Abstract
This invention provides a top-emitting OLED display device that includes a substrate; an array of OLED elements disposed on one side of the substrate; and a desiccant material provided in a patterned arrangement over the array of OLED elements on the same side of the substrate such that the desiccant material does not interfere with the light emitted by the OLED elements.

A top-emitting OLED display device comprising:
- a) a substrate;
- b) an array of OLED elements disposed over one side of the substrate;
- and
- c) desiccant material provided in a patterned arrangement over the array of OLED elements on the same side of the substrate such that the desiccant material does not interfere with the light emitted by the OLED elements.
A top-emitting OLED display device comprising:
- a) a substrate;
- b) an array of OLED elements disposed over one side of the substrate wherein the light-emitting area of each OLED element defines a light-emitting pixel area;
- and
- c) desiccant material provided in a patterned arrangement over the array of OLED elements on the same side of the substrate, such that the desiccant material is provided between the light-emitting pixel areas.
A top-emitting OLED display device comprising:
- a) a substrate;
- b) an array of thin film transistors provided over the substrate;
- c) a patterned first insulating layer provided over the array of thin film transistors;
- d) an array of first electrodes in electrical contact with the thin film transistors;
- e) a second insulating layer provided over the array of first electrodes, wherein the second insulating layer is patterned to expose at least a portion of the first electrodes, the area of which defines the light-emitting pixel area;
- f) an array of organic electro-luminescent elements deposited over the array of first electrodes;
- g) a transparent, common second electrode provided over the array of organic electro-luminescent elements;
- and
- h) desiccant material provided in a patterned arrangement over the second electrode, such that the desiccant material is provided between the light-emitting pixel areas.

- and
- c) forming a patterned arrangement of desiccant material on the same side of the substrate and arranged between the light-emitting pixel areas such that the desiccant material does not interfere with the light emitted by the OLED elements.
A top-emitting OLED display device, comprising:
- a) substrate;
- b) an array of first electrodes provided over the substrate;
- c) an array of organic electro-luminescent elements deposited on the array of first electrodes such that there are gaps formed between the organic electro-luminescent elements;
- d) desiccant material provided within the gaps formed between the organic electro-luminescent elements;
- and
- e) a transparent, common second electrode provided over the array of electro-luminescent elements and desiccant material.
