Therefore, the features defined with "first" and "second" can explicitly or implicitly include at least one of the features.

[0028] The application provides a glass, a head-up display assembly and a vehicle, which are described in detail below. It should be noted that the description order of the following embodiments is not regarded as the preferred order of the embodiments of the application. Moreover, the description of each embodiment in the following embodiments has its own focus, and the parts not described in detail in a certain embodiment can be referred to the relevant description of other embodiments.

[0029] Please refer to Figure 1 , and can be combined with Figure 2 The embodiments of the application provide a glass which is used in cooperation with a structure such as an imaging light source to realize a head-up display function. The image projected on the glass by the imaging light source can be well displayed.

[0030] Here, the glass comprises a first light-transmitting substrate 100, a second light-transmitting substrate 200, an electrochromic layer 300 and a head-up display layer 400.

[0031] The first light-transmitting substrate 100 can be a planar substrate or a curved substrate, and is usually transparent. The first light-transmitting substrate 100 can be made of glass, organic glass or PET or PC or PMMA or PI, and of course, the examples in the embodiments do not improperly limit the materials.

[0032] Similarly, the second light-transmitting substrate 200 can be a planar substrate or a curved substrate, and is usually transparent. The second light-transmitting substrate 200 can be made of glass, organic glass or PET or PC or PMMA or PI, and of course, the examples in the embodiments do not improperly limit the materials.

[0033] The electrochromic layer 300 is arranged between the first light-transmitting substrate 100 and the second light-transmitting substrate 200. The principle of the electrochromic layer 300 is that by applying a voltage, ions migrate into or out of the electrochromic layer 300, thereby causing the valence number of the electrochromic material to change, thereby producing color change.

[0034] Here, the electrochromic layer 300 is arranged as at least one layer, and in the case of being arranged in multiple layers, the electrochromic layers 300 can be bonded by an interlayer 310, and of course, the examples in the embodiments do not improperly limit the materials.

[0035] The head-up display layer 400 is arranged on the side of the second light-transmitting substrate 200 away from the first light-transmitting substrate 100.

[0036] Further, when the projection is projected to the head-up display layer 400 by the imaging light source, a dark and adjustable backlight can be formed by the light adjustment characteristic of the electrochromic layer 300. That is, by adjusting the range of the light transmittance of the electrochromic layer 300, the display brightness of the head-up display layer 400 is improved. If the electrochromic layer 300 is replaced by other light-emitting layers, since the light-emitting layers can only improve their own brightness and do not have the function of reducing the background brightness, the display brightness of the head-up display layer 400 cannot be improved. In addition, in the state that the external environment is relatively dark at night, the electrochromic layer 300 can also be adjusted to brighten the visible area of the user, without affecting the display of the head-up display layer 400. In addition, due to the arrangement of the electrochromic layer 300, anti-glare protection can also be formed in the external strong light environment.

[0037] In some embodiments, the glass further comprises an inorganic sealing layer arranged on the side of the first light-transmitting substrate 100 close to the electrochromic layer 300. The arrangement of the inorganic sealing layer can reduce the influence of the external packaging glass on the transmittance, increase the transmittance change range of the electrochromic device, and also improve the sealing protection performance of the electrochromic layer 300, reducing the risk of aging and failure of the electrochromic layer 300 due to external water vapor and the like.

[0038] In some embodiments, the head-up display layer 400 comprises a plurality of first light-transmitting material layers and second light-transmitting material layers arranged in sequence. The material of one of the first light-transmitting material layers and the second light-transmitting material layers is an oxide, and the material of the other is a nitride oxide. For example, the material of the first light-transmitting material layer is an oxide, and the material of the second light-transmitting material layer is a nitride oxide.

[0039] In some examples, the aforementioned oxide is selected from the oxides of silicon, niobium, titanium, tungsten, tin, and zirconium; and the aforementioned nitride oxide is selected from the nitride oxides of silicon, niobium, titanium, tungsten, tin, and zirconium. For example, the first light-transmitting material layer is made of an oxide of silicon, and the second light-transmitting material layer is made of a nitride oxide of silicon. It can be understood that the materials used by the first light-transmitting material layer and the second light-transmitting material layer can correspondingly contain the same element or can not contain the same element, and the examples in the embodiments of the present application do not constitute improper limitations.

[0040] Here, the first light-transmitting material layer and the second light-transmitting material layer are colorless optical films, and one of them is made of a nitride oxide of silicon, niobium, titanium, tungsten, tin, or zirconium, so that the color of the head-up display layer 400 is closer to neutral. In addition, the optical properties of the head-up display layer 400 are better, and the wear resistance is better.

[0041] In some embodiments, a first anti-reflection layer 510 is further arranged on the side of the first light-transmissive substrate 100 away from the second light-transmissive substrate 200. Exemplarily, the material of the first anti-reflection layer 510 can be selected from magnesium fluoride, silicon oxide, chromium oxide, tin oxide, niobium oxide, titanium oxide, etc. The arrangement of the first anti-reflection layer 510 helps to reduce the reflection of visible light, especially light with a wavelength of 550 nm. When used as a car glass, the reflection of human shadow can be effectively reduced, and the driving safety can be improved.

[0042] In addition, in some embodiments, a first hardening layer 810 can be further arranged on the outer side of the first anti-reflection layer 510 to protect the film layers.

