The display screen can be a liquid crystal display screen, and the display screen is composed of a polaroid A, a lower glass layer, an ITO lower electrode, a liquid crystal layer, an ITO upper electrode, a color filter and a polaroid B. The image to be displayed represents an image signal by light, each pixel point in the image to be displayed penetrates through the polarizer B in the form of red light, green light and blue light through the display screen, and enters the barrier grating in the form of polarized light, that is, enters the barrier grating shown in fig. 5 (B).

The display screen comprises a plurality of pixel units, and each pixel unit is respectively arranged corresponding to two adjacent barrier units. When an image to be displayed is presented in a 3D form, a display screen is divided into left-eye pixel units L1, L2, L3 and right-eye pixel units R1, R2, R3, and the left-eye pixel units and the right-eye pixel units are sequentially arranged at intervals, such as L1, R1, L2, R2, L3, R3 shown in fig. 5 (b). When polarized light emitted from the right-eye pixel cells R1, R2, R3 of the display screen passes through the barrier cells of the barrier grating in the right-eye direction, the liquid crystal molecules in the barrier cells are not rotated, and the polarity of the polarized light is rotated by 90 degrees, then is parallel to the transmission axis of the polarizer of the barrier grating, and then passes through the upper polarizer of the barrier grating, thereby entering the right eye of the user. When polarized light emitted by the right-eye pixel units R1, R2, and R3 passes through the barrier unit of the barrier grating in the left-eye direction, the liquid crystal molecules in the barrier unit are rotated by 90 degrees, and the polarity of the polarized light is not rotated, and therefore, the polarized light is perpendicular to the transmission axis of the polarizer of the barrier grating, and then the polarized light is absorbed by the polarizer of the barrier grating, so that the polarized light cannot reach the left eye, so that the polarized light emitted by the right-eye pixel units R1, R2, and R3 only enters the right eye, and the polarized light emitted by the left-eye pixel units L1, L2, and L3 only enters the left eye.
