Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current error detection methods in display devices incur a high processing load due to the need to calculate expectation values for all image data, leading to excessive data usage and potential undetected errors in regions not subjected to error detection.
Innovation Solution
A circuit device with an interface unit that receives image data and error detection data, including position information for specific error detection regions, allowing flexible setting of error detection regions and reducing processing load by performing error detection only on specified areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error detection is performed on all image data, then error detection coverage is improved, but processing load increases
Solution Approach 1:
The patent divides the image data into multiple regions and performs error detection on selected regions rather than the entire image. The error detection unit receives position information indicating specific error detection regions and only processes those areas, thereby reducing the volume of data subjected to error detection while maintaining reliable error detection coverage in critical areas.
Solution Approach 2:
The patent applies different error detection strategies to different regions of the image based on their importance. By specifying certain regions as error detection regions through position information, the system ensures high reliability in those areas while reducing processing load in less critical areas, achieving local optimization of error detection quality.
2Productivity
If error detection region is reduced to a portion of image, then processing load is reduced, but error detection coverage deteriorates
Solution Approach 1:
The patent enables dynamic selection of error detection regions through position information that can specify different regions for different frames. The error detection regions can be flexibly adjusted based on display content and requirements, allowing the system to adaptively balance processing load and error detection coverage rather than using a fixed region selection approach.
Solution Approach 2:
The patent implements error detection in a periodic manner across multiple frames by selectively applying error detection to different regions in different frames. This allows comprehensive error detection coverage over time while keeping the processing load manageable in each individual frame, as errors in different regions are detected across different frames.
3Adaptability or versatility
If position information for error detection regions is added to image data, then flexibility in error detection region setting is improved, but data transmission volume increases
Solution Approach 1:
The patent uses position information parameters (such as coordinates or region identifiers) to define error detection regions rather than transmitting complete region mask images. This parameter-based approach provides high flexibility in specifying error detection regions while keeping the additional data volume minimal, as position information requires far fewer bits than full-region representations.
