FIG. 1 is a diagram of an optical system for processing a first S-polarized light according to an embodiment of the present application; fig. 2 is a light path diagram of an optical system for processing first P-polarized light according to an embodiment of the present application. The embodiment of the present application provides an optical system 1, as shown in fig. 1 and 2, the optical system 1 includes a spectroscopic element 11, a polarization processing structure 12, and a polarization selection device 13.
The light-splitting element 11 is configured to reflect the first S-polarized light onto the polarization-selection device 13 such that the polarization-selection device 13 reflects the first S-polarized light to form a first image P1 on the polarization-selection device 13 and transmit the first P-polarized light to the polarization-processing structure 12.
The polarization processing structure 12 adjusts the direction of the first P-polarized light, so that the first P-polarized light after the direction adjustment is projected to the polarization selection device 13 through the light splitting element 11, and the polarization selection device 13 transmits the first P-polarized light after the direction adjustment to form the second image P2.
The first S polarized light and the first P polarized light are display light rays of two adjacent frames of display pictures, and the first image P1 and the second image P2 are overlapped to realize 3D display.
The optical system 1 provided in this embodiment can reflect S polarized light and adjust P polarized light, so that the S polarized light and the P polarized light pass through the first image P1 and the second image P2 formed by the optical system 1 respectively, and superposition of the first image P1 and the second image P2 can provide a 3D viewing experience for a user.
Alternatively, as shown in fig. 1 and 2, in the optical system provided in this embodiment, the polarization selection device 13 transmits P polarized light and reflects S polarized light, and the material of the polarization selection device 13 includes metal or light-transmissive plastic. Specifically, when the polarization selection device 13 is made of light-transmitting plastic, not only the desired effect of the polarization selection device 13 but also the user can be made to view a real scene, thereby achieving the fusion of the 3D display screen and the real scene.
Alternatively, as shown in fig. 1 to 3, the spectroscopic element 11 includes a spectroscopic layer 111 and a support structure 112 connected to the spectroscopic layer, the spectroscopic layer 111 reflecting P-polarized light transmitted therethrough and S-polarized light, and the support structure 112 supporting the spectroscopic layer 111. Specifically, the support structure 112 is a transparent cube, and the spectroscopic layer 111 is disposed on a plane defined by two diagonal lines of the cube.
As shown in fig. 1 and 2, in the optical system 1 provided in the present embodiment, the polarization processing structure 12 includes a first component 121 and a second component 122; the first component 121 is configured to convert the first P-polarized light into the second S-polarized light, and reflect the second S-polarized light to the light splitting element 11, so that the light splitting element 11 reflects the second S-polarized light to the second component 122; the second component 122 is configured to convert the second S polarized light into second P polarized light, and reflect the second P polarized light to the light splitting element 11, so that the second P polarized light is projected to the polarization selection device 13 through the light splitting element 11 to form a second image P2.
Specifically, the first P-polarized light is transmitted through the spectroscopic layer 111 and then projected onto the first component 121, the first component 121 converts the first P-polarized light into the second S-polarized light and reflects the second S-polarized light, the reflected second S-polarized light is reflected by the spectroscopic layer 111 and then projected onto the second component 122, the second component 122 converts the second S-polarized light into the second P-polarized light and reflects the second P-polarized light, the reflected second P-polarized light irradiates onto the spectroscopic layer 111, and since the P-polarized light can transmit through the spectroscopic layer 111, the second P-polarized light (i.e., the first P-polarized light after the direction is changed) can transmit through the spectroscopic layer 111 and be projected onto the polarization selection device 13 to form the second image P2.
