ABSTRACT:
A bendable LED planar light source structure, a flexible substrate therefore, and a manufacturing method thereof are provided. The flexible substrate has metal layers on both sides, where the metal layer on one side has a circuit layout, and the metal layer on the other side has a pattern structure or a whole metal coating with reflecting and scattering characteristics. Meanwhile, bonding pads are provided on the same side or opposite side as the metal layer with the circuit layout, and an array of LED dies is bonded with the bonding pads through wire bonding or flip chip bonding, such that the LED dies are conducted with current through the circuit layout on the flexible substrate, so as to form a planar light source.
