Abstract

Official abstract text for this publication.

A method of manufacturing a back light unit of a curved display device according to a technical aspect of the present invention is a method of manufacturing a back light unit applied to a curved display device and comprises the steps of preparing the development shape of a bottom chassis, forming a reinforcing structure on a flat plate of the development shape by roll-forming the flat plate of the development shape, bending an edge of the development shape so that an edge portion of the bottom chassis is formed to stand up on the edge of the bottom chassis, and curving the flat plate on which the reinforcing structure and the edge portion are formed to have a predetermined radius of curvature.

First claim

Opening claim text (preview).

The invention claimed is: 1. A curved back light unit on which a display panel is disposed in a curved shape comprising, a bottom chassis comprising: a back plate that is bent in a predetermined curvature corresponding to a curvature of the display panel; and a reinforcement structure disposed on a rear surface of the back plate; and an edge portion disposed to be bent from an edge of the bottom chassis, wherein the reinforcement structure is disposed along the predetermined curvature of the back plate, and wherein the rear surface of the back plate is a distal surface from a center of the predetermined curvature. 2. The curved back light unit of claim 1 , wherein the bottom chassis is formed by: forming the reinforcement structure on a flat plate of a development shape by roll-forming the flat plate of the development shape; bending an edge of the development shape so that the edge portion of the bottom chassis is formed to stand up; and curving the flat plate on which the reinforcing reinforcement structure and the edge portion are formed to have the predetermined curvature. 3. The curved back light unit of claim 1 , wherein the reinforcement structure is disposed as a pair to be symmetrical up and down with respect to a central portion of the back plate. 4. The curved back light unit of claim 1 , wherein the reinforcement structure is disposed to protrude away from the center of the predetermined curvature, and wherein the edge portion is disposed to be bent toward the center of the predetermined curvature.
