Description

Technical Field

[0001] This disclosure relates to the field of display technology, and more particularly to dimming glass, dimming systems and control methods for vehicles. Background Technology

[0002] Smart glass is a high-end functional glass with adjustable transparency and privacy protection. It switches between a scattering state (opaque) and a transmission state (transparent) through voltage control, achieving the dual requirements of transparency and privacy. Smart glass has a wide range of applications, including but not limited to architecture, transportation, and interior design. Existing smart glass frames are densely packed with various metal wires. To conceal these wires, most smart glass frames use black resin frames, which are neither aesthetically pleasing nor practical. Improving the dimming flexibility and enhancing the overall aesthetics of various types of smart glass is a topic of continuous research and development.

[0003] The information disclosed in this section is only for understanding the background of the inventive concept of this disclosure, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] One aspect of the embodiments of this disclosure provides a dimming glass for a vehicle, comprising:

[0006] First substrate;

[0007] A first dimming area and a second dimming area are located on the first substrate, wherein the orthographic projection of the second dimming area on the first substrate at least partially surrounds the orthographic projection of the first dimming area on the first substrate.

[0017] The second dimming component is configured such that the transmittance of the second dimming area decreases as the transmittance of the first dimming area decreases.

[0018] In some embodiments, the dimming glass is configured such that, in response to an electrical signal applied to at least one of the first dimming component and the second dimming component, the state of the dimming glass changes such that the dimming glass switches to a predetermined state, in which the dimming glass has a predetermined pattern, the predetermined pattern comprising a pattern displayed by at least a portion of a first dimming area and by at least a portion of a second dimming area;

[0019] At least one of the following attributes of the predetermined pattern is determined in response to user input:

[0024] In some embodiments, the predetermined pattern includes a dynamic pattern that changes at predetermined time intervals. In the dynamic pattern generated by the nth change, the transmittance of the first dimming area display pattern is the same as that of the second dimming area display pattern. Compared with the dynamic pattern generated by the i-th change, the transmittance of the first dimming area and the second dimming area display pattern changes synchronously in the dynamic pattern generated by the (i+1)th change, where i is a positive integer and n is a positive integer less than or equal to i.

[0091] It should be noted that, for clarity, the dimensions of layers, structures, or regions in the accompanying drawings used to describe embodiments of this disclosure may be enlarged or reduced; that is, these drawings are not drawn to actual scale. Detailed Implementation

[0092] The technical solutions of this disclosure will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this disclosure with reference to the accompanying drawings is intended to explain the overall inventive concept of this disclosure and should not be construed as a limitation thereof.

[0093] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details.

[0094] It should be understood that although the terms first, second, etc., may be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of the exemplary embodiments, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0095] It should be understood that when an element or layer is referred to as being "formed on" another element or layer, that element or layer may be formed directly or indirectly on the other element or layer. That is, for example, intermediate elements or intermediate layers may exist. Conversely, when an element or layer is referred to as being "directly formed on" another element or layer, there are no intermediate elements or intermediate layers. Other terms used to describe relationships between elements or layers (e.g., "between" and "directly between," "adjacent" and "directly adjacent," etc.) should be interpreted in a similar manner. Furthermore, the X-axis, Y-axis, and Z-axis are not limited to the three axes of a Cartesian coordinate system and can be interpreted in a broader sense. For example, the X-axis, Y-axis, and Z-axis may be perpendicular to each other or may represent different directions that are not perpendicular to each other. For the purposes of this disclosure, "at least one of X, Y, and Z" and "at least one selected from the group consisting of X, Y, and Z" can be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z such as XYZ, XY, XZ, and YZ.

[0096] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments. As used herein, the singular forms are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “including” are used herein, it indicates the presence of the stated features, integrals, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0097] It should be noted that in this article, the meaning of "pre-planned" includes: the object modified by "pre-planned" is not randomly generated, but generated in response to information such as control signals and user input. It should be understood that the object modified by "pre-planned" corresponds to information such as control signals and user input, and the correspondence is predetermined.

[0098] In related technologies, the frame of dimming glass is densely covered with various metal traces. In order to cover these metal traces, most dimming glass frames are made of black resin, which is neither aesthetically pleasing nor practical.

[0099] In response, embodiments of this disclosure provide a dimming glass for vehicles, a dimming system and a control method thereof, which uses a new dimming area to replace the black border. This new dimming area not only has the function of concealing the circuit, but can also dim along with the liquid crystal dimming area, thereby improving the overall aesthetics of the dimming glass and increasing the flexibility of dimming.

Figure 2AThe dimming glass according to some exemplary embodiments of this disclosure is in the transparent state along... Figure 1 The cross-sectional view taken from line AA' in the diagram. Figure 2B The dimming glass according to some exemplary embodiments of this disclosure is used in the dark state. Figure 1 The cross-sectional view taken from line AA' in the diagram.

[0101] Combined with reference Figure 1 , Figure 2A and Figure 2B The dimming glass 10 includes: a first substrate 11 and a second substrate 21 disposed opposite to each other; a first electrode 12 disposed on the first substrate 11; a second electrode 22 disposed on the second substrate 21; and a first dimming component 30 and a second dimming component 40 sandwiched between the first substrate 11 and the second substrate 21.

[0102] For example, the first substrate 11 and the second substrate 21 can each be a transparent glass substrate, which allows the dimming glass 10 to have good light transmittance in the transparent state. For example, the dimming glass 10 can be applied in fields such as architecture, transportation, and interior design to achieve switching between a transparent state and a non-transparent state (e.g., a dark state or a foggy state). For example, the dimming glass 10 includes various types such as polymer dispersed liquid crystal (PDLC) dimming glass 10 and dye liquid crystal dimming glass 10.

[0103] For example, the first electrode 12 and the second electrode 22 can be transparent electrodes, for example, they can be made of transparent conductive materials such as indium tin oxide (ITO) or indium zinc oxide (IZO).

[0104] In some embodiments of this disclosure, the first dimming component 30 includes a first electrode 12, a second electrode 22, and a liquid crystal layer 31 sandwiched between the first electrode 12 and the second electrode 22, such as a dye liquid crystal layer. Specifically, the dye liquid crystal layer may include liquid crystal molecules and colorimetric dye molecules mixed with the liquid crystal molecules. For example, the colorimetric dye molecules may be dichroic dye molecules.

[0105] In some embodiments of this disclosure, the second dimming component 40 includes a first electrode 12, a second electrode 22, and a frame material 41 sandwiched between the first electrode 12 and the second electrode 22. The frame material 41 is doped with an electrochromic unit 42. The frame material 41 is located between the first substrate 11 and the second substrate 21 and surrounds the liquid crystal layer 31. The frame material 41 can reduce the risk of moisture in the air entering the dimming glass 10 and extend the service life of the dimming glass 10. When an electric field is applied to the electrochromic unit 42, the electrochromic unit 42 undergoes a redox reaction, producing a color change caused by a change in valence state, thereby achieving the dimming function.

