Description

Technical Field

[0001] This application belongs to the field of display technology, and more specifically, relates to a display panel and a display device. Background Technology

[0002] 3D display panels simulate the parallax principle of the human eye to present a stereoscopic visual effect without the need for auxiliary devices, providing users with an immersive 3D experience. To be compatible with both 3D and 2D display modes, the display panel needs to be able to switch between them. However, display panels in related technologies do not facilitate switching between 2D and 3D display modes. Summary of the Invention

[0003] The purpose of this application is to provide a display panel and a display device to solve the technical problem that the display panel in the prior art is not convenient to switch between 2D display mode and 3D display mode.

[0004] In a first aspect, embodiments of this application provide a display panel.

[0005] The display panel provided in this application embodiment includes a display module and a refractive module stacked along a first direction, wherein the refractive module is disposed on the light-emitting side of the display module; the refractive module has at least one inner cavity, and each inner cavity has at least one lens, the lens comprising a first material having a first refractive index; the inner cavity is used to contain at least one of a first fluid and a second fluid, the first fluid and the second fluid being immiscible, the refractive index of the first fluid being the same as the refractive index of the first material, and the refractive index of the second fluid being different from the first refractive index; the refractive module further includes a liquid storage component and a driving component, the liquid storage component having a liquid storage chamber communicating with the inner cavity, the driving component being used to drive either the first fluid or the second fluid in any of the inner cavities into the liquid storage chamber; when either the first fluid or the second fluid enters the liquid storage chamber, the other of the first fluid and the second fluid in the liquid storage chamber flows from the liquid storage chamber into the inner cavity and at least immerses the first material.

[0006] The beneficial effects of the display panel provided in this application embodiment are as follows: The display panel provided in this application embodiment adjusts the distribution of the first fluid and the second fluid in the inner cavity through the liquid storage component. When the first fluid immerses the lens, the combination of the first fluid and the lens does not produce a refraction effect on the light transmitted through the lens, thus realizing 2D display. When the second fluid immerses the lens, the light transmitted through the lens is refracted at the interface between the second fluid and the lens and deflected to both sides. The two deflected light rays enter the user's eyes respectively to realize 3D display. By adjusting the distribution of the first fluid and the second fluid in the inner cavity through the liquid storage component, the switching between 2D display mode and 3D display mode can be realized. Compared with the prior art, which achieves the switching between 2D display mode and 3D display mode by changing the lens structure of the display panel, the display panel provided in this application can achieve the switching between 2D display mode and 3D display mode by driving the fluid flow, which has the advantage of being easy to switch between 2D display mode and 3D display mode.

[0011] Optionally, the driving component is used to provide a first force to the reservoir and / or the inner cavity, the first force being used to drive the first fluid or the second fluid to flow directionally between the reservoir and the inner cavity.

[0012] Optionally, if the driving assembly does not provide the first force to the reservoir and / or the inner cavity, the first fluid and the second fluid are separated in the inner cavity, wherein the first fluid is away from the display module and submerges the first material, and the second fluid is located on the side of the first material closer to the display module;

[0016] Optionally, one of the first fluid and the second fluid comprises polar molecules, and the other of the first fluid and the second fluid comprises nonpolar molecules.

[0017] The driving component is used to apply an electric field to the liquid storage cavity or the inner cavity, the electric field interacting with the polar molecules to generate the first force.

[0018] Optionally, the driving component includes a first electrode and a second electrode disposed opposite to each other along the first direction.

[0019] Wherein, the first electrode is located on the inner wall of the liquid storage cavity on the side away from the display module in the first direction, and the second electrode is located on the inner wall of the liquid storage cavity on the side close to the display module in the first direction. The first electrode and the second electrode are used to generate an electric field in the liquid storage cavity.

[0020] Alternatively, the first electrode is located on the inner wall of the cavity on the side away from the display module in the first direction, and the second electrode is located on the inner wall of the cavity on the side close to the display module in the first direction. The first electrode and the second electrode are used to generate an electric field in the cavity.

