Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices experience changes in pixel characteristics over time, leading to image deterioration, which existing systems struggle to accurately detect and compensate for.
Innovation Solution
An optical compensation system that includes an electronic device with a deterioration optical compensator, which divides the device into normal and deterioration areas, generates compensation values for each area, and combines them to create a final compensation map for correcting image deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing compensation systems are used, then device complexity is reduced, but measurement precision of pixel deterioration is insufficient
Solution Approach 1:
The patent segments the display panel into multiple regions (first region, second region, third region) with different deterioration characteristics. By dividing the panel into distinct zones and applying region-specific compensation values, the system achieves higher measurement precision for pixel deterioration without requiring a complete redesign of the compensation architecture, thus managing device complexity effectively.
Solution Approach 2:
The patent applies compensation values selectively to different regions rather than uniformly across the entire panel. By focusing compensation efforts on specific deteriorated areas (particularly the second region with significant deterioration) while using different strategies for other regions, the system achieves precise deterioration measurement without the complexity of comprehensive pixel-level compensation across the whole display.
2Manufacturing precision
If uniform compensation is applied across the entire display panel, then device complexity is reduced, but manufacturing precision of image quality is insufficient
Solution Approach 1:
The patent implements local quality by assigning different compensation values to different regions of the display panel based on their specific deterioration characteristics. The first region receives compensation values tailored to its mild deterioration, the second region (with significant deterioration) receives enhanced compensation, and the third region receives appropriate compensation for its characteristics. This region-specific approach ensures high image quality consistency without requiring overly complex global compensation mechanisms.
3Manufacturing precision
If region-specific compensation is implemented, then image quality consistency is improved, but ease of operation deteriorates
Solution Approach 1:
The patent performs preliminary action by pre-calculating and storing compensation values for each region before actual display operation. The compensation values for the first, second, and third regions are determined in advance based on their deterioration characteristics, allowing the system to apply pre-determined compensation without requiring complex real-time calculations during operation, thus maintaining ease of operation while achieving high image quality consistency.
4Reliability
If simple compensation methods are used, then ease of operation is maintained, but reliability of deterioration compensation deteriorates
Solution Approach 1:
The patent implements dynamics by creating a multi-layer compensation system that can adapt to different deterioration levels in different regions. The system dynamically selects appropriate compensation strategies for each region (first region with mild deterioration, second region with significant deterioration, third region with specific characteristics) rather than using a static uniform approach, thereby improving reliability without requiring excessive system complexity.

AI summary
Disclosed is an optical compensation system including an electronic device including a plurality of pixels and displaying an image corresponding to an input image signal, an image capture device that captures the image displayed on the electronic device and provides a captured image signal, and a deterioration optical compensator that outputs a correction data signal, which is obtained by correcting the captured image signal based on an accumulation data signal from accumulating the input image signal, and outputs a final compensation map for compensating for deterioration of the electronic device based on the correction data signal. The electronic device displays the image corresponding to the input image signal by performing a deterioration compensation operation based on the final compensation map.