[0106] Reference Figure 1 The frame material 41 defines a first dimming area 301 and a second dimming area 401 on the dimming glass 10. The orthographic projection of the second dimming area 401 on the first substrate 11 at least partially surrounds the orthographic projection of the first dimming area 301 on the first substrate 11. The dimming glass 10 includes a first dimming component 30 located in the first dimming area 301 and a second dimming component 40 located in the second dimming area 401. The first dimming component 30 is configured to adjust the transmittance of the first dimming area 301, and the second dimming component 40 is configured to adjust the transmittance of the second dimming area 401.

[0107] Reference Figure 2A For example, in the first dimming component 30, the liquid crystal layer 31 includes liquid crystal molecules and color dye molecules, and the electrochromic unit 42 includes a cathode electrochromic material. When no driving voltage is applied to the first electrode 12 and the second electrode 22, no electric field is generated between the first electrode 12 and the second electrode 22. The liquid crystal molecules and color dye molecules in the first dimming component 30 are vertically oriented and do not absorb light, making the first dimming area 301 transparent. At the same time, the electrochromic unit 42 in the second dimming component 40 is colorless, making the second dimming area 401 transparent. The first dimming area 301 and the second dimming area 401 have the same or similar colors, giving the dimming glass 10 an overall aesthetic appeal.

[0108] Reference Figure 2B When a predetermined driving voltage is applied to the first electrode 12 and the second electrode 22, an electric field is generated between the first electrode 12 and the second electrode 22. This causes the liquid crystal molecules and color dye molecules in the liquid crystal layer 31 of the first dimming component 30 to deflect. Under the influence of the electric field, the liquid crystal molecules align horizontally, inducing the color dye molecules to align horizontally as well, thus absorbing light and making the first dimming area 301 opaque (i.e., dark). During the deflection of the liquid crystal molecules, the color dye molecules rotate in the same phase as the liquid crystal molecules under the influence of intermolecular forces. Different rotation angles of the color dye molecules result in different light absorption rates and different light-blocking effects, thus giving the first dimming area 301 different transmittance. Simultaneously, the electrochromic unit 42 in the second dimming component 40 undergoes a redox reaction under the influence of the electric field, producing a color change caused by a change in valence state, such as appearing blue, making the second dimming area 401 partially transparent. By combining multiple electrochromic materials, a richer range of color variations can be provided, allowing the second dimming area 401 to have different light transmittances. The second dimming area 401 can be dimmed in conjunction with the first dimming area 301, improving the flexibility of dimming.

[0109] In this way, by controlling the driving voltage applied to both sides of the first dimming region 301 and the second dimming region 401, the deflection state of the liquid crystal molecules in the liquid crystal layer 31 and the valence state of the electrochromic unit 42 can be controlled, thereby controlling the transmittance of the dimming glass 10 (i.e., the gradual change between the transparent and dark states). The dimming glass 10 includes a normally white mode and a normally black mode. The normally white mode is in a transparent state (i.e., the transmittance is 100% or approximately 100%), and the normally black mode is in a dark state (i.e., the transmittance is 0% or in a lower range).

[0110] Reference Figures 2A-2B The dimming glass 10 may also include spacers 32 for support. Optionally, the spacers 32 may be spherical, columnar, or other shaped spacers 32, and may be made of transparent or opaque materials.

[0111] Reference Figures 2A-2B The diagram only shows a single first substrate 11, a single second substrate 21, a single first electrode 12, a single second electrode 22, a single first dimming component 30, and a single second dimming component 40, referred to herein as a single-cell structure. In some embodiments of this disclosure, at least two single-cell structures can be stacked to form a double-cell structure or more cell structures. In multiple cell structures, the long axes of the liquid crystal molecules in the liquid crystal layers 31 of at least two cell structures are perpendicular or substantially perpendicular to each other.

[0112] In the above embodiments, dye liquid crystal was used as an example to illustrate the dimming glass 10 provided in the embodiments of this disclosure. It should be understood that the dimming glass 10 provided in the embodiments of this disclosure may also include other types of liquid crystal, including but not limited to polymer dispersed liquid crystal (PDLC).

[0113] Figure 3 and Figure 4 These are embodiments according to this disclosure. Figure 2A and Figure 2B The diagram shows a plan view of the first dimming substrate 1 and the second dimming substrate 2 of the dimming glass 10. The first dimming substrate 1 includes a first substrate 11 and a first electrode 12, and the second dimming substrate 2 includes a second substrate 21 and a second electrode 22.

[0114] Combined with reference Figure 2A , Figure 2B and Figure 3 The first dimming substrate 1 includes a first electrode 12 comprising a plurality of sub-electrodes 121, which are arranged at intervals on the first substrate 11.

[0115] In some embodiments of this disclosure, at least one of the sub-electrodes 121 is a strip electrode. The orthogonal projection of the strip electrode on the first substrate 11 includes a first side extending along a first direction and a second side extending along a second direction. The lengths of the first side and the second side are not equal. The first direction is perpendicular to the second direction.

[0116] Combined with reference Figure 3 At least one of the sub-electrodes 121 is a strip electrode. The orthographic projection of the strip electrode on the first substrate 11 includes a first side extending along a first direction (such as the X-axis direction, the same below) and a second side extending along a second direction (such as the Y-axis direction, the same below). The first direction is perpendicular to the second direction. The orthographic projection of the first electrode 12 on the first substrate 11 is formed as a plurality of spaced strip shapes. It should be understood that each sub-electrode 121 is a transparent sub-electrode 121. For example, each sub-electrode 121 is made of a transparent conductive material such as ITO.

[0117] Reference Figure 3 The dimming glass 10 may further include a plurality of traces 15 disposed on the first substrate 11. Exemplarily, the plurality of traces 15 may correspond one-to-one with a plurality of sub-electrodes 121. For example, each trace may be a conductive trace made of a conductive material.

[0118] Reference Figure 3 The dimming glass 10 may also include, for example, a driving circuit 16 for an IC, which provides electrical signals. Specifically, multiple traces 15 can electrically connect corresponding sub-electrodes 121 to the driving circuit 16 for example, the IC, so that the control signals provided by the driving circuit 16 can be supplied to multiple sub-electrodes 121 respectively.

[0119] The second dimming substrate 2 includes a second electrode 22, which can be a planar electrode. That is, the orthogonal projection of the second electrode 22 onto the second substrate 21 forms a continuously distributed planar pattern shape. For example, in Figure 4 In one embodiment, the second electrode 22 is projected onto the second substrate 21 in the form of a complete rectangle.

[0120] For example, the orthographic projection of the first electrode 12 on the first substrate 11 falls within the orthographic projection of the second electrode 22 on the first substrate 11.

[0121] It should be understood that the second electrode 22 can also be electrically connected to, for example, the driving circuit 16 of an IC through a conductive structure (such as a trace), so that the control signal provided by the driving circuit 16 can be supplied to the second electrode 22.

[0122] In some embodiments of this disclosure, the dimming glass 10 is configured such that, in response to an electrical signal applied to at least one of the first electrode 12 and the second electrode 22, the state of the dimming glass 10 changes, causing the dimming glass 10 to switch to a predetermined state in which the dimming glass 10 has a predetermined pattern, the predetermined pattern comprising a pattern displayed by at least a portion of the first dimming area 301 and by at least a portion of the second dimming area 401; at least one of the following properties of the predetermined pattern is determined in response to user input: the shape of the predetermined pattern, the transmittance of the predetermined pattern, and the dynamic properties of the predetermined pattern.

[0123] For example, the electrical signal can be a voltage signal. The voltage signal includes a predetermined driving voltage applied, which is transmitted to the first electrode 12 and / or the second electrode 22 during the operation of the dimming glass 10, controlling the deflection state of the liquid crystal molecules in the liquid crystal layer 31 and the valence state of the electrochromic unit 42, so as to control the light transmittance of the first dimming area 301 and the second dimming area 401.

[0124] Reference Figure 3 An electrical signal can be applied by the driving circuit 16 to the first electrode 12 and / or the second electrode 22 via the trace 15. For each sub-electrode 121 in the first electrode 12, the electrical signal transmitted by one trace and at least one of the other traces may be the same or different. In the dimming glass 10 provided in the embodiments of this disclosure, the driving circuit 16 can supply an electrical signal to one or more of the plurality of sub-electrodes 121 and to the second electrode 22 to generate an electric field between one or more of the sub-electrodes and the second electrode 22, thereby changing the transmittance of the corresponding area of ​​one or more of the sub-electrodes.

[0125] In this way, diverse dimming effects can be achieved. For example, the transmittance of each sub-electrode region can be adjusted independently. When it is necessary to adjust the transmittance of a certain region of the dimming glass 10, an electrical signal can be applied to the sub-electrode and the second electrode 22 of that region. For example, the driving voltage of the sub-electrode of that region is different from that of other sub-electrodes, and a corresponding electric field is generated in the region opposite to the sub-electrode and the second electrode 22, so as to achieve independent control of the transmittance of that region.

[0126] Reference Figures 2A-2B The change in the state of the dimming glass 10 can refer to the deflection of liquid crystal molecules and color dye molecules in the liquid crystal layer 31 and the redox reaction of the electrochromic unit 42. The liquid crystal molecules are horizontally aligned under the action of the electric field, which induces the color dye molecules to be horizontally aligned, thereby absorbing light. The electrochromic unit 42 produces a color change caused by the change of valence state, so that at least a part of the dimming glass 10 has the same or different light transmittance compared with other at least a part of the region.

[0127] In some embodiments, among the liquid crystal layers 31 and electrochromic units 42 corresponding to the plurality of sub-electrodes, at least two sub-electrodes have different colors of chromatic dye molecules in their dye liquid crystal layers 31 and / or different colors of their electrochromic units 42. For example, the chromatic dye molecule corresponding to one sub-electrode may be green, while the chromatic dye molecule corresponding to any other sub-electrode may be purple; and / or the electrochromic unit 42 corresponding to one sub-electrode may be blue, while the electrochromic unit 42 corresponding to any other sub-electrode may be green, thereby providing a diverse range of dimming functions.

[0128] In some embodiments of this disclosure, the first dimming component 30 is configured to set a first initial transmittance for the first dimming area 301; and the second dimming component 40 is configured to set a second initial transmittance for the second dimming area 401.

[0129] For example, the initial state of the dimming glass 10 has high transparency, and the initial transmittance of the first dimming area 301 and the second dimming area 401 can be the same or different. For example, the first initial transmittance of the first dimming area 301 is 95%, and the second initial transmittance of the second dimming area 401 is 100%; the dimming glass 10 is generally in a transparent state.

[0130] Figure 5 This is a schematic diagram of setting a first initial transmittance for a first dimming zone in a dimming glass according to some exemplary embodiments of the present disclosure.

[0131] Reference Figure 5 The first initial light transmittance is greater than the second initial light transmittance. For example, the first initial light transmittance of the first dimming zone 301 is 100%, and the second initial light transmittance of the second dimming zone 401 is 95%. The dimming glass 10 presents a picture frame pattern, and the light transmittance of the first dimming zone 301 and the second dimming zone 401 are close, making the dimming glass 10 overall harmonious and aesthetically pleasing.

[0132] Figures 6A to 6C This is a schematic diagram showing the synchronous change of light transmittance between a first dimming zone and a second dimming zone of a dimming glass according to some exemplary embodiments of the present disclosure.

[0133] In some embodiments of this disclosure, the first dimming component 30 and the second dimming component 40 are configured such that the transmittance of the first dimming area 301 changes synchronously with the transmittance of the second dimming area 401.

[0134] The first dimming component 30 and the second dimming component 40 at least partially share the first electrode 12 and the second electrode 22. The control signal provided by the driving circuit 16 can be supplied to the first electrode 12 and the second electrode 22 respectively to realize synchronous control of the transmittance of the first dimming area 301 and the second dimming area 401.

[0135] Reference Figure 6A By applying a predetermined driving voltage to the first electrode 12 and the second electrode 22, the color of the first dimming area 301 deepens, and simultaneously the color of the second dimming area 401 deepens. For example, the transmittance of the first dimming area 301 decreases from 100% to 90%, while the transmittance of the second dimming area 401 decreases from 100% to 80%. (Refer to...) Figure 6B By reducing the voltage applied to the first electrode 12 and the second electrode 22, the color of the first dimming area 301 becomes lighter, and simultaneously the color of the second dimming area 401 also becomes lighter. That is, the transmittance of the first dimming area 301 increases from 90% to 100%, and the transmittance of the second dimming area 401 increases from 80% to 100%. This configuration allows the transmittance of the first dimming area 301 and the second dimming area 401 to change synchronously, facilitating user operation on the dimming glass 10. For example, when a user operates on the second dimming area 401 and adjusts its transmittance, the transmittance of the first dimming area 301 changes accordingly, allowing for easy observation and preventing visual interference from arm movements.

[0136] In some embodiments of this disclosure, the second dimming component 40 is configured such that the transmittance of the second dimming area 401 can change with the transmittance of the first dimming area 301.

[0137] For example, the second dimming component 40 is configured such that the transmittance of the second dimming area 401 increases as the transmittance of the first dimming area 301 increases; and / or, the second dimming component is configured such that the transmittance of the second dimming area 401 decreases as the transmittance of the first dimming area 301 decreases.

[0138] In some embodiments of this disclosure, the adjustable range of the light transmittance of the dimming glass is divided into several levels, each corresponding to a fixed light transmittance. The difference in light transmittance between the levels is discernible to the human eye. In response to a specific ambient light intensity outside the vehicle, the light transmittance of the first dimming zone 301 differs from that of the second dimming zone 401 by at least one level, and / or the light transmittance of the first dimming zone 301 and the second dimming zone 401 under a specific ambient light intensity remains consistent with their light transmittance under a non-specific ambient light intensity. Here, a specific ambient light intensity refers to the relatively strongest or weakest ambient light intensity (e.g., a very dark tunnel / parking lot, a very bright strong light environment), and a non-specific ambient light intensity refers to a relatively moderate ambient light intensity. Under the strongest or weakest ambient light intensity, the transmittance of the first dimming area 301 and the second dimming area 401 differs by at least one level, making it convenient for users to observe the difference in transmittance between the first dimming area 301 and the second dimming area 401, thereby accurately determining the area (boundary) of touch control.

