Abstract
An organic light emitting display device and a manufacturing method of forming an inorganic layer formed on the top of the sealing film with nitride are disclosed. In one embodiment, the organic light emitting display device includes: i) a substrate on which at least one organic light emitting diode is formed and ii) a sealing film stacked with at least one organic film and inorganic film and sealing the organic light emitting diode, wherein the top of the sealing film is formed of an inorganic film formed of nitride.
Claims20
An organic light emitting display device comprising:
- a substrate;
- at least one organic light emitting diode formed on the substrate;
- and
- a sealing film configured to prevent at least one of moisture and oxygen from contacting the at least one organic light emitting diode, wherein the sealing film comprises at least one organic layer and at least one inorganic layer,
- wherein the sealing film comprises a top layer, which is the farthest from the substrate among the layers of the sealing film, and wherein the top layer comprises a nitride material.
A method of manufacturing an organic light emitting display device comprising:
- providing a substrate and at least one organic light emitting diode formed on the substrate;
- and
- forming a film over the at least one organic light emitting diode, wherein the film comprises at least one organic layer and at least one inorganic layer, wherein the film comprises a top layer which is the farthest from the substrate among the layers of the film, and wherein the top layer comprises a nitride material.
An organic light emitting display device comprising:
- a substrate;
- an array of organic light emitting diodes formed on the substrate, wherein the array comprises a top surface and side surfaces;
- wherein the top surface faces away from the substrate, and wherein the side surfaces interconnect the top surface and the substrate;
- and
- a film, formed over the array, configured to prevent at least one of moisture and oxygen from contacting the array, wherein the film comprises at least one layer, which comprises a nitride material, and wherein the at least one layer comprising the nitride material has a Pencil Hardness value of HB or harder.
