The plurality of first light reflectors 1021 and the plurality of second light reflectors 1022 are arranged alternately. The plurality of first light reflection parts 1021 and the plurality of second light reflection parts 1022 are arranged obliquely compared with the carrying layer 101, when the angle between the first light reflection parts 1021 and the preset direction When the angle is an obtuse angle, the angle between the second light reflecting portion 1022 and the preset direction is an acute angle. The first light reflection part 1021 is used to reflect the first light 201 , and the second light reflection part 1022 is used to reflect the second light 211 . It should be noted that the so-called multiple means that the number is greater than or equal to two.

It is understandable that when a person's eyes look at the same object, because there is a certain distance between the two eyes, the scenes seen by the two eyes are not exactly the same. In fact, there are subtle differences in the scenes obtained by the two eyes. When creating a different scene, the two scenes with subtle differences will be merged, and the corresponding three-dimensional scene will be simulated, so that a layered and three-dimensional external environment can be presented.

In this embodiment, the first light reflection part 1021 and the second light reflection part 1022 are arranged obliquely compared with the carrying layer 101, and the degree of inclination here should be based on the incident light of the first light 201 and the second light 211 provided. The direction is determined so that the propagation path of the reflected light of the first light 201 and the second light 211 can reach the designated position.

The inclination angle formed by the second light reflection part 1022 relative to the carrying layer 101 is deduced from the above-mentioned angles and distances, and the mathematical relational 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 formed by the second light reflection part 1022 relative to the carrying layer 101 required for the image projected by the second projector 210 to the screen 100 to be captured by the second human eye 3 can be approximated. It can be understood that the inclination angles of the second light reflection part 1022 at different positions on the screen 100 relative to the carrying layer 101 will be different, and the inclination angles increase or decrease sequentially along the X-axis direction.

From the above description, it can be seen that in the X-axis direction, the first light reflection part 1021 is sequentially arranged at different inclination angles relative to the carrying layer 101, and the second light reflection part 1022 is sequentially arranged at different inclination angles relative to the carrying layer 101, The human eyes can capture different light, so that the 3D effect can be better presented and the 3D display quality can be improved.
