Eye-Movement-Aware Display Image Compensation for Color Break-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The color sequential method in LCD displays results in a color break-up phenomenon due to eye movement, affecting the user's viewing experience.
Innovation Solution
A display image compensation method that monitors eye movement behavior to identify compensation areas where color break-up occurs, determines current and deviation color values, and adjusts image colors using compensation parameters to mitigate the color break-up effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the color sequential method is used to eliminate color filters, then light transmittance is improved and power consumption is reduced, but a color break-up phenomenon occurs during eye movement
Solution Approach 1:
The patent applies preliminary action by predicting the user's eye movement trajectory in advance and pre-compensating the display image before it is shown. The system calculates where the user's eyes will move and adjusts the colors in those future positions to prevent color break-up from occurring in the first place
Solution Approach 2:
The patent changes the color parameters of display pixels based on predicted eye movement. By dynamically adjusting color values (RGB parameters) in regions where color break-up is expected to occur, the system compensates for the visual artifact while maintaining the benefits of the color sequential method
2Illumination intensity
If the color sequential method flashes R, G and B frames sequentially, then RGB three-color displaying is realized with improved light transmittance, but color accuracy deteriorates due to eye movement causing non-overlapping positions on retina
Solution Approach 1:
The system performs preliminary compensation by calculating the expected eye movement and adjusting color values in advance. This ensures that even though the R, G, and B frames are displayed sequentially at different positions on the retina, the final perceived color remains accurate
Solution Approach 2:
The patent uses eye movement tracking feedback to dynamically adjust the display image. By monitoring actual or predicted eye position and using this information to modify subsequent frame colors, the system maintains color accuracy despite the sequential flashing method

AI summary
The present disclosure provides a display image compensation method, a display and a storage medium. The display image compensation method includes: when an eye movement behavior of a target subject is monitored, determining a compensation area in a display image based on the eye movement behavior, the compensation area being an area where a color break up phenomenon occurs in the display image during watching of the target subject due to the eye movement behavior; acquiring a current display color value of the compensation area, and determining first difference information between the current display color value and a deviation color value of the compensation area; and determining a color compensation parameter based on the first difference information, and adjusting an image color of the compensation area in the display image according to the color compensation parameter.
