Adaptive Rollable Display Concurrent Front Back Content Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication devices with flexible displays lack the ability to concurrently manage and present different content on both front and rear sides, limiting their functionality in supporting multiple users with distinct interfaces.
Innovation Solution
An electronic device with a rollable display that can slide between fully retracted and fully extended positions, featuring a controller that generates and presents different content on the front and back displays based on images captured by image capturing devices, allowing concurrent use by multiple users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a flexible display is rolled onto the back side of the device housing, then the front dimension is reduced, but the ability to concurrently manage and present different content on front and back sides is lost
Solution Approach 1:
The patent divides the display system into two independent segments: a front display portion and a back display portion. The controller separately manages each display, allowing independent content presentation on front and back sides simultaneously. This segmentation enables the device to maintain reduced front dimension while regaining concurrent content management capability.
Solution Approach 2:
The flexible display serves multiple functions by being configurable in different positions and modes. It can be fully extended for single-user front display, fully retracted for reduced front dimension with back display, or partially retracted to enable concurrent front and back display operations. This multi-functionality resolves the contradiction between size reduction and versatility.
2Volume of moving object
If the display is fully retracted to reduce front dimension, then the device becomes more compact, but concurrent use by multiple users with distinct interfaces is limited
Solution Approach 1:
The system segments the user interface into separate front and back display areas, each accessible to different users simultaneously. The controller identifies which user is interacting with which side and delivers appropriate content to each display, enabling multi-user concurrent access even when the display is fully retracted and only the back display is visible.
Solution Approach 2:
The controller acts as an intermediary that receives input from either front or back side, determines the appropriate user context, and routes content generation and display accordingly. This intermediary function enables seamless multi-user interaction without requiring the display to be physically extended.
3Area of stationary object
If the display is extended to provide larger front display area, then more content can be presented to front user, but the back display functionality is lost
Solution Approach 1:
The display system is made dynamic through the translation mechanism that can position the flexible display at different extents. The system dynamically adjusts between full extension (front display only), full retraction (back display only), and partial retraction (concurrent front and back display) based on operational requirements, resolving the contradiction between front display area and back display capability.
4Device complexity
If a single display is used for both front and back sides, then device complexity is reduced, but the ability to present different content to different users simultaneously is compromised
Solution Approach 1:
The system segments the single flexible display into functionally independent front and back display portions through software control. The controller treats each portion as a separate display device with independent content generation and management, enabling differential content presentation while maintaining the physical simplicity of a single flexible display component.

AI summary
An electronic device, method, and computer program product manage concurrent use of different portions of an adaptive rollable display device enabling the electronic device to differently support two local users. A first image is received from a first image capturing device of the electronic device. The first image capturing device is disposed in one of a front side and a back side of a device housing of the electronic device and has an associated field of view extending from a respective side of the device housing. First user content is generated based at least in part on the first image and presented on a corresponding one of a front display and back display(s) corresponding to the first user. Second user content is generated based at least in part on the first image and presented on another one of the front display and the back display(s) corresponding to a second user.
