Description
Technical Field
The invention relates to the technical field of electrochromic, in particular to an electrochromic device and electronic equipment.
Background
In the current electrochromic device, voltage is generally applied to the electrochromic layer through the conductive layers at two sides of the electrochromic layer to realize the transmittance change of the electrochromic layer, so that in order to ensure the transparency of the conductive layer, the material of the conductive layer can be selected to be very limited, and Indium Tin Oxide (ITO) materials are generally adopted in the prior art. Although ITO is conductive, it is far less conductive than materials such as metals, and therefore, when electrochromic devices change color, there is typically a phenomenon that the periphery has begun to change color, but the center area has not changed color. Particularly in some larger size devices, it often takes seconds for the user to perceive that the edge begins to change color after the voltage is applied to the electrochromic device. In this case, it is difficult to timely determine whether the expected transmittance of the electrochromic device can achieve the desired effect of the user, thereby prolonging the waiting time of the user, and in addition, the user may misunderstand that the electrochromic device is not successfully started, thereby enabling the user to repeatedly operate, resulting in poor user experience.
In order to accelerate the color-changing response speed, the prior art generally adopts a mode of increasing the applied voltage, so that the edge of the electrochromic device changes color rapidly under the drive of high voltage. However, in this state, the edge of the electrochromic device is often in an overcharged state, and the lifetime of the electrochromic device is greatly reduced in long-term use.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.
Example 1
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 as including one second color-changing region 12 as an example), the first color-changing region 11 and each second color-changing region 12 being independently color-changeable, respectively, and for simultaneously changing colors according to the same target transmittance, wherein the area of the first color-changing region 11 is larger than the area of each second color-changing region 12.
Specifically, the display color-changing area of the electrochromic device may be divided into a first color-changing area 11 and at least one second color-changing area 12, where the first color-changing area 11 and each second color-changing area 12 may be controlled to change color independently, and the area of the first color-changing area 11 is larger than the area of each second color-changing area 12. The second color-changing region 12 can complete the color change more quickly when the first color-changing region 11 and the second color-changing region 12 are controlled to change colors using the same or similar voltages, respectively. When the electrochromic device provided in this embodiment is required to be used for color change, if the corresponding control signal is received, the control signal may carry a corresponding value of the target transmittance, and then the first color-changing area 11 and the second color-changing area 12 may be controlled to be respectively color-changed according to the target transmittance. Since the area of the second color-changing region 12 is smaller than that of the first color-changing region 11, and since the same target transmittance is used for both the second color-changing region 12 and the first color-changing region 11 and the second color-changing region 12 are the same or similar to each other (since the conductive layer used by the electrochromic device has a surface resistance and thus has a certain loss, 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), the second color-changing region 12 can reach the target transmittance faster to complete the color-changing process, and since the same target transmittance is used, the first color-changing region 11 and the second color-changing region 12 will also change to the same state finally without affecting the use of the electrochromic device. The second color-changing region 12 can be used as a preview region to provide faster feedback to the user during the color change using the electrochromic device so that the user knows that the electrochromic device has begun to respond to the color change and previews in advance the final state of the entire electrochromic device after the color change has been completed. The shape of the second color-changing region 12 may be circular, square, ring-shaped, bar-shaped, or the like.
Optionally, as shown in fig. 2, the number of the second color-changing areas 12 may be multiple, and 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 areas 12 are located at a more obvious position according to an actual use situation of the electrochromic device, so that a user can quickly obtain a preview result.
Optionally, the area ratio of the first color-changing area 11 to the second color-changing area 12 is greater than or equal to 10, further optionally, the area ratio of the first color-changing area 11 to the second color-changing area 12 is greater than or equal to 50, further optionally, the area ratio of the first color-changing area 11 to the second color-changing area 12 is greater than or equal to 100, so that the time required for the second color-changing area 12 to reach the target transmittance is shorter than that of the first color-changing area 11, the user can obtain the preview result faster, and the area ratio between the first color-changing area 11 and the second color-changing area 12 can be determined according to the size of the electrochromic device, so that the second color-changing area 12 can complete color change within the time range acceptable to the user.
