[0034] In some embodiments, the display panel 100 is an LCD panel, and the LCD panel comprises the display module 10, and the display module 10 is provided with a light-emitting layer.

The display module 10 further comprises a first electrode layer, a pixel definition layer, an organic light-emitting layer and a second electrode layer.

[0036] The refraction module 20 is provided with at least one inner cavity 001. As shown in Figure 2 and Figure 3 The refraction module 20 is a hollow structure, and the refraction module 20 comprises a first cover plate 26 and a second cover plate 27. The first cover plate 26 and the second cover plate 27 are arranged in a stack along the first direction z and are spaced apart. The second cover plate 27 is located on a side of the first cover plate 26 close to the display module 10, so as to form the inner cavity 001 between the first cover plate 26 and the second cover plate 27.

[0037] In some embodiments, the refraction module 20 is provided with one inner cavity 001.

[0038] In other embodiments, the refraction module 20 is provided with a plurality of inner cavities 001. The plurality of inner cavities 001 are arranged along a second direction x, and / or the plurality of inner cavities 001 are arranged along a third direction y.

[0039] The inner cavity 001 is provided with at least one lens 21, and the lens 21 extends along the second direction x which is orthogonal to the first direction z.

[0040] The lens 21 is made of transparent material. The lens 21 can be processed on a surface of the first cover plate 26 or the second cover plate 27 facing the inner cavity 001 by any one of the following methods: hot reflow, micro-plastic stamping, micro-droplet jetting, photolithography hot melting forming, gray-scale photolithography and micro-nano 3D printing.

[0041] The inner cavity 001 is used to contain at least one of a first fluid 22 and a second fluid 23. The first fluid 22 and the second fluid 23 are mutually insoluble. The refractive index of the first fluid 22 is the same as the refractive index of a 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.

[0042] 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, i.e. the refractive index of the first fluid 22 is completely 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; or the refractive index of the first fluid 22 is different from the refractive index of the first material 211 of the lens 21, i.e. 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.

[0043] The first fluid 22 and the second fluid 23 are filled in the inner cavity 001 and the liquid storage cavity 002. In some embodiments, both the first fluid 22 and the second fluid 23 are liquids, and 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.

[0044] The refractive index of the first fluid 22 is the same as the refractive index of the first material 211 of the lens 21, so that 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.

[0045] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 4 , 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.

[0046] Therefore, when the second fluid 23 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 be refracted when passing through the interface between the second fluid 23 and the first material 211 of the lens 21, as shown in Figure 3 , a part of the parallel light generated by the display module 10 is refracted and converged to one eye of the user through the interface between the lens 21 and the second fluid 23 to one side in the third direction y, and another part of the parallel light generated by the display module 10 is refracted and converged to the other eye of the user through the interface between the lens 21 and the second fluid 23 to the other side in the third direction y, so that the left and right eye image separation makes the brain synthesize a stereoscopic image with depth perception.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] The display panel 100 provided in the embodiments of the present application has the beneficial effects that: the display panel 100 provided in the embodiments of the present application adjusts the distribution of the first fluid 22 and the second fluid 23 in the inner cavity 001 through the driving assembly 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, thereby realizing 2D display, when the second fluid 23 immerses the first material 211 of the lens 21, the light passing through the lens 21 is refracted at the interface between the second fluid 23 and the first material 211 of the lens 21, thereby deflecting to both sides, and the two deflected light rays respectively enter the eyes of the user, thereby realizing 3D display, and the display panel 100 provided in the embodiments of the present application can realize switching between the 2D display mode and the 2D display mode by adjusting the distribution of the first fluid 22 and the second fluid 23 in the inner cavity 001, compared with the prior art which realizes switching between the 2D display mode and the 3D display mode by changing the structure of the lens 21 of the display panel 100, the display panel 100 provided in the embodiments of the present application can realize switching between the 2D display mode and the 3D display mode by driving the fluid flow, thereby having the advantage of facilitating switching between the 2D display mode and the 3D display mode.

[0053] In some embodiments provided in the present application, as shown in Figure 2 The display module 10 includes a plurality of light emitting units 11, the light emitting unit 11 includes at least one pixel unit, the pixel unit includes a first sub-pixel, a second sub-pixel and a third sub-pixel, the first sub-pixel is used for emitting red light, the second sub-pixel is used for emitting green light, and the third sub-pixel is used for emitting blue light. The light emitting unit 11 and the lens 21 are arranged one by one in the first direction z, and the orthographic projection of the light emitting unit 11 in the first direction z is located in the orthographic projection of any one lens 21 in the first direction z.

[0054] In some embodiments, the light emitting unit 11 includes one pixel unit; in other embodiments, the light emitting unit 11 further includes a plurality of pixel units.

