DETAILED DESCRIPTION

[0039] Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts. However, this disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. [0040] Ranges can be expressed herein as from“about” one particular value, and/or to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent“about,” it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

[0041] Directional terms as used herein - for example up, down, right, left, front, back, top, bottom, vertical, horizontal - are made only with reference to the figures as drawn and are not intended to imply absolute orientation.

[0042] Unless otherwise expressly stated, it is in no way intended that any method set forth herein be construed as requiring that its steps be performed in a specific order, nor that with any apparatus, specific orientations be required. Accordingly, where a method claim does not actually recite an order to be followed by its steps, or that any apparatus claim does not actually recite an order or orientation to individual components, or it is not otherwise specifically stated in the claims or description that the steps are to be limited to a specific order, or that a specific order or orientation to components of an apparatus is not recited, it is in no way intended that an order or orientation be inferred, in any respect. This holds for any possible non-express basis for interpretation, including: matters of logic with respect to arrangement of steps, operational flow, order of components, or orientation of components; plain meaning derived from grammatical organization or punctuation, and; the number or type of embodiments described in the specification.

[0043] As used herein, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. Thus, for example, reference to“a” component includes aspects having two or more such components, unless the context clearly indicates otherwise.

[0044] Referring now to FIGS. 1A-1B, an exemplary connector 100 including alternating electrodes coupled to two adjacent substrates l20a and l20b is schematically depicted. FIG. 1A illustrates a sectional view and FIG. 1B illustrates a top view of connector 100 and substrates l20a and l20b. Connector 100 couples substrates l20a and l20b to each other. In one example, substrates l20a and l20b are sub-displays and connector 100 couples the two sub-displays together to provide a larger display. [0045] First substrate l20a includes a first surface l26a, a second surface l28a opposite to the first surface l26a, and an edge surface l30a extending between the first surface l26a and the second surface l28a. First substrate l20a also includes a plurality of electrodes l22a and a plurality of devices l24a on the second surface l28a of first substrate l20a. Each electrode l22a is electrically coupled to a device l24a. Likewise, second substrate l20b includes a first surface l26b, a second surface l28b opposite to the first surface l26b, and an edge surface l30b extending between the first surface l26b and the second surface l28b. Second substrate l20b also includes a plurality of electrodes l22b and a plurality of devices l24b on the second surface l28b of second substrate l20b. Each electrode l22b is electrically coupled to a device l24b. Electrodes l22a and l22b may be thin film micro electrodes made of copper or another suitable electrically conductive metal (e.g., silver, gold, aluminum, etc). In one example, electrodes l22a and l22b provide signal and/or power connections to devices l24a and l24b, respectively.

[0046] Devices l24a and l24b may be light emitting devices, such as light emitting diodes (LEDs) or microLEDs. As depicted in FIG. 1B, electrodes l22a of first substrate l20a may be offset with respect to electrodes l22b of second substrate l20b. While first substrate l20a and second substrate l20b depicted in FIGS. 1 A-1B each include one column of devices l24a and l24b respectively, in other examples first substrate l20a and second substrate l20b may include any suitable number of devices l24a and l24b, respectively, arranged in any suitable number of rows and columns.

[0047] Connector 100 includes a first portion 102 and a second portion 104. First portion 102 and second portion 104 may include a compliant material. In this example, first portion 102 and second portion 104 are separate components. Second portion 104 is removably coupled to first portion 102 via fasteners l lOa and l lOb. First portion 102 includes a base region 114 including upper surfaces that contact the first surface l26a of first substrate l20a and the first surface l26b of second substrate l20b. First portion 102 also includes a central region 116 extending from the upper surfaces of the base region 114. The central region 116 includes sidewalls that contact the edge surface l30a of first substrate l20a and the edge surface 130b of second substrate l20b.

