic device has the advantages of simple wiring, small occupied space, high reliability, etc., and meets the application requirements of electronic equipment.
本领域技术人员能够理解的是，电致变色器件是通过在两个电极之间形成电场，电致变色材料在电场作用下发生反应(如离子的掺杂和脱掺杂)而实现变色的。因此，导 线400通过诸如柔性电路板等结构连接外电路，以在第一电极层和第二电极层之间形成电场。换句话说，需要在第一电极层和第二电极层上施加不同的电压以形成用于变色的电场。因此，第一电极层和第二电极层之间不能够通过同一根导线直接相连。具体地，电致变色器件可以包括多个导线，其中的一根与第一电极层相连，另一根与第二电极层相连。Those skilled in the art can understand that an electrochromic device realizes discoloration by forming an electric field between two electrodes, and the electrochromic material reacts under the action of the electric field (such as doping and dedoping of ions). Therefore, the wire 400 is connected to an external circuit through a structure such as a flexible circuit board to form an electric field between the first electrode layer and the second electrode layer. In other words, different voltages need to be applied to the first electrode layer and the second electrode layer to form an electric field for discoloration. Therefore, the first electrode layer and the second electrode layer cannot be directly connected through the same wire. Specifically, the electrochromic device may include a plurality of wires, one of which is connected to the first electrode layer and the other is connected to the second electrode layer.
为了便于理解，下面首先对根据本申请示例的电致变色器件进行简单说明：In order to facilitate understanding, the following first briefly describes the electrochromic device according to the example of the present application:
如前所述，目前的电致变色器件的走线方式，多是直接在导电基材上接铜片，利用铜片进行走线，实现导电基材与外界控制电路的连接。具体的，参考图2，此种连接方式需要首先在第一电极层100的边缘处涂抹一层导电银浆20，随后将铜片10粘附在导电银浆20上，实现铜片10与第一电极层100的电连接。上述走线方式中，铜片10占用的空间较大，导致电致变色器件走线区域的面积较大。由于电致变色器件是需要通过电致变色层发生变色，而实现其器件功能的，因此，电致变色器件靠外侧的基板以及电极层均为透明结构，以便下方的电致变色层的颜色可以透过上方的电极层和基板，被用户观测到。然而前述的用于实现电连接的铜片为不透明结构，因此，造成与铜片相连区域在外观上可见，一方面不透明的铜片影响电致变色器件的外观，另一方面若通过印刷油墨来遮挡铜片，印刷油墨区域的面积会较大，导致电致变色器件具有较宽的边框，影响其外观。As mentioned earlier, the current wiring method of electrochromic devices is mostly to directly connect a copper sheet to a conductive substrate, and use the copper sheet for wiring to realize the connection between the conductive substrate and the external control circuit. Specifically, referring to FIG. 2, this connection method needs to first apply a layer of conductive silver paste 20 on the edge of the first electrode layer 100, and then adhere the copper sheet 10 to the conductive silver paste 20 to realize the copper sheet 10 and the first An electrode layer 100 is electrically connected. In the above wiring method, the space occupied by the copper sheet 10 is relatively large, resulting in a larger area of the wiring area of the electrochromic device. Since the electrochromic device needs to change its color through the electrochromic layer to realize its device function, the substrate and the electrode layer on the outer side of the electrochromic device are transparent structures, so that the color of the underlying electrochromic layer can be changed. Through the electrode layer and substrate above, it is observed by the user. However, the aforementioned copper sheet for electrical connection is an opaque structure, so that the area connected to the copper sheet is visible in appearance. On the one hand, the opaque copper sheet affects the appearance of the electrochromic device, and on the other hand, it is obtained through printing ink. When the copper sheet is blocked, the area of the printing ink area will be larger, which causes the electrochromic device to have a wider frame, which affects its appearance.
目前的电子设备，不论是外观壳体，还是显示屏幕，均追求窄边框化、外观一体化。显然，上述具有铜片连接区域的存在，令该电致变色器件应用于电子设备壳体中时，需要至少在壳体的边框处对铜片等结构进行遮挡。由此，造成该壳体不能够具有均一的电致变色外观，从而影响电子设备壳体的外观，不适用于电子设备中。Current electronic devices, regardless of appearance casing or display screen, are pursuing narrow bezels and integrated appearance. Obviously, the existence of the above-mentioned copper sheet connection area makes the electrochromic device used in an electronic device housing to shield structures such as copper sheets at least at the frame of the housing. As a result, the casing cannot have a uniform electrochromic appearance, which affects the appearance of the electronic device casing, and is not suitable for use in electronic devices.
