Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to glass, a vehicle window, a vehicle and a control method. Background Art

[0002] At present, the car skylight glass mainly improves the display effect by adjusting the background transmittance through the dimming film. However, these existing technologies have obvious defects. Under the background of strong light spots, the light spots generated by the light spots cannot be solved by adjusting the transmittance through the dimming film alone. The existence of bright light spots seriously interferes with the picture effect of the in-car display, greatly weakens the viewing experience, and cannot meet people's demand for high-quality car displays. Summary of the invention

[0003] The object of the present invention is to provide a glass, a vehicle window, a vehicle and a control method, aiming to solve the problem that the glass of the existing automobile may be affected by other light sources.

[0004] In order to achieve the above object, the present invention adopts the following technical scheme:

[0005] In a first aspect, the present invention provides a glass comprising a main body and an atomizing element, wherein the atomizing element is connected to the main body and is suitable for switching to an atomizing state to change the haze of the glass.

[0006] In the atomized state of the glass provided in the embodiment of the present application, the atomizing element inside the glass changes the refractive index of the glass, and the originally uniform medium becomes non-uniform. When light is irradiated to the atomized glass, the light is scattered in the non-uniform medium.

[0007] This scattering effect causes the light to no longer propagate in a straight line along the original direction, but to diverge in all directions, thereby dispersing the energy of the light, reducing the concentration of the light at a certain point, and thus avoiding the generation of light spots.

[0008] When light passes through atomized glass, its propagation direction and path become more complex and irregular, and no longer propagate in a straight line like in ordinary glass. This change in the light path makes it difficult for light to gather at a specific position to form a light spot, thus effectively solving the light spot problem.

[0009] On the other hand, when the atomizer switches to the atomized state, the haze of the glass increases. When looking inside the glass from the outside, the outline and details of the object will be blurred, which can effectively block the outside view from penetrating the glass. In this way, users can flexibly adjust the state of the glass according to their needs.

[0010] In some embodiments, the atomizing element has an atomized state and a transparent state. When the atomizing element is in the atomized state, the haze of the glass is a first haze; when the atomizing element is in the transparent state, the haze of the glass is a second haze, and the second haze is smaller than the first haze.

[0063] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0064] In order to improve the comfort of the driver and passengers when using the vehicle 1, the automotive projection technology can project high-definition images onto suitable surfaces in the vehicle, such as the roof, windows, etc.

[0065] Passengers can enjoy a large-screen viewing experience in the car, with a screen size far exceeding that of traditional car displays, creating an atmosphere similar to that of a private cinema. Whether watching movies, TV series, or playing video entertainment programs during a long journey, passengers can be immersed in it and effectively relieve travel fatigue.

[0066] However, the commonly used method at present is to adjust the background transmittance through the atomizer 30 to optimize the in-vehicle display environment. This method can indeed reduce the background brightness to a certain extent, providing certain convenience for in-vehicle viewing or information display. However, when faced with a strong light spot background, its disadvantages will be significantly exposed.

[0067] In order to solve the above technical problems, see Figure 1 , the present application provides a vehicle 1, which includes a vehicle window.

[0068] Exemplarily, the vehicle window is the front windshield of the vehicle 1 , which can project the required images to the driver or the front passenger.

[0069] In another exemplary embodiment, the vehicle window is a sunroof glass 2 of the vehicle 1, which can provide passengers with a wider projection viewing field. Both front and rear passengers can obtain a better viewing angle and can comfortably watch the projection content without excessively tilting their heads or adjusting their sitting posture.

[0070] For the sake of convenience of explanation, the present application takes a vehicle window disposed on the top of the vehicle, which is a sunroof glass 2 of the vehicle 1, as an exemplary illustration.

[0071] In some embodiments, see Figure 2 The vehicle in the present application further includes a projection device, which is arranged opposite to the vehicle window, with the projection end of the projection device facing the vehicle window, and the vehicle window is used to display the projection content of the projection device.

[0072] See also Figure 3 The projection device comprises a projection element 80 adapted to transmit a projection image, Figure 3 The projection display area 81 of the projection element 80 on the sunroof glass 2 in the present application is shown.

[0073] It can be seen that the size of the projection display area 81 is smaller than the background being projected. For example, the background is the skylight glass 2.

