Rollable Display Segmentation and Navigation Bar Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a rollable display is expanded, the distance between the user's fingers and the display areas becomes too large, making it uncomfortable and difficult to control the out-of-reach areas with one hand, leading to user inconvenience.
Innovation Solution
An electronic device with a flexible housing and display that includes a rigid area for always-exposed output and a ductile area for expanded output, where the user can control applications in both areas using a navigation bar in the ductile area, providing visual feedback and allowing easy access to all display regions.

Engineering Contradiction Analysis
1Area of stationary object
If the rollable display is expanded to provide a large screen area, then the display area is improved, but the ease of operation deteriorates because the distance between the user's fingers and the display areas becomes too large
Solution Approach 1:
The display area is segmented into a first area (always-exposed portion) and a second area (unrolled portion), allowing different interaction modes for different regions. The first area remains within easy reach for direct operation, while the second area provides extended display space without requiring the user to reach distant locations.
Solution Approach 2:
A navigation bar is introduced as an intermediary control interface located in the ductile area. This navigation bar provides visual feedback and allows easy access to control functions for both the first and second areas, eliminating the need for users to directly reach distant portions of the expanded display.
2Productivity
If the rollable display is unrolled to execute multiple applications simultaneously, then the productivity is improved, but the device complexity increases due to the need to manage multiple display areas and control interfaces
Solution Approach 1:
The navigation bar serves multiple functions: it provides visual feedback for the current display state, enables control of applications in both the first and second areas, and allows switching between different display configurations. This multi-functional design reduces the need for separate control interfaces for each display area.
Solution Approach 2:
The control functions for both the always-exposed portion and the unrolled portion are merged into a single navigation bar interface. This consolidation simplifies the control system by providing unified access to all display areas through one interface rather than requiring separate controls for each region.

AI summary
An electronic device includes a cover glass, a back cover facing the cover glass, a display including a rigid area exposed through the cover glass, in which a first application is output, and a ductile area extending from the rigid area, and a processor electrically connected to the display. When at least a portion of the ductile area is exposed, the processor may output the first application in a first area which is a portion of the rigid area and the ductile area and a second application in a second area which is a remaining portion of the rigid area.
