Flexible Display Controller for Rolled State Grip Exclusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices that can change shape, such as being rolled, face challenges in effectively displaying screens on transformed surfaces while maintaining user interaction and usability.
Innovation Solution
Incorporating sensors to detect exposed areas and user grip regions, allowing a controller to adjust the display to show screens only on exposed areas, excluding the grip area, and to move objects off the grip area, with animation effects, and to adapt screen size and shape based on the device's rolled state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is rolled to transform shape, then portability and flexibility are improved, but the usable display area is reduced due to user grip coverage
Solution Approach 1:
The display device dynamically adjusts the screen layout and object positions based on the detected rolled state and user grip area. The controller modifies the display configuration in real-time to maximize the usable display area while maintaining the flexible rolled shape, allowing the system to adapt between portability and display area requirements
Solution Approach 2:
The system identifies the user grip area as a distinct region with different functional requirements than the rest of the display. By applying local quality principles, the display excludes the grip area from showing interactive objects while maintaining display functionality in the non-grip exposed area, optimizing the layout for each specific region's purpose
2Ease of operation
If objects are moved from the grip area to the exposed area, then user interaction is improved, but screen layout complexity increases
Solution Approach 1:
The system pre-establishes rules and algorithms for object relocation based on detected grip areas. When the display is rolled and user grip is detected, the controller automatically applies predetermined layout adjustment strategies to move objects from the grip area to the exposed area, reducing the need for complex real-time decision-making during user interaction
3Adaptability or versatility
If the display adapts screen layout based on rolled state, then display appropriateness is improved, but processing requirements increase
Solution Approach 1:
The system changes display parameters such as screen resolution, object positions, and layout configuration based on the detected rolled state and exposed area. By adjusting these parameters dynamically, the display adapts to different shapes and usage scenarios while maintaining energy efficiency through targeted parameter modification rather than complete system reconfiguration

AI summary
A flexible display device including: a flexible display; a first sensor configured to sense an exposed area of the display which is exposed in a rolled state of the display; a second sensor configured to sense a user grip area within the exposed area, the user grip area corresponding to a user grip; and a controller configured to, in response to the exposed area and the user grip area being sensed, control the display to display a screen on the exposed area excluding the user grip area.
