Design Considerations Between Color Gamut and Brightness for Multi-Primary Color Displays

Nowadays, displays are ubiquitous in our daily lives. Long-time exposure to a display’s unnatural light could influence the user’s circadian rhythm, especially at night. Here, we propose a four-color micro-light-emitting diode (LED) display to achieve low circadian action for nighttime uses. Specifically, we evaluate the RGBW-type (red, green, blue, and white) and RYGB-type (red, yellow, green, and blue) micro-LED displays in terms of circadian effect and color gamut coverage. With the addition of an extra white subpixel, it was found that the circadian effect at night can be reduced dramatically, but the color gamut remains unchanged. However, with an additional yellow subpixel, both the circadian effect and color gamut were found to improve. Finally, we simulated the circadian illuminance of real image contents for different displays. In comparison with existing liquid crystal displays, organic LED displays, and RGB (red, green, blue) micro-LED displays, the proposed four-primary-color micro-LED displays can significantly reduce the circadian effect at night.

Color Displays

The U.S. Marine Corps has proposed sensor and display improvements to provide night attack capability for the AV-8B and F/A–18 aircraft. The aircraft enhancements include the addition of a Forward Looking Infrared sensor displayed on a new raster Head-Up Display, Night Vision Goggle compatibility, and a color multi-purpose display. A human factors engineering analysis was performed to identify the human factors impact of the cockpit changes involved. Included in the analysis were a literature review, interviews with pilots, design considerations review, and development of recommendations based on both human factors standards and lessons learned from similar projects. The primary areas researched were: cockpit lighting, color displays, and night vision sensor utilization.