[0139] In some embodiments of this disclosure, in response to non-specific ambient light intensity outside the vehicle, the transmittance of the first dimming area 301 differs from that of the second dimming area 401 by at least one level, and / or the transmittance of the first dimming area 301 and the second dimming area 401 under non-specific ambient light intensity remains consistent with the transmittance under specific ambient light intensity. Under relatively moderate ambient light intensity, the transmittance of the first dimming area 301 and the second dimming area 401 differs by at least one level, allowing users to easily observe the transmittance difference between the first dimming area 301 and the second dimming area 401 in normal environments, maintaining a consistent visual experience with specific ambient light intensity.

[0140] In some embodiments of this disclosure, the dimming glass 10 has an initial state before switching to a predetermined state. In the initial state, the dimming glass 10 has an initial pattern in which the transmittance of at least a portion of the second dimming area display pattern is different from the transmittance of at least a portion of the first dimming area display pattern; and / or the transmittance of at least a portion of the second dimming area display pattern in the predetermined pattern is the same as the transmittance of at least a portion of the first dimming area display pattern.

[0141] Reference Figure 6C , Figure 6C In the middle (a), the initial pattern is shown. The first initial light transmittance of the first dimming zone 301 is 100%, and the second initial light transmittance of the second dimming zone 401 is 95%. The dimming glass 10 presents a picture frame pattern. Figure 6C In the middle (b), the predetermined pattern is shown. The first initial light transmittance of the first dimming zone 301 is 80%, and the second initial light transmittance of the second dimming zone 401 is 80%. The dimming glass 10 presents a uniform light transmittance pattern on the whole surface, which has an overall aesthetic appeal.

[0142] Figures 7A-7BThis is a schematic diagram of a dynamic pattern of a dimming glass that varies with a certain transmittance difference according to some exemplary embodiments of the present disclosure.

[0143] In some embodiments of this disclosure, the predetermined pattern includes a dynamic pattern that changes at predetermined time intervals. The dynamic pattern changes with a certain transmittance difference. Compared with the dynamic pattern generated in the i+1th change, the transmittance of the pattern displayed in the first dimming area 301 is increased or decreased, and the transmittance of the pattern displayed in the second dimming area 401 is increased or decreased, where i is a positive integer.

The transmittance of the pattern displayed in the first dimming area 301 gradually decreases in 10% transmittance differences, and the transmittance of the pattern displayed in the second dimming area 401 gradually decreases in 10% transmittance differences. It can be understood that the transmittance difference can be any value between 0 and 100%, and the number of dynamic patterns can also be other values.

[0147] In some embodiments of this disclosure, the predetermined pattern includes a dynamic pattern that changes at predetermined time intervals. In the dynamic pattern generated by the nth change, the transmittance of the first dimming area display pattern is the same as that of the second dimming area display pattern. Compared with the dynamic pattern generated by the ith change, the transmittance of the first dimming area 301 and the second dimming area 401 display patterns changes synchronously in the (i+1)th change, where i is a positive integer and n is a positive integer less than or equal to i.

[0148] Reference Figure 8A The predetermined pattern includes dynamic patterns (a) to (f), and the predetermined pattern changes sequentially from dynamic pattern (a) to dynamic pattern (f). In dynamic pattern (a), the transmittance of the first dimming area 301 is 100%, and the transmittance of the second dimming area 401 is 90%; in dynamic pattern (b), the transmittance of the first dimming area 301 is 90%, and the transmittance of the second dimming area 401 is 80%; in dynamic pattern (c), the transmittance of the first dimming area 301 is 80%, and the transmittance of the second dimming area 401 is 80%; in dynamic pattern (d), the transmittance of the first dimming area 301 is 70%, and the transmittance of the second dimming area 401 is 70%; in dynamic pattern (e), the transmittance of the first dimming area 301 is 60%, and the transmittance of the second dimming area 401 is 60%; in dynamic pattern (f), the transmittance of the first dimming area 301 is 50%, and the transmittance of the second dimming area 401 is 50%. In the dynamic pattern (c) generated by the second change, the transmittance of the pattern displayed in the first dimming area 301 is the same as that of the pattern displayed in the second dimming area 401. In the dynamic patterns (d) to (f) generated by the third to fifth changes, the transmittance of the pattern displayed in the first dimming area 301 changes synchronously with that of the pattern displayed in the second dimming area 401 and remains the same.

[0149] Reference Figure 8BThe predetermined pattern includes dynamic patterns (g) to (l), and the predetermined pattern changes sequentially from dynamic pattern (g) to dynamic pattern (l). In dynamic pattern (g), the transmittance of the first dimming area 301 is 60%, and the transmittance of the second dimming area 401 is 50%; in dynamic pattern (h), the transmittance of the first dimming area 301 is 60%, and the transmittance of the second dimming area 401 is 60%; in dynamic pattern (i), the transmittance of the first dimming area 301 is 70%, and the transmittance of the second dimming area 401 is 70%; in dynamic pattern (j), the transmittance of the first dimming area 301 is 80%, and the transmittance of the second dimming area 401 is 80%; in dynamic pattern (k), the transmittance of the first dimming area 301 is 90%, and the transmittance of the second dimming area 401 is 90%; in dynamic pattern (l), the transmittance of the first dimming area 301 is 100%, and the transmittance of the second dimming area 401 is 100%. In the dynamic pattern (h) generated by the first change, the transmittance of the pattern displayed in the first dimming area 301 is the same as that of the pattern displayed in the second dimming area 401. In the dynamic patterns (i) to (l) generated by the second to fifth changes, the transmittance of the pattern displayed in the first dimming area 301 changes synchronously with that of the pattern displayed in the second dimming area 401 and remains the same.

[0150] In some embodiments of this disclosure, the predetermined pattern includes k partitions, which are arranged side-by-side along a first direction or a second direction. Each partition includes at least a portion of a first dimming area 301 and at least a portion of a second dimming area 401, where k is a positive integer greater than or equal to 2. At least one of the first electrode 12 and the second electrode 22 includes Q sub-electrodes 121; in a predetermined state, the orthographic projection of k of the Q sub-electrodes 121 on the first substrate 11 falls within the orthographic projection of the predetermined pattern on the first substrate 11.

[0151] exist Figure 3 The diagram illustrates, exemplarily, the structure and arrangement of the Q sub-electrodes 121 comprising the first electrode 12. Figure 3 In the exemplary embodiment shown, the first electrode 12 includes four sub-electrodes 121, i.e., Q = 4; Figure 3 The number of sub-electrodes 121 shown is merely exemplary and should not be construed as a limitation on the number of sub-electrodes 121 included in the first electrode 12 or the second electrode 22. In other embodiments, the number of sub-electrodes 121 included in the first electrode 12 or the second electrode 22 may be the same as... Figure 3 The number of sub-electrodes shown is different.

