Display Terminal Mode Switching for Portrait Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display terminals, such as televisions, often exhibit significant blank areas when displaying content in portrait mode, leading to reduced screen utilization and a poor user viewing experience due to their landscape-oriented design.
Innovation Solution
A method and system for adjusting the display terminal's mode based on image and screen size ratios, adjusting the image to fit the available screen area optimally, and determining the most suitable display mode (landscape or portrait) to minimize blank spaces, thereby enhancing screen utilization and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display terminal uses landscape display mode, then it is suitable for displaying contents in landscape mode, but it causes large blank areas when displaying portrait mode contents, reducing screen utilization rate
Solution Approach 1:
The patent implements dynamic display mode switching between landscape and portrait modes based on the aspect ratio of the input image. The system calculates the image aspect ratio and automatically selects the optimal display orientation, making the display terminal adaptable to different content types rather than being fixed in landscape mode only.
Solution Approach 2:
The patent changes the display parameters (display mode, adjustment ratios) based on the image characteristics. By calculating the image aspect ratio and comparing it with the screen aspect ratio, the system adjusts the display mode and scaling parameters to minimize blank areas and maximize screen utilization for different content types.
2Ease of operation
If the display terminal displays portrait mode contents in landscape mode, then the display terminal can maintain its default landscape orientation, but the viewing experience is greatly reduced due to large blank areas
Solution Approach 1:
The display terminal automatically determines the optimal display mode and adjusts itself without user intervention. The system calculates the image aspect ratio, compares it with the screen aspect ratio, and automatically selects the appropriate display mode and scaling parameters, making the terminal self-adapting to different content requirements.
Solution Approach 2:
The patent implements dynamic adjustment of display parameters based on real-time image characteristics. The system can switch between landscape and portrait modes dynamically, and adjust scaling ratios automatically, providing an optimized viewing experience for different content types while maintaining ease of operation.
3Device complexity
If the display terminal uses fixed landscape display mode, then the device structure is simple, but it reduces screen utilization rate when displaying portrait mode contents
Solution Approach 1:
The display terminal performs automatic aspect ratio calculation and display mode selection without requiring complex user controls or manual configuration. The system self-determines the optimal display parameters based on the input image characteristics, achieving high screen utilization through automated decision-making rather than fixed manual settings.

AI summary
A display terminal adjustment method is provided, this method includes: obtaining image data of an image to be displayed and screen data of the display terminal; obtaining a first adjustment ratio and a second adjustment ratio according to an image size in the image data and a screen size in the screen data; adjusting the image to be displayed to obtain a first target image according to the first adjustment ratio, and adjusting the image to be displayed to obtain a second target image according to the second adjustment ratio; and adjusting the display terminal to be in a target display mode according to the first target image and the second target image, according to this method, a size of a blank area of the display terminal is reduced, and an utilization rate of the screen of the display terminal is improved.