[0074] Therefore, the projection element 80 can utilize the larger area of ​​the sunroof glass 2 to provide passengers with a very shocking visual experience.

[0075] At the same time, due to the limited space inside the vehicle 1, traditional in-vehicle display devices often need to occupy a certain space for installation, such as above the center console or behind the headrest, which may have a certain impact on the storage space or passenger activity space inside the vehicle. However, using the sunroof glass 2 for projection makes full use of the original sunroof space without occupying other additional space inside the vehicle.

[0076] In some embodiments, see Figure 2 The glass in the present application includes a main body and an atomizing element 30, the atomizing element 30 is connected to the main body, and the atomizing element 30 is suitable for switching to an atomizing state to change the haze of the glass.

[0077] In the present application, the haze of the glass can be changed accordingly by switching the haze of the atomizer 30. When the haze of the atomizer 30 is adjusted, it is just like directly operating the haze of the glass. There is a close correlation and equivalence between the two. Adjusting the haze of the atomizer 30 can ultimately change the haze of the glass.

[0078] It can be understood that the haze of the atomizing element 30 is equivalent to the haze of glass.

[0079] In the transparent state, the atomizing element 30 has a high transmittance to light, which can ensure that there is enough natural light in the car, so that passengers can clearly see the scene outside the car. In the atomized state, the haze of the glass increases significantly, which can effectively scatter light.

[0080] When the driver and passengers actually use the projection, since the glass of the vehicle 1 allows external light sources to penetrate, for example, on a sunny day, when the direction of the car's travel is at a certain angle to the sunlight, the strong light spots formed by the sunlight passing through the window will produce light spots in the car.

[0081] Due to its high brightness, this light spot will seriously interfere with the image display effect observed in the car. The high brightness of the light spot area forms a sharp contrast with the surrounding normal display area, resulting in an imbalance in the overall contrast of the picture. The visual focus of the driver and passengers is easily affected by the light spot, reducing the experience during use.

[0082] The light spots formed may cover some key details of the picture, making the picture blurry or missing some content. Moreover, since the position and brightness of the light spots may change with the movement of the vehicle 1 and the change of light angle, this unstable interference factor further aggravates the degree of damage to the display picture in the car, making it impossible for the driver and passengers to obtain a continuous and clear visual experience.

[0083] In the present application, by switching the working state of the atomizing element 30 , the glass can be adapted to the needs of the driver, and the projection effect inside the car can be prevented from being affected by the outside world during projection.

[0084] For example, when the external light is strong, such as on a sunny day, the atomizer 30 switches to the atomized state. At this time, the strong light from the outside irradiates the atomizer 30, which will be scattered by its atomized surface and cannot directly pass through the atomizer 30 to irradiate the projection element 80, thereby avoiding the strong light from forming a light spot or reflection on the projection element 80, which affects the projection effect.

[0085] At the same time, the atomized atomizing element 30 can also reduce the overall transmittance of external light, making the light environment inside the vehicle relatively darker, providing a relatively dark background for the projection element 80, enhancing the contrast between the projection image and the background, and making the projection content clearer and more discernible.

[0086] On the contrary, when the external light is weak, such as at night or on a cloudy day, the atomizer 30 switches to a transparent state, so that sufficient light can enter the car, so that the passengers can maintain a good view inside the car while watching the projected content, and the projected image will not appear too dark due to excessive shielding of the atomizer 30.

[0087] Among them, the working state switching of the atomizer 30 in the present application can be manually switched or automatically switched, and the present application does not limit this.

[0088] Exemplarily, when the atomizing element 30 is in an atomized state, the haze of the glass is greater than or equal to 50%.

[0089] Exemplarily, when the atomizing element 30 is in an atomized state, the haze of the glass is greater than or equal to 60%.

[0090] Exemplarily, when the atomizing element 30 is in an atomized state, the haze of the glass is greater than or equal to 80%.

[0091] As another example, when the atomizing element 30 is in the atomized state, the haze of the glass is greater than or equal to 90%. Further, when the atomizing element 30 is in the atomized state, the haze of the glass is greater than or equal to 95%.

[0092] Through the above-mentioned configuration, the glass of the present application can meet the different requirements of drivers and passengers for haze, thereby improving practicality and user experience.

