Re: AW: [avr-chat] LCD duty cycles, help please

[Stephen Wong]

Oh, you're right, you've a no-controller type LCD, so, 
you've to scan the LCD at the timing specified exactly.  I 
imagine, there should be some 'controller' (but not an 
ATmega) to drive such thing.

The negative voltage VLCD (as specified as VDD-28) is DC, to 
be used to drive each LCD pixel to give good contrast.  The 
duty cycle is roughly how frequent each pixel has to be 
scanned / refreshed.