[0021] Optionally, the refractive module further includes a first cover plate and a second cover plate arranged parallel to each other and spaced apart along the first direction.

[0041] 3D display panels simulate the parallax principle of the human eye to present a stereoscopic visual effect without the need for auxiliary devices, providing users with an immersive three-dimensional experience. In order to be compatible with 3D and 2D display modes, the display panel needs to be able to switch between 3D and 2D display modes.

[0042] However, the display panels in related technologies are limited by hardware structure, technical cost, compatibility, system complexity and user experience requirements, making it inconvenient to switch between 2D display mode and 3D display mode.

[0043] To address the aforementioned technical problems, embodiments of this application provide a display panel and a display device using the display panel. The display panel provided in this application embodiment can be any one of an Organic Light-Emitting Diode (OLED) display panel, a Micro Light-Emitting Diode (MicroLED / μLED) display panel, a Light Emitting Diode Panel (LED) display panel, or a Liquid Crystal Display (LCD) display panel. The display device provided in this application embodiment can be a mobile phone, television, tablet computer, laptop computer, desktop computer, in-vehicle display terminal, wearable device, advertising display device, etc.

[0044] The display device provided in this application embodiment has a refractive module on the light-emitting side of the light-emitting layer. The refractive module has an inner cavity, and a lens is provided in the inner cavity. The liquid storage component is connected to the inner cavity. The lens is immersed by driving a first fluid or a second fluid through the liquid storage component, so that the display panel can switch between 3D display mode and 2D display mode. Compared with the display panel in the related technology, which needs to change the mechanical structure inside the panel to adjust the display mode, the display device provided in this application embodiment has the advantages of simple structure and faster speed by driving fluid movement to adjust the display mode.

[0045] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 The display panel 100 provided in the embodiments of this application will now be described.

[0046] It should be noted that the first direction z in the following text is the z-direction shown in the figure, the second direction in the following text is the x-direction shown in the figure, and the third direction in the following text is the y-direction shown in the figure.

[0047] The display panel 100 provided in this application embodiment includes a display module 10 and a refractive module 20 arranged in layers along a first direction z, with the refractive module 20 disposed on the light-emitting side of the display module 10.

[0048] like Figure 1 and Figure 2 As shown, both the display module 10 and the refraction module 20 extend in a plane orthogonal to the first direction z. The display module 10 can be made of rigid material or flexible material. The display module 10 is used to emit parallel light towards the refraction module 20.

[0049] In some embodiments, the display panel 100 is an LCD panel, and the LCD panel includes a display module 10. The display module 10 has a light-emitting layer. In some embodiments, the display module 10 includes an array substrate, a color filter substrate, and a liquid crystal layer. The array substrate includes a first substrate, a gate electrode layer, a first insulating layer, an active layer, a source electrode layer, a drain electrode layer, a second insulating layer, and a pixel electrode layer disposed on the substrate. The color filter substrate includes a second substrate, a filter layer, and a common electrode layer disposed on the second substrate.

[0050] In other embodiments, the display panel 100 is an OLED panel, and the display module 10 includes a base layer, a thin film transistor layer and an insulating layer stacked along a first direction z, and also includes a first electrode layer, a pixel definition layer, an organic light-emitting layer and a second electrode layer.

[0051] The refractive module 20 has at least one internal cavity 001. For example... Figure 2 and Figure 3 As shown, the refractive module 20 has a hollow structure and includes a first cover plate 26 and a second cover plate 27. The first cover plate 26 and the second cover plate 27 are stacked and spaced apart along the first direction z. The second cover plate 27 is located on the side of the first cover plate 26 that is close to the display module 10, so as to form an inner cavity 001 between the first cover plate 26 and the second cover plate 27.

[0052] In some embodiments, the refractive module 20 has an inner cavity 001.

[0053] In other embodiments, the refractive module 20 is provided with a plurality of inner cavities 001, which are arranged along a second direction x, and / or the plurality of inner cavities 001 are arranged along a third direction y.

