Flexible Display Protective Cover for Rollable Edge Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In rollable electronic devices, the rollable display experiences slip between layers, leading to lifting of the display edge and vulnerability to external impact, particularly at the extension connecting to the flexible printed circuit board.
Innovation Solution
A protective cover is integrated between the fixed portion of the flexible display and the housing, creating a spaced first area to protect the extension from external impact and prevent lifting during roll-in/roll-out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display is made rollable to enable transformation and larger display area, then the display functionality is improved, but the edge portion becomes vulnerable to external impact and layer slip occurs
Solution Approach 1:
A protective cover is introduced as an intermediary component between the flexible display and the housing. This protective cover specifically protects the edge portion and extension of the flexible display from external impact during roll-in/roll-out operations, resolving the vulnerability caused by the rollable structure.
2Volume of moving object
If the extension is positioned close to the housing to save space, then the device structure is compact, but the extension is exposed to external impact
Solution Approach 1:
The protective cover serves as a mediator that allows the extension to be positioned close to the housing for compactness while simultaneously protecting it from external impact. The protective cover is disposed between the extension and the housing, creating a protective barrier without requiring additional space.
3Reliability
If the protective cover contacts the extension directly to protect it, then impact protection is provided, but the extension may still be vulnerable during roll-in/roll-out movement
Solution Approach 1:
The protective cover is designed with differentiated regions: a first region that contacts the upper portion of the edge portion for protection and support during roll-in/roll-out, and a second region that provides spacing between the extension and the protective cover. This local quality differentiation ensures both protection and smooth operation.
Solution Approach 2:
The protective cover is pre-positioned to contact the upper portion of the edge portion before any impact or slip occurs during roll-in/roll-out. This preliminary positioning provides support and prevents layer slip and peeling at the edge portion before damage can occur.

AI summary
An electronic device may include a first housing including an antenna provided on a side surface thereof, a second housing configured to slide in a first direction to be drawn out of the first housing and to slide in a direction opposite to the first direction to be drawn into the first housing, a flexible display including a first side comprising a fixed portion and a second side provided to be drawn out of an inside of the first housing or drawn into the inside of the first housing according to an operation of the second housing, and a protective cover provided between the fixed portion and the first housing to contact at least a portion of an upper portion of the fixed portion. A first space may be provided between the protective cover and a side portion of the fixed portion.