[0152] It should be noted that the k partitions are determined based on user input. The k partitions correspond one-to-one with the k sub-electrodes. Therefore, the predetermined pattern formed by the k partitions corresponds to the area formed by the k sub-electrodes. That is, the orthographic projection of the k sub-electrodes on the first substrate 11 falls within the orthographic projection of the predetermined pattern on the first substrate 11.

[0153] Figures 9A-9B This is a schematic diagram of the dynamic pattern changes of a dimming glass partition according to some exemplary embodiments of the present disclosure.

[0154] In some embodiments of this disclosure, in response to an electrical signal applied to at least one of the first electrode 12 and the second electrode 22, the transmittance of at least one of the k partitions of the predetermined pattern is not equal to that of the initial pattern.

[0155] Reference Figure 9A The first dimming zone 301 and the second dimming zone 401 include zones ① to ④. Figure 9A In the middle (a), the initial pattern is shown, and the initial transmittance of each of the sections ① to ④ is 100%. Figure 9A In diagram (b), a predetermined pattern is shown, where the light transmittance of sections ① and ② becomes 90%, while the light transmittance of sections ③ and ④ remains unchanged. It can be understood that the light transmittance of each section can be arbitrarily changed according to requirements.

[0156] In some embodiments of this disclosure, in a predetermined state, each partition in the predetermined pattern varies with a predetermined transmittance difference until the transmittance of the partition reaches a predetermined fixed value.

[0157] Reference Figure 9B The predetermined pattern includes dynamic patterns (a) to (c), and the predetermined pattern changes sequentially from dynamic pattern (a) to dynamic pattern (c). The first dimming area 301 and the second dimming area 401 include partitions ① to ④. In dynamic pattern (a), the transmittance of partitions ① to ④ is 100%; in dynamic pattern (b), the transmittance of partition ① is 80%, the transmittance of partition ② is 90%, the transmittance of partition ③ is 95%, and the transmittance of partition ④ is 100%; in dynamic pattern (c), the transmittance of partition ① is 60%, the transmittance of partition ② is 80%, the transmittance of partition ③ is 95%, and the transmittance of partition ④ is 100%. The transmittance difference in zone ① is 20%, and the predetermined fixed value is 60%; the transmittance difference in zone ② is 10%, and the predetermined fixed value is 80%; the transmittance difference in zone ③ is 5%, and the predetermined fixed value is 95%. After the first change to the predetermined fixed value, the transmittance no longer changes; the transmittance of zone ④ is predetermined to be 100%, and remains unchanged.

[0158] Figures 10A to 10CThis is a schematic diagram of a dynamic pattern change of a dimming glass according to some exemplary embodiments of the present disclosure, with the pattern changing at predetermined partition intervals.

[0159] In some embodiments of this disclosure, the predetermined pattern includes a dynamic pattern that varies at a predetermined partition interval, wherein the predetermined partition interval is k1 partitions, and k1 is a positive integer less than k; in a predetermined state, the predetermined pattern gradually increases in spatial units of k1 partitions.

[0160] Reference Figure 10A The predetermined pattern includes dynamic patterns (a) to (d), and the predetermined pattern changes sequentially from dynamic pattern (a) to dynamic pattern (d). The first dimming zone 301 and the second dimming zone 401 include partitions ① to ④. The predetermined pattern gradually increases in size with one partition as the spatial unit, that is, the partition interval is 1, i.e., k = 4, k1 = 1.

[0161] Reference Figure 10B The predetermined pattern includes dynamic patterns (e) to (g), and the predetermined pattern changes sequentially from dynamic pattern (e) to dynamic pattern (g). The first dimming zone 301 and the second dimming zone 401 include partitions ① to ⑥. The predetermined pattern gradually increases in size with 3 partitions as spatial units, that is, the partition interval is 3, i.e., k = 6, k1 = 3.

[0162] It is understandable that, in the predetermined state, the predetermined pattern can also gradually decrease in size, using k1 partitions as spatial units. (Refer to...) Figure 10C The predetermined pattern includes dynamic patterns (h) to (j), and the predetermined pattern changes sequentially from dynamic pattern (h) to dynamic pattern (j). The first dimming zone 301 and the second dimming zone 401 include partitions ① to ⑥. The predetermined pattern gradually decreases in size with two partitions as the spatial unit, that is, the partition interval is 2, i.e., k = 6, k1 = 2.

[0163] It should be noted that, in Figures 10A to 10C In the exemplary embodiment shown, k1 = 1, k1 = 2 or k1 = 3. In other embodiments of this disclosure, k1 can take other values. For example, k1 can be equal to 4, 5, 6 or a larger number. Depending on the user's actual needs for the partition interval, k1 can take any positive integer less than k.

[0164] Figures 11A-11B This is a schematic diagram of a dynamic pattern change of a dimming glass according to some exemplary embodiments of the present disclosure, where the pattern changes with a predetermined rate of light transmission variation.

[0165] In some embodiments of this disclosure, the predetermined pattern includes a dynamic pattern that varies at predetermined partition intervals. In a predetermined state, at least one partition in the predetermined pattern varies with a predetermined rate of light transmittance until the light transmittance of the partition reaches a predetermined fixed value.

[0166] Reference Figure 11A The predetermined pattern includes dynamic patterns (a) to (d), and the predetermined pattern changes sequentially from dynamic pattern (a) to dynamic pattern (d). The first dimming zone 301 and the second dimming zone 401 include partitions ① to ④. The transmittance of partition ① is 100%, 90%, 70%, and 40% respectively from dynamic patterns (a) to (d). The transmittance of the predetermined pattern decreases sequentially by 10%, 20%, and 30%, that is, it changes at a transmittance change rate of 10%. The transmittance of this predetermined pattern can change rapidly to reach a predetermined fixed value, which is suitable for scenarios requiring rapid dimming.

[0167] In some embodiments of this disclosure, in a predetermined state, the dynamic pattern changes sequentially from the first partition to the kth partition; the first partition changes with a predetermined rate of change of light transmittance to reach a predetermined fixed value, and the light transmittance from the second partition to the kth partition changes directly to the fixed value.

[0168] Reference Figure 11B The predetermined pattern includes dynamic patterns (e) to (k), and the predetermined pattern changes sequentially from dynamic pattern (e) to dynamic pattern (k). The first dimming zone 301 and the second dimming zone 401 include partitions ① to ④. The transmittance of partition ① changes from 100%, 90%, 70%, and 40% respectively from dynamic patterns (a) to (d), reaching a predetermined fixed value with a transmittance change rate of 10%. The transmittance of partitions ② to ④ jumps directly from 100% to 40% sequentially. The transmittance of this predetermined pattern can change rapidly as a whole, making it suitable for scenes requiring rapid, large-area dimming.

