Responding to: ???'s previous message
Peak segment current to achieve an acceptable mean level for viewability?

Well, the duty cycle will stay the same - just wondering about a higher frequency.

It's currently about 400Hz; thinking about a few dozen kHz...

Don't want to go too high, or there'll be EMC issues, no doubt?

What kind of display is it?

Just a bog-standard, common-anode, 2-digit 8mm 7-Segment red LED.
