Abstract

Examples relate to display systems and techniques for reducing visual artifacts in field sequential color displays. A system includes a field sequential color display device that presents visual content according to a first display configuration, and an eye tracking subsystem that detects rapid eye movements. The system predicts a duration of a detected rapid eye movement and temporarily modifies display parameters during the predicted duration according to a second display configuration that reduces color breakup artifacts. The second configuration can include reducing content opacity through optical filter control, adjusting display brightness or contrast, or modifying color data at region boundaries to use monochromatic colors. After the predicted duration, the system returns to presenting content according to the first display configuration. The prediction of movement duration utilizes relationships between peak velocity and acceleration profiles of eye movements to overcome eye tracking and display latency constraints.

1 . A system, comprising:

at least one processor; and

a memory storing instructions that, when executed by the at least one processor, configure the system to perform operations comprising:

presenting visual content to an eye via a field sequential color (FSC) display device according to a first display configuration in which the visual content is displayed as a temporal sequence of monochromatic color images;

detecting a rapid eye movement of the eye;

predicting a duration of the rapid eye movement;

presenting the visual content via the FSC display device during the predicted duration of the rapid eye movement according to a second display configuration, the second display configuration being configured to reduce a motion artifact during eye movement by modifying a first region of the visual content to display a monochromatic color in a border portion of the first region bordering a second region of the visual content; and

after the predicted duration of the rapid eye movement, presenting the visual content via the FSC display device according to the first display configuration.

the motion artifact comprises color break up.

3 . The system of claim 1 , wherein:

the second display configuration comprises reducing an opacity of the visual content.

4 . The system of claim 3 , wherein:

the FSC display device is at least partially transparent, such that the eye can see a real-world visual field through the display;

the FSC display device comprises an optical filter interposed between the visual content and the real-world visual field, the optical filter being controllable by the system to adjust an opacity of the optical filter; and

the reducing of the opacity of the visual content comprises reducing the opacity of the optical filter.

5 . The system of claim 1 , wherein:

the second display configuration comprises reducing a brightness of the visual content.

6 . The system of claim 1 , wherein:
