Abstract
Disclosed is an organic light emitting display device including a first substrate defining a pixel region and a non-pixel region. An organic light emitting element comprising a first electrode, an organic thin film layer and a second electrode are formed in the pixel region. A scan driver is formed in the non-pixel region. A second substrate is sealed spaced apart from the pixel region and the non-pixel region of the first substrate. A frit is formed along an edge of a non-pixel region of the second substrate, wherein the frit is formed so that it can be overlapped with a region excluding an active area of the scan driver formed in the non-pixel region.
Claims18
An organic light emitting device comprising:
- a first substrate defining a pixel region and a non-pixel region;
- an array of organic light emitting pixels formed over the pixel region of the first substrate;
- a second substrate placed over the first substrate, the array being interposed between the first and second substrates;
- a frit seal comprising a plurality of elongated segments interposed between the first and second substrates, the plurality of elongated segments in combination surrounding the array such that the array is encapsulated by the first substrate, the second substrate and the frit seal, the plurality of elongated segments comprising a first elongated segment elongated generally in a first direction;
- and
- a scan driver formed over the non-pixel region and comprising a semiconductive integrated circuit portion, wherein the semiconductive integrated circuit portion and the first elongated segment extend generally parallel to each other without any one of the plurality of elongated segments interposed therebetween when viewed in a second direction from the first or second substrate, wherein the second direction defines the shortest distance between the first and second substrates, and wherein the first elongated segment does not substantially overlap with the semiconductive integrated circuit portion when viewed in the second direction from the first or second substrate.
A method of making an organic light emitting device, the method comprising:
- providing a first substrate defining a pixel region and a non-pixel region;
- forming an array of organic light emitting pixels over the pixel region of the first substrate;
- forming a scan driver over the non-pixel region of the first substrate;
- arranging a second substrate over the first substrate such that the array being interposed between the first and second substrates;
- interposing a frit comprising a plurality of elongated segments between the first substrate and second substrate, the plurality of elongated segments in combination surrounding the array, and the plurality of elongated segments comprising a first elongated segment elongated generally in a first direction;
- and
- wherein the scan driver comprises a semiconductive integrated circuit portion, wherein the semiconductive integrated circuit portion and the first elongated segment extend generally parallel to each other without any one of the plurality of elongated segments interposed therebetween when viewed in a second direction from the first or second substrate, wherein the second direction defines the shortest distance between the first and second substrates, and wherein the first elongated segment does not substantially overlap with the semiconductive integrated circuit portion when viewed in the second direction from the first or second substrate.
