Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color tracking methods fail to accurately normalize display effects across different display panels due to inconsistencies in measured display components, leading to offsets between target and actual grayscale color temperatures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional color tracking methods are used to measure display components, then color tracking can be performed, but measurement precision deteriorates due to inconsistencies between grayscale and monochromatic components
Solution Approach 1:
The patent applies preliminary action by pre-calculating modification values for monochromatic display components based on the difference between grayscale and monochromatic measurements. These modification values are stored and applied before final color tracking calculations, ensuring that the monochromatic components are adjusted to match the grayscale reference standard, thereby resolving the inconsistency issue before it affects measurement precision
Solution Approach 2:
The patent changes the parameters of monochromatic display components by applying calculated modification values to adjust their luminance, red, green, and blue components. This parameter adjustment ensures that the monochromatic components align with the grayscale components, resolving the reliability issue while maintaining measurement precision
2Manufacturing precision
If display settings are adjusted based on unmodified measured values, then color tracking process is simple, but manufacturing precision deteriorates due to offset between target and actual grayscale color temperatures
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing modification values for monochromatic display components before the actual color tracking process. This preliminary preparation eliminates the need for complex real-time calculations during color tracking, thereby improving manufacturing precision without significantly increasing device complexity
Solution Approach 2:
The patent introduces modification values as an intermediary element between the raw measured display components and the final color tracking settings. These modification values serve as a bridge that corrects the inconsistency between grayscale and monochromatic components, improving color temperature accuracy while keeping the overall process manageable
3Measurement precision
If monochromatic display components are used directly without modification, then ease of operation is maintained, but measurement precision deteriorates due to light leakage and panel characteristics
Solution Approach 1:
The patent applies self-service by enabling the color tracking system to automatically calculate and apply modification values to correct inconsistencies in monochromatic display components. The system self-corrects for light leakage and panel characteristics without requiring manual intervention, thereby improving measurement precision while maintaining ease of operation
Solution Approach 2:
The patent automatically changes the parameters of monochromatic display components by applying modification values that compensate for light leakage and panel characteristics. This automatic parameter adjustment improves display component consistency without adding operational complexity, as the process is handled by the system itself