[0048] Second portion 104 contacts the second surface l28a of first substrate l20a and the second surface l28b of second substrate l20b. Second portion 104 also extends over and contacts the top of the central region 116 of first portion 102. In one example, first substrate l20a includes an array of first light emitting devices l24a having a first pitch between the first light emitting devices, and second substrate l20b includes an array of second light emitting devices l24b having a second pitch between the second light emitting devices. In this example, a width indicated by 105 of second portion 104 of connector 100 is less than the first pitch and the second pitch. The width 105 may be between about l5pm and 300pm in some examples. In other examples, the width 105 may be up to several millimeters depending upon the application.

[0049] A plurality of first electrodes l06a and l06b extend through the first portion 102 including the base region 114 and the central region 116. A plurality of second electrodes l08a and l08b are within second portion 104. In one example, each second electrode l08a and l08b is orthogonal to each first electrode l06a and l06b. Each first electrode l06a electrically contacts a second electrode l08a, and each first electrode l06b electrically contacts a second electrode l08b at an interface 112 between first portion 102 and second portion 104. Each second electrode l08a electrically couples a first electrode l06a to an electrode l22a of first substrate l20a. Each second electrode l08b electrically couples a first electrode l06b to an electrode l22b of second substrate l20b. Each first electrode l06a and l06b and each second electrode l08a and l08b may be made of copper or another suitable electrically conductive metal (e.g., silver, gold, aluminum, etc).

[0050] The device of FIGS. 1A-1B can be assembled by arranging first substrate l20a and second substrate l20b onto first portion 102 of connector 100. Second portion 104 of connector 100 can then be arranged over first substrate l20a, second substrate l20b, and first portion 102 of connector 100. Second portion 104 may then be secured to the first portion 102 with fasteners (e.g., screws, bolts, rods, pins, etc.) l lOa and l lOb. Fasteners l lOa are arranged between second electrodes l08a, and fasteners 110b are arranged between second electrodes l08b.

[0051] Connector 100 and the other connectors described herein below may be fabricated via micro-machining, injection molding, 3D-printing, and/or by other suitable methods. The connectors may be made from a variety of materials to meet electrical, optical, and/or mechanical specifications for a particular application. For example, in a microLED display application, connector 100 may be made from a material that is dark (i.e., light absorbing) and compliant (e.g., silicone) to minimize or effectively eliminate the visibility of the seam between sub-displays. The connectors enable microLED sub-displays to be fabricated in a more traditional manner with top electrodes. As such, through- substrate electrical connections are not needed and thin film electrodes do not need to be coated around an edge of the substrates.

[0052] FIGS. 2A-2B schematically depict an exemplary connector 200 including electrodes coupled to two adjacent substrates l20a and l20b. FIG. 2A illustrates a sectional view and FIG. 2B illustrates a top view of connector 200 and substrates l20a and l20b. Connector 200 couples substrates l20a and l20b to each other. In one example, substrates l20a and l20b are sub-displays and connector 200 couples the two sub-displays together to provide a larger display. First substrate l20a and second substrate l20b were previously described and illustrated with reference to Figure 1A-1B. In this example, as depicted in FIG. 2B, electrodes l22a of first substrate l20a are aligned with electrodes l22b of second substrate l20b.

[0053] Connector 200 includes a first portion 202 and a second portion 204. First portion 202 and second portion 204 may, for example, include a compliant material. In this example, first portion 202 and second portion 204 are separate components. Second portion 204 is removably coupled to first portion 202 via fasteners 210. First portion 202 includes a base region 214 including upper surfaces that contact the first surface l26a of first substrate l20a and the first surface l26b of second substrate l20b. First portion 202 also includes a central region 216 extending from the upper surfaces of the base region 214. The central region 216 includes sidewalls that contact the edge surface l30a of first substrate l20a and the edge surface l30b of second substrate l20b. Second portion 204 contacts the second surface l28a of first substrate l20a and the second surface l28b of second substrate l20b. Second portion 204 also extends over and contacts the top of the central region 216 of first portion 202.

[0054] A plurality of first electrodes 206 extend through the first portion 202 including the base region 214 and the central region 216. A plurality of second electrodes 208 are within second portion 204. In one example, each second electrode 208 is orthogonal to each first electrode 206. Each first electrode 206 electrically contacts a second electrode 208 at an interface 212 between first portion 202 and second portion 204. Each second electrode 208 electrically couples a first electrode 206 to an electrode l22a of first substrate l20a and to an electrode l22b of second substrate l20b. Each first electrode 206 and each second electrode 208 may be made of copper or another suitable electrically conductive metal (e.g., silver, gold, aluminum, etc).

