[0050] Some implementation manners of this application will be described in detail. Without conflict, the following implementation manners and the features in the implementation manners can be combined with each other.

[0051] Embodiment

[0052] Figures 1 - 3 A vehicle 100 according to an embodiment of the present application is shown.

[0053] The vehicle 100 can be, for example, a fuel vehicle (such as a gasoline vehicle, a diesel vehicle, etc.), an electric vehicle (such as a pure electric vehicle, a fuel cell vehicle) or a hybrid vehicle.

[0054] The vehicle 100 has a window glass assembly 10 for lighting and separating the interior and exterior spaces of the vehicle 100. Among them, the window glass assembly 10 can be the front windshield of the vehicle 100, the rear windshield 10a, the side window glass, etc.

[0055] The interior space of the vehicle 100 is provided with a display screen assembly 20 for displaying images. For example Figure 2 and Figure 3 As shown in, the display screen assembly 20 is the ceiling screen 20a of the vehicle 100.

[0056] In other embodiments, the display screen assembly 20 may also be the instrument screen, the central control screen, the seat back screen or other in-vehicle display screens of the vehicle 100.

[0057] In this embodiment, the display screen assembly 20 and the window glass assembly 10 form a vehicle anti-peeping structure 110, which can realize the privacy protection inside the vehicle 100, and will be exemplarily introduced below.

[0058] Figures 4 - 6 The vehicle anti-peeping structure 110 of this embodiment is shown. The vehicle anti-peeping structure 110 includes a display screen assembly 20 and a window glass assembly 10. Exemplarily, the window glass assembly 10 is the rear windshield 10a of the vehicle 100, and the display screen assembly 20 is the ceiling screen 20a of the vehicle 100.

[0059] For a vehicle with a conventional window glass and an in-vehicle screen, the light emitted by the in-vehicle display screen is relatively easily observed by people outside the vehicle, resulting in the privacy leakage of the in-vehicle display screen. Especially in scenes with relatively dim natural light (such as rainy days, nights or in basements with poor lighting), the actively emitting display screen will be more easily observed from outside the vehicle.

[0060] In view of this, as Figures 7 - 9 , the vehicle anti-peeping structure 110 provided in this embodiment has its display screen assembly 20 configured to be able to emit P-type linearly polarized light. At the same time, its window glass assembly 10 includes a window glass 11 and an S-type linearly polarized light film 12 provided on the window glass 11.

[0061] Figure 7 This is an exploded view of the display screen assembly 20 in this embodiment.

[0062] See Figure 7 , the display screen assembly 20 in this embodiment includes an OLED display screen 21 and a P-type linearly polarized light film 22. The P-type linearly polarized light film 22 is attached to the light-emitting side of the OLED display screen 21 to convert the light emitted by the OLED display screen 21 into P-type linearly polarized light. For example, the P-type linearly polarized light film 22 is attached to the outer surface of the OLED display screen 21. Optionally, the OLED display screen 21 can also be replaced with other display screens that can emit unpolarized light.

[0063] In other embodiments, the display screen assembly 20 can also be an LCD display screen that can emit P-type linearly polarized light.

[0064] Figure 8 This is an exploded view of the window glass assembly 10 in this embodiment, Figure 9 This is a schematic diagram of the laminated structure of the window glass assembly 10.

[0065] See Figure 8 and Figure 9, the window glass 11 includes an inner layer glass 11a and an outer layer glass 11b. The S-type linearly polarized light film 12 is sandwiched between the inner layer glass 11a and the outer layer glass 11b. The inner layer glass 11a and the S-type linearly polarized light film 12 are adhered together through an inner adhesive layer 11c, and the outer layer glass 11b and the S-type linearly polarized light film 12 are adhered together through an outer adhesive layer 11d. Optionally, both the inner adhesive layer 11c and the outer adhesive layer 11d are made of PVB film. The PVB film is made of a light-transmitting material, and its influence on the permeability of the window glass 11 is very small.

[0066] Optionally, the window glass assembly 10 further includes a black edge layer 13. The black edge layer 13 is provided on the inner surface of the inner layer glass 11a and is in a ring shape extending along the outer periphery of the inner layer glass 11a. The inside of the black edge layer 13 is a through hole K1 without material, which does not affect the permeability of the window glass assembly 10. By providing the black edge layer 13, the outer periphery of the window glass assembly 10 can look black in a circle, giving the window glass assembly 10 a better appearance effect.

