Abstract

The present invention relates to flexible display panels and methods of bending them. A flexible display panel includes a display area displaying images and a non-display area disposed outside the display area. The non-display area includes a first part and a second part. The first portion extends from the display area and includes a support layer disposed on the flexible substrate. The second portion extends from the first portion and is curved from the plane of the first portion. The nature of the material of the support layer in the first part is different from the nature of the material of the support layer in the second part.

Description

technical field [0001] Example embodiments relate to display technologies, and more particularly, to flexible display panels and methods of bending the same. Background technique [0002] Display devices have become the hallmark of the modern information consumption society. Whether in the form of a cellular phone, consumer appliance, portable computer, television, etc., aesthetic and ergonomic appeal are as much a design consideration as display quality and overall performance. Therefore, more attention is directed to developing display devices with minimal to bezel-less configurations. A flexible display panel that can be permanently deformed (eg, bent) in areas peripheral to the display area thereby enabling a reduction in the planar surface area of ​​these peripheral areas gains traction at least because such a configuration also keeps peripheral circuitry close to the display area. It should be noted, however, that as the bend radius of the peripheral region decreases...
