[0020] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0021] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0022] In this disclosure, unless otherwise stated, "inner" and "outer" refer to the inner and outer contours relative to the outline of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same elements.

[0023] According to a first aspect of this disclosure, a display device is provided, with reference to... Figure 1 As shown, the display device includes a carrier 1, a projection unit 2, and a camera 3. The carrier 1 has a receiving cavity 111; the projection unit 2 is disposed in the receiving cavity 111; and the camera 3 is disposed in the receiving cavity 111. The projection unit 2 is used to project light capable of forming a preset image onto the glass 4, and the camera 3 is used to receive reflected light from the viewing box 5 onto the glass 4.

[0024] Through the above-described technical solution, namely the display device provided in this disclosure, the display device arranges the camera 3 and the projection unit 2 together within the receiving cavity 111 of the carrier 1. The projection unit 2 can project light to form a preset image onto the glass 4 and reflect the light to the viewing box 5 through the glass 4, enabling, for example, the driver or passengers to observe vehicle information. Simultaneously, since the camera 3 is configured to receive reflected light from the viewing box 5 onto the glass 4, it can capture images at the viewing box 5, enabling monitoring of, for example, the driver's state and behavior. The overall structure has a high degree of integration and offers advantages in improving driving safety and comfort. Furthermore, by concealing the camera 3 within the receiving cavity 111 of the carrier 1, the problem of the camera 3 being exposed inside the vehicle cabin is eliminated, thus avoiding discomfort for the driver or passengers caused by the exposed arrangement of the camera 3, and contributing to improved aesthetics within the vehicle.

[0025] It should be noted that the aforementioned camera 3 can be a monitoring device in a vehicle's driver monitoring system (DMS) that can monitor, for example, the state and behavior of the driver. This allows the camera 3 to capture facial images of the driver and use image processing technology to extract features such as dynamic changes in the eyes and mouth, thereby determining the driver's fatigue, distraction, or other dangerous behaviors, and issuing alarms or taking autonomous driving intervention measures when necessary to improve driving safety and driving comfort.

[0026] The specific structure of camera 3 is not specifically limited in this disclosure. Those skilled in the art can choose any camera 3 known in the art to achieve the purpose of monitoring, for example, the state and behavior of the driver, according to actual application needs. Furthermore, the above-mentioned vehicle driver monitoring system can monitor the driver's state and behavior through camera 3, analyze the images of the driver captured by camera 3, and issue alarms or take autonomous driving intervention measures when necessary. These are all things that can be achieved by existing vehicle driver monitoring systems in the art, and will not be described in detail here.

[0027] Furthermore, this disclosure does not specifically limit the structure of the projection unit 2 described above. Those skilled in the art can select any suitable optical imaging device in the art according to actual application needs. For example, the display device can be a head-up display device, and adaptably, the projection unit 2 can be a component of, for example, a head-up display device. For example, the projection unit 2 may include, for example, a picture generation unit (PGU) to enable the generation of images (e.g., vehicle information and navigation information) through the projection unit 2 to be projected onto the glass 4 for observation by the user (e.g., driver or passenger). This disclosure is not limited thereto.

[0028] Furthermore, it should be noted that the aforementioned field of view box 5 refers to, for example, the area within which the driver can clearly see the entire display screen on the glass 4. This disclosure does not specifically limit the size and position of the field of view box 5. Those skilled in the art can design it adaptively according to actual application needs. The purpose is to ensure that drivers of different heights and driving postures can see the entire display screen on the glass 4 within, for example, the field of view box 5.

[0029] In some implementations, reference Figure 1 As shown, the carrier 1 may have an optical path opening 112. For example, the carrier 1 may include a housing 110, which has the aforementioned receiving cavity 111 and an optical path opening 112 communicating with the receiving cavity 111. The light output path of the projection unit 2 (e.g., Figure 1The light path (shown by the solid line in the middle) passes through the light path opening 112, and the light path (e.g., the light entering the camera 3) passes through the light path opening 112. Figure 1 The light path (shown by the dashed line in the middle) passes through the light path opening 112. This arrangement allows both the camera 3 and the projection unit 2 to be hidden inside the housing 110. The housing 110 provides safety protection and eliminates the discomfort caused to the driver or passengers by the exposed arrangement of the camera 3, thus improving the aesthetics of the vehicle interior.

[0030] Furthermore, since the light output path of the projection unit 2 passes through the light path opening 112, and the light input path of the camera 3 also passes through the light path opening 112, images generated by the projection unit 2 (such as vehicle information and navigation information) can be projected onto the glass 4. This allows users (such as drivers or passengers) to observe the images, while the camera 3 can monitor, for example, the driver's state and behavior. Since the camera 3 can directly use the imaging light path of the projection unit 2 to acquire images at the field of view box 5, the shared light path design simplifies the number of optical components and reduces light loss during transmission, which helps improve the imaging effect of the projection unit 2 and the monitoring effect of the camera 3. The overall structure is also more compact, which helps reduce the space occupied by the display device. This allows for greater design space when the display device is applied to vehicles, for example.

[0031] Additionally, in some implementations, references Figure 1 As shown, the display device may also include a reflective structure 6, which is disposed within the housing 111. The reflective structure 6 may be disposed on the light path of the projection unit 2, so that the reflective structure 6 can receive the light emitted by the projection unit 2 and reflect it onto the glass 4. With this arrangement, the projection unit 2 can be hidden within the housing 110 while the image generated by the projection unit 2 (such as vehicle information and navigation information) can be clearly projected onto the glass 4, so that, for example, the driver or passenger can observe the vehicle information.

