Curved Display Support Member Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals with curved display surfaces are vulnerable to external impacts, and the non-display areas at these curved regions are both mechanically weak and visible, posing issues for impact resistance and aesthetics.
Innovation Solution
Incorporating a support member structure along the bent areas of the display panel and window member, which enhances mechanical strength and positions non-display areas away from the visible window area, thereby reducing visibility and improving impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a curved display surface is used to achieve diversified design, then the aesthetic appeal and design versatility are improved, but the impact resistance and mechanical strength at bent areas deteriorate
Solution Approach 1:
The support structure is divided into multiple segments including a first support member, second support member, third support member, and fourth support member that are coupled to each other. These segmented support members are positioned at different locations (first, second, third, and fourth bent areas) to provide distributed reinforcement across the curved display surface, maintaining design versatility while improving impact resistance through localized support.
Solution Approach 2:
The invention employs a composite support structure combining multiple support members made of different materials or configurations. The first and second support members are coupled to the first bent area, while the third and fourth support members are coupled to the second bent area, creating a composite reinforcement system that enhances mechanical strength at curved regions without compromising the overall curved design aesthetic.
2Shape
If the non-display area is positioned at the bent area to reduce the visible non-display area, then the aesthetic appearance is improved, but the mechanical strength and impact resistance at that location deteriorate
Solution Approach 1:
Support members are introduced as intermediary elements between the curved display surface and the non-display area at bent regions. The first support member is coupled between the first bent area and the first non-display area, while the second support member is coupled between the second bent area and the second non-display area. These intermediary support members transfer and distribute mechanical loads, allowing the non-display areas to be positioned at aesthetically pleasing bent locations without compromising structural integrity.
3Reliability
If support members are added to enhance impact resistance at bent areas, then the mechanical strength is improved, but the device complexity increases
Solution Approach 1:
Multiple support members are merged into an integrated support structure where the first support member, second support member, third support member, and fourth support member are coupled to each other to form a unified reinforcement system. This merged structure provides comprehensive impact resistance at all bent areas while presenting as a single cohesive component, thereby reducing the perceived complexity despite the multiple functional elements.
Solution Approach 2:
The support members serve multiple functions simultaneously: they provide mechanical reinforcement at bent areas, support the curved display surface, manage the positioning of non-display areas, and contribute to the overall structural stability. This multi-functionality reduces the need for separate components for each function, thereby managing device complexity while achieving comprehensive impact resistance.

AI summary
A display apparatus includes a window member, a display panel and a support member. The window member includes a window flat portion, and a window bent portion which extends bent from the window flat portion. The display panel includes an upper flat portion overlapping with the window flat portion, an upper bent portion extending bent from the upper flat portion to extend along the window bent portion, and a lower bent portion extending from the upper bent portion and bent toward a center of the upper flat portion. The support member disposes the display panel between the window member and the support member and extends along the lower bent portion of the display panel. Each of the upper flat portion and the upper bent portion is a display area of the display panel, and the lower bent portion is a non-display area of the display panel.
