Rollable Display Support Structure for Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rollable display apparatuses are vulnerable to external impacts due to their thin design, which can lead to damage and reduced functionality.
Innovation Solution
The display apparatus includes a rollable display panel supported by a support member featuring a base part, multiple support bars, and a protruding part with first and second support portions. This configuration enhances impact resistance by distributing the force across the support bars and base part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display apparatus is designed with a thin profile to enable easy rolling, then the portability and rollability are improved, but the impact resistance deteriorates
Solution Approach 1:
The support member is divided into multiple functional segments: a base part for overall support, multiple support bars extending in the rolling direction for linear support, and protruding parts with support portions for localized reinforcement. This segmentation allows each component to contribute to impact resistance while maintaining the thin profile needed for rollability.
Solution Approach 2:
The support member combines multiple structural elements (base part, support bars, protruding parts) into a composite structure that provides enhanced impact resistance. The composite design allows the thin display apparatus to achieve sufficient strength by distributing impact forces across multiple components rather than relying on a single thick structure.
2Strength
If support structures are added to improve impact resistance, then the strength is improved, but the device complexity increases
Solution Approach 1:
The base part, support bars, and protruding parts are integrated into a single unified support member structure. This merging approach consolidates multiple support functions into one component, reducing the number of separate parts and assembly steps while maintaining comprehensive impact protection.
Solution Approach 2:
The support member serves multiple functions simultaneously: the base part provides overall structural support, the support bars prevent bending during rolling and provide linear support, and the protruding parts with support portions offer localized reinforcement. This multi-functionality reduces the need for separate components for each function.

AI summary
A display apparatus includes a display panel rollable around a rolling axis extending in a first direction and a support member disposed below the display panel. The support member includes a base part, support bars each extending in the first direction, arranged in a second direction crossing the first direction, and coupled to the base part, and a protruding part including a first support portion and a second support portion, each of which is disposed below the base part and extends in the second direction. The first support portion overlaps at least a portion of first ends of the support bars, and the second support portion overlaps at least a portion of second ends of the support bars, which are spaced apart from the first ends in the first direction.
