Abstract
Official abstract text for this publication.
An organic light-emitting display device includes a substrate, a display unit on the substrate, and a thin film encapsulation unit configured to encapsulate the display unit, and including a corrugated portion including a first layer and a second layer that are sequentially stacked, wherein the first layer includes a material having a lower modulus of elasticity than the second layer, and wherein a corrugated surface is formed at an upper surface of the first layer and a lower surface of the second layer due to a difference in the moduli of elasticity of the first layer and the second layer.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic light-emitting display device comprising: a substrate; a display unit on the substrate; and a thin film encapsulation unit configured to encapsulate the display unit, and comprising a corrugated portion comprising a first layer and a second layer that are sequentially stacked, wherein the first layer has a lower modulus of elasticity than the second layer, wherein a corrugated surface is formed at an upper surface of the first layer and a lower surface of the second layer, wherein the first layer includes a first surface opposite to the corrugated surface, wherein the second layer includes a second surface opposite to the corrugated surface, wherein the first layer and the second layer include identical materials, and wherein light emitted from the display unit passes through both the first surface and the second surface and is transmitted to an outside. 2. The organic light-emitting display device of claim 1 , wherein the first layer comprises an organic layer or an inorganic layer. 3. The organic light-emitting display device of claim 1 , wherein the second layer comprises an organic layer or an inorganic layer. 4. The organic light-emitting display device of claim 1 , wherein the first layer comprises one or more of acrylate, epoxy, silicone, or silicone acrylate. 5. The organic light-emitting display device of claim 1 , wherein the second layer comprises one or more of SiNx, SiOx, SiON, SiCN, TiOx, WOx, SiOxCy, or SiOxCyHz. 6. The organic light-emitting display device of claim 1 , wherein the second layer comprises one or more of acrylate, epoxy, silicone, or silicone acrylate. 7. The organic light-emitting display device of claim 1 , wherein the thin film encapsulation unit further comprises a second corrugated portion. 8. The organic light-emitting display device of claim 1 , wherein the first layer and the second layer each comprise an organic-inorganic hybrid layer. 9. The organic light-emitting display device of claim 8 , wherein the first layer and the second layer each comprise an organic-inorganic composite material comprising one or more of HMDSO, hexamethyldisilazane (HMDSN), tetrameyhyldisiloxane (TMDSO), tetraethyl orthosilicate (TEOS), octamethylcyclotetrasiloxane (OMCTS), or tetraoxymethylcyclotetrasiloxane (TOMCTS). 10. The organic light-emitting display device of claim 1 , wherein the corrugated surface is irregular. 11. The organic light-emitting display device of claim 1 , wherein curves of the corrugated surface have a period of about 2 μm or less and a depth of about 4 μm or less.
