A micro-prism film, with spectral characteristics, is attached on a display panel to show images appearing with + 10 degrees similar to + 50 degrees and -10 degrees similar to-50 degrees bright regions and with a + 10 degrees similar to-10 degrees dark region. When both eyes separately receive the bright region and the dark region of an image, interocular delay would appear to generate a stereo perception. With the optical simulation software, LightTools 7.3.0, to simulate the brightness change, the light with lower brightness appears on the 0 degrees region and the light with the highest brightness appears on the +/- 10 degrees region. The optimal viewing distance of 25cm could accurately deliver the image with shading parallax to both eyes. The actual measurement of brightness presents the shading distribution, achieving the condition of binocular retinal illumination, and the angle of visibility appears on the +/- 50 degrees region, causing interocular delay so that the viewer generates the stereo perception.

The twisted nematic liquid crystal to replace the conventional grating on an autostereoscopic panel. This study analyzes the crosstalk effect with different widths of slit pitch of grating at different viewing distances from 30cm to 150cm. From the simulation results, the crosstalk reduces down to 3.5% at each position.
