[0039] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0040] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] 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.

[0044] However, the display panel in the related technology can only switch completely between 2D display mode and 3D display mode, and cannot be in 2D display mode in one area and 3D display mode in another area at the same time.

[0045] To address the aforementioned technical problems, embodiments of this application provide a refractive module, a display panel using the refractive module, 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 (Micro LED / μLED) display panel, a light-emitting diode (LED) panel, or a liquid crystal display (LCD) 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.

[0046] The display panel provided in this application embodiment has a refractive module on the light-emitting side of the display module. The refractive module has an inner cavity, and the inner cavity has a filler and multiple rotating bodies. The multiple rotating bodies can rotate between a first position and a second position, respectively, so that the display panel can switch between 3D display mode and 2D display mode. When all the multiple rotating bodies are in the first position, a complete 3D display is achieved. When all the multiple rotating bodies are in the second position, a complete 2D display is achieved. When some of the multiple rotating bodies are in the first position and another part of the multiple rotating bodies are in the second position, a partial 2D display and a partial 3D display can be achieved. Compared with the display panels in related technologies, which can only change the display mode as a whole, the display device provided in this application embodiment has the advantage of being able to simultaneously achieve a partial 2D display and a partial 3D display.

[0047] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The display panel 100 provided in the embodiments of this application will now be described.

[0048] The display panel 100 provided in this application embodiment includes a display module 10 and a refractive module 20 stacked along a first direction z.

[0049] 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.

[0050] 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, an insulating layer one, an active layer, a source electrode layer, a drain electrode layer, an insulating layer two, and a pixel electrode layer. The color filter substrate includes a second substrate, a filter layer, and a common electrode layer.

[0051] 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.

[0052] The display module 10 is provided with multiple light-emitting units 11, and the refractive module 20 is located on the light-emitting side of the display module 10.

[0053] In some embodiments, such as Figure 2As shown, the light-emitting unit 11 includes multiple pixel units, each pixel unit including a first sub-pixel, a second sub-pixel and a third sub-pixel. The first sub-pixel is used to emit red light, the second sub-pixel is used to emit green light and the third sub-pixel is used to emit blue light.

[0054] In some embodiments, the light-emitting unit 11 includes a single pixel unit; in other embodiments, the light-emitting unit 11 may also include multiple pixel units.

[0055] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The refractive module 20 provided in the embodiments of this application will now be described.

[0056] It should be noted that the first direction 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.

[0057] like Figure 2 and Figure 3 As shown, the refractive module 20 has a hollow structure and includes a first cover plate 24a and a second cover plate 24b. The first cover plate 24a and the second cover plate 24b are stacked and spaced apart along the first direction z. The second cover plate 24b is located on the side of the first cover plate 24a that is close to the display module 10, so as to form an inner cavity 001 between the first cover plate 24a and the second cover plate 24b.

[0058] In some embodiments, the refractive module 20 is provided with a plurality of inner cavities 001, which are arranged along a second direction x and / or along a third direction y. Each inner cavity 001 is provided with one or more rotating bodies 21, and each inner cavity 001 can be regarded as an independent and controllable optical channel for adjusting the light from the display module 10.

[0059] In other embodiments, the refractive module 20 has an inner cavity 001, in which a plurality of rotating bodies 21 are provided.

[0060] The rotating body 21 is rotatably disposed in the inner cavity 001. The axis of rotation of the rotating body 21 extends along a second direction x orthogonal to the first direction z. The rotating body 21 includes a first lens portion 211 and a second lens portion 212. The first lens portion 211 and the second lens portion 212 are arranged radially along the rotating body 21. The refractive index of the first lens portion 211 is different from that of the second lens portion 212. The refractive index of the second lens portion 212 is the same as that of the filling body 22.

[0061] It should be noted that the refractive index of the first lens portion 211 is different from that of the second lens portion 212, that is, the difference between the refractive index of the first lens portion 211 and the refractive index of the second lens portion 212 is greater than 5% of the refractive index of the first lens portion 211 or the refractive index of the second lens portion 212; the refractive index of the second lens portion 212 is the same as that of the filler 22, that is, the difference between the refractive index of the second lens portion 212 and the refractive index of the filler 22 is less than or equal to 5% of the refractive index of the second lens portion 212 or the refractive index of the filler 22.

