Abstract
Flexible, fabric-encapsulated light arrays particularly suitable for use in clothing are disclosed. The light arrays are light-emitting diode (LED) arrays disposed on flexible printed circuit boards (PCBs). The flexible PCBs include substantially sinusoidal metal contact traces, along which the LEDs are attached at an angle preselected to minimize stresses in the expected directions of bending. The PCBs may also include enlarged metal contact pads and a coverlay arrangement to prevent delamination. The light arrays are contained within pockets that may be made of conductive fabric in order to form a Faraday cage. Systems and methods are also disclosed that use local and wide-area controllers to send words, images, and video to the light arrays substantially in real time.
