[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0036] A head-up display device can generally be used as a driving assistance system and applied to vehicles. Taking a car as an example, the head-up display device can usually be arranged under the instrument panel in the car cab. The head-up display device can be used to project various information (such as speed, engine speed, gear position, navigation, etc.) onto the windshield of the car, so that the driver can see various information without having to lower or turn their head as much as possible, improving driving safety and convenience.

[0037] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a head-up display device provided by the related art. The head-up display device 00 can include: a display panel 10 and a mirror group 20.

[0038] The light-emitting surface of the display panel 10 can face the mirror group 20. The display panel 10 can emit image light beams and project the image light beams onto the mirror group 20. Among them, the image light beams emitted by the display panel 10 can present an image, thereby presenting various information to assist the driver in driving the vehicle.

[0039] The mirror group 20 can include one mirror or multiple mirrors. The mirror group 20 is used to reflect the received image light beams. After the received image light beams are reflected and magnified by one mirror or multiple mirrors, they can be reflected onto the windshield, and the windshield can reflect the received image light beams to the human eye, thereby forming an image.

[0040] Among them, the display panel 10 can include multiple pixel areas. The multiple pixel areas can be arranged in multiple rows and multiple columns. The multiple pixel areas can all emit light. The display panel 10 can emit image light beams through the multiple pixel areas. However, while the mirror group 20 reflects and magnifies the received image light beams, the distance between the light beams emitted by two adjacent pixel areas also becomes larger, so that the resolution of the image presented by the image light beams is lower and the clarity is poorer, resulting in a poor display effect of the head-up display device 00.

[0041] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of a head-up display device provided by an embodiment of this application. Taking a car as an example, the head-up display device 000 can usually be arranged under the instrument panel in the car cockpit. By using lightweight and high-strength materials as the bracket, the stability and durability of the head-up display device 000 are ensured. The head-up display device 000 includes: a first display panel 100, a second display panel 200, and a mirror group 300.

[0042] The first display panel 100 can be used to emit a first image light beam, and a first image can be presented through the first image light beam. The light-emitting side of the first display panel 100 can face the mirror group 300, and the first display panel 100 can emit the emitted first image light beam to the mirror group 300.

[0043] The second display panel 200 can be used to emit a second image light beam, and the second display panel 200 can also transmit the first image light beam. Among them, the second image light beam emitted through the second display panel 200 can present a second image.

[0044] The mirror group 300 can include one mirror or multiple mirrors. Then, the mirror group 300 can reflect the received light once or multiple times, so as to perform magnification. And the mirror group 300 can reflect the light to the windshield G in the vehicle, and the windshield G can reflect the received light to the human eye, so as to present an image.

[0045] Among them, the mirror group 300 can at least be used to reflect the received first image light beam.

[0046] When the mirror group 300 is used to reflect the received first image light beam, the mirror group 300 can reflect the received first image light beam to the windshield G. Then, the windshield G can reflect the received first image light beam to the human eye, so as to present the first image through the first image light beam. And the second image light beam emitted by the second display panel 200 can directly shoot towards the windshield G or the human eye, so as to present the second image through the second image light beam.

[0047] When the mirror group 300 can be used to reflect the received first image light beam and the second image light beam, the mirror group 300 can reflect the received first image light beam and the second image light beam to the windshield G. Then, the windshield G can reflect the received first image light beam and the second image light beam to the human eye, so as to present the first image through the first image light beam and present the second image through the second image light beam.

[0048] It should be noted that the first display panel 100 can include multiple first pixel regions. The first display panel 100 can emit the first image light beam through the multiple first pixel regions. When the mirror group 300 reflects and magnifies the received first image light beam, the distance between the light rays emitted from adjacent first pixel regions will also increase accordingly. Then, the resolution of the first image presented through the first image light beam is relatively low and the clarity is poor.

[0049] In the embodiment of the present application, the projection area of the first image beam intersects with the projection area of the second image beam, so that the first image presented by the first image beam and the second image presented by the second image beam can complement each other, and thus the second image can be fused with the first image to form a unified image screen. Herein, the projection area of the first image beam refers to the overall projection area of the first display panel 100 on the windshield G, and the projection area of the second image beam refers to the overall projection area of the second display panel 200 on the windshield G.

[0050] This can improve the resolution of the image screen, enhance the clarity, and make the display effect more delicate. The second image can be used as a background image or other auxiliary information, and the first image and the second image do not block each other, so the displayed information is also clear and complete, thereby improving the display effect of the head-up display device 000.