[0054] At least one lens 21 is provided inside the inner cavity 001, and the lens 21 extends along a second direction x orthogonal to the first direction z.

[0055] Lens 21 is made of transparent material. Lens 21 can be processed on the surface of the first cover plate 26 or the second cover plate 27 facing the inner cavity 001 by any of the following methods: hot remelting, microplastic imprinting, microdroplet jetting, photolithography hot melt molding, grayscale photolithography, micro-nano 3D printing, etc., so that lens 21 is located in the inner cavity 001.

[0056] The inner cavity 001 is used to accommodate at least one of the first fluid 22 and the second fluid 23. The first fluid 22 and the second fluid 23 are immiscible. The refractive index of the first fluid 22 is the same as the refractive index of the first material 211 of the lens 21. The refractive index of the second fluid 23 is greater than the refractive index of the first material 211 of the lens 21 or the refractive index of the second fluid 23 is less than the refractive index of the first material 211 of the lens 21.

[0057] It should be noted that the refractive index of the first fluid 22 is the same as the refractive index of the first material 211 of the lens 21, that is, the refractive index of the first fluid 22 is exactly equal to the refractive index of the first material 211 of the lens 21, or the difference between the refractive index of the first fluid 22 and the refractive index of the first material 211 of the lens 21 is less than or equal to 1% of the refractive index of the first material 211 of the lens 21; the refractive index of the first fluid 22 is different from the refractive index of the first material 211 of the lens 21, that is, the difference between the refractive index of the first fluid 22 and the refractive index of the first material 211 of the lens 21 is greater than 1% of the refractive index of the first material 211 of the lens 21.

[0058] The first fluid 22 and the second fluid 23 fill the inner cavity 001 and the storage cavity 002. In some embodiments, the first fluid 22 and the second fluid 23 are both liquids. In other embodiments, one of the first fluid 22 and the second fluid 23 is a gas and the other of the first fluid 22 and the second fluid 23 is a liquid.

[0059] The refractive index of the first fluid 22 is the same as that of the first material 211 of the lens 21. Therefore, when the first fluid 22 fills the inner cavity 001 and immerses the first material 211 of the lens 21, the parallel light generated by the display module 10 will not be refracted when passing through the interface between the first fluid 22 and the first material 211 of the lens 21.

[0060] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the refractive index of the second fluid 23 is greater than the refractive index of the first material 211 of the lens 21, and the first material 211 of the lens 21 is a convex mirror; in other embodiments (not shown in the figure), the refractive index of the second fluid 23 is less than the refractive index of the first material 211 of the lens 21, and the first material 211 of the lens 21 is a concave mirror.

[0061] Therefore, when the second fluid 23 fills the inner cavity 001 and immerses the first material 211 of the lens 21, the parallel light rays generated by the display module 10 will be refracted when passing through the interface between the second fluid 23 and the first material 211 of the lens 21, such as... Figure 3 As shown, through the interface between lens 21 and the second fluid 23, a portion of the parallel light generated by the display module 10 is refracted to the third side in the y-direction and converged to one of the user's eyes. Through the interface between lens 21 and the second fluid 23, another portion of the parallel light generated by the display module 10 is refracted to the third side in the y-direction and converged to the other eye of the user. By separating the left and right eye images, the brain synthesizes a stereoscopic image with a sense of depth.

[0062] The refractive module 20 is also provided with a liquid storage component 24 and a drive component 25. The liquid storage component 24 has a liquid storage cavity 002, which is connected to the inner cavity 001. The drive component 25 can drive either the first fluid 22 or the second fluid 23 to be contained in the liquid storage component 24, and drive the other of the first fluid 22 and the second fluid 23 to fill the inner cavity 001 and immerse the first material 211 of the lens 21.

[0063] In some embodiments, the liquid storage chamber 002 is in communication with the inner cavity 001 and an opening is provided between the liquid storage chamber 002 and the inner cavity 001.

