Description

Technical Field

[0001] The present disclosure relates to the field of display technologies, and in particular, to a vehicle and a projection device. Background Art

[0002] A panoramic display device (PHUD, Panorama-Head-up-Display) outputs an image through an image generation component on a dashboard and projects the image onto a lower region of a windshield for graphic display. An image display effect is optimized by attaching a film or a coating to the windshield. Different from a traditional head-up display device, the panoramic display device does not need to reflect light through multiple reflectors. Generally, the image generation component on the dashboard directly projects light onto the lower region.

[0003] Since the panoramic display device and the head-up display device generally adopt different imaging optical path structures, on a vehicle that needs to perform both panoramic display and head-up display, a set of panoramic display device and a set of head-up display device are usually separately provided. Such a setting method further causes waste of space in the already narrow vehicle space. Summary of the Invention

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some embodiments of the present disclosure, rather than all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present disclosure.

[0038] It should be noted that the terms "second", "first", etc. in the description, claims and the above-mentioned drawings of the present disclosure are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or server comprising a series of steps or components does not necessarily have to be limited to those steps or components clearly listed, but may include other steps or components not clearly listed or inherent to these processes, methods, products or devices.

[0039] Before the embodiments of the present disclosure, the following technical terms are explained:

[0040] An eyebox refers to a conical area between the near-eye display optical system and the eyeball, and it is also the area where the displayed content is the clearest. When the user's eyeball moves within this area, the best imaging effect will be obtained.

[0041] A Head Up Display (HUD) is a driving assistance instrument used in automobiles and is an integrated electronic display device composed of electronic components, display components, controllers, etc. It can project information such as vehicle speed, navigation information, warnings, etc. in the form of images and characters onto the front of the driver through optical components.

[0042] A Panorama-Head-up-Display (PHUD) projects an image output by an image display component on the instrument panel onto the lower area of the windshield to display the image, and this lower area can basically cover the entire lateral area of the windshield.

[0043] Generally speaking, the content form displayed by the head-up display device is generally in three-dimensional form, while the content form displayed by the panoramic display device is generally in two-dimensional form. For example, in some vehicles, three-dimensional information such as lane lines can be displayed through the head-up display device, while two-dimensional information such as vehicle speed, fuel consumption, and warnings can be displayed through the panoramic display device. Therefore, for existing vehicles, in order to be able to comprehensively display relevant information of the vehicle, usually at least one head-up display device and one panoramic display device are respectively installed on the vehicle, and the corresponding image content is projected onto the imaging component based on the installed head-up display device and panoramic display device for imaging, so as to Figure 1 as an example, Figure 1 shows a schematic diagram of the imaging of an imaging component, Figure 1 P1-P3 in it are the image content projected by the panoramic display device, and C1 is the image content projected by the head-up display device.

[0044] Taking P1 and C1 as examples, the imaging of the panoramic display device and the head-up display device will be briefly described. Refer to Figure 2 , for the panoramic display device, its optical imaging structure generally places an image panel and a backlight module (shown in the form of an image generation component 21 in the figure) under the dashboard 28. The light of the backlight module transmits through the image panel and projects the image on the image panel onto the imaging component 22 to obtain the corresponding imaging 26. For the head-up display device, its optical structure generally places an image panel and a backlight module (shown in the form of an image generation component 23 in the figure), a plane mirror 24, and a curved mirror 25 under the dashboard. The principle is that the light of the backlight module transmits through the image panel to generate an image, and the image adjusts the optical path through the plane mirror 24 and the curved mirror 25 and projects onto the imaging component 22 to obtain the corresponding imaging 28. Finally, the user can observe the imaging 26 and the imaging 27 at the corresponding position 29.

[0045] From Figure 2 it can be seen that, on the one hand, these two sets of display devices need to be respectively allocated corresponding space for accommodation, and such an allocation method further compresses the space on the vehicle's dashboard, resulting in space waste; on the other hand, these two sets of display devices respectively require a corresponding set of image generation components for imaging, increasing the production cost of the vehicle.

[0046] The embodiment of the present disclosure provides a projection device. Refer to Figure 3 , the projection device 3 includes an image generation component 31 and a reflection component 32.

[0047] The image generation component 31 is the most important component in the vehicle's display system. The function of the image generation component 31 is to output an image, and it is generally composed of a light source, an image panel, and other optical element components.

