Your welcome. It’s one of those things that I think people should know about and it’s a damn shame that so many companies put out products that use PWM without even thinking about the effects it could have on people. Especially in the age of LED’s we live in, it’s the primary method for dimming them, which is rather unfortunate. OLEDs don’t seem to use PWM as far as I know so the next generation of screens should be better, and some LED’s don’t use PWM flickering which makes that website a useful resource to have.
