Curved Edge Display Panel Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses with larger bezels result in increased volume, necessitating a reduction in bezel size while minimizing damage to internal components.
Innovation Solution
A display apparatus design featuring a display part with a curved edge portion toward the image display direction, integrated with a housing that includes a window panel and touch sensor, and a polarizing plate, which minimizes bezel width and reduces component damage by applying compressive force to the display panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the bezel size is reduced to decrease the volume of the display apparatus, then the volume is reduced, but the structural integrity and protection of internal components may be compromised
Solution Approach 1:
The edge portion of the display part is curved in the direction toward which the image is displayed, forming an arc shape that provides structural reinforcement. This curvature allows the bezel to maintain strength while reducing overall size, as the arched structure naturally resists bending forces better than flat edges.
Solution Approach 2:
The curved edge portion acts as a pre-designed protective structure that cushions and distributes mechanical stress before it can reach internal components. By curving the edge toward the display direction, the design creates a buffer zone that absorbs impact forces, protecting the display panel and other sensitive elements within the reduced bezel space.
2Area of stationary object
If the bezel size is reduced to increase the display area ratio, then the display area ratio is improved, but the protection of internal components from damage may be insufficient
Solution Approach 1:
The curved edge portion extends from the flat portion and arcs toward the display direction, creating a reinforced border that protects internal components while minimizing the non-display area. This curvature provides structural support that maintains component protection even as the bezel size is reduced to maximize display area ratio.
Solution Approach 2:
The curved edge structure serves as a pre-engineered protective barrier that cushions external forces before they can damage internal components. By positioning this curved protection at the edge and orienting it toward the display direction, the design ensures component reliability while maintaining a high display area ratio.
3Volume of moving object
If the edge portion is curved toward the image display direction, then the bezel size is reduced, but stress concentration on the display panel may increase
Solution Approach 1:
The curved edge portion is designed with a specific curvature radius that distributes stress along the arc rather than concentrating it at sharp corners. By extending the curve from the flat portion and orienting it toward the display direction, the design creates a gradual transition that reduces stress concentration points while maintaining compact bezel dimensions.
Solution Approach 2:
The curved edge structure acts as a stress-distributing buffer that cushions external forces before they reach the display panel. The arc shape disperses applied stress across a larger area and redirects forces along the curve, preventing stress concentration on the panel while enabling reduced bezel size.
