Miniature Guided Light Array Sequential Scanning Display for Head Mounted Displays.

Abstract

In Phase I, Physical Optics Corporation (POC) demonstrated the feasibility of Guided Light Array Sequential Scanning (GLASS) display technology for use in low-cost, low-power compact night-vision head mounted displays (HMDs). GLASS is based on a unique combination of three technologies: low-power light emitting diode (LED) arrays; a polymer waveguide array substrate; and liquid crystal micro-optics. POC's display surpasses current HMD displays in terms of size, power, resolution, and speed. This is achieved by direct modulation of high-speed LED arrays to generate line images, and by parallel projection of light through a flexible polymer waveguide array sequentially scanned by means of a liquid crystal output coupler array. Using the MHz speed of LEDs and time-multiplexing, the display is capable of high grayscale and dimming range. The production-phase device will be lightweight, rugged, and compact, and will require little power or maintenance. With its high frame rate and high resolution, it will also reduce time-based and spatial image artifacts.
