Description

Technical Field

[0001] This disclosure relates to the field of vehicle manufacturing technology, and more specifically, to a display system and a vehicle. Background Technology

[0002] In related technologies, in-vehicle display systems can project driving information such as navigation, vehicle speed, and oil pressure onto the windshield in front of the driver's line of sight to improve driving safety and driving experience. However, when the display device projects, it is easy to cause reflections on side windows or glass roofs, which can interfere with the driver's visual observation and easily cause driver visual fatigue, posing certain safety hazards. Utility Model Content

[0003] The purpose of this disclosure is to provide a display system and vehicle that can reduce the possibility of reflections when the display device projects images, reduce visual interference and alleviate driver visual fatigue, thereby helping to improve driving safety and driving experience.

[0004] To achieve the above objectives, a first aspect of this disclosure provides a display system comprising: glass; a display device for projecting light capable of forming a preset image onto the glass; and a dimming structure connected to the display device such that the light emitted from the display device is transmitted through the dimming structure and then emitted, the dimming structure being used to control the divergence angle of the transmitted light.

[0005] Optionally, the dimming structure includes a grid layer having a plurality of grids arranged at intervals, such that gaps are formed between the plurality of grids for light incident from the display device to be projected onto the glass at a preset angle.

[0006] Optionally, the dimming structure further includes a support layer, which includes a first support layer connected to a first surface of the grid layer facing the display device, and a second support layer connected to a second surface of the grid layer away from the display device. The side of the first support layer away from the grid layer forms a light-incoming surface facing the display device, and the side of the second support layer away from the grid layer forms a light-outcoming surface.

[0007] Optionally, the light-incoming surface is provided with a low-haze coating; and / or, the light-outcoming surface is provided with a haze pattern coating; and / or, a reflective polarizer is provided between the grid layer and the support layer; and / or, the support layer is a PC film.

[0008] Optionally, the light-incoming surface of the dimming structure is connected to the display surface of the display device.

[0009] Optionally, the area of ​​the light-receiving surface is not less than the area of ​​the display surface.

[0010] Optionally, the dimming structure is bonded to the display device.

[0011] Optionally, the glass includes a first glass layer, a second glass layer, and a shielding layer. The first glass layer and the second glass layer are connected face to face, and there is a gap between the first glass layer and the second glass layer. The shielding layer is located in the gap, and the overlapping area of ​​the first glass layer, the second glass layer, and the shielding layer is used for the display device to project the light.

[0012] Optionally, the glass is the windshield of a vehicle, and the shielding layer extends along the width direction of the vehicle.

[0013] Optionally, the number of display devices is multiple, and the multiple display devices are arranged at intervals along the width direction of the vehicle to project multiple preset images onto the glass.

[0014] A second aspect of this disclosure provides a vehicle including the display system provided in the first aspect.

[0015] Through the above-described technical solution, namely the display system provided in this disclosure, the display system connects a dimming structure to the display device so that the light emitted from the display device can be transmitted through the dimming structure and then emitted. Since the dimming structure can control the divergence angle of the transmitted light, it can be understood that the dimming structure can limit the divergence angle of the light emitted from the display device. This ensures that no other light that would interfere with the image is emitted except for the light required to form a preset image on the glass. In this way, the possibility of the light projected by the display device onto the glass reflecting onto other transparent windows (such as side windows or glass roofs) and creating a reflection can be reduced, thereby reducing visual interference and alleviating driver fatigue, which helps to improve driving safety and driving experience.

[0016] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] 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.

[0026] 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.

[0027] The inventor discovered through research that, in the relevant technologies, reference Figure 1 As shown, when the display screen 4 of the in-vehicle display system projects driving information such as navigation, vehicle speed, and oil pressure onto the windshield 5 in front of the driver's line of sight, the large divergence angle of the display device results in the reflection of virtual image light (e.g., light required for human observation) onto the windshield 5. Figure 1 Besides the light ray indicated by the solid line in the middle, there will be other light rays (e.g., Figure 1 The light rays (indicated by the dashed line) will be reflected by the windshield and onto things like the side window glass 6 or the glass roof, forming a reflection 7, which interferes with the driver's vision and can easily cause driver visual fatigue, posing a certain safety hazard.

[0028] Based on this, according to the first aspect of this disclosure, a display system is provided, with reference to Figures 2 to 4 As shown, the display system includes a glass 1, a display device 2, and a dimming structure 3. The display device 2 is used to project light 210 that can form a preset image onto the glass 1. The dimming structure 3 is connected to the display device 2 so that the light 210 emitted by the display device 2 is transmitted through the dimming structure 3 and then emitted. The dimming structure 3 is used to control the divergence angle of the transmitted light 210.

