Rotating Display Control for Full-Screen Screen Mirroring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen mirroring technologies require users to go through cumbersome procedures and do not automatically adjust display orientation when switching between portrait and landscape modes during screen mirroring, 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 in landscape direction sink device, then the display can show content, but portrait-oriented image content is not displayed in full screen
Solution Approach 1:
The display apparatus dynamically changes its orientation from landscape to portrait mode based on the orientation of the external device. The processor detects the orientation information from the external device and controls the display to rotate accordingly, allowing the display area to adapt dynamically rather than being fixed in one orientation.
Solution Approach 2:
The system changes the display parameter (orientation angle) based on the external device's orientation. When the external device is in portrait mode, the display rotates 90 degrees to match, ensuring that the content maintains its intended orientation and fills the screen properly.
2Ease of operation
If automatic rotation is implemented, then full-screen viewing is achieved, but device complexity increases
Solution Approach 1:
The display apparatus automatically detects the orientation of the external device and adjusts its own orientation without requiring manual user input. The system serves itself by autonomously making the rotation decision and executing the rotation, eliminating the need for user intervention while maintaining simplicity.
Solution Approach 2:
The system receives orientation feedback from the external device through communication protocols. The processor uses this feedback information to determine the appropriate rotation angle and executes the rotation accordingly, creating a closed-loop control system that adapts to the external device's state.
3Reliability
If manual screen mirroring setup is required, then connection can be established, but user convenience deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically detecting the external device and initiating the connection process before the user needs to manually set anything up. The display apparatus proactively searches for and identifies compatible external devices, preparing the connection in advance.
Solution Approach 2:
The display apparatus autonomously handles the connection establishment process by detecting external devices and initiating mirroring connections without requiring the user to manually configure settings. The system serves itself by automatically managing the entire connection workflow.

AI summary
Disclosed are a display apparatus and a controlling method thereof. The display apparatus includes a communicator including a circuitry; a display; a motor configured to rotate the display; a memory storing at least one instruction; and a processor configured to execute the at least one instruction to: control the communicator to communicatively connect to an external device based on information related to the display apparatus that is received by the external device from a remote controller to which the external device is tagged, obtain direction information of at least one of the external device and of an image content displayed on the external device, determine, based on the direction information, whether to control the motor to rotate the display, and control the display to display the image content that is received from the external device through the communicator.
