Foldable Display Panel Bending Area Overlap Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies face challenges in achieving a "full screen" display effect with flexible and foldable designs, particularly in integrating electronic elements without occupying display space, especially in devices like mobile phones and computers.
Innovation Solution
A display panel design featuring a first display area with a planar area and a bending area, where the planar area has a longer length than the second display area, allowing for overlap in a bent state, thereby creating a shelf space for electronic elements and enabling a full screen display without occupying display panel space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic elements are integrated into the display panel, then device functionality is improved, but display area is reduced
Solution Approach 1:
The patent utilizes the bending area to create spatial overlap between the first and second display areas when bent, effectively using the third dimension (depth/overlap) to accommodate electronic elements without reducing the apparent display area. The planar area extends beyond the second display area in the second direction, creating shelf space for electronic elements when the display is bent along the first direction.
Solution Approach 2:
The patent implements nesting by placing electronic elements within the shelf space created by the overlapping display areas. The first display area's planar area contains the electronic elements when bent, allowing the display panel to hold its own components within its structure without external housing space.
2Adaptability or versatility
If display panel is made flexible with bending area, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The display panel is segmented into three distinct areas: a first display area with a planar area and a bending area, a bending area, and a second display area. This segmentation allows each area to be optimized independently - the planar area for electronics integration, the bending area for flexibility, and the second display area for additional display functionality.
Solution Approach 2:
Different areas of the display panel have different properties: the planar area is designed with greater maximum length to provide shelf space, the bending area is optimized for flexibility and bending radius, and the second display area has adjusted dimensions. This local differentiation of properties allows the overall system to achieve flexibility while maintaining manufacturability through localized optimization.

AI summary
A display panel includes a first display area and a second display area. The first display area includes a planar area and a bending area. The first display area and the second display area are arranged along a first direction. The planar area and the second display area are arranged at opposite sides of the bending area along the first direction. A maximum length of the planar area along a second direction is greater than a minimum length of the second display area along the second direction. The first direction intersects the second direction.
