[0039] In an exemplary embodiment, the display panel 30 may be an organic light-emitting diode (OLED) display panel, a liquid crystal display panel (LCD) or a micro light-emitting diode (Micro LED) display panel. This application takes the display panel 30 as an OLED display panel as an example for description.

Those skilled in the art may make corresponding supplements based on the specific type and actual functions of the display device 1, which will not be repeated here.

[0042] See also Figures 2 to 4 , Figure 2 1 is a schematic diagram of a first partial top view structure of a display panel disclosed in the second embodiment of the present application, Figure 3 for Figure 2 The cross-sectional schematic diagram of the display panel in the first display mode along the III-III direction is shown, Figure 4 for Figure 2 The cross-sectional schematic diagram of the display panel shown in the second display mode along the III-III direction. In the embodiment of the present application, the display panel 30 includes a first light emitting side 30a and a second light emitting side 30b that are relatively arranged, and the first light emitting side 30a and the second light emitting side 30b are both exposed from the housing 10, and the first light emitting side 30a and / or the second light emitting side 30b emit light, that is, the first light emitting side 30a and / or the second light emitting side 30b display a picture, and the pictures displayed by the first light emitting side 30a and the second light emitting side 30b may be the same or different. Among them, the first light emitting side 30a and / or the second light emitting side 30b refers to one of the three possibilities: the first light emitting side 30a, the second light emitting side 30b, the first light emitting side 30a and the second light emitting side 30b. The display panel 30 in the first display mode and the display panel 30 in the second display mode are both double-sided displays, and the difference between the display panel 30 in the first display mode and the display panel 30 in the second display mode lies in that the light emitting area of ​​the first light emitting side 30a of the display panel 30 in the first display mode is different from the light emitting area of ​​the first light emitting side 30a of the display panel 30 in the second display mode, and the light emitting area of ​​the second light emitting side 30b of the display panel 30 in the first display mode is different from the light emitting area of ​​the second light emitting side 30b of the display panel 30 in the second display mode.

[0043] In the embodiment of the present application, the display panel 30 includes a driving component 31, a light emitting component 32, a polarization adjustment component 34, and an optical component 35 which are sequentially stacked. That is, the light emitting component 32 is arranged on one side of the driving component 31, the polarization adjustment component 34 is arranged on the side of the light emitting component 32 facing away from the driving component 31, and the optical component 35 is arranged on the side of the polarization adjustment component 34 facing away from the light emitting component 32. The first light emitting side 30a is the side of the optical component 35 facing away from the polarization adjustment component 34, and the second light emitting side 30b is the side of the driving component 31 facing away from the light emitting component 32. The driving component 31 is used to drive the light emitting component 32 to emit natural light, and the polarization adjustment component 34 is used to receive the natural light emitted by the light emitting component 32, and part of the polarization adjustment component 34 converts the natural light into a first polarized light of polarized light, and part of the polarization adjustment component 34 converts the natural light into a second polarized light of polarized light. The optical component 35 has a light transmission axis and a reflection axis, and the direction of the light transmission axis is different from the direction of the reflection axis. The polarization direction of the first polarized light is parallel to the light transmission axis, and the light transmission axis of the optical component 35 is used to transmit the first polarized light to the first light exiting side 30a, and the first light exiting side 30a emits light. The polarization direction of the second polarized light is parallel to the reflection axis, and the reflection axis of the optical component 35 is used to reflect the second polarized light to the second light exiting side 30b, and the second light exiting side 30b emits light. That is, the polarization direction of the first polarized light is different from the polarization direction of the second polarized light.

[0044] In an exemplary embodiment, see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the principle of light transmission of an optical component disclosed in the second embodiment of the present application. Figure 6 The schematic diagram of the principle of the optical component being opaque according to the second embodiment of the present application is shown in FIG. The polarization direction of the first polarized light is parallel to the light transmission axis, and thus the first polarized light can pass through the optical component 35. The polarization direction of the second polarized light is not parallel to the light transmission axis, and thus the second polarized light cannot pass through the optical component 35.

