[0018] Thirdly, a controller is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of the above-described method.

[0019] Fourthly, a stacked assembly is provided, comprising: a transparent substrate, a first functional layer and a second functional layer disposed on the transparent substrate, and a controller as described above;

[0020] The first functional layer includes a first conductive layer and a second conductive layer stacked together, wherein the second conductive layer is closer to the second functional layer than the first conductive layer.

[0021] The controller is electrically connected to the first conductive layer and the second conductive layer, respectively.

[0022] In one embodiment, the transparent substrate includes a first substrate layer and a second substrate layer disposed opposite to each other, and the first substrate layer and the second substrate layer form a sandwich space.

[0023] Both the first functional layer and the second functional layer are disposed in the interlayer space and are disposed directly or indirectly on the first substrate layer or the second substrate layer.

[0024] In one embodiment, the controller includes a power supply terminal, a ground terminal, a first output terminal, and a second output terminal; the ground terminal is used to connect to a ground signal.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0050] The control method provided in this application embodiment can be applied to, for example, Figure 1In the application environment shown, the stacked component includes a controller 20, a first functional layer 40, and a second functional layer 60. The controller 20 is electrically connected to the first functional layer 40, which includes at least a first conductive layer 42 and a second conductive layer 46 arranged sequentially. The controller 20 communicates with the first conductive layer 42 and the second conductive layer 46, providing driving voltages to drive the first functional layer 40 to perform its functions. For example, the first functional layer 40 may include a dimming layer 44. The voltage provided by the first conductive layer 42 and the second conductive layer 46 can drive changes in the transparency of the dimming layer 44, thereby changing the transparency of the stacked component.

[0051] The second functional layer 60 may be a conductive layer containing metal. The conductive layer may be a layer structure containing metallic elements, such as a metal film. Of course, the conductive layer is not limited to a film formed by a single metal such as copper film. It may also be a film containing conductive material, composed of continuously distributed materials, or have a grid-like or other spaced structure.

[0052] For example, conductive layers such as silver plating, low-emissivity (LOW-E) layers, heat insulation layers, radiation-resistant layers, sound insulation layers, and light-regulating layers can all be used as secondary functional layers. Among them, the LOW-E layer can be made of various metals and has good heat insulation and light transmittance.

[0053] Therefore, the first conductive layer 42, the second conductive layer 44, and the second functional layer 60 can all be considered conductors. Since insulating media such as air or a dimming layer may exist between them, they can form capacitors. Therefore, when alternating current flows through the first functional layer 40, the second functional layer 60 also becomes charged. When a user touches the second functional layer 60, the electricity on the second functional layer 60 is grounded through the human body, and the human body senses the current flowing through it, resulting in an electric shock. Therefore, how to reduce the induced voltage on the second functional layer 60 is an urgent problem to be solved.

[0054] To address the above problems, in one embodiment, such as Figure 2 As shown, a control method is provided, the method comprising:

[0055] S204, a first electrical signal is applied to the first conductive layer of the first functional layer in the stacked component.

[0056] S206, a second electrical signal is applied to the second conductive layer of the first functional layer. The second electrical signal has the same frequency as the first electrical signal but opposite in direction. The opposite direction can be understood as the waveform opening direction being opposite.

[0057] The second conductive layer is closer to the second functional layer of the stacked component than the first conductive layer, and the effective voltage value of the second electrical signal is less than the effective voltage value of the first electrical signal, so as to reduce the induced electricity on the second functional layer.

[0058] In this system, both the first and second electrical signals are alternating current (AC). The first functional layer can perform functions under the drive of the first and second electrical signals. For example, the first functional layer can perform functions such as dimming and temperature adjustment. When the AC current applied to the first functional layer changes, its light transmittance, light absorption, and light reflectance can change accordingly, thereby altering its color or temperature.

[0059] Specifically, by applying a smaller effective voltage to the second conductive layer located near the second functional layer, and adding a square wave signal (as in traditional technologies) to the first conductive layer, the function of the first functional layer can be supported based on the fact that the two have the same frequency and opposite directions. At the same time, the effective value of the induced voltage on the second functional layer is reduced. Without affecting the function of the first functional layer, the induced voltage of the second functional layer is reduced, thereby improving the electric shock situation when the user touches the second functional layer.