[0064] In other embodiments, the liquid storage chamber 002 is connected to the inner cavity 001 and a first opening 243 and a second opening 244 are provided between the liquid storage chamber 002 and the inner cavity 001. The first opening 243 allows the first fluid 22 to pass through, and the second opening 244 allows the second fluid 23 to pass through.

[0065] In some embodiments, there is one liquid storage cavity 002, which is connected to multiple inner cavities 001; in other embodiments, there are multiple liquid storage cavities 002, which are connected to multiple inner cavities 001 in a one-to-one correspondence; in other embodiments, there are multiple liquid storage cavities 002, and each liquid storage cavity is connected to two inner cavities 001; in other embodiments, there are multiple liquid storage cavities 002, and each liquid storage cavity is connected to more than two inner cavities 001.

[0066] like Figure 2 , Figure 3 and Figure 4 As shown, the drive assembly 25 can selectively extract either the first fluid 22 or the second fluid 23 from the inner cavity 001 and store it in the reservoir 002, and discharge the other of the first fluid 22 and the second fluid 23 originally in the reservoir 002 into the inner cavity 001, thereby controlling the first material 211 of the lens 21 to be immersed in the first fluid 22 or the first material 211 of the lens 21 to be immersed in the second fluid 23 through the drive assembly 25.

[0067] The beneficial effects of the display panel 100 provided in this application embodiment are as follows: The display panel 100 provided in this application embodiment adjusts the distribution of the first fluid 22 and the second fluid 23 in the inner cavity 001 through the driving component 25. When the first fluid 22 immerses the first material 211 of the lens 21, the interface between the first fluid 22 and the first material 211 of the lens 21 does not refract the light generated by the display module 10, thus realizing 2D display. When the second fluid 23 immerses the first material 211 of the lens 21, the light transmitted through the lens 21 is refracted at the interface between the second fluid 23 and the first material 211 of the lens 21, thereby... Two beams of light, deflected to the sides, enter the user's eyes to achieve 3D display. By adjusting the distribution of the first fluid 22 and the second fluid 23 in the inner cavity 001 through the driving component 25, the switching between 2D display modes can be achieved. Compared with the prior art, which achieves the switching between 2D and 3D display modes by changing the structure of the lens 21 of the display panel 100, the display panel 100 provided in this application can achieve the switching between 2D and 3D display modes by driving the fluid flow, which has the advantage of facilitating the switching between 2D and 3D display modes.

[0068] In some embodiments provided in this application, such as Figure 2 As shown, the display module 10 includes multiple light-emitting units 11. Each light-emitting unit 11 includes at least one pixel unit, which includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel emits red light, the second sub-pixel emits green light, and the third sub-pixel emits blue light. The light-emitting units 11 are arranged in a one-to-one correspondence with the lenses 21 in the first direction z. The orthographic projection of the light-emitting unit 11 in the first direction z lies within the orthographic projection of any lens 21 in the first direction z.

[0069] In some embodiments, the light-emitting unit 11 includes a pixel unit; in other embodiments, the light-emitting unit 11 also includes multiple pixel units.

[0070] In some embodiments provided in this application, the first material 211 of the lens 21 is a convex mirror, and the first material 211 of the lens 21 is convex to the side of the refractive module 20 away from the display module 10. The refractive index of the second fluid 23 is less than the refractive index of the first material 211 of the lens 21.

[0071] like Figure 1 and Figure 5As shown, the first material 211 of the lens 21 includes a first surface 211a and a second surface 211b. The first surface 211a is located on the side of the second surface 211b facing the second cover plate 27. The first surface 211a protrudes towards the second cover plate 27 and is parallel to the display module 10.

[0072] Therefore, the first surface 211a is the interface between the first material 211 of the lens 21 and the first fluid 22 or the second fluid 23. When the second fluid 23 immerses the first material 211 of the lens 21, the parallel light emitted by the display module 10 undergoes a reaction at the first surface 211a as follows: Figure 3 The deflection shown in the figure enables the display panel 100 provided in this embodiment to operate in 3D display mode.