As shown in fig. 1 to 3, in the optical system 1 provided in the present embodiment, the first component 121 includes a first 1/4 slide 1211 and a first reflective layer 1212, the first 1/4 slide 1211 is located at a side of the spectroscopic element 11 away from the first S-polarized light incident surface a, and the first reflective layer 1212 is located at a side of the first 1/4 slide 1211 away from the spectroscopic element 11; the second assembly 122 includes a second 1/4 slide 1221 and a second reflective layer 1222, the second 1/4 slide 1221 being located on a side of the spectroscopic element 11 away from the first S-polarized light exit surface b, and the second reflective layer 1222 being located on a side of the second 1/4 slide 1221 away from the spectroscopic element 11.
Specifically, the first S-polarized light incident surface a and the first S-polarized light exit surface b are both surfaces of the support structure 112, the 1/4 glass slide functions to convert P-polarized light into S-polarized light, and the reflective layer functions to reflect the converted S-polarized light.
Further, the first reflective layer 1212 is a curved mirror and/or the second reflective layer 1222 is a curved mirror, and the curved mirror adjusts the focal plane of the first image P1 and/or the focal plane of the second image P2, so that the focal plane of the first image P1 and the focal plane of the second image P2 do not overlap. So can realize many focal plane 3D display effect, many focal plane's 3D display effect is more true than traditional 3D display, can promote user's viewing experience.
It should be noted that, the first reflective layer 1212 and the second reflective layer 1222 may be planar mirrors, and the planar mirrors may not be capable of adjusting focal planes of the first image P1 and the second image P2, so that only the conventional 3D display effect can be achieved.
Specifically, the center point of the spectroscopic layer 111, the center point of the first 1/4 slide 1211, and the center point of the first reflective layer 1212 are on the same line, and the center point of the spectroscopic layer 111, the center point of the second 1/4 slide 1221, and the center point of the second reflective layer 1222 are also on the same line, so that the display light is better processed.
Specifically, in the optical system shown in fig. 2, the first image P1 is located in the first focal plane F1, the second image P2 is located in the second focal plane F2, and the first focal plane F1 and the second focal plane F2 are parallel to each other, and it should be noted that, because the first image P1 and the second image P2 are formed by display light of two adjacent frames of display pictures respectively, the first image P1 and the second image P2 do not exist at the same time in reality, but only because the first image P1 and the second image P2 are seen by human eyes at the same time due to the persistence effect of vision, and on this basis, the superposition of the first image P1 and the second image P2 forms a 3D display effect.
Based on the same inventive concept, an embodiment of the present application provides a display device, as shown in fig. 1 and 2, including:

For example, the lens group 4 in the display device shown in fig. 4 includes the first lens 41 and the second lens 42, and parameters of the first lens 41 and the second lens 42 may be the same, or the first lens 41 and the second lens 42 with different parameters may be selected according to actual needs.
Specifically, the focal point of the lens, the center point of the image source 2, and the center point of the spectroscopic element 11 are positioned on the same straight line, and the sizes of the first image P1 and the second image P2 can be adjusted by adjusting the positions of the lens group 4 on the above straight line, thereby adjusting the size of the 3D image seen by the user.

The image source 2 in this embodiment adopts high-frequency switching, so that the last frame image and the current frame image reserved by human eyes are overlapped to realize the 3D display effect.
As shown in fig. 5, the display device provided in this embodiment further includes a vision acquisition system and an adjustment system. The vision acquisition system is used for acquiring information of eyes 3 of a user; the adjusting system is connected to the optical system 1 and the image source 2, and is configured to adjust a distance between the optical system 1 and the image source 2, a distance between the optical system 1 and the polarization selection device 13, and an angle between the display light and the horizontal plane according to the binocular information.
Specifically, the distance between the optical system 1 and the image source 2 refers to the distance between the spectroscopic element 11 in the optical system 1 and the image source 2, and the distance between the optical system 1 and the display surface refers to the distance between the spectroscopic element 11 in the optical system 1 and the polarization selection device 13. In addition, for example, the center of the image source 2 and the center of the spectroscopic element 11 are located on the same straight line, and the spectroscopic system needs to be synchronously rotated while adjusting the included angle between the display light (perpendicular to the plane in which the image source 2 is located) and the horizontal plane.
