[0017] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] Existing technologies for flat and curved touch displays suffer from limitations in touch and display methods, resulting in a lack of depth and immersive experience.

[0019] Therefore, this application provides a touch display component, wherein the touch display component includes, A first housing, the first housing being made of a transparent material to allow light to be transmitted, the first housing having a first opening at its bottom along a first direction, and the first housing having a first surface and a second surface respectively along its inner and outer sides along the first direction, the first surface and the second surface both being curved surfaces; A diffraction layer covering the first surface; An electrode layer, made of a transparent material, covers the second surface to form the touch interaction of the touch display assembly; An image generator is located at the bottom of the first opening along the first direction. The image generator forms a first light beam projected along the first direction. The first light beam is projected onto the diffraction layer through the first opening. The first light beam is diffracted by the diffraction layer to form a three-dimensional image.

[0020] This application also provides a method for manufacturing a touch display component, wherein the touch display component described in Example 1 is used, and the method for manufacturing the touch display component includes, A first housing is provided, the first housing being made of a transparent material to allow light to be transmitted, the first housing having a first opening at its bottom along a first direction, and the first housing having a first surface and a second surface respectively along its inner and outer sides along the first direction, the first surface and the second surface being both formed by curved surfaces; A diffraction layer is formed, which is deposited onto the first surface; An electrode layer is formed, which is deposited onto the second surface. Longitude and latitude lines are formed on the outer surface of the electrode layer by etching to divide the electrode layer into several touch areas. A protective layer is formed by deposition covering the outer surface of the electrode layer to protect the electrode layer. An image generator is formed and disposed at the bottom of the first opening along the first direction.

[0021] This application further provides a smart terminal, wherein the smart terminal includes the touch display component described in Embodiment 1, and the smart terminal is applied in an in-vehicle interactive system. Example 1: In the current field of in-vehicle interaction, flat and curved touchscreen displays dominate. Flat touchscreen displays have the advantages of simple structure and relatively low cost, and are widely used in various vehicle models. However, their touch and display methods are relatively simple and lack a sense of depth. While curved touchscreen displays improve the visual experience and increase immersion to some extent, they are essentially still a deformation of a two-dimensional plane. Their curved design is mainly to adapt to the visual curvature of the human eye and improve viewing comfort, but it does not break out of the scope of two-dimensional display. Therefore, designing a touchscreen component capable of displaying three-dimensional images is particularly important.

[0022] Please refer to the attached document. Figure 1 As shown, in this embodiment, the first direction X refers to the height direction of the touch display component 10, that is, the direction of the touch display component 10 from top to bottom or from bottom to top. In this embodiment, the image generator 500 is disposed above the first housing 100, and the first housing 100 is disposed below the image generator 500.

[0023] Appendix Figure 1 This is a schematic diagram of one structure of the touch display component 10 of this application. Please refer to the attached diagram. Figure 1As shown, the touch display component 10 of this application includes a first housing 100, which is a hollow housing structure with an internal cavity. The first housing 100 is made of transparent material to facilitate the transmission of light. A first opening 110 is provided at the bottom of the first housing 100 along the first direction X to allow light to enter the cavity. A first surface 120 and a second surface 130 are respectively provided on the inner and outer sides of the first housing 100 along the first direction X. The first surface 120 is located on the inner side of the first housing 100, and the second surface 130 is located on the outer side of the first housing 100. Both the first surface 120 and the second surface 130 are curved surfaces to facilitate the subsequent formation of a three-dimensional image.

[0024] In one embodiment, the first shell 100 is composed of a hemisphere or a superhemispherical structure, and both the first surface 120 and the second surface 130 are spherical structures. The spherical first surface 120 and the second surface 130 are merely specific implementations of the first surface 120 and the second surface 130 as curved surface structures in this embodiment. A hemisphere refers to a structure obtained by cutting a sphere along its diametrical plane; its height (radius of curvature) is equal to the radius of its base, resembling a standard "semicircle." A superhemispherical structure refers to a curved surface structure with a height greater than its base radius, typically exhibiting a "high-convex" shape extending upwards from the base and beyond the hemispherical boundary.

[0025] In one embodiment, the first housing 100 is made of glass material. Glass material is only one specific embodiment of the transparent material of the first housing 100 in this embodiment, and the transparent material in this embodiment is not limited to glass.

