Display Control for Dual-Screen Orientation Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of dual-touch panel smartphones or tablets face difficulties in easily viewing images due to the limitations in how images are displayed across the two screens when the device is in different orientations or states, such as portrait and landscape modes.
Innovation Solution
A display apparatus with a control system that adjusts the display of page images based on the orientation and state of the device, arranging them horizontally or vertically, and changing their size to optimize viewing, depending on whether the device is in a folded or unfolded state and the orientation of the screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If images are displayed to match the device orientation (portrait/landscape), then image viewing quality is improved, but the display layout complexity increases
Solution Approach 1:
The display control section dynamically adjusts the display layout based on real-time detection of device orientation (portrait or landscape mode). When the device is in portrait mode, images are displayed vertically; when in landscape mode, images are displayed horizontally. This dynamic adaptation resolves the contradiction by automatically matching the display orientation to the device orientation, improving image viewing quality without requiring manual user configuration.
Solution Approach 2:
The system changes the display parameter (layout orientation) based on the device orientation state. The control section detects whether the device is in portrait or landscape mode and accordingly switches between vertical and horizontal display layouts. This parameter change approach allows the display to adapt to different orientations, resolving the contradiction between viewing quality and layout complexity.
2Productivity
If multiple page images are displayed simultaneously, then information efficiency is improved, but the size of each individual image decreases
Solution Approach 1:
The display control section segments the display area to show multiple page images simultaneously when the device is in a specific orientation (e.g., landscape mode). By dividing the screen into multiple regions, the system can display multiple pages at once, improving information efficiency. The segmentation is dynamically adjusted based on device orientation, allowing users to view multiple pages when needed while maintaining full-screen view when a single page is sufficient.
Solution Approach 2:
The system dynamically switches between single-image and multi-image display modes based on device orientation. In portrait mode, only one large image is displayed; in landscape mode, multiple smaller images are displayed side-by-side. This dynamic switching resolves the contradiction by allowing users to choose the appropriate display mode based on their viewing needs and device orientation.

AI summary
When a page image is to be displayed, a display apparatus changes a display mode in which the page image is displayed on a display section according to both the orientation of the page image and the orientation of the display section.
