Abstract

Official abstract text for this publication.

A flexible display device includes: a bendable display panel; a protective layer on a surface of the display panel; and an elastic layer on the first surface of the protective layer. The protective layer has a groove in a first surface thereof, and the elastic layer is in the groove in the protective layer.

First claim

Opening claim text (preview).

What is claimed is: 1. A flexible display device comprising: a bendable display panel comprising a substrate, a thin film transistor layer on a first surface of the substrate, and a thin film encapsulation layer covering the thin film transistor layer, the thin film transistor layer being between the substrate and the thin film encapsulation layer; a first elastic layer on the first surface of the substrate and over the thin film encapsulation layer; a second elastic layer on the first elastic layer such that the first elastic layer is between the display panel and the second elastic layer, the second elastic layer having a greater elastic strain energy than the first elastic layer; and a mixed layer between the first and second elastic layers, the mixed layer comprising a material of the first elastic layer and a material of the second elastic layer, wherein both the thin film transistor layer and the thin film encapsulation layer are between the first surface of the substrate and a surface of the first elastic layer facing toward the first surface of the substrate. 2. The flexible display device as claimed in claim 1 , wherein an elastic strain energy of the first elastic layer is about 1 MPa or less, and an elastic strain energy of the second elastic layer is about 10 Mpa or greater. 3. The flexible display device as claimed in claim 1 , wherein the first elastic layer comprises polydimethylsiloxane. 4. The flexible display device as claimed in claim 1 , wherein the second elastic layer comprises thermoplastic polyurethane (TPU) or polyurethane (PU).