[0169] In embodiments of this disclosure, the dynamic attributes of the predetermined pattern include at least one of the following: direction of dynamic change, partition interval, change period, and control interval. The direction of dynamic change can be gradually darkening from top to bottom, gradually darkening from left to right, gradually darkening from the center to the left and right, gradually darkening from the center to the top and bottom, or gradually whitening from top to bottom, gradually whitening from left to right, gradually whitening from the center to the left and right, or gradually whitening from the center to the top and bottom. The partition interval represents the control interval of each partition. The change period can be a single cycle, a finite number of cycles, or an infinite number of cycles. When the change period is a finite number of cycles or an infinite number of cycles, the change period needs to be set.

[0170] In embodiments of this disclosure, it is not intended to limit all states of the dimming glass 10 to... Figures 6A to 11B The content shown, in other words, except Figures 6A to 6C , Figures 7A-7B , Figures 8A-8B , Figures 9A-9B , Figures 10A to 10C and Figures 11A-11B In addition, the dimming glass 10 can have one or more other states.

[0171] Figures 12A-12C This is a schematic diagram of zoned control of a dimming glass according to some embodiments of the present disclosure. Figure 12A The first dimming zone 301 and the second dimming zone 401 are divided into two zones as a whole. Figures 12B-12C The second dimming zone 401 is divided into zones.

[0172] In order to achieve Figures 9A-9B , Figures 10A to 10C and Figures 11A-11B The effect of the zoned control shown is that an interactive component 50 is provided in the second dimming zone 401 of the dimming glass 10. The interactive component 50 is used to control the light transmittance of at least one of the first dimming zone 301 and the second dimming zone 401.

[0173] In some embodiments of this disclosure, the dimming glass further includes a plurality of interactive components 50, which are respectively disposed on one side of a plurality of partitions; the interactive components 50 are configured to generate control signals in response to user operations on the interactive components 50, the control signals being used to control the light transmittance of the partitions.

[0174] For example, the dimming glass 10 includes multiple zones, such as zones ① to ④, each zone being controlled by an independent interactive component 50. That is, each zone can independently control its light transmittance, dynamic properties, etc. It can be understood that the light transmittance and dynamic properties of zone ①, zone ②, zone ③, or zone ④ can all be independently controlled.

[0175] For example, this operation may include clicking, long pressing, swiping, or swiping after long pressing. Of course, the above operations are not limited to the examples listed. Changes in the user's interaction position with the interactive component 50 cause changes in the transmittance of the corresponding partition, for example, referring to... Figure 12A When a user clicks on interactive component 50, the component detects a decrease in light intensity, and if the light intensity falls below a preset threshold, the component generates an output signal to control the light transmittance of that zone to decrease. If the user clicks on the interactive components 50 for zones ① and ②, the light transmittance of zones ① and ② decreases. Changes in the duration of the user's interaction with the interactive component 50 cause changes in the light transmittance of the corresponding zone. For example, if the user long-presses the interactive component 50 for zone ①, zone ① changes its light transmittance at a predetermined rate of change to reach a predetermined fixed value, resulting in rapid dimming. Changes in the pressure applied by the user to the interactive component 50 also cause changes in the light transmittance of the corresponding zone. For example, if the user applies different pressures to the interactive component 50 for zone ①, zone ① changes its light transmittance at a predetermined rate of change to reach a predetermined fixed value, resulting in rapid dimming.

[0176] In some embodiments of this disclosure, the dimming glass is configured to: determine the direction of change of the dynamic pattern in response to an operation performed by a user on the dimming glass; and in a predetermined state, the dynamic pattern changes along the direction of change at predetermined partition intervals.

[0177] Reference Figure 12B The change in the user's interaction position with the interactive component 50 causes a change in the light transmittance of the corresponding partition. For example, when the user slides the interactive component 50 from top to bottom, the light transmittance of each partition of the first dimming zone 301 decreases by one level from top to bottom, and the light transmittance of each partition of the second dimming zone 401 decreases by one level from top to bottom, for example, the light transmittance decreases by 20%.

[0178] In some embodiments of this disclosure, the dimming glass 10 is configured such that, in response to an operation performed by a user on the dimming glass 10, the transmittance of at least one zone in a predetermined pattern changes with the duration of the operation.

[0179] Reference Figure 12C In (g) to (i), the change in the duration of user interaction with the interactive component 50 causes a change in the transmittance of the corresponding partition. For example, when the user touches the interactive component 50 in partition ①, the transmittance gradually increases or decreases as the interaction duration increases. When the user stops operating, the transmittance remains at the current transmittance value or the current level. For example, when the user operates on the interactive component with a single finger, the transmittance gradually increases; when the operation is with two fingers, the transmittance gradually decreases; or when the user operates on the interactive component with a single finger, the transmittance gradually decreases; when the operation is with two fingers, the transmittance gradually increases.

[0180] It should be noted that the transmittance of the dimming glass 10 has either a linear or non-linear relationship with voltage. The voltage changes in response to the user's operating time. For different types of transmittance-voltage relationships, the corresponding voltage for different transmittance levels or adjustment settings varies, therefore the change in transmittance caused by voltage changes also differs.

[0181] Reference Figure 12C (g)~(j) The changes in the time and position of the user's interaction with the interactive component 50 cause the transmittance of the corresponding partition to change. For example, when the user touches the interactive component 50 in partition ①, the uppermost partition of the first dimming zone 301 and the second dimming zone 401 (e.g., partition ①) changes with a predetermined transmittance change rate to reach a predetermined fixed value. Then, when the user touches the interactive component 50 in other partitions (e.g., partitions ②~④), the transmittance of the remaining partitions of the first dimming zone 301 and the second dimming zone 401 (e.g., partitions ②~④) jumps directly to the fixed value in sequence.

[0182] For example, the interactive component 50 includes a photoelectric component, which includes a transmitter, a receiver, and a detection circuit. The transmitter emits a light beam towards the target, the emitted light beam originating from a light-emitting diode or a laser diode. The receiver includes a photodiode or phototransistor. Optical elements such as lenses and apertures are arranged in the optical path before the receiver. The receiver converts the received light intensity changes into an electrical signal, which typically undergoes signal processing steps such as amplification and filtering to improve stability and sensitivity. After the receiver is the detection circuit, which filters out the valid signal and compares it with a preset threshold. Based on the result of the threshold comparison, the photoelectric component generates an output signal, which is typically a digital signal or a switch state. The output signal is used to control the voltage of the partition, thereby controlling the transmittance of that partition.

[0183] The interactive component 50 can be disposed close to the first electrode 12 or separately from the first electrode 12. For example, the interactive component 50 can be disposed on the side door of the vehicle for convenient user control; the interactive component 50 can also be virtually disposed in the vehicle's central control screen for convenient driver control. That is, in the embodiments of this disclosure, the interactive component can include physical buttons disposed on the vehicle or virtual buttons disposed on the display screen inside the vehicle.

[0184] Figure 13A This is a schematic diagram of the structure of an electrochromic unit in a dimming glass according to some embodiments of the present disclosure; Figure 13B These are transition metal elements in the periodic table that can be used as electrochromic materials according to some embodiments of this disclosure.

[0185] In some embodiments of this disclosure, the electrochromic unit 42 includes an electrochromic layer 421, an ion storage layer 423, and an electrolyte layer 422 sandwiched between the electrochromic layer and the ion storage layer; the electrochromic layer 421 changes color under the action of an electric field.

