Abstract

Time Multiplexed Optical Shutter (TMOS) is a new approach to flat panel light valve display technology that addresses display requirements in avionics applications, particularly head-down cockpit deployments. TMOS modulates the local transmission of light from a waveguide coextensive with the screen. The architecture requires fewer, larger on-screen features (e.g., TFTs) than prevailing technologies because it exploits field sequential color techniques. Methods to mitigate color break up are presented. TMOS exhibits lower power consumption, lower weight, a simplified architecture, and better visual quality than incumbent display technologies while overcoming their limitations (e.g., poor light efficiency, and size/weight constraints due to yield and backlighting). TMOS should meet avionics needs without additional ruggedization enhancements, offers high immunity to EMP, and can be constructed from transparent materials (allowing z-axis redundancy to improve cockpit ergonomics). Respecting the avionics market, TMOS has advantages over incumbent display technologies, including lower sensitivity to temperature variation, greater immunity to vibration, higher system efficacy (power in to light out), and larger dimming ratios. The status of TMOS development and its fit within avionics applications is addressed.
