LED chips have two basic structures, transverse structure and vertical structure.

The two electrodes of the transverse structure LED chip are in the same side of the LED chip, and the current flows in an equal distance between the n-and p-type limits.

Vertical structure of LED chips, two electrodes on both sides of the LED epitaxial layer respectively, because of the graphical electrode and all p - type restrictions as a second electrode layer, make almost all current through the LED epitaxial layer, vertical rarely transverse flow of current, can improve the current distribution of the flat structure, improve the luminous efficiency, also can solve the problem of p of shading, improve the LED light emitting area.
