Display Data Adjustment for Color Shift Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices are unable to dynamically adjust display content to account for color shift influences, resulting in inconsistent image quality perceived by different human eyes.
Innovation Solution
A display data adjustment method that converts first grayscale values of sub-pixels from a first color gamut space to a second color gamut space, generates weight values, compares lookup tables to obtain high and low grayscale values, and selects these values to adjust the display data, thereby minimizing electrical low color shift (ELCS).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional display devices use fixed display content, then device complexity is low, but image quality consistency deteriorates due to color shift in side views
Solution Approach 1:
The patent applies dynamics by converting static display data into dynamic adjusted display data. The system dynamically adjusts display content based on viewing angle and color shift characteristics, transforming the fixed display mechanism into an adaptive one that maintains image quality consistency across different viewing conditions.
Solution Approach 2:
The patent changes parameters by adjusting grayscale values and color gamut spaces. It converts first grayscale values from a first color gamut space to a second color gamut space, modifying display parameters to compensate for color shift and improve image quality consistency without requiring hardware changes.
2Manufacturing precision
If display devices do not adjust for color shift, then ease of operation is high, but perception quality deteriorates due to graininess and color shift
Solution Approach 1:
The patent applies self-service by enabling the display system to automatically adjust its own display data. The system performs self-diagnosis and self-correction by detecting color shift characteristics and automatically generating adjusted display data, eliminating the need for manual intervention while improving perception quality.
Solution Approach 2:
The patent applies preliminary action by pre-processing display data before it is output. The system converts display data in advance from the first color gamut space to the second color gamut space, preparing adjusted display data that compensates for color shift effects before they occur during actual display.
3Manufacturing precision
If display devices use standard color gamut space, then compatibility is high, but color accuracy deteriorates in side views
Solution Approach 1:
The patent changes parameters by transitioning between different color gamut spaces. It converts color values from a first color gamut space to a second color gamut space, adapting the color representation to match the actual display characteristics and viewing conditions, thereby improving color accuracy while maintaining compatibility.
Solution Approach 2:
The patent applies universality by creating a multi-functional color space conversion system. The display device can operate in both the first color gamut space for compatibility and the second color gamut space for optimized color accuracy, making the system adaptable to different requirements and viewing conditions.

AI summary
A display data adjustment method is provided, including the following. First display data is received, and first grayscale values of first sub-pixels of different colors in the first display data are converted from a first color gamut space into color values in a second color gamut space. First weight values are generated according to the color values. Lookup tables are compared according to the first grayscale values of the first sub-pixels to obtain groups of first high grayscale values and first low grayscale values corresponding to the first sub-pixels. Second high grayscale values and second low grayscale values are obtained by calculation according to the groups of the first high grayscale values and the first low grayscale values and the first weight values. The second high grayscale values or the second low grayscale values are selected as second grayscale values of second sub-pixels in second display data.
