Display Color Temperature Curves for Flicker-Free Low-Frame-Rate Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing color temperature adjustment methods in display technology rely on linear interpolation, which requires high frame rates to avoid flickering, limiting their applicability and display quality.
Innovation Solution
A method involving the definition of at least three reference color temperature points to partition ranges, with intermediate points selected using a predetermined algorithm, allowing for a pre-fitted color temperature curve that enables smooth transitions without flickering, even at lower frame rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If linear interpolation is used for color temperature adjustment, then the adjustment method is simple, but high frame rates are required to avoid flickering
Solution Approach 1:
The patent pre-calculates and stores color temperature data for multiple reference color temperature points before actual color temperature adjustment is needed. This preliminary preparation creates a lookup table that enables smooth color temperature transitions without requiring high frame rates during actual operation, thus resolving the contradiction between simplicity and frame rate requirements
Solution Approach 2:
The patent divides the color temperature adjustment range into multiple segments by selecting reference color temperature points (e.g., 2000K, 4000K, 6500K, 9000K). Each segment between reference points is handled independently with pre-calculated data, allowing the system to achieve smooth transitions without requiring uniformly high frame rates across the entire range
2Ease of manufacture
If linear interpolation is used for color temperature adjustment, then the implementation is straightforward, but flickering occurs in the displayed image
Solution Approach 1:
The system pre-calculates color temperature data for reference points and stores them in advance. During actual color temperature adjustment, the system retrieves pre-calculated data rather than computing it in real-time, which eliminates calculation delays and ensures smooth transitions without flickering while maintaining implementation simplicity
Solution Approach 2:
The patent changes the approach from real-time linear interpolation to using pre-calculated color temperature data at specific reference points. By transforming the problem from continuous calculation to discrete data retrieval and interpolation between stored values, the system achieves both simplicity and reliability