[0043] In some embodiments, referring to Figure 3 The glass further comprises a third light-transmissive substrate 600 arranged on the side of the head-up display layer 400 away from the second light-transmissive substrate 200.

[0044] Similar to the first light-transmissive substrate 100 and the second light-transmissive substrate 200, the third light-transmissive substrate 600 can be a planar substrate or a curved substrate, and is usually transparent. The third light-transmissive substrate 600 can be made of glass, organic glass, PET, PC, PMMA, PI, etc. Of course, the examples in the present embodiment do not limit the material.

[0045] Here, a hollow area 710 is arranged between the third light-transmissive substrate 600 and the head-up display layer 400. The hollow area 710 serves as an imaging buffer area. In addition, the arrangement of the hollow area 710 helps the glass to meet the structural requirements of the vehicle body, especially when the glass is used as a head-up display glass for the roof of a vehicle to achieve a projection theater effect, etc.

[0046] In some embodiments, a support layer 700 is arranged between the second light-transmissive substrate 200 and the third light-transmissive substrate 600. The second light-transmissive substrate 200, the third light-transmissive substrate 600, and the support layer 700 together enclose a containing space, and the head-up display layer 400 and the hollow area 710 are located in the containing space.

[0047] The support layer 700 can be hard or flexible, such as aluminum profile, etc., or flexible spacer, etc.

[0048] In some embodiments, a second anti-reflection layer 520 is further arranged on the side of the third light-transmissive substrate 600 away from the second light-transmissive substrate 200. Similar to the first anti-reflection layer 510, the material of the second anti-reflection layer 520 can be selected from magnesium fluoride, silicon oxide, chromium oxide, tin oxide, niobium oxide, titanium oxide, etc. The arrangement of the second anti-reflection layer 520 helps to reduce the reflection of visible light, especially light with a wavelength of 550 nm.

[0049] In addition, in some embodiments, the outer side of the second anti-reflection layer 520 can also be provided with a second hardening layer 820 to protect the film layers. Exemplarily, the outermost layers on both sides of the entire glass can be the first hardening layer 810 and the second hardening layer 820, respectively.

[0050] In order to better achieve the technical effects of the embodiments of the present application, please refer to Figure 3 Some embodiments of the present application also provide a head-up display assembly, which includes the glass provided in any of the preceding embodiments and an imaging light source used for projecting onto the head-up display layer 400.

[0051] In some embodiments, the imaging light source is arranged on the signed third light-transmitting substrate 600 close to the side of the head-up display layer 400.

[0052] In some embodiments, the imaging light source can be a P-hud projector or a Micro LED or a Mini LED or a metal oxide cold light source, etc. As long as it can project an optical image onto the head-up display layer 400, the examples in the present embodiment do not constitute undue limitation.

[0053] In order to better achieve the technical effects of the embodiments of the present application, some embodiments of the present application also provide an automobile, which includes a vehicle body and the glass provided in any of the preceding embodiments. In the case of need, any glass on the vehicle body can adopt the glass provided in any of the preceding embodiments.

[0058] The electrochromic layer 300 is arranged between the first light-transmitting substrate 100 and the second light-transmitting substrate 200, and is used to adjust the light transmittance of the glass. When a voltage is applied, the electrochromic material changes color, thereby changing the light transmittance of the glass.

[0059] The head-up display layer 400 is arranged on the side of the second light-transmitting substrate 200 away from the first light-transmitting substrate 100, and is used to realize the head-up display function.

[0060] Specifically, the oxide can be selected from the oxides of silicon, niobium, titanium, tungsten, tin, and zirconium; and the nitride oxide can be selected from the nitride oxides of silicon, niobium, titanium, tungsten, tin, and zirconium.

For example, the first anti-reflection layer 510 can be selected from magnesium fluoride.

[0062] The glass of the present embodiment further includes an inorganic sealing layer arranged on the side of the first light-transmitting substrate 100 close to the electrochromic layer 300. The inorganic sealing layer is used to prevent moisture and oxygen from entering the electrochromic layer 300, thereby prolonging the service life of the electrochromic layer 300. The inorganic sealing layer can be selected from materials such as silicon dioxide and silicon nitride.

[0063] The glass of the present embodiment further includes a third light-transmitting substrate 600 arranged on the side of the head-up display layer 400 away from the second light-transmitting substrate 200.

[0064] A hollow region 710 is arranged between the third light-transmitting substrate 600 and the head-up display layer 400. A support layer 700 is arranged between the second light-transmitting substrate 200 and the third light-transmitting substrate 600, and the second light-transmitting substrate 200, the third light-transmitting substrate 600 and the support layer 700 jointly enclose a containing space, and the head-up display layer 400 and the hollow region 710 are located in the containing space. The support layer 700 can adopt a ring structure, and the material can be metal, plastic or glass.

[0065] The second anti-reflection layer 520 is further arranged on the side of the third light-transmitting substrate 600 away from the second light-transmitting substrate 200. The second anti-reflection layer 520 is used to reduce the reflection of light and improve the light transmittance of the glass. The material of the second anti-reflection layer 520 can be the same as that of the first anti-reflection layer 510, and is selected from magnesium fluoride, an oxide of silicon, an oxide of chromium, an oxide of tin, an oxide of niobium or an oxide of titanium. For example, the second anti-reflection layer 520 can be selected from magnesium fluoride.
