[0026] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0030] In dimming glass with multiple dimming zones, the dimming characteristics of dimming zones located in different positions may vary due to different user needs or manufacturing processes. However, generally speaking, the most comfortable state for the user is when all dimming zones of the dimming glass have a relatively consistent transmittance.

[0031] Based on this, this application proposes a dimming glass and a vehicle that can make the transmittance of different areas of the dimming glass consistent, thereby improving the user experience.

[0032] In one embodiment, such as Figure 1 As shown, this application proposes a dimming glass, comprising: at least two dimming areas, each dimming area being independently dimmed, and the transmittance difference between any two dimming areas under the action of a corresponding target electronic control signal being less than or equal to a first preset difference.

[0033] Specifically, the dimming glass of this application is a glass with dimming control function. The dimming glass consists of at least two dimming areas (dimming area 1, dimming area 2, ..., dimming area N), and can be installed on different vehicles. The dimming glass is connected to a control component. The dimming areas are used to adjust their transmittance under the action of the electrical control signals sent by the control component, so that each dimming area can be dimmed independently. The control component is used to send a corresponding electrical control signal to each dimming area. After receiving the corresponding electrical control signal, the dimming area can switch from a colored state to a faded state and from a faded state to a colored state, or it is not limited to colored and faded states, and under different electrical control signals, it can present a third or even more intermediate optical states.

[0034] When the dimming glass of this application is in operation, the control component sends a preset target electronic control signal to the corresponding dimming area. Each dimming area corresponds to one target electronic control signal. The transmittance difference between any two dimming areas under the action of the corresponding target electronic control signal is less than or equal to a first preset difference. When the transmittance difference between two dimming areas is less than or equal to the first preset difference, the transmittance of the two dimming areas is relatively consistent, and the two dimming areas exhibit similar optical characteristics. Through the control of the target electronic control signal, the transmittance of all dimming areas in the dimming glass can be made relatively consistent. In some embodiments, the first preset difference is less than or equal to 0.5%. In some embodiments, the first preset difference is set to 0.3%. In some embodiments, the first preset difference is set to 0.1%. It is understood that when calculating the transmittance difference between two dimming areas, the larger transmittance value is subtracted from the smaller transmittance value.

[0035] In the aforementioned dimming glass, by setting at least two dimming areas that can be dimmed independently on the dimming glass, and ensuring that the transmittance difference between any two dimming areas under the action of the corresponding target electronic control signal is less than or equal to a first preset difference, the consistency of transmittance between different dimming areas is guaranteed when the dimming glass is in use, thereby improving the user experience.

[0036] It is understandable that different dimming zones may have the same or different electronic control signals due to differences in their dimming principles or structures. Differences in electronic control signals can stem from different input characteristics, such as the difference between DC and AC power supply characteristics; or, when the input characteristics are the same, different frequencies, such as 50Hz and 120Hz. In some embodiments, the electronic control signals differ when the frequency difference is greater than or equal to 5Hz; or, when the input characteristics and frequency are the same, different voltage magnitudes, such as 24V and 60V. In some embodiments, the electronic control signals differ when the voltage difference is greater than or equal to 2V; or, when the input characteristics, frequency, and voltage are the same, different waveforms, such as sine waves and square waves; or, when the input characteristics are the same, different open circuit voltages (OCV), such as 0.1V and 0.3V. In some embodiments, the electronic control signals differ when the open circuit voltage difference is greater than or equal to 0.1V.

[0037] In one embodiment, at least one dimming area has a haze level in the bright state that is less than or equal to a preset haze level. Specifically, haze is an indicator of the transparency of a dimming area, representing the degree to which light deviates from the incident direction due to scattering within or on the surface of the dimming area. The lower the haze value, the more transparent the dimming area and the clearer the visual effect. In this embodiment of the dimming glass, at least one dimming area has a haze level in the bright state that is less than or equal to the preset haze level to meet the user's visual effect requirements for a local dimming area. In some embodiments, when the dimming glass has at least two dimming areas, at least two dimming areas have a haze level in the bright state that is less than or equal to the preset haze level. In some other embodiments, the haze level of all dimming areas of the dimming glass in the bright state is less than or equal to the preset haze level, resulting in high overall transmittance of the dimming glass in the bright state and ensuring a good visual effect for the user. In some embodiments, the haze level of the dimming area can be measured using the measurement method of GBT 2410-2008. In some embodiments, the preset haze level is 5% to 15%. In some embodiments, the preset haze level is set to 15%. In some embodiments, the preset haze level is set to 10%. In some embodiments, the preset haze is set to 5%.

