[0053] Some embodiments of the present invention will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0054] Embodiment

[0055] Refer to Figure 1 , this embodiment provides a display device 200. The display device 200 includes an optical component 100 and a lens 210, and the optical component 100 is disposed on one side of the lens 210. Among them, the display device 200 can be a head-mounted display device such as a VR glasses, an AR glasses, or an MR glasses. The specific type of the head-mounted display device is not limited in this application.

[0056] Please refer to Figure 2, the optical component 100 includes a liquid crystal lens module 10, a first transparent substrate 20, and a liquid crystal color-changing module 30. The liquid crystal lens module 10 is disposed on one side of the first transparent substrate 20, and the liquid crystal lens module 10 can adjust its diopter based on the change of its externally applied electric field. A liquid crystal molecular material is provided in the liquid crystal lens module 10. By changing the voltage at both ends of the liquid crystal lens module 10 through an externally applied electric field, the arrangement of liquid crystal molecules in the liquid crystal lens module 10 is adjusted, so as to achieve the purpose of changing the diopter of the liquid crystal lens module 10. The liquid crystal color-changing module 30 is disposed on the other side of the first transparent substrate 20 away from the liquid crystal lens module 10. The liquid crystal color-changing module 30 includes a first electrode structure 31 and a liquid crystal color-changing component 32. The first electrode structure 31 is configured to form a first electric field, and the liquid crystal color-changing component 32 is located in the first electric field and is configured to adjust the state of its liquid crystal molecules with the change of the first electric field. The liquid crystal color-changing component 32 is also provided with a liquid crystal molecular material. Similarly, since the liquid crystal color-changing component 32 is located in the first electric field, the light transmittance of the liquid crystal color-changing component 32 can be adjusted by changing the first electric field. In this embodiment, the liquid crystal lens module 10 is located on the side of the first transparent substrate 20 close to the user, and the liquid crystal color-changing module 30 is located on the side of the first transparent substrate 20 away from the user. The first transparent substrate 20 can be a transparent resin sheet or glass, and its shape can be planar or curved, which can be set according to the actual process requirements of the optical component 100.

[0057] For the optical component 100 of the present application, on the one hand, by providing the liquid crystal lens module 10 and the liquid crystal color-changing module 30 containing liquid crystal molecular materials, the light transmittance of the optical component 100 can be changed by controlling the voltage passing through the liquid crystal color-changing component 32 through the first electric field, thereby reducing the brightness of the ambient light source entering the user's line of sight. On the other hand, by controlling the voltage passing through the liquid crystal lens module 10 through an externally applied electric field, the focusing distance of the optical component 100 is adjusted, so that the optical component 100 can meet the myopia or hyperopia degrees of different users. On the further hand, the liquid crystal lens module 10 and the liquid crystal color-changing module 30 share the first transparent substrate 20, which can reduce the thickness of the overall optical component 100.

[0058] Further, the first electrode structure 31 includes a first transparent conductive layer 311 and a second transparent conductive layer 312. The first transparent conductive layer 311 and the second transparent conductive layer 312 are opposite and spaced apart. A first electric field is formed between the first transparent conductive layer 311 and the second transparent conductive layer 312. The liquid crystal color-changing component 32 is located between the first transparent conductive layer 311 and the second transparent conductive layer 312. In this embodiment, the first transparent conductive layer 311 and the second transparent conductive layer 312 can be ITO electrode layers.

[0059] In some embodiments, the liquid crystal color-changing module 30 further includes a first power supply structure 33. The first power supply structure 33 is electrically connected to the first transparent conductive layer 311 and the second transparent conductive layer 312. A circuit loop is formed among the first power supply structure 33, the first transparent conductive layer 311, and the second transparent conductive layer 312. By changing the voltage of the first power supply structure 33, the first electric field is changed, so as to adjust the state of the liquid crystal molecules in the liquid crystal color-changing module 30.

