Background technique

Electrochromic devices generally apply voltage to the electrochromic layer through the conductive layers on both sides of the electrochromic layer to realize the change of the transmittance of the electrochromic layer. In order to ensure the transparency of the conductive layer, the materials that can be selected for the conductive layer are very limited. In the related art, indium tin oxide (ITO) material is generally used. Although ITO can conduct electricity, its conductivity is far less than that of metals and other materials. Therefore, when the electrochromic device changes color, it usually appears that the periphery has begun to change color, but the central area has not yet changed color. Especially in some larger devices, after applying voltage to the electrochromic device, it often takes several seconds for the user to notice that the edge starts to change color. In this case, it is difficult to judge in time whether the expected transmittance of the electrochromic device can achieve the desired effect of the user, thereby prolonging the waiting time of the user. In addition, it may make the user mistakenly believe that the electrochromic device has not been successfully activated. , so that the user repeats the operation, resulting in poor user experience.

In order to speed up the discoloration response speed, related technologies usually adopt a method 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 life of the electrochromic device will be greatly reduced under long-term use.

Fig. 1 is a schematic structural diagram of an electrochromic device provided by some embodiments of the present application. As shown in Figure 1, the electrochromic device includes a first color-changing region 11 and at least one second color-changing region 12 (shown as an example including a second color-changing region 12 in Figure 1), the first color-changing region 11 and Each second color-changing region 12 can change color independently, and is set to change color simultaneously 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 .

For example, the display color changing area of the electrochromic device can be divided into a first color changing area 11 and at least one second color changing area 12, wherein the first color changing area 11 and each second color changing area 12 can be controlled independently discoloration, and the area of the first discoloration region 11 is greater than the area of each second discoloration region 12 . When the same or similar voltage is used to control the first color changing region 11 and the second color changing region 12 to change color respectively, the second color changing region 12 can complete the color changing faster. When using the electrochromic device provided by this embodiment to change color, if the corresponding control signal is received, the control signal can carry the value of the corresponding target transmittance, then the first transmittance can be controlled simultaneously according to the target transmittance. The first discoloration area 11 and the second discoloration area 12 undergo discoloration respectively. Because the area of the second color-changing region 12 is smaller than that of the first color-changing region 11, and because the two use the same target transmittance, the corresponding control voltages used are the same or similar (the similarity is due to the conductive layer itself used by the electrochromic device. There is area resistance, so there is a certain loss, so the absolute value of the control voltage used by the first color-changing region 11 may need to be greater than the absolute value of the control voltage of the second color-changing region 12), therefore, the second color-changing region 12 can be faster To achieve the target transmittance to complete the process of color change, and because the same target transmittance is used, the first color-changing region 11 and the second color-changing region 12 will eventually change to the same state without affecting the electrochromic device. use. The second color-changing area 12 can be used as a preview area. In the process of using the electrochromic device to change color, it can give feedback to the user faster, so that the user can know that the electrochromic device has begun to respond to the color change, and preview the entire electrochromic device in advance.

Or for example, the area of the second color-changing region 12 is less than or equal to 0.1 square meters, that is, regardless of the size of the electrochromic device, the area of the second color-changing region 12 is fixed to be less than or equal to 0.1 square meters, thereby ensuring that the second color-changing region 12 The discoloration can be completed within a time range acceptable to the user, that is, for an electrochromic device of any size, the second discoloration region 12 can preferably be used as a preview region to provide users with a preview function.

For example, after the user determines the target transmittance by selecting the area 51 , the electrochromic device can generate a control signal to simultaneously control the preview area 53 and the dimming area 52 to start to change color according to the target transmittance. Because the area of the preview area 53 is smaller than the area of the dimming area 52, the preview area 53 can complete the discoloration faster, thereby providing the user with a fast preview function to give feedback to the user, so that the user knows that the electrochromic device has started Response to color change, thereby avoiding repeated operations by users, greatly improving the user experience. In one embodiment, the area ratio of the dimming area 52 to the preview area 53 is greater than or equal to 100, so that the time required for the preview area 53 to change color can be greatly shortened, so as to provide users with a preview function faster.

