Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple linear mixture model is used for crosstalk correction, then the device complexity is reduced, but the crosstalk suppression precision deteriorates

Engineering Contradiction:

Improvemodel complexityVSAvoidcrosstalk suppression precision

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent changes the parameters of the crosstalk model from a simple linear mixture model to a comprehensive model that includes multiple deterioration characteristics (gradation characteristics, mixing characteristics, and other display-specific parameters). This allows the model to accurately represent the actual crosstalk behavior of different display devices while maintaining manageable complexity through systematic parameter organization.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces a dynamic approach where the crosstalk model parameters are not fixed but are determined through measurement and calculation specific to each display device. The system adapts the model parameters based on the actual display characteristics, making the correction process dynamically optimized for each device rather than using a static simple model.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a simple linear mixture model is used for crosstalk correction, then the calculation process is simplified, but the correction accuracy deteriorates

Engineering Contradiction:

Improvecalculation process simplicityVSAvoidcrosstalk correction accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent segments the crosstalk correction process into distinct stages: measurement pattern generation, characteristic measurement, parameter calculation, and correction application. This segmentation makes the complex calculation process more manageable and systematic, allowing each stage to be optimized independently while maintaining overall accuracy.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary measurements and calculations to determine the specific crosstalk parameters for each display device before applying the correction. By pre-characterizing the display device through measurement patterns and calculating device-specific parameters in advance, the actual correction process becomes simpler while maintaining high accuracy based on the pre-determined parameters.
