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 in a radial direction of the rotating body 21, a refractive index of the first lens portion 211 is different from a refractive index of the second lens portion 212, and the refractive index of the second lens portion 212 is the same as a refractive index of the filling body 22.

[0049] It should be noted that the refractive index of the first lens portion 211 is different from the refractive index of the second lens portion 212, that is, a 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; and the refractive index of the second lens portion 212 is the same as the refractive index of the filling body 22, that is, a difference between the refractive index of the second lens portion 212 and the refractive index of the filling body 22 is less than or equal to 5% of the refractive index of the second lens portion 212 or the refractive index of the filling body 22.

[0050] 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.

[0051] In some embodiments, as shown in Figure 2 and Figure 3 The inner cavity 001 is provided with one rotating body 21.

[0052] In other embodiments (not shown in the drawings), 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 in the third direction y.

[0053] In some embodiments (not shown in the figures), a portion of the inner cavity 001 is provided with a rotating body 21, and another portion of the inner cavity 001 is provided with a plurality of rotating bodies 21.

[0054] In some embodiments, as shown in Figure 2 and Figure 3 , 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 filling body 22 and the refractive index of the second lens portion 212.

[0055] In some other embodiments, as shown in Figure 4 , 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 filling body 22 and the refractive index of the second lens portion 212.

[0056] As shown in Figure 2 , in the first position, the first lens portion 211 is arranged one-to-one on the light-emitting side of the light-emitting unit 11 in the first direction z, that is, the first lens portion 211 is in the path of propagation of the light rays 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 contour of the orthographic projection of the first lens portion 211 in the first direction z, and the parallel light rays generated by the light-emitting unit 11 in the first direction z are refracted on both sides of the surface of the first lens portion 211 in the third direction y when passing through the first lens portion 211, so that a part of the parallel light rays generated by a part of the pixel units are refracted to the left eye of the user, and another part of the parallel light rays generated by another part of the pixel units are refracted to the right eye of the user, thereby realizing 3D display.

[0057] As shown in Figure 3 , in the second position, the orthographic projection of the light-emitting unit 11 in the first direction z is arranged in a staggered manner with the orthographic projection of the first lens portion 211 in the first direction z, that is, the first lens portion 211 is not in the direct propagation path of the light rays emitted by the light-emitting unit 11 at this time, and the parallel light rays generated by the light-emitting unit 11 in the first direction z do not directly pass through the first lens portion 211, but pass through the second lens portion 212 and the filling body 22 in the first direction z. Since the refractive index of the second lens portion 212 is the same as the refractive index of the filling body 22, the overall effect of the second lens portion 212 and the filling body 22 combined together on the light rays is close to that of a uniform and unbiased medium, and when the light rays generated by the light-emitting unit 11 pass through the boundary between the second lens portion 212 and the filling body 22, the boundary between the second lens portion 212 and the filling body 22 does not refract the parallel light rays, thereby realizing 2D display.

[0058] In some embodiments, as shown in Figure 2 and Figure 3As shown, the filling body 22 is liquid, the rotating body 21 is 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.

[0063] The refraction module 20 includes a plurality of driving assemblies 23, and the plurality of driving assemblies 23 are respectively used to drive the rotating body 21 to rotate between the first position and the second position.

[0064] In some embodiments, the refraction module 20 includes a plurality of inner cavities 001, and the driving assembly 23 can respectively drive the rotating body 21 in different inner cavities 001, so that different rotating bodies 21 are located at different positions, thereby making a part of light generated by the light emitting unit 11 refract to both sides of the third direction y by the first lens part 211 when the light passes through the refraction module 20 to realize 3D display, and another part of light generated by the light emitting unit 11 is still parallel light after passing through the refraction module 20 to realize 2D display.

[0065] In other embodiments, the refraction module 20 includes a single inner cavity 001, and the driving assembly 23 can respectively drive a plurality of rotating bodies 21 in the inner cavity 001, so that the plurality of rotating bodies 21 in the inner cavity 001 are located at different positions.

[0066] In some embodiments, the display panel 100 includes a first area and a second area, and the driving assembly 23 can adjust a plurality of rotating bodies 21 in the first area to the first position and adjust a plurality of rotating bodies 21 in the second area to the second position, so that the first area works in 3D display mode and the second area works in 2D display mode.

[0067] In some embodiments, the driving assembly 23 can individually drive each rotating body 21 to rotate.

[0068] In some embodiments, the driving assembly 23 is capable of driving the rotator 21 in each of the plurality of inner cavities 001 to rotate simultaneously, i.e., the positions of the plurality of rotators 21 in the inner cavities 001 are the same.

[0069] The display panel 100 provided by the embodiments of the present application drives the first lens portion 211 to move between the first position and the second position by the driving assembly 23. In the first position, the parallel light generated by the light emitting unit 11 passes through the first lens portion 211 and is refracted, and part of the refracted light is deflected to the left eye of the user, and another part of the refracted light is deflected to the right eye of the user, and 3D display is realized by the difference between the images of the two eyes of the user. In the second position, the first lens portion 211 avoids the parallel light generated by the light emitting unit 11, so that the parallel light generated by the light emitting unit 11 does not refract and deflect in the process of passing through the refraction module 20, thereby realizing 2D display.

[0070] The refraction module 20 provided by the embodiments of the present application has the beneficial effect that, compared with the prior art display panel which can only switch between the 2D display mode and the 3D display mode, the rotators 21 of the refraction module 20 provided by the embodiments of the present application are all located in the first position to make the display panel 100 realize complete 3D display, the rotators 21 of the refraction module 20 are all located in the second position to make the display panel 100 realize complete 2D display, and when part of the rotators 21 are located in the first position and part of the rotators 21 are located in the second position, the display panel 100 can realize 2D display in part of the area and 3D display in part of the area, so that the refraction module provided by the embodiments of the present application can make the display panel 100 realize 2D display in part of the area and 3D display in part of the area at the same time.

[0072] In some embodiments, the driving assembly 23 is capable of driving each of the rotators 21 to rotate individually.

[0073] In some embodiments, the driving assembly 23 is capable of driving the rotator 21 in each of the plurality of inner cavities 001 to rotate simultaneously, i.e., the positions of the plurality of rotators 21 in the inner cavities 001 are the same.

[0074] Therefore, by the driving assembly 23, part of the light generated by the light emitting unit 11 is refracted to both sides of the third direction y by the first lens portion 211 when passing through the refraction module 20 to realize 3D display, and another part of the light generated by the light emitting unit 11 is still parallel light after passing through the refraction module 20 to realize 2D display.

[0075] In addition, the driving assembly 23 is capable of driving all the rotating bodies 21 in the refraction module 20 to be located at the first position or the second position.