[0073] In some embodiments provided in this application, the lens 21 further includes a second material 212 having a second refractive index. The first material 211 is disposed on the side of the lens 21 away from the display module 10 in the first direction z, and the second material 212 is disposed on the side of the lens 21 facing the display module 10 in the first direction z. The refractive index of the second material 212 is the same as the refractive index of the second fluid 23, and the second material 212 is immersed in the second fluid 23.

[0074] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the second material 212 is a transparent material. The second material 212 is located between the second surface 211b of the first material 211 and the first cover plate 26. The second material 212 is made of a different material than the first material 211. The refractive index of the second material 212 is the same as that of the second fluid 23. The second material 212 is always immersed in the second fluid 23, so that the parallel light generated by the display module 10 does not refract when it passes through the interface between the second material 212 and the second fluid 23.

[0075] Thus, the second material 212 is used to fill a portion of the inner cavity 001 located on the side of the first material 211 facing the first cover plate 26, reducing the volume of the inner cavity 001, thereby enabling the liquid storage assembly 24 to contain the first fluid 22 or the second fluid 23 in the inner cavity 001 into the liquid storage assembly 24.

[0076] In some embodiments provided in this application, the cross-sectional shape of the lens 21 in the second direction x is circular.

[0077] In some embodiments, the cross-sectional shape of the first material 211 and the second material 212 in the second direction x is semi-circular.

[0078] In other embodiments, the cross-sectional shape of the first material 211 in the second direction x is arc-shaped, and the size of the first material 211 in the first direction z is smaller than the size of the second material 212 in the first direction z.

[0079] In some embodiments provided in this application, the liquid storage assembly 24 is provided with a liquid storage chamber 002. The liquid storage chamber 002 is provided with a first opening 243 and a second opening 244 at both ends in the first direction z. The first opening 243 and the second opening 244 are respectively connected to the two ends of the inner cavity 001 in the first direction z. The driving assembly 25 can apply a first force to the first fluid 22 or the second fluid 23 in the liquid storage chamber 002 or the inner cavity 001 to drive the first fluid 22 or the second fluid 23 in the liquid storage chamber 002 or the inner cavity 001 to flow directionally between the liquid storage chamber 002 or the inner cavity 001.

[0080] like Figure 2 , Figure 3 and Figure 4 As shown, there are multiple liquid storage chambers 002, and these multiple liquid storage chambers 002 and multiple inner cavities 001 are arranged alternately along a third direction y, so that the first fluid 22 or the second fluid 23 can flow between the liquid storage chamber 002 and the inner cavity 001 corresponding to the liquid storage chamber 002. Both ends of the liquid storage chamber 002 are connected to the inner cavity 001 in the first direction z, so that either the first fluid 22 or the second fluid 23 in the inner cavity 001 can flow into the liquid storage chamber 002 from either end of the liquid storage chamber 002, and displace the other of the first fluid 22 or the second fluid 23 stored in the liquid storage chamber 002 into the inner cavity 001.

[0081] In some embodiments provided in this application, the drive component 25 is used to provide a first force to the liquid storage chamber 002 and / or the inner cavity 001, the first force being used to drive the first fluid 22 or the second fluid 23 to flow directionally between the liquid storage chamber 002 and the inner cavity 001.

[0082] In some embodiments, the first force is used to drive the first fluid 22 and the second fluid 23 to flow together directionally between the reservoir 002 and the inner cavity 001.

[0083] In other embodiments, a first force is used to selectively drive one of the first fluid 22 and the second fluid 23 to flow directionally between the reservoir 002 and the inner cavity 001, while the other of the first fluid 22 and the second fluid 23 is compressed and forced to flow between the reservoir 002 and the inner cavity 001.

[0084] In some embodiments, the first force may be an electric field force, and the first fluid 22 and / or the second fluid 23 may be a current-carrying body.

[0085] In some embodiments, the first force may be an electric field force, and the first fluid 22 and / or the second fluid 23 may be polar molecular fluids.

[0086] In some embodiments, the first force may be a magnetic force, and the first fluid 22 and / or the second fluid 23 may be a magnetic fluid.