[0062] The refractive index of the first lens portion 211 is greater than the refractive index of the second lens portion 212, or the refractive index of the first lens portion 211 is less than the refractive index of the second lens portion 212.

[0063] In some embodiments, such as Figure 2 and Figure 3 As shown, a rotating body 21 is provided in the inner cavity 001.

[0064] In some other embodiments (not shown in the figure), the inner cavity 001 is provided with a plurality of rotating bodies 21, and the plurality of rotating bodies 21 in the inner cavity 001 are arranged along the third direction y.

[0065] In some other embodiments (not shown in the figures), a portion of the inner cavity 001 has a rotating body 21, while another portion of the inner cavity 001 has multiple rotating bodies 21.

[0066] In some embodiments, such as Figure 2 and Figure 3 As shown, the first lens portion 211 is a convex lens portion, and the refractive index of the first lens portion 211 is greater than the refractive index of the filler 22 and the refractive index of the second lens portion 212.

[0067] In other embodiments, such as Figure 4 As shown, the first lens portion 211 is a concave lens portion, and the refractive index of the first lens portion 211 is less than the refractive index of the filler 22 and the refractive index of the second lens portion 212.

[0068] like Figure 2 As shown, in the first position, the first lens portion 211 is correspondingly disposed on the light-emitting side of the light-emitting unit 11 in the first direction z, that is, the first lens portion 211 is located on the propagation path of the light generated by the light-emitting unit 11. The orthographic projection of the light-emitting unit 11 in the first direction z is located within the outline of the orthographic projection of the first lens portion 211 in the first direction z. When the parallel light rays generated by the light-emitting unit 11 along the first direction z pass through the first lens portion 211, they are refracted on both sides of the first lens portion 211 in the third direction y on the surface of the first lens portion 211, so that a part of the parallel light rays generated by a part of the pixel unit is refracted to the user's left eye, and another part of the parallel light rays generated by another part of the pixel unit is refracted to the user's right eye, thereby realizing 3D display.

[0069] like Figure 3 As shown, in the second position, the orthographic projection of the light-emitting unit 11 in the first direction z and the orthographic projection of the first lens portion 211 in the first direction z are misaligned. That is, the first lens portion 211 is not in the direct propagation path of the light emitted by the light-emitting unit 11. The parallel light generated by the light-emitting unit 11 along the first direction z will not pass directly through the first lens portion 211, but will pass through the second lens portion 212 and the filler 22 along the first direction z. Since the refractive index of the second lens portion 212 is the same as that of the filler 22, the overall effect of the second lens portion 212 and the filler 22 on the light is close to that of a uniform and unbiased medium. When the light generated by the light-emitting unit 11 passes through the boundary between the second lens portion 212 and the filler 22, the boundary between the second lens portion 212 and the filler 22 will not refract the parallel light, thereby realizing 2D display.

[0070] In some embodiments, such as Figure 2 and Figure 3 As shown, the filling body 22 is a liquid, the rotating body 21 is a solid, and the second lens part 212 is immersed in the filling body 22, so that the second lens part 212 can rotate in the inner cavity 001.

[0071] In some of the above embodiments, the density of the rotating body 21 is the same as the density of the filling body 22, and the density of the first lens portion 211 is the same as the density of the rotating body 21.

[0072] In some of the above embodiments, the first lens portion 211 is made of epoxy resin (refractive index 1.58), the rotating body 21 is made of borosilicate glass (refractive index 1.47), and the filler 22 is made of glycerol (refractive index 1.47).

[0073] In some other embodiments (not shown in the figures), the filler 22 is a solid, the rotating body 21 is a solid, the filler 22 has a circular hole extending along the second direction x, and the rotating body 21 is rotatably assembled in the circular hole.

[0074] In some embodiments (not shown in the figure), the filler 22 is a solid, the rotating body 21 is a liquid, the filler 22 has a circular hole extending along the second direction x, and the rotating body 21 fills the circular hole.

[0075] The refraction module 20 includes multiple drive components 23, which are used to drive the rotating body 21 to rotate between a first position and a second position respectively.

