How does a graphic display lcd work?

Apr 21, 2007 5 Replies

Hi,



I bought a graphic lcd (Powertip PG320240c) and I'm searching a document that explains how the display works; in fact the lcd hasn't a controller and I want to implent it with a DSP. Now the display has these inputs:



-FLM



-M



-CL1



-CL2



-D-OFF



-DB0-DB3



How can I control the lcd?



Thanks,



Mauro


Aannndd the very first result that pops up when you enter 'PG320240c' into google is... a datasheet

I can point you to where I explained this before in case you're still having trouble. Don't know if there's a better way of directing you there (Apologies for being a bit of a newb) but here's the link to another discussion...

Otherwise, search for PolyVinalDistillate here - you'll find it :) Good luck. Nick.

Hmm... I attempted to post this morning, but apparently I failed miserably! I've posted before to explain the functions of the pins on a GRX LCD panel (at least the functions I'm used to on my mono panels!)

The link to that thread is here:

You're looking at the 4th posting.

If you want me to help further, I'll check this out from time to time :) Nick.

I've read the thread and I don't understand how to use the M input. I've looked the datasheets of common/segment driver (LC79401 and LC79430); it calls M "LCD drive output alternation signal" but doesn't explain how to use.

Thanks!