[0051] In summary, the embodiment of the present application provides a head-up display device. The head-up display device includes a first display panel, a second display panel, and a mirror group. The first display panel emits a first image beam, and the second display panel emits a second image beam. The projection area of the first image beam intersects with the projection area of the second image beam, so that the first image presented by the first image beam and the second image presented by the second image beam can complement each other, and thus are fused to form a unified image screen. In this way, the resolution of the image screen can be improved, the clarity can be enhanced, and the display effect can be more delicate. At the same time, the second image can be used as a background image or other auxiliary information, and the first image and the second image do not block each other, so the information displayed on the image screen is also clear and complete, thereby improving the display effect of the head-up display device.

[0052] As Figure 3 shown, the first display panel 100 may have a plurality of first pixel regions 101. The plurality of first pixel regions 101 may be arranged in multiple columns along the first direction X and in multiple rows along the second direction Y. The plurality of first pixel regions 101 can all emit light, so the first display panel 100 can emit a first image beam through the plurality of first pixel regions 101.

[0053] As Figure 4 shown, the second display panel 200 may have a plurality of second pixel regions 201. The plurality of second pixel regions 201 may be arranged in multiple columns along the first direction X and in multiple rows along the second direction Y. The plurality of second pixel regions 201 can all emit light, so the second display panel 200 can emit a second image beam through the plurality of second pixel regions 201.

[0054] It should be noted that the second display panel 200 may also have a plurality of transparent regions 202. In the first direction X, the plurality of transparent regions 202 may be alternately arranged with the plurality of second pixel regions 201, and / or, in the second direction Y, the plurality of transparent regions 202 may be alternately arranged with the plurality of second pixel regions 201. Exemplarily, as Figure 4 shown, in the first direction X, the plurality of transparent regions 202 may be alternately arranged with the plurality of second pixel regions 201. Regarding the alternate arrangement of the transparent regions 202 and the second pixel regions 201, the embodiments of the present application do not make any limitations. The embodiments of the present application only use Figure 4 the arrangement shown as an example for illustrative description.

[0055] Among them, the plurality of first pixel regions 101 in the first display panel 100 may correspond to the plurality of transparent regions 202 in the second display panel 200. Since the transparent regions 202 can transmit the light incident on the second display panel 200, at least part of the light emitted from the first pixel regions 101 can pass through the corresponding transparent regions 202 and transmit through the second display panel 200. That is, at least part of the first image light beam emitted from the first display panel 100 can pass through the plurality of transparent regions 202 and transmit through the second display panel 200.

[0056] In this way, the plurality of second pixel regions 201 are used to emit second image light beams, and the plurality of transparent regions 202 are used to transmit at least part of the first image light beam. Then, the projection region of the first image light beam and the projection region of the second image light beam can intersect, so that the first image presented by the first image light beam and the second image presented by the second image light beam can complement each other and be integrated into a unified image screen, thereby making the display of the image screen more delicate and improving the resolution and clarity of the head-up display device 000.

[0057] It should also be noted that the irradiation position of the light emitted from the first pixel regions 101 in the first display panel 100 on the second display panel 200 is at least partially located outside the second pixel regions 201 in the second display panel 200. In this way, the situation where the first image light beam emitted from the plurality of first pixel regions 101 irradiates the second pixel regions 201 can be further reduced. Furthermore, it can be ensured that the first image light beam can pass through the transparent regions 202 and transmit through the second display panel 200 as much as possible to present a relatively complete first image, and at the same time, the interference between the first image and the second image can be reduced to ensure the display effect.

[0058] Optionally, the mirror group 300 includes at least one mirror. The mirror in the mirror group 300 can at least be used to reflect the received first image light beam to the windshield G. Since the windshield G is a curved surface, if all the mirrors in the mirror group 300 are plane mirrors, the first image presented by the first image light beam reflected to the windshield G will be severely distorted.

[0059] Therefore, in the embodiments of the present application, the mirror group 300 may include at least one curved mirror, and the reflecting surface of the curved mirror is an aspherical surface. By calculating and regulating the optical path of the reflected light, the curved mirror can better adapt to the curvature of the windshield G, thereby ensuring the imaging quality, reducing image distortion, and further ensuring the display effect of the head-up display device 000.

