Abstract
A method of manufacturing a light converter with an LED and an amorphous-silicon pin heterojunction diode includes steps of a) preparing an LED structure on one side of a substrate as a light-emitting unit; b) forming a buffer layer on the other side of the substrate; and c) depositing a pin (positive type/intrinsic type/negative type) diode on the buffer layer as a light-absorbing unit this blue/red light converter, and the value of rise time obtained under 1 kf.OMEGA. is 112.5 .mu.sec. The present invention desirably lower the cost, simplify the preparation process, and avoids degrading features of a light converting unit by over-heating during the process of preparing the pin diode.