在本申请的一些示例中，该电致变色器件还包括：柔性电路板500(如图1所示)，导线400与柔性电路板500相连，由此，可以通过导线以及柔性电路板实现两个电极层与外界控制电路的连接。In some examples of the present application, the electrochromic device further includes: a flexible circuit board 500 (as shown in FIG. 1), and the conductive wire 400 is connected to the flexible circuit board 500. Thus, two wires can be implemented through the conductive wire and the flexible circuit board. The connection between the electrode layer and the external control circuit.
在本申请的一些示例中，在两个电极层的边缘处分别设置导线，并将导线与柔性电路板电连接，通过导线以及柔性电路板实现两个电极层与外界控制电路的连接，相较于现有技术通过铜片从电极层上走线出来，本申请通过导线从电极层上走线出来，一方面走线占用的空间较小，且走线方式简单，可靠性较高，导线与柔性电路板配合，可以进一步减小走线区的面积，使得应用该电致变色器件的壳体具有良好的外观效果。也即是说，与利用铜片等金属实现连接的方式相比，一方面导线占用的面积更小，另一方面，柔性电路板可弯折，可进一步减小占用的空间，且柔性电路板弯折到电致变色器件的背面，有利于壳体的窄边框化。In some examples of the present application, wires are respectively provided at the edges of the two electrode layers, and the wires are electrically connected to the flexible circuit board. The two electrode layers are connected to the external control circuit through the wires and the flexible circuit board. In the prior art, the copper layer is routed from the electrode layer, and the application is routed from the electrode layer through a wire. On the one hand, the space occupied by the wire is small, and the wiring method is simple, the reliability is high, and the wire and The cooperation of the flexible circuit board can further reduce the area of the routing area, so that the casing to which the electrochromic device is applied has a good appearance effect. In other words, compared with the method of using copper and other metals to achieve the connection, on the one hand the area occupied by the wire is smaller, on the other hand, the flexible circuit board can be bent, which can further reduce the occupied space, and the flexible circuit board Bending to the back of the electrochromic device is beneficial for narrowing the frame of the case.
下面根据本申请的具体示例，对该电致变色器件的各个结构进行详细说明：Hereinafter, each structure of the electrochromic device will be described in detail according to a specific example of the present application:
在本申请的一些示例中，导线400的具体构成材料不受特别限制，例如，为了进一步提升电致变色器件的透明度，导线400可以由透明导电材料形成，由此，导线在外观上不可见，从而不影响电致变色器件走线区域的外观。例如，在本申请的一些示例中，导线400可以为具有一定粘性的导电银浆，可通过控制导电银浆中含有的银粒子的浓度以及银粒子的粒径，控制导电银浆的透过率，形成透明或是半透明的导线400。在本申请的另一些示例中，导线400可以是由银纳米线形成的。具体的，可以是将银纳米线分散在有机溶剂中，通过包括但不限于喷涂、印刷等工艺形成的。在本申请的另一些示例中，导线400可以是由氧化铟锡(ITO)形成的。由此，利用上述材料形成导线，可以使该导线具有良好的导电性，且不影响电致变色器件走线区域的外观。In some examples of the present application, the specific constituent material of the lead 400 is not particularly limited. For example, in order to further improve the transparency of the electrochromic device, the lead 400 may be formed of a transparent conductive material, so that the lead is not visible in appearance. This does not affect the appearance of the routing area of the electrochromic device. For example, in some examples of the present application, the wire 400 may be a conductive silver paste having a certain viscosity, and the transmittance of the conductive silver paste may be controlled by controlling the concentration of the silver particles contained in the conductive silver paste and the particle diameter of the silver particles. To form a transparent or translucent wire 400. In other examples of the present application, the conductive wire 400 may be formed of silver nanowires. Specifically, the silver nanowires can be formed by dispersing the silver nanowires in an organic solvent through processes including, but not limited to, spray coating and printing. In other examples of the present application, the conductive wire 400 may be formed of indium tin oxide (ITO). Therefore, by using the foregoing materials to form a conductive wire, the conductive wire can have good electrical conductivity without affecting the appearance of the routing area of the electrochromic device.
在本申请的一些示例中，第一电极层100和第二电极层300可以均由透明导电材料形成，由此，电致变色层产生的颜色可以从该电致变色器件的任一侧呈现出来。在本申请的一些示例中，第一电极层100和第二电极层300可以均由氧化铟锡形成。In some examples of the present application, the first electrode layer 100 and the second electrode layer 300 may both be formed of a transparent conductive material, so that the color generated by the electrochromic layer can be presented from either side of the electrochromic device . In some examples of the present application, the first electrode layer 100 and the second electrode layer 300 may each be formed of indium tin oxide.
