ABSTRACT:
The leads of a light emitting diode are made coaxial. The inner lead protrudes lower than the outer lead. The package is inserted into a spongy display panel for power supply. The display panel has three layers: a lower conducting layer for contacting said inner lead and a top conducting layer for contacting said outer layer, and an insulating layer between the top and the bottom layer. For LED with a bottom electrode and a top electrode, the LED can be mounted on the planar tops of the inner lead and the top electrode wire bonded to the outer lead, or the LED can be mounted on the side surface of the inner lead and the top electrode wire bonded to the outer lead. For LED with two bottom electrode, the LED electrodes can straddle over the planar tops of the inner lead and the outer lead, or the LED electrodes can straddle over the telescopic side surfaces of the two leads.
