Description

Display assembly, vehicle display system, vehicle Technical Field

[0001] The present disclosure relates to the field of vehicles, and more particularly to the field of vehicle display systems. More specifically, the present disclosure relates to a display assembly, a vehicle display system including the display assembly, and a vehicle including the display system. Background Art

[0002] As automotive technology continues to advance, so too are in-vehicle information display systems. Traditional in-vehicle information display systems typically employ a split design, distributing different functional modules (such as navigation, audio controls, and vehicle speed) across the dashboard. This design not only consumes significant dashboard space but also presents limitations in terms of visual quality and user experience.

[0003] In recent years, telescopic displays (also known as "transverse" or "integrated" displays) have become a new trend in in-vehicle information display systems. By integrating multiple functional modules into a larger display, telescopic displays enhance the convenience of information display and improve the user's driving experience.

[0004] However, the long-span display currently used in vehicles is typically placed above the dashboard, which somewhat undermines the overall appearance of the dashboard. Furthermore, this arrangement obscures the vehicle's interior design behind the long-span display, affecting the driver's field of view and reducing the aesthetic appeal of the vehicle's interior.

[0005] Therefore, it is necessary to provide a display component that can not only expand the occupants' forward field of view, but also not affect the vehicle's front information display and the integrity and aesthetics of the vehicle's interior design, thereby improving the user experience. Summary of the Invention

[0035] In this specification, when describing the structural position of various components, directional terms such as "above" and "below" are not absolute but relative. For example, "above" and "below" may be defined relative to the viewing direction. These directional terms are appropriate when the components are arranged as shown in the figures. However, if the position of the components in the figures is changed, these directional terms should be modified accordingly. Furthermore, "inside" is defined relative to the inside-outside direction of the vehicle. For example, "inside" refers to the side facing the interior of the vehicle.

[0036] In this document, unless otherwise specified or limited, the terms "installation" and "arrangement" should be understood broadly. For example, they can refer to fixed installation, removable installation, or integrated installation; they can refer to direct installation or indirect installation through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this document based on the specific circumstances.

[0037] In this article, "front" and "rear" are relative to the longitudinal direction of the vehicle. In addition, "lateral" refers to the direction of the vehicle's relatively smaller size, which can also be called the width direction, and "longitudinal" refers to the direction of the vehicle's relatively larger size, which can also be called the length direction, and also indicates the direction of travel.

[0038] Preferred embodiments of the present disclosure will be described below with reference to FIG. 1 to FIG. 8 .

[0039] The display system of a vehicle according to the present disclosure includes a display assembly 1 and a projection device 2, wherein the projection device 2 is used to project projection light onto the display assembly 1, that is, the projection device 2 is equivalent to a light source, and the display assembly 1 is used to reflect the projection light toward the occupants. In addition, the display assembly 1 can also transmit ambient light. In certain embodiments, the projection device 2 can be integrated with the vehicle's electronic control unit (ECU), vehicle controller unit (VCU), or body controller unit (BCM) to provide real-time vehicle information. The vehicle information provided by the projection device 2 can include, for example, vehicle speed, mileage, fuel level, remaining battery life, warning information, navigation, etc. Taking the embodiment of FIG4 as an example, the projection device 2 is installed in a recess 31 on the top of the vehicle's instrument panel 3 in the longitudinal direction away from the occupant, that is, in the recess 31 between the back side of the top of the instrument panel 3 and the vehicle's front windshield 4. The display assembly 1 is installed on the instrument panel 3 between the recess 31 and the front windshield 4 (as shown in the dashed box A in FIG7). The occupants can see the virtual image 6 presented in the dashed area shown in FIG4 through the display assembly 1. In this way, the passenger on the display side of the display assembly 1 can not only see the projected image presented by the projection light from the projection device 2 , but can also see the external environment of the vehicle through the display assembly 1 .

[0040] The structure of the display assembly 1 will be described in detail below with reference to FIG. 1 to FIG. 3 .

