Curved Display Panel Assembly for Corner Buckling Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with curved surfaces are prone to buckling or wrinkling during bending, leading to deteriorated display quality.
Innovation Solution
A panel assembly comprising a metal plate with a bent portion and a display panel, adhered by a resin or pressure sensitive adhesive, is fixed and pressed from bottom to top, inducing only tensile force to prevent compressive deformation at the corner portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the corner portion of the display panel is bent to create a curved surface, then the display panel achieves three-dimensional curved shape and design flexibility, but buckling or wrinkling occurs leading to deteriorated display quality
Solution Approach 1:
The metal plate is pre-formed with a bent portion that corresponds to the bent portion of the display panel before the bending process. This preliminary shaping of the support structure ensures that during subsequent bending operations, the display panel follows the pre-established curvature path, preventing buckling and wrinkling at corner portions while achieving the desired three-dimensional curved shape.
Solution Approach 2:
The patent introduces a metal plate as an intermediary support structure between the bending mechanism and the display panel. This metal plate acts as a mediator that transfers and controls the bending force, providing a stable curved surface for the display panel to conform to, thereby preventing direct compression and deformation issues that would otherwise occur during bending.
2Shape
If compression force is applied to bend the corner portion, then the display panel achieves curved shape, but compressive deformation causes buckling and wrinkling defects
Solution Approach 1:
Instead of applying compression force directly to bend the display panel corner portion, the patent inverts the approach by using a pre-formed metal plate with the desired curvature. The metal plate is bent in advance to create the target shape, and then the display panel is conformally attached to this pre-shaped support, transforming the bending process from a compressive operation into a formative operation that avoids compression-induced defects.
Solution Approach 2:
The metal plate is pre-formed with the exact bent shape required before the display panel is attached. This preliminary shaping establishes the final curved geometry in advance, allowing the display panel to simply conform to the pre-established form without undergoing compressive deformation that would cause buckling or wrinkling during the shaping process.

AI summary
A panel assembly includes a metal plate and a display panel disposed on the metal plate and having a bent portion at at least one corner portion. By pressing the panel assembly from bottom to top, defects such as buckling and wrinkling can be prevented from occurring at corner portion.
