[0024] In order to describe in detail the technical content, achieved objectives and effects of the present utility model, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0025] Please refer to Figure 1 and Figure 2 As shown, in one embodiment, it includes a glass assembly 1 and a display component 2; an optical element 11 is provided on the inner side surface of the glass assembly 1, the display component 2 includes a display module 21 located inside the glass assembly 1, the display end 211 of the display module 21 faces the optical element 11, and the display module 21 displays an image 3 in the air outside the glass assembly 1 through the optical element 11. It should be noted that the display end 211 of the display module 21 refers to the part on the display module 21 used to present the image. When the display end 211 faces the optical element 11, it means that the surface of the display end 211 faces the optical element 11 so as to project the image through the optical element 11 and display it in the air outside the glass assembly 1. Among them, the display module 21 preferably adopts a MiniLED display screen. Since the MiniLED display screen can achieve a higher pixel density and finer image performance compared with ordinary LED display screens, it can further ensure the display effect of the image in the air.

[0026] Please refer to Figure 1 As shown, in one embodiment, a light-shielding layer 12 is coated on the inner side surface of the glass assembly 1, the light-shielding layer 12 is provided with a first light-transmitting area 121, and the optical element 11 is located within the first light-transmitting area 121. Among them, the preferred light-shielding layer 12 is formed by printing light-shielding ink on the glass assembly 1. The setting of the light-shielding layer 12 can ensure the clarity and visibility of the image projected by the display module 21, and at the same time reduce the influence of external light on the projected image.

[0027] Please refer to Figure 1 and Figure 2 As shown, in one embodiment, the light-shielding layer 12 is provided with a second light-transmitting area 122, the display component 2 further includes an angle adjustment component 22 and a camera module 23, the movable end of the angle adjustment component 22 is connected to the display module 21, the lens of the camera module 23 faces the second light-transmitting area 122, and the camera module 23 is communicatively connected to the angle adjustment component 22. It should be noted that the movable end of the angle adjustment component 22 refers to the part that can move in the angle adjustment component 22. Therefore, the camera module 23 captures the information of the face direction, and the movable end of the angle adjustment component 22 drives the display module 21 to move according to the face direction information, so that the image projected in the air always faces the face direction, thereby improving the user experience. Specifically, the angle adjustment component 22 includes a driver and a motion bracket. The driver can be a power component directly driving the motion bracket to move provided on the motion bracket, or a power source provided outside the housing 4 and driving the motion bracket to move through a linkage mechanism. The display module 21 is connected to the motion bracket.

[0028] Please refer toFigure 2 As shown, in one embodiment, the distance between the lens of the camera module 23 and the glass assembly 1 is A, and the distance between the display end 211 of the display module 21 and the optical element 11 is B. Among them, preferably, A is 1 mm to 5 mm, and B is 3 mm to 15 mm. A can be 2 mm, 3 mm, 4 mm, etc. It should be noted that the minimum distance between the display end 211 of the display module 21 and the optical element 11 is 3 mm, and the maximum distance is 15 mm.

[0029] Please refer to Figure 1 and Figure 2 As shown, in one embodiment, the light-shielding layer 12 is provided with a third light-transmitting region 123. The display assembly 2 further includes an interaction module 24 for identifying the user's gesture actions. The lens of the interaction module 24 faces the third light-transmitting region 123. The interaction module 24 allows the user to interact in the air through gestures, such as touching the air display screen to realize functions such as screen switching, enhancing the interaction between the user and the system.

[0030] In an alternative embodiment, for the judgment of gestures by the interaction module 24, it can be to capture the position of the user's nails. Since the reflectivity of nails to light is higher than that of skin to light, the recognition accuracy of the interaction module 24 can be improved.

[0031] Please refer to Figure 2 As shown, in one embodiment, the distance between the lens of the interaction module 24 and the glass assembly 1 is C. Among them, preferably, C is 3 mm to 8 mm. Without limitation, C can be 4 mm, 5 mm, 6 mm, 7 mm, etc.

[0032] Please refer to Figure 1 and Figure 2 As shown, in one embodiment, an air-emitting display structure for a vehicle glass further includes a cover body 4 covering the inner side surface of the glass assembly 1. The display assembly 2 and the optical element 11 are located in the inner cavity of the cover body 4. Among them, preferably, the cover body 4 is fixed to the inner side surface of the glass assembly 1, and the display assembly 2 is fixed to the cover body 4. The cover body 4 can protect the display assembly 2 and avoid the influence of light emitted by other devices inside the vehicle, such as indicator lights, on the operation of the display assembly 2.

[0033] Please refer to Figure 1 and Figure 2 As shown, in one embodiment, the optical element 11 is a negative refractive flat lens or a double-layer SMA optical device composed of two layers of mutually orthogonal slit mirror arrays.

[0034] Please refer to Figures 3 to 5As shown in the figure, since the negative refraction flat lens has the same imaging principle as the double-layer SMA optical device. Therefore, the imaging of the double-layer SMA optical device is taken as an example below. In a two-dimensional plane, the light rays emitted from the object point are each reflected once in the double-layer SMA optical device, and the outgoing light rays are emitted in the two-dimensional plane (xy plane) along the direction opposite to the incident light rays (i.e., the incident direction and the outgoing direction of the light rays are parallel and opposite), and several such light rays converge to form an image point. In three-dimensional space, the light rays emitted from the object point are reflected by the double-layer SMA optical device and converge to the symmetric position of the object point with respect to the plane of the double-layer SMA optical device. Moreover, the longitudinally distributed slit mirrors 5 reflect and converge the longitudinal light, and the transversely distributed slit mirrors 5 reflect and converge the transverse light, realizing the overall point-to-point mirror image convergence, that is, the refracted light rays and the incident light rays are on the same side of the normal. Then, since the double-layer SMA optical device has point-to-point imaging, when the display module 21 is a flat panel display, its imaging surface is a plane; when the display module 21 is a three-dimensional light source, its imaging is also a three-dimensional image.

Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical fields, shall be equally included in the patent protection scope of the present invention.
