I've found a quite interesting application note from Freescale 
(www.freescale.com) about using OLED displays (AN3415.pdf for the files 
AN3415SW.zip). To find the Application Note in Freescale site, click in 
Documentation under "Get Support" (right-side) the application note. 
Sort in descending order by date, it's a quite new AN dated 3/8/2007.

It talks about "OLED Driver Demonstration for 4 bits per pixel Displays" 
but as I've already learned, that in fact it converts windows bitmap 
fonts in a 1 bit deep and the 4-bit part uses the brightness settings 
(Thanks for the explanation Scott).

Anyway it could interest anyone that wants to learn a little bit more 
about these LCDs.

Regards

 

Hans