[0093] Under strong external light such as strong sunlight, the light will be scattered multiple times on the atomized surface of the atomizer 30. This scattering causes the originally concentrated light to be dispersed into weak light in all directions, thereby effectively preventing the strong light from forming a light spot on the projection element 80.

[0094] When the atomizing element 30 is in an atomized state and the haze is greater than or equal to 95%, that is, the haze of the glass is greater than 95%, the scattering effect of the glass on light reaches an extremely high level.

[0095] When facing various intensities of light from the outside, whether it is strong direct sunlight from the top of the vehicle or strong light at night such as street lamps, headlights of opposite vehicles, etc., almost all incident light will be evenly scattered. This makes it impossible for light to form concentrated spots or strong reflected light to enter the car, thus providing the most reliable protection for the projection effect inside the car.

[0096] In addition, when the atomizing element 30 is in an atomized state, the privacy of the information inside the vehicle can be guaranteed, and the sight of people outside the vehicle can be effectively blocked to prevent them from peeking at the displayed information inside the vehicle.

[0097] In some embodiments, the atomizing element 30 has an atomized state and a transparent state. Based on the adjustment of the haze by the atomizing element 30, the haze of the glass is also adjusted accordingly. When the atomizing element 30 is in the atomized state, the haze of the glass is a first haze; when the atomizing element 30 is in the transparent state, the haze of the glass is a second haze, and the second haze is smaller than the first haze.

[0098] When the atomizer 30 is in the atomized state and has the first haze, the haze of the glass is the first haze, which can strongly scatter and block light. When the atomizer 30 switches to the transparent state, its haze is the second haze and is less than the first haze. At this time, the atomizer 30 has little obstruction to light, which can ensure that the vehicle has sufficient natural lighting.

[0099] In this way, the atomizing element 30 can respond according to the real-time change of the external light intensity. This switching function meets the needs of the driver and passengers in various driving and riding scenarios during the use of the vehicle 1.

[0100] Exemplarily, when the atomizing element 30 is in a transparent state, the haze of the glass is less than or equal to 6%, and further, the haze of the glass is less than or equal to 5%.

[0101] As another example, when the atomizing element 30 is in a transparent state, the haze of the glass is less than or equal to 5%, and further, the haze of the glass is less than or equal to 4%.

[0102] In addition, in order to meet the diverse needs of drivers and passengers for light passing through the glass, the atomizer 30 also has at least one semi-atomized state. When the atomizer 30 is in the semi-atomized state, the haze of the atomizer 30 is a third haze, which is greater than the second haze and less than the first haze. Correspondingly, when the atomizer 30 is in the semi-atomized state, the haze of the glass is a third haze, which is greater than the second haze and less than the first haze.

[0103] For example, in some cases with complex lighting conditions, such as early morning or evening, when the sunlight intensity is moderate but the angle is low, you may need a certain amount of lighting while avoiding glare that affects projection viewing. At this time, the semi-fog state can provide a compromise solution. The driver and passengers can choose the appropriate third fog according to their actual feelings, so that the car can maintain a certain brightness, allowing the driver and passengers to feel the external environment, and ensure that the projection picture is clear and discernible without being disturbed by excessive light.

[0104] And from the perspective of visual comfort, the existence of the third haze can effectively avoid the discomfort to the eyes caused by sudden changes in light.

[0105] Compared with the two extreme states of transparency and complete atomization, the semi-atomized state can achieve a smooth transition of light. When the external light gradually changes, the atomizer 30 can gradually adjust to the appropriate semi-atomized state, so that the light environment in the car is always kept in a relatively stable and comfortable range. This is especially important for people who drive for a long time, reducing eye fatigue and discomfort, and improving the overall driving experience.

[0106] In some embodiments, the atomizing element 30 is suitable for changing the haze of the atomizing element 30 by adjusting the magnitude of the input current, thereby changing the haze of the glass.

[0107] Exemplarily, when the current is 0, that is, the circuit is disconnected, the atomizer 30 is in an atomized state, and as the current increases, the atomizer 30 tends to transition to a transparent state. Alternatively, when the current is 0, that is, the circuit is disconnected, the atomizer 30 is in a transparent state, and as the current increases, the atomizer 30 tends to transition to an atomized state.

[0108] The driver and passenger can control the working state of the atomizer 30 through simple operations such as pressing a button or sliding on a touch screen to easily switch the light environment.

