Abstract
A series of light-emitting diodes (LEDs) flexibly interconnected to form an string is useful for forming displays with various patterns of LEDs. In the present invention, such a string of LEDs can be readily mass-produced by attaching the LEDs to a foldable flexible substrate. The substrate is then folded and inserted into a flexible transparent holder. The spaces between the holder and the substrate are filled with resin. In another embodiment, the substrate, with the LEDs attached, are held by fork-shaped tools in the space of a mold and the mold injected with molten resin. Before the resin cools completely, the tools are withdrawn and the resin permitted to fill in any voids left behind.
