Graphical LCD - Which one have you used in the past?

[seidleroni]

I am about to start a project using a graphical monochrome LCD and I wanted to know if anybody here has used any graphical LCD and what their thoughts were about the ones they used (how easy was it to program, how good did it look, etc...). If you recommend any to me (specifically smaller displays approximately 1" to 2" diagonal) would be great!

Is this for production or for a single hobbyist project ?

For production we have bought units from Densitron:

For a "one off" project, Crystalfontz makes a good product:

If it is for a one-time / hobby project than you could use a mobile telephone display. I wouldn't recommend these for large production series as you never can be sure the display will be on sale next year.

Many phone display projects can be found on the internet. For example the Nokia 3310 has a 84x48 pixel monochrome LCD for about US$10.

My favourite is the Nokia 6100 132x132 pixel color LCD, often used in hobby projects and lots of documentation can be found. It is available at various internet sources for US$20 or less, for example at eBay and Sparkfun.
Two good introduction documents for programming this display:

The Sparkfun site has more links to documents and code examples, even a link to CCS-style code for the PIC16.

Just to answer your questions, this is for a production system, not a hobbyist system. One of the displays we're considering is using an OLED display like this: http://www.osddisplays.com/oled.php specifically the one that has the OSD display logo in yellow on black.

Also, it seems that most of the displays make it kind of difficult to display text as you have to map what each character looks like. I know there is the example (GLCD.c) provided by CCS, but is that example useable on most graphical LCD's or is it only specifically for one type?
