摘要：
Disclosed is a method of forming a phosphor coating layer on an LED chip using electrophoresis. The method includes separating phosphor particles in a suspension according to a particle size, and coating the phosphor particles on a surface of the LED chip by sequentially depositing the separated phosphor particles on the surface of the LED chip according to the particle size. Also disclosed is an apparatus for forming a phosphor coating layer on an LED chip.
