I was reading an article on the new LG display with a refresh rate of 7680Hz and it says:
While a typical refresh rate for a monitor might be 60Hz-240Hz, an outdoor display designed to be viewed from a distance needs to be much higher
The idea that there’s an intrinsic link between refresh rate and viewing distance is new to me and feels unintuitive. I can understand the need for high brighteness for far view distance. I also could understand refresh rate mattering for a non-persistent (CRT) display. But for an Led display surely you can see it far away even if it refreshes once a second?
Refresh rate normally needs to be high enough to avoid pixels “jumping” between refreshes on high resolution displays, so wouldn’t higher view distances allow you to decrease the refresh rate?
Is the article just spouting bullshit? Or is there an actual link between refresh rate and view distance?
Available in a range of interchangeable 10mm pixel pitch panel variants to suit – 120(W) x 120(H), 120 x 90 and 90 x 90 – the Philips Urban LED 6000 Series will deliver unparalleled high contrast (5000:1) and high refresh rates of 7680hz for smooth broadcasting – including live coverage on matchday – with more colour subtlety, shading, and saturated colours.
(so sports broadcast tv cameras dont catch flicker.)
Do sports broadcast cameras operate at over 3840 fps?
its very overkill, yes. beyond future-proof. this is for stadiums and major venues and expect to be around for many years.
