Rotatable Display Orientation Control for Portrait Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart televisions face challenges in displaying vertical media resources due to mismatched aspect ratios, leading to wasted display space and poor user experience.
Innovation Solution
A rotatable display apparatus with a rotating assembly and a controller that detects the current rotation state of the display and adjusts it to a standard state, displaying an animation corresponding to the standard state after rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display maintains a fixed horizontal aspect ratio (16:9), then the display structure is simple and stable, but vertical media resources cannot be displayed properly causing wasted display space
Solution Approach 1:
The display structure is transformed from a fixed horizontal orientation to a dynamic structure that can rotate between horizontal and vertical orientations. The rotating assembly enables the display to adapt its orientation based on the media resource type, resolving the contradiction between structural simplicity and display adaptability.
Solution Approach 2:
The display apparatus is designed to perform multiple functions by supporting both horizontal and vertical display modes. The rotating assembly enables the same display hardware to serve different media formats (landscape and portrait), achieving multi-functionality without requiring separate display devices.
2Reliability
If vertical media resources are zoomed to fit the horizontal display, then complete display is achieved, but display space is wasted and user experience deteriorates
Solution Approach 1:
Instead of using static zooming that wastes display space, the system dynamically rotates the display to match the media resource orientation. This dynamic adjustment ensures complete display of vertical media resources while utilizing the full display area, thereby improving user experience.
3Adaptability or versatility
If the display rotates to match vertical media resources, then aspect ratio alignment is improved, but the system complexity increases due to rotation control
Solution Approach 1:
The system automatically detects the orientation of incoming media resources and autonomously controls the display rotation without requiring manual user input. This self-service approach handles the rotation control complexity internally while maintaining simplicity from the user perspective.
Solution Approach 2:
The system implements feedback control by detecting the media resource orientation and automatically adjusting the display rotation accordingly. This closed-loop control ensures proper aspect ratio alignment while managing the rotation control system's complexity through automated decision-making.

AI summary
Provided are a display apparatus and display method for the display apparatus with a rotatable display. A controller thereof is configured to, during a power-off state or standby state of the display apparatus, in response to an instruction for starting the display apparatus, detect a current rotation state of the rotatable display; in response to the rotatable display being in the horizontal state, control the display to present an animation for the starting of the display apparatus corresponding to the horizontal state; and in response to the rotatable display being in the portrait state, control the display to present an animation for the starting of the display apparatus corresponding to the portrait state.
