Hello,
I have a project where I have to display values on a raw 7 Seg. "LCD" not LED. Basically its a 2000 count display, sort of like the ones in mulitmeters.
I went through this thread https://forum.arduino.cc/t/need-guidance-for-driving-single-digit-7-segment-lcds/376568/14 , but the circuit details are missing.
Can anyone share a circuit diagram if available ? Any other alternate simple low cost drivers spring to mind, please do let me know.
Cheers and TIA
There are Application Notes from Atmel (now Microchip) for driving LCD's with general purpose AVR I/O pins:
Simple (one common) LCD:
Multiplexed (multiple commons) LCD:

Thanks much !! Let me read through it.
You can find my source files for that LCD clock (including the Eagle PCB fab files) on my website at: Kevin Rye.net - Source
And the blog posts detailing the build is here if you're interested: LUMEX 3" 7-Segment Displays | Kevin Rye.net - Main
Hope that helps!

Thanks much @ryemac3 It will help a lot 
I am just in the early info gathering stage, will ping if more details needed.
Is it quite reliable in your experience ? I am building a hand held Voltmeter for field use, so your recommendation would be invaluable.
Cheers !
Good luck with the build. Not sure how much help I would be. I haven't touched an Arduino in almost 5 years. I'd probably have to go back and learn it all over again!

Its probably like riding a bike 
Just a quick question , since I have your attention. Why did you use an ATTiny to generate the phase pulses ? I mean is it not possible to do it from the ATMEGA 328 itself ?
Neat trick for switching the DP btw.
