Abstract

An electrochromic device control method and apparatus, an electronic device, and a storage medium. The electrochromic device control method comprises: acquiring parameter information of an electrochromic device (101); determining a target electricity accumulation on the basis of the parameter information, wherein the target electricity accumulation is used for representing a uniform color distribution of a color changing layer of the electrochromic device at different positions (102); and inputting a target time-varying signal corresponding to the target electricity accumulation into an electrochromic controller, wherein the electrochromic controller is used for inputting the target time-varying signal into a conductive layer of the electrochromic device, so that the conductive layer controls the color of the color changing layer on the basis of the time-varying signal (103). Since the target time-varying signal can inhibit the color changing speed of the edge of the color changing layer in the electrochromic device such that the color changing speed of the edge of the color changing layer is closer to the color changing speed of the middle of the color changing layer, inputting the target time-varying signal into the conductive layer of the electrochromic device can achieve a more uniform color changing effect of the electrochromic device.

相关技术中，电致变色器件中的电致变色材料在外加电流或电场的作用下，外部离子在电致变色材料中注入或抽出，材料发生可逆的电化学反应，导致材料的光学属性(包括反射率、吸收率及透射率)发生变化，进而材料在外观上表现出颜色和透明度的可逆变化。In the related art, under the action of an external current or electric field, external ions are injected into or extracted from the electrochromic material in the electrochromic device, and the material undergoes a reversible electrochemical reaction, resulting in changes in the optical properties of the material (including reflectivity, absorptivity and transmittance), and the material then exhibits a reversible change in color and transparency in appearance.
但是，由于电致变色器件中的导电层本身存在面阻，电压在电致变色器件上分布是不均匀的，即电压从边缘向中心逐渐降低，这会导致变色速度不一致，边缘快中心慢，影响电致变色器件的变色效果。However, due to the surface resistance of the conductive layer in the electrochromic device itself, the voltage is unevenly distributed on the electrochromic device, that is, the voltage gradually decreases from the edge to the center, which will cause inconsistent color change speeds, faster at the edge and slower in the center, affecting the color change effect of the electrochromic device.
因此，如何避免电致变色器件变色速度不一致，进而提升变色效果是亟待解决的问题。Therefore, how to avoid inconsistent color change speeds in electrochromic devices and thereby improve the color change effect is an urgent problem to be solved.

具体实施方式Detailed ways
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
为了便于更加清晰地理解本申请各实施例，首先对一些相关的背景知识进行如下介绍。In order to facilitate a clearer understanding of the embodiments of the present application, some relevant background knowledge is first introduced as follows.
电致变色材料是指在外加电流或电场的作用下，外部离子在电致变色材料中注入或抽出，材料发生可逆的电化学反应，导致材料的光学属性(包括反射率、吸收率及透射率)发生变化，进而材料在外观上表现出颜色和透明度的可逆变化。Electrochromic materials refer to materials in which external ions are injected or extracted under the action of an applied current or electric field, causing a reversible electrochemical reaction in the material, resulting in changes in the material's optical properties (including reflectivity, absorptivity and transmittance), and the material's appearance then exhibits a reversible change in color and transparency.
现有技术中，电致变色器件几乎都有一个一致的结构：即最外部是一上一下两层透明导电层，可外接电极提供电压和电流；中间夹着变色层、离子存储层、离子输运层等功能性膜层。对不同材料的电致变色器件而言，其中间各层的层数、材料、厚度、制备方法多种多样，但整体器件结构是相同的。In the prior art, electrochromic devices almost all have a consistent structure: the outermost layer is a transparent conductive layer, one above and one below, which can be connected to an external electrode to provide voltage and current; in the middle are functional film layers such as a color-changing layer, an ion storage layer, and an ion transport layer. For electrochromic devices made of different materials, the number of layers, materials, thickness, and preparation methods of the intermediate layers vary, but the overall device structure is the same.
通过对上下导电层施加合适的电压可以调节电致变色器件的透明度。通 常，对器件施加的是直流电压、由极性变化来实现器件的着色和褪色，比如，正压着色、负压褪色。The transparency of the electrochromic device can be adjusted by applying a suitable voltage to the upper and lower conductive layers. Usually, a DC voltage is applied to the device, and the coloring and fading of the device are achieved by changing the polarity, for example, positive voltage for coloring and negative voltage for fading.
但是，这种控制方式存在着一个较大的问题：由于导电层本身存在面阻，电压在器件上分布是不均匀的，从边缘向中心逐渐降低，这会导致变色速度不一致，边缘快中心慢，影响产品效果；甚至，如果压降过大，可能造成边缘电压已超过材料极限而中心电压还未达到最低变色要求，这将限制器件的最大尺寸。However, this control method has a big problem: due to the surface resistance of the conductive layer itself, the voltage is unevenly distributed on the device, gradually decreasing from the edge to the center, which will lead to inconsistent color change speeds, with faster edges and slower centers, affecting product effects; even if the voltage drop is too large, the edge voltage may exceed the material limit while the center voltage has not yet reached the minimum color change requirement, which will limit the maximum size of the device.
综上所述，针对上述存在的技术问题，本申请实施例提供一种电致变色器件的控制方法、装置、电子设备及存储介质，从而避免电致变色器件变色速度不一致的问题，进而提升电致变色器件的变色效果。In summary, in response to the above-mentioned technical problems, the embodiments of the present application provide a control method, device, electronic device and storage medium for an electrochromic device, thereby avoiding the problem of inconsistent color changing speed of the electrochromic device and further improving the color changing effect of the electrochromic device.

