Abstract
Top-emitting organic light emitting diode (OLED) structures and fabrication method thereof. A first electrode is formed on a substrate. A dielectric layer including at least one first opening is formed on the first electrode. An organic emission layer is formed on the dielectric layer and fills the first opening. A second electrode including at least one second opening is formed on the organic emission layer. The second opening corresponds to the first opening.
Claims17
A top-emitting organic light emitting diode (OLED) structure, comprising:
- a substrate;
- a first electrode formed on the substrate;
- a dielectric layer comprising at least one first opening formed on the first electrode;
- an organic emission layer formed on the dielectric layer filling in the first opening;
- an electron-transporting layer overlying the organic emission layer;
- and
- a second electrode comprising at least one second opening, wherein the second opening at least exposes a portion of the electron-transporting layer.
A method of forming a top-emitting organic light emitting diode (OLED) structure, comprising:
- forming a first electrode formed on a substrate;
- forming a dielectric layer comprising at least one first opening on the first electrode;
- forming an organic emission layer on the dielectric layer to fill the first opening;
- forming an electron-transporting layer on the organic emission layer;
- and
- forming a second electrode comprising at least one second opening on the electron-transporting layer, wherein the second opening at least exposes a portion of the electron-transporting layer on the organic emission layer.