In some embodiments, the distance between the preview area 53 and the selection area 51 is less than a preset distance, that is, the preview area 53 can be set near the selection area 51, so that the user can see the transmittance pattern displayed according to the selection area 51. While selecting the target transmittance, the change of the transmittance in the preview area 53 can be observed conveniently, so that the preview function provided by the preview area 53 can be better used.

Some embodiments of the present application provide a method for controlling an electrochromic device. This embodiment can control the electrochromic device to change color according to the needs of users. This method can be executed by the control device of the electrochromic device provided in the embodiment of the application. The device can be implemented by hardware and/or software. It can be integrated into computer equipment, and the computer equipment is not limited to the electrochromic device itself or other remote control terminals. Including the following steps:

S11. Monitor the variation of the characteristic value of the dimming area on the electrochromic device, wherein the variation of the characteristic value includes at least one of the variation of the voltage value and the variation of the current value.

Wherein, the electrochromic device may include a dimming area, which can be used to change color according to the target transmittance required by the user, that is, the main functional area of the electrochromic device. During the use of the electrochromic device, it can be determined whether the electrochromic device starts to work normally by monitoring the variation of the characteristic value in the dimming area. For example, the variation of the characteristic value can be the variation of the voltage value and/or the variation of the current value, etc., and the electrochromic device can realize the change of the transmittance of the electrochromic layer wherein by applying a voltage. Therefore, when the electrochromic device When working, the dimming area will produce changes in characteristic values such as voltage or current values, thereby changing the color. When the area of the electrochromic device is large, the color change of the dimming area will be slower, but the real-time characteristic value change of the dimming area can still be obtained relatively quickly, so as to facilitate subsequent steps.

S12. Comparing the variation of the characteristic value with the preset value, and controlling the preview region corresponding to the dimming region to change color according to the preset transmittance pattern in response to the variation of the characteristic value being greater than the preset value.

For example, the eigenvalue variation of the dimming area can be obtained in real time, where the eigenvalue variation is a positive value, that is, the absolute value of the eigenvalue variation, and after each acquisition, the current eigenvalue variation and the predicted Compared with the set value, when the variation of the characteristic value is greater than the preset value, it can be determined that the dimming area has begun to change color in response. At this time, the preview area corresponding to the dimming area can be controlled to change color according to the preset transmittance pattern. Among them, the preview area can complete the color change faster than the dimming area to provide users with a preview function. When the area of the electrochromic device is large, the dimming area may take a long time to make the user notice that its edge begins to change color. , when it is determined that the dimming area starts to change color through the change of the characteristic value of the dimming area, the rapid discoloration of the preview area can be controlled, so that the user can know in a timely manner that the electrochromic device has begun to respond to discoloration, thereby avoiding repeated operations by the user .

In some embodiments, the preview area is located on the electrochromic device or on a remote control terminal outside the electrochromic device. For example, the variable color area on the electrochromic device can include a dimming area and a preview area, and the dimming area and the preview area can change color independently, so that users can be provided with a preview function directly through the electrochromic device. Applying a preset voltage to the preview area controls the preview area to change color according to a preset transmittance pattern. Or, the preview area can be located on the remote control terminal outside the electrochromic device, for example, it can be an electrochromic component or a display area on the terminal screen. When the preview area is an electrochromic component, the preview area can also be Apply a preset voltage to control the preview area to change color according to the preset transmittance style. When the preview area is a display area on the terminal screen, the preview area can be controlled according to the preset transmittance by pre-stored pixel values and other data The style changes color. By setting the preview area on the remote control terminal, the remote control of the electrochromic device can be realized, and it is convenient for the user to confirm in time that the electrochromic device has begun to respond to discoloration directly through the remote control terminal. The so-called electrochromic component here means that the preview area can be a separate electrochromic device, for example, it can independently include the first base layer, the first conductive layer, the electrochromic layer, the second The second conductive layer and the second base layer, so that a preset voltage can be applied to control the electrochromic component (that is, the preview area) to change color according to a preset transmittance pattern.

In some embodiments, before controlling the preview area corresponding to the dimming area to change color according to the preset transmittance pattern, it also includes: acquiring a control signal of the dimming area; determining the preset transmittance pattern according to the control signal, to Make the color of the preview area the same as that of the dimming area after the color change is completed.