[0060] Please also combine with Figure 2 , the optical component 100 further includes a second transparent substrate 40, and the second transparent substrate 40 is located on the side of the liquid crystal color-changing component 32 away from the first transparent substrate 20. The liquid crystal color-changing component 32 includes a first alignment film 321, a liquid crystal color-changing layer 322, and a second alignment film 323 which are stacked in sequence. The first alignment film 321 is adjacent to the first transparent conductive layer 311. The liquid crystal color-changing layer 322 is made of a liquid crystal molecular material. Among them, the liquid crystal molecules include nematic liquid crystals or smectic liquid crystals.

[0061] As Figure 3 The nematic liquid crystal in has an ionic part and a hole part in the liquid crystal molecule itself. By adjusting the voltage at both ends of the nematic liquid crystal, the transfer of electrons between the ionic part and the hole part can be controlled, so as to achieve the effect of changing the color.

[0062] As Figure 4 The smectic liquid crystal in determines whether light can penetrate the liquid crystal color-changing component 32 by controlling the arrangement of the liquid crystal molecules. When the liquid crystal molecules are arranged disorderly, the light will be scattered when penetrating, resulting in a decrease in the light transmittance of the liquid crystal color-changing component 32. When the liquid crystal molecules are arranged orderly, the light can normally penetrate the liquid crystal color-changing component 32, and the light transmittance of the liquid crystal color-changing component 32 is higher.

[0063] A liquid crystal molecular material is filled between the relatively spaced first alignment film 321 and the second alignment film 323. By adjusting the voltage on both sides of the liquid crystal color-changing component 32, the liquid crystal molecules are caused to move, so as to change the amount of light passing through the liquid crystal color-changing component 32, and the purpose of adjusting different light transmittances of the optical component 100 is achieved.

[0064] In some embodiments, as Figure 5 shown, the liquid crystal color-changing component 32 can be a liquid crystal electro-optic dimming film 34. In this embodiment, the liquid crystal electro-optic dimming film 34 injects a liquid crystal or polymer hybrid material between two transparent conductive films. This structure allows the liquid crystal electro-optic dimming film 34 to be in an opaque state without the action of an electric field, and when an alternating current is applied, the liquid crystal molecules are arranged orderly, so that the liquid crystal electro-optic dimming film 34 is converted from an opaque state to a transparent state.

[0065] Specifically, the polymer in the liquid crystal electro-control dimming film 34 includes one or more of polyethylene terephthalate, polymethyl methacrylate, or silica gel. The liquid crystal molecules in the liquid crystal electro-control dimming film 34 include one or more of cholesteryl esters, fluorinated esters, 4'-n-pentyl-4-cyanobiphenyl, or 4-heptyl-4'-cyanobiphenyl.

[0066] By adjusting the voltage across the liquid crystal electro-control dimming film 34, the liquid crystal molecules in the liquid crystal electro-control dimming film 34 can be switched back and forth between an ordered arrangement and a disordered arrangement, so as to achieve the purpose that light can pass through the liquid crystal electro-control dimming film 34 or light cannot pass through the liquid crystal electro-control dimming film 34. The optical component 100 in this embodiment can select to use the liquid crystal color-changing component 32 or the liquid crystal electro-control dimming film 34 according to actual design requirements.

[0067] The liquid crystal color-changing component 32 in this application contains liquid crystal molecular materials, or the liquid crystal electro-control dimming film 34 is used to replace the liquid crystal color-changing component 32. Compared with the electrochromic layer in the prior art, which controls the movement of ions between the electrochromic layer, the electrolyte layer, and the ion storage layer by applying an electric field, since the ion volume is large and the movement path is long, the color-changing time will be relatively long. In the liquid crystal color-changing component 32 in this application, electrons transfer between molecules in the liquid crystal layer, and the liquid crystal electro-control dimming film 34 controls the simple rotation of the liquid crystal molecules themselves. Therefore, the liquid crystal color-changing layer 322 or the liquid crystal electro-control dimming film 34 has a faster color-changing speed and more color-changing times than the electrochromic layer in the prior art. At the same time, the electrochromic layer in the prior art includes three layers: an electrochromic layer, an electrolyte layer, and an ion storage layer, while the liquid crystal electro-control dimming film 34 only includes one layer. Although the liquid crystal color-changing component 32 includes three layers, the thicknesses of the first alignment film 321 and the second alignment film 323 are very thin compared to other layers and can be ignored. Therefore, the liquid crystal color-changing component 32 or the liquid crystal electro-control dimming film 34 also has a smaller thickness than that of using an electrochromic layer, enabling the subsequent thin and light design of the optical component 100 to be completed.

