Extra dot on seven-segment display?
« on: May 23, 2020, 06:58:39 pm »
I have a few Lite-on LTC-4727JR seven-segment displays with four digits, four decimal points, a colon and a mysterious extra dot (marked L3 in the data sheet). Anyone know what the extra dot is for?

Degrees most likely :)
Ever noticed the circle next to C and F?

Agree, it’s degrees. It’s a multi-purpose clock display. Bog standard stuff.

This used to be done by putting the rightmost display upside down.