[0055] In some embodiments provided in the present application, the first material 211 of the lens 21 is a convex mirror, the first material 211 of the lens 21 is convex to the side of the refracting module 20 away from the display module 10, and the refractive index of the second fluid 23 is less than the refractive index of the first material 211 of the lens 21.

[0056] As shown in Figure 1 and Figure 5 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 is convex to the second cover plate 27, and the first surface 211a is parallel to the display module 10.

[0057] Thus, 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 is deflected at the first surface 211a as shown in the following formula, so that the display panel 100 provided in the embodiments of the present application works in the 3D display mode.

The refractive index of the second material 212 is the same as that of the second fluid 23, and the second material 212 is immersed in the second fluid 23.

[0059] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , the second material 212 is transparent, the second material 212 is located between the second surface 211b of the first material 211 and the first cover plate 26, the material of the second material 212 is different from that of the first material 211, the refractive index of the second material 212 is the same as that of the second fluid 23, and 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 passing through the interface between the second material 212 and the second fluid 23.

[0060] Thus, the second material 212 is used to fill the inner cavity 001 on the side of the first material 211 facing the first cover plate 26, so as to reduce the volume of the inner cavity 001, thereby enabling the liquid storage assembly 24 to accommodate the first fluid 22 or the second fluid 23 in the inner cavity 001 into the liquid storage assembly 24.

[0065] As shown in Figure 2 , Figure 3 and Figure 4 , the liquid storage cavity 002 has a plurality of liquid storage cavities 002, and the plurality of liquid storage cavities 002 and the plurality of inner cavities 001 are arranged alternately along the third direction y, so that the first fluid 22 or the second fluid 23 can flow between the liquid storage cavity 002 and the inner cavity 001 corresponding to the liquid storage cavity 002. The two ends of the liquid storage cavity 002 in the first direction z are in communication with the inner cavity 001, so that any one of the first fluid 22 or the second fluid 23 in the inner cavity 001 can flow into the liquid storage cavity 002 from any one end of the liquid storage cavity 002, and the other one of the first fluid 22 or the second fluid 23 stored in the liquid storage cavity 002 is expelled into the inner cavity 001.

[0066] In some embodiments provided in the present application, the driving assembly 25 is used to provide the liquid storage cavity 002 and / or the inner cavity 001 with a first force, and the first force is used to drive the first fluid 22 or the second fluid 23 to flow directionally between the liquid storage cavity 002 and the inner cavity 001.

[0068] In another embodiment, the first force is used to selectively drive one of the first fluid 22 and the second fluid 23 to flow directionally between the liquid storage cavity 002 and the inner cavity 001, and the other one of the first fluid 22 and the second fluid 23 is extruded to flow between the liquid storage cavity 002 and the inner cavity 001.

[0069] In some embodiments, the first force can be an electric field force, and the first fluid 22 and / or the second fluid 23 can be a charged fluid.

[0070] In some embodiments, the first force can be an electric field force, and the first fluid 22 and / or the second fluid 23 can be a polar molecular fluid.

[0071] In some embodiments, the first force can be a magnetic field force, and the first fluid 22 and / or the second fluid 23 can be a magnetic fluid. In some embodiments, the first force can be a magnetic field force, and the first fluid 22 and / or the second fluid 23 can be a magnetic fluid.

[0072] The driving assembly 25 of the display panel 100 provided in the embodiments will be described below in combination with Embodiment One and Embodiment Two.

[0073] In Embodiment One, as shown in Figure 2 and Figure 3 , the driving assembly 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, and the first electrode 251 and the second electrode 252 are used to generate a directional electric field in the liquid storage cavity 002.

[0074] The first fluid 22 is a liquid of polar molecules, and the second fluid 23 is a liquid of non-polar molecules, and the driving assembly 25 is used to apply a directional electric field to the liquid storage cavity 002. When the polar molecules are in an external electric field, not only the electric dipole moment of the polar molecules will be subjected to a moment of force to be oriented, but also the polar molecules will produce net migration due to the electric field gradient to the position with higher electric field intensity when the electric field intensity is uneven.

[0075] Therefore, when the driving assembly 25 applies a directional electric field to the liquid storage cavity 002, the electric field intensity in the liquid storage cavity 002 is greater than that in the inner cavity 001, and the first fluid 22 is driven to move to the liquid storage cavity 002 under the action of the electric field force, expelling part of the second fluid 23 in the liquid storage cavity 002 to the inner cavity 001, so that the first material 211 and the second material 212 are both immersed in the second fluid 23, and the display panel 100 provided in the embodiments is in a 2D display mode.

[0076] In some embodiments provided in the present application, 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 are both provided with an insulating layer.

[0077] In Embodiment Two, as shown in Figure 4 , the driving assembly 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, and the first electrode 251 and the second electrode 252 are used to generate a directional electric field in the inner cavity 001.

