In the present embodiment, an apparatus for displaying a naked eye 3D image includes: the key for displaying the naked eye 3D image comprises a starting keycap and a key main body structure. And a control circuit is arranged in the key main body structure and is used for controlling the control information of the target object to which the key belongs.

For clarity, the embodiment is described with reference to fig. 1, and the key 10 includes an actuating key cap 11 and a key main body structure 12. The target object can be a vehicle, correspondingly, the key can be a key starting button of the vehicle, the control circuit is a starting control circuit of the vehicle, and the control information is information such as ignition voltage for starting the vehicle. The target object may also be an air conditioner in the vehicle, and accordingly, the key may be a switch key of the air conditioner, the control circuit may be a switch circuit of the air conditioner, and the corresponding control information may be understood as information for starting the air conditioner, such as a starting current and voltage of the air conditioner. It can be understood that the key may be not only a vehicle start key or an in-vehicle air conditioner switch key, but also any other key in the vehicle that needs to display a 3D image on the key.

At this time, based on the mechanical movement, a start control circuit provided inside the key main body structure 12 controls information related to a relay and a starter to be started, so that the vehicle can be started smoothly.

On the basis of the technical scheme, the top of the key main body structure 12 is provided with an adapter plate connector 13, the adapter plate connector 13 is a connector used for driving the LED lamp 14 to be lightened,

the adapter board plug-in 13 is connected with a control circuit, and the control circuit can control the adapter board plug-in 13, so that the adapter board plug-in 13 drives the LED lamp 14 to light.

On the basis of the technical scheme, the light guide plate 15 is arranged above the LED lamp and used for exciting the patterns etched on the light guide plate 15 to perform 3D display when the LED lamp 14 is driven, so as to obtain a 3D image. The light guide plate 15 may be understood as a light guide sheet, and the pattern on the light guide plate 15 is a 2D pattern corresponding to a 3D image. For example, the pattern on the light guide plate 15 is a LOGO image corresponding to the brand LOGO of an automobile. Specifically, set up light guide plate 15 in the top of LED lamp 14, after the LED lamp is driven, the light that the LED lamp sent takes place the total reflection in the leaded light piece, arouse the 2D pattern that has printed among the leaded light piece, thereby form the 3D pattern that can the bore hole see in the air, give the warning of a bore hole 3D pattern of automobile user, let the user can more clear understanding current ignition state of car, bring science and technology sense for the user, increase better car and use and experience.

On the basis of the above technical solution, the device for displaying a naked eye 3D image further includes a silicone back plate 16 disposed between the light guide plate 15 and the LED lamp 14, so as to perform buffering based on the silicone back plate 16 when the key is pressed or rebounded. The silica gel back plate 16 has the characteristics of softness and elasticity, the silica gel back plate 16 is arranged between the light guide plate 15 and the LED lamp 14, and the silica gel back plate 16 is in seamless close contact with the light guide sheet 15. Any damage to light guide sheet 15 caused by pressing or natural springback when the key is pressed can be prevented, and a buffering effect is achieved.

On the basis of the above technical solution, the device for displaying a naked eye 3D image further includes: a dust-proof gasket 17 is provided between the light guide plate 15 and the start key cap 11 to cushion based on the dust-proof gasket 17 and to block dust from falling on the light guide plate based on the dust-proof gasket 17 when the start key cap 11 is pressed.

Here, the viewing angle is an observation angle at which a user can see a 3D image emitted from the light guide plate 15. For example, the viewing angle of the light guide plate 15 is 90 ° horizontally (i.e., 45 ° leftward and 45 ° rightward), and 30 ° vertically (15 ° upward and 15 ° downward), and the user can see the 3D image within the above viewing angle range. The setting position of the key can be understood as the arrangement position of the starting key on the vehicle, and the pupil view can take the position of the central point of the ellipse of the eye of the user as the pupil view angle. The deflection angle information may be understood as the angle of the pattern on the light guide plate 15 to the X-Y plane and to the X-Z plane in a cartesian coordinate system.

It should be noted that the optimal angle for the user to view the 3D image is that the glasses of the user face the light guide plate 15, because the 3D effect can be really observed only when the movement is implemented (the viewing angle changes), and when the glasses face the light guide plate, the human eyes are implemented at the angle of maximum displacement viewing, that is, the optimal viewing angle, when the movement is implemented leftwards/rightwards and upwards/downwards.

Specifically, the included angle of the pattern on the light guide plate 15 in the cartesian coordinate system with respect to the X-Y plane and the included angle with the X-Z plane may be determined based on the visible angle of the light guide plate 15, the key arrangement position, and the pupil viewing angle, and the pattern may be etched on the light guide plate 15 according to the determined included angle information based on the determined included angle information.

In this embodiment, the method for calculating the included angle between the image on the light guide plate and the horizontal direction includes: as shown in fig. 2, if the angle between the line connecting the center point of the eye ellipse and the center point of the light guide sheet and the horizontal plane (XY plane) is α, the angle θ 1 between the image on the light guide sheet and the horizontal direction is:

θ1＝90°-α

When a user normally views the light guide plate 15, the brightness of the LED lamp 14 can be seen at the edge of the light guide plate, that is, the light leakage phenomenon occurs at the edge of the light guide plate 15, and the area needs to be shielded.

Specifically, dustproof gasket 17 is the toroid shape, and toroidal shape's dustproof gasket 17 is wrapping up around light guide plate 15, when playing buffering and dirt-proof effect, can also shelter from the light leak of 15 edges of light guide plate, improves user's visual experience.

On the basis of the technical scheme, the radius of the circular ring shape is determined based on the first distance, the second distance and the radius of the light guide plate.

The first distance is the distance from the pupil to the light guide plate, and the second distance is the thickness information of the light guide plate.

Specifically, as shown in fig. 4, which is a schematic diagram of determining a radius of the dust-proof gasket according to the embodiment of the present invention, an area of an enlarged area in the diagram is a minimum width of a shielding ring of a light leakage area of the circular light guide plate 15, and a calculation method of the minimum width includes:

wherein r is the radius of the light guide sheet, D1 is the distance from the user's pupil to the light guide plate, and D2 is the thickness of the light guide plate.

On the basis of the technical scheme, the method further comprises the following steps: set up black coating film layer in the central zone of starting the key cap surface to when the LED lamp is driven, see through black coating film and show the 3D pattern.

It can be understood that in order to block the edge light leakage phenomenon, black paint is arranged at the edge of the outer surface of the start keycap 11, the paint is opaque, and the center of the start keycap 11 is in a transparent non-painting state, but in this state, the middle of the surface of the start keycap 11 is transparent, the edge is black, and the appearance is not beautiful.
