Rotating Display Control for Full-Screen Portrait Mirroring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen mirroring technologies require users to go through complex procedures and do not automatically adjust display orientation when switching between portrait and landscape modes, leading to suboptimal viewing experiences.
Innovation Solution
A display apparatus and controlling method that automatically rotates the display based on direction information received from an external device via a remote controller, using a communicator, motor, and processor to ensure proper orientation and full-screen viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If screen mirroring is performed on a landscape device, then the display can show content, but portrait-oriented image content cannot be displayed in full screen
Solution Approach 1:
The display device dynamically changes its orientation from landscape to portrait mode based on the orientation of the external device being mirrored. The processor detects the external device's orientation and controls the motor to rotate the display panel accordingly, allowing the display area to adapt dynamically to match the content orientation.
Solution Approach 2:
The system changes the display orientation parameter (from fixed landscape to variable portrait/landscape) based on the external device's orientation. This parameter change enables the display to accommodate different content orientations while maintaining full-screen display capability.
2Ease of operation
If automatic orientation detection is implemented, then full-screen display is achieved, but device complexity increases
Solution Approach 1:
The display device automatically detects the orientation of the external device and adjusts its own display orientation without requiring user intervention. The processor autonomously receives orientation information, determines the appropriate display mode, and controls the motor to rotate the display panel accordingly.
Solution Approach 2:
The processor acts as an intermediary that receives orientation information from the external device through the communicator, processes this information, and translates it into motor control signals for display rotation. This intermediary function simplifies the overall system by centralizing the control logic.
3Device complexity
If manual screen mirroring setup is used, then device complexity is reduced, but user operation time increases
Solution Approach 1:
The system performs automatic device pairing and orientation detection without requiring users to manually execute screen mirroring applications or select sink devices. The communicator automatically establishes connection based on device information, and the processor automatically configures the display orientation based on detected external device orientation.
Solution Approach 2:
The system pre-configures the display orientation based on the external device's orientation information before actual content mirroring begins. This preliminary action eliminates the need for users to manually adjust settings during the screen mirroring process.