[0078] The first fluid 22 is a liquid of non-polar molecules, and the second fluid 23 is a liquid of polar molecules, and the driving assembly 25 is used to apply a directional electric field to the inner cavity 001.

[0079] Thus, when the driving assembly 25 applies a directional electric field into the inner cavity 001, the electric field intensity in the inner cavity 001 is greater than that in the liquid storage cavity 002, and the second fluid 23 is driven to move into the inner cavity 001 under the electric field force, so as to expel part of the first fluid 22 in the inner cavity 001 into the inner cavity 001, thereby making the first material 211 and the second material 212 both immerse in the second fluid 23, and making the display panel 100 provided in the embodiments of the present application be in the 2D display mode.

[0080] In some embodiments two provided in the present 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.

[0081] In the above-mentioned embodiments two, the first fluid 22 is silicone oil, the material of the first material 211 is epoxy resin, and the refractive indexes of the first fluid 22 and the first material 211 are both 1.58; the second fluid 23 is glycerol, the second material 212 is borosilicate glass, and the refractive indexes of the second fluid 23 and the second material 212 are both 1.47.

[0082] In some embodiments, the density of the first fluid 22 is the same as that of the second fluid 23.

[0083] In some embodiments provided in the present application, as shown in Figure 2 and Figure 4 shown, in the case that the driving assembly 25 does not apply a directional electric field into 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 as to immerse the first material 211 in the first fluid 22, and the second fluid 23 is close to the display module 10 so as to immerse the second material 212 in the second fluid 23.

[0084] In some embodiments provided in the present application, the contact angle between the inner wall surface of the inner cavity 001 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 close to the display module 10 and the second fluid 23 is less than 90°.

[0085] Thus, the inner wall surface of the inner cavity 001 away from the display module 10 is hydrophilic to the first fluid 22, and the inner wall surface of the inner cavity 001 close to the display module 10 is hydrophilic 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, the first fluid 22 is distributed close to the first cover plate 26 under the surface tension, so as to immerse the first fluid 22 in the first material 211, and the second fluid 23 is distributed close to the second cover plate 27, so as to immerse the second fluid 23 in the second material 212.

[0086] In some embodiments, the inner wall surface of the inner cavity 001 close to the display module 10 has a contact angle greater than 90° with the first fluid 22, and the inner wall surface of the inner cavity 001 away from the display module 10 has a contact angle greater than 90° with the second fluid 23.

[0087] Thus, the inner wall surface of the inner cavity 001 close to the display module 10 is hydrophobic to the first fluid 22, and the inner wall surface of the inner cavity 001 away from the display module 10 is hydrophobic 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, the first fluid 22 is distributed close to the first cover plate 26 under the action of surface tension, 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, and the second fluid 23 is distributed close to the second cover plate 27, and the second fluid 23 immerses the second material 212.

[0088] In some embodiments, the inner wall surface of the inner cavity 001 away from the display module 10 is hydrophilic to the first fluid 22 and hydrophobic to the second fluid 23.

[0089] In some other embodiments, the inner wall surface of the inner cavity 001 close to the display module 10 is hydrophilic to the second fluid 23 and hydrophobic to the first fluid 22.

[0090] In some other embodiments, the inner wall surface of the inner cavity 001 away from the display module 10 is hydrophilic to the first fluid 22 and hydrophobic to the second fluid 23, and the inner wall surface of the inner cavity 001 close to the display module 10 is hydrophilic to the second fluid 23 and hydrophobic to the first fluid 22.

[0091] In some embodiments, the first cover plate 26 is a transparent insulating material including polar molecules; in some other embodiments, the surface of the first cover plate 26 close to the inner cavity 001 is provided with a first coating layer, and the first coating layer is a transparent insulating material including polar molecules.

[0092] In some embodiments, the second cover plate 27 is a transparent insulating material including non-polar molecules; in some other embodiments, the surface of the second cover plate 27 close to the inner cavity 001 is provided with a second coating layer, and the second coating layer is a transparent insulating material including non-polar molecules.

[0093] Thus, the contact angle between the first cover plate 26 and the first fluid 22 is less than 90°, the contact angle between the first cover plate 26 and the first fluid 22 is greater than 90°, and 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°.

[0094] In some embodiments, the first electrode 251 is a transparent conductive material including polar molecules, and the second electrode 252 is a transparent conductive material including non-polar molecules.

[0095] 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°.

[0096] 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.

[0097] In some embodiments, the first partition 241 and the second partition 242 are made of transparent material.

[0098] In other embodiments, the first partition 241 and the second partition 242 are made of light-shielding material.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] Each cavity 001 contains a lens 21.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] In some embodiments, the plurality of lenses 21 are arranged along the third direction y, and the plurality of lenses are arranged along the second direction x, so that the display panel 100 provided by the embodiments of the present application can realize 2D / 3D partition display in the second direction x and the third direction y.

[0112] The above only represents the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
