Patent ID: 8704241

Claim:
A light-emitting system, comprising: a substrate; and a plurality of bridge-circuit connections electrically connected to each other over the substrate, each bridge-circuit connection comprising: at least four side branches, each side branch comprising: two terminals; and at least one light-emitting micro diode coupled between the two terminals; a central branch comprising at least one light-emitting micro diode; a first intermediate contact between a first side branch and a second side branch of the at least four side branches; and a second intermediate contact between a third side branch and a fourth side branch of the at least four side branches, wherein the central branch is coupled between the first intermediate contact and the second intermediate contact, wherein each of the bridge circuit connections is configured to allow a current flow from the first intermediate contact to the second intermediate contact, to emit light in response to the current flow, and to receive an alternating current input to enable at least a first group of the light-emitting micro diodes to emit light during positive cycles of the alternating current input and at least a second group of the light-emitting micro diodes to emit light during negative cycles of the alternating current input.