[0041] As shown in FIG1 , a display assembly 1 according to an embodiment of the present disclosure includes a translucent and semi-reflective layer 11, a dimming layer 12 with variable transmittance, a transparent substrate 13, and a dimming layer transmittance control unit (not shown). The translucent and semi-reflective layer 11, the dimming layer 12, and the transparent substrate 13 are stacked in sequence along the viewing direction, with the translucent and semi-reflective layer 11 located above the dimming layer 12 and the transparent substrate 13 located below the dimming layer 12. In other words, the translucent and semi-reflective layer 11 is positioned closer to the occupant relative to the dimming layer 12, and the transparent substrate 13 is positioned farther away from the occupant relative to the dimming layer 12. The translucent and semi-reflective layer 11 reflects the projection light from the projection device 2 to present the projection image from the projection device 2 to the occupant. In the case shown in FIG4 , the translucent and semi-reflective layer 11 is arranged on the side facing the occupant. The transparent substrate 13 is used to receive ambient light and transmit the ambient light. In the case shown in FIG4 , the transparent substrate 13 is arranged on the side facing the front windshield 4 of the vehicle. The dimming layer 12 receives ambient light from the transparent substrate 13 and transmits the received ambient light at a variable transmittance. The semi-transmissive and semi-reflective layer 11 not only reflects the projection light but also receives ambient light from the dimming layer 12 and transmits the received ambient light, so that the occupants can see the external environment of the vehicle through the display assembly 1.

[0042] In this way, the display component 1 according to this embodiment can enable the occupants to see the reflected vehicle information and the transmitted external environment of the vehicle through the display component 1. The dimming layer 12 has a variable transmittance, and the transmittance of the display component 1 to ambient light can be adjusted as needed. When the variable transmittance is low, better contrast of the projected image is achieved, reducing the impact of ambient light on the projection display effect. When the variable transmittance is high, the transparency of the display component 1 is high, which does not affect the field of view of the occupants and improves the user experience. In addition, since the projection device 2 projects the image onto the display component 1 and the display component 1 is independently arranged in the vehicle, the arrangement position and shape of the display component 1 are not restricted by components such as the front windshield 4, as long as the projected image can be displayed to the occupants.

[0043] In an alternative embodiment, transparent substrate 13 can also be a non-transparent substrate. In this case, the non-transparent substrate does not receive ambient light, and transflective layer 11 only reflects the projected image from projection device 2. The dimming layer 12 can be used to adjust the contrast of the projected image to adjust the display quality. For example, passengers can see reflected vehicle information through display assembly 1. In this way, display assembly 1 can function as an independent display screen (e.g., a dashboard display) or a decorative component (e.g., an illuminated door trim).

[0044] In some embodiments, the dimming layer transmittance control unit is electrically connected to the dimming layer, that is, the dimming layer 12 can adjust the variable transmittance under the control of an electrical signal. In this case, the variable transmittance can be adjusted by the dimming layer transmittance control unit, and the dimming layer transmittance control unit can send an electrical signal to the dimming layer 12 according to the user's adjustment needs or automatically. For example, when the dimming layer transmittance control unit sends an electrical signal according to the user's adjustment needs, the user can select the desired variable transmittance on the interactive component to send an adjustment instruction to the dimming layer transmittance control unit, and the dimming layer transmittance control unit sends an electrical signal to the dimming layer 12 based on the adjustment instruction. In some embodiments, the interactive component can be a touch screen, such as a central control screen of a vehicle, or a button, such as a rotary button, etc., which is not limited here. When the dimming layer transmittance control unit automatically sends an electrical signal, the dimming layer transmittance control unit can automatically adjust the variable transmittance according to the brightness of the ambient light. For example, when the brightness of the ambient light is high, the dimming layer transmittance control unit can reduce the variable transmittance. When the brightness of the ambient light is low, the dimming layer transmittance control unit can increase the variable transmittance to enhance the display effect of the projected image. It is understandable that the adjustment method of the variable transmittance is not limited to this. The dimming layer 12 can also adjust the variable transmittance under the control of a magnetic signal or mechanical control. In addition, the dimming layer transmittance control unit can be, for example, a control unit of a vehicle controller (VCU), a control unit of a body controller (BCM), or a control unit of an infotainment system.

[0045] As shown in Figure 2 , according to another embodiment, the display assembly 1 may further include a texture layer 14. Texture layer 14 may be located between the dimming layer 12 and the transparent substrate 13. Texture layer 14 may, for example, display wood grain, stone grain, or water ripples. In this way, if the dimming layer 12 has a high variable transmittance, the display assembly 1 can be used as a decorative component, displaying the texture of texture layer 14 and enhancing the aesthetics of the vehicle interior design.