[0026] Please refer to the attached document. Figure 1 As shown, the touch display component 10 of this application further includes a diffraction layer 200, which covers the first surface 120. When irradiated light comes into contact with the diffraction layer 200, diffraction occurs on the first surface 120. Since the first surface 120 has a curved structure, the image ultimately forms a stereoscopic picture. Furthermore, the diffraction layer 200 is composed of titanium dioxide and silicon dioxide composites and is deposited on the first surface 120 using a magnetron sputtering process. Furthermore, the diffraction layer 200 uses its surface micro-nano structure to precisely spatially modulate the phase and amplitude of the incident light wave, causing specific interference during propagation, thereby reconstructing a preset image on a specific plane.

[0027] Please refer to the attached document. Figure 1As shown, the touch display component 10 of this application also includes an electrode layer 300, which covers the second surface 130. The electrode layer 300 has certain conductivity, so that touch interaction with the touch display component 10 can be realized through clicking or sliding operations on the electrode layer 300, thereby issuing corresponding control commands. The electrode layer 300 is made of a transparent material, which can further avoid affecting the observation of stereoscopic images.

[0028] In one embodiment, the electrode layer 300 is made of indium tin oxide (ITO). ITO is composed of indium oxide and tin oxide. Indium oxide is the main material of ITO, accounting for 90% to 95%, while tin oxide is a dopant, accounting for 5% to 10%. The electrode layer 300 is deposited on the second surface 130 using a magnetron sputtering process.

[0029] Furthermore, longitude and latitude lines are provided on the surface of the electrode layer 300 to divide the electrode layer 300 into several touch areas. The touch display component 10 memorizes the position of the touch areas to improve the accuracy of the touch display component 10 operation. The longitude and latitude lines are formed by etching.

[0030] Please refer to the attached document. Figure 1 As shown, the touch display component 10 of this application includes a protective layer 400, which covers the outer surface of the electrode layer 300 to form a protection for the electrode layer 300. The protective layer 400 is made of a rigid organic material. Furthermore, the protective layer 400 is made of a transparent material, which can further avoid affecting the viewing of stereoscopic images.

[0031] Please refer to the attached document. Figure 1 As shown, the touch display component 10 of this application also includes an image generator 500. The image generator 500 is located at the bottom of the first opening 110 along the first direction X. The image generator 500 forms a first light beam projected in the first direction X. The first light beam is projected through the first opening 110 to the diffraction layer 200. After the first light beam is diffracted by the diffraction layer 200, a stereoscopic image is formed on the first surface 120 to enhance the stereoscopic effect of the image. After cooperating with the electrode layer 300, a stereoscopic touch display is formed.

[0032] In one embodiment, the image generator 500 is an image generation unit based on laser scanning projection, namely an LBS laser projection PGU. The laser scanning-based image generation unit utilizes the excellent collimation of lasers and the vector scanning mechanism of MEMS, abandoning the traditional projection "image first, then projection" lens focusing mode. Instead, it uses the laser as an "electronic paintbrush" to directly draw point by point on the diffraction layer 200. Since each pixel is a self-illuminating point generated by the laser directly acting on the diffraction layer 200, rather than an image relying on lens convergence, there is no fixed focal plane limitation. Regardless of the distance between points on the surface of the diffraction layer 200, wherever the beam hits, that is the focal point, thus achieving clear, focus-free imaging across the entire area.

[0033] Example 2: This embodiment discloses a method for fabricating a touch display component 10, which is applied to the touch display component 10 in Embodiment 1. The fabrication method of the touch display in this embodiment includes the fabrication of a touch display unit and the fabrication of an image generator 500, and the fabrication of the touch display unit and the fabrication of the image generator 500 are carried out concurrently.

[0034] The manufacturing process of a touch display unit includes the following steps: Step 1: Provide a first housing 100. The first housing 100 is made of transparent material to allow light to be transmitted. The first housing 100 has a first opening 110 at its bottom along the first direction X. The first housing 100 has a first surface 120 and a second surface 130 on its inner and outer sides along the first direction X, respectively. Both the first surface 120 and the second surface 130 are made of curved surfaces. Step 2: Forming a diffraction layer 200, which covers the first surface 120 by deposition; Step 3: Forming electrode layer 300, which covers the second surface 130 by deposition; Step 4: Form longitude and latitude lines on the outer surface of electrode layer 300. The longitude and latitude lines are formed by etching to divide electrode layer 300 into several touch areas. Step 5: Forming a protective layer 400. The protective layer 400 is deposited on the outer surface of the electrode layer 300 to protect the electrode layer 300.

[0035] The creation of image generator 500 includes the following steps: Step 1: Form an image generator 500 by setting the image generator 500 at the bottom of the first opening 110 along the first direction X.

[0036] In one embodiment, the diffraction layer 200, the electrode layer 300, and the protective layer 400 are all deposited by magnetron sputtering.