[0060] Furthermore, this implementation method only requires changing the control logic to reduce the effective value of the induced voltage on the second functional layer. This allows for upgrades and modifications to existing multilayer modules without altering their wiring structure, facilitating the transformation of already manufactured multilayer modules.

[0061] In one embodiment, such as Figures 3a-3c As shown, the first electrical signal is a square wave signal, and the second electrical signal is a half-wave signal or a sawtooth wave signal.

[0062] In this design, the half-wave signal contains two half-waves within a single cycle, with adjacent half-waves exhibiting opposite directions. Since the effective voltage values ​​of both the half-wave and sawtooth wave signals are smaller than those of the square wave signal, the first and second electrical signals are jointly applied to the first functional layer to achieve sinusoidal AC drive. The appropriate first and second electrical signals can be selected based on the driving requirements of the first functional layer. Overall, the principle is that the first and second electrical signals have the same frequency and opposite directions, and the effective voltage value of the first electrical signal is greater than that of the second electrical signal.

[0063] In one embodiment, the first functional layer further includes a dimming layer, and a first electrical signal and a second electrical signal are used to jointly drive the dimming layer. The dimming layer may be made of one or more of the following materials, including but not limited to PDLC (polymer dispersed liquid crystal), SPD (Suspended Particle Device), GHLC (Guest-Host Liquid Crystal), EC (Electrochromic Device), LC (liquid crystal), LED (light-emitting diode), heat-insulating film, color-changing film, light-guiding film, and display film.

[0064] For example, when the material of the dimming layer includes PDLC, the dimming layer is a polymer-dispersed liquid crystal layer. By applying an alternating voltage to the first conductive layer and the second conductive layer, the liquid crystal molecules are flipped to achieve the effect of adjusting the glass haze (which corresponds to the transparency). When the first functional layer includes SPD, the dimming layer is a suspended particle layer. Of course, the first functional layer may also include a first substrate layer and a second substrate layer respectively disposed outside the first conductive layer and the second conductive layer to support the first functional layer. The layers of the first functional layer can be combined by means of bonding or other methods.

[0065] In one embodiment, the control method further includes:

[0066] In transparency mode, the effective value of the voltage of the second electrical signal is adjusted according to the target transparency to match the target transparency.

[0067] In transparent mode, transparency can be adjusted steplessly or in stages. For example, a mapping curve can be pre-stored, where each level of transparency corresponds to an effective value of a second electrical signal, allowing for stepless adjustment. Alternatively, a mapping table can be pre-stored, containing at least two columns of data types: transparency and the effective voltage value of the second electrical signal. Each row of the table contains a set of transparency and effective voltage values. Based on the target transparency, the matching effective voltage value of the second electrical signal can be determined by looking up the table. In stepless adjustment mode, transparency can also be represented by levels, such as level 1, level 2, level 3, level 4, ..., level 9. Each level corresponds to a level of transparency.

[0068] The effective voltage value of the second electrical signal is determined based on any of the above methods or other implementation means, and the waveform of the second electrical signal is adjusted so that the transparency of the stacked component is consistent with the target transparency. Here, consistency can be understood as wirelessly approaching the target transparency.

[0069] like Figure 4 As shown, when the second electrical signal AC2 is a half-wave signal and the first electrical signal AC1 is a square wave signal of the same frequency, it can be adjusted... Figure 4 The effective value of the mid-wave signal changes the transparency of the stacked module. As the effective value of the second electrical signal AC2 increases, the total voltage synthesized from the first electrical signal AC1 and the second electrical signal AC2 decreases, resulting in lower transparency and a larger induced voltage on the second functional layer. Therefore, as... Figure 5 As shown, when the power level is inversely proportional to the transparency (i.e., the lower the power level, the higher the transparency and the lower the atomization), and vice versa, the higher the power level, the lower the transparency and the higher the atomization), the effective value of the induced voltage on the second functional layer is less at higher power levels than at lower power levels.