[0109] For example, when driving, the driver may need a clear view to observe the road conditions, and the atomizer 30 can be switched to a transparent state; when the passenger is watching the projection or needs a relatively private space, the atomizer 30 can be adjusted to an atomized state. The semi-atomized state plays a role in some transitional scenes or special needs, such as ensuring a certain amount of lighting while avoiding strong light interference in an environment with moderate light.

[0110] On the one hand, the color of the dimming film 30 is black or grayish black, and it has a strong light absorption ability. When light enters the dimming film 30, whether it is strong light from the outside such as sunlight or stray light that may exist in the car, the light absorption layer can absorb a large amount of it.

[0111] In addition, when the dimming film 30 is in the atomized state, the dimming film 30 scatters the light, and the dimming film 30 can absorb some unnecessary light in the scattering process, further optimizing the light environment. For example, when watching a movie in the car, the dimming film 30 allows the movie picture to be clearly displayed against the atomized background, enhancing the layering and three-dimensional sense of the picture.

[0112] On the other hand, the dimming film 30 can adjust the light transmittance and scattering degree according to actual needs. When the dimming film 30 is in an atomized state, light will be strongly scattered when passing through the dimming film 30, thereby effectively blocking the direct transmission of external strong light, avoiding the formation of light spots or reflections on the projection element 80, and protecting the integrity of the projection image.

[0113] In some embodiments, the color of the dimming film 30 is black or grayish black.

[0114] The black or grayish black dimming film 30 mainly absorbs the full wave of sunlight through the optical properties and microstructure of special materials. It can interact with light of different wavelengths to achieve a wide range of absorption from ultraviolet to infrared. At the microscopic level, the nanostructure triggers the transition of electron energy levels, the molecular vibration absorbs infrared energy, and the electron cloud in the molecular structure interacts with visible light photons to convert light energy into other forms, thereby reducing light transmission.

[0115] This color presentation is due to the uniform absorption of all colors of visible light, which avoids the color distortion of the projected image caused by selective light absorption. At the same time, the low reflectivity and effective control of scattered light reduce the interference of reflected and scattered light on the projected light, ensuring the clarity of the picture.

[0116] In terms of the functional coordination of the dimming film 30, in the atomized state, the black or grayish black color continuously absorbs light, reduces the intensity of background light, and controls the impact of scattered light on the projected image; when switching states, the light absorption and reflection ratio is adjusted according to the change in transparency. Cooperating with the projection device, it creates a low-interference environment for it and ensures the quality of the projection light.

[0117] The dimming film 30 can complement other optical layers to jointly improve light utilization, reduce the impact of reflected light, achieve the goal of absorbing the full wave of sunlight, avoid filtering affecting the projection color, and reduce the intensity of background light, providing a high-quality projection viewing experience in the car.

[0118] In some embodiments, the a value of the color of the dimming film is greater than or equal to -3 and less than or equal to 3.

[0119] Exemplarily, the a value of the color of the dimming film 30 is greater than or equal to −2 and less than or equal to 2.

[0120] In some embodiments, the b value of the color of the dimming film 30 is greater than or equal to −3 and less than or equal to 3.

[0121] In another exemplary embodiment, the b value of the color of the dimming film 30 is greater than or equal to −2 and less than or equal to 2.

[0122] Among them, a and b usually refer to two chromaticity coordinates in the CIELAB color space. The CIELAB color space is a color representation method based on human visual perception. Among them, L represents lightness, ranging from 0 black to 100 white.

[0123] a and b are chromaticity coordinates, a represents the position on the red-green axis, positive values ​​represent the red direction, and negative values ​​represent the green direction; b represents the position on the yellow-blue axis, positive values ​​represent the yellow direction, and negative values ​​represent the blue direction.

[0124] When the interval is -2≤b≤2 and -2≤a≤2, it means that the color deviates less in the red-green and yellow-blue directions, and the overall color tends to be close to neutral colors, that is, black, gray or white.

[0125] Neutral or grayish black dimming film 30 satisfies -2≤b≤2 and -2≤a≤2 and can effectively absorb the full wave of sunlight, because this color will not produce strong reflection or transmission of light of specific wavelengths such as red, green, yellow, blue, etc., and its absorption of light is relatively uniform.

