Background
Currently, in an electrochromic device, a voltage is generally applied to a conductive layer on two sides of an electrochromic layer to realize a transmittance change of the electrochromic layer, in order to ensure that the conductive layer is transparent, the material of the conductive layer that can be selected is very limited, and an Indium Tin Oxide (ITO) material is generally used in the prior art. Although ITO is conductive, it is far less conductive than metals, and thus when an electrochromic device changes color, it is common that the color of the periphery begins to change, but the color of the central area does not change. Especially in some larger size devices, it often takes several seconds for a user to detect the onset of edge discoloration after applying a voltage to the electrochromic device. Under the condition, whether the expected transmittance of the electrochromic device can achieve the ideal effect of a user or not is difficult to judge in time, so that the waiting time of the user is prolonged, and in addition, the user can mistakenly think that the electrochromic device is not started successfully, so that the user can operate repeatedly, and the user experience is poor.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Furthermore, the terms "first," "second," and the like may be used herein to describe various orientations, actions, steps, elements, or the like, but the orientations, actions, steps, or elements are not limited by these terms. These terms are only used to distinguish one direction, action, step or element from another direction, action, step or element. The terms "first", "second", etc. 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" or "second" may explicitly or implicitly include one or more of that feature.
Example one
Fig. 1 is a schematic structural diagram of an electrochromic device according to an embodiment of the present invention. As shown in fig. 1, the electrochromic device includes a first color-changing region 11 and at least one second color-changing region 12 (shown in fig. 1 by taking the example of including one second color-changing region 12), the first color-changing region 11 and each second color-changing region 12 can independently change color respectively and are used for simultaneously changing color according to the same target transmittance, wherein the area of the first color-changing region 11 is larger than that of each second color-changing region 12.
Specifically, the display color-changing region of the electrochromic device may be divided into a first color-changing region 11 and at least one second color-changing region 12, wherein the first color-changing region 11 and each second color-changing region 12 may be controlled to change color independently, and the area of the first color-changing region 11 is larger than the area of each second color-changing region 12. The second color-changing area 12 can complete color change more quickly when the same or similar voltage is used to control the first color-changing area 11 and the second color-changing area 12 to change color respectively. When the electrochromic device provided by the embodiment needs to be used for color changing, if the control signal can carry a corresponding target transmittance value when receiving a corresponding control signal, the first color-changing region 11 and the second color-changing region 12 can be simultaneously controlled to change color according to the target transmittance. Because the area of the second color-changing region 12 is smaller than that of the first color-changing region 11, and because both use the same target transmittance, the control voltages used correspondingly are the same or similar (the similarity is that the absolute value of the control voltage used by the first color-changing region 11 may need to be larger than that of the control voltage of the second color-changing region 12 because the conductive layer used by the electrochromic device has surface resistance, so that certain loss exists), therefore, the second color-changing region 12 can reach the target transmittance more quickly to complete the color-changing process, and because of using the same target transmittance, the first color-changing region 11 and the second color-changing region 12 will finally change to the same state without affecting the use of the electrochromic device. The second color-changing area 12 can be used as a preview area to more quickly feed back to the user during the process of using the electrochromic device to change color, so that the user knows that the electrochromic device has started to respond to the color change, and previews the final state of the entire electrochromic device after the color change is completed in advance. Wherein, the shape of the second color-changing region 12 can be circular, square, annular, and bar-shaped, etc.
Optionally, as shown in fig. 2, the number of the second color-changing regions 12 may be multiple, and the second color-changing regions may be distributed around the electrochromic device, and may also be disposed at a central position of the electrochromic device, so that the second color-changing regions 12 are located at obvious positions according to an actual use condition of the electrochromic device, thereby facilitating a user to obtain a preview result quickly.
Optionally, the area ratio of the first color-changing region 11 to the second color-changing region 12 is greater than or equal to 10, further optionally, the area ratio of the first color-changing region 11 to the second color-changing region 12 is greater than or equal to 50, and further optionally, the area ratio of the first color-changing region 11 to the second color-changing region 12 is greater than or equal to 100, so that the time required for the second color-changing region 12 to reach the target transmittance is shorter than that of the first color-changing region 11, so that a user can obtain a preview result more quickly, and the area ratio between the first color-changing region 11 and the second color-changing region 12 can be determined according to the size of the electrochromic device, so that the second color-changing region 12 can complete color change within a time range acceptable to the user.
Or optionally, the area of the second color-changing region 12 is smaller than or equal to 0.1 square meter, that is, regardless of the size of the electrochromic device, the area of the second color-changing region 12 is fixedly set to be smaller than or equal to 0.1 square meter, so that it is ensured that the second color-changing region 12 can complete color change within a time range acceptable by a user, that is, for an electrochromic device of any size, the second color-changing region 12 can be better used as a preview region to provide a preview function for the user.
