[0048] Embodiments of the present application will be described in detail below, the embodiments described with reference to the drawings are exemplary, and the embodiments of the present application will be described in detail below.
[0049] The embodiments of the present application will be described below with reference to Figures 1-7The image production device 100 of the head-up display device according to the embodiments of the present application is described, and the image production device 100 of the head-up display device in the embodiments of the present application can be applied to the head-up display device 1000, and the head-up display device 1000 can be applied to vehicles, but is not limited thereto.
[0050] In combination Figures 2-7 As shown in the figure, the image production device 100 of the head-up display device according to the embodiments of the present application can mainly include: a shell 10, a light-emitting chip assembly 20, a display piece 30 and a light refraction piece 40, wherein the display piece 30 and the light refraction piece 40 are both arranged in the shell 10, so that the display piece 30 and the light refraction piece 40 can be protected from external force impact to avoid damage. The display piece 30 is located on the light-emitting side of the light-emitting chip assembly 20, so that the light emitted by the light-emitting chip assembly 20 can propagate towards the display piece 30.
[0051] Further, the display piece 30 includes a first display piece 31 and a second display piece 32, and the shell 10 is provided with a partition plate 11 between the first display piece 31 and the second display piece 32, which not only can support the first display piece 31 and the second display piece 32, but also can separate the first display piece 31 and the second display piece 32, so that the image area displayed by the first display piece 31 and the image area displayed by the second display piece 32 can be independent of each other, and the light propagating to the first display piece 31 and the light propagating to the second display piece 32 can be prevented from crossing and mixing.
[0052] Further, the light refraction piece 40 is arranged between the light-emitting side of the light-emitting chip assembly 20 and the display piece 30, so as to refract the light emitted by the light-emitting chip assembly 20 during the propagation process to the display piece 30, which can change the propagation direction of the light emitted by the light-emitting chip assembly 20, so that the light can propagate in the correct direction.
[0053] Further, the light refraction piece 40 includes a first light refraction piece 41 and a second light refraction piece 42, and the partition plate 11 extends between the first light refraction piece 41 and the second light refraction piece 42 to separate the light in the first light refraction piece 41 area and the light in the second light refraction piece 42 area, which can prevent the first light refraction piece 41 and the second light refraction piece 42 from crossing and mixing.
[0054] Further, the first light refraction piece 41 corresponds to the first display piece 31, so that the light rays refracted by the first light refraction piece 41 propagate vertically to the first display piece 31, and the second light refraction piece 42 corresponds to the second display piece 32, so that the light rays refracted by the second light refraction piece 42 propagate vertically to the second display piece 32. In this way, the light rays emitted by the light-emitting chip assembly 20 are refracted by the light refraction piece 40 and then emitted to the display piece 30, which can solve the problem of light loss and waste caused by separating light rays by a light separation plate or a light shield cover in the prior art, thereby improving the utilization rate of light rays.
[0055] In the embodiment of the present application, the refraction angle and the refractive index of the first light refraction piece 41 are different from those of the second light refraction piece 42, so that the images displayed by the first display piece 31 and the images displayed by the second display piece 32 can realize two kinds of imaging of far view and near view, and a virtual image design with a large field of view can be realized.
[0056] Therefore, by arranging the first light refraction piece 41 to correspond to the first display piece 31 and arranging the second light refraction piece 42 to correspond to the second display piece 32, the first display piece 31 can display the light rays emitted by the light-emitting chip assembly 20 after being refracted by the first light refraction piece 41, and the second display piece 32 can display the light rays emitted by the light-emitting chip assembly 20 after being refracted by the second light refraction piece 42. In this way, the near view display area and the far view display area can be formed by the display piece 30 respectively, and the problem of light loss and waste caused by separating light rays in the prior art can be solved, thereby improving the utilization rate of light rays and realizing a virtual image design with a large field of view.
[0057] According to the embodiment of the present application, the light refraction piece 40 is at least one of a prism, a lens, a polarizing film and a grating. Specifically, the main functions of the prism include refracting light rays, reflecting light rays and dispersing light rays, and the prism can be used as the light refraction piece 40 in the present application to refract the light emitted by the light-emitting chip assembly 20 to the display piece 30.
