Abstract

Waveguide displays provide a transparent optical solution to deliver an augmented digital layer to the physical world. We will present reflective waveguide technology and specifically our progress with a novel 2D pupil expansion waveguide architecture. This 2nd generation 2D reflective waveguide architecture provides further improvements in image quality together with a very small waveguide entrance pupil. This small waveguide entrance pupil allows for very compact projector modules that can be easily integrated into the consumer glasses frame. It also enables for direct bonding of optical elements on the waveguide’s surface providing seamless integration of an encapsulation layer or Rx solution directly on the waveguide. The projector together with the waveguide assembly provide a crisp, high-resolution image and significant advantages in power efficiency, color uniformity, light leakage, and glare free view of the physical world.