On the basis of the above technical solution, optionally, the electrochromic device provided in this embodiment may further include a pattern layer, where the pattern layer is disposed at the position of the second color-changing region 12 and/or beside the second color-changing region 12 on the surface of the electrochromic device, and is used to mark the position of the second color-changing region 12. Specifically, when the electrochromic device is not in the color changing process or after the color changing process is completed, since the colors of the first color changing region 11 and the second color changing region 12 are consistent, it is difficult for a user to determine the specific position of the second color changing region 12, and particularly when the entire area of the electrochromic device is large, if the electrochromic device is required to change colors, the attention of the user is difficult to quickly concentrate on the second color changing region 12, so that the effect of the second color changing region 12 as a preview region is weakened. Therefore, a pattern layer can be arranged on the electrochromic device to indicate the position of the second color-changing region 12 to a user, the pattern layer can be specifically arranged to be partially or completely overlapped with the second color-changing region 12 to accurately indicate the position of the second color-changing region 12, can also be arranged beside the second color-changing region 12 and point to the second color-changing region 12 to reduce the shielding of the second color-changing region 12, so as to provide a clearer preview color-changing effect for the user, and can also be arranged beside the second color-changing region 12 and the second color-changing region 12 to provide a clearer indication effect for the user.
The electrochromic device provided by the embodiment of the invention comprises a first color-changing area and at least one second color-changing area, wherein the first color-changing area and each second color-changing area can independently change colors and are used for changing colors according to the same target transmittance, and the area of the first color-changing area is larger than that of each second color-changing area. Through regard as preview the region with a less discoloration area in the electrochromic device, when needs make the electrochromic device take place to change colour, the target transmittance that reaches that preview the region can be faster to make the user can be more timely know that the electrochromic device has begun to respond to and discolour, and can be faster preview to the electrochromic device and accomplish the final state after changing colour, promoted user's use greatly and experienced.

Specifically, the first etching groove 221 may divide the first conductive layer 22 into a plurality of conductive regions independent from each other, including a first conductive region corresponding to the first color-changing region and a second conductive region corresponding to the second color-changing region, that is, the first conductive region of the first color-changing region and the second conductive region of the second color-changing region are separated from each other by the first etching groove 221, so that the first color-changing region and the second color-changing region may be independently controlled. The number of the first etch grooves 221 may be the same as the number of the second discoloring regions to obtain the same number of second conductive regions.
As a further alternative, as shown in fig. 4 and 5, the electrochromic layer at the corresponding position of the first etching groove 221 may also be partially or completely etched, so as to further ensure independent control between the first color-changing region and the second color-changing region.
Further alternatively, as shown in fig. 6, the first conductive region is connected to the first extraction electrode 222, the second conductive region is connected to the second extraction electrode 223, and the second conductive layer 24 is connected to the third extraction electrode 241. The first color-changing region can be controlled to change color by applying voltage to the first lead electrode 222 and the third lead electrode 241, and the second color-changing region can be controlled to change color by applying voltage to the second lead electrode 223 and the third lead electrode 241, so that the first color-changing region and the second color-changing region can independently change color.
Further optionally, as shown in fig. 7, the second conductive layer 24 includes a second etching groove 242, and the second etching groove 242 is configured to divide the second conductive layer 24 into a third conductive region and a fourth conductive region that are independent of each other, where the third conductive region corresponds to the first color-changing region, and the fourth conductive region corresponds to the second color-changing region. Specifically, the second etching groove 242 may also divide the second conductive layer 24 into a plurality of conductive regions independent from each other, including a third conductive region corresponding to the first color-changing region and a fourth conductive region corresponding to the second color-changing region, that is, the third conductive region of the first color-changing region and the fourth conductive region of the second color-changing region are separated by the second etching groove 242 and respectively correspond to the first conductive region and the second conductive region, so that the accuracy of independent control between the first color-changing region and the second color-changing region may be further improved. The number of the second etching grooves 242 may be the same as the number of the second discoloring regions to obtain the same number of fourth conductive regions.
Further optionally, as shown in fig. 8 and fig. 9, the electrochromic layer at the corresponding position of the first etching groove 221 and the second etching groove 242 may be partially or completely etched, so as to further ensure independent control between the first color changing region and the second color changing region.

On the basis of the above technical solution, optionally, as shown in fig. 11, the second color-changing region 12 is disposed along an edge of the electrochromic device. When the second color-changing region 12 is disposed along the edge of the electrochromic device, the extraction electrodes (such as the second extraction electrode and the fifth extraction electrode) required by the conductive region corresponding to the second color-changing region 12 can be directly extracted from the edge of the electrochromic device, so that visual discomfort caused by the extraction electrodes can be avoided, and convenience in disposing the extraction electrodes is also improved.
According to the electrochromic device provided by the embodiment of the invention, the first etching groove is arranged on the first conducting layer of the electrochromic device so as to divide the first conducting layer into the first conducting area corresponding to the first color-changing area and the second conducting area corresponding to the second color-changing area, so that the independent control between the first color-changing area and the second color-changing area is realized. Furthermore, a second etching groove can be formed in a second conducting layer of the electrochromic device to divide the second conducting layer into a third conducting area corresponding to the first color changing area and a fourth conducting area corresponding to the second color changing area, and therefore accuracy of independent control between the first color changing area and the second color changing area is further improved.
