The multi-view stereoscopic display device 010 provided in the present embodiment is further described below.
The flat light display panel 100 is used for projecting a parallax composite image. The flat light display panel 100 is formed by combining a parallel light source and a liquid crystal display panel. The parallel light source is composed of a point light source and a lens, the point light source is arranged at the focal position of the lens, and light rays emitted by the point light source can form parallel light beams after being refracted by the lens. The liquid crystal display panel is placed in front of the lens, and the parallel light beams formed by refraction of the lens can project the parallax composite image provided by the liquid crystal display panel. The light emitted from each pixel in the parallax composite image that it displays is a parallel beam and propagates in only one spatial direction.

The polymer dispersed liquid crystal panel optical path 020 can be referred to in fig. 2.

When a voltage is applied between the electrodes, the refractive index of the liquid crystal particles substantially matches the refractive index of the polymer, and the polymer dispersed liquid crystal panel 210 is transparent, so that incident light is not scattered.
Only a single one of the polymer dispersed liquid crystal panels is in a scattering state at the same time. When the first polymer dispersed liquid crystal panel 210 is in a scattering state and the second polymer dispersed liquid crystal panel 220 is in a transparent state, the parallax composite image projected by the planar light display panel 100 will be imaged on the first polymer dispersed liquid crystal panel 210. In contrast, when the first polymer dispersed liquid crystal panel 210 is in a transparent state and the second polymer dispersed liquid crystal panel 220 is in a scattering state, the parallax composite image projected by the planar light display panel 100 will be imaged on the position of the second polymer dispersed liquid crystal panel 220.

In the present embodiment, the slit grating as the spectroscopic element 300 has a pitchpIs 2 mmPixel pitch belonging to the same parallax image in the horizontal direction in the parallax composite imagelIs 2.01 mmSpacing of first polymer dispersed liquid crystal panel 210 to light splitting element 300d1 is 5 mmSpacing of the second polymer dispersed liquid crystal panel 220 to the spectroscopic element 300d2 is 6 mm。
Referring to fig. 1, when the parallax composite image is imaged at the position of the first polymer dispersed liquid crystal panel 210, the optimum viewing distanceD1 is 1000mmCan be positioned 1000 at a distance from the spectroscopic element 300mmWhere the viewpoint is formed. The above parameters satisfyD1=pd1/(l-p)。
Referring to fig. 3, when the parallax composite image is imaged at the position of the second polymer dispersed liquid crystal panel 220, the optimum viewing distanceD2 is 1200mmCan be positioned 1200 from the spectroscopic element 300mmWhere the viewpoint is formed. The above parameters satisfyD2=pd2/(l-p)。
Time-division multiplexing, the first polymer dispersed liquid crystal panel 210 and the second polymer dispersed liquid crystalThe scattering and transparent states of the crystal plate 220 are alternately switched, and parallax composite images corresponding to the optimal viewing distances thereof are provided by the flat light display panel 100, respectively. Specifically, at the first moment, the first polymer dispersed liquid crystal 210 panel is in a scattering state, the second polymer dispersed liquid crystal 220 is in a transparent state, and the planar light display panel 100 provides a parallax composite image corresponding to an optimal viewing distance for matching the position of the first polymer dispersed liquid crystal 210 panel; at a second moment, the first polymer dispersed liquid crystal panel 210 is in a transparent state, the second polymer dispersed liquid crystal panel 220 is in a scattering state, and the planar light display panel 100 provides a parallax composite image corresponding to an optimal viewing distance for position matching of the second polymer dispersed liquid crystal panel 220. Then the best viewing distance 1000 can be obtainedmm1200 and method for manufacturing samemmA plurality of viewpoints are formed at the positions. When the eyes are positioned at different viewpoint positions, parallax images corresponding to the eyes can be seen, so that stereoscopic vision is generated.
In the present invention, since the first and second polymer dispersed liquid crystal panels 210 and 220 are continuously alternated between the scattering and transparent states, the viewer can see stereoscopic images at different optimal viewing distances.
