Protective Cover Structure for Rollable Display Edge Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rollable electronic devices with flexible displays face issues of slip between layers causing edge lifting and vulnerability to external impact, particularly at the extension connecting the display to the printed circuit board.
Innovation Solution
An electronic device design incorporating a protective cover between the fixed portion of the flexible display and the housing, with a space to accommodate the extension, preventing edge lifting and external impact damage, while maintaining antenna communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rollable display structure is implemented to enable display area transformation, then the display area and ease of carrying are improved, but the edge of the display becomes vulnerable to external impact and layer slip occurs causing edge lifting
Solution Approach 1:
A protective cover is introduced as an intermediary component between the flexible display edge and the housing. This protective cover specifically protects the extension area where the flexible display connects to the rigid structure, preventing external impact from reaching the vulnerable edge and connection points.
Solution Approach 2:
The protective cover is positioned in advance at the edge area of the flexible display to provide cushioning protection before external impact occurs. The cover creates a buffer zone that absorbs and distributes impact forces, preventing direct transmission to the vulnerable display edge and connection structures.
2Area of moving object
If the flexible display is made extendable and rollable, then the display area is increased, but slip between layers occurs causing the edge to lift
Solution Approach 1:
The protective cover acts as a stabilizing intermediary that contacts the upper portion of the flexible display's fixed edge. This contact prevents relative movement and slip between layers at the critical edge area, maintaining layer stability during display extension and retraction operations.
Solution Approach 2:
The protective cover provides localized stabilization specifically at the edge area where layer slip occurs during rolling operations. By focusing protection and stabilization at this critical local region rather than the entire display, the solution maintains layer stability where needed while preserving the overall flexibility and rollability of the display.

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.
