I am curious about the blur reduction features used in viewfinders (cameras) and VR headset display panels.
For instance I had several question after watching a youtube video titled "Nikon Z6 III Viewfinder Refresh Rate Measured".
- Is the horizontal black band related to some kind of rolling black frame insertion in view of motion blur reduction ? I found that sony microOled displays often use 0.9 duty cycle which might be the case here.
- How is this different from PWM on a smartphone ? Is it less eye straining ? (few infos online on that matter and might be the topic for another forum)
