Methods for system layout optimization for retro-reflective based display systems

Abstract

The present disclosure provides a display system that may comprise a retro-reflective screen configured to reflect incident light along a direction that is opposite to the direction of propagation ofthe incident light, and a projector that may project light characterizing an image or video to the retro-reflective screen. An array of optical elements or an individual optical element may be positioned between the retro-reflective screen and the projector. The array of optical elements or individual optical element may direct the light from the projector to the retro-reflective screen in a manner such that the image or video is viewable by a user at an observation angle of at least about 2 degrees.

Description

[0001] cross reference [0002] This application claims priority to US Provisional Patent Application Serial No. 62 / 255,218, entitled "Methods for System Layout Optimization for Retro-Reflective Based Display Systems," filed November 13, 2015, which is incorporated herein by reference in its entirety. Background technique [0003] Current state-of-the-art display systems generally include flat panel displays or projector-based displays. Flat panel displays are generally based on liquid crystal display (LCD) pixels with light emitting diode (LED) backlights or plasma based screens. In general, screen sizes significantly larger than 80 inches in diagonal size are difficult to obtain due to various considerations. For flat panel displays, the non-linear increase in cost as screen size increases and high power consumption can limit screen sizes to below 80 inches at typical consumer price points. For projection-based displays, reduced screen brightness and increased power consu...

AI Technical Summary

Problems solved by technology

In general, screen sizes significantly larger than 80 inches in diagonal size are difficult to achieve due to various considerations

For flat-panel displays, the non-linear increase in cost as screen size increases and high power consumption can limit screen sizes to less than 80 inches at typical consumer price points

For projection-based displays, reduced screen brightness and increased power consumption, projector size, and projector noise can be significant limitations if the display size increases beyond 80 inches

Another limitation of current state-of-the-art displays is that no low-cost solution exists to enable multiple viewers to view personalized content simultaneously on the same screen area

Furthermore, no simple solution for naked-eye three-dimensional (3D) immersive viewing currently exists for both types of displays
