Evans & Sutherland Advanced Displays

Evans & Sutherland's advanced display technology harnesses cutting-edge diffraction optics combined with simple projection optics and standard CMOS silicon. This innovative approach offers high yields at lower costs and operates incredibly fast—4 to 5 orders of magnitude quicker than traditional LCD or DMD technologies. The technology allows continuous intensity variation without discrete modulation. With a focus on high-resolution applications, it aims to replace outdated CRT projectors and enhance large venue entertainment, vehicle displays, and home entertainment systems, providing a standard of quality that's "better than film."

  1. Evans & SutherlandAdvanced Displays

  2. Technology

  3. Description of technology • Diffraction optics • Simple projection optics • Simple, standard CMOS silicon • High yields, low cost • Very, very fast • 4-5 orders of magnitude faster than LCD or DMD • Continuous intensity variation! • Not discrete • Not pulse width modulated

  4. orders -2 -1 0 +1 +2 maxima: sin q = n(l/p) shorter wavelength => shallow angle wider pitch => shallow angle

  5. GLV Pixel Structure Micro-ElectroMechanical (MEMS) Technology “Square-well” diffraction grating Ribbon deflection

  6. How the GLV Works • IncidentLight • IncidentLight ReflectedLight • DiffractedLight • DiffractedLight

  7. Single pixel side view power: I1st = Imax sin2(2pd/l) d = 0 => no power d = l/4 => max power

  8. Business History

  9. Milestones • 1996 - E&S begins display technology search • 1997 - Investment of $3.5MM in Silicon Light Machines (SLM) • 1998 - E&S staffs up to support maturing technology • 1999 - Prototype projector delivered

  10. Future

  11. Future • Eye limited resolutions for pilot training • Replace CRT projectors in high resolution applications • Display systems at new price/performance points • Create large venue entertainment products • Support emerging applications • “Better than film” cinema projectors • Vehicle displays • Home entertainment
