Flexible Display Panel With Localized Thinning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses lack the necessary flexibility to accommodate various shapes and forms, limiting their functionality and usability in modern mobile electronic devices.
Innovation Solution
A display apparatus with high flexibility is designed, featuring a display panel with a through-opening defined by edges of pixel areas and a connection area, where the thickness of the display panel in the connection area is less than in the pixel areas, and a pattern layer including graphene oxide or PTFE is applied to enhance detachment and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display panel has uniform thickness across all areas, then manufacturing is simpler, but flexibility and stretchability are reduced
Solution Approach 1:
The display panel employs different thicknesses in different areas: the first and second pixel areas have a first thickness, while the connection area has a second thickness that is less than the first thickness. This local variation in thickness enables the connection area to be more flexible and stretchable, while the pixel areas maintain sufficient structural integrity for displaying images.
2Strength
If the connection area has the same thickness as pixel areas, then structural integrity is maintained, but flexibility and stretchability are limited
Solution Approach 1:
The connection area is designed with a second thickness that is less than the first thickness of the pixel areas. This localized thinning allows the connection area to stretch and deform more easily when the display apparatus is bent or folded, while the thicker pixel areas maintain sufficient structural integrity to support the display elements and prevent damage during stretching.
3Strength
If the substrate extends into the connection area, then structural support is provided, but detachment difficulty increases
Solution Approach 1:
The substrate is configured to overlap the first pixel area and second pixel area, but does not extend into the connection area. This local absence of substrate in the connection area reduces adhesion strength in that specific region, enabling easier detachment of the display panel from the support substrate during manufacturing, while the substrate still provides sufficient structural support to the pixel areas where display elements are located.

AI summary
A display apparatus includes a display panel in which a through-opening is defined, where the display panel includes a first pixel area in which a first pixel is disposed, a second pixel area in which a second pixel is disposed, and a connection area extending from the first pixel area to the second pixel area, where an edge of the first pixel area, an edge of the connection area, and an edge of the second pixel area define at least a part of the through-opening passing through the display panel, and where a thickness of the display panel in the connection area is less than a thickness of the display panel in the first pixel area.
