The display device 10 includes a screen 100, where the screen 100 includes a carrier layer 101 and a functional layer 102 disposed on one side of the carrier layer 101, and the functional layer 102 is carried on the carrier layer 101. The functional layer 102 includes a plurality of first light reflecting portions 1021 and a plurality of second light reflecting portions 1022. The plurality of first light reflecting portions 1021 and the plurality of second light reflecting portions 1022 are arranged alternately. The plurality of first light reflecting portions 1021 and the plurality of second light reflecting portions 1022 are both disposed obliquely with respect to the carrier layer 101, and when an angle between the first light reflecting portions 1021 and a predetermined direction is an obtuse angle, an angle between the second light reflecting portions 1022 and the predetermined direction is an acute angle. The first light reflection part 1021 is used for reflecting the first light ray 201, and the second light reflection part 1022 is used for reflecting the second light ray 211. Note that a plurality means a number greater than or equal to two.

It can be understood that when the two eyes of a person watch the same object, due to the certain distance between the two eyes, the scenes watched by the two eyes are not completely consistent, and the scenes obtained by the two eyes actually have slight differences.

In the present embodiment, the first light reflecting portion 1021 and the second light reflecting portion 1022 are both disposed in an inclined manner relative to the supporting layer 101, and the degree of the inclination is determined according to the incident direction of the provided first light 201 and second light 211, so that the propagation path of the reflected light of the first light 201 and second light 211 can reach a predetermined position.

When the angle between the first light reflecting portion 1021 and the predetermined direction is an obtuse angle, the angle between the second light reflecting portion 1022 and the predetermined direction is an acute angle. It should be noted that the preset direction is a positive direction of the X axis, and the obtuse angle described herein is an angle formed between the direction pointed by the first light reflecting portion 1021 when extending in the direction away from the carrying layer 101 and the preset direction; the acute angle described herein is an angle between a direction in which the second light reflecting portion 1022 is directed when extending away from the carrier layer 101 and a predetermined direction. Therefore, when the adjacent first light reflection part 1021 and the second light reflection part 1022 extend in a direction away from the carrier layer 101, the directions pointed by the adjacent first light reflection part 1021 and the adjacent second light reflection part 1022 are opposite, that is, propagation paths of the first light ray 201 and the second light ray 211 after being reflected by the adjacent first light reflection part 1021 and the adjacent second light reflection part 1022 are opposite, the first light ray 201 and the second light ray 211 are separated after being reflected, and thus converge to two different positions, where the two different positions are positions of two eyes, so that two eyes can obtain different images.

One of the main functions of the first light reflection portion 1021 is to reflect the first light 201, optionally, the first light reflection portion 1021 includes a substrate portion 1021a and a transparent portion 1021b, the substrate portion 1021a is disposed on one side of the carrier layer 101, the transparent portion 1021b is disposed on one side of the substrate portion 1021a away from the carrier layer 101, the substrate portion 1021a is used to reflect the first light 201, the transparent portion 1021b is used to protect the substrate portion 1021a, the substrate portion 1021a may be, but not limited to, made of aluminum, the aluminum metal has a strong light reflection capability, and the 3D display quality may be improved.

The display device 10 of the application reflects the first light 201 and the second light 211 respectively through the first light reflection parts 1021 and the second light reflection parts 1022 arranged at intervals, so that the first light 201 and the second light 211 are received by the eyes of a user respectively, and the brain simulates a corresponding 3D image according to the first light 201 and the second light 211 received by the eyes, thereby realizing a naked eye 3D effect.

The first light reflecting part 1021 and the second light reflecting part 1022 which are adjacent to each other are connected end to end.

The adjacent first light reflection unit 1021 and the second light reflection unit 1022 may be directly connected or indirectly connected, and in the present embodiment, the first light reflection unit 1021 and the adjacent second light reflection unit 1022 are schematically described as being directly connected. It can be understood that, in order to better present the image effect, the first light beam 201 and the second light beam 211 are to be spread over the whole display area, the display area refers to an area where the image is presented on the screen 100 and also an area that can be seen by the user, and the adjacent first light reflection part 1021 and the second light reflection part 1022 are directly connected in an ending manner, so that the screen 100 can more fully receive the first light beam 201 and the second light beam 211 and reflect the first light beam 201 and the second light beam 211 to a designated position, which is a position where human eyes are located, thereby better presenting the 3D effect and improving the 3D display quality.

Referring to fig. 4, fig. 4 is a partially enlarged view of a region a in fig. 1 according to another embodiment of the present disclosure. The carrier layer 101 includes a carrier body 1012 and a plurality of protrusions 1011, all of the protrusions 1011 are closely arranged on the surface of the carrier body 1012, and two opposite sides of the protrusions 1011 respectively carry the first light reflecting portion 1021 and the second light reflecting portion 1022.

It can be understood that the first light reflecting part 1021 and the second light reflecting part 1022 are core parts for realizing naked-eye 3D effect, and the 3D display quality is directly affected by the first light reflecting part 1021 and the second light reflecting part 1022, so that it is required that the first light reflecting part 1021 and the second light reflecting part 1022 cannot be damaged by the outside or the positions of the first light reflecting part 1021 and the second light reflecting part 1022 relative to other parts are changed. In this embodiment, the carrier layer 101 further includes a carrier body 1012 and a plurality of protrusions 1011, all the protrusions 1011 are closely arranged on the surface of the carrier body 1012, and the first light reflecting portion 1021 and the second light reflecting portion 1022 are correspondingly disposed on two sides of the protrusions 1011, so that the first light reflecting portion 1021 and the second light reflecting portion 1022 form a carrier, and the first light reflecting portion 1021 and the second light reflecting portion 1022 are ensured not to be easily deformed or damaged under the action of an external force. Optionally, the protrusion 1011 may be made of an elastic material, and the elastic material has a proper denaturation capability, so as to absorb an external acting force; the protrusion 1011 may also be made of a hard material, which has a higher load-bearing capacity.

