Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If super-resolution processing is performed to improve image quality, then resolution is improved, but processing time increases and frame frequency decreases
Solution Approach 1:
The image processing is divided into multiple stages: first performing edge enhancement processing, then super-resolution processing, and finally local dimming and overdrive processing. This segmentation allows each process to operate efficiently on optimized input data, reducing overall processing time while maintaining high image quality
Solution Approach 2:
Edge enhancement processing is performed before super-resolution processing to pre-highlight important image features. This preliminary action reduces the complexity of subsequent super-resolution processing by emphasizing key edges and boundaries, enabling faster processing while maintaining or improving image quality
2Manufacturing precision
If multiple image processing steps are performed to improve image quality, then image quality is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts processing parameters based on image content and display conditions. Local dimming and overdrive processing are applied adaptively only where needed, reducing unnecessary power consumption while maintaining high image quality in critical areas
Solution Approach 2:
Processing parameters such as enhancement strength, resolution scaling factors, and timing are optimized based on image characteristics and display requirements. This allows the system to achieve high image quality with minimal power consumption by applying processing only when and where necessary
3Manufacturing precision
If processing steps are added to improve image quality, then image quality is improved, but device complexity increases
Solution Approach 1:
Multiple image processing functions (edge enhancement, super-resolution, local dimming, overdrive) are merged into a single integrated processing pipeline. This combining approach reduces device complexity by sharing common processing resources and data paths while maintaining the benefits of multiple processing stages

AI summary
The resolution of a low-resolution image is made high and a stereoscopic image is displayed. Resolution is made high by super-resolution processing. In this case, the super-resolution processing is performed after edge enhancement processing is performed. Accordingly, a stereoscopic image with high resolution and high quality can be displayed. Alternatively, after image analysis processing is performed, edge enhancement processing and super-resolution processing are concurrently performed. Accordingly, processing time can be shortened.
