Abstract: A lateral current blocking light-emitting diode and a method for manufacturing the same are disclosed. The light-emitting diode comprises an insulating substrate, a semiconductor epitaxial structure and electrodes of different conductivity types. The semiconductor epitaxial structure has at least one trench and comprises a first conductivity type semiconductor layer deposed on a portion of the insulating substrate, in which a bottom of the trench is beneath the first conductivity type semiconductor layer, an active layer located on a portion of the first conductivity type semiconductor layer, and a second conductivity type semiconductor layer deposed on the active layer.

Abstract: A light emitting diode (LED) having distributed electrodes is disclosed.

Abstract: Disclosed is a charging device for mobile phone wherein the battery can be charged by a secondary coil with current induced from a primary coil in a charging stage. The inventive charging device use magnetic induction, rather than metal contact, to transfer electrical energy to battery, therefore, the poor-contact problem in prior art can be prevented and the alignment tolerance between battery and charging device can be enhanced.
