Dual Display Mobile Terminal Segmentation for Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with scheduler and address book applications face challenges in managing and displaying personal and business-related information separately, making it difficult for users to view desired schedule or address information without mixing personal and business data.
Innovation Solution
A mobile terminal device with two display modules and a control module that switches between states to display different groups of information, allowing users to view personal or business-related schedule and address information on one display while keeping the other private when the device is in a closed or open state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single display is used in mobile devices, then the device structure is simple and cost is reduced, but users cannot separately view personal and business information
Solution Approach 1:
The mobile device is divided into two distinct display modules: a first display and a second display. The control module selectively activates these displays based on operational states. When the second housing is closed, only the first display is activated for private information. When opened, the second display is activated for public information, enabling separate viewing of personal and business data.
Solution Approach 2:
The system dynamically switches between different display configurations based on the operational state. The control module detects whether the second housing is closed or open and accordingly activates only the appropriate display module, creating a dynamic adaptation to usage context without requiring both displays to be permanently active.
2Ease of operation
If both display modules are always active, then users can access both personal and business information simultaneously, but power consumption increases and privacy protection is reduced
Solution Approach 1:
The control module dynamically controls display activation based on housing state. When the second housing is closed, only the first display module is activated, conserving power. When the housing is opened, the second display module is activated. This dynamic switching ensures that only the necessary display is active at any given time, optimizing power consumption while maintaining accessibility.
Solution Approach 2:
The system extracts and activates only the specific display module needed for the current operational context. Instead of keeping both displays permanently active, the control module selectively activates only the first display when the housing is closed and only the second display when opened, removing unnecessary power consumption from inactive displays.
3Ease of operation
If both display modules are always active, then information accessibility is improved, but privacy protection is weakened as personal information may be exposed
Solution Approach 1:
The display system is segmented into two independent modules with distinct functional assignments. The first display is dedicated to private information when the housing is closed, while the second display handles public information when opened. This physical and functional segmentation ensures that personal information displayed on the first display cannot be viewed when the device is in the closed state, providing inherent privacy protection.
Solution Approach 2:
The control module dynamically adjusts which display is active based on housing state, creating a privacy-protective mechanism. When the second housing is closed, only the first display is active for private information. When opened, the second display becomes active for public information. This dynamic state-dependent activation prevents accidental exposure of personal information while maintaining ease of access to both types of data.

AI summary
A method for operating a mobile terminal device comprising at least two displays is disclosed. Information of a first group on a first display module is displayed, if only a first display module is externally exposed. Information of a second group different from the first group on the first display module and a second display module is displayed, if both the first display module and the second display module are externally exposed.
