Flexible Micro-Electronics Circuits with Crack Mitigation

摘要

An electronic circuit device that includes a plurality of electrical circuits disposed on a support substrate, such as an electronic display device, includes one or more primary electrodes that extend along a trace on the support substrate, wherein the primary electrodes form one or more primary electrical pathways of or to one or more of the electrical circuits. One or more secondary electrodes are disposed along and in electrical contact with the primary electrodes. The secondary electrodes extend along the trace substantially parallel with the primary electrodes and form secondary electrical pathways adjacent the primary electrical pathways. The secondary electrodes are formed of a secondary conductor that is electrically conductive and has a higher strain limit than the primary electrodes. The secondary electrodes are able to handle a higher amount of strain than the primary electrode without breaking the secondary electrical pathway and thereby are arranged to complete the electrical circuits when a gap in a primary electrode interrupts the electrical circuit through the primary electrode.

1. An electronic circuit device, comprising:
a plurality of electrical circuits disposed on a support substrate; at least one primary electrode extending along a trace on the support substrate, wherein the primary electrode forms a primary electrical pathway of at least one of the electrical circuits; and a secondary electrode disposed along and in electrical contact with the primary electrode, wherein the secondary electrode extends along the trace substantially parallel with the primary electrode and forms a secondary electrical pathway adjacent the primary electrical pathway; wherein the secondary electrode is formed of a secondary conductor that is electrically conductive and has a higher strain limit than the primary electrode, and wherein the secondary electrode handles a higher amount of strain than the primary electrode without breaking the secondary electrical pathway and thereby completes the electrical circuit when a gap in the primary electrode interrupts the electrical circuit through the primary electrode.