步骤101、获取所述电致变色器件的参数信息。Step 101: Obtain parameter information of the electrochromic device.
首先需要说明的是，本申请的执行主体可以是具有电致变色器件控制功能的任何电子设备，例如可以为智能手机、智能手表、台式电脑、手提电脑等任何一种；在实际应用中，执行主体基于电致变色器件的参数信息生成目标时变信号，并将目标时变信号输入至电致变色器控制器，进一步地，电致变色器控制器将目标时变信号施加在电致变色器件的导电层，以使导电层基于时变信号对电致变色器件的变色层的颜色进行控制。First of all, it should be explained that the execution subject of the present application can be any electronic device with the function of controlling an electrochromic device, for example, it can be any one of a smart phone, a smart watch, a desktop computer, a laptop computer, etc.; in actual applications, the execution subject generates a target time-varying signal based on the parameter information of the electrochromic device, and inputs the target time-varying signal to the electrochromic controller.

为了避免电致变色器件变色速度不一致，进而提升电致变色器件的变色效果，在本实施例中，首先需要获取电致变色器件的参数信息。In order to avoid inconsistent color changing speed of the electrochromic device and thus improve the color changing effect of the electrochromic device, in this embodiment, it is first necessary to obtain parameter information of the electrochromic device.
在实际应用中，获取到电致变色器件的参数信息之后，即可利用参数信息在数值仿真软件(例如COMSOL Multiphysics)中构建出电致变色器件的器件结构。In practical applications, after obtaining the parameter information of the electrochromic device, the parameter information can be used to construct the device structure of the electrochromic device in numerical simulation software (such as COMSOL Multiphysics).