[0186] When an electric field is applied to both ends of the electrochromic unit 42, ions can move within the electrochromic unit 42, embedding / exiting from the electrochromic layer 421. Simultaneously, to achieve charge balance, charges also migrate, causing the electrochromic material to undergo a redox reaction, resulting in a color change caused by the change in valence state. The sealing material 41 is a transparent conductive sealing adhesive. This electrochromic material-based sealing material 41 can be applied to various types of smart glass, meeting users' needs for aesthetics and diversity, and enhancing the user experience.

[0187] When the electrochromic unit 42 is located within the enclosure material 41, an electric field is generated at both ends of the electrochromic layer 421 and the ion storage layer 423 due to their different positions. Ions can move within the electrochromic unit 42, embedding / exiting from the electrochromic layer 421. Simultaneously, to achieve charge balance, charges also migrate, causing a redox reaction in the electrochromic material, resulting in a color change caused by the valence state change. The most commonly used electrochromic material is a transition metal oxide. Figure 13B The periodic table lists transition metal elements that can be used as electrochromic materials, with different colored shaded boxes representing cathode and anodic electrochromic elements; among them, cathode electrochromic (Cathod... e co During the reduction process, the color of the material changes from colorless to colored, while anodic electrochromism (anodic electrochromism)... e co The opposite is true for loration materials.

[0188] Tungsten oxide (WO3) is a typical cathodic electrochromic material, possessing high color contrast, good reversibility, and excellent chemical and thermal stability, making it one of the most studied electrochromic materials to date. When cations (e.g., H+) are present... + Li + Al 3+ When electrons are injected into WO3 material, the color of WO3 changes from colorless to dark blue. This process is reversible and is shown below:

[0189] WO3 (colorless) + xLi + +xe - ←→Li x WO3 (Dark Blue)

[0190] Nickel oxide (NiO) is another common electrochromic material, often used in conjunction with tungsten oxide to provide a wider range of color changes.

[0191] Besides transition metal oxides, many conductive polymers are also good electrochromic materials, such as polyaniline (PANI), polyethylene dioxythiophene (PEDOT), as well as certain metal frameworks (MOFs) and Prussian blue and its derivatives, all of which possess electrochromic properties. Organic electrochromic materials offer a rich variety of colors, are easy to synthesize, and are inexpensive; however, their weather resistance and stability are inferior to inorganic electrochromic materials, especially under ultraviolet light, where the breaking of covalent bonds easily leads to fading, yellowing, and degradation. Therefore, appropriate electrochromic materials can be selected based on different scenarios and color requirements to meet diverse design needs.

[0192] Figure 14 This is a schematic diagram of the driving waveform of a dimming glass according to some embodiments of the present disclosure.

[0193] In some embodiments of this disclosure, the dimming glass 10 is driven by a sine wave, such as... Figure 14 As shown, the transmittance of the dimming glass 10 is controlled by applying a sinusoidal voltage signal with a certain peak voltage (e.g., 12V) and a certain frequency (e.g., 50Hz) to the first electrode 12 and the second electrode 22 of the dimming glass 10.

[0194] Figure 15 It is a graph showing the change in transmittance of the first dimming zone in a dimming glass according to different exemplary embodiments of the present disclosure as a function of driving voltage.

[0195] Reference Figure 15 In the liquid crystal layer 31 of the first dimming region 301, the VT (drive voltage-transmittance) curve of the VA-type PI liquid shows that the transmittance gradually increases with the increase of the drive voltage. The VT curve of the TN-type PI liquid shows that the transmittance gradually decreases with the increase of the drive voltage. PI liquid is a polyimide, mainly used to fabricate the guide layer of a liquid crystal display screen, aligning liquid crystal molecules in a regular direction under the action of an electric field. VA type refers to Vertical Alignment type, and TN type refers to Twisted Nematic type. For example, the dye-based liquid crystal dimming glass uses an upper and lower electrode electric field-driven liquid crystal method, with a structure similar to the upper and lower electrode structure of the TN-type product; however, the dye-based liquid crystal dimming glass provides full-area dimming, requiring separate voltages applied to the upper and lower substrates for control.

[0196] For example, by applying an electrical signal to the first electrode 12 and the second electrode 22, an electric field is generated between the first electrode 12 and the second electrode 22. The transmittance of the first dimming region 301 and the second dimming region 401 changes with different applied driving voltages. Further, referring to… Figures 9A-9B , Figures 10A to 10C and Figures 11A-11B By applying a driving voltage independently to each sub-electrode, the state switching of the dimming glass 10 can be achieved.

[0197] In embodiments of this disclosure, the dimming glass technology is applied to vehicles. Specifically, at least one of the side windows, rear windshield, sunroof, and panoramic sunroof can be the aforementioned dimming glass. Based on this, by adjusting the light transmittance of the dimming glass, the effect of protecting privacy while enhancing aesthetics can be achieved. For example, in scenarios where the vehicle is turning, changing lanes, or traveling at high speed, the light transmittance of the dimming glass can be increased, allowing the driver to observe the external environment more clearly, thereby improving driving safety. In scenarios where there are people resting inside the vehicle or other vehicles are nearby, the light transmittance of the dimming glass can be decreased, thus improving the privacy protection of the occupants.

[0198] Figure 16 This is a schematic diagram of the structure of a dimming system for a vehicle according to different exemplary embodiments of the present disclosure.

[0199] Some embodiments of this disclosure provide a dimming system 1600 for a vehicle, the system including a dimming glass 10 and a controller 1610. The dimming glass 10 can be based on the above... Figures 6A to 6C , Figures 7A-7B , Figures 8A-8B , Figures 9A-9B , Figures 10A to 10C and Figures 11A-11B One or more embodiments of the present invention are implemented and installed on a vehicle, and the controller 1610 is electrically connected to the first electrode 12 and the second electrode 22 of the dimming glass 10.

[0200] The dimming system 1600 provided according to the embodiments of this disclosure can realize the function of dynamically adjusting the shading area of ​​the vehicle window, thereby meeting the different needs of different passengers / drivers.

[0201] like Figure 16 As shown, the dimming system 1600 may include a dimming glass 10 and a controller 1610. The controller 1610, the vehicle infotainment system 1620, and the input module 1630 can be electrically connected to each other.

[0202] For example, the input module 1630 may include an input device integrated into the vehicle, such as an interactive component, a voice input device, a keyboard input device, or a mouse input device. Alternatively, the input module 1630 may also include a user-used terminal device, such as a smartphone, tablet, wearable smart bracelet, wearable smart headset, virtual reality device, or augmented reality device. The terminal device can establish a communication connection with the controller 1610 or the vehicle infotainment system 1620 using network protocols or Bluetooth protocols to obtain user input information.

[0203] For example, the user's input information may include natural language indicating subjective feelings, such as "It's too dark inside the car, make it brighter" or "The sunlight is too bright, adjust it." The vehicle infotainment system 1620 can further acquire vehicle driving information, such as adjusting the light transmittance and / or occupancy of at least one zone on that side if the brightness on one side decreases. According to embodiments of this disclosure, the vehicle infotainment system 1620 can interact with the user or the outside world in a timely manner and switch the preset state of the dimming glass to meet diverse needs.