[0029] Through the above-described technical solution, namely the display system provided in this disclosure, the display system connects the dimming structure 3 to the display device 2 so that the light 210 emitted from the display device 2 can be transmitted through the dimming structure 3 before being emitted. Since the dimming structure 3 can control the divergence angle of the transmitted light 210, it can be understood that the dimming structure 3 can limit the divergence angle of the light 210 emitted from the display device 2, thereby ensuring that, apart from the light 210 required for forming a preset image on the glass 1, there are no other lights that could interfere with the image (e.g., light 210). Figure 1 The light emitted by the dotted line in the middle can reduce the possibility of the light projected by the display device 2 onto the glass 1 being reflected onto other transparent windows (such as side windows or glass roofs), thus reducing visual interference and alleviating driver visual fatigue, which helps to improve driving safety and driving experience.

[0030] It should be noted that this disclosure does not specifically limit the specific structure of the display device 2. Those skilled in the art can choose any suitable optical imaging device in the field according to actual application needs. For example, the display device 2 can be a head-up display device, the purpose of which is to project images (such as navigation, vehicle speed, oil pressure and other driving information) onto the glass 1 through the display device 2 so that the user can observe them.

[0031] In addition, in some exemplary application scenarios, the glass 1 mentioned above can be, for example, the windshield of a vehicle. This arrangement is so that driving information such as navigation, vehicle speed, and oil pressure can be projected onto the windshield in front of the driver's line of sight through the display device 2, thereby improving driving safety and driving experience, while also reducing visual interference and alleviating driver visual fatigue.

[0032] Of course, it should be noted that the specific embodiment of the glass 1 as the windshield of a vehicle is exemplary. In other application scenarios, the glass 1 may also be other transparent windows capable of displaying images, and this disclosure is not limited thereto.

[0033] In some implementations, reference Figure 3 and Figure 4As shown, the dimming structure 3 may include a grid layer 310, which has a plurality of grids 311 arranged at intervals, such that gaps 312 are formed between the plurality of grids 311 for light incident from the display device 2 to be projected onto the glass 1 at a preset angle. This arrangement allows the dimming structure 3 to control the divergence angle of the transmitted light 210, thereby limiting the divergence angle of the light 210 emitted from the display device 2, reducing visual interference from reflections, and alleviating driver fatigue, thus contributing to improved driving safety and driving experience. This disclosure is not limited thereto.

[0034] It should be noted that when the light 210 emitted from the display device 2 passes through the gaps 312 between the multiple grids 311, diffraction occurs, causing a change in the direction of light propagation. Therefore, the arrangement of the spaced-apart grids 311 causes the light passing through the grid layer 310 to be concentrated in specific directions or at preset angles after diffraction. In other words, it can be understood that the tilt angle of the grids 311 determines the divergence angle of the light 210 transmitted through the dimming structure 3. Furthermore, this disclosure does not specifically limit the tilt angle of the multiple grids 311, their specific number, the size of the gaps 312 between the grids 311, or the specific material of the grids 311. Those skilled in the art can adaptively design the specific structure of the grid layer 310 according to the divergence angle of the transmitted light 210.

[0035] Furthermore, in some implementations, references Figure 3 and Figure 4 As shown, the dimming structure 3 may further include a support layer 320. The support layer 320 includes a first support layer 321 connected to the first surface 313 of the grid layer 310 facing the display device 2, and a second support layer 322 connected to the second surface 314 of the grid layer 310 facing away from the display device 2. The side of the first support layer 321 facing away from the grid layer 310 forms a light-incoming surface 323 facing the display device 2, and the side of the second support layer 322 facing away from the grid layer 310 forms a light-outcoming surface 324. With this arrangement, the grid layer 310 can be supported by the support layer 320, which helps to ensure that the dimming structure 3 has high reliability and durability, and ensures that the dimming structure 3 can work stably.

[0036] The support layer 320 can be, for example, a PC film. It is understood that the support layer 320 can be made of, for example, a polycarbonate substrate or a similar light-transmitting material, which helps to ensure that the support layer 320 has high structural strength and reliability. This disclosure does not make specific limitations in this regard. Those skilled in the art can adapt the support layer 320 according to actual application needs.

[0037] Optionally, in some embodiments, in order to improve the optical performance of the dimming structure 3, such as... Figure 4 As shown, the light-receiving surface 323 can be provided with a low-fog coating 330. Since the low-fog coating 330 can reduce the fogging effect at the light-receiving surface 323, it helps to improve the light transmittance and clarity.

[0038] In addition, such as Figure 4 As shown, the light-emitting surface 324 can be provided with a fogging pattern coating 340. By providing the fogging pattern coating 340, the light transmittance and clarity at the light-emitting surface 324 can be improved, which helps to improve the optical performance of the dimming structure 3.

