Patent ID: 6989280

Claim:
A method of manufacturing an organic light-emitting diode (OLED) device for reducing ambient-light reflection thereof, the method comprises the following steps of: providing a substrate; depositing a metal reflective layer on said substrate; depositing a transparent anode on said metal reflective layer; depositing an organic layer on said transparent anode; depositing a translucent electron-injecting cathode on said organic layer; depositing a buffer layer on said translucent electron-injecting cathode; and depositing a transparent electrode on said buffer layer; wherein the ambient-light illuminates said translucent electron-injecting cathode and said metal reflective layer to separately have a first reflected light and a second reflected light, wherein by adjusting the thickness of one or both of said organic layer and said transparent anode, said first reflected light and said second reflected light have a phase difference about 180 degrees and result in destructive interference so as to degrade the effect of reflected light caused by ambient-light and improve the visually perceived contrast of the emitted light.