[0076] In some embodiments, the refraction module 20 includes multiple cavities 001. The driving component 23 can drive the rotating bodies 21 in different cavities 001 respectively, so that the different rotating bodies 21 are located in different positions. This allows the light generated by a portion of the light-emitting units 11 to be refracted by the first lens portion 211 to both sides in the third direction y when passing through the refraction module 20, thus achieving 3D display. The light generated by another portion of the light-emitting units 11 remains parallel light after passing through the refraction module 20, thus achieving 2D display.

[0077] In other embodiments, the refractive module 20 includes a single inner cavity 001, and the driving component 23 is capable of driving a plurality of rotating bodies 21 in the inner cavity 001 respectively, so that the plurality of rotating bodies 21 in the inner cavity 001 are located at different positions.

[0078] In some embodiments, the display panel 100 includes a first region and a second region. The driving component 23 can adjust a plurality of rotating bodies 21 in the first region to a first position and adjust a plurality of rotating bodies 21 in the second region to a second position, so that the first region operates in 3D display mode and the second region operates in 2D display mode.

[0079] In some embodiments, the drive component 23 can drive each rotating body 21 to rotate individually.

[0080] In other embodiments, the drive component 23 can simultaneously drive multiple rotating bodies 21 in the inner cavity 001 to rotate, that is, the multiple rotating bodies 21 in the inner cavity 001 are in the same position.

[0081] The display panel 100 provided in this application embodiment drives the first lens section 211 to move between a first position and a second position via the driving component 23. In the first position, the parallel light rays generated by the light-emitting unit 11 pass through the first lens section 211 and are refracted. A portion of the refracted light rays is deflected toward the user's left eye, and another portion of the refracted light rays is deflected toward the user's right eye. 3D display is achieved by the difference between the images of the user's two eyes. In the second position, the first lens section 211 avoids the parallel light rays generated by the light-emitting unit 11, so that the parallel light rays generated by the light-emitting unit 11 do not undergo refraction or deflection during the process of passing through the refraction module 20, thereby achieving 2D display.

[0082] The beneficial effects of the refraction module 20 provided in this application embodiment are as follows: Compared with the prior art display panel, which can only switch completely between 2D display mode and 3D display mode, the refraction module 20 provided in this application embodiment enables the display panel 100 to achieve complete 3D display when all the rotating bodies 21 are in the first position, enables the display panel 100 to achieve complete 2D display when all the rotating bodies 21 are in the second position, and enables the display panel 100 to achieve partial 2D display and partial 3D display when some of the rotating bodies 21 are in the first position and some of the rotating bodies 21 are in the second position. Thus, the refraction module provided in this application embodiment enables the display panel 100 to simultaneously achieve partial 2D display and partial 3D display.

[0083] In some embodiments provided in this application, the refraction module 20 includes a drive component 23 for driving the rotating body 21 to rotate between a first position and a second position.

[0084] In some embodiments, the drive component 23 can drive each rotating body 21 to rotate individually.

[0085] In other embodiments, the drive component 23 can simultaneously drive multiple rotating bodies 21 in the inner cavity 001 to rotate, that is, the multiple rotating bodies 21 in the inner cavity 001 are in the same position.

[0086] Thus, by driving component 23, some of the light generated by light-emitting unit 11 is refracted by first lens 211 to both sides in the third direction y when passing through refraction module 20, achieving 3D display, while the light generated by other light-emitting unit 11 remains parallel light after passing through refraction module 20, achieving 2D display.

[0087] In addition, the drive assembly 23 can drive all rotating bodies 21 in the refraction module 20 to be in the first position or the second position.

[0088] In some embodiments, the display panel 100 includes a first region and a second region. The driving component 23 can adjust a plurality of rotating bodies 21 in the first region to a first position and adjust a plurality of rotating bodies 21 in the second region to a second position, so that the first region operates in 3D display mode and the second region operates in 2D display mode.

[0089] In some embodiments, such as Figure 5 As shown, the rotating body 21 is a cylindrical structure extending along the second direction x. The first lens part 211 and the second lens part 212 are both made of materials with a light transmittance greater than or equal to 80%. The orthographic projection of the first lens part 211 and the second lens part 212 in the second direction x is a complementary arc shape, or the orthographic projection of the first lens part 211 and the second lens part 212 in the second direction x is a semicircle.