[0068] In some embodiments, please refer to Figure 2 again. The liquid crystal lens module 10 includes a second electrode structure 11 and a liquid crystal lens assembly 12. The second electrode structure 11 is configured to form a second electric field, and the liquid crystal lens assembly 12 is located within the second electric field and is configured to adjust its diopter according to the change of the second electric field.

[0069] Specifically, a third transparent substrate 14 is further provided on the side of the second electrode structure 11 away from the first transparent substrate 20. The first transparent substrate 20 and the third transparent substrate 14 are used to fix the liquid crystal lens module 10. The second electrode structure 11 includes a third transparent conductive layer 111 and a fourth transparent conductive layer 112, and the third transparent conductive layer 111 and the fourth transparent conductive layer 112 are opposite and spaced apart. A second electric field is formed between the third transparent conductive layer 111 and the fourth transparent conductive layer 112, and the liquid crystal lens assembly 12 is located between the third transparent conductive layer 111 and the fourth transparent conductive layer 112. In this embodiment, the third transparent conductive layer 111 and the fourth transparent conductive layer 112 may also be ITO electrode layers.

[0070] In some embodiments, the liquid crystal lens module 10 further includes a second power supply structure 13. The second power supply structure 13 is electrically connected to the third transparent conductive layer 111 and the fourth transparent conductive layer 112. The second power supply structure 13, the third transparent conductive layer 111 and the fourth transparent conductive layer 112 together form a circuit loop. The liquid crystal lens assembly 12 includes a third alignment film 121, a liquid crystal lens layer 122 and a fourth alignment film 123 which are sequentially stacked, and the third alignment film 121 is adjacent to the third transparent conductive layer 111. The liquid crystal lens layer 122 has liquid crystal molecules. By changing the voltage of the second power supply structure 13, the second electric field is adjusted to change the arrangement direction of the liquid crystal molecules in the liquid crystal lens layer 122, so that the light has different refractive indexes when passing through the liquid crystal lens module 10, and thus the optical effect equivalent to that of a convex lens or a concave lens is achieved.

[0071] In some embodiments, the first power supply structure 33 and the second power supply structure 13 may be two independent power supplies to supply power to the first electrode structure 31 and the second electrode structure 11 respectively.

[0072] It can be understood that, in other embodiments, the first power supply structure 33 and the second power supply structure 13 are coupled to a power supply in the form of a power supply loop, and the power supply supplies power to the first electrode structure 31 and the second electrode structure 11 through the first power supply structure 33 and the second power supply structure 13 at the same time.

[0073] In other embodiments, the first transparent conductive layer 311 is electrically connected to the fourth transparent conductive layer 112, so that the liquid crystal lens module 10 and the liquid crystal color change module 30 simultaneously use the first transparent conductive layer 311 and the fourth transparent conductive layer 112 as a common positive electrode or use the first transparent conductive layer 311 and the fourth transparent conductive layer 112 as a common negative electrode. In some embodiments, the thickness range of the liquid crystal color change layer 322 is 1um - 50um. For example, the thickness of the liquid crystal color change layer 322 may be 10um, 25um, 30um or 45um.

[0074] The thickness range of the liquid crystal lens layer 122 is 10um - 200um. For example, the liquid crystal lens layer 122 can be 15um, 20um, 130um, or 185um.

