Rotating Display Interface Switching for Vertical Media Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart TVs face issues in displaying media with mismatched aspect ratios, leading to wasted screen space and poor user experience due to the inability to adapt to vertical media formats like videos and comics, which typically have aspect ratios different from the standard 16:9 landscape orientation.
Innovation Solution
A display device with a rotating component and controller that allows the screen to rotate to different orientations based on user command, determining if the current application supports the new orientation and either rotating the screen or displaying a prompt if it does not, thereby improving the display of media with various aspect ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen is rotated to match vertical media aspect ratios, then screen space utilization is improved, but device complexity increases due to the rotating component
Solution Approach 1:
The screen is made dynamically rotatable rather than fixed, allowing it to adapt its orientation based on the media being displayed. The rotating component enables the screen to switch between landscape and portrait modes, optimizing screen space utilization for different aspect ratios while managing the added mechanical complexity through controlled mobility.
2Adaptability or versatility
If the screen rotates automatically for all applications, then adaptability to different media formats is improved, but reliability deteriorates when applications do not support the new orientation
Solution Approach 1:
The system implements feedback by detecting whether the current application supports screen rotation before executing the rotation. The controller checks application compatibility information and only rotates the screen when the application explicitly supports the new orientation, thereby maintaining reliability while preserving adaptability for compatible applications.
Solution Approach 2:
The system performs preliminary checking of application support for screen rotation before actually rotating the screen. By预先 determining whether the application is compatible with rotated orientation, the system avoids unreliable display states and ensures that rotation only occurs when appropriate, balancing adaptability with reliability.
3Area of stationary object
If vertical media is scaled to full display, then screen space utilization is improved, but manufacturing precision deteriorates due to distortion
Solution Approach 1:
Instead of statically scaling and distorting the image, the system dynamically rotates the screen to match the media's native aspect ratio. This physical reorientation allows vertical media to occupy the full screen area without requiring distortionary scaling, thereby improving screen space utilization while preserving image quality and manufacturing precision.

AI summary
This disclosure can provide a display device, including a controller configured for determining whether an application interface of a current application supports a screen orientation after rotation; if so, outputting a rotation command so that a rotating component can drive the screen to rotate based on the rotation command; and if not, controlling the screen to display a prompt message, so that a user can determine whether to continue to control the screen to rotate via the prompt message if needed.