[0060] Optionally, the head-up display device 000 may include an image processing and control system. The image processing and control system can process the driving information of the vehicle in real time, thereby controlling the first display panel 100 and the second display panel 200 to display corresponding content, and the display content can change in real time. At the same time, the image processing and control system can precisely control the first image presented by the first image beam and the second image presented by the second image beam to complement each other and seamlessly fuse to form a unified image screen, ensuring the display effect of the head-up display device 000.

[0061] The head-up display device 000 may further include an intelligent optical system. The intelligent optical system can precisely regulate the angles of the mirrors in the mirror group 300 to ensure good imaging quality of the light reflected by the mirror group 300 onto the windshield G. At the same time, the intelligent optical system can also automatically adjust the brightness of the light emitted by the first display panel 100 and the second display panel 200 according to the ambient light and the user's line of sight, so as to better adapt to the environment, meet the user's needs, and ensure the clarity and readability of the projected image screen.

[0062] In a possible implementation manner, the head-up display device 000 may also support human-computer interaction, thereby improving the user experience. Exemplarily, the head-up display device 000 may have a touch function, or the head-up display device 000 may be controlled by voice. In this way, the user can adjust the display effect of the head-up display device 000 or control the opening and closing of the head-up display device 000 through the touch screen or voice control.

[0063] There are various setting methods for the position of the second display panel 200. The embodiments of the present application will take the following four setting methods as examples for illustrative description.

[0064] The first method, please refer to Figure 2 , the light-emitting side of the second display panel 200 may face the mirror group 300, and on the light transmission path between the first display panel 100 and the mirror group 300, the second display panel 200 may be distributed between the first display panel 100 and the mirror group 300.

[0065] In the first method, please combine Figures 2 to 4At least part of the first image light beams emitted from the multiple first pixel regions 101 in the first display panel 100 can pass through the multiple transparent regions 202 in the second display panel 200 to transmit the second display panel 200, and thus be directed towards the mirror group 300. The second image light beams emitted from the multiple second pixel regions 201 in the second display panel 200 can be directly directed towards the mirror group 300.

[0066] In this way, the mirror group 300 can reflect and magnify the received first image light beams and second image light beams, and then project them onto the windshield G. The projection regions of the first image light beams and the second image light beams intersect. The windshield G can reflect the received first image light beams and second image light beams to the human eye, so that a first image is formed by the first image light beams, a second image is formed by the second image light beams, and the first image and the second image complement each other and can be fused to form a unified image screen.

[0067] For the second method, please refer to Figure 5 , the light-emitting side of the second display panel 200 can face the windshield G, and on the light transmission path between the mirror group 300 and the windshield G, the second display panel 200 can be distributed between the mirror group 300 and the windshield G.

[0068] In the second method, please combine Figures 3 to 5 , the first image light beams emitted from the multiple first pixel regions 101 in the first display panel 100 can be directed towards the mirror group 300. At least part of the first image light beams reflected by the mirror group 300 can pass through the multiple transparent regions 202 in the second display panel 200 to transmit the second display panel 200, and thus be directed towards the windshield G. The second image light beams emitted from the multiple second pixel regions 201 in the second display panel 200 can be directly directed towards the windshield G. Among them, the projection regions of the first image light beams on the windshield G and the second image light beams on the windshield G intersect.

[0069] In this way, the windshield G can reflect the received first image light beams and second image light beams to the human eye, so that a first image can be presented by the first image light beams, a second image can be presented by the second image light beams, and the first image and the second image complement each other and can be fused to form a unified image screen.

[0070] For the third method, please refer to Figure 6 , the second display panel 200 can be used to be assembled on the windshield G, and on the light transmission path between the mirror group 300 and the windshield G, the second display panel 200 can be distributed on the side of the windshield G facing the mirror group 300.

[0071] In the third method, please combine Figure 3 ,Figure 4 and Figure 6 Among them, at least some of the first image light beams emitted from the multiple first pixel regions 101 in the first display panel 100 can be directed towards the mirror group 300. The mirrors in the mirror group 300 can reflect the received first image light beams, thereby changing the propagation direction of the first image light beams. At least some of the reflected first image light beams can pass through the multiple transparent regions 202 in the second display panel 200 to transmit through the second display panel 200, and thus be directed towards the windshield G.