[0067] See Figure 10 , in this embodiment, the P-type linearly polarized light L1 emitted by the display screen assembly 20 cannot pass through the window glass assembly 10 with the S-type linearly polarized light film 12, so that the personnel outside the vehicle 100 cannot observe the picture of the display screen assembly 20. And the ambient light L2 outside the vehicle 100 is unpolarized light, and a part of the light polarized in the S direction among them can pass through the window glass assembly 10 with the S-type linearly polarized light film 12, so that the field of view permeability of the vehicle 100 can be maintained.

[0068] At the same time, the window glass assembly 10 in this embodiment is provided with an S-type linearly polarized light film 12, and the vibration direction of the S-type linearly polarized light film 12 and the light emitted by the display screen assembly 20 are perpendicular or nearly perpendicular to each other. In this embodiment, the included angle θ between the two can take a value of 85-90°. According to Malus' law, the transmittance = cos2θ. When θ = 85-90°, the transmittance is close to 1 or equal to 1, and the field of view permeability of the window glass assembly 10 can be maintained.

[0069] In addition, the window glass assembly 10 uses an S-type linear polarized light film 12, and the light incident from the outside of the vehicle 100 is converted into S-type linear polarized light after passing through the S-type linear polarized light film 12. According to the Fresnel equation, at medium and high incident angles (45-90°), the S light reflectivity > natural light reflectivity > P light reflectivity, and the difference is significant; at medium and low incident angles (0-45°), the reflectivity of S-type linear polarized light ≈ natural light reflectivity ≈ P-type linear polarized light reflectivity, and there is no significant difference between the three. When it is necessary to achieve selective light transmission at a commonly used viewing angle near the incident angle = 0° with high transmittance, the transmittance of the window glass assembly 10 of this embodiment is about 96%, which is close to or the same as the transmittance of ordinary tinted privacy window glass. When the incident angle is at the commonly used pitch viewing angle near 45°, the transmittance of the vehicle window glass assembly 10 is about 91%, which is slightly different from the 95% transmittance of ordinary tinted privacy window glass; when the incident angle is at an elevation angle of 75°, the transmittance of the vehicle window glass assembly 10 is about 60%, which is quite different from the 75% transmittance of ordinary tinted privacy window glass. The selective light-blocking effect of low transmittance at medium and high incident angles can reduce the intensity of incident sunlight.

[0070] In addition, in this embodiment, the P-type linear polarized light emitted by the display screen assembly 20 in the vehicle 100 is compatible with P-type polarized glasses. Common polarized glasses are P-type, so the driver and passengers wearing P-type polarized glasses in the vehicle 100 can watch the screen of the display screen assembly 20 without taking off the glasses.

[0071] Figure 11 Another embodiment of a vehicle window glass assembly 30 is shown.

[0072] See also Figure 11 The vehicle window glass assembly 30 includes an inner layer of glass 11a, an intermediate layer 14 and an outer layer of glass 11b, wherein the intermediate layer 14 is sandwiched between the inner layer of glass 11a and the outer layer of glass 11b. The intermediate layer 14 includes an S-type linear polarizing film 14a and a splicing layer 14b, wherein the splicing layer 14b is connected to the outer periphery of the S-type linear polarizing film 14a to form an annular black border area.

[0073] Optionally, the inner glass 11a is bonded to the middle layer 14 via an inner bonding layer 11c, and the outer glass 11b is bonded to the middle layer 14 via an outer bonding layer 11d. The inner bonding layer 11c and the outer bonding layer 11d are both transparent PVB films, and the splicing layer 14b is made of opaque PVB material.

[0074] Figure 11The shown window glass assembly 30 forms a black edge area through the splicing layer 14b that is on the same layer as the S-type linearly polarized light film 14a, which can reduce the usage amount of the S-type linearly polarized light film 14a, reduce costs, and the splicing layer 14b located on the outer periphery of the S-type linearly polarized light film 14a also uses PVB material, which can be more reliably bonded to the inner bonding layer 11c and the outer bonding layer 11d, facilitating the improvement of the integrity of the window glass assembly 30.

[0075] In summary, for the vehicle anti-peeping structure 110 in this embodiment, through the S-type linearly polarized light films 12, 14a of the window glass assemblies 10, 30 and the display screen assembly 20 that emits P-type linearly polarized light, it is possible to see the inside of the vehicle 100 from the outside of the vehicle 100 but hardly see the picture of the display screen assembly 20 inside the vehicle 100, and it is possible to see the outside of the vehicle 100 clearly and also view the picture of the display screen assembly 20 clearly from the inside of the vehicle 100. That is, it is possible to selectively and privately partition the picture of the display screen assembly 20 while maintaining a clear view. At the same time, the vehicle anti-peeping structure 110 can also reflect a larger proportion of the medium- and high-angle light incident from the external environment of the vehicle 100 to reduce the entry of medium- and high-angle ambient light into the vehicle 100.

[0076] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the above preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