[0045] It can be understood that the present application converts the light of natural light into the first polarized light of polarized light through part of the polarization adjustment component 34, so that the first polarized light can be transmitted to the first light-emitting side 30a through the light transmission axis of the optical component 35, and then the first light-emitting side 30a can display the picture. At the same time, the light of natural light is also converted into the second polarized light of polarized light through part of the polarization adjustment component 34, so that the light transmission axis of the optical component 35 can reflect the second polarized light to the second light-emitting side 30b, and then the second light-emitting side 30b can display the picture. Therefore, the display device 1 with double-sided display is realized by the polarization adjustment component 34, and the display device 1 of the present application has only one display panel 30, and the display panel 30 has only one light-emitting component 32 that provides the light, so that the internal structure of the display device 1 is relatively simple, saving costs. At the same time, the display panel 30 only adds a layer structure of the polarization adjustment component 34 and the optical component 35, so that the double-sided display of the display panel 30 can be realized, which is conducive to the thinness of the display device 1.

[0046] It can also be understood that when ambient light is emitted toward the optical component 35 , the reflection axis of the optical component 35 will also reflect the ambient light whose polarization direction is parallel to the reflection axis of the optical component 35 , so that the first light output side 30 a has a mirror function.

[0047] In an exemplary embodiment, the transmission axis of the optical component 35 is perpendicular to the reflection axis, that is, the polarization direction of the first polarized light is perpendicular to the polarization direction of the second polarized light.

[0048] In the implementation mode of this application, please refer to Figure 2 The polarization adjustment component 34 includes a plurality of first polarization adjustment areas a and a plurality of second polarization adjustment areas b, and the plurality of first polarization adjustment areas a and the plurality of second polarization adjustment areas b are arranged alternately in sequence along the first direction 001, that is, the plurality of first polarization adjustment areas a and the plurality of second polarization adjustment areas b can be arranged in the order of: the first polarization adjustment area a, the second polarization adjustment area b, the first polarization adjustment area a, the second polarization adjustment area b, ..., the first polarization adjustment area a, the second polarization adjustment area b along the first direction 001. The plurality of first polarization adjustment areas a and the plurality of second polarization adjustment areas b both extend along the second direction 002, wherein the first direction 001 is perpendicular to the second direction 002.

[0049] In an exemplary embodiment, the first polarization adjustment region a is connected to the adjacent second polarization adjustment region b, and the second polarization adjustment region b is connected to the adjacent first polarization region a.

[0050] In an exemplary embodiment, the first light-emitting side surface 30 a and the second light-emitting side surface 30 b display the same image.

[0051] In an exemplary embodiment, the first polarization adjustment region a corresponds to the position of the plurality of light-emitting elements of the light-emitting assembly 32, that is, in the direction in which the light-emitting assembly 32 points to the optical assembly 35, the first polarization adjustment region a is located above the light-emitting elements of the light-emitting assembly 32. The second polarization adjustment region b is staggered from the position of the plurality of light-emitting elements of the light-emitting assembly 32, that is, in the direction in which the light-emitting assembly 32 points to the optical assembly 35, the second polarization adjustment region b is not located above the light-emitting elements of the light-emitting assembly 32.

[0052] In the implementation mode of this application, please refer to Figure 3 , the plurality of first polarization adjustment regions a are used to convert the light of natural light into the first polarized light, and the second polarization adjustment regions b are used to convert the light of natural light into the second polarized light; or, refer to Figure 4 The plurality of first polarization adjustment regions a are used to convert the light of natural light into the second polarized light, and the second polarization adjustment regions b are used to convert the light of natural light into the first polarized light.

[0053] It can be understood that the display area of ​​the display panel 30 includes multiple first display areas and multiple second display areas, and the position of one of the first display areas corresponds to the position of one of the first polarization adjustment areas a, and the position of one of the second display areas corresponds to the position of one of the second polarization adjustment areas b. That is, the orthographic projection of one of the first polarization adjustment areas a on the driving component 31 coincides with the orthographic projection of one of the first display areas on the driving component 31, and the orthographic projection of the second polarization adjustment area b on the driving component 31 coincides with the orthographic projection of the second display area on the driving component 31. Both the first light emitting side 30a and the second light emitting side 30b are provided with multiple first display areas and multiple second display areas. Please refer to Figure 3 , the plurality of first polarization adjustment areas a convert the light of natural light into the first polarized light, the plurality of first display areas on the first light exiting side 30a emit light, the second polarization adjustment areas b convert the light of natural light into the second polarized light, the plurality of second display areas on the second light exiting side 30b emit light, that is, the display panel 30 is in the first display mode. Please refer to Figure 4, multiple first polarization adjustment areas a convert the natural light into the second polarized light, multiple first display areas on the second light emitting side 30b emit light, and the second polarization adjustment areas b convert the natural light into the first polarized light, and multiple second display areas on the first light emitting side 30a emit light, that is, the display panel 30 is in the second display mode.

