An Autosteresoscopic 3D Display System Based on Prism Patterned Projection Screen

Arrays of Lucius microprisms for directional allocation of light and autostereoscopic three-dimensional displays

“…Although autostereoscopy with a prism-patterned screen that is applicable for projection-type display only has recently been reported 32 , the schemes that flat-panel industry currently relies upon for autostereoscopic 3D display [27][28][29][30][31] are typically variations of parallax barriers 33 and lenticular lenses 34 for which the origins date back to the 1900s. In the Lucius prism array presented here, the incident light is guided through the prism with directionality so that a different image is viewed at a different position without periodic change of images depending on the viewing angle 31 , which is typically encountered in the two traditional cases (Supplementary Movie 5, based on the scheme of parallax barriers).…”

Demonstration of an Autostereoscopic Three-Dimensional Light-Emitting Diode Display Using Diffractive Optical Elements Sheet

“…To make a trade-off between fabrication difficulty and diffraction efficiency, 4-level is chosen in our work to quantize the phase function of the C-DOEs [20]. Spherical approximation is used to obtain the phase function in (5). To achieve better display effect (minimized 3D crosstalk and 3D luminance difference), optimized value of conic constant of aspherical approximation can be calculated using the method presented in [23].…”

“…Large size 3D displays offer better visual experience. Owing to the limitations of the low illuminance and the long projection distance, the commonly used projection technique [1][2][3][4][5][6][7] for large size 3D display is inadequate in most applications. Light-emitting Diode (LED) display has the advantages of high brilliance and convenient assembly, and is nonsubstitutable especially in out-doors and stage applications.…”

The design of an achromatic two dimensional deflection prism

“…Among which, the combination of a typical 2D display and a specific structure based on parallax barrier or lenticular lens arrays are potential due to the low cost and easy fabrication. Similar solutions are also workable on the case of 3D projection system [1][2][3]. For implementing the autostereoscopic or multi-view projection image, a rear projection screen composed of suitable designed prism array conveys 3D information with two separated images for left and right eye perceptions, or the different images presented for various viewers.…”