[0055] The device of FIGS. 2A-2B can be assembled by arranging first substrate l20a and second substrate l20b onto first portion 202 of connector 200. Second portion 204 of connector 200 can then be arranged over first substrate l20a, second substrate l20b, and first portion 202 of connector 200. Second portion 204 may then be secured to the first portion 202 with fasteners (e.g., screws, bolts, rods, pins, etc.) 210. Fasteners 210 are arranged between second electrodes 210.

[0056] FIGS. 3A-3B schematically depict another example of a connector 300 including barbed electrodes. FIG. 3A illustrates a sectional view of connector 300 and FIG. 3B illustrates a top view of a second portion 304 of connector 300. Connector 300 is configured to couple substrates (e.g., l20a and l20b) to each other. In one example, the substrates are sub-displays and connector 300 is configured to couple the two sub-displays together to provide a larger display.

[0057] Connector 300 includes a first portion 302 and second portion 304. First portion 302 and second portion 304 may, for example, include a compliant material. In this example, first portion 302 and second portion 304 are separate components. Second portion 304 is coupled to first portion 302 via barbed portions 307a of first electrodes 306a and barbed portions 307b of second electrodes 306b. First portion 302 includes a base region 314 including upper surfaces that are configured to contact the first surface of a first substrate and the first surface of a second substrate. First portion 302 also includes a central region 316 extending from the upper surfaces of the base region 314. The central region 316 includes sidewalls that are configured to contact an edge surface of the first substrate and an edge surface of the second substrate. Second portion 304 is configured to contact the second surface of the first substrate and the second surface of the second substrate. Second portion 304 also extends over and contacts the top of the central region 316 of first portion 302.

[0058] A plurality of first electrodes 306a and 306b extend through the first portion 102 including the base region 314 and the central region 316 and through second portion 304. A plurality of second electrodes 308a and 308b are within second portion 304. In one example, each second electrode 308a and 308b is orthogonal to each first electrode 306a and 306b. Each second electrode 308a includes a through-hole through which a first electrode 306a extends to electrically couple each first electrode 306a to a second electrode 308a. Each second electrode 308b also includes a through-hole through which a first electrode 306b extends to electrically couple each first electrode 306b to a second electrode 308b. Each second electrode 308a is configured to electrically couple a first electrode 306a to an electrode on the second surface of the first substrate. Each second electrode 308b is configured to electrically couple a first electrode 306b to an electrode on the second surface of the second substrate. Each first electrode 306a and 306b and each second electrode 308a and 308b may be made of copper or another suitable electrically conductive metal (e.g., silver, gold, aluminum, etc).

[0059] A device using connector 300 of FIGS. 3A-3B is assembled by arranging a first substrate and a second substrate onto first portion 302 of connector 300.

Accordingly, second portion 304 is secured to first portion 302 by barbed portions 307a and 307b of first electrodes 306a and 306b, respectively.

[0060] FIG. 4 schematically depicts another example of a connector 400 including interlocking portions. Connector 400 couples substrates l20a and l20b to each other. In one example, substrates l20a and l20b are sub-displays and connector 400 couples the two sub- displays together to provide a larger display. First substrate l20a and second substrate l20b were previously described and illustrated with reference to Figure 1 A-1B.

[0061] Connector 400 includes a first portion 402 and a second portion 404. In this example, second portion 404 is shown separated from first portion 402 prior to coupling second portion 404 to first portion 402. First portion 402 and second portion 404 may include a compliant material or another suitable material. First portion 402 includes a base region 414 including upper surfaces that contact the first surface l26a of first substrate l20a and the first surface l26b of second substrate l20b.

The central region 416 includes sidewalls that contact the edge surface l30a of first substrate l20a and the edge surface 130b of second substrate l20b.

