Abstract:
1. 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 and disposed in the non-pixel region, 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; a scan driver formed over the non-pixel region and comprising a semiconductive integrated circuit portion and a non-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 overlap with the semiconductive integrated circuit portion and overlaps with the non-semiconductive integrated circuit portion when viewed in the second direction from the first or second substrate; and a signal line portion, wherein the signal line portion comprises a plurality of conductive lines interconnecting the scan driver and the array, wherein the signal line portion is not formed over the pixel region, and wherein the first elongated segment overlaps with the signal line portion when viewed in the second direction from the first or second substrate, wherein the semiconductive integrated circuit portion has a width defined in a third direction perpendicular to the first and second directions, and wherein the semiconductive integrated circuit portion and the first elongated segment have substantially no gap in the third direction when viewed in the second direction from the first or second substrate.