[0048] In this embodiment, a first image area 311 and a second image area 312 are provided on the image generation component 31. For the image content formed by different image areas on the image generation component 31 on the imaging component, refer to Figure 4 , the first image 313 corresponds to the first image area 311, and the second image 314 corresponds to the second image area 312.

[0049] The first image area 311 is used to be irradiated by the emitted light to generate the first image 313, and the first image is projected onto the first position 33 of the imaging component 4. The second image area 312 is used to be irradiated by the emitted light to generate the second image 314, and after passing through the reflection component 32, the second image 314 is projected onto the second position 34 of the imaging component 4.

[0050] Among them, the first image 313 displayed in the first image area 311 can be a two-dimensional image or a three-dimensional image; the second image 314 displayed in the second image area 312 can be a two-dimensional image or a three-dimensional image. In this embodiment, it is preferably to set the first image 313 as a two-dimensional image and the image content displayed by the second image 314 as a three-dimensional image. Specifically, the content information included in the first image 313 can be two-dimensional information such as vehicle speed and fuel consumption, and the content information included in the second image 314 can be three-dimensional information such as road conditions. The projection device can project both two-dimensional images and three-dimensional images, so as to integrate the display functions of the panoramic display device and the head-up display device into one.

[0051] The first position 33 and the second position 34 can be specifically referred to Figure 1 , taking the windshield as the imaging component as an example, the first position 33 can be a groove or an opening under the windshield, and the second position 34 can be the glass body of the windshield, so that the second image 3143 realizes virtual reality combination. Figure 1 P1 in Figure 1 can be used as a reference for the first position in this embodiment, Figure 1 C1 in Figure 1 can be used as a reference for the second position in this embodiment. C1 and P1 in

[0052] are located on the driver's side of the vehicle, which is convenient for the driver to observe. In addition, it should be noted that

[0053] is only an example of the first position and the second position on the imaging component, but the specific positions of the first position and the second position are not limited to this, and can be selected according to the specific imaging requirements of the vehicle.

[0054] In one embodiment, since the first image typically displays two-dimensional information such as vehicle speed and fuel consumption, a light-shielding coating is typically applied to the first portion 33 of the imaging assembly to improve image quality, such as resolution. The light-shielding coating may be a black chemical coating, film, or the like.

[0055] Furthermore, if the second image is a three-dimensional image, specifically a three-dimensional image combined with virtual reality, a light-shielding coating is generally not applied to the second position 34 because the light-shielding coating may affect the integration of virtual reality. However, if the second image is also a three-dimensional image, this restriction does not apply.

[0056] In one embodiment, specifically, the reflection assembly 32 includes a first plane mirror 321 and a curved mirror 322 .

[0057] like Figure 3 As shown in FIG, the first plane mirror 321 is disposed on the optical path between the second image region 312 and the curved mirror 322. The first plane mirror 321 is used to reflect the second image 314 to the curved mirror 322. The curved mirror 322 is used to reflect the second image to the second position 34.

[0058] Since the second image 314 generated by the second image area 312 is usually projected onto the curved surface of the imaging component, the function of the reflective component 32 is to fit the curved surface of the imaging component during the projection process to eliminate possible distortion of the second image 314 as much as possible.

[0059] In this embodiment, a first plane mirror 321 is provided to reflect the second image 314 to change the optical path of the second image 314, while the curved mirror 322 is used to fit the curved surface of the imaging component to eliminate the optical distortion of the second image 314, improve the image quality, and thereby enhance the user experience.

[0060] Also, see Figure 5 This embodiment also provides another structure of the reflection component 32. Based on the above embodiment, the reflection component also includes a second plane mirror 323.

[0061] The second plane mirror 323 is disposed on the optical path between the first plane mirror 321 and the curved mirror 322 . The second plane mirror 323 is configured to reflect the second image 314 reflected by the first plane mirror 321 to the curved mirror 312 .

[0062] With the setting of the second plane mirror 323, the imaging light path of the second image 314 is folded again. By adjusting the positions of the various reflectors in the reflective assembly 32, the second image 314 can be accurately reflected to the corresponding position. At the same time, the folding of the light path can effectively compress the space required for the reflective assembly 32, effectively reducing the volume of the projection device.

[0063] It should be noted that the number of the second plane mirrors 322 is at least one, and can be specifically selected according to actual needs, and no special limitation is made here.