Or alternatively, the area of the second color-changing area 12 is smaller than or equal to 0.1 square meter, that is, the area of the second color-changing area 12 is fixedly set to be smaller than or equal to 0.1 square meter regardless of the size of the electrochromic device, so that the second color-changing area 12 can be ensured to complete color changing within a time range acceptable to a user, that is, the second color-changing area 12 can be better used as a preview area for providing a preview function for the user for the electrochromic device with any size.
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 a position of the second color-changing area 12 and/or beside the second color-changing area 12 on the surface of the electrochromic device, and is used for marking a position of the second color-changing area 12. Specifically, when the electrochromic device is not in the process of changing color or after the process of changing color has been completed, because the color between the first color changing area 11 and the second color changing area 12 is consistent, it is difficult for the user to determine the specific position of the second color changing area 12, especially when the entire area of the electrochromic device is large, if the electrochromic device is required to change color, the attention of the user is difficult to be quickly focused on the second color changing area 12, so that the effect of the second color changing area 12 as a preview area is weakened. Therefore, the pattern layer can be arranged on the electrochromic device to indicate the position of the second color-changing area 12 to the user, and can be specifically arranged to be partially or completely overlapped with the second color-changing area 12 to accurately indicate the position of the second color-changing area 12, can also be arranged beside the second color-changing area 12 and point to the second color-changing area 12 to reduce shielding to the second color-changing area 12, so as to provide a clearer preview color-changing effect for the user, and can also be arranged beside the second color-changing area 12 and the second color-changing area 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 be respectively and independently changed in color 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 the preview area with a less region that discolours in the electrochromic device, when needs make electrochromic device take place to discolour, the preview area can be faster reach the target transmissivity to make the user can more timely know electrochromic device has started response discolour, and can be more quick preview reaches electrochromic device and accomplish the final state after discolour, promoted user's use experience greatly.

Specifically, the first etching groove 221 may enable the first conductive layer 22 to be divided into a plurality of conductive areas independent of each other, including a first conductive area corresponding to the first color-changing area and a second conductive area corresponding to the second color-changing area, that is, the first conductive area of the first color-changing area and the second conductive area of the second color-changing area are separated by the first etching groove 221, so that independent control of the first color-changing area and the second color-changing area can be achieved. The number of the first etching grooves 221 may be the same as the number of the second color change regions to obtain the same number of the second conductive regions.
Further optionally, as shown in fig. 4 and fig. 5, the electrochromic layer at the corresponding position of the first etching groove 221 may be partially or fully etched, so as to further ensure independent control between the first color-changing region and the second color-changing region.

The first color change region can be controlled to change color by applying voltages to the first extraction electrode 222 and the third extraction electrode 241, and the second color change region can be controlled to change color by applying voltages to the second extraction electrode 223 and the third extraction electrode 241, so that the first color change region and the second color change region can be independently changed.
Further alternatively, as shown in fig. 7, the second conductive layer 24 includes a second etched groove 242, where the second etched groove 242 is configured to divide the second conductive layer 24 into a third conductive area and a fourth conductive area that are independent of each other, where the third conductive area corresponds to the first color-changing area, and the fourth conductive area corresponds to the second color-changing area. Specifically, the second etching groove 242 may also divide the second conductive layer 24 into a plurality of conductive areas that are independent of each other, including a third conductive area corresponding to the first color-changing area and a fourth conductive area corresponding to the second color-changing area, that is, the third conductive area of the first color-changing area and the fourth conductive area of the second color-changing area are separated by the second etching groove 242, and correspond to the first conductive area and the second conductive area respectively, so that accuracy of independent control between the first color-changing area and the second color-changing area can be further improved. The number of second etched grooves 242 may be the same as the number of second color change 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 fully etched, so as to further ensure independent control between the first color-changing region and the second color-changing region.