[0087] The driving component 25 of the display panel 100 provided in this application embodiment will be described below with reference to Embodiment 1 and Embodiment 2.

[0088] In Example 1, as Figure 2 and Figure 3 As shown, the driving component 25 includes a first electrode 251 and a second electrode 252. The first electrode 251 is located on the inner wall of the liquid storage cavity 002 away from the display module 10, and the second electrode 252 is located on the inner wall of the liquid storage cavity 002 close to the display module 10. The first electrode 251 and the second electrode 252 are used to generate a directional electric field in the liquid storage cavity 002.

[0089] The first fluid 22 is a liquid with polar molecules, and the second fluid 23 is a liquid with non-polar molecules. The driving component 25 is used to apply a directional electric field to the liquid storage cavity 002. When the polar molecules are in the external electric field, not only will their electric dipole moments be subjected to torque and oriented, but when the electric field strength is not uniform, the electric field forces on the two ends of the polar molecules are different. In the electric field, the polar molecules will also undergo net migration towards the position with higher electric field strength due to the electric field gradient.

[0090] Therefore, when the driving component 25 applies a directional electric field to the liquid storage cavity 002, the electric field strength in the liquid storage cavity 002 is greater than the electric field strength in the inner cavity 001. Under the action of the electric field force, the first fluid 22 is driven to move into the liquid storage cavity 002, and a portion of the second fluid 23 in the liquid storage cavity 002 is squeezed into the inner cavity 001, so that both the first material 211 and the second material 212 are immersed in the second fluid 23, and the display panel 100 provided in this embodiment of the application is in 2D display mode.

[0091] In some embodiments provided in this application, an insulating layer is provided on the surface of the first electrode 251 facing the liquid storage cavity 002 and the surface of the second electrode 252 facing the liquid storage cavity 002.

[0092] In Example 2, as Figure 4 As shown, the driving component 25 includes a first electrode 251 and a second electrode 252. The first electrode 251 is located on the inner wall of the inner cavity 001 away from the display module 10, and the second electrode 252 is located on the inner wall of the inner cavity 001 close to the display module 10. The first electrode 251 and the second electrode 252 are used to generate a directional electric field in the inner cavity 001.

[0093] The first fluid 22 is a non-polar liquid, the second fluid 23 is a polar liquid, and the driving component 25 is used to apply a directional electric field to the inner cavity 001.

[0094] Therefore, when the driving component 25 applies a directional electric field to the inner cavity 001, the electric field strength in the inner cavity 001 is greater than the electric field strength in the liquid storage cavity 002. Under the action of the electric field force, the second fluid 23 is driven to move into the inner cavity 001, displacing part of the first fluid 22 in the inner cavity 001 into the inner cavity 001, so that both the first material 211 and the second material 212 are immersed in the second fluid 23, so that the display panel 100 provided in this application embodiment is in 2D display mode.

[0095] In some embodiments provided in this application, the surface of the first electrode 251 facing the inner cavity 001 and the surface of the second electrode 252 facing the inner cavity 001 are both provided with an insulating layer.

[0096] In the above embodiment 2, the first fluid 22 is silicone oil, the first material 211 is epoxy resin, and the refractive index of both the first fluid 22 and the first material 211 is 1.58; the second fluid 23 is glycerol, the second material 212 is borosilicate glass, and the refractive index of both the second fluid 23 and the second material 212 is 1.47.

[0097] In some embodiments, the density of the first fluid 22 is the same as the density of the second fluid 23.

[0098] In some embodiments provided in this application, such as Figure 2 and Figure 4 As shown, when the drive assembly 25 does not apply a directional electric field in the liquid storage cavity 002, the first fluid 22 and the second fluid 23 are layered in the inner cavity 001, wherein the first fluid 22 is away from the display module 10 so that the first material 211 is immersed in the first fluid 22, and the second fluid 23 is close to the display module 10 so that the second material 212 is immersed in the second fluid 23.

