preparation Embodiment 1

[0117] A colorless polyimide (CPI) film (TS-50-P, Kolon) having a thickness of 50 μm and a thermoplastic polyurethane film (TPU) having a thickness of 150 μm (modulus of elasticity: approx. 15 MPa) Assembly: Optically Clear Adhesive (OCA) (8147, 3M) having a thickness of 50 μm (elastic modulus: 0.1 MPa or less) was inserted. Subsequently, the composition for the protective layer (including 15% by weight of (3-mercaptopropyl)trimethoxysilane (MPTMS) modified silica, inorganic binder (NCH2020, Miwon Specialty Chemical Co. , Ltd.), and an organic-inorganic hybrid composition of a mixture of a urethane acrylate organic binder (MU9800, Miwon Specialty Chemical Co., Ltd.)) coated on the colorless polyimide film on the opposite surface and dry and then at 33 milliwatts / square centimeter (mW / cm 2 ) light intensity for 30 seconds to provide a protective layer (HC) having a thickness of 10 μm and to provide a window.

[0118]In the window, TPU (150 μm) / OCA (50 μm) / CPI (50 μm) / HC (10 μ...

preparation Embodiment 2

[0120] A window was obtained according to the same procedure as in Preparation Example 1 except that an optically clear adhesive having a thickness of 25 μm was used instead of an optically clear adhesive having a thickness of 50 μm.

[0121] In the window, TPU (150 μm) / OCA (25 μm) / CPI (50 μm) / HC (10 μm) were sequentially stacked from the lower part.

Embodiment 1

[0136] A display panel (Samsung Electronics Co., Ltd., S6 Galaxy panel) and the window obtained in Preparation Example 1 were assembled using an optically clear adhesive (8147, 3M) (elastic modulus: less than or equal to 0.1 MPa) to provide a sample .

Abstract

The present invention discloses a window for a display device and the display device. The window for the display device includes a polymer substrate, a first buffer layer under the polymer substrate and having an elastic modulus of about 7 megapascals to about 30 megapsacals, a first transparent adhesion layer between the polymer substrate and the first buffer layer and a protective layer on the polymer substrate, and the display device includes the window used for the display device.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to Korean Patent Application No. 10-2016-0124090 filed with the Korean Intellectual Property Office on Sep. 27, 2016, and all rights arising therefrom, the contents of which are incorporated herein by reference in their entirety . technical field [0003] A window (window) for a display device and a display device are disclosed. Background technique [0004] As portable electronic devices such as smartphones or tablet personal computers are becoming more diverse, there is also a need for a display device that has bendable or foldable flexibility and is thin and lightweight. [0005] Generally, a display device installed in a portable electronic device may include rigid glass for protecting the display module. However, glass lacks the desired amount of flexibility to be effectively used in flexible display devices. Polymer films have been investigated as replacements for g...
