Extendable Display Sidewall Structure to Prevent Panel Wrinkling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face issues with wrinkling and exposure of display panel sides when extended or retracted, leading to potential damage from external impacts.
Innovation Solution
A display device design featuring a display module, an extension module, sidewall cases, and elastic members that allow controlled movement and extension/retraction, along with guide openings and support structures to maintain panel integrity and prevent exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device is extended or retracted, then the display module can be moved to improve user convenience, but the display panel may become wrinkled and portions may be exposed to external impacts
Solution Approach 1:
The sidewall cases are designed to move dynamically relative to the main case in the first direction, synchronized with the extension module's movement. This dynamic adjustment allows the sidewall cases to cover or expose portions of the display panel as needed, protecting the panel during retraction while allowing extension for use.
Solution Approach 2:
The first elastic members act as intermediary elements between the sidewall cases and the main case, providing controlled elastic forces that enable the sidewall cases to move and return to their initial positions. This elastic mechanism ensures smooth, controlled movement without direct mechanical coupling.
2Object-affected harmful factors
If the sidewall cases move in the third direction to cover exposed portions, then protection against external impacts is improved, but the device structure becomes more complex
Solution Approach 1:
The sidewall cases serve multiple functions: they provide structural support for the display device, guide the movement of the extension module through guide openings, and protect the display panel by covering exposed portions. This multi-functionality reduces the need for separate protective components.
Solution Approach 2:
The protective structure is segmented into multiple sidewall cases that can move independently relative to the main case. This segmentation allows each sidewall case to be controlled by individual elastic members, enabling precise, localized protection without requiring a complex overall structure.

AI summary
A display device includes a display module, an extension module that is disposed under the display module and that extends and retracts in a first direction, a main case that accommodates the extension module, and a plurality of sidewall cases that are spaced apart from each other in a second direction intersecting the first direction and that move in the first direction relative to the main case. The plurality of sidewall cases move in a third direction intersecting a plane defined by the first and second directions.