[0099] In some embodiments provided in this application, the contact angle between the inner wall surface of the inner cavity 001 on the side away from the display module 10 and the first fluid 22 is less than 90°, and the contact angle between the inner wall surface of the inner cavity 001 on the side close to the display module 10 and the second fluid 23 is less than 90°.

[0100] Therefore, the inner wall surface of the inner cavity 001 away from the display module 10 is attracted to the first fluid 22, and the inner wall surface of the inner cavity 001 close to the display module 10 is attracted to the second fluid 23. When the electric field intensity between the first cover plate 26 and the second cover plate 27 is uniformly distributed, under the action of surface tension, the first fluid 22 is distributed close to the first cover plate 26, so that the first fluid 22 immerses the first material 211, and the second fluid 23 is distributed close to the second cover plate 27, so that the second fluid 23 immerses the second material 212.

[0101] In some embodiments provided in this application, the contact angle between the inner wall surface of the inner cavity 001 on the side closer to the display module 10 and the first fluid 22 is greater than 90°, and the contact angle between the inner wall surface of the inner cavity 001 on the side farther from the display module 10 and the second fluid 23 is greater than 90°.

[0102] Therefore, the inner wall surface of the inner cavity 001 near the display module 10 is permeable to the first fluid 22, and the inner wall surface of the inner cavity 001 away from the display module 10 is permeable to the second fluid 23. When the electric field intensity between the first cover plate 26 and the second cover plate 27 is uniformly distributed, under the action of surface tension, the first fluid 22 is distributed close to the first cover plate 26, so that the first fluid 22 immerses the first material 211. Part of the first fluid 22 and part of the second fluid 23 are distributed in the liquid storage cavity 002. The second fluid 23 is distributed close to the second cover plate 27 and immerses the second material 212.

[0103] In some embodiments, the inner wall surface of the inner cavity 001 on the side away from the display module 10 is attracted to the first fluid 22 and desensitized to the second fluid 23.

[0104] In some other embodiments, the inner wall surface of the cavity 001 near the display module 10 is attracted to the second fluid 23 and desensitized to the first fluid 22.

[0105] In some other embodiments, the inner wall surface of the inner cavity 001 on the side away from the display module 10 is attracted to the first fluid 22 and de-attracted from the second fluid 23, while the inner wall surface of the inner cavity 001 on the side close to the display module 10 is attracted to the second fluid 23 and de-attracted from the first fluid 22.

[0106] In some embodiments, the first cover plate 26 is a transparent insulating material containing polar molecules; in other embodiments, the surface of the first cover plate 26 facing the inner cavity 001 is provided with a first coating, which is a transparent insulating material containing polar molecules.

[0107] In some embodiments, the second cover plate 27 is a transparent insulating material containing non-polar molecules; in other embodiments, the surface of the second cover plate 27 facing the inner cavity 001 is provided with a second coating, which is a transparent insulating material containing non-polar molecules.

[0108] Therefore, the contact angle between the first cover plate 26 and the first fluid 22 is less than 90°, and the contact angle between the first cover plate 26 and the first fluid 22 is greater than 90°. Also, the contact angle between the surface of the second cover plate 27 and the second fluid 23 is less than 90°, and the contact angle between the surface of the second cover plate 27 and the first fluid 22 is greater than 90°.

[0109] In some embodiments, the first electrode 251 is a transparent conductive material containing polar molecules, and the second electrode 252 is a transparent conductive material containing non-polar molecules.

[0110] Therefore, the contact angle between the first electrode 251 and the first fluid 22 is less than 90°, the contact angle between the first electrode 251 and the second fluid 23 is greater than 90°, and the contact angle between the surface of the second electrode 252 and the second fluid 23 is less than 90°, while the contact angle between the surface of the second electrode 252 and the first fluid 22 is greater than 90°.

[0111] In some embodiments, a first partition 241 and a second partition 242 are alternately arranged in a direction orthogonal to the first direction x between the first cover plate 26 and the second cover plate 27. An inner cavity 001 is formed between the first partition 241 and an adjacent second partition 242, and a liquid storage cavity 002 is formed between the first partition 241 and another adjacent second partition 242.