在本实施例中，在获取到参数信息之后，需要基于参数信息，计算在不同输入电压下电致变色器件的电量积累，其中，电量积累用于表征电致变色器件的变色层在不同位置上的变色程度。In this embodiment, after the parameter information is obtained, it is necessary to calculate the power accumulation of the electrochromic device under different input voltages based on the parameter information, wherein the power accumulation is used to characterize the degree of color change of the color-changing layer of the electrochromic device at different positions.
然后再各电量积累中确定出目标电量累积，以使变色层在不同位置上的颜色分布均匀。Then, the target power accumulation is determined in each power accumulation so that the color distribution of the color-changing layer at different positions is uniform.
步骤103、将所述目标电量累积对应的目标时变信号输入电致变色控制器；所述电致变色控制器用于将所述目标时变信号输入所述电致变色器件的导电层，以使所述导电层基于所述时变信号对所述变色层的颜色进行控制。 Step 103, inputting a target time-varying signal corresponding to the target power accumulation into an electrochromic controller; the electrochromic controller is used to input the target time-varying signal into the conductive layer of the electrochromic device, so that the conductive layer controls the color of the color-changing layer based on the time-varying signal.
在本实施例中，目标时变信号随时间变化，且目标时变信号可表达为三角函数如正弦、余弦的形式，也可以为方波的形式。In this embodiment, the target time-varying signal varies with time, and the target time-varying signal can be expressed in the form of a trigonometric function such as sine and cosine, or in the form of a square wave.
本申请提供的电致变色器件的控制方法，通过电致变色器件的参数信息，确定出可以使电致变色器件的变色层能够在不同位置上颜色分布均匀的目标电量积累；由于目标电量积累对应的目标时变信号可以抑制电致变色器件中 变色层边缘的变色速度，使得变色层边缘变色速度和变色层中间的变色速度更趋近于抑制，因此将目标时变信号输入电致变色控制器，电致变色控制器将时变信号输入电致变色器件的导电层，进而可以实现电致变色器件更均匀的变色效果；另外，目标时变信号同样避免了由于压降过大，进而造成电致变色器件边缘电压已超过材料极限但是中心电压还未达到最低变色要求的问题，进而在一定程度上解决了电致变色器件尺寸受限的问题。The control method of the electrochromic device provided in the present application determines the target power accumulation that can make the color-changing layer of the electrochromic device evenly distributed in different positions through the parameter information of the electrochromic device; because the target time-varying signal corresponding to the target power accumulation can suppress the color-changing speed at the edge of the color-changing layer in the electrochromic device, so that the color-changing speed at the edge of the color-changing layer and the color-changing speed in the middle of the color-changing layer are closer to being suppressed, the target time-varying signal is input into the electrochromic controller, and the electrochromic controller inputs the time-varying signal into the conductive layer of the electrochromic device, thereby achieving a more uniform color-changing effect of the electrochromic device; in addition, the target time-varying signal also avoids the problem that the edge voltage of the electrochromic device has exceeded the material limit but the center voltage has not reached the minimum color-changing requirement due to excessive voltage drop, thereby solving the problem of limited size of the electrochromic device to a certain extent.
可选地，在本申请实施例一种可能的实现方式中，所述基于所述参数信息，确定目标电量累积，可以通过以下方式实现，具体包括步骤[1]-步骤[2]：Optionally, in a possible implementation of the embodiment of the present application, determining the target power accumulation based on the parameter information may be implemented in the following manner, specifically including steps [1] to [2]:
步骤[1]、基于所述参数信息，确定所述电致变色器件的电流分布函数；Step [1], determining a current distribution function of the electrochromic device based on the parameter information;
步骤[2]、基于所述电流分布函数及时变信号参数，确定所述目标电量累积。Step [2]: Determine the target power accumulation based on the current distribution function and the time-varying signal parameters.
在本实施例中，首先需要基于参数信息，在不同的输入电压下，通过数值仿真软件进行仿真，得到电致变色器件的电流分布函数i(x,t)，其中，电流分布函数用于表征电致变色器件中电压和电流的分布。In this embodiment, it is first necessary to perform simulation using numerical simulation software based on parameter information at different input voltages to obtain the current distribution function i(x, t) of the electrochromic device, wherein the current distribution function is used to characterize the distribution of voltage and current in the electrochromic device.
在得到电流分布函数之后，通过对时变信号参数进行调整，基于电流分布函数，即可在不同的电量累积中确定出在电致变色器件中分布尽可能均匀的目标电量累积，其中，目标电量累积用于表征电致变色器件的变色层在不同位置上的颜色分布均匀。After obtaining the current distribution function, by adjusting the time-varying signal parameters, based on the current distribution function, the target electric quantity accumulation that is distributed as evenly as possible in the electrochromic device can be determined from different electric quantity accumulations, wherein the target electric quantity accumulation is used to characterize the uniform color distribution of the color-changing layer of the electrochromic device at different positions.
也就是说，通过在仿真软件中尝试不同的时变信号参数组合，使得电量累积尽可能均匀分布，即可得到目标电量积累。In other words, by trying different combinations of time-varying signal parameters in the simulation software, the target power accumulation can be obtained by making the power accumulation as evenly distributed as possible.
需要说明的是，对电流分布函数的时间t进行积分，即可得到不同输入电压下的电量累积，具体可以通过以下公式(2)表示：It should be noted that by integrating the time t of the current distribution function, the accumulated electricity under different input voltages can be obtained, which can be specifically expressed by the following formula (2):
Figure PCTCN2022138484-appb-000001
Figure PCTCN2022138484-appb-000001
其中，Q(x)表示电量累积；i(x,t)表示电流分布函数。Among them, Q(x) represents the accumulated charge; i(x,t) represents the current distribution function.
可选地，在本申请实施例一种可能的实现方式中，所述时变信号参数包括以下任一项：Optionally, in a possible implementation manner of the embodiment of the present application, the time-varying signal parameter includes any one of the following:
a)时变信号的固定电压V 0； a) Fixed voltage V 0 of time-varying signal;
a)时变信号的振幅V 1； a) Amplitude V 1 of the time-varying signal;
a)角频率ω。a) Angular frequency ω.
在上述实施方式中，通过对时变信号参数进行调整，即可确定出在电致变色器件中分布尽可能均匀的目标电量累积，由于目标电量积累对应的目标时变信号可以抑制电致变色器件中变色层边缘的变色速度，使得变色层边缘变色速度和变色层中间的变色速度更趋近于抑制，因此将目标时变信号输入电致变色器件的导电层，进而可以实现电致变色器件更均匀的变色效果。In the above-mentioned embodiment, by adjusting the time-varying signal parameters, the target electric quantity accumulation that is distributed as evenly as possible in the electrochromic device can be determined. Since the target time-varying signal corresponding to the target electric quantity accumulation can suppress the color change speed at the edge of the color change layer in the electrochromic device, the color change speed at the edge of the color change layer and the color change speed in the middle of the color change layer are closer to being suppressed. Therefore, the target time-varying signal is input into the conductive layer of the electrochromic device, thereby achieving a more uniform color change effect of the electrochromic device.
可选地，在本申请实施例一种可能的实现方式中，所述目标时变信号可以通过以下公式(1)表示：Optionally, in a possible implementation of the embodiment of the present application, the target time-varying signal can be expressed by the following formula (1):
V(t)＝V 0+V 1sin(2πωt)       (1) V(t)＝V 0 +V 1 sin(2πωt) (1)
其中，V(t)表示所述目标时变信号；V 0表示所述目标时变信号的固定电压；V 1表示所述目标时变信号的振幅；ω表示所述目标电压的角频率。 Wherein, V(t) represents the target time-varying signal; V0 represents the fixed voltage of the target time-varying signal; V1 represents the amplitude of the target time-varying signal; and ω represents the angular frequency of the target voltage.