[0090] In some embodiments provided in this application, the dimension of the first lens portion 211 in the radial direction of the rotating body 21 is smaller than the dimension of the second lens portion 212 in the radial direction of the rotating body 21.

[0091] Therefore, the first lens portion 211 has a width dimension orthogonal to its optical axis and a thickness dimension along its optical axis direction. The width dimension of the first lens portion 211 is greater than the thickness dimension of the first lens portion 211. In the first position, the width dimension of the first lens portion 211 extends along the third direction y, and the optical axis of the first lens portion 211 extends along the first direction z, so as to increase the projection area of ​​the first lens portion 211 on the display module 10 when the first lens portion 211 is in the first position, so that more light emitted by the light-emitting unit 11 can pass through the first lens portion 211 along the first direction z. In the second position, the width dimension of the first lens portion 211 extends along the first direction z, and the optical axis of the first lens portion 211 extends along the third direction y, so as to reduce the projection area of ​​the first lens portion 211 on the display module 10 when the first lens portion 211 is in the second position, thereby reducing the obstruction of the light-emitting unit 11 by the first lens portion 211 when it is in the second position, which is beneficial to increasing the aperture ratio of the display panel 100 provided in the embodiment of this application.

[0092] In some embodiments provided in this application, the driving component 23 can generate a first electric field and a second electric field in the inner cavity 001. The first electric field extends along a first direction z and is used to drive the rotating body 21 to rotate to a first position. The second electric field extends along a third direction y, which is orthogonal to the first direction z and orthogonal to the second direction x. The second electric field is used to drive the rotating body 21 to rotate to a second position.

[0093] In some embodiments, the first lens portion 211 and / or the second lens portion 212 are charged, so that the first lens portion 211 and / or the second lens portion 212 can be subjected to force in a directional electric field to generate directional movement. The electric field force on the first lens portion 211 and / or the second lens portion 212 is transformed into the torque of the rotating body 21 through the lever action, thereby driving the rotating body 21 to rotate.

[0094] The first electric field is used to apply an electric field force along the first direction z toward or away from the display module 10 to the first lens section 211, so as to drive the first lens section 211 to move to any side of the second lens section 212 in the first direction z (i.e., the rotating body 21 is in the first position), so that the outline of the orthogonal projection of the first lens section 211 in the first direction z surrounds the orthogonal projection of the light-emitting unit 11 in the first direction z.

[0095] The second electric field is used to apply an electric field force to the first lens section 211 toward any side of the third direction y, so as to drive the first lens section 211 to move to any side of the second lens section 212 in the third direction y (i.e., the rotating body 21 is in the second position), so that the orthographic projection of the first lens section 211 in the first direction z is misaligned with the orthographic projection of the light-emitting unit 11 in the first direction z.

[0096] Therefore, by generating electric fields in different directions in the inner cavity 001 to drive the rotating body 21 to rotate between the first position and the second position, the driving component 23 drives the rotating body 21 to rotate without contacting the rotating body 21. The driving component 23 can be located outside the inner cavity 001, reducing the interference of the driving component 23 on the light transmittance of the refractive module 20.

[0097] In other embodiments, the first lens portion 211 and / or the second lens portion 212 are magnetic, and the drive assembly 23 is used to generate a first magnetic field extending along a first direction z and a second magnetic field extending along a third direction y in the inner cavity 001, thereby driving the rotating body 21 to move between a first position and a third position.

[0098] In some embodiments provided in this application, at least a portion of the first lens portion 211 is positively or negatively charged, so that the first lens portion 211 can rotate to a first position under a first electric field and to a second position under a second electric field.

[0099] In some embodiments, the surface of the first lens portion 211 away from the rotating body 21 carries a positive or negative charge.

[0100] In other embodiments, the material of the first lens portion 211 carries either a positive or negative charge.

[0101] Therefore, the first lens portion 211 carries a charge, so that the first electric field and the second electric field can generate an electric force on the first lens portion 211, thereby driving the rotating body 21 to rotate in the inner cavity 001 through the electric force received by the first lens portion 211.