Referring to fig. 1 to 2, fig. 2 is a partially enlarged view of a region a in fig. 1 according to an embodiment of the present disclosure. The carrier layer 101 includes a carrier body 1012, the carrier body 1012 is used for carrying the first light reflecting portion 1021 and the second light reflecting portion 1022, and the carrier body 1012, the first light reflecting portion 1021, and the second light reflecting portion 1022 form a gap space.

In this embodiment, the first light reflection part 1021 and the second light reflection part 1022 are fixed by the supporting body 1012, and the supporting body 1012, the first light reflection part 1021, and the second light reflection part 1022 form a gap space, so that the weight of the screen 100 is reduced, the requirement of light weight is satisfied, and the screen is more convenient to carry or accommodate.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating a derivation principle of an inclination angle formed by the first light reflecting portion relative to the supporting layer according to the present application. The inclination angles of the first light reflecting part 1021 and the carrier layer 101 arranged from one side of the screen 100 toward the other side opposite to the one side are sequentially changed.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating a principle of deriving an inclination angle formed by the second light reflecting portion relative to the carrier layer according to the present disclosure. The inclination angles of the second light reflecting part 1022 and the carrier layer 101, which are arranged from one side of the screen 100 toward the other side opposite to the one side, sequentially change.

It can be understood that, if the two eyes of the person have a certain distance, all the light reflected back on the screen 100 are captured by the two eyes at the same time, the 3D effect cannot be presented, and therefore, different light needs to be reflected to the two eyes respectively to see the 3D image. The reflection of the light is regular, and the propagation path of the light is changed according to the regular pattern, so that different light can be propagated to different positions. In the present embodiment, the inclination angles of the first light reflecting part 1021 and the second light reflecting part 1022 with respect to the carrier layer 101 have a certain mathematical relationship with the positions of the light source, the eyes, and the screen 100, and the following description is schematically made with reference to fig. 5 to 6.

Referring to fig. 5, the first projector 200 emits a first light 201 toward the screen 100, and the first light 201 is reflected to the first human eye 2 by the first light reflection portion 1021, where α is a projection angle of the first projector 200, β is an inclination angle of the first light reflection portion 1021 relative to the carrying layer 101, γ is a reflection angle of the first light 201 projected by the first projector 200 reflected into the first human eye 2, H is a distance from the carrying layer 101 to the first human eye 2, a is a horizontal distance from the first projector 200 to the first human eye 2, and B is a horizontal distance from the first human eye 2 to a reflection point of the first light reflection portion 1021, and an inclination angle of the first light reflection portion 1021 relative to the carrying layer 101 is derived from the angles and the distances, and a mathematical relationship expression is:

β＝90°-α-γ/2

α＝arctg(H/(A+B))*180°/π

γ＝90°-α-arctg(B/H)*180°/π

through the above formula, the inclination angle of the first light reflecting part 1021 relative to the bearing layer 101, which is required for the first human eye 2 to capture the picture projected onto the screen 100 by the first projector 200, can be approximately fitted. It can be understood that the inclination angles of the first light reflecting part 1021 at different positions on the screen 100 relative to the bearing layer 101 will be different, and the inclination angles increase or decrease in sequence along the X-axis direction.

Referring to fig. 6, the second projector 210 emits a second light 211 toward the screen 100, and the second light 211 is reflected to the second human eye 3 by the second light reflection portion 1022, where α is a projection angle of the second projector 210, β is an inclination angle of the second light reflection portion 1022 with respect to the carrier layer 101, γ is a reflection angle of the second light 211 projected by the second projector 210 reflected into the second human eye 3, H is a distance from the carrier layer 101 to the second human eye 3, a is a horizontal distance from the second projector 210 to the second human eye 3, and B is a horizontal distance from the second human eye 3 to a reflection point of the second light reflection portion 1022, the inclination angle of the second light reflection portion 1022 with respect to the carrier layer 101 is derived from the angles and the distances, and the mathematical relationship expression is:

β＝90°-α-γ/2

α＝arctg(H/(A+B))*180°/π

γ＝90°-α-arctg(B/H)*180°/π

through the above formula, the inclination angle of the second light reflecting part 1022 relative to the bearing layer 101, which is required for the second human eye 3 to capture the picture projected onto the screen 100 by the second projector 210, can be approximately fitted. It can be understood that the tilt angles of the second light reflecting part 1022 located at different positions on the screen 100 with respect to the carrier layer 101 will be different, and the tilt angles are sequentially increased or decreased along the X-axis direction.

As can be seen from the above explanation, in the X-axis direction, the first light reflection portion 1021 is sequentially set to different inclination angles relative to the carrying layer 101, and the second light reflection portion 1022 is sequentially set to different inclination angles relative to the carrying layer 101, so that two eyes of a person capture different light rays, thereby better presenting a 3D effect and improving 3D display quality.

It is understood that the screen 100 is exposed to the external environment for a long time, a large amount of dust is deposited, and when a foreign object collides with the screen 100, the screen 100 is damaged, which affects the 3D display effect of the screen 100.

In this embodiment, when the screen 100 is accommodated or released, the guide wheels 1121 guide the screen 100 to be accommodated or released, and one side of the screen 100 is completely supported by the guide wheels 1121, so that the screen 100 is not bent in the middle during the process of being accommodated or released, thereby being beneficial to protecting the screen 100 and having a better function of guiding the screen 100 to move.