[0058] Further, the lens is usually made of glass or plastic and has at least one curved surface for focusing or dispersing light rays. The working principle of the lens is based on the refraction law of light, that is, when light rays enter from one medium to another medium (such as from air to glass), the propagation direction of the light rays will change. Therefore, the lens can be used as the light refraction piece 40 in the present application to refract the light emitted by the light-emitting chip assembly 20 to the display piece 30.
[0059] Further, the polarizing film is based on the wave nature and polarization phenomenon of light, and only allows light waves in a certain direction to pass through. Therefore, the polarizing film can be used as the light refraction piece 40 in the present application to refract the light emitted by the light-emitting chip assembly 20 to the display piece 30.
[0060] Further, the grating disperses and controls the behavior of light by means of diffraction and interference. The grating is usually composed of a series of very close equidistant parallel grooves or trenches, and each groove can be regarded as a new light source when the light irradiates on the grating. The secondary waves emitted by each groove interfere with each other to produce diffraction phenomenon, so that the light emitted by the light-emitting chip assembly 20 can propagate in the direction of the display piece 30. Therefore, the grating can be used as the light folding piece 40 in the utility model.
[0061] In combination Figures 2-4 As shown in the figure, the image production device 100 of the head-up display device further comprises an imaging piece 50, which is arranged between the light-emitting side of the light-emitting chip assembly 20 and the display piece 30. Specifically, the imaging piece 50 is used for capturing or displaying images. In the embodiment of the utility model, the display piece 30 is an imaging film, which has special optical properties and can change the direction, intensity or color of light, so as to improve the visual effect and user experience. The imaging piece 50 is arranged between the light-emitting side of the light-emitting chip assembly 20 and the display piece 30, so that the imaging piece 50 can finally present the light emitted by the light-emitting chip assembly 20 on the display piece 30 in the form of an image, and reflect to the eyebox 500.
[0062] In the embodiment of the utility model, the imaging piece 50 is a lens group. Specifically, a plurality of lenses are combined into a lens group, which can realize specific optical functions or improve imaging quality, and can effectively correct aberration and improve image clarity. In the embodiment of the utility model, the lens group is used as the imaging piece, which can improve the visual effect and user experience.
[0063] In some embodiments of the utility model, in combination Figure 2 and Figure 3 As shown in the figure, the imaging piece 50 is arranged between the light-emitting side of the light-emitting chip assembly 20 and the light folding piece 40, so that the light emitted by the light-emitting chip assembly 20 can first pass through the imaging piece 50, then pass through the light folding piece 40, and finally reach the display piece 30. Such an arrangement can ensure that the required image is finally displayed on the display piece 30.
[0064] In still some embodiments of the utility model, in combination Figure 4 As shown in the figure, the imaging piece 50 is arranged between the light folding piece 40 and the display piece 30, so that the light emitted by the light-emitting chip assembly 20 can first pass through the light folding piece 40, then pass through the imaging piece 50, and finally reach the display piece 30. Such an arrangement can also ensure that the required image is finally displayed on the display piece 30, and the close-up image area and the long shot image area are imaged respectively.
[0065] In some embodiments of the utility model, in combination Figure 3 and Figure 4As shown, the imaging member 50 is arranged in the housing 10, the imaging member 50 comprises a first imaging member 51 and a second imaging member 52, and the partition plate 11 is at least partially located between the first imaging member 51 and the second imaging member 52. Specifically, the housing 10 can protect the imaging member 50 from external force impact to avoid damage. In order to realize the near image area and the far image area on the display member 30, the imaging member 50 is arranged to comprise the first imaging member 51 and the second imaging member 52, and the first imaging member 51 and the second imaging member 52 are separated by the partition plate 11 to prevent the first imaging member 51 and the second imaging member 52 from cross light mixing, so that the utilization rate of light can be improved, so that the near image area and the far image area can be displayed on the display member 30 respectively, thereby realizing the virtual image design of a large field of view.
[0066] In some other embodiments of the present application, in combination with Figure 2 As shown, the imaging member 50 can be arranged outside the housing 10 and spaced apart from the housing 10, so that the imaging member 50 is exposed outside the housing 10, which can facilitate the arrangement of the imaging member 50 in the image production device 100 of the head-up display device, and facilitate the maintenance and replacement of the imaging member 50.