[0038] In one embodiment, the difference in haze between any two dimming areas in a bright state is less than or equal to a second preset difference. Specifically, in this embodiment, all dimming areas of the dimming glass have a consistent haze performance in a bright state. This setting makes the user's visual effect more consistent and improves the user experience. In some embodiments, the second preset difference is less than or equal to 3%. In some embodiments, the second preset difference is set to 2%. In some embodiments, the second preset difference is set to 1%.

[0039] In one embodiment, the haze of all dimming areas in the bright state is less than or equal to a preset haze, and the difference in haze between any two dimming areas in the bright state is less than or equal to a second preset difference. Specifically, the dimming glass in this embodiment maintains consistent haze while ensuring high transmittance of the dimming areas in the bright state, further enhancing the user experience.

[0040] In one embodiment, such as Figure 2 As shown, the dimming glass includes a first glass layer 110, a first adhesive layer 120, a photoelectric functional layer 130, a second adhesive layer 140, and a second glass layer 150 stacked in sequence. The photoelectric functional layer 130 is used to form at least two dimming areas.

[0041] Specifically, in this embodiment, the dimming glass possesses independent dimming capabilities for different areas by providing a photoelectric functional layer 130 that can form at least two dimming regions. The first glass layer 110 serves as the outermost protective layer, resisting impacts, scratches, and chemical corrosion from the external environment, providing physical protection for the internal photoelectric functional layer 130 and other film layers. The first adhesive layer 120 tightly bonds the first glass layer 110 and the photoelectric functional layer 130 together, forming a stable composite structure. The second adhesive layer 140 tightly bonds the photoelectric functional layer 130 and the second glass layer 150 together, forming a complete composite structure. The second glass layer 150 serves as the inner layer of the composite structure, providing additional physical protection and support while maintaining the overall transparency of the structure. In some embodiments, the first adhesive layer 120 and the second adhesive layer 140 can be made of one of polyvinyl butyral (PVB), polyethylene-vinyl acetate copolymer (EVA), or ethylene-methacrylic acid copolymer (SGP). In some embodiments, the thickness and color of the first glass layer 110 and the second glass layer 150 can be set according to specific parameter requirements. For example, it can be 2.1mm clear glass, 2mm clear glass, 1.8mm gray glass, 1.6mm gray glass, etc.

[0042] In one embodiment, such as Figure 3 As shown, the dimming glass further includes an adhesive edge-patching layer 160, and the photoelectric functional layer 130 is disposed between the first adhesive layer 120 and the second adhesive layer 140 via the adhesive edge-patching layer 160. Specifically, this embodiment also additionally provides an adhesive edge-patching layer 160 for filling and fixing the edges or internal gaps of the photoelectric functional film in the photoelectric functional layer 130, preventing gaps or displacement between the photoelectric functional film and the adhesive film, and enhancing the edge sealing of the composite structure. In some embodiments, the adhesive edge-patching layer 160 may be one of polyvinyl butyral (PVB), polyethylene-polyvinyl acetate copolymer (EVA), or ethylene-methacrylic acid copolymer (SGP).

[0043] In one embodiment, such as Figure 4 As shown, the optoelectronic functional layer 130 includes a first substrate layer 131, a first conductive layer 132, a dimming element layer 133, a second conductive layer 134, and a second substrate layer 135, which are stacked sequentially.

[0044] Specifically, in this embodiment, the optoelectronic functional layer 130 uses a first substrate layer 131 and a second substrate layer 135 as film structure carriers, which are respectively bonded to the first adhesive layer 120 and the second adhesive layer 140, and simultaneously serve to support the first conductive layer 132 and the second conductive layer 134. The first conductive layer 132 and the second conductive layer 134 are used to transmit electrical control signals to the dimming element layer 133, and can be indium tin oxide (ITO), silver nanowires (AgNW), metal mesh, etc. By setting the specific structure of the first conductive layer 132, the dimming element layer 133, and the second conductive layer 134, the optoelectronic functional layer 130 can form at least two dimming regions and complete independent dimming.

[0045] In one embodiment, the first conductive layer 132 and / or the second conductive layer 134 are divided into at least two conductive regions, which are used to form a dimming region. Specifically, in this embodiment, the corresponding dimming region is formed by dividing the first conductive layer 132 and / or the second conductive layer 134 in the photoelectric functional layer 130 into at least two conductive regions.

