US 12,111,457 B2 · Integrated micro-display module with flex circuitry

Abstract

Aspects of the present disclosure relate generally to night-vision systems and more specifically to an integrated micro-display module with a flex circuit. One example illustrated herein includes a method of upgrading a night-vision system. The method may include attaching a flex circuit to an intensifier module, in which the flex circuit includes one or more light detectors and extending beyond a leading edge of the intensifier module. The method may include inserting the intensifier module into a housing and folding the flex circuit to expose the one or more light detectors. The method may further include optically coupling a display unit to an output side of an intensifier module of the night vision system. The display unit may be configured to display graphical content in a field of view together with night-vision images from an output of the intensifier module of the night-vision system.

A modified night-vision system comprising:

an intensifier module configured to intensify received light input into the intensifier module, the intensifier module having an input side configured to receive photons of the received light and an output side configured to output intensified light resulting from the received light;
a flex circuit attached to the intensifier module, the flex circuit comprising one or more light detectors and extending beyond a leading edge of the intensifier module;
a display unit proximate the output side of the intensifier module, the display unit configured to output graphical content;
a beam combiner optically coupled to the display unit and the output side of the intensifier module and configured to combine the intensified light and graphical content;
an eyepiece optically coupled to the beam combiner, and configured to receive the combined intensified light and graphical content and to provide the combined intensified light and graphical content to a user;
wherein the night-vision system is modified to allow for the display unit and beam combiner to be added to the night-vision system.