[0070] And such as Figure 5 As shown, at the same gear level (voltage / V AC represents the total voltage of the first and second electrical signals), compared to the conventional technology where both the first and second electrical signals are loaded with square wave signals (i.e., scenario 1), the control method provided in this application embodiment has a smaller effective voltage value on the second functional layer (scenario 1 - the value in the sense) compared to the effective voltage value in the conventional technology (scenario 2 - the value in the sense). For example, for gear 9, the effective voltage value of the sensed voltage on the second functional layer is reduced from 19V to 11V, which is an effective reduction.

[0071] In one embodiment, the control method further includes:

[0072] In the non-transparent mode, a third electrical signal is applied to the second conductive layer. The third electrical signal has the same frequency, the same magnitude, and the opposite direction to the first electrical signal.

[0073] A non-transparent mode can be understood as a mode where the user needs to frost the glass, reducing visibility by maintaining low transparency. For example, for a PDLC dimming layer, a non-transparent mode could refer to the mode when the liquid crystal is not deflected. In this mode, by applying a third electrical signal to the second conductive layer, the total voltage applied to the first functional layer is 0, together with the first electrical signal, making the stacked component opaque. The effective voltage sensed on the second functional layer is approximately the same as the effective voltage value of the third electrical signal.

[0074] Optionally, the first and third electrical signals can be square wave signals of the same frequency. In this case, the voltage waveform induced on the second functional layer is also approximately a square wave, and its effective voltage value is roughly the same as that of the third electrical signal. For example, when both the first electrical signal AC1 and the second electrical signal AC2 are square wave signals with an effective value of 26V, a sine wave with a total voltage of approximately 0 is formed. Figure 6 As shown, the voltage G induced on the second functional layer is as follows: Figure 6As shown, it is roughly a square wave signal with an effective value of 26V.

[0075] In one embodiment, the effective voltage value of the first electrical signal is 0-100V, for example, it can be 26V. This effective voltage value is suitable for the dimming requirements of most automotive multilayer components. However, it should be noted that the effective voltage values ​​of the first and second electrical signals are specifically determined according to the functional requirements of the multilayer component in which they are applied. This is only an example and does not limit the specific voltage values ​​of the first and second electrical signals in this application.

[0076] To better illustrate the implementation process of the control method provided in this application, a specific implementation method is described here. However, it should be understood that the example here is intended to help those skilled in the art understand the implementation of this solution, and is not intended to limit the scope of protection of this application.

[0077] In non-transparent mode, square wave signals with an effective value of 26V are applied to both the first and second conductive layers. The signals are of the same magnitude but opposite in direction, and the total voltage is 0. Alternatively, the first functional layer can be powered off so that the total voltage applied is 0. In this case, the stacked component is in an opaque state.

[0078] When a user requires a certain level of transparency in the glass, a square wave signal with an effective value of 26V is applied to the first conductive layer, and a half-wave signal with an effective value of 26V is applied to the second conductive layer. The transparency of the glass is adjusted by increasing or decreasing the effective value of the square wave signal according to the desired target transparency. Increasing the effective value voltage of the half-wave signal reduces the total voltage of the sine wave synthesized with the first electrical signal, resulting in lower transparency. The voltage induced on the second functional layer increases with the increase in the effective value voltage of the half-wave signal. Conversely, decreasing the effective value voltage of the half-wave signal increases the total voltage of the sine wave synthesized with the first electrical signal, resulting in higher transparency. The effective value of the voltage induced on the second functional layer decreases.

[0079] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0080] Based on the same inventive concept, this application also provides a control device for implementing the control method described above. The solution provided by this device is similar to the solution described in the above method; therefore, specific limitations in one or more control device embodiments provided below can be found in the limitations of the control method described above, and will not be repeated here.

[0081] This application provides a control device, such as... Figure 7 As shown, the device includes: a first voltage loading module 720 and a second voltage loading module 740.