在本申请的一些示例中，电致变色层200可以是由无机电致变色材料、有机小分子电致变色材料以及有机聚合物的至少之一构成的。由此，可以由上述多种材料形成电致变色层，使得电致变色层具有较广的材料来源。在本申请的一些示例中，无机电致变色材料可以为过渡金属氧化物、普鲁士蓝等，有机小分子电致变色材料可以为紫罗精类，有机聚合物可以为聚苯胺、聚噻吩等。In some examples of the present application, the electrochromic layer 200 may be composed of at least one of an inorganic electrochromic material, an organic small molecule electrochromic material, and an organic polymer. Therefore, the electrochromic layer can be formed from the foregoing multiple materials, so that the electrochromic layer has a wider source of materials. In some examples of the present application, the inorganic electrochromic material may be a transition metal oxide, Prussian blue, etc., the organic small molecule electrochromic material may be a violet, and the organic polymer may be polyaniline, polythiophene, or the like.
在本申请的一些示例中，导线400与柔性电路板500电连接，关于导线与柔性电路电连接的方式不受特别限制，只要二者之间具有良好的电连接性能即可，本领域技术人员可以根据具体情况进行设计。例如，在本申请的一些示例中，参考图3，导线400可以是通过导电胶600与柔性电路板500相连的。In some examples of the present application, the lead 400 is electrically connected to the flexible circuit board 500, and the manner of electrically connecting the lead to the flexible circuit is not particularly limited, as long as the two have good electrical connection performance, those skilled in the art Can be designed according to specific circumstances. For example, in some examples of the present application, referring to FIG. 3, the lead 400 may be connected to the flexible circuit board 500 through a conductive adhesive 600.
在本申请的一些示例中，参考图3，该电致变色器件还可以包括：第一基板700和第二基板800，其中，第一基板700设置在第一电极层100远离电致变色层200的一侧，第二基板800设置在第二电极层300远离电致变色层200的一侧，且第一基板700和第二基板800分别独立地由玻璃或塑胶形成。由此，电致变色层的颜色可以透过第一基板或者第二基板呈现出来。在本申请的一些示例中，构成上述基板的塑胶可以为聚对苯二甲酸乙二醇酯或者聚碳酸酯。In some examples of the present application, referring to FIG. 3, the electrochromic device may further include a first substrate 700 and a second substrate 800, wherein the first substrate 700 is disposed on the first electrode layer 100 away from the electrochromic layer 200. On one side, the second substrate 800 is disposed on the side of the second electrode layer 300 away from the electrochromic layer 200, and the first substrate 700 and the second substrate 800 are respectively formed of glass or plastic. Therefore, the color of the electrochromic layer can be displayed through the first substrate or the second substrate. In some examples of the present application, the plastic constituting the substrate may be polyethylene terephthalate or polycarbonate.
在本申请的一些示例中，参考图3，该电致变色器件还可以包括框胶900，框胶900包裹在电致变色层200的四周。换句话说，框胶900将电致变色层200密封在第一电极层和第二电极层之间。由此，可以利用框胶实现对该电致变色器件的封装，防止外界环境影响电致变色层的变色效果。In some examples of the present application, referring to FIG. 3, the electrochromic device may further include a frame adhesive 900, which is wrapped around the electrochromic layer 200. In other words, the sealant 900 seals the electrochromic layer 200 between the first electrode layer and the second electrode layer. Therefore, the sealant can be used to package the electrochromic device and prevent external environment from affecting the color changing effect of the electrochromic layer.
在本申请的一些示例中，参考图3，导线400设置在第一电极层100的边缘处并延伸至第一基板700上，导线400设置在第二电极层300的边缘处并延伸至第二基板800上(图中未示出导线在第二电极层上的情况)。由此，导线与基板以及电极层具有合适的接触面积，防止导线发生断裂，使导线具有良好的导通性能。In some examples of the present application, referring to FIG. 3, a lead 400 is disposed at an edge of the first electrode layer 100 and extends to the first substrate 700, and a lead 400 is disposed at an edge of the second electrode layer 300 and extends to the second On the substrate 800 (the case where the lead is on the second electrode layer is not shown in the figure). Therefore, the lead has a proper contact area with the substrate and the electrode layer, which prevents the lead from being broken, and the lead has a good conducting performance.
