Foldable Display Device with Protective Functional Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices are prone to damage from external impacts when their display surfaces are exposed due to folding or bending operations.
Innovation Solution
The electronic device incorporates a display part with specific folding and non-folding areas, and a functional part with a predetermined thickness that houses an electronic module, providing protection to the display surface and allowing for a wide display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display surface is exposed to the outside due to folding operation, then the display area is increased and accessibility is improved, but the display surface is likely damaged by external impacts
Solution Approach 1:
A functional part is introduced as an intermediary component between the display surface and external environment. This functional part includes electronic modules and is positioned to cover the display surface when the device is folded, acting as a protective mediator that prevents direct exposure to external impacts while allowing the display to remain accessible during use
2Adaptability or versatility
If electronic modules are disposed on the display area, then device functionality is enhanced, but the display area is reduced
Solution Approach 1:
Electronic modules are relocated from the two-dimensional display plane to a three-dimensional functional part that extends perpendicular to the display surface. This dimensional transition allows electronic modules to be positioned above or below the display area, eliminating spatial conflict between functional components and display region while maintaining both functionality and display area

AI summary
An electronic device includes: a display part including a first non-folding area, a second non-folding area, a first folding area, a third non-folding area, and a second folding area, where the first folding area is disposed between the first non-folding area and the second non-folding area and folded to have a first radius of curvature, and the second folding area is disposed between the second non-folding area and the third non-folding area and folded to have a second radius of curvature greater than the first radius of curvature; and a functional part disposed adjacent to the first non-folding area of the display part and having a predetermined thickness in a thickness direction of the display part. The functional part includes an electronic module disposed on an upper surface of the functional part, and the electronic module includes at least one of a camera module and a driving module.
