I was wondering if it would be possible to take the LED lights in something like an edge lit backlight using mini or micro LEDs, and mirror the engineering of how the virtual boy display works. You could pulse these LEDs at insanely high brightness for brief periods, they strike a spinning mirror to not only mimic a raster scan like the virtual boy, but to make a monochrome image that you process with software that would serve as a light map behind the LCD, and is low persistence at the same time due to the mechanics of the system.

Use something like the chief's software phosphor fade simulation to sync the raster scanning light map to LCD scannout. It might not be perfect CRT motion, but it would be damn close as would contrast ratio due to the mechanical nature of the system.

You could probably even use a laser phosphor light source for much higher brightness pulses and longevity. 1 line at 20,000+ nits hitting the mirror in a more manageable power envelope.

Why would we want to mimic the virtual boy's display? Because 1 vertical strand that was only 1x224 LEDs made for a monochrome 384x224 extremely low persistence rasterized image in the virtual boy.

Imagine a 1x1920 line of LEDs or 1x7680, with brighter light source scanned to make a monochrome image. IE a modern equivalent of the system from virtual boy.

Imagine using similar engineering to get a monochrome 720p image in a backlight that could serve as a light map for insane local dimming, but it is also doing insanely low persistence blur reduction due to how it physically works.

My idea is that we mimic the engineering of how that system worked to make a mini or micro LED backlight that is cheap, but also serves as an LED light map. Mimicking function that the old DLP projector played in DIY perks' video, but much brighter and more practical to achieve the same goals.

This probably makes zero sense, but hopefully when you watch the videos, you would get the gist of what I am trying to say.