在本申请的一些示例中，参考图4，第一电极层100和第二电极层300的边缘处分别设置有导线400，导线400与柔性电路板500相连，且与第一电极层100相连的导线400，和与第二电极层300相连的导线400分别设置在该电致变色器件的两侧，通过导线400从电极层走线出来，实现电极层与外界控制电路的连接。需要说明的是，导线400分别与第一电极层100和第二电极层300相连，以在第一电极层100和第二电极层300之间形成用于变色的电场，也即是说，第一电极层100和第二电极层300并不能通过同一根导线400相连，图4仅是为了清楚的表示出与第一电极层100相连的导线，和与第二电极层300相连的导线之间的位置关系，而不能理解为两侧的导线均连接到第一电极层100上，实际上，图4中一侧的导线400与第一电极层100相连，另一侧的导线400与第二电极层300相连，第二电极层300位于第一电极层100远离第一基板700的一侧，以在两个电极层之间形成用于变色的电场。In some examples of the present application, referring to FIG. 4, wires 400 are respectively disposed at edges of the first electrode layer 100 and the second electrode layer 300. The wires 400 are connected to the flexible circuit board 500 and are connected to the first electrode layer 100. The lead 400 and the lead 400 connected to the second electrode layer 300 are respectively disposed on both sides of the electrochromic device, and are routed from the electrode layer through the lead 400 to realize the connection between the electrode layer and the external control circuit. It should be noted that the wire 400 is connected to the first electrode layer 100 and the second electrode layer 300, respectively, so as to form an electric field for discoloration between the first electrode layer 100 and the second electrode layer 300, that is, the first The electrode layer 100 and the second electrode layer 300 cannot be connected through the same wire 400. FIG. 4 is only for clearly showing the wires connected to the first electrode layer 100 and the wires connected to the second electrode layer 300. Positional relationship, it cannot be understood that the wires on both sides are connected to the first electrode layer 100. In fact, in FIG. 4, the wire 400 on one side is connected to the first electrode layer 100, and the wire 400 on the other side is connected to the second electrode layer 100. The electrode layers 300 are connected, and the second electrode layer 300 is located on a side of the first electrode layer 100 away from the first substrate 700 to form an electric field for changing colors between the two electrode layers.
在本申请的一些示例中，参考图5，第一电极层100和第二电极层300的边缘处还可以分别设置多根导线400，多根导线400均与柔性电路板500相连，多根导线400被配置为向第一电极层100和第二电极层300的多个区域(例如，图5中所示出的区域A、B、C、D、E、F)施加电压，形成多个可令电致变色层发生变色的电场，可以使该电致变色器件实现大区域变色或者局部区域变色或者多个区域的独立变色，使得该电致变色器件具有多彩的外观。需要说明的是，导线400分别与第一电极层100和第二电极层300相连，以在第一电极层100和第二电极层300之间形成用于变色的电场，也即是说，第一电极层100和第二电极层300并不能通过同一根导线400相连，图5仅是为了清楚的表示出与第一电极层100相连的多根导线，和与第二电极层300相连的多根导线之间的位置关系，而不能理解为两侧的导线均连接到第一电极层100上，实际上，图5中一侧的多根导线400与第一电极层100相连，另一侧的多根导线400与第二电极层300相连，第二电极层300位于第一电极层100远离第一基板700的一侧，以在两个电极层之间形成用于变色的电场。In some examples of the present application, referring to FIG. 5, a plurality of wires 400 may be respectively disposed at edges of the first electrode layer 100 and the second electrode layer 300, and the plurality of wires 400 are all connected to the flexible circuit board 500. 400 is configured to apply a voltage to a plurality of regions of the first electrode layer 100 and the second electrode layer 300 (for example, regions A, B, C, D, E, and F shown in FIG. 5) to form a plurality of possible regions. The electric field that causes the electrochromic layer to change color can cause the electrochromic device to achieve large area discoloration or local area discoloration or independent discoloration of multiple areas, so that the electrochromic device has a colorful appearance. It should be noted that the wire 400 is connected to the first electrode layer 100 and the second electrode layer 300, respectively, so as to form an electric field for discoloration between the first electrode layer 100 and the second electrode layer 300, that is, the first An electrode layer 100 and a second electrode layer 300 cannot be connected through the same wire 400. FIG. 5 is only for clearly showing a plurality of wires connected to the first electrode layer 100 and a plurality of wires connected to the second electrode layer 300. The positional relationship between the two wires cannot be understood as the wires on both sides are connected to the first electrode layer 100. In fact, in FIG. 5, multiple wires 400 on one side are connected to the first electrode layer 100, and the other side A plurality of wires 400 are connected to the second electrode layer 300. The second electrode layer 300 is located on a side of the first electrode layer 100 away from the first substrate 700 to form an electric field for changing colors between the two electrode layers.
