Multi-Screen Display Device for Aspect Ratio Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices with a 16:9 aspect ratio struggle to display images with aspect ratios of 4:3 and 21:9 without deformation, leading to unsatisfactory viewing experiences due to the need for compression or stretching, which results in black bars and reduced image size.
Innovation Solution
A display device comprising a main screen and sub-screens with adjustable pixel ratios, allowing the main screen to display images matching its aspect ratio while sub-screens handle mismatched aspect ratios by stretching, compressing, and segmenting the image to maintain full-screen display without deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the source image signal with aspect ratio 4:3 is displayed in full screen on a 16:9 display device, then the image covers the entire screen area, but the image is deformed due to compression or stretching
Solution Approach 1:
The display device is divided into multiple independent display areas (main display area and sub display areas) that can be independently controlled. This segmentation allows different portions of the image to be displayed in different areas with different aspect ratios, enabling full-screen display without deformation by distributing the image content across multiple segments.
2Area of stationary object
If the source image signal with aspect ratio 21:9 is displayed in full screen on a 16:9 display device, then the image covers the entire screen area, but the image is deformed due to compression in the transverse direction
Solution Approach 1:
The display device is divided into multiple independent display areas (main display area and sub display areas) that can be independently controlled. This segmentation allows different portions of the image to be displayed in different areas with different aspect ratios, enabling full-screen display without deformation by distributing the image content across multiple segments.
3Shape
If black portions are added to maintain the original aspect ratio of the source image signal, then the image is displayed without deformation, but the effective display area is reduced
Solution Approach 1:
The display device is divided into multiple independent display areas (main display area and sub display areas) that can be independently controlled. This segmentation allows different portions of the image to be displayed in different areas with different aspect ratios, enabling full-screen display without deformation by distributing the image content across multiple segments.
Solution Approach 2:
The solution transitions from a two-dimensional display (single screen) to a multi-dimensional display arrangement by adding sub display areas in different spatial dimensions. This allows the system to accommodate various aspect ratios by utilizing the additional spatial dimension, effectively eliminating the need for black bars while maintaining full-screen coverage.
4Device complexity
If a single main display screen with fixed aspect ratio is used, then the device structure is simple, but it cannot adapt to different aspect ratios of source image signals
Solution Approach 1:
The display device is divided into multiple independent display areas (main display area and sub display areas) that can be independently controlled. This segmentation allows different portions of the image to be displayed in different areas with different aspect ratios, enabling full-screen display without deformation by distributing the image content across multiple segments.
Solution Approach 2:
The display device employs dynamic control mechanisms that can adjust the activation and configuration of sub display areas based on the aspect ratio of the input signal. This dynamic adaptability allows the system to switch between different display modes (single screen or multi-screen) and configure the display areas to match various aspect ratios, thereby achieving versatility without excessive complexity.