[0054] In the implementation mode of this application, please refer to Figure 3 and Figure 4 , the polarization adjustment component 34 includes a solution 341 and a plurality of quantum elements 342. The solution 341 is disposed between the light emitting component 32 and the optical component 35, and the plurality of quantum elements 342 are dispersed in the solution 341. The solution 341 is used to suspend the plurality of quantum elements 342, and the plurality of quantum elements 342 located in the first polarization adjustment region a are used to convert the light of natural light into the first polarized light, and the plurality of quantum elements 342 located in the second polarization adjustment region b are used to convert the light of natural light into the second polarized light; or, the plurality of quantum elements 342 located in the first polarization adjustment region a are used to convert the light of natural light into the second polarized light, and the plurality of quantum elements 342 located in the second polarization adjustment region b are used to convert the light of natural light into the first polarized light.

[0055] In an exemplary embodiment, the solution 341 may include one or more organic solvents such as diethylene glycol methyl ethyl ether, methyl ethyl ketone, or methyl isobutyl ketone, which is not specifically limited in the present application.

[0056] In an exemplary embodiment, the shape of the quantum element 342 may be an ellipsoid, and the emission and absorption spectra of the quantum element 342 are size-dependent, so the quantum element 342 can convert natural light into polarized light. The quantum element 342 has a long axis, and the quantum element 342 makes the polarization direction of the polarized light passing through the quantum element 342 parallel to the long axis direction of the quantum element 342, and then the quantum element 342 can convert the light of natural light into the first polarized light and the second polarized light. When the long axis direction of the quantum element 342 changes, the polarization direction of the polarized light passing through the quantum element 342 also changes accordingly. Among them, the plane of deflection of the quantum element 342 is perpendicular to the thickness direction of the display panel 30, and the thickness direction of the display panel 30 is the direction in which the drive component 31 points to the optical component 35.

[0057] In an exemplary embodiment, the material of the quantum element 342 includes one or more semiconductor materials such as cadmium selenide (CdSe), cadmium telluride (CdTe), cadmium sulfide (CdS), zinc selenide (ZnSe), etc., and the present application does not impose any specific limitation on this.

[0058] In one embodiment of the present application, please refer to Figure 3 The polarization adjustment component 34 further includes a plurality of first electrodes 343 and a plurality of second electrodes 344. The long axes of the plurality of quantum elements 342 in the first polarization adjustment region a are parallel to the light transmission axis of the optical component 35, and the first electrodes 343 and the second electrodes 344 are arranged spaced apart in each of the second polarization adjustment regions b. The first electrodes 343 and the second electrodes 344 are used to form a preset electric field for driving the deflection of the plurality of quantum elements 342 in the second polarization adjustment region b, so that the long axes of the plurality of quantum elements 342 in the second polarization adjustment region b are parallel to the light reflection axis of the optical component 35.

[0059] It can be understood that the long axes of the multiple quantum elements 342 in the first polarization adjustment area a are parallel to the light transmission axis of the optical component 35, and the multiple quantum elements 342 in the first polarization adjustment area a convert the light of natural light into the first polarized light, and then the first display area of ​​the first light exit side 30a emits light. The long axes of the multiple quantum elements 342 in the second polarization adjustment area b are parallel to the reflection axis of the optical component 35, so that the multiple quantum elements 342 in the second polarization adjustment area b can convert the light of natural light into the second polarized light, and then the reflection axis of the optical component 35 can reflect the second polarized light to the second light exit side 30b, and then the second display area of ​​the second light exit side 30b emits light.

[0060] It can also be understood that when the preset electric field is not formed, the long axes of the multiple quantum elements 342 in the first polarization adjustment area a and the second polarization adjustment area b are parallel to the light transmission axis of the optical component 35, so that the multiple quantum elements 342 in the first polarization adjustment area a and the second polarization adjustment area b convert the natural light into the first polarized light, and then the first display area and the second display area of ​​the first light emitting side 30a emit light, and the second light emitting side 30b does not emit light.

[0061] In another embodiment of the present application, please refer to Figure 4, the long axes of the multiple quantum elements 342 in the second polarization adjustment area b are parallel to the light transmission axis of the optical component 35, and each of the first polarization adjustment areas a is provided with the first electrode 343 and the second electrode 344 spaced apart from each other, and the first electrode 343 and the second electrode 344 are used to form a preset electric field for driving the deflection of the multiple quantum elements 342 in the first polarization adjustment area a, so that the long axes of the multiple quantum elements 342 in the first polarization adjustment area a are parallel to the reflection axis of the optical component 35.