[0072] Since the side of the second display panel 200 facing away from the windshield G is the light-emitting side of the second display panel 200, the second image light beams emitted from the multiple second pixel regions 201 in the second display panel 200 can be directly directed towards the human eye. In a possible case, the backlight side of the second display panel 200 can also emit light, and these light beams can be reflected by the windshield G. The reflected light beams can pass through the second display panel 200 and enter the human eye, thereby enhancing the brightness of the second image light beams and further enhancing the brightness of the second image.

[0073] In this way, the windshield G can reflect the received first image light beams to the human eye, while the second display panel 200 can directly direct the emitted second image light beams towards the human eye. Thus, the first image can be presented through the first image light beams, and the second image can be presented through the second image light beams. Since the projection area of the first image light beams intersects with the projection area of the second image light beams, the first image and the second image can complement each other, thereby fusing to form a unified image screen.

[0074] For the fourth method, please refer to Figure 7 , the second display panel 200 can be attached to the reflecting surface of one of the mirrors in the mirror group 300, and in the light transmission path between the mirror group 300 and the windshield G, the second display panel 200 can be distributed on the side where the reflecting surface faces the windshield G.

[0075] In the fourth method, please combine Figure 3 、 Figure 4 and Figure 7 , at least some of the first image light beams emitted from the multiple first pixel regions 101 in the first display panel 100 can pass through the multiple transparent regions 202 in the second display panel 200 to transmit through the second display panel 200, and thus be directed towards the mirror group 300. The mirror group 300 can reflect the received first image light beams, thereby changing the propagation direction of the first image light beams. At least some of the reflected first image light beams can pass through the multiple transparent regions 202 in the second display panel 200 again to transmit through the second display panel 200 and be directed towards the windshield G.

[0076] If the light-emitting side of the second display panel 200 faces the windshield G, the second image light beams emitted from the multiple second pixel regions 201 in the second display panel 200 can directly irradiate the windshield G. In a possible case, light can also be emitted from the backlight side of the second display panel 200. These light beams can be reflected by the reflecting surface of the mirror, and the reflected light beams can pass through the second display panel 200, thereby enhancing the brightness of the second image light beams and further enhancing the brightness of the second image.

[0077] In this way, the windshield G can reflect the received first image light beam and second image light beam to the human eye, thereby forming a first image through the first image light beam and forming a second image through the second image light beam. Since the projection area of the first image light beam intersects with the projection area of the second image light beam, the first image and the second image can complement each other, thereby fusing to form a unified image screen.

[0078] It should be noted that since the windshield G and the reflecting surface of the mirror are curved surfaces, in the third and fourth methods, when the second display panel 200 needs to be assembled onto the windshield G or attached to the reflecting surface of the mirror, the second display panel 200 can be a flexible display panel, so as to better conform to the windshield G or the reflecting surface of the mirror.

[0079] In summary, the embodiment of the present application provides a head-up display device. The head-up display device includes a first display panel, a second display panel, and a mirror group. The first display panel emits a first image light beam, and the second display panel emits a second image light beam. The projection area of the first image light beam intersects with the projection area of the second image light beam. Then, the first image presented by the first image light beam and the second image presented by the second image light beam can complement each other, thereby fusing to form a unified image screen. In this way, the resolution of the image screen can be improved, the clarity can be enhanced, and the display effect can be relatively delicate. At the same time, the second image can be used as a background image or other auxiliary information, and the first image and the second image do not block each other, so the information displayed on the image screen is also relatively clear and complete, thereby improving the display effect of the head-up display device.

[0080] On the other hand, the embodiment of the present application also provides a vehicle. The vehicle may include: a cockpit, and a head-up display device installed in the cockpit.

[0081] The head-up display device can be the head-up display device 000 in any of the above embodiments. The head-up display device 000 may include: a first display panel 100, a second display panel 200, and a mirror group 300.

[0082] The first display panel 100 can be used to emit a first image beam and direct the emitted first image beam towards the mirror group 300. The second display panel 200 can be used to emit a second image beam and can transmit the first image beam. The mirror group 300 is at least used to reflect the received first image beam. Wherein, the projection area of the first image beam intersects with the projection area of the second image beam, so that the first image presented by the first image beam and the second image presented by the second image beam can complement each other, thereby fusing to form a unified image screen.

[0083] It should be noted that in the drawings, the dimensions of layers and regions may be exaggerated for clarity of illustration. Also, it can be understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be an intermediate layer. Additionally, it can be understood that when an element or layer is referred to as being "under" another element or layer, it can be directly under the other element, or there may be more than one intermediate layer or element.