在本申请的一些示例中，导线400的数量可以根据该电致变色器件变色区域的分区数量进行配置，以实现对电致变色层多个变色区域的独立控制，使得该电致变色器件实现多个区域的独立变色。换句话说，与第一电极层相连的导线的根数，与电致变色器件中变色区域的个数一致，同时与第二电极层相连的导线的根数，也与电致变色器件中变 色区域的个数一致。In some examples of the present application, the number of wires 400 may be configured according to the number of partitions of the color changing region of the electrochromic device, so as to achieve independent control of multiple color changing regions of the electrochromic layer, so that the electrochromic device achieves multiple Discoloration of each area. In other words, the number of wires connected to the first electrode layer is consistent with the number of discolored regions in the electrochromic device, and the number of wires connected to the second electrode layer is also the same as in the electrochromic device. The number of discolored areas is the same.
在本申请的一些示例中，柔性电路板500具有可弯折的特性，由此，利用导线电连接柔性电路板的方式从电极层上接线出来，可以使得电致变色器件的边框更窄，只保留柔性电路板与导线的触点即可。一方面，柔性电路板500的透明度要大于铜片，因此，在柔性电路板与导线的触点处更为透明，即从电致变色器件的上表面观察到的边框部分可以更为透明。另一方面，柔性电路板500具有柔性，与铜片相比，柔性电路板500除去其与导线400的触点处以外的部分，可以弯折到电致变色器件的背部，因此，电致变色器件的边框可以更窄。In some examples of the present application, the flexible circuit board 500 has a bendable characteristic. Therefore, wiring from the electrode layer by using a wire to electrically connect the flexible circuit board can make the frame of the electrochromic device narrower. Keep the contacts of the flexible circuit board and the wires. On the one hand, the transparency of the flexible circuit board 500 is greater than that of the copper sheet. Therefore, the contact between the flexible circuit board and the wires is more transparent, that is, the frame portion viewed from the upper surface of the electrochromic device can be more transparent. On the other hand, the flexible circuit board 500 has flexibility. Compared with a copper sheet, the flexible circuit board 500 can be bent to the back of the electrochromic device except for a portion other than the contact point with the lead 400, and therefore, the electrochromic The bezel of the device can be narrower.
在本申请的一些示例中，该电致变色器件可以包括多根导线400，多根导线400可以与同一个柔性电路板500相连，由此，可以实现多个区域的独立变色。换句话说，与第一电极层相连的多根导线均与一个柔性电路板相连，与第二电极层相连的多根导线均与另一个柔性电路板相连。也即是说，每个电极层仅需要设置一个柔性电路板即可(如图5所示)，柔性电路板上可以设置多个独立的连接点，上述连接点分别与电极层上各个区域的导线连接，便可实现对多个区域的分别控制，节省空间，且可以实现多个区域的独立变色。而目前通过铜片连接电极层的方式，若实现多个区域的独立变色，需要设置多个铜片，分别从电极层上引出，如前所述，一个铜片占用的空间已经很大，若实现多个区域的独立变色，势必将占用更多的空间，其也将不利于多个区域独立变色的实现，导致电致变色器件只能呈现单一的颜色。由此，本申请的电致变色器件与目前的电致变色器件相比，其走线方式更为简单、占用空间较小、边框较窄，且可以实现多个区域的独立变色，满足了用户对多彩外观的需求。In some examples of the present application, the electrochromic device may include a plurality of wires 400, and the plurality of wires 400 may be connected to the same flexible circuit board 500, thereby achieving independent color change in multiple regions. In other words, multiple wires connected to the first electrode layer are connected to one flexible circuit board, and multiple wires connected to the second electrode layer are connected to another flexible circuit board. In other words, each electrode layer only needs to be provided with a flexible circuit board (as shown in FIG. 5), and a plurality of independent connection points can be provided on the flexible circuit board, and the above connection points are respectively connected to the areas of the electrode layer. Wire connection can realize separate control of multiple areas, save space, and achieve independent color change in multiple areas. In the current method of connecting electrode layers through copper sheets, if independent color change in multiple areas is required, multiple copper sheets need to be provided, and each of them is led out from the electrode layer. As mentioned earlier, a copper sheet takes up a lot of space. Achieving independent color change in multiple regions will inevitably occupy more space, which will also be detrimental to the realization of independent color change in multiple regions, resulting in electrochromic devices that can only present a single color. Therefore, compared with the current electrochromic devices, the electrochromic device of the present application has a simpler wiring method, a smaller footprint, a narrower frame, and can achieve independent color change in multiple regions, satisfying users. The need for a colorful look.
