DETAILED DESCRIPTION

(13) Hereinafter, in order to describe the disclosure, embodiments according to the disclosure will be described in more detail with reference to the accompanying drawings. Like reference numerals refer to like elements throughout the detailed description.

(14) FIG. 1 is a diagram illustrating a state in which a cluster 1 is installed in a vehicle according to an embodiment of the disclosure. FIG. 2 is a diagram illustrating a state in which the cluster 1 is installed in a vehicle according to an embodiment of the disclosure from a driver's point of view.

(15) As shown in FIGS. 1 and 2, the cluster 1 according to an embodiment of the disclosure is installed inside a vehicle body. Specifically, the cluster 1 may be installed in front of the driver. This is an example, and the cluster 1 according to an embodiment of the disclosure is not limited to be installed at a specific location inside the vehicle.

(16) The cluster 1 according to an embodiment of the disclosure may output a variety of information such as RPM, driving speed, fuel efficiency, fuel amount, and mileage of the vehicle. The cluster 1 according to an embodiment of the disclosure outputs predetermined information as a 3D image in a specific space between the driver and the cluster 1.

(17) That is, the image information output through the cluster 1 may have a form of the 3D image output in the specific space.

(18) An interface of a specific 3D image may be implemented in an appropriate form according to an embodiment to which the disclosure is applied.

(19) In an embodiment of the disclosure, a case in which the cluster 1 is positioned in front of the driver will be described as an example.

(20) FIG. 3 is a front view illustrating the cluster 1 according to an embodiment of the disclosure, and FIG. 4 is a perspective view illustrating the cluster 1 according to an embodiment of the disclosure.

(21) As shown in FIGS. 3 and 4, the cluster 1 according to an embodiment of the disclosure forms an output image 10 that is a 3D image in front of the cluster 1 in such a manner that the output image 10 is spaced apart from the cluster 1. The output image 10 is obtained by converting a 2D image output through the cluster 1. When information expressed in the cluster 1 is referred to as information of a first area 12, a second area 14, and a third area 16 for convenience, only an area configured in advance by the user may be output as the output image 10 that is a 3D image. That is, the area of the information output through the cluster 1 may be divided into a plurality of areas such as the first area 12 to the third area 16. Each of the divided areas may be output as a 2D or 3D image by a user's selection.

(22) FIG. 5 is a diagram illustrating the principle of the cluster 1 according to an embodiment of the disclosure, FIG. 6 is a conceptual diagram illustrating the principle of the cluster 1 according to an embodiment of the disclosure, and FIG. 7 is a cross-sectional view illustrating a structure of a spatial image panel 200 in the cluster 1 according to an embodiment of the disclosure.

(23) As shown in FIGS. 5 to 7, the cluster 1 according to an embodiment of the disclosure includes a display 100 and a spatial image panel 200. The display 100 may be implemented as various types of screen display devices. In an embodiment of the disclosure, the display 100 may be an LCD or OLED display 100.

(24) The display 100 may be constituted of a screen that outputs a 2D image or a set of light sources. The spatial image panel 200 is disposed in front of the display 100 and transmits an image output through the display 100 to output the transmitted image as a 3D image in a predetermined space.

(25) In an embodiment of the disclosure, the spatial image panel 200 may be constituted of a micro-lens array (MLA).

(26) The spatial image panel 200 includes a first lens array 210, a second lens array 220, and a refractive medium 230. The first lens array 210 is provided by disposing first lenses 212 in a predetermined pattern. The second lens array 220 is provided by disposing second lens 214 in a predetermined pattern. The first lens 212 and the second lens 214 correspond one-to-one, respectively, and are positioned so that light passing through the first lens 212 and the second lens 214 overlaps.

(27) Specifically, the display 100 forms a single plane, and a 2D image is output through one surface of the display 100. In addition, the spatial image panel 200 is also formed as a surface that transmits the 2D image output through one surface of the display 100. The spatial image panel 200 is constituted of the first lens array 210 and the second lens array 220 in which the first lens 212 and the second lens 214 are gathered to form a plane, respectively. The first lens 212 and the second lens 214 included in each of the first lens array 210 and the second lens array 220 are respectively arranged to correspond one-to-one, and light passing through the first lens array 210 and the second lens array 220 overlaps.

(28) The refractive medium 230 is disposed between the first lens array 210 and the second lens array 220. Alternatively, the first lens array 210 and the second lens array 220 may be disposed in a space surrounded by the refractive medium 230. The refractive medium 230 has a refractive index different from that of air. The refraction medium 230 serves to enlarge the viewing angle of light passing between the first lens array 210 and the second lens array 220.

(29) As shown in FIGS. 6 and 7, the 2D image output through the display 100 passes through the first lens array 210, the refractive medium 230, and the second lens array 220. Next, the 2D image passing through the spatial image panel 200 is imaged as a 3D image in front of the spatial image panel 200. The imaged means that an image that can be observed through the driver's eyes is formed in a space.

(30) Accordingly, the output image 10 is formed as a 3D image in a space between the cluster 1 and the driver and in a predetermined space. The output image 10 may include information such as a vehicle or environment.

(31) More specifically, the first lens array 210 and the second lens array 220 have the first lenses 212 and the second lenses 214 arranged in the same pattern, respectively. The first lens 212 of the first lens array 210 and the second lens 214 of the second lens array 220 overlap, respectively. The first lens array 210 and the second lens array 220 may be symmetrical to each other with the refractive medium 230 interposed therebetween.