[0062] Second portion 404 is removably coupled to first portion 402 via an interlocking feature 410 of first portion 402 and a corresponding interlocking feature 411 of second portion 404. In this example, interlocking feature 410 is in the form of a tab, and interlocking feature 411 is in the form of an opening to engage tab 410 of first portion 402. With second portion 404 coupled to first portion 402, second portion 404 contacts the second surface l28a of first substrate l20a and the second surface l28b of second substrate l20b. Second portion 404 also extends over and contacts the top of the central region 416 of first portion 402.

[0063] A plurality of first electrodes 406 extend through the first portion 402 including the base region 414 and the central region 416. A plurality of second electrodes 408 are within second portion 404. In one example, each second electrode 408 is orthogonal to each first electrode 406 and has an inverted L shape. Each first electrode 406 electrically contacts a second electrode 408 at an interface 412 between first portion 402 and second portion 404 when second portion 404 is coupled to first portion 402. Each second electrode 408 electrically couples a first electrode 406 to an electrode l22a of first substrate l20a. Connector 400 may also include another plurality of first electrodes and another plurality of second electrodes to electrically contact electrodes l22b of second substrate l20b in a similar manner as previously described and illustrated with reference to FIGS. 1A-1B. Each first electrode 406 and each second electrode 408 may be made of copper or another suitable electrically conductive metal (e.g., silver, gold, aluminum, etc).

[0064] The device of FIG. 4 can be assembled by arranging first substrate l20a and second substrate l20b onto first portion 402 of connector 400. Second portion 404 of connector 400 can then be arranged over first substrate l20a, second substrate l20b, and first portion 402 of connector 400 such that opening 411 engages tab 410 to secure second portion 404 to first portion 402.

[0065] FIG. 5 schematically depicts another example of a connector 500 including spring contacts 509. Connector 500 couples a first substrate l20a and a second substrate (not shown) to each other. In one example, the first substrate l20a and the second substrate are sub-displays and connector 500 couples the two sub-displays together to provide a larger display. First substrate l20a was previously described and illustrated with reference to Figure 1A-1B.

Spring contacts 509 of second portion 504 contact the second surface l28a of first substrate l20a and the second surface of the second substrate. Second portion 504 also extends over the central region 516 of first portion 502.

[0067] A plurality of first electrodes 506 extend through the first portion 502 including the base region 514 and the central region 516. A plurality of second electrodes 508 are within second portion 504. A spring contact 509 is electrically coupled to each second electrode 508. In one example, each second electrode 508 is orthogonal to each first electrode 506. Each first electrode 506 is electrically coupled to a second electrode 508. Each second electrode 508 electrically couples a first electrode 506 to an electrode l22a of first substrate l20a via a spring contact 509. Connector 500 may also include another plurality of first electrodes and another plurality of second electrodes to electrically contact electrodes of a second substrate via spring contacts 509. Each first electrode 506, each second electrode 508, and each spring contact 509 may be made of copper or another suitable electrically conductive metal (e.g., silver, gold, aluminum, etc).

[0068] The device of FIG. 5 can be assembled by arranging first substrate l20a onto first portion 502 of connector 500 such that spring contacts 509 contact each electrode l22a of first substrate l20a. Connector 500 applies compression force onto first substrate l20a to hold first substrate l20a in place. A second substrate may be arranged on the other side of connector 500 opposite to first substrate l20a in a similar manner.

Each first electrode 606 includes a protruding portion 607 at the bottom of first portion 602 to electrically couple first portion 602 to support frame 620 by plugging the protruding portions 607 into the support frame. A plurality of second electrodes 608 are within second portion 604. In one example, each second electrode 608 is orthogonal to each first electrode 606. Each first electrode 606 electrically contacts a second electrode 608 at an interface 612 between first portion 602 and second portion 604. Each second electrode 608 electrically couples a first electrode 606 to an electrode l22a of first substrate l20a or to an electrode l22b of second substrate l20b. Each first electrode 606 and each second electrode 608 may be made of copper or another suitable electrically conductive metal (e.g., silver, gold, aluminum, etc).