[0067] In the embodiments of the present application, the technology adopted by the light-emitting chip assembly 20 includes but is not limited to at least one of DLP (Digital Light Processing), LCoS (Liquid Crystal On Silicon) and LBS (Laser Beam Scanning).
[0068] Specifically, the key of DLP lies in a digital micromirror chip. Millions of micro lenses are integrated on the digital micromirror chip, which can accurately control the light emitted by the light source, and form an image on the diffusion sheet through a projection lens.
[0069] LCoS uses a special CMOS (Complementary Metal-Oxide-Semiconductor) integrated circuit chip, and the chip is coated with liquid crystal silicon. By utilizing the optical properties of liquid crystal and the electrical properties of silicon chip, LCOS (Liquid Crystal on Silicon) can accurately control the direction and intensity of light propagation, thereby generating clear and vivid images.
[0070] LBS is a "MEMS (Micro-Electro-Mechanical Systems) micro-laser projection" solution. It uses an RGB laser module to emit red, green, and blue light, which is mixed by a lens and then projected onto a tiny MEMS micromirror. This micromirror rotates under the drive of an actuator, thereby scanning and forming an image. RGB is a color model representing the three primary colors of red, green, and blue. In this model, almost all visible colors can be obtained by mixing these three colors in different proportions.
[0071] According to the embodiments of this utility model, in conjunction with Figures 5-7 As shown, the image production apparatus 100 of the head-up display device also includes a shaping component 60, which is spaced between the light-emitting side of the light-emitting chip assembly 20 and the display component 30, which is a liquid crystal display screen. Specifically, the shaping component 60 can be used to change the shape or distribution of the light beam, thereby adjusting the light beam to meet the needs of a specific application, such as shaping a non-uniform light beam into a uniform light spot, or changing the size and divergence angle of the light beam. This invention, by placing the shaping component 60 between the light-emitting side of the light-emitting chip assembly 20 and the display component 30, can shape the emitted light from the light-emitting chip assembly 20 to present the graphics required by the device on the display component 30. These graphics can then be used to display the information to be shown on the display component 30 for user observation.
[0072] In some embodiments of this invention, the shaping element 60 is at least one of a reflector, a Fresnel lens, a diffuser, and a brightness enhancement film. Specifically, the reflector can effectively collect light emitted from the light-emitting chip assembly 20 and guide the light in a specific direction, thereby improving light utilization efficiency and enhancing the lighting effect. In this embodiment of the invention, the use of a reflector as the shaping element 60 can improve the utilization rate of light emitted from the light-emitting chip assembly 20, which is beneficial for enhancing the brightness of the graphic display area.
[0073] Furthermore, Fresnel lenses can effectively focus or disperse light, and compared to traditional lenses, they are lighter and thinner. In this embodiment of the invention, a Fresnel lens is used as the shaping component 60, which not only increases the display clarity of the graphic area on the display component 30, but also helps to reduce the weight of the image production device 100 of the head-up display device, and thus helps to reduce the size of the image production device 100 of the head-up display device.
[0074] Further, the diffusion plate reduces the directivity of light by scattering light rays, which can make the light rays more evenly distributed on the display 30, which can avoid bright spots or shadow areas in the graphical display area, and thus can improve the visual comfort and aesthetics. In the embodiments of the present application, the diffusion plate is used as the shaping piece 60, which can make the graphical brightness displayed on the display 30 more uniform, and the display effect of the graphics can be adjusted by setting the light transmittance and haze value of the diffusion plate.
[0075] Further, the brightness enhancement film can direct the light rays emitted by the directional backlight, which can make more light rays emitted towards the graphical display area, which can significantly improve the brightness and contrast of the graphical display on the display 30 without increasing energy consumption. In the embodiments of the present application, the brightness enhancement film is used as the shaping piece 60, which can increase the brightness of the graphics on the display device, so that the user can better observe the graphics displayed by the device, and the display effect of the graphics and the user experience can be improved.