[0102] In some embodiments provided in this application, at least a portion of the second lens portion 212 is positively or negatively charged, so that the rotating body 21 can rotate to a first position under a first electric field and to a second position under a second electric field.

[0103] In some embodiments, the surface of the second lens portion 212 away from the first lens portion 211 carries a positive or negative charge.

[0104] In other embodiments, the material of the second lens portion 212 is either positively or negatively charged.

[0105] Therefore, the second lens portion 212 is charged so that the first electric field and the second electric field can generate an electric force on the second lens portion 212, thereby driving the rotating body 21 to rotate in the inner cavity 001 by the electric force received by the second lens portion 212.

[0106] In some embodiments provided in this application, the end of the first lens portion 211 away from the second lens portion 212 carries either a positive charge or a negative charge, and the end of the second lens portion 212 away from the first lens portion 211 carries the other of a positive charge or a negative charge.

[0107] Thus, the first lens portion 211 and the second lens portion 212 carry opposite charges, so that the first electric field and the second electric field can generate opposite electric field forces on the first lens portion 211 and the second lens portion 212, thereby driving the rotating body 21 to rotate in the inner cavity 001 by the electric field force jointly experienced by the first lens portion 211 and the rotating body 21.

[0108] In some embodiments, the first lens portion 211 carries a positive charge, the second lens portion 212 is non-electric, and the first electric field extends along a first direction z toward one side of the display module 10. In a first position, the first lens portion 211 is located on the side of the second lens portion 212 toward the display module 10.

[0109] In some embodiments, the first lens portion 211 carries a positive charge, the second lens portion 212 is non-electric, and the first electric field extends along a first direction z away from the display module 10. In a first position, the first lens portion 211 is located on the side of the second lens portion 212 away from the display module 10.

[0110] In some embodiments, the first lens portion 211 carries a negative charge, the second lens portion 212 is non-electric, and the first electric field extends along a first direction z toward one side of the display module 10. In a first position, the first lens portion 211 is located on the side of the second lens portion 212 opposite to the display module 10.

[0111] In some embodiments, the first lens portion 211 carries a negative charge, the second lens portion 212 is non-electric, and the first electric field extends along a first direction z away from the display module 10. In a first position, the first lens portion 211 is located on the side of the second lens portion 212 facing the display module 10.

[0112] In some embodiments, the second lens portion 212 carries a positive charge, the first lens portion 211 is non-electric, and the first electric field extends along a first direction z toward one side of the display module 10. In a first position, the first lens portion 211 is located on the side of the second lens portion 212 away from the display module 10.

[0113] In some embodiments, the second lens portion 212 carries a positive charge, the first lens portion 211 is non-electric, and the first electric field extends along a first direction z away from the display module 10. In a first position, the first lens portion 211 is located on the side of the second lens portion 212 facing the display module 10.

[0114] In some embodiments, the second lens portion 212 carries a negative charge, the first lens portion 211 is non-electric, and the first electric field extends along a first direction z toward one side of the display module 10. In a first position, the first lens portion 211 is located on the side of the second lens portion 212 toward the display module 10.

[0115] In some embodiments, the second lens portion 212 carries a negative charge, the first lens portion 211 is non-electric, and the first electric field extends along a first direction z away from the display module 10.

[0116] In some embodiments, the first lens portion 211 carries a positive charge, the second lens portion 212 is non-electric, and the second electric field extends along the third direction y side.

[0117] In some embodiments, the first lens portion 211 carries a positive charge, the second lens portion 212 is non-electric, and the second electric field extends along the third direction y to the other side.

[0118] In some embodiments, the first lens portion 211 carries a negative charge, the second lens portion 212 is non-electric, and the second electric field extends along the third direction y side.

[0119] In some embodiments, the first lens portion 211 carries a negative charge, the second lens portion 212 is non-electric, and the second electric field extends along the third direction y to the other side.

[0120] In some embodiments, the second lens portion 212 carries a positive charge, the first lens portion 211 is non-electric, and the second electric field extends along the third direction y side.

[0121] In some embodiments, the second lens portion 212 carries a positive charge, the first lens portion 211 is non-electric, and the second electric field extends along the third direction y to the other side.

[0122] In some embodiments, the second lens portion 212 carries a negative charge, the first lens portion 211 is non-electric, and the second electric field extends along the third direction y side.

