Patterned Display Support Plate for Rollable Screen Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays face challenges in efficiently supporting and managing the expansion and contraction of flexible display areas, leading to potential damage and reduced user convenience.
Innovation Solution
A flexible display system comprising a first and second housing, a flexible display with extendable areas, and a support structure featuring patterned plates and bars that alternately support the display, allowing for smooth rolling and extension while minimizing stress on the display material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible display area is extended to improve user convenience and portability, then the display can be rolled in or out based on housing movement, but the display may suffer from potential damage due to lack of adequate support during expansion and contraction
Solution Approach 1:
The plate is divided into multiple pattern areas (first pattern areas with separated shapes and second pattern areas with connected shapes) that provide distributed support points along the extended display area. This segmentation allows the display to be supported at multiple locations during expansion and contraction, preventing damage while maintaining flexibility and user convenience.
2Volume of moving object
If the second display area is configured to be rolled in or out to enhance portability, then the device becomes more compact, but the support structure must manage stress and potential damage during movement
Solution Approach 1:
Different pattern areas of the plate provide different support characteristics: first pattern areas with separated shapes provide support at discrete points, while second pattern areas with connected shapes provide continuous support. This local variation in support quality allows the structure to manage stress distribution appropriately during rolling movements, protecting the display material while enabling compactness.
3Stability of the object's composition
If patterned plates with separated and connected shapes are used to support the extended display area, then stability during expansion is improved, but the device complexity increases
Solution Approach 1:
The plate integrates both first pattern areas with separated shapes and second pattern areas with connected shapes into a single unified structure. This merging of different support patterns into one component provides stable support during expansion and contraction while avoiding the complexity of multiple separate support elements.

AI summary
An electronic device include: a first housing; a second housing that can move with respect to the first housing; and a first display area and a second display area extending from the first display area. The second display area can be rolled-in/rolled-out together with the second housing. A plurality of bars are arranged under the second display area, and a plate is disposed between the second display area and the plurality of bars so as to support at least a portion of the second display area. The plate includes first pattern areas and second pattern areas that are alternately arranged. The shape of the second pattern areas is different from the shape of the first pattern areas. The first pattern areas are arranged to not face the plurality of bars, and each of the second pattern areas is arranged to face a bar.
