Display Direction Synchronization for Multi-Application Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information display devices, such as mobile phones, face challenges in coordinating the display directions of multiple applications, leading to user confusion and increased user burden due to independent display control of each application, resulting in differing orientations across screens.
Innovation Solution
An information display device with a judgment mechanism to assess and synchronize the display directions of multiple application screens by selecting a reference application for display control, ensuring all screens align in a consistent orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each application operates as an independent function with independent display control, then application functionality is maintained, but display directions differ across screens causing user confusion and increased user burden
Solution Approach 1:
The patent introduces a display direction management mechanism that acts as an intermediary between multiple independent applications and the display screens. This mechanism coordinates display directions across applications, selecting a reference application's display direction and applying it consistently across all applications, thereby reducing user confusion while maintaining application independence
Solution Approach 2:
The patent creates a universal display direction control system that serves multiple applications simultaneously. Instead of each application having separate display control, a single display direction management mechanism serves all applications, ensuring consistent display directions across different applications and screens
2Adaptability or versatility
If display control is performed independently for each application, then application-specific display requirements are met, but display directions may differ with each screen making displayed contents difficult to view
Solution Approach 1:
The display direction management mechanism serves as an intermediary that ensures reliable and consistent display directions across all applications. It coordinates the display directions of multiple applications, preventing inconsistencies that would make displayed contents difficult to view, while still allowing applications to meet their specific display requirements through the reference application mechanism
3Ease of operation
If a reference application is selected for display control coordination, then display direction consistency is achieved, but additional control logic is required
Solution Approach 1:
The display direction management mechanism automatically selects a reference application and coordinates display directions without requiring user intervention. The system self-manages the complexity of controlling multiple applications' display directions, achieving consistency while keeping the user interface simple and intuitive

AI summary
In a terminal device, when application screens of a plurality of types of applications are being displayed individually and the display directions thereof differ from each other, a control section selects any one of the plurality of types of applications as a reference for display control, and orients the display direction of an application that is not the control reference to the display direction of an application that is the control reference. That is, when the display direction of an application displayed on one display section is changed from a vertical direction to a horizontal direction, the display direction of an application displayed on another display section is changed from the vertical direction to the horizontal direction so as to follow the foregoing change.
