Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices have a significant bezel that reduces the perceived size of the display area and affects aesthetic appeal.
Innovation Solution
A display device design featuring a flat area and a bending area with a protective window and a high-refractive member in the bending area, which adjusts the light path to increase the display area perceived by the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conventional protective window design is used, then the protective window provides adequate protection, but the bezel size remains large and the perceived display area is reduced
Solution Approach 1:
The protective window is designed with spatially varying thickness: a first thickness in the flat area and a second (reduced) thickness in the bending area. This local differentiation allows the bending area to extend further while maintaining protection, effectively reducing the bezel and increasing the perceived display area without compromising overall protective function.
Solution Approach 2:
The thickness parameter of the protective window is changed across different regions. By reducing the thickness in the bending area compared to the flat area, the design enables greater curvature extension with the same material volume, thereby reducing bezel size and increasing perceived display area while maintaining adequate protection.
2Area of stationary object
If the protective window thickness is reduced in the bending area, then the perceived display area increases, but the protective function may be compromised
Solution Approach 1:
The protective window provides different thickness levels at different locations: sufficient thickness in the flat area for robust protection, and reduced thickness in the bending area to extend the display perimeter. This local quality differentiation maintains protective function where needed while maximizing perceived display area in the bending region.
Solution Approach 2:
The protective window applies full thickness protection in the critical flat area where structural integrity and protection are paramount, while applying reduced thickness in the bending area where the primary goal is to extend the perceived display area. This partial action approach optimizes the balance between protection and display area.
