Flexible Display Edge Curtain for Mobile Terminal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with flexible displays face challenges in maintaining a stable extended state without exposing the display unit, leading to potential damage and aesthetic issues when the display is extended, as existing solutions fail to effectively protect the display edges and internal components.
Innovation Solution
A mobile terminal design featuring a first and second frame with a slide mechanism, a flexible display unit, and an edge curtain that moves with the second frame to cover the display edges, preventing exposure and damage, while allowing for deformation without disturbing the rolling plate's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the flexible display unit is extended to increase screen size, then the display area is improved, but the display unit end portion is exposed and vulnerable to damage
Solution Approach 1:
The patent employs a flexible case structure that can deform to cover the extended display unit. The case includes a first case portion and a second case portion that can slide relative to each other, with the second portion extending to cover the exposed end of the flexible display when in the extended state, preventing damage while allowing the display to remain flexible and extendable.
2Area of moving object
If the flexible display unit is extended, then the screen size is increased, but internal components are exposed to the outside
Solution Approach 1:
The patent implements a nested structure where the second case portion is positioned inside the first case portion when the display is in the retracted state, and only extends outward to cover the display end when extended. This nested arrangement allows the case to protect internal components during extension without permanently exposing them, maintaining a compact form when retracted.
3Object-affected harmful factors
If a protective structure is added to cover the extended display, then protection from damage is improved, but the device complexity increases
Solution Approach 1:
The patent employs a dynamic sliding mechanism where the second case portion can move between extended and retracted positions relative to the first case portion. This dynamic structure allows the protective cover to be automatically positioned based on the display state, providing protection only when needed while maintaining simplicity in the retracted state.
4Adaptability or versatility
If the display unit is made flexible and deformable, then the size variability is improved, but the stability of the extended state deteriorates
Solution Approach 1:
The patent divides the case into multiple segments: a first case portion and a second case portion that can slide independently. This segmentation allows the case to accommodate the flexible display's deformation while maintaining structural stability through the coordinated movement of the segmented parts, preventing the display from becoming unstable during extension.

AI summary
A mobile terminal comprises a first frame, a second frame slidably moving in a first direction to switch a first state to a second state, a slide frame slidably moving in the first direction to correspond to sliding of the second frame, a flexible display unit including a first region coupled to the first frame, a second region coupled to the slide frame, and a third region arranged between the first region and the second region and bent to surround the second frame, and an edge curtain covering an end portion in a third direction which is vertical to the first direction of a portion arranged in a front direction of the third region at the second state. A rolling plate may be covered so as not to be exposed in a front direction, whereby esthetic external appearance may be provided.
