Integrated micro-display module with flex circuitry
Aspects of the present disclosure relate generally to night-vision systems and more specifically to an integrated 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. The method may include inserting the intensifier module into a housing and folding the flex circuit to expose the one or more light detectors.
1. A method of upgrading a night-vision system, the method comprising
attaching a flex circuit along an exterior side of an intensifier module, the flex circuit comprising one or more light detectors; and
inserting the intensifier module into a housing of the night-vision system in a fashion that allows the light detectors to detect light from light emitters in the night-vision system.
2. The method of claim 1 wherein the flex circuit further comprises:
a first portion having one or more power pads disposed on an outward face of the first portion;
a second portion having the one or more light detectors disposed on an inward face of the second portion; and
one or more bridge portions configured to connect the first portion and the second portion.
3. The method of claim 2 , further comprising folding the flex circuit including:
folding the second portion of the flex circuit onto the first portion of the flex circuit; and
attaching the second portion of the flex circuit to the first portion of the flex circuit using an adhesive material.
4. The method of claim 2 , wherein the second portion has a shape which enables the second portion to be placed in a location relative to the first portion such that the one or more light detectors of the second portion are located above, below, between, outside of, or on top of the one or more power pads of the first portion.
5. The method of claim 1 , wherein attaching the flex circuit further comprises:
attaching the flex circuit extending from a trailing edge of the intensifier module and beyond the leading edge of the intensifier module, wherein the one or more light detectors are located on a portion of the flex circuit beyond the leading edge of the intensifier module.
6. The method of claim 1 , further comprising replacing a flex tail in the night-vision system with a new flex tail including at least one of GPS components, wireless communication components, Wi-Fi components, encrypted Wi-Fi components, an inertial measurement unit (IMU), a compass unit, or an infrared device.
7. The method of claim 1 , further comprising creating additional space inside of the night-vision system by performing at least one of supplying a larger housing, unscrewing of an eyepiece, adding a diopter extension element, adding an eyepiece extension element, physically limiting a number of adjustments that can be made to a diopter, or adding a diopter extension tube.
8. The method of claim 1 wherein light emitters in the night-vision system emit light detectable by the one or more light detectors indicating at least one of low battery conditions or use of night vision IR illumination.
9. The method of claim 1 wherein the one or more light detectors are coupled to one or more additional light emitters to cause the one or more additional light emitters to emit light when light is detected by the one or more light detectors.
10. The method of claim 9 wherein the one or more additional light emitters are disposed on the flex circuit installable on an output side of the intensifier module.
11. 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; and
a flex circuit attached to the intensifier module, the flex circuit comprising one or more light emitters disposed on the output side of the intensifier module.
12. The night-vision system of claim 11 , wherein the flex circuit further comprises one or more light detectors disposed along an exterior side of the intensifier module.
13. The night-vision system of claim 12 , wherein the one or more light detectors are configured to detect one or more indicator lights internal to the night-vision system.
14. The night-vision system of claim 13 , wherein the one or more light detectors are configured cause the one or more light emitters to emit light when the light detectors detect one or more indicator lights internal to the night-vision system.
15. The night-vision system of claim 11 , wherein the flex circuit further comprises:
a first portion having one or more power pads disposed on an outward face of the first portion;
a second portion having one or more light detectors disposed thereon; and
one or more bridge portions configured to connect the first portion and the second portion.
16. The night-vision system of claim 15 , wherein the one or more light detectors are disposed on an inward face of the second portion, and wherein the bridge portion is folded to cause the one or more light detectors to be disposed along an exterior side of the intensifier module.
17. The night-vision system of claim 15 , wherein the first portion or the second portion, or both, include an adhesive material.
18. 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 along an exterior side of an intensifier module, the flex circuit comprising one or more light detectors; and
wherein the intensifier module is inserted into a housing of the night-vision system in a fashion that allows the light detectors to detect light from light emitters in the night-vision system.
19. The night-vision system of claim 18 , wherein the flex circuit further comprises one or more light emitters disposed on the flex circuit on an output side of the intensifier module.
20. The night-vision system of claim 19 wherein the light detectors are configured to cause the light emitters to emit light when light is detected by the light detectors.