For example, the control signal may carry an expected transmittance value or a control voltage of the dimming area, and the preset transmittance pattern of the preview area may be determined according to the control signal. Exemplarily, when the preview area is located on the electrochromic device or is the above-mentioned electrochromic component, the preview area can be directly changed to the preset transmittance pattern by applying the same control voltage as the dimming area, exemplary Yes, in order to make the preview area change color faster than the dimming area, the area of the preview area can be much smaller than the area of the dimming area. For example, the area ratio of the dimming area to the preview area can be set to be greater than or equal to 100. However, due to the surface resistance of the conductive layer used in the electrochromic device, there is a certain loss. Therefore, if you want to make the preview area and the dimming area have the same color after the color change, you may need to apply different voltages respectively, that is The absolute value of the control voltage of the preview area may be smaller than the absolute value of the control voltage of the dimming area, then the expected transmittance value of the dimming area can be determined according to the control signal of the dimming area, and used as the expected transmittance of the preview area transmittance pattern, and use the control voltage of the preview area corresponding to the expected transmittance pattern to control the preview area to change color. When the preview area is the above terminal screen display area, the expected transmittance value of the dimming area can be determined according to the control signal of the dimming area, and used as the expected transmittance pattern of the preview area, and then the expected transmittance value can be determined according to the expected transmittance pattern It can be displayed on the screen. In an embodiment, the corresponding relationship between the control voltage of the dimming area and the expected transmittance pattern can also be stored in advance, then when the control preview area changes color, the corresponding expected transmittance can be found directly according to the control voltage of the dimming area. Override the style and display it on the screen. By making the color change in the preview area the same as that in the dimming area, the user can quickly preview the final state of the electrochromic device after the color change, and determine whether it can meet the user's expectations in a timely manner. The adjustment avoids long waiting and greatly improves the user experience.

In some embodiments, the control method of the electrochromic device further includes: monitoring whether the dimming area reaches a preset cut-off condition, and in response to the dimming area reaching the preset cut-off condition, stopping applying voltage to the dimming area or adopting a preset The hold voltage maintains the transmittance in the dimming area. For example, after it is determined that the variation of the characteristic value of the dimming area is greater than the preset value, that is, after it is determined that the dimming area begins to respond to discoloration, it is possible to monitor whether the dimming area reaches the preset cut-off condition, and respond to the dimming area reaching the preset cut-off condition , stop applying voltage to the dimming area or adopt a small preset holding voltage to maintain the transmittance of the dimming area, so that the dimming area is stabilized at the expected transmittance value. Wherein, the preset cut-off condition may be that the current is less than or equal to the preset cut-off current, the voltage application time is greater than or equal to the preset time, or the unit charge capacity of the charging process reaches a preset value, and the like. Similarly, when the preview area is located on the electrochromic device or is the above-mentioned electrochromic component, it is also possible to monitor whether the preview area reaches the preset cut-off condition after starting to control the preview area to change color, and when it reaches the preset cut-off condition Stop applying voltage to the preview area or use a preset holding voltage to maintain the transmittance of the preview area.

In the embodiment of the present application, firstly, the variation of the characteristic value of the dimming area on the electrochromic device is monitored, and then the variation of the characteristic value is compared with the preset value. In response to the variation of the characteristic value being greater than the preset value, the The transmittance style controls the color change of the preview area corresponding to the dimming area. By monitoring the change of the characteristic value on the dimming area, it is determined that the dimming area starts to change color, and when the dimming area starts to change color, the preview area is controlled to start to change color, so as to realize the preview function, so that the user can know in time that the electrochromic device has started Responsive color change avoids repeated user operations, thus greatly improving the user experience. At the same time, by triggering the color change of the preview area after it is determined that the dimming area starts to change color, it also avoids situations such as the independent color change of the preview area and the false triggering of the preview area when the dimming area fails to change color, thereby improving the accuracy of the function of the preview area sex.

When the sensor is used to determine the start, it can also be used when the user approaches for more than a preset time (such as 30 seconds) and does not operate In this case, the selected area is hidden again, that is, the transmittance of the selected area is adjusted to be consistent with the transmittance of the dimming area. Wherein, the sensor may be an infrared sensing probe or the like.