[0064] In one embodiment, the projection device further includes a light shielding member (not shown in the figure), and the light shielding member is disposed between the optical path corresponding to the first image 313 and the optical path corresponding to the second image 314.

[0065] Since in this embodiment, the first image area 311 for generating the first image 313 and the second image area 312 for generating the second image 314 are placed on the same image generation component 31, during the projection process of the first image 313 and the second image 314, there may be a problem that the light rays of the two interfere with each other, thereby affecting the imaging effect of the image. To avoid this influence, in this embodiment, a light shielding member is disposed between the optical paths of the first image 313 and the second image 314, and the light shielding member may be a light-shielding cover, but is not limited thereto.

[0066] In addition, in this embodiment, in addition to the above-mentioned light shielding member method, the optical paths of the first image 313 and the second image 314 can also be simulated and designed to obtain an optical path design with the least interference between the first image 313 and the second image 314.

[0067] The specific structure of the image generation component 31 will be described in detail below. Refer to Figure 6 , the image generation component 31 includes a backlight template 315 and an image panel 316.

[0068] Among them, the backlight template 315 is equivalent to a light source, and the backlight template 315 is used to emit light. The image panel 316 is disposed on the light-emitting side 3151 of the backlight template 315. The image panel 316 can generally be a liquid crystal panel. When the light emitted by the backlight template 315 passes through the image panel 316, the image information carried on the image panel 316 is attached to the light rays. Finally, when the light rays are projected onto the imaging component, an image identical to the image displayed on the image panel 316 can be obtained.

[0069] In addition, the image generation component 31 in the above embodiment is provided with a first image area 311 and a second image area 312. Specifically, the first image area 311 and the second image area 312 can be provided on the image panel 316.

[0070] On the basis of the above embodiment, when the second image is a three-dimensional image, in order to obtain the corresponding three-dimensional image, the image generation component 31 further includes a grating 317, and the grating 317 covers the second image area 312 of the image panel 316.

[0071] The specific function of the grating 317 is to split light. The grating 317 can change the imaging of the second image 312 in the user's left and right eyes, creating a binocular parallax between the imaging in the user's left eye and the imaging in the user's right eye, so that the synthesized image in the user's brain is a stereoscopic picture with a sense of depth. By changing the positional relationship between the two images, the binocular parallax is adjusted, causing a change in the virtual image distance perceived subjectively by the user (in fact, the virtual image distance remains unchanged). The closer the two images are to each other, the closer the virtual image distance perceived subjectively by the user; conversely, the farther the two images are from each other, the farther the virtual image distance perceived subjectively by the user.

[0072] Among them, the grating 317 includes a lenticular grating, a diffraction grating, etc., and can be specifically selected according to the actual situation.

[0073] One exemplary embodiment of the present disclosure provides a vehicle. Refer to Figure 5 and Figures 7 - 9 , the vehicle includes a projection device 3 and an imaging component 4 as described in any one of the first aspects.

[0074] Among them, the form of the vehicle can be any one of an automobile, a train, an airplane, etc., and the imaging component 4 can be any one of a display screen, a windshield, etc., and is not particularly limited herein.

[0075] The projection device 3 projects an image onto the imaging component 4 to display a corresponding image (the first image 313 and the second image 314 in this embodiment) on the imaging component 4, and the user can observe the corresponding image at the corresponding position.

[0076] In one embodiment, refer to Figure 5 and Figures 7 - 9 , the vehicle further includes an instrument panel 5. The imaging component 4 is disposed in the first direction of the instrument panel 5, and the projection device 3 is disposed in a cavity in the second direction of the instrument panel 5. The first direction and the second direction are opposite directions. Specifically, the first direction is preferably the upward direction, and the second direction is preferably the downward direction, and can be specifically selected according to the actual situation.

[0077] Regarding the cavity in this embodiment, specifically, at least one light outlet 51 is provided at a position close to the instrument panel 5. The light outlet 51 is used to allow light to pass through the cavity and be emitted to the imaging component 4.

[0078] Specifically, the number of the light outlets 51 can be as shown in Figure 5 and Figure 7 , which is only one; it can also be as shown in Figure 8 and Figure 9 , and is set according to the number of light paths, and is not particularly limited herein. In addition, the position and shape of the light outlet can be designed according to the structure layout of the projection device 3 or the instrument panel 5 of the vehicle, and are not particularly limited herein.

Moreover, the above specific embodiments of this specification have been described. Other embodiments are within the scope of the appended claims.