[0082] The first voltage loading module 720 is used to load a first electrical signal onto the first conductive layer of the first functional layer in the stacked assembly. The second voltage loading module 740 is used to load a second electrical signal onto the second conductive layer of the first functional layer. The second electrical signal has the same frequency as the first electrical signal but is in the opposite direction. The second conductive layer is closer to the second functional layer of the stacked assembly than the first conductive layer, and the effective voltage value of the second electrical signal is less than the effective voltage value of the first electrical signal, so as to reduce the induced charge on the second functional layer.

[0083] Through the coordinated action of the first voltage loading module 720 and the second voltage loading module 740, the induced charge on the second functional layer can be effectively reduced, resulting in a smaller and more stable induced voltage on the second functional layer. (See [link]). Figure 4-5 As shown, the first electrical signal AC1 and the second electrical signal AC2 are as follows: Figure 4 When the waveform shown is applied, the effective voltage value of the second electrical signal is less than the effective voltage value of the first electrical signal, such as... Figure 5 As shown, the amplitude of the induced voltage on the second functional layer (Scenario 2 - Induction) is lower than the amplitude of the induced voltage under traditional square wave drive (Scenario 1 - Induction).

[0084] In one embodiment, the first electrical signal is a square wave signal, and the second electrical signal is a half wave signal or a sawtooth wave signal.

[0085] In one embodiment, the first functional layer further includes a dimming layer, and a first electrical signal and a second electrical signal are used to jointly drive the dimming layer.

[0086] In one embodiment, the control device further includes:

[0087] The transparency adjustment module is used to adjust the effective value of the voltage of the second electrical signal to match the target transparency in transparency mode, based on the target transparency.

[0088] In one embodiment, the control device further includes:

[0089] A non-transparent control module is used to load a third electrical signal onto the second conductive layer in non-transparent mode. The third electrical signal has the same magnitude as the first electrical signal but is in the opposite direction.

[0090] In one embodiment, the effective voltage value of the first electrical signal is 0-100V, for example, it can be 26V, depending on the voltage required to realize the function of the first functional layer.

[0091] Each module in the aforementioned control device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in the processor of the controller in hardware form or independent of it, or stored in the memory of the controller in software form, so that the processor can call and execute the operations corresponding to each module.

[0092] In one embodiment, a controller is provided, which may be an integrated circuit-type controller, i.e., a small-size controller, for integration into a stacked component, and its internal structure diagram may be as follows. Figure 8 As shown, the controller includes a processor, memory, input / output interfaces, a communication interface, and input devices. The processor, memory, and input / output interfaces are connected via a system bus, and the communication interface and input devices are also connected to the system bus via the input / output interfaces. The processor provides computational and control capabilities. The controller's memory includes non-volatile storage media and internal memory. The non-volatile storage media stores the operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs stored in the non-volatile storage media. The controller's input / output interfaces are used for exchanging information between the processor and external devices. The controller's communication interface is used for wired or wireless communication with external terminals; wireless communication can be achieved through Wi-Fi, mobile cellular networks, NFC (Near Field Communication), or other technologies. When the computer program is executed by the processor, it implements a control method.

[0093] Those skilled in the art will understand that Figure 8 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the controller to which the present application is applied. A specific controller may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0094] In one embodiment, a controller is provided, including a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the steps of the control method described above, at least achieving the purpose of reducing the induced voltage on the second functional layer of the stacked component. Furthermore, by executing other steps in the above method embodiments, the controller can also achieve other corresponding beneficial effects, which will not be elaborated here.

[0095] In one embodiment, a stacked component is provided, such as Figure 9 As shown, it includes: a transparent substrate (10, 13), a first functional layer and a second functional layer 60 disposed on the transparent substrate, and the controller described above;

[0096] The first functional layer includes a first conductive layer 42 and a second conductive layer 46 stacked together, wherein the second conductive layer 46 is closer to the second functional layer 60 than the first conductive layer 42.

[0097] The controller is electrically connected to the first conductive layer 42 and the second conductive layer 46, respectively.

