Field Sequential Display Color Separation Inhibition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Field sequential display devices experience color separation due to the rotation of the eyeball, causing RGB components of an image to fall at different positions on the retina, leading to a perceived color separation phenomenon, which is a challenge in VR applications where immersive experiences require reduced color and brightness differences between frames.
Innovation Solution
The method involves splitting an original image into multiple frames with specific backlight and pixel data determination to ensure that all colors are lit up during one frame and only one color during subsequent frames, using a cyclic sequence to minimize perception differences and inhibit color separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If field sequential display devices use sequential scanning of RGB sub-frames to achieve color display, then color display capability is improved, but color separation phenomenon occurs due to eyeball rotation causing RGB components to fall at different positions on the retina
Solution Approach 1:
The original image is segmented into multiple sub-frames (first sub-frames for each color channel and a second sub-frame), and the backlight is segmented to display different colors in different time periods. This temporal segmentation allows each sub-frame to be displayed with its corresponding backlight color, reducing color separation while maintaining color display capability
Solution Approach 2:
The display system uses periodic action by cyclically switching between different backlight colors (red, green, blue) and corresponding sub-frames in a predetermined sequence. This periodic synchronization ensures that each color component is displayed with its appropriate backlight, reducing the color separation phenomenon caused by eyeball rotation
2Adaptability or versatility
If VR applications require reduced color and brightness differences between frames to maintain immersive experience, then user immersion is improved, but display complexity increases due to need for precise backlight and pixel data coordination
Solution Approach 1:
The patent merges the control of backlight data and pixel data into a unified display method where both are determined together based on the original image. This coordinated approach ensures that color and brightness differences between frames are minimized, maintaining immersive experience while managing complexity through integrated control
Solution Approach 2:
The system dynamically changes parameters including backlight brightness, color composition, and pixel values across different sub-frames according to the original image data. By adjusting these parameters in a coordinated manner, the display maintains consistent color representation and minimizes frame-to-frame variations, enhancing immersion while adapting to different content requirements

AI summary
A display method for inhibiting color separation, including: acquiring an original image to be displayed, and determining a plurality of frames of sub-images each having a single channel according to the original image; determining backlight data and pixel data of each of the plurality of frames of sub-images; sequentially displaying at least part of sub-images in the plurality of frames of sub-images, in a preset sequence, according to the backlight data and the pixel data of respective frames of sub-images, where the backlight data of any one frame of displayed sub-image serves to light up all colors contained in the backlight assembly, and the backlight data of the sub-images except the any one frame of displayed sub-image serves to light up each time one color contained in the backlight assembly.