[0126] Whether it is ultraviolet light, visible light or infrared light in sunlight, it can be well absorbed. For example, in the daytime with strong sunlight, this color of the dimming film 30 can reduce the amount of sunlight transmitted, prevent the temperature in the car from rising sharply due to excessive light entering, and also create a relatively dark background environment for projection display.

[0127] And when a and b are in this range, since the color is close to neutral, no specific color components in the projection light will be selectively filtered.

[0128] Due to the absorption characteristics of this color to light, it can effectively reduce the intensity of background light. Inside the vehicle 1, the background light mainly comes from the light from the outside that passes through the window. When the dimming film 30 is a neutral color or gray-black color that meets the interval requirements, it can block most of the outside light from entering the vehicle, thereby reducing the intensity of the background light inside the vehicle.

[0129] Lower background light intensity can improve the contrast of the projected image, making the bright parts brighter and the dark parts darker, so that passengers can see the details of the projected content more clearly and improve the visual experience. At the same time, lower background light intensity also helps to create a comfortable lighting environment in the car and reduce glare stimulation to the passengers' eyes.

[0130] Exemplarily, the atomizing element 30 includes a polymer dispersed liquid crystal dimming film 30 having a color dispersion effect.

[0131] Exemplarily, the dimming film 30 includes a liquid crystal dimming film 30 doped with a dichroic dye having a color dispersion effect.

[0132] Exemplarily, the dimming film 30 includes a liquid crystal dimming film 30 doped with a dichroic dye having a light absorbing effect.

[0133] When the dimming film 30 includes a liquid crystal dimming film 30 of a dichroic dye having a scattering effect, the dye can scatter light in the atomized state. When looking from the outside to the inside of the glass, the scene inside becomes blurred due to the scattering of light.

[0134] When a light source is irradiated on the glass, ordinary glass is prone to produce light spots and reflection phenomena. Due to the scattering effect, the dimming film 30 can disperse the light and avoid the light spots formed on the surface or inside of the glass.

[0135] In addition, the liquid crystal dimming film 30 doped with a dichroic dye having a light-absorbing effect can absorb part of the light. In scenarios where it is necessary to reduce the amount of light entering a room or a car, such as when the sun is strong, the dimming film 30 can reduce the intensity of the light. In some display applications, the light absorption effect can reduce the interference of ambient light on the displayed content and improve the contrast and color reproduction of the projected image.

[0136] In some embodiments, the glass also includes a light absorbing layer disposed between the outer glass 10 and the light emitting component 50, the color of the light absorbing layer is black or grayish black, and when the atomizing component 30 is in an atomized state, the visible light transmittance corresponding to the side of the light emitting component 50 facing the outer glass 10 is less than 35%.

[0137] Exemplarily, the light-absorbing layer is at least one of the second adhesive layer 60, the dimming film 30, the first adhesive layer 20, and the outer glass 10, and at least one of the above parts has a black light-absorbing effect, so that when the atomizing element 30 is in an atomized state, the visible light transmittance corresponding to the side of the light-emitting element 50 facing the outer glass 10 is less than 35%.

[0138] Furthermore, when the atomizing element 30 is in the atomized state, the visible light transmittance of the side of the luminous element 50 facing the outer glass 10 is less than 30%, which can effectively reduce the external light entering the car as background light. At the same time, due to the reduction of interference from external light, the color components in the projected light can be presented more purely.

[0139] The visible light transmittance is less than 30%, which makes it difficult to see the projection content and other situations inside the vehicle from outside the vehicle. This effectively protects the privacy of passengers inside the vehicle when the vehicle 1 is stationary or moving.

[0140] In addition, this setting enables the in-car projection system to better adapt to various usage scenarios. Whether in a well-lit outdoor environment or in a dark underground parking lot, the in-car light conditions can be adjusted by limiting the visible light transmittance to meet the needs of projection display.

[0141] In some embodiments, see Figure 2 The main body of the present application includes an outer layer of glass 10 and an inner layer of glass 70 which are spaced apart from each other, and the atomizing element 30 is disposed between the outer layer of glass 10 and the inner layer of glass 70 .

[0142] For example, the outer layer of glass 10 and the inner layer of glass 70 may be a combination of laminated glass to improve the overall safety of the glass.

