Foldable Display Orientation Control for Dual-Screen Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable information processing devices with flexible displays face challenges in properly controlling display orientation and mode switching when used as a two-screen structure, leading to inconsistent and inefficient user interface management.
Innovation Solution
An information processing device equipped with a processor that executes orientation detection and display control processing to split the screen area into multiple display areas, allowing for seamless mode switching between single and dual-screen modes without replacing displayed data, and adjusting display orientations based on user input and device posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If one display is split into two display areas to create a pseudo two-screen structure, then the device can function as two screens simultaneously, but the display orientation cannot be controlled independently for each screen
Solution Approach 1:
The patent segments the single display into two independent display areas (first display area and second display area) with independent orientation control. Each display area can be rotated independently around the hinge mechanism, allowing the first display area to have a first orientation and the second display area to have a second orientation that is independent of the first, thus enabling independent orientation control for each screen while maintaining the pseudo two-screen structure
2Device complexity
If display orientation is changed in a unit of the display when used as two screens, then the entire display rotates together, but proper control of individual screen orientation is lost
Solution Approach 1:
The patent implements dynamic orientation control where the display system can adapt its behavior based on the operating mode. In two-screen mode, each display area can be rotated independently with different orientations. The system dynamically adjusts the orientation of each display area based on user input and device state, allowing proper control of individual screen orientation while maintaining coordination when needed
3Ease of operation
If the display is used as a single screen, then orientation control is simple, but the device cannot function as a two-screen structure
Solution Approach 1:
The patent creates a universal display system that can function in multiple modes: single-screen mode with unified orientation control, and two-screen mode with independent orientation control for each display area. The same display hardware and control mechanism serve both functions, allowing the device to adapt to different usage scenarios while maintaining ease of operation through mode-based simplification

AI summary
An information processing device includes: a foldable one display; a memory which stores at least a program; a processor which executes the program stored in the memory; and a sensor which detects orientation of the own information processing device. By executing the program stored in the memory, the processor performs: orientation detection processing to detect orientation of a screen area of the display based on the detection result of the sensor; and display control processing in which the screen area is split into a plurality of display areas to display display-data in each of the plurality of display areas, respectively, and display orientation of each of the plurality of display areas is changed according to a change in the orientation of the screen area without replacing pieces of display data to be displayed respectively in the plurality of display areas.
