Family member got a new microwave. The LED panel hurt my eyes. I took some slow-mo footage. It clearly shows a flicker. I am guessing this is an OLED flicker?
Yes it is, probably they are using a cheaper display with a lower refresh rate.
Good that it's easier for you to avoid locking your gaze on it if you don't live there.
Appliance LED's are a nightmare for me to. Thank goodness I was able to find a new washing machine with all analog dials
You won't like the Ecobee thermostat I have. I have the screen set to turn off because the refresh rate is really low. Maybe because it's running off furnace power which is 24V or something.
