Leaky Mode Light Modification for Optical Displays ID: 2017-031

This invention introduces a novel approach to modifying leaky mode light, enhancing flat screen and near-eye display technologies.

Technology Overview

The technology focuses on the development of structures that can modify leaky mode light to solve the issue of bottom exiting light in optical displays. It employs laser-induced light deflection structures within leaky mode devices to redirect light, enabling direct output below the interaction region. This innovative approach facilitates the construction of tiled displays in two-dimensional arrays, surpassing the previous limitations of one-dimensional arrays due to edge-only light exit.

Key Advantages

• Enables construction of 2D tiled displays, overcoming limitations of 1D arrays
• Reduces scatter from the waveguide, minimizing noise and improving display clarity
• Offers potential for integration with polarizers or low-loss waveguides for further noise reduction
• Applicable to both flat screen and near-eye holographic displays, broadening market applicability

Problems Addressed

• Solves the issue of bottom exiting light in flat screen and near-eye display architectures
• Minimizes scatter and noise in optical displays, enhancing visual quality
• Overcomes the limitations of constructing two-dimensional display arrays

Market Applications

• Near-eye holographic displays for augmented reality (AR) and virtual reality (VR) applications
• Flat screen holographic displays for consumer electronics and professional displays
• Potential partnership opportunities with major technology companies like DAQRI, Microsoft, Magic
• Leap, Google, Intel, and Apple