[0076] In some embodiments of the present application, as shown in Figure 5 and Figure 6 , the shaping piece 60 is arranged between the light-emitting side of the light-emitting chip assembly 20 and the light folding piece 40, which can make the light rays emitted by the light-emitting chip assembly 20 first pass through the shaping piece 60, then pass through the light folding piece 40, and finally reach the display 30. Such an arrangement can ensure that the near and far graphics displayed on the display 30 are clearer.
[0077] In some embodiments of the present application, as shown in Figure 7 , the shaping piece 60 is arranged between the light folding piece 40 and the display 30, which can make the light rays emitted by the light-emitting chip assembly 20 first pass through the light folding piece 40, then pass through the shaping piece 60, and finally reach the display 30. Such an arrangement can ensure that the near and far graphics displayed on the display 30 are clearer.

Specifically, the shell 10 can protect the shaping piece 60 from external force impact to avoid damage. In order to improve the graphic clarity and brightness of both the close-range image area and the long-range image area on the display piece 30, the shaping piece 60 is arranged to include the first shaping piece 61 and the second shaping piece 62, and the first shaping piece 61 and the second shaping piece 62 are separated by the partition plate 11 to prevent cross-mixed light from the first shaping piece 61 and the second shaping piece 62, so that the utilization rate of light can be improved, and the close-range image and the long-range image displayed by the display piece 30 can be clearer and brighter, thereby ensuring that the image production device 100 of the head-up display device is clearer and brighter in imaging under the design requirement of a large field of view.
[0079] In some other embodiments of the present application, the shaping piece 60 can be arranged outside the shell 10 and spaced apart from the shell 10, so that the shaping piece 60 is exposed outside the shell 10, which can facilitate the arrangement of the shaping piece 60 in the image production device 100 of the head-up display device and the maintenance and replacement of the shaping piece 60.
[0080] In the embodiments of the present application, the light-emitting chip assembly 20 is arranged with a backlight panel including at least one of, but not limited to, an LED (Light Emitting Diode) and a Mini-LED.
[0081] According to the embodiments of the present application, the shell 10 is provided with a clamping portion, and the display piece 30 is detachably clamped and matched with the clamping portion. Specifically, the clamping structure can reliably connect the display piece 30 with the shell 10, and the operation is convenient, which not only ensures the stability of the arrangement of the display piece 30 in the shell 10, but also facilitates the assembly, maintenance and replacement of the image production device 100 of the head-up display device.
[0082] In the embodiments of the present application, the shell 10 is made of a heat-conducting material, including at least one of, but not limited to, aluminum, copper and aluminum alloy, which is conducive to the heat dissipation of the image production device 100 of the head-up display device.

[0084] Specifically, the light-emitting chip piece 21 is electrically connected with the circuit board 22, so that the light emitted by the light-emitting chip piece 21 can be controlled to make the image production device 100 of the head-up display device produce a required pattern, and then the required information can be transmitted to the user through the pattern.
[0085] Further, the light folding piece 40 is arranged between the light-emitting side of the light-emitting chip piece 21 and the display piece 30, and the light folding piece 40 is arranged to be spaced apart from the light-emitting side of the light-emitting chip piece 21 and the display piece 30, so that the light emitted by the light-emitting chip piece 21 can be transmitted to the light folding piece 40, and then transmitted to the display piece 30 after being folded by the light folding piece 40, so as to ensure normal transmission of the light in the image production device 100 of the head-up display device.
[0086] Further, the circuit board 22 is arranged on the side of the light-emitting chip piece 21 away from the light folding piece 40, so as to not only ensure electrical connection between the circuit board 22 and the light-emitting chip piece 21, but also allow the circuit board 22 to avoid the light-emitting side of the light-emitting chip piece 21, thereby ensuring normal transmission of the light emitted by the light-emitting chip piece 21 in the image production device 100 of the head-up display device.
[0087] In some embodiments of the present application, as shown in Figures 2-4 As shown in FIG. 1, the light-emitting chip assembly 20 can be arranged outside the shell 10 and spaced apart from the shell 10, so that the light-emitting chip assembly 20 can be exposed outside the shell 10, and the arrangement of the light-emitting chip assembly 20 in the image production device 100 of the head-up display device can be facilitated, and the maintenance and replacement of the light-emitting chip assembly 20 can be facilitated.