[0143] When flat glass is used for the inner layer of glass 70 and the outer layer of glass 10, the glass opening in the present application can be used on the skylight of the vehicle 1 or the flat window of a building. The inner layer of glass 70 and the outer layer of glass 10 can also be curved glass. When curved glass is used, curved functional laminated glass suitable for the vehicle 1 can be obtained, which is mostly used for the side windows of the vehicle 1 and can also be used for windows in other positions of the vehicle 1.

[0144] In some embodiments, the glass in the present application has a light-transmitting area, and the glass further includes a first shielding layer 11 and a second shielding layer 71 .

[0145] It should be noted that the projection display area 81 falls into the above-mentioned light-transmitting area.

[0146] Exemplarily, the first shielding layer 11 is disposed between the outer glass 10 and the atomizing element 30 , and the first shielding layer 11 is provided with a first avoidance opening suitable for avoiding the light-transmitting area so that the light beam can penetrate the glass.

[0147] In another exemplary embodiment, the second shielding layer 71 is disposed on the surface of the inner glass 70 facing away from the atomizing element 30 , and the second shielding layer 71 is provided with a second avoidance opening suitable for avoiding the light-transmitting area so that the light beam can penetrate the glass.

[0148] It should be noted that only one of the first shielding layer 11 and the second shielding layer 71 may be provided, or both may be provided, and this is not limited in the present application.

[0149] The first shielding layer 11 and the second shielding layer 11 are both opaque, and the projection display area 81 eventually falls into the second avoidance opening to form a second perspective area.

[0150] The boundaries of the dimming film 30 may produce obvious visual boundaries due to refraction, reflection of light or differences in the materials themselves. However, with the first shielding layer 11 and the second shielding layer 71, these boundaries are shielded behind the shielding layers, and people can only see the perspective area surrounded by the shielding layers in the transparent area, thereby reducing the possibility of producing obvious boundaries. When light passes through the perspective area, because there is no other messy boundary interference, it feels like a natural transparent and display area without obvious division, thereby improving the appearance effect.

[0151] In some embodiments, various components of the glass in the present application may be bonded by an adhesive layer.

[0152] Exemplarily, the glass includes a first adhesive layer 20 , which is disposed on a surface of the atomizing element 30 facing the first shielding layer 11 , and the atomizing element 30 is suitable for being connected to the first shielding layer 11 through the first adhesive layer 20 .

[0153] Illustratively, the material of the adhesive layer includes adhesive layer materials commonly used in the automotive industry such as PVB, EVA, SPD, etc., which can improve the safety performance of the entire device.

[0154] Furthermore, the inner glass 70 is a kind of clear glass or ultra-clear glass.

[0155] In some embodiments, correspondingly, the visible light diffuse reflectance Rs of the surface of the inner glass 70 satisfies: 7%≤Rs≤21%. Further, the visible light diffuse reflectance Rs of the surface of the inner glass 70 satisfies: 6%≤Rs≤20%.

[0156] When the visible light diffuse reflectance of the surface of the inner glass 70 is lower than 6%, the image intensity is low; when the visible light diffuse reflectance of the surface of the inner glass 70 is higher than 20%, the image projected by the glass will appear whitish, affecting the appearance.

[0157] In some embodiments, the glass in the present application further includes a luminous film 50 , and the luminous film 50 is located on a side of the dimming film 30 that is away from the projection device.

[0158] Specifically, the dimming film 30 and the luminous film 50 are connected via the third adhesive layer 40 , and the luminous film 50 and the outer glass 10 are connected via the second adhesive layer 60 .

[0159] In some embodiments, the glass further includes a light emitting member 50 , and the light emitting member 50 is disposed between the inner glass 70 and the atomizing member 30 .

[0160] Exemplarily, the light emitting element 50 includes a light emitting film 50 with a light diffusion effect. In this way, when the external environment is not particularly bright, high-definition display can be achieved without turning on the atomizing element 30, thereby ensuring that the transparent skylight vision requirement can still be maintained in the non-projection area.

[0161] When the light from the projection element 80 is projected onto the light-emitting film 50 with a diffuse light-emitting function, the light-emitting film 50 hardly absorbs visible light. In this way, during projection display, the light energy in the picture can be kept at the strongest state and will not be lost due to absorption by the light-emitting film 50. Thus, a high-definition projection display effect is achieved.

