PWM is noticeable on most 7-segment displays (on microwaves etc).
Clicking your teeth together makes it pretty apparent usually, the segments will appear to jump around. Try it at home!

- kw71 8y agoThis is not that. This is multiplexing and the purpose of it is to save i/o wires. If you film it with a high speed camera you will see something like one digit being lit at a time.
- fenwick67 8y agoYeah you're right, calling it PWM isn't really correct.