[0046] In some embodiments, the first conductive layer 132 or the second conductive layer 134 is divided into at least two conductive regions, while the corresponding other conductive layer does not need to be divided. In this manner, each conductive region corresponds to a dimming region. The control component can control the light in different dimming regions by applying different electrical control signals to the different conductive regions. For example, ... Figure 4 and Figure 5 As shown, the first conductive layer 132 is divided into two non-conductive conductive regions. Correspondingly, two dimming regions (dimming region 1 and dimming region 2) will be formed on the photoelectric functional layer 130.

[0047] In some embodiments, such as Figure 6As shown, the first conductive layer 132 is divided into at least two first regions, and the second conductive layer 134 is divided into at least two second regions, with the first and second regions aligned. Specifically, in this embodiment, both the first conductive layer 132 and the second conductive layer 134 are divided into multiple conductive regions, and the first regions in the first conductive layer 132 and the second regions in the second conductive layer 134 have the same shape and size and are aligned. A set of aligned first and second regions can form a dimming region. In some other embodiments, the shape and size of the first and second regions may be different. For example, the first region may completely cover the second region, in which case the formed dimming region is similar in size to the smaller second region. In some embodiments, when separating the first conductive layer 132 and / or the second conductive layer 134, processes such as etching, laser engraving, and polishing plate exposure can be used depending on the material of the conductive layer.

[0048] It is understood that in the above embodiments, when at least two dimming regions are formed by separating the first conductive layer 132 and / or the second conductive layer 134 into at least two conductive regions, the dimming element layer 133 can be configured as only one type of optical functional film. Different conductive regions can be made to present multiple dimming regions by applying different electrical control signals to the same optical functional film.

[0049] In one embodiment, such as Figure 7 As shown, the dimming element layer 133 includes at least two optical functional films, each of which is used to form a dimming area.

[0050] Specifically, the photoelectric functional layer 130 contains a photoelectric functional film with dimming capabilities. Under the influence of an electronically controlled signal, the film can change its transmittance. The photoelectric functional film can be one of the following: dye-dispersed liquid crystal film (LC), white polymer-dispersed liquid crystal film (PDLC), dye-polymer-dispersed liquid crystal film (D-PDLC), suspended particle film (SPD), or electrochromic film (EC). Different photoelectric functional films possess different dimming performance. When the dimming element layer 133 is composed of at least two photoelectric functional films, to enable independent dimming, the conductive regions of the conductive layer supplying power to the multiple photoelectric functional films are not interconnected. By independently controlling different photoelectric functional films, at least two dimming regions can be formed on the dimming glass.

[0051] In one embodiment, the difference in the highest transmittance of any two optical functional films is greater than or equal to a third preset difference, or the transmission color difference of any two optical functional films is greater than or equal to a fourth preset difference.

[0052] Specifically, in the dimming glass of this application, the difference in the highest transmittance of any two optical functional films in multiple dimming areas is greater than or equal to a third preset difference, or the transmission color difference of any two optical functional films is greater than or equal to a fourth preset difference. In some embodiments, the transmittance of the optical functional films can be measured using the measurement method of GBT 2410-2008. In some embodiments, the color difference of the optical functional films can be measured using the measurement method of GBT 7921-2008. In some embodiments, the third preset difference is 2% to 4%. In some embodiments, the third preset difference is set to 4%. In some embodiments, the third preset difference is set to 2%. In some embodiments, the fourth preset difference is 2 to 5. In some embodiments, the fourth preset difference is set to 5. In some embodiments, the fourth preset difference is set to 2. When the difference in the highest transmittance or the transmission color difference of two optical functional films meets the above conditions, the two optical functional films can be considered to be of different types. It is understood that different optical functional films are not limited to different materials; optical functional films of the same material may also be considered different optical functional films due to differences including, but not limited to, different suppliers, different transmittance ranges, and different manufacturing processes. This embodiment can maintain the consistency of transmittance in multiple dimming areas even when the dimming characteristics of the optical functional film are different, thus improving the user experience.

[0053] In one embodiment, such as Figure 8 As shown, when the dimming element layer 133 includes at least two optical functional films, for each optical functional film, its corresponding conductive layer can also be divided into multiple conductive regions, so that the same optical functional film can also form different dimming regions.

[0054] The advantages of the dimming glass of this embodiment will be described in detail below with a specific example. The dimming element layer 133 uses only one type of optical functional film.

