Flexible Display Support Structure for Expandable Viewing Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for electronic devices with flexible displays that can change their size to accommodate various content viewing needs while maintaining a compact form factor for easy carrying.
Innovation Solution
The electronic device features a first cover and a second cover that can move relative to each other, with a display that includes a first region always visible and a second region that can extend or retract, featuring a minimum radius of curvature between specific positions to maximize visible display area without increasing device size.

Engineering Contradiction Analysis
1Area of stationary object
If the display size is increased to provide various contents, then the content viewing capability is improved, but the device size increases making it harder to carry
Solution Approach 1:
The display transitions from a static fixed-size configuration to a dynamic reconfigurable configuration. The display can be divided into multiple regions (first display region, second display region, third display region) that can be independently controlled to display different content, allowing the effective display area to change based on user needs without physically expanding the device dimensions.
Solution Approach 2:
The display is segmented into multiple independent display regions (first display region, second display region, third display region) that can be selectively activated. This segmentation allows the system to provide various content viewing experiences by combining or individualizing these regions, effectively increasing display versatility without increasing overall device size.
2Adaptability or versatility
If the display is made flexible to change size, then the content viewing capability is improved, but the structural complexity increases
Solution Approach 1:
The display system implements dynamic reconfiguration capability where different display regions can be independently controlled and combined. The display can switch between displaying content in the first display region, second display region, third display region, or combinations thereof, providing adaptability without requiring complex mechanical moving parts.
Solution Approach 2:
Different regions of the display (first display region, second display region, third display region) can have different functional characteristics and be optimized for specific content types. Each region can be independently controlled to display different content, allowing local optimization of display quality for different content categories while maintaining overall system simplicity.

AI summary
An electronic device comprises: a first cover; a second cover configured to move with respect to the first cover; and a display including a first area and a second area extending from the first area, wherein: a first position having a minimum radius of curvature in the second area is located between a second position of the second area, in which the direction in which a virtual plane coming in contact with the second area bent to have a curvature in the first cover is oriented corresponds to the direction in which the first area is oriented, and a third position of the second area in which the direction in which the virtual plane is oriented is vertical to the direction in which the first area is oriented; and the direction in which the virtual plane coming in contact with the first position is oriented is slanted to be within a reference angular range with respect to the direction in which the first area is oriented.