[0046] As shown in FIG3 , according to another embodiment, the display assembly 1 may further include a backlight layer 15, which may be located between the texture layer 14 and the transparent substrate 13. The backlight layer 15 can provide lighting effects. Thus, if the variable transmittance of the dimming layer 12 is high, the display assembly 1 can display a texture with a lighting effect, further enhancing the decorative effect of the display assembly 1 and improving the aesthetics of the vehicle interior design.

[0047] In some embodiments, the variable transmittance may include a first transmittance and a second transmittance. The first transmittance may be the low transmittance of the dimming layer 12, at which the dimming layer 12 can be dimmed to a dark color. The first transmittance may be in the range of 1% to 50%. The second transmittance may be the high transmittance of the dimming layer 12, at which the dimming layer 12 can be dimmed to a light color or transparent state. The second transmittance may be in the range of 3% to 90%. In addition, the first transmittance should be less than the second transmittance. For example, the first transmittance may be 5% and the second transmittance may be 35%. It is understood that the value range of the variable transmittance is not limited to this and can be changed as needed. In some embodiments, the semi-transparent and semi-reflective layer 11 can reflect the projection light from the projection device 2 within a reflectivity range of 10% to 50%. For example, the reflectivity may be 35%. It is understood that the value range of the reflectivity of the semi-transparent and semi-reflective layer 11 is not limited to this and can be changed as needed.

[0048] In some embodiments, the display component 1 can be constructed into a curved surface. In this way, the display component 1 can be integrated with the interior design of the vehicle and can more naturally adapt to the curve of the human eye when the user is watching, reducing visual fatigue. It is understandable that the configuration of the display component 1 is not limited to this. The display component 1 can also be constructed into a flat surface, a combination of flat surfaces and flat surfaces, or a combination of flat surfaces and curved surfaces. Additionally, the display component 1 can be made of a flexible material so that the display component 1 is flexible as a whole. That is, each layer of the display component 1 is made of a flexible material. Flexible materials can better adapt to curved or irregularly shaped surfaces, reduce the thickness of the display component 1, make it occupy less space, and save space inside the vehicle. Exemplarily, the flexible material can be a combination of one or more of a polyimide (PI) film, a polyester (PET) film, and a liquid crystal polymer (LCP) film, wherein the various layers can be selected from the same or different materials as needed to achieve their respective functions.

[0049] In addition, the multiple layers stacked in the display assembly 1 may be bonded together by gluing and / or electrostatic attachment, etc., which is not limited in the embodiments of the present disclosure.

[0050] Other exemplary arrangements of the display system will be described below with reference to FIG. 5 to FIG. 8 .

[0051] As shown in Figures 5 and 7 , the display system can also be located on the passenger-facing side of the vehicle's instrument panel 3, specifically, at the solid-line box B in Figure 7 . Specifically, the projection device 2 can be located on a platform 32 on the passenger-facing side of the vehicle's instrument panel 3, and the display assembly 1 can be located on the instrument panel 3 above the projection device 2, allowing the user to more clearly see the vehicle information displayed by the display assembly 1 at a close distance.

[0052] As shown in Figures 6 and 8 , the display system can also be installed on the inside of a vehicle's door panel, as indicated by the dashed box C in Figure 8 . Specifically, the projection device 2 can be installed on the vehicle's door panel 5, and the display assembly 1 can be installed on the door panel 5 above the projection device 2. In particular, the projection device 2 can be installed on the armrest 51 of the vehicle's door panel 5, and the display assembly 1 can be installed at the front end of the door panel 5, as indicated by the circle D in Figure 8 . In this manner, the display assembly 1 can also function as an electronic exterior rearview mirror. In this case, the display system can be installed on the vehicle's door panels facing the driver and passenger seats, and the projection device 2 can project images of the vehicle's external environment, reducing the driver's blind spots when turning, reversing, and other situations, thereby improving driving safety.

[0053] In the above two arrangement positions, the display assembly 1 can be the display assembly shown in Figures 2 and 3. In this way, when there is no need to display a projected image, the display assembly 1 can be used as a decorative component to improve the aesthetics of the vehicle interior design.

[0054] It should be understood that the embodiments shown in the figures only show optional shapes and arrangements of display components and display systems according to the present disclosure. However, they are only illustrative and not restrictive. Other shapes and arrangements may also be adopted without departing from the spirit and scope of the present disclosure.

However, it is understood that, based on the creative ideas of the present disclosure, those skilled in the art may make various changes and improvements to the above-disclosed concepts, all of which fall within the scope of protection of the present disclosure.
