Abstract
Official abstract text for this publication.
An organic light emitting diode display includes a flexible substrate, a driving layer positioned on the flexible substrate and including a thin film transistor, an element layer positioned on the driving layer and including an organic light emitting diode that is connected to the thin film transistor, a thin film encapsulation layer covering the element layer and encapsulating the element layer and the flexible substrate, and a compensation layer positioned between the element layer and the flexible substrate.
First claim
Opening claim text (preview).
What is claimed is: 1 . An organic light emitting diode display, comprising: a flexible substrate; a driving layer positioned on the flexible substrate and including a thin film transistor; an element layer positioned on the driving layer and including an organic light emitting diode that is connected to the thin film transistor; a thin film encapsulation layer covering the element layer and encapsulating the element layer and the flexible substrate; and a compensation layer positioned between the element layer and the flexible substrate. 2 . The organic light emitting diode display as claimed in claim 1 , wherein the compensation layer includes a viscoelastic material. 3 . The organic light emitting diode display as claimed in claim 2 , wherein, when a bending moment is generated in the organic light emitting diode display, a first neutral plane is formed between the thin film encapsulation layer and the compensation layer, and a second neutral plane is formed between the compensation layer and the flexible substrate. 4 . The organic light emitting diode display as claimed in claim 1 , wherein the compensation layer is positioned between the element layer and the driving layer and contacts the element layer and the driving layer, respectively. 5 . The organic light emitting diode display as claimed in claim 1 , wherein the compensation layer is positioned between the driving layer and the flexible substrate and contacts the driving layer and the flexible substrate, respectively. 6 . The organic light emitting diode display as claimed in claim 1 , wherein, when a bending moment is generated in the organic light emitting diode display, an interface between the element layer and the thin film encapsulation layer is formed as a neutral plane. 7 . The organic light emitting diode display as claimed in claim 1 , wherein the flexible substrate includes a substrate main body part including a polymer and a buffer layer positioned on the substrate main body part. 8 . The organic light emitting diode display as claimed in claim 1 , wherein: an edge of the thin film encapsulation layer contacts the flexible substrate, and the edge of the thin film encapsulation layer and the flexible substrate are bonded to each other by laser bonding. 9 . An organic light emitting diode display, comprising: a flexible substrate; a driving layer positioned on the flexible substrate and including a thin film transistor; an element layer positioned on the driving layer and including an organic light emitting diode that is connected to the thin film transistor; and a thin film encapsulation layer covering the element layer and encapsulating the element layer along with the flexible substrate; wherein, when a bending moment is generated in the organic light emitting diode display, an interface between the element layer and the thin film encapsulation layer is formed as a neutral plane. 10 . The organic light emitting diode display as claimed in claim 9 , further comprising a compensation layer positioned between the element layer and the flexible substrate. 11 . The organic light emitting diode display as claimed in claim 10 , wherein the compensation layer includes a viscoelastic material.