[0123] In some embodiments, the second lens portion 212 carries a negative charge, the first lens portion 211 is non-electric, and the second electric field extends along the third direction y to the other side.

[0124] In some embodiments provided in this application, the surface of the first lens portion 211 opposite to the side of the second lens portion 212 is provided with a first coating 2111, the first coating 2111 having a negative charge, and the surface of the second lens portion 212 opposite to the side of the first lens portion 211 is provided with a second coating 2121, the second coating 2121 having a positive charge.

[0125] like Figure 2 and Figure 3 As shown, when the first lens portion 211 and the second lens portion 212 are subjected to the electric field force generated by the driving component 23, the electric field force on the first lens portion 211 and the second lens portion 212 is changed into the torque of the rotating body 21 through the lever action. Only the first coating 2111 and the second coating 2121 are charged, thereby increasing the lever arm of the torque of the rotating body 21 and increasing the speed at which the driving component 23 drives the rotating body 21 to rotate. This gives the display panel 100 provided in this application embodiment the advantage of rapid response when adjusting the 2D / 3D display mode.

[0126] In some embodiments provided in this application, the thickness of the first coating 2111 is smaller than the thickness of the second coating 2121. This reduces the influence of the first coating 2111 on the light transmitted through the first lens portion 211.

[0127] In some embodiments provided in this application, such as Figure 2 and Figure 3 As shown, the refraction module 20 includes a first cover plate 24a and a second cover plate 24b that are parallel to each other and spaced apart along the first direction z. The second cover plate 24b is located between the first cover plate 24a and the display module 10, and an inner cavity 001 is formed between the first cover plate 24a and the second cover plate 24b.

[0128] The drive assembly 23 includes a first electrode 231 and a second electrode 232 arranged opposite to each other along the third direction y. The first electrode 231 and the second electrode 232 are located between the first cover plate 24a and the second cover plate 24b, and the first electrode 231 and the second electrode 232 are respectively located on both sides of the inner cavity 001 in the third direction y.

[0129] One of the first electrode 231 and the second electrode 232 is connected to the positive terminal of the DC power supply, and the other of the first electrode 231 and the second electrode 232 is connected to the negative terminal of the DC power supply, thereby generating a second electric field extending in the third direction y through the first electrode 231 and the second electrode 232.

[0130] The drive assembly 23 includes a third electrode 233 and a fourth electrode 234 arranged opposite to each other along the first direction z. The third electrode 233 is disposed on the surface of the first cover plate 24a facing the second cover plate 24b, and the second electrode 232 is disposed on the surface of the second cover plate 24b facing the first cover plate 24a. The inner cavity 001 is located between the third electrode 233 and the fourth electrode 234.

[0131] One of the third electrode 233 and the fourth electrode 234 is connected to the positive terminal of the DC power supply, and the other of the third electrode 233 and the fourth electrode 234 is connected to the negative terminal of the DC power supply, thereby generating a first electric field extending along the first direction z through the third electrode 233 and the fourth electrode 234.

[0132] In some embodiments provided in this application, such as Figure 2 and Figure 3 As shown, a first insulating layer 25a is provided on the side of the first cover plate 24a facing the second cover plate 24b, and the first insulating layer 25a covers the side of the third electrode 233 facing the inner cavity 001. A second insulating layer 25b is provided on the side of the second cover plate 24b facing the first cover plate 24a, and the second insulating layer 25b covers the side of the fourth electrode 234 facing the inner cavity 001.

[0133] Thus, the first insulating layer 25a and the second insulating layer 25b can generate a first electric field between the third electrode 233 and the fourth electrode 234 while insulating the third electrode 233, the fourth electrode 234 and the filler 22 from each other, thereby preventing the third electrode 233 and the fourth electrode 234 from partially ionizing the filler 22 and thus affecting the rotation of the rotating body 21.

[0134] In some embodiments provided in this application, such as Figure 2 and Figure 3 As shown, a first light-shielding layer 26 is provided on the side of the first cover plate 24a facing the second cover plate 24b. The first light-shielding layer 26 has a first opening 261. The orthographic projection of the light-emitting unit 11 in the first direction z is located within the orthographic projection of the first opening 261 in the first direction z. In the second position, the orthographic projection of the first lens part 211 in the first direction z is located within the outline of the orthographic projection of the first light-shielding layer 26 in the first direction z.

