Portable Terminal Dual Display Layout Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable information terminal devices with a single display screen struggle to effectively display multiple information items, as they often require superimposing or scrolling, making it difficult for users to view various data types, such as images and text, in an appropriate layout.
Innovation Solution
A portable information terminal device with multiple display portions, where a video control portion dynamically sets layouts based on conditions, allowing for single or multiple information items to be displayed on each screen, depending on the operation state or received information, using a display information list to allocate and prioritize content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple information items are displayed on a single display screen, then the device complexity is reduced, but the ease of operation deteriorates because information becomes hard to view
Solution Approach 1:
The patent divides the display function into multiple independent display screens (first display screen, second display screen, third display screen) instead of using a single screen. Each screen can independently display different information items, allowing users to view multiple pieces of information simultaneously without cluttering a single display space. This segmentation resolves the contradiction by maintaining simple device architecture while improving information visibility and ease of operation.
2Device complexity
If a fixed display layout is used, then the device complexity is reduced, but the adaptability deteriorates because the layout cannot change dynamically
Solution Approach 1:
The patent implements dynamic layout control where the display configuration changes automatically based on the type of received information. The control unit determines the appropriate display layout (single-screen or multi-screen) and allocates information to specific displays based on real-time conditions. This dynamic adaptation allows the system to adjust its behavior without requiring complex manual reconfiguration, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The system changes display parameters such as the number of active display screens, the allocation of information items to specific screens, and the layout configuration based on the type of received information. For example, image information may be displayed on one screen while text information is displayed on another screen. This parameter change mechanism provides adaptability while maintaining relatively simple control logic.
3Ease of operation
If information is allocated to specific display screens based on type, then the ease of operation is improved, but the adaptability deteriorates because only one display screen can be used for a given information type
Solution Approach 1:
The patent makes each display screen multi-functional by enabling them to display different types of information (images, text, moving images) depending on the allocation. The control unit can assign any received information to any available display screen based on the information type and user needs. This universality allows the system to maintain ease of operation through dedicated display assignments while preserving adaptability by allowing flexible reassignment of different information types to different screens.

AI summary
In the portable information terminal device 1a, when a second display portion 9 is flipped over to the front of the portable information terminal device 1a, a first display portion 3 and the second display portion 9 are visible from a user at the same time. The display layouts of the first display portion 3 and the second display portion 9 are switched automatically in accordance with the visibility status of the respective display screens. The display layouts are also switched automatically in response to a change in information to be displayed. Therefore, a plurality of information items can be displayed in an appropriate layout that is easy to grasp to the user.