[0032] Furthermore, in some implementations, references Figure 1 As shown, the reflective structure 6 can be used to receive the reflected light from the view box 5 onto the glass 4 and reflect it to the camera 3. With this arrangement, the camera 3 can be hidden inside the housing 110 while the image at the view box 5 can be reflected to the camera 3 to monitor, for example, the state and behavior of the driver.

[0033] Alternatively, in some implementations, reference is made to Figure 1As shown, the reflective structure 6 may include at least one reflector 610, and the lens of the camera 3 may face the reflective surface of the reflector 610. With this arrangement, the camera 3 can capture images at the field of view box 5, thereby achieving the purpose of monitoring, for example, the state and behavior of the driver. At the same time, the setting of the reflector 610 can reduce the possibility of image distortion and ghosting, improve image clarity, and help improve the monitoring effect of the camera 3.

[0034] Exemplarily, in some implementations, reference is made to Figure 1 As shown, the reflector 610 may include a first reflector 611 and a second reflector 612. The first reflector 611 and the second reflector 612 are arranged such that the light path of the projection unit 2 passes through the first reflector 611 and the second reflector 612 in sequence, so as to achieve the purpose of clearly and accurately reflecting the image (such as vehicle information and navigation information) generated by the projection unit 2 onto the glass 4.

[0035] In addition, such as Figure 1 As shown, the lens of camera 3 can be oriented towards the reflective surface of the second reflector 612, so that the second reflector 612 can reflect the reflected light to camera 3. With this arrangement, since the lens of camera 3 is oriented towards the reflective surface of the second reflector 612, the light path is shorter. This allows the image at the field of view box 5 to be reflected to camera 3 through the reflective structure 6, while reducing the possibility of light path attenuation and helping to improve the monitoring effect of camera 3.

[0036] It is understood that the specific embodiment in which the lens of the camera 3 faces the reflective surface of the second reflector 612 is exemplary. In other alternative embodiments, such as when the reflective structure 6 includes multiple reflectors 610, the lens of the camera 3 can face the reflective surface of any one of the multiple reflectors 610. This disclosure does not specifically limit this variation. Its purpose is to enable the image at the field of view box 5 to be reflected to the camera 3 through the reflective structure 6. Those skilled in the art can design it adaptively according to actual application needs.

[0037] In addition, such as Figure 1 As shown, the area of ​​the reflective surface of the first reflector 611 can be smaller than the area of ​​the reflective surface of the second reflector 612. This arrangement allows the reflective surface of the second reflector 612 to have a larger area, ensuring that the lens of the camera 3 can receive the light reflected from the reflective surface of the second reflector 612 when the lens of the camera 3 is facing the reflective surface of the second reflector 612, thereby improving the monitoring effect of the camera 3.

[0038] In this disclosure, the specific structural shape of the aforementioned reflector 610 (e.g., the first reflector 611 and the second reflector 612) is not specifically limited. Those skilled in the art can design it adaptively according to actual application needs. The purpose is to enable the reflector 610 to reflect the image generated by the projection unit 2 (e.g., vehicle information and navigation information) onto the glass 4, and to reflect the image at the field of view box 5 onto the camera 3 through the reflection structure 6, so as to monitor, for example, the state and behavior of the driver.

[0039] Furthermore, this disclosure does not specifically limit the specific external shape and structure of the housing 110, nor the specific connection methods between the projection unit 2, the camera 3, and the reflection structure 6 and the housing 110. Those skilled in the art can adapt the design according to actual application requirements. The purpose is to ensure that the projection unit 2, the camera 3, and the reflection structure 6 are stably set inside the receiving cavity 111 of the housing 110.

[0040] According to a second aspect of this disclosure, a vehicle is provided, the vehicle including glass 4 and the display device provided in the first aspect. Furthermore, the vehicle also possesses all the beneficial effects of the display device provided in the first aspect, which will not be elaborated further herein.

[0041] In some embodiments, the glass 4 may include a windshield so that images such as vehicle information and navigation information can be projected onto the windshield in front of the driver's line of sight via the projection unit 2, making it easier for the driver to observe. At the same time, the camera 3 can capture images at the field of view box 5 to monitor, for example, the driver's state and behavior. The overall structure has a high degree of integration and has the advantages of improving driving safety and driving comfort.

[0042] In addition, in some embodiments, the vehicle may also include a center console (not shown), and the display device may be installed in the center console, which can make better use of the vehicle's interior space and avoid occupying too much cabin space. The specific connection method between the display device and the center console, as well as the specific external structure of the center console, are not specifically limited in this disclosure. Those skilled in the art can design it adaptively according to actual application needs, with the aim of achieving a stable connection of the display device to the center console.

[0043] Furthermore, considering that in order to facilitate the projection of images such as vehicle information and navigation information onto the windshield in front of the driver's line of sight via the projection unit 2, and to simultaneously monitor the driver's state and behavior via the camera 3, in some embodiments, the display device may be set in the storage space corresponding to the driver's area (not shown) on the center console. This arrangement allows the driver to focus their attention on the road more naturally, while also obtaining relevant driving information, which helps to improve driving safety and driving comfort.

[0044] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0045] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0046] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
