Abstract
A matrix structure-based light-emitting diode array includes a plurality of input resistances connected in parallel to one terminal of a current source, and a plurality of output resistances connected in parallel to another terminal of a current source. Light-emitting diodes are then used to connect each of the input resistances to each of the output resistances. Arranged as such, no two light-emitting diodes is connected in parallel and, as such, the failure of any one light-emitting diode does not extinguish any of the other light-emitting diodes.
