A micro-prism film, with spectral characteristics, is attached on a display panel to show images appearing with + 10° ~ + 50° and -10° ~-50° bright regions and with a + 10° ~-10° 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, ...