[0098] The process of power supply control by the controller can be found in the above embodiments and will not be repeated here. The laminated assembly may also include other structures such as a substrate layer. Optionally, the transparent substrate may be, but is not limited to, a glass plate, a transparent polyimide (PI) plate, a transparent plastic plate, etc.

[0099] In one of the implementations, such as Figure 10 As shown, the transparent substrate includes a first substrate layer 10 and a second substrate layer 30 disposed opposite to each other, and the first substrate layer 10 and the second substrate layer 30 form a sandwich space; the first functional layer and the second functional layer 60 are both disposed in the sandwich space, and are directly or indirectly disposed on the first substrate layer 10 or the second substrate layer 30.

[0100] The first substrate layer 10 and the second substrate layer 30 can be bonded together by an adhesive layer 50. For example, an adhesive ring is coated around the edge of the first substrate layer 10 to bond the second substrate layer 30. The adhesive has a certain thickness, forming the aforementioned interlayer space. Of course, the connection between the first substrate layer 10 and the second substrate layer 30 can also be achieved through integral molding technology during glass manufacturing.

[0101] In one implementation, the controller 20 includes a power supply terminal D1, a ground terminal D2, a first output terminal D3, and a second output terminal D4; the ground terminal D2 is used to connect to a ground signal.

[0102] The controller 20 is used to receive the power supply voltage from the power supply terminal D1, and after converting the power supply voltage, it is applied to the first conductive layer 42 and the second conductive layer 46 through the first output terminal D3 and the second output terminal D4 respectively.

[0103] In one of the implementations, such as Figure 10 As shown in Figure 11, the second functional layer 60 is grounded. The charge distribution on the second functional layer 60 before and after grounding is as follows: Figure 11a and Figure 11bAs shown, the charge on the surface of the second functional layer 60 is significantly reduced under the grounding setting. Furthermore, waveform tests were performed on the second functional layer 60 and the second electrical signal AC2 before and after the grounding setting, as shown below. Figure 11c and Figure 11d The waveform diagram is shown below. Figure 11c As shown, before grounding, the waveform G of the second functional layer 60 is nearly identical to the waveform of the second electrical signal AC2, while referring to... Figure 11d After grounding, the voltage G on the second functional layer 60 is 0V. Both charge distribution and waveform test results show that grounding the second functional layer 60 results in an induced voltage amplitude of 0, preventing electric shock to users when they touch the second functional layer 60 on the surface of the stacked component, thus improving user experience and product safety.

[0104] The grounding of the second functional layer 60 can also be achieved by connecting the grounding terminal D1 of the controller 20, sharing a grounding point, and reducing the number of electrical solder joints in the multilayer module. On the one hand, this reduces costs; on the other hand, it reduces the area requirements for the non-transparent areas of the multilayer module. For example, when the transparent substrate is glass, electrical components are usually placed on the black edge of the glass. Reducing the number of solder joints such as grounding points helps to reduce the area of ​​the black edge of the glass, resulting in a larger light-receiving area in the multilayer module. Therefore, optionally, the wiring for grounding the second functional layer 60 can be placed on the black edge of the glass.

[0105] In one embodiment, the first functional layer further includes a dimming layer 44 disposed between the first conductive layer 42 and the second conductive layer 46.

[0106] This application also provides a vehicle, including: a body; and one or more of the above-described stacked components, the stacked components being correspondingly mounted on various mounting positions of the body.

[0107] The transparent substrate can be a glass plate, and the laminated assembly can include at least one of the following: windshield, rear windshield, side window glass, and sunroof glass. When the laminated assembly is installed at the sunroof location, it enables panoramic sunroof technology without sunshades, while also increasing heat insulation.

[0108] Optionally, multiple stacked components that are close together can share a single controller. In this case, the controller can be equipped with multiple sets of first and second output terminals to achieve independent control of each individual stacked component. For example, for the front and rear windows on the same side, controllers can be placed in the adjacent areas where they are close to each other and share a single controller.

[0109] Of course, a single controller can also correspond to a single stacked component. The specific choice depends on the installation conditions on the vehicle body, wiring space, and other factors.
