MULTI-COLOR LIGHT EMITTING DIODE AND METHOD FOR MAKING SAME

摘要

A color light-emitting diode using a blue light component to produce red light and green light is disclosed. A blue-light emitting material provided between a cathode layer (44) and an anode layer (50) for emitting the blue light component. A light re-emitting layer (54) has a first material in a first diode section (541) arranged to produce a red light component in response to the blue light component, and a second material in a second diode section (542) arranged to produce a green light component in response to the blue light component. A transparent material in a third diode section (543) allows part of the blue light component to transmit through. The anode layer (50) is partitioned into three electrode portions separately located in the three diode sections, so that the red, green and blue light components in the diode sections can be separately controlled.