[0039] In addition, such as Figure 4 As shown, a reflective polarizer 350 can be disposed between the grid layer 310 and the support layer 320. The reflective polarizer 350 can improve the light transmittance of the dimming structure 3 and reduce the generation of glare, so as to ensure that the dimming structure 3 has good optical performance.

[0040] It should be noted that this disclosure does not specifically limit the specific structure and material of the aforementioned low-haze coating 330, atomized pattern coating 340, and reflective polarizer 350. Those skilled in the art can adapt the design according to actual application requirements, with the aim of improving the optical performance of the dimming structure 3.

[0041] In some implementations, reference Figure 3 As shown, the light-inlet surface 323 of the dimming structure 3 can be connected to the display surface 220 of the display device 2, and the area of ​​the light-inlet surface 323 can be constructed to be no less than the area of ​​the display surface 220. With this arrangement, the light-inlet surface 323 of the dimming structure 3 can completely cover the display surface 220 of the display device 2, so as to control the divergence angle of the transmitted light 210 through the dimming structure 3, thereby limiting the divergence angle of the light 210 emitted by the display device 2, reducing the visual interference of reflections and reducing the driver's visual fatigue, which helps to improve driving safety and driving experience.

[0042] It should be noted that the light-inlet surface 323 of the dimming structure 3 is connected to the display surface 220. This can be understood as the light-inlet surface 323 being directly attached to the display surface 220. Alternatively, when a low-haze coating 330 is provided on the light-inlet surface 323, it can be attached to the display surface 220 through the low-haze coating 330. Or, as will be described below, when the dimming structure 3 is bonded to the display device 2, a transparent adhesive layer can also be provided between the light-inlet surface 323 and the display surface 220. This disclosure is not limited to these.

[0043] Optionally, in some embodiments, the dimming structure 3 can be bonded to the display device 2, offering high reliability and ease of installation. It should be noted that the dimming structure 3 can be constructed, for example, as a privacy screen protector, to facilitate stable bonding of the dimming structure 3 to the display device 2. The dimming structure 3 can be bonded to the display device 2 using any known suitable transparent adhesive layer, and this disclosure is not limited thereto.

[0044] In addition, the aforementioned display device 2 and dimming structure 3 can be adaptively installed in, for example, the center console (not shown) of a vehicle, which can better utilize the interior space of the vehicle and avoid occupying too much cabin space. The specific connection method and specific installation position of the display device 2 and dimming structure 3 to the center console of the vehicle are not specifically limited in this disclosure. Those skilled in the art can design them adaptively according to actual application needs. The purpose is to enable the light emitted by the display device 2 to be transmitted through the dimming structure 3 and projected onto the glass 1 to form a preset image.

[0045] Furthermore, in some implementations, references Figure 3 As shown, the glass 1 may include a first glass layer 110, a second glass layer 120, and a shielding layer 130. The first glass layer 110 and the second glass layer 120 are connected face to face, and there is a gap between the first glass layer 110 and the second glass layer 120. The shielding layer 130 is located in the gap. The overlapping area 8 of the first glass layer 110, the second glass layer 120, and the shielding layer 130 is used for the display device 2 to project light 210. With this arrangement, the shielding layer 130 can absorb the light projected onto the glass 1, which helps to reduce the occurrence of ghosting, improve the display effect, and enhance the image display clarity. Furthermore, the shielding layer 130 can provide a clear boundary for the displayed image, which helps to enhance the visual effect, reduce driver visual fatigue, and improve driving safety and driving experience.

[0046] It should be noted that the aforementioned shielding layer 130 can be prepared by printing with opaque or light-absorbing materials such as ink, and this disclosure does not specifically limit it.

[0047] Additionally, in some implementations, references Figure 2 As shown, the shielding layer 130 can be arranged to extend along the width direction of the vehicle. For example, the shielding layer 130 can extend from one side of the windshield to the other side along the width direction of the vehicle to increase the image display area on the glass 1, thereby achieving a wide field of view and displaying richer image information, and improving the user's driving experience.

[0048] Alternatively, in some implementations, reference is made to Figure 2As shown, there can be multiple display devices 2. For example, there can be three display devices 2. The multiple display devices 2 are arranged at intervals along the width direction of the vehicle to project multiple preset images onto the glass 1. This can cover a wider field of view, provide a more comprehensive display of image information, and enable users to obtain image information from different angles, which helps to improve the user's driving experience.

[0049] According to a second aspect of this disclosure, a vehicle is provided that includes the display system provided in the first aspect. Furthermore, the vehicle also possesses all the beneficial effects of the display system provided in the first aspect, which will not be elaborated further herein.