[0162] Correspondingly, the glass further includes a second adhesive layer 60 , which is disposed between the atomizing element 30 and the light-emitting element 50 , and the atomizing element 30 is suitable for being connected to the light-emitting element 50 through the second adhesive layer 60 .

[0163] In some embodiments, the glass further includes a third adhesive layer 40 , which is disposed on the surface of the light emitting element 50 facing the inner glass 70 , and the light emitting element 50 is adapted to be connected to the inner glass 70 through the third adhesive layer 40 .

[0164] In some embodiments, the diffuse reflectance R0 of visible light of the light emitting element 50 satisfies: 6%≤R0≤19%. Specifically, the diffuse reflectance R0 of visible light of the light emitting element 50 satisfies: 5%≤R0≤18%.

[0165] When the diffuse reflectivity is too low, such as less than 5%, most of the light will propagate in a predetermined direction, and less light will be scattered and reflected, which will result in reduced image intensity.

[0166] When the diffuse reflectivity is too high, exceeding 18%, the appearance of the glass will be whitish and unsightly. Too much light is scattered disorderly on the surface and inside of the atomizing element 30, and the glass and window glass viewed from outside the vehicle are like being covered with a layer of white mist, which not only destroys the original texture and color of the vehicle 1, but also may interfere with the light environment inside the vehicle.

[0167] When the visible light diffuse reflectivity of the atomizer 30 is in this range, it can prevent the image intensity from being too low and prevent the glass appearance from turning white due to excessive diffuse reflection, thereby achieving an ideal balance while ensuring the quality of the projected image and maintaining the beautiful appearance of the skylight.

[0168] In some embodiments, the glass further includes a first portion, the first portion includes a light emitting member 50, a third adhesive layer 40 and an inner glass layer 70, and a visible light absorption rate of the first portion is less than or equal to 6%.

[0169] When the visible light absorption rate of this part is less than or equal to 5%, the energy loss of the projection light is very small in the process of propagating from the projection element 80 to the inner glass 70. This means that most of the projection light can pass smoothly, thereby ensuring that the projection image has sufficient brightness.

[0170] Low absorption helps maintain the original color characteristics of the projected light. Because less light is absorbed, the various color components in the projected light can reach the viewing area in the expected proportions, without causing image color distortion due to excessive absorption of some color lights.

[0171] Correspondingly, when the atomizer 30 is in the atomized state, the visible light transmittance of the glass is less than 26%, and further, the visible light transmittance of the glass is less than 25%.

[0172] As another example, when the atomizing element 30 is in a transparent state, the visible light transmittance of the glass is greater than or equal to 0.5%, that is, at this time, the glass at least meets the condition of being able to transmit light.

[0173] Exemplarily, the dimming film 30 in the present application is a diffuse dimming film 30 , and the dimming film 30 is an optical device with a compensation function. The luminescent film 50 in the present application is a diffuse luminescent film 50 .

[0174] In some embodiments, see Figure 4 In the present application, the glass further includes an anti-reflection member 72, which is disposed on the side of the inner layer of glass 70 facing away from the outer layer of glass 10, and the visible light reflectivity of the glass is less than 2%.

[0175] Exemplarily, the anti-reflection element 72 is an anti-reflection film.

[0176] On this basis, the visible light reflectivity of the glass has also been changed.

[0177] Illustratively, the visible light reflectance of the glass is less than 1%.

[0178] In another exemplary embodiment, the visible light reflectivity of the glass is less than 0.5%.

[0179] Lower visible light reflectivity can weaken the specular reflection of the projector and light source, further improve the display effect, and is more conducive to the optical path arrangement of the projector.

[0180] In addition, the present application provides a control method, and the subject executing the method can be a vehicle controller, or can be various devices / modules in the vehicle controller, such as an integrated circuit or a chip, and the embodiments of the present application do not specifically limit this.

[0181] In addition, the method is applicable to the above-mentioned glass, vehicle window and vehicle 1, to which the present application does not make any limitation.

[0182] In some embodiments, the method comprises:

[0183] When the first preset condition is met, the atomizing element 30 is in an atomizing state.

