Abstract:
1. A bendable light source, comprising: a flexible substrate, having a first metal layer and a second metal layer, wherein the first metal layer has a circuit layout, and the second metal layer is formed on the flexible substrate and has a pattern structure, and besides a plurality of structure regions, a plurality of bonding pads is provided on the structure regions, and electrically connected to the first metal layer; and a plurality of light emitting diode (LED) dies, arranged on the structure regions in an array, and bonded with the corresponding bonding pads, such that the LED dies are conducted with current through the circuit layout of the first metal layer on the flexible substrate, so as to form a planar light source, wherein the second metal layer is a metal coating with high reflectivity and scattering rate and exposes to a lateral light generated by the LED dies, and the structure regions are enclosed by the pattern structure of the second metal layer.