[0075] The thickness ranges of the first transparent conductive layer 311, the second transparent conductive layer 312, the third transparent conductive layer 111, and the fourth transparent conductive layer 112 are all 50nm–500nm. The thicknesses of the first transparent conductive layer 311, the second transparent conductive layer 312, the third transparent conductive layer 111, and the fourth transparent conductive layer 112 can be the same, different from each other, or partially the same. For example, the thicknesses of the first transparent conductive layer 311, the second transparent conductive layer 312, the third transparent conductive layer 111, and the fourth transparent conductive layer 112 can be 60nm, 150nm, 300nm, or 450nm. Or, the thicknesses of the first transparent conductive layer 311 and the second transparent conductive layer 312 can be 160nm, 250nm, 290nm, or 400nm, and the thicknesses of the third transparent conductive layer 111 and the fourth transparent conductive layer 112 can both be 190nm, 220nm, 390nm, or 420nm.

[0076] The thickness ranges of the first alignment film 321, the second alignment film 323, the third alignment film 121, and the fourth alignment film 123 are all 10nm–500nm. The thicknesses of the first alignment film 321, the second alignment film 323, the third alignment film 121, and the fourth alignment film 123 can be the same, different from each other, or partially the same. For example, the thicknesses of the first alignment film 321, the second alignment film 323, the third alignment film 121, and the fourth alignment film 123 can all be 20nm, 130nm, 310nm, or 410nm. Or, the thicknesses of the first alignment film 321 and the second alignment film 323 can be 60nm, 150nm, 190nm, or 300nm, and the thicknesses of the third alignment film 121 and the fourth alignment film 123 can be 130nm, 350nm, 390nm, or 480nm.

[0077] According to the actual thickness design requirements of the optical component 100, the thicknesses of the liquid crystal lens layer 122, the first transparent conductive layer 311, the second transparent conductive layer 312, the third transparent conductive layer 111, the fourth transparent conductive layer 112, the first alignment film 321, the second alignment film 323, the third alignment film 121, and the fourth alignment film 123 can be adjusted to meet the design requirements of different thicknesses of the optical component 100.

[0078] In some embodiments, please refer to Figure 5, the first transparent substrate 20 and / or the third transparent substrate 14 may be provided with an optical waveguide structure (not shown in the figure). The optical waveguide structure may be a grating structure, which enables light to be refracted multiple times within the first transparent substrate 20 and / or the third transparent substrate 14 and then propagate substantially in one direction. The grating structure may be a binary grating, a two-dimensional grating or an inclined grating. The optical waveguide structure has the advantages of not blocking the user's line of sight, increasing the range of the moving eye socket, and being beneficial to improving the appearance of the optical component 100.

[0079] Figures 2 to 5 For the optical component 100 shown, a liquid crystal lens module 10 and a liquid crystal color-changing module 30 are respectively arranged on opposite sides of the first transparent substrate 20. On the one hand, a liquid crystal color-changing layer 322 is arranged between the first alignment film 321 and the second alignment film 323 which are oppositely arranged in the liquid crystal color-changing module 30. By controlling the voltage across the liquid crystal color-changing component 32 through the first transparent conductive layer 311, the second transparent conductive layer 312 and the first power supply structure 33, the light transmittance of the optical component 100 can be changed and the brightness of the ambient light entering the user's line of sight can be reduced. On the other hand, a liquid crystal lens module 10 is arranged on one side of the liquid crystal color-changing module 30, and the focusing distance of the optical component 100 is adjusted by controlling the voltage across the liquid crystal lens module 10, so that the optical component 100 can conform to the myopia or hyperopia degrees of different users. It solves the problems of the existing head-mounted display device, such as the increased cost caused by configuring different components according to the different myopia or hyperopia degrees of different users, the cumbersome steps caused by replacing components, and the poor brightness of the head-mounted display device when the outdoor light is strong.

[0080] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the above preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
