This is exactly what I expect from your channel. A way to learn electronics, combined with your experience, not seen in any other channel. A bit of stuff for the beginner, a bit of new stuff for the experiences. Great subject!

This big single digit LCD (or a similar one) was used in a clock circuit published in one of these electronic paper magazines. I think it was elektor. It was 10+ years ago. Point is: Since they are static they just used 74HC595 or 4094 (can't remember exactly) to drive all the segments. The common pins were tied together and driven by something else. The microcontroller had to do the AC switching of course. The display is so big that it was no problem to hide the DIL ICs underneath it.

My mom had a 16 segment display on a Hifi and I always sat in front of it watching the text scroll. Amazed.

It's actually possible to drive the through-hole type (the simplest) LCDs using GPIO output pins by reversing the drive polarity in a loop (I used a 4Hz timer). I used a TI MSP430F2272 micro-controller that had all the required GPIOs.

i've always enjoyed these segment LCDs<br><b>sharp</b> digits and incredible contrast (when at the right angle of course)

lol I came here because of application note AN658 and now he's pointing me back over there!

This just took a lot of mystique out of the world, but it is very cool to see that simplicity was always there.
