Abstract: A system for compensating for non-uniformities in an array of solid state devices in a display panel displays images in the panel, and extracts the outputs of a pattern based on structural non-uniformities of the panel, across the panel, for each area of the structural non-uniformities. Then the structural non-uniformities are quantified, based on the values of the extracted outputs, and input signals to the display panel are modified to compensate for the structural non-uniformities. Random non-uniformities are compensated by extracting low-frequency non-uniformities across the panel by applying patterns, and taking images of the pattern. The area and resolution of the image are adjusted to match the panel by creating values for pixels in the display, and then low-frequency non-uniformities across the panel are compensated, based on the created values.

Abstract: This application describes techniques for erasing (e.g., smudging, rendering illegible, etc.) images that are presented on display mediums, such as electronic-paper displays. Electronic-paper displays include a layer of electronic ink comprising charged particles suspended in a fluid. When a voltage differential is created across the reading surface, the charged colored particles may rise to the reading surface, retreat to the opposite surface, or suspend somewhere there between, thereby creating a visible image. In some instances described herein, a common electrode is partitioned into at least two sets of elements interleaved with one another. To erase an image, a voltage differential may be driven between these two sets of elements, creating an in-plane electrical field that erases the image.

The WHUDs described herein each include a scanning laser projector (“SLP”), a holographic combiner, and an optical replicator positioned in the optical path therebetween. For each light signal generated by the SLP, the optical replicator receives the light signal and redirects each one of N>1 instances of the light signal towards the holographic combiner effectively from a respective one of N spatially-separated virtual positions for the SLP. The holographic combiner converges each one of the N instances of the light signal to a respective one of N spatially-separated exit pupils at the eye of the user. In this way, multiple instances of the exit pupil are distributed over the area of the eye and the eyebox of the WHUD is expanded.

A WHUD includes a scanning laser projector (“SLP”), a holographic combiner, and an optical splitter positioned in the optical path therebetween.