[0184] When the first preset condition is met and the atomizer 30 is in an atomized state, the interference of strong external light on the projection image can be effectively reduced, and the display effect of the projection can be optimized. At the same time, the atomizer 30 in an atomized state can significantly enhance the privacy protection function. When the vehicle 1 is stationary or moving, it is difficult for outsiders to see the projection content and the activities of the passengers in the vehicle through the atomized atomizer 30.

[0185] In some embodiments, the first preset condition includes obtaining a haze input value, and the haze input value is within the haze range of the glass in a hazed state, that is, the haze input value is within the haze range of the atomizing element 30 in a hazed state.

[0186] When the received haze input value is within the haze range of the glass in the haze state, it means that the haze degree set by the user is a reasonable requirement that the glass can achieve. For example, if the haze input value is 70%, and the haze range of the glass in the haze state is 50%-90%, then this setting value is valid, and the control system of the vehicle 1 will adjust the glass according to this input value, that is, adjust the haze state of the atomizer 30 so that the glass reaches the corresponding 70% haze state. This setting ensures that the user's expectations for the degree of glass haze can be achieved within the performance allowable range of the glass, thereby effectively controlling functions such as the in-vehicle light environment and the degree of privacy protection.

[0187] In some embodiments, the first preset condition includes obtaining an illuminance value of the ambient light, where the illuminance value is greater than a first preset threshold.

[0188] Exemplarily, the first preset threshold is greater than or equal to 400 lux and less than or equal to 60,000 lux.

[0189] Specifically, the first preset threshold is greater than or equal to 500 lux and less than or equal to 50,000 lux.

[0190] When the obtained ambient light illuminance value is greater than the first preset threshold value, such as between 500 lux and 50000 lux, it indicates that the external light is strong. In this case, making the atomizing element 30 in an atomized state can effectively improve the projection display effect.

[0191] Exemplarily, the vehicle 1 further includes an optical sensor adapted to sense ambient light intensity. The optical sensor may convert a received optical signal into an electrical signal, and the system controls the working state of the atomizer 30 according to the electrical signal.

[0192] It should be noted that the execution subject of the above system may be the vehicle 1, or may be the control system corresponding to the vehicle 1 system or a separate glass, and this application does not limit this.

[0193] In some embodiments, the first preset condition further includes turning on the projection device.

[0194] The projection device is turned on to indicate that the passengers in the vehicle have the demand to watch the projection content. In this case, making the atomizing element 30 in an atomized state can create a more suitable environment for projection.

[0195] For example, when the vehicle 1 is driving, if a passenger wants to watch a movie, turning on the projection device and atomizing the atomizer 30 can reduce the interference of external light such as sunlight or street lights on the projection picture and enhance the contrast and visibility of the projection picture.

[0196] In some embodiments, the method further includes: when a second preset condition is met, placing the atomizing element 30 in a transparent state.

[0197] In some embodiments, the method further includes: when a third preset condition is met, placing the atomizing element 30 in a semi-atomized state.

[0198] The following is an exemplary description of one application of the projection element 80 in the present application in the vehicle 1 .

[0199] When the projector is turned on, within 10 seconds of startup, the state of the display glass will be adjusted in the following two situations.

[0200] First, vehicle 1 is provided with a dimming interface, and the driver and passenger input a dimming preset value, and the dimming controller will adjust the state of the display skylight glass according to the dimming preset value, so that it is adjusted to a fogged state, a transparent state, or a semi-fogged state between fogged and transparent.

[0201] Furthermore, the dimming preset value can be two clear levels of fog and transparency, or multiple states in between such as semi-fog, very fog, slight fog, etc., or represented by a numerical percentage, such as 0%, 10%, 20%...100%, etc.

[0202] Secondly, if the dimming preset value is not input in the dimming interface during this period, the illuminance value of the light sensor will be determined. When the illuminance is higher than the preset value L, the dimming controller will automatically adjust the display skylight glass to a fogged state; and when the illuminance value is lower than the preset value L, the dimming controller will maintain the current state without making any adjustments.

[0203] Exemplarily, the preset illumination value L can be manually set to any value between 500-50000 lux, and the default value can be adjusted to 5000 lux.

[0204] As another example, when the projection element 80 is turned off, the dimming controller can also execute a holding state to meet other requirements of the driver and passengers on the vehicle 1 .

[0205] It should be noted that the effects corresponding to the above control method can be found in the above content. In order to avoid repetition, this application will not go into details.

[0206] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
