Description
Technical Field
The present invention relates to the field of vehicle display technologies, and in particular, to a display device and a vehicle.
Background
Conventional vehicles typically display important information such as vehicle speed, engine speed, gear, water temperature, oil range, etc. on the dashboard and communicate the information to the driver. The instrument panel is generally integrated in a center console below a front windshield and in the front of a carriage, and the instrument panel generally adopts a mechanical pointer or a liquid crystal display screen or both to be used together, and information such as vehicle speed, engine rotation speed, water temperature, oil quantity and the like is transmitted to a driver through an actual pointer or a displayed pointer, an icon and the like. Some middle-high-end vehicle types exist, key information such as navigation information, vehicle speed, vehicle distance and the like is projected through a head-up display system by an optical machine, the optical machine is arranged in a region which is arranged below a front windshield and inside a center console, the optical machine projects light rays emitted by a light source in a designated region of the front windshield through an optical path system, the light rays enter human eyes after being reflected by the front windshield, and an image is formed in the front of a certain distance away from the vehicle head. And part of vehicle types display information indirectly related to driving such as entertainment, air conditioner and the like through a display screen in the center of the center console, so that the information is transmitted to a driver, and the vehicle types display reversing images or images around a vehicle body to the driver through the center display screen, so that better observation experience is brought by utilizing a larger display area of the center display screen.
Because the center console is positioned below the front windshield, when a driver needs to know information such as the speed of the vehicle, the driver needs to slightly lower the head, the line of sight is moved away from the road surface to an observation instrument in the center console, and the human eyes are switched back and forth between the road and the instrument, so that visual fatigue and distraction are easily caused, and potential safety hazards are brought to the driver; in addition, in order to ensure the visibility of the instrument under strong light, a shading component is required to be arranged above the instrument panel on the center console, and the instrument panel is hidden in a region with a certain depth inside the center console, so that a considerable part of the space of the center console is occupied, the size of the center console cannot be further reduced, and the space in a vehicle is occupied; and because the traditional instrument is positioned in the center console, the distance between the traditional instrument and the road surface seen through the front windshield is far, and the traditional instrument is difficult to fuse, and is not generally used for displaying some information (such as navigation prompts, lane information, front vehicle distance, side pedestrians or vehicle early warning and the like) related to the road in real time.
The head-up display adopts the optical machine projection inside the center console, and the light path reflected by the front windshield has a so-called 'eye box', namely: the eyes of a driver can see the image in a quite narrow range, and even if the eyes of the driver are positioned in the eye box, the problem of 'ghosting' is often caused by the superposition of different reflection surfaces of the front windshield; in addition, because different drivers have different heights, sitting postures and the like, the 'eye boxes' must be adjusted according to different persons, and the 'ghosting' problem is relatively serious for partial drivers; furthermore, the head-up display has the problems of limited display picture area, relatively limited content, occupation of the internal space of the center console by the optical machine, and the like.

In an alternative embodiment of the present invention, the light-transmitting member 101 is a hollow glass, and the hollow glass includes two glass layers and a hollow layer between the two glass layers, and the hollow layer is filled with a dry gas, such as dry air, argon or nitrogen.

In an alternative embodiment of the present invention, the second face 1012 of the light transmissive member 101 is provided with an optical film including at least one of an antireflection film (AR film), an anti-fingerprint film (AF film), an anti-glare film (AG film), a combination film of a 1/4 phase retarder and a linear polarization film that are laminated, and the display effect and durability of the display device 1 can be improved by providing the optical film. Specifically, when the optical film includes an antireflection film, the antireflection film can reduce reflection and scattering of external light by the display device 1, and can improve light transmittance and color reduction capability of an optical surface of the display device 1, thereby improving a display effect of the display device 1. For example, the material of the antireflection film may be a porous silica coating, a high-low refractive index laminated coating film, or the like. When the optical film is an AF film, the AF film can improve the anti-fingerprint and anti-oil-stain capabilities of the surface of the display device 1, effectively prevent the residues of fingerprints and oil stains, and simultaneously can improve the hardness and wear resistance of the optical surface.

When the optical film includes an AG film, the AG film may be, for example, diffusely reflective PET or the like, capable of reducing glare and reflection of light caused by reflection of light at the surface of the display device 1, thereby improving the visual comfort and clarity of a driver. When the optical film comprises a combination film of a 1/4 phase delay plate and a linear polarizing film which are laminated, external parasitic light passes through the linear polarizing film and the 1/4 phase delay plate to be changed into linear polarized light and circular polarized light in sequence; after being reflected by metal or other interface layers in the display screen, the light becomes circularly polarized light with opposite rotation directions; then the light passes through a 1/4 phase delay film to become linearly polarized light with the vibration direction perpendicular to the polarization direction of the linearly polarized film; the linearly polarized light cannot pass through, so that the reflection interference of the external environment light is restrained.

When the included angle is smaller than 90 °, the bottom end of the transparent member 101 is closer to the human eye than the top end thereof, so that the angle between the display surface of the display screen 102 and the line of sight of the human eye is closer to vertical, and better visual experience can be obtained, but light rays in the external environment (such as light rays entering the vehicle from above the front windshield, from the sunroof, from the side window, etc.) are reflected by the transparent member 101 and enter the human eye, so that visual observation is disturbed, and therefore, the preferred included angle is greater than or equal to 40 °, the more preferred included angle is greater than or equal to 50 °, and the further preferred included angle is greater than or equal to 60 °. When the included angle is equal to 90 degrees, the light reflected from the external environment is greatly weakened, and the viewing angle between the display screen 102 and the human eyes is still in an ideal area, so that the use experience is better. When the included angle is greater than 90 °, light in the external environment can be prevented from being reflected into human eyes to a great extent, but the viewing angles of the display screen 102 and human eyes are increased, so that viewing of information in the display screen 102 by human eyes is not facilitated, and poor visual experience is brought, therefore, the preferred included angle is less than or equal to 120 °, the more preferred included angle is less than or equal to 110 °, and the further preferred included angle is less than or equal to 100 °.