(32) That is, a 2D image is output through one surface of the display 100. The spatial image panel 200 is installed at a predetermined interval on one surface on which the image of the display 100 is output. The 2D image output through one surface of the display 100 passes through the spatial image panel 200 and is output as a 3D image in a predetermined space. In the cluster 1 according to an embodiment of the disclosure, the 3D image output through the spatial image panel 200 is formed in a specific space located between the driver and the cluster provided on the vehicle body.

(33) FIG. 8 is a diagram illustrating a rail 240 and a sliding unit 250 provided in the spatial image panel 200 in the cluster 1 according to an embodiment of the disclosure.

(34) As shown in FIG. 8, in front of the display 100, the spatial image panel 200 may move away from or closer to the display 100.

(35) Specifically, a rail 240 is provided on one surface on which the 2D image of the display 100 is output, along a direction in which the image is output from the display 100. At least one rail 240 may be provided, and a thread may be formed on the outer periphery of the rail 240.

(36) The sliding unit 250 that is transferred along the longitudinal direction of the rail 240 as the rail 240 rotates is provided. The first lens array 210, the second lens array 220, and the refractive medium 230 may be fixed to the sliding unit 250. That is, the spatial image panel 200 may be fixed to the sliding unit 250.

(37) Accordingly, as the rail 240 rotates, the spatial image panel 200 moves close to or away from the display 100.

(38) When the spatial image panel 200 moves close to the display 100, a position at which a 3D image is formed is provided close to the cluster 1. Conversely, when the spatial image panel 200 moves away from the display 100, the position at which the 3D image is formed moves away from the cluster 1. Accordingly, when the spatial image panel 200 is operated far from the display 100, the driver can see the output image 10 output as the 3D image more closely.

(39) Accordingly, in an embodiment of the disclosure, the spatial image panel 200 may be operated in conjunction with a variable indicating a vehicle state such as a mileage of the vehicle.

(40) Specifically, when the speed of the vehicle is greater than or equal to a predetermined speed, the spatial image panel 200 may be configured to be closer to the display 100. Alternatively, the spatial image panel 200 may be configured to move away from the display 100 when the vehicle speed is less than or equal to a predetermined speed or when the vehicle is placed under a predetermined situation, such as when entering a child protection area.

(41) Through this, by varying the size of the 3D output image 10 that the driver can identify according to the driving situation or state of the vehicle, there is an effect of further enhancing the user's identification.

(42) FIG. 9 is a state diagram illustrating a state in which a switching layer 400 transmits light without refraction of the light in the cluster 1 according to an embodiment of the disclosure, and FIG. 10 is a state diagram illustrating a state in which the switching layer 400 refracts and transmits light in the cluster 1 according to an embodiment of the disclosure.

(43) As shown in FIGS. 9 and 10, the cluster 1 according to an embodiment of the disclosure may further include a switching layer 400.

(44) The switching layer 400 may be provided in the form of a panel, and the degree of refraction of transmitted light changes according to the voltage of an applied current. The switching layer 400 may be disposed between the first lens array 210 and the second lens array 220. Alternatively, the switching layer 400 may be disposed between the first lens array 210 and the display 100.

(45) The switching layer 400 directly transmits light as shown in FIG. 9 in a state in which a current of a specific voltage is applied. Accordingly, a 2D image output through the display 100 passes through the spatial image panel 200 to be imaged as a 3D image, and the driver can observe the 3D output image 10 provided in front of the cluster 1.

(46) In addition, when the voltage applied to the switching layer 400 is changed as shown in FIG. 10, the light passing through the switching layer 400 is refracted. Accordingly, the 2D image first output through the display 100 is not converted into the 3D output image 10.

(47) That is, by adjusting the voltage applied to the switching layer 400, a specific portion or the whole of the cluster 1 may selectively output one of 2D or 3D images.

(48) The output 3D image may be a specific area or specific information of the cluster 1 designated by the user as described above. The user can selectively convert the specific area and specific information of the cluster 1 into a 2D or 3D image.

(49) FIG. 11 is a state diagram illustrating a state in which an air touch sensor 300 detects a driver's hand and converts the detected information into an input signal in the cluster 1 according to an embodiment of the disclosure.

(50) As shown in FIG. 11, the cluster 1 according to an embodiment of the disclosure further includes an air touch sensor 300. The air touch sensor 300 detects that a predetermined object approaches the front of the cluster 1.

(51) The air touch sensor 300 detects that the driver's hand enters a predetermined space. In addition, the air touch sensor 300 first collects the position of the 3D output image 10 output through the cluster 1, and determines whether the driver's hand approaches the 3D output image 10.

(52) That is, the air touch sensor 300 is interlocked with a controller and transmits object information detected from the front to the controller. Information of the output 3D output image 10, in particular, image-formed position information is stored in the controller. In addition, information for each portion of the output image 10 to be output is stored.

(53) When the user's hand detected through the air touch sensor 300 reaches a specific position of the 3D output image 10, the controller may operate a specific device according to a predetermined configuration.

(54) Specifically, when the driver touches the 3D output image 10 formed on the space, the air touch sensor 300 detects the touch as an input signal, and the controller interprets the input signal and performs an appropriate output.

(55) For example, the above operation may be an operation such as adjusting the size of the 3D output image 10, adjusting the volume of the 3D output image, or adjusting the brightness of the 3D output image 10. Alternatively, the above operation may be implemented in various forms, such as selecting a type of an image to be output.

(56) In the above, embodiments of the disclosure have been described with drawings, which are exemplary and the disclosure is not limited to the above-described embodiments and drawings. It is apparent that those of ordinary skill in the art can modify the embodiments of the disclosure within the scope of the technical idea of the disclosure. In addition, although an action or effect according to the configuration of the disclosure is not explicitly described while describing an embodiment of the disclosure, it is natural that even the effects predictable by the configuration should be recognized.