[0204] Reference Figure 16In this embodiment, the first electrode 12 of the dimming glass 10 includes a second sub-electrode 121, which supports one or more zones in the horizontal direction of the current paper display. The area / number of each zone is adjustable, and the adjustable level is determined by the number of second sub-electrodes 122, for example, at least two independently controllable second sub-electrodes 122. The more second sub-electrodes 122 there are, the finer the control of dynamic switching between zones. In addition, the light transmittance of each zone can be fixed, or it can support level adjustment or stepless adjustment.

[0205] Figure 17 This is a schematic diagram of the circuit structure of the controller in a dimming glass according to some embodiments of the present disclosure.

[0206] In the controller 1610, the photoelectric component responds to user actions on it, generating a control signal. A current sensor filters out the valid signal and sends it to the microcontroller. After the power input voltage is applied, a BUCK chip and an LDO (low dropout linear regulator) are used for step-down conversion, which is then connected to a full-bridge chip. The microcontroller performs sinusoidal pulse width modulation, and after passing through an LC filter circuit, a sinusoidal wave drive output is generated, such as... Figure 14 As shown.

[0207] The controller 1610 performs PWM dimming based on received current changes. The principle of PWM dimming is based on pulse control of current. When current is transmitted to light in the form of pulses at a fixed frequency, the width (duty cycle) of each pulse determines the brightness of the light. A longer pulse width means higher brightness, while a shorter pulse width means lower brightness, thereby changing the light transmittance of the window and achieving the purpose of multi-channel zone dimming of the window.

[0208] Figures 18A to 18D These are schematic diagrams of different vehicle models according to some exemplary embodiments of this disclosure.

[0209] like Figure 18A The vehicle of the first model is shown. Figure 18B The second model of the vehicle is shown. Figure 18C The third model of the vehicle is shown. Figure 18D A vehicle of the fourth model type is shown. In some embodiments, for example... Figures 18A to 18D These are small cars, mid-size cars, large cars, and luxury cars.

[0210] In some embodiments, the dimming glass 10 includes at least one of the following: a side windshield 1801 located on the side of the vehicle, a rear windshield 1802 located at the rear of the vehicle, a sunroof 1803 located on the roof of the vehicle, and a front windshield 1804 located at the front of the vehicle. Exemplarily, the dimming glass 10 can be positioned in at least one of the above-mentioned locations according to the specific needs of the driver or passengers in the vehicle, in order to achieve a dynamic shading effect.

[0211] In some embodiments, the dimming glass 10 includes at least two of the following: at least one side windshield 1801 located on the side of the vehicle, a rear windshield 1802 located at the rear of the vehicle, a sunroof 1803 located on the top of the vehicle, and a front windshield 1804 located at the front of the vehicle. Furthermore, at least two dimming glass 10s can be independently controlled. Exemplarily, independently controlling at least two dimming glass 10s can provide a variety of combined shading effects to meet personalized needs. Furthermore, it also allows for batch switching of the dimming glass 10's state, improving operational convenience.

[0212] Preferably, the dimming glass 10 is applied to the windshield 1804 on the front side of the vehicle. For example, when the vehicle is suddenly exposed to strong oncoming light while driving, the driver can quickly reduce the light transmittance of the windshield 1804, improving driving safety; in bright sunlight, by reducing the light transmittance of the windshield 1804, the front passengers are protected from direct sunlight, greatly improving their comfort.

[0213] In some embodiments of this disclosure, the dynamic pattern in the dimming glass 10 changes along a first direction at predetermined partition intervals, the first direction being the direction from the top side of the vehicle toward the ground.

[0214] The dynamic pattern changing from top to bottom greatly simplifies dimming operations for users. For example, when dimming the side window when it's halfway up, the lower half of the window is recessed into the door, making it difficult to dim from bottom to top using the touch-sensitive photoelectric components. Dimming from top to bottom solves this problem. Another example is when driving on a sunny morning or evening when sunlight is glaring. Drivers typically lower the sun visor to block the sun's rays. For front passengers and rear passengers, sunlight is primarily concentrated on the upper half of the window. If dimming from bottom to top using the touch-sensitive components were done, the lower area would need to be dimmed before the upper area could be adjusted, making the operation cumbersome. Dimming from top to bottom is much more convenient and efficient.

[0215] Figure 19 This is a schematic diagram of the structure of a dimming glass according to some exemplary embodiments of the present disclosure.

[0216] like Figure 19 The dimming glass 10 shown in Figure a has a single-cell structure 1801, including a single first substrate 11, a single second substrate 21, a single first electrode 12, a single second electrode 22, and a single dimming component 3. Figure 19The dimming glass 10 shown in Figure b is a dual-cell structure, which is formed by stacking two single-cell structures. The rubbing directions of the two cells are perpendicular to each other. For example, it can be achieved by coating four glass sheets with ITO and PI liquid respectively, adding BS (or PS) and liquid crystal cells in the middle, and then stacking two single cells.

[0217] Figure 20 This is a flowchart of a method for controlling a dimming glass according to some further exemplary embodiments of the present disclosure.

[0218] like Figure 20 As shown, the control method of this embodiment may include operations S2001 to S2003.

[0219] In operation S2001, user input information is obtained.

[0220] In operation S2002, an electrical signal corresponding to the user's input information is generated.

[0221] In operation S2003, an electrical signal is applied to at least one of the first dimming component and the second dimming component to cause the dimming glass to switch to a predetermined state. In the predetermined state, the dimming glass has a predetermined pattern, which includes a pattern displayed by at least a portion of the first dimming area and by at least a portion of the second dimming area. At least one of the following properties of the predetermined pattern is determined in response to user input: the shape of the predetermined pattern, the transmittance of the predetermined pattern, and the dynamic properties of the predetermined pattern.

[0222] In some embodiments of this disclosure, obtaining user input information includes: obtaining user operations performed on a photoelectric component disposed in a dimming glass; generating an electrical signal corresponding to the input information based on the user input information includes: generating a control signal based on the obtained user operations, the control signal being used to control the transmittance of the partition, the transmittance difference, or the transmittance change rate, wherein the user operations include at least one of the following operations: single click, long press, slide, long press followed by slide.

[0223] Figure 21 This is a flowchart of a method for controlling the dimming glass to vary with a predetermined rate of light transmission according to some embodiments of the present disclosure.

[0224] Users interact with the dimming glass through photoelectric components. First, a first initial transmittance is set for the first dimming zone. Zone 1 changes with a predetermined transmittance change rate, from the first initial transmittance to A with the set transmittance change rate, and finally reaches a predetermined fixed value B. The transmittance of zone 2 to the kth zone jumps directly to this fixed value B.

[0225] While some embodiments based on the general inventive concept of this disclosure have been illustrated and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the general inventive concept of this disclosure, the scope of which is defined by the claims and their equivalents.
