Display Brightness Compensation Model Tuning for Panel Aging Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels exhibit varying life attenuation values across different areas, leading to inconsistent brightness due to over- or under-compensation using fixed preset models, which fail to accurately account for individual panel differences.
Innovation Solution
A model adjustment apparatus and method that allows users to adjust compensation values based on user input, refining the preset model to match the specific life attenuation values of different areas within a display panel, thereby ensuring accurate brightness compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a preset fixed model is used for brightness compensation, then the compensation process is simple, but the compensation accuracy is poor due to discrete differences between display panels
Solution Approach 1:
The patent applies parameter changes by adjusting the compensation parameters based on the actual life attenuation values detected from different areas of the display panel. Instead of using fixed preset parameters, the system dynamically modifies the compensation parameters to match the specific characteristics of each panel, thereby resolving the contradiction between simple compensation process and accurate compensation results.
2Device complexity
If a preset fixed model is used for brightness compensation, then the model structure is simple, but the adaptability to different display panels is poor
Solution Approach 1:
The system maintains a relatively simple model structure while improving adaptability by changing the compensation parameters based on detected life attenuation values. This allows the same model structure to adapt to different display panels with varying characteristics, resolving the contradiction between model simplicity and adaptability.
Solution Approach 2:
The patent implements feedback by detecting the actual life attenuation values from different areas of the display panel and using this information to adjust the compensation parameters. This closed-loop feedback mechanism enables the model to adapt to different panels without requiring complex model structures for each individual panel.
3Ease of operation
If brightness compensation is performed without adjusting for individual panel differences, then the operation is simple, but the display quality consistency is poor
Solution Approach 1:
The system maintains ease of operation by automatically detecting life attenuation values and adjusting compensation parameters without requiring manual intervention. The feedback mechanism ensures that each panel receives customized compensation based on its actual characteristics, thereby improving display quality consistency while keeping the operation simple.