[0135] The light transmittance of the first light-shielding layer 26 is less than or equal to 5%. On the one hand, the first light-shielding layer 26 blocks the scattered light emitted by the light-emitting unit 11 and blocks the light dissipated by the filler 22 and the rotating body 21, thereby improving the resolution of the display panel 100 provided in this application embodiment. On the other hand, in the second position, the first lens portion 211 is blocked by the first light-shielding layer 26, so that only the portion of the light emitted by the light-emitting unit 11 along the first direction z that passes through the second lens portion 212 can be conducted from the first opening 261 to the light-emitting side of the display panel 100.

[0136] In some embodiments provided in this application, such as Figure 2 and Figure 3 As shown, the second cover plate 24b is provided with a second light-shielding layer 27 on the side facing the first cover plate 24a. The second light-shielding layer 27 is provided with a second opening 271. The orthographic projection of the light-emitting unit 11 in the first direction z is located within the orthographic projection of the second opening 271 in the first direction z. In the second position, the orthographic projection of the first lens part 211 in the first direction z is located within the outline of the orthographic projection of the first light-shielding layer 26 in the first direction z.

[0137] The light transmittance of the second light-shielding layer 27 is less than or equal to 5%, thereby blocking the scattered light emitted by the light-emitting unit 11 through the second light-shielding layer 27, preventing the scattered light emitted by the light-emitting unit 11 from being dissipated by the filler 22 and the rotating body 21 and then conducted from the first opening 261 to the light-emitting side of the display panel 100, thereby improving the resolution of the display panel 100 provided in this application embodiment.

[0138] In some embodiments, the first light-shielding layer 26 is located between the first insulating layer 25a and the first cover plate 24a, and the second light-shielding layer 27 is located between the second insulating layer 25b and the second cover plate 24b.

[0139] In some embodiments provided in this application, a first isolation member 28 and a second isolation member 29 are provided between the first cover plate 24a and the second cover plate 24b, arranged along the third direction y. The first isolation member 28 is connected between the first cover plate 24a and the second cover plate 24b, and the second isolation member 29 is connected between the first cover plate 24a and the second cover plate 24b. An inner cavity 001 is formed between the first isolation member 28 and the second isolation member 29.

[0140] like Figure 2 and Figure 3 As shown, the inner cavity 001 is formed by the first isolation member 28, the first cover plate 24a, the second isolation member 29, and the second cover plate 24b. By setting multiple alternating first isolation members 28 and second isolation members 29 in the third direction y, multiple inner cavities 001 can be formed between the first cover plate 24a and the second cover plate 24b in the third direction y.

[0141] In some embodiments provided in this application, such as Figure 2 and Figure 3 As shown, at least a portion of the first electrode 231 is located within the first isolator 28, and at least a portion of the second electrode 232 is located within the second isolator 29.

[0142] Thus, the first electrode 231 and the second electrode 232 are protected by the isolation element, preventing the first electrode 231 and the second electrode 232 from contacting the filler 22 and causing the filler 22 to oxidize.

[0143] In other embodiments (not shown in the figures), the first electrode 231 is located on the side of the first isolator 28 away from the inner cavity 001, and the second electrode 232 is located on the side of the second isolator 29 away from the inner cavity 001.

[0144] Thus, the first electrode 231 and the filler 22 are separated by the isolation member, and the second electrode 232 and the filler 22 are separated by the isolation member, so as to avoid the first electrode 231 and the second electrode 232 from contacting the filler 22 and causing the filler 22 to oxidize.

[0145] In some embodiments, the insulating element is a light-shielding material with a light transmittance of less than or equal to 5%.

[0146] The display device provided in the embodiments of this application is described below.

[0147] The display device provided in this application embodiment includes the display panel 100 provided in this application embodiment. Since the display panel 100 provided in this application embodiment can simultaneously realize 2D display of a part area and 3D display of a part area, the display device provided in this application embodiment can simultaneously realize 2D display of a part area and 3D display of a part area.

[0148] The above are merely preferred embodiments of this application and are 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.