[0112] In some embodiments, the first partition 241 and the second partition 242 are made of transparent material.

[0113] In other embodiments, the first partition 241 and the second partition 242 are made of light-shielding material.

[0114] In some embodiments provided in this application, one end of the liquid storage cavity 002 is connected to its inner cavity 001 on the third-direction y-side, and the other end of the liquid storage cavity 002 is connected to its inner cavity 001 on the other side of the third-direction y-side.

[0115] like Figure 2 , Figure 3 and Figure 4 As shown, the first partition 241 is arranged at a distance between the end of the first partition 241 near the display module 10 and the second cover plate 27 in the first direction z to form a first opening 243. The end of the first partition 241 away from the display module 10 in the first direction z is connected to the first cover plate 26. The end of the second partition 242 away from the display module 10 in the first direction z is arranged at a distance between the second partition 242 and the first cover plate 26 to form a second opening 244. The end of the second partition 242 near the display module 10 in the first direction z is connected to the second cover plate 27.

[0116] For a single liquid storage chamber 002, the first opening 243 connects the liquid storage chamber 002 to the inner cavity 001 on one side, and the second opening 244 connects the liquid storage chamber 002 to the inner cavity 001 on the other side.

[0117] Therefore, when processing the refractive module 20, multiple first partitions 241 are processed on the first cover plate 26, multiple second partitions 242 are processed on the second cover plate 27, and then the first cover plate 26 and the second cover plate 27 are joined together to complete the processing of the liquid storage cavity 002, making the structure of the refractive module 20 easier to process.

[0118] In some embodiments provided in this application, the refractive module 20 is provided with a plurality of inner cavities 001 and a plurality of liquid storage components 24. In some embodiments, the inner cavities 001 and the liquid storage components 24 are arranged alternately along a third direction y; in other embodiments, the inner cavities 001 and the liquid storage components 24 are arranged alternately along a second direction x.

[0119] Each cavity 001 contains a lens 21.

[0120] like Figure 2 , Figure 3 and Figure 4 As shown, the inner cavity 001, the liquid storage cavity 002 and the driving component 25 are distributed in a one-to-one correspondence, so that by independently controlling the driving component 25, the parallel light generated by the display module 10 can have different states after passing through different lens 21 surfaces.

[0121] In some states (not shown in the figure), some of the parallel light rays generated by the display module 10 are refracted to both sides in the third direction y after passing through the refraction module 20, and some of the parallel light rays generated by the display module 10 remain parallel light rays after passing through the refraction module 20, so that the display panel 100 provided in this application embodiment can work in both 2D display mode and 3D display mode at the same time.

[0122] In other states, such as Figure 3 As shown, the parallel light generated by the display module 10 is refracted to both sides in the third direction y after passing through the refraction module 20, so that the display panel 100 provided in this embodiment of the application can work in 3D display mode.

[0123] In other states, such as Figure 2 and Figure 4 As shown, the parallel light generated by the display module 10 remains parallel after passing through the refraction module 20, enabling the display panel 100 provided in this embodiment to operate in 2D display mode.

[0124] Therefore, the display panel 100 provided in this application embodiment can operate in 2D display mode, 3D display mode and 2D / 3D mixed display mode by independently or as a whole controlling multiple driving components 25, which reduces the difficulty of control on the one hand and reduces energy consumption on the other.

[0125] In some embodiments, a plurality of lenses 21 are arranged along a third direction y, with a portion of the lenses 21 immersed in a first fluid 22 and another portion of the lenses immersed in a second fluid 23, so that the display panel 100 provided in the embodiments of this application can realize 2D / 3D partitioned display in the third direction y.

[0126] In some embodiments, a plurality of lenses 21 are arranged along a third direction y, and a plurality of lenses are arranged along a second direction x, so that the display panel 100 provided in this application embodiment can realize 2D / 3D partitioned display in both the second direction x and the third direction y.

[0127] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
