Display Device Sub-Window Scaling for Aspect-Ratio Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to maintain user satisfaction when changing aspect ratios of game content, often resulting in enlarged image display errors due to unchanged positions and sizes of sub-windows during aspect ratio changes.
Innovation Solution
A display device and method that dynamically adjust the position and size of sub-windows based on aspect ratio changes, allowing for optimized full-screen output by identifying and enlarging specific partial areas within the image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display device maintains fixed positions and sizes of sub-windows during aspect ratio changes, then the device complexity is reduced, but enlarged image display errors occur and user satisfaction decreases
Solution Approach 1:
The patent implements dynamic adjustment of sub-window positions and sizes based on aspect ratio changes. The processor dynamically calculates new positions and sizes using transformation rules that map original coordinates to adjusted coordinates, allowing the display layout to adapt flexibly to different aspect ratios while maintaining image accuracy and user satisfaction
Solution Approach 2:
The patent changes the parameters of sub-windows (positions and sizes) in response to aspect ratio changes. By transforming coordinate parameters from the original aspect ratio to the new aspect ratio, the system maintains accurate image display without requiring complex control logic, as the transformation follows predictable geometric relationships
2Manufacturing precision
If the display device dynamically adjusts sub-window positions and sizes based on aspect ratio changes, then enlarged image display errors are minimized, but the device complexity increases
Solution Approach 1:
The system dynamically adjusts sub-window parameters based on detected aspect ratio changes, using automated transformation calculations that map original coordinates to new coordinates through standardized formulas, achieving accurate image display without manual intervention
Solution Approach 2:
The display device automatically detects aspect ratio changes and performs self-adjustment of sub-window positions and sizes through embedded transformation logic, eliminating the need for external control systems or complex user configuration while maintaining display accuracy
3Device complexity
If the display device uses simple full-screen output without partial area enlargement, then the device complexity is reduced, but the loss of information increases due to inability to preserve important image objects during aspect ratio changes
Solution Approach 1:
The patent segments the display area into multiple regions: a first area displaying the full image and a second area displaying an enlarged view of a specific partial area containing important image objects. This segmentation allows the system to preserve critical information while maintaining relatively simple processing by focusing enlargement on specific regions rather than the entire image
Solution Approach 2:
The patent applies different display qualities to different areas of the screen. The partial area containing important image objects is enlarged with higher detail and prominence, while other areas maintain standard display quality, optimizing information preservation without requiring complex processing across the entire image

AI summary
Provided is a display device including: a display, a communication interface comprising communication circuitry configured to communicate with a source device, and a processor configured to execute at least one instruction. When an aspect ratio of an image corresponding to content is changed, the display device may output an optimized full screen in response to the change of the aspect ratio.
