Introduction

Ciaran P. Phelan is an inventor associated with Wallingford, Great Britain, and Apple Inc. His recorded patent work includes an invention for improving luminance uniformity in display devices.

Latest Patents

Phelan is associated with 1 patent, titled “Display Devices with One-Dimensional Pupil Replication.” The patent describes a display with a waveguide, a projector that produces light, and an input coupler that directs the light into the waveguide. To improve luminance uniformity, the display uses structures that replicate the pupil in one dimension, orthogonal to the light’s direction of propagation.

The disclosed approaches include a stacked substrate with pupil-replication and light-redirecting layers, crossed gratings that direct light toward pupil-replication layers, and projector micromirrors that diffract illumination into different modes. These techniques are intended to distribute image light more evenly across the display.
