Movable Flexible Display Assembly for Adjustable Screen Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face challenges in increasing display size without compromising portability, as the movement of components like antennas limits freedom of mounting and can lead to performance deterioration due to frequent movement.
Innovation Solution
An electronic device with a movable flexible display that includes a first assembly and a second assembly, where the flexible touchscreen display is mounted to accommodate a bendable portion that can extend or retract, allowing for adjustable display size and improved component mounting flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display region size is increased to show more content, then the display area is improved, but the portability and slimness of the device deteriorates
Solution Approach 1:
The patent implements a flexible display that can dynamically change its configuration between a folded state (smaller display area, thinner profile) and an unfolded state (larger display area, thicker profile). This dynamic transformation allows the device to adapt between portability and display size requirements based on usage context.
Solution Approach 2:
The flexible display is designed to fold into itself, with one portion nested within another when in the folded state. This nesting arrangement reduces the overall device thickness and volume while maintaining the capability to expand to a larger display area when unfolded.
2Adaptability or versatility
If the first construction and second construction are moved with respect to each other to enable flexible display configuration, then the display adaptability is improved, but the freedom of mounting electronic components deteriorates
Solution Approach 1:
The device is divided into a first construction and a second construction that can move relative to each other. This segmentation allows the display to be folded while maintaining separate mounting zones for electronic components in each construction, preserving manufacturing flexibility despite the movable configuration.
3Adaptability or versatility
If the first construction and second construction are installed movably with respect to each other to enable display expansion, then the display size adaptability is improved, but the performance of internal electronic components deteriorates due to frequent movement
Solution Approach 1:
Sensitive electronic components are extracted and mounted in the second construction that remains relatively stationary during display folding operations. This extraction isolates performance-critical components from the mechanical movement, allowing the display to be adaptable while maintaining component reliability.

AI summary
An electronic device (400) may include an assembly that enables varying a visible portion of a display (430) by extending and retracting a bendable portion (432) of the display. The extending and retracting of the bendable display is facilitated by a first assembly (410) on which a substantially planar visible portion of the display is disposed and a second assembly (420) slidably attached to the first assembly. A space is defined by the first and second assemblies in which a bent portion of the display is housed. When the first assembly is extended (e.g., opened) with respect to the second assembly, at least a portion of the bent portion of the display is extended so as to be visible, and when the first assembly is closed (e.g., retracted) with respect to the second assembly, the extended bent portion of the display is retracted into the space between the first assembly and the second assembly, and is no longer visible. Various constructions of the first and second assemblies and corresponding structures are provided..