[0055] In one embodiment, the dimming element layer 133 uses a dye liquid crystal film (LC) with a transmittance ranging from 0.7% to 17%, and its conductive layer is divided into 10 conductive regions. Correspondingly, the dimming glass is also divided into 10 dimming regions. The first glass layer 110 and the second glass layer 150 are both made of 1.8mm thick green glass. The first adhesive layer 120, the second adhesive layer 140, and the adhesive edge layer 160 are all made of transparent PVB. The electrical control signal is a 50Hz sinusoidal AC signal. The transmittance of the 10 dimming regions under the same electrical control signal is shown in the table below:

[0056]

[0057] As shown in the table above, in state 1, when all 10 dimming areas are operating under a 12V electronic control signal, the maximum transmittance difference between different dimming areas in the dimming glass reaches 0.9%; in state 2, when all 10 dimming areas are operating under a 3V electronic control signal, the maximum transmittance difference between different dimming areas in the dimming glass reaches 1.05%.

[0058] This application achieves independent dimming by applying a target electronic control signal to each dimming area. The transmittance of the 10 dimming areas under different electronic control signals is shown in the table below:

[0059]

[0060] As shown in the table above, in state 1, when the 10 dimming areas operate under different electronic control signals, the maximum transmittance difference between the different dimming areas in the dimming glass is only 0.1%; in state 2, when the 10 dimming areas operate under different electronic control signals, the maximum transmittance difference between the different dimming areas in the dimming glass is 0.3%. In both states, the transmittance difference between any two dimming areas is less than the first preset difference (0.5%), ensuring the consistency of transmittance between different dimming areas and improving the user experience.

[0061] The advantages of the dimming glass in this embodiment will be described in detail below with reference to another specific embodiment. The dimming element layer 133 employs various types of optical functional films.

[0062] In one embodiment, the photoelectric functional layer 130 is composed of an electrochromic film (EC) with a transmittance ranging from 0.3% to 13% and a dye liquid crystal film (LC) with a transmittance ranging from 0.7% to 17%. The first adhesive layer 120, the second adhesive layer 140, and the adhesive patch layer 160 are all transparent PVB, and the first glass layer 110 and the second glass layer 150 are both 1.8mm thick green glass. The difference in the maximum transmittance of the two photoelectric functional films is 4%, which exceeds a third preset difference (2%), therefore they can be considered as two different photoelectric functional films. The EC material photoelectric functional film uses open circuit voltage (OCV) as the electrical control signal, while the LC material photoelectric functional film uses sinusoidal AC voltage as the electrical control signal. The specific product combination parameters are shown in the table below:

[0063]

[0064] As shown in the table above, in state 1, the transmittance difference between the two dimming areas is only 0.1% under different electronic control signals; in state 2, the transmittance difference between the two dimming areas is only 0.2% under different electronic control signals. In both states, the transmittance difference between the two dimming areas is less than the first preset difference (0.5%), ensuring the consistency of transmittance between different dimming areas and improving the user experience.

[0065] In one embodiment, the photoelectric functional layer 130 is composed of a dye-polymer dispersed liquid crystal film (D-PDLC) with a transmittance ranging from 5% to 35% and a dye-liquid crystal film (LC) with a transmittance ranging from 1.6% to 21%. The first adhesive layer 120, the second adhesive layer 140, and the adhesive edge layer 160 are all transparent PVB, and the first glass layer 110 and the second glass layer 150 are both 1.8mm gray glass. The difference in the maximum transmittance of the two photoelectric functional films is 14%, which exceeds the third preset difference (2%), therefore they can be considered as two different photoelectric functional films. The D-PDLC photoelectric functional film uses a square wave AC voltage as the electrical control signal, while the LC photoelectric functional film uses a sinusoidal AC voltage as the electrical control signal. The specific product combination parameters are shown in the table below.

[0066]

[0067] As shown in the table above, in state 1, under different electronic control signals, the transmittance difference between the two dimming areas is only 0.2%, which is less than the first preset difference (0.5%), ensuring the consistency of transmittance between different dimming areas and improving the user experience.

[0068] In one embodiment, the photoelectric functional layer 130 comprises a dye-polymer dispersed liquid crystal film (D-PDLC) with a transmittance ranging from 8% to 52% and two dye-polymer dispersed liquid crystal films (LC) with transmittance ranging from 10% to 75%. The first glass layer 110 and the second glass layer 150 are both 1.8mm thick white glass. The first adhesive layer 120 and the second adhesive layer 140 are both gray films, and the adhesive edge-patching layer 160 is transparent PVB. The D-PDLC photoelectric functional film uses a square wave AC voltage as the electrical control signal, while the LC photoelectric functional film uses a sinusoidal AC voltage as the electrical control signal. Specific product combination parameters are shown in the table below.

[0069]

[0070] As shown in the table above, under state 1, the maximum transmittance difference between the three dimming zones is 0.5% under different electronic control signals, which is equal to the first preset difference (0.5%), ensuring the consistency of transmittance among the three dimming zones and improving the user experience.
