this, said 2160 Hz PWM dimming in it because that was true about the phone

the phone that actually changed it to 960 Hz.

These mirrors will actuate at about 6,000 Hz, and so we can turn light on and off very controllably, very selectively, and we designed resins

It also has 2160 Hz PWM dimming. So, it actually had 960 Hz PWM

But if you switch to a parallel setup, the Natural frequency increases to 6.4 Hz.

When the mechanism is in series, the natural frequency is 3.7 Hz.

And I put a frequency of 3.5 Hz, so it's close to the natural frequency of this system.

They updated to a much brighter, but more importantly, finally high-refresh-rate, 120 Hz display.
