I need a screen (LCD I assume) that I can program to display large numbers & letters for my audio project. All I will display is:

Vol: 0 to 100
Source: 1 to 4 or Possibly, CD, SQT, IPOD, PHONO

The sort of text size I am thinking say for the volume numbers& source selection is say 15 to 20mm (5/8 to 7/8")

I would like a bit of extra space on the screen maybe to put the sample rate etc but this could be small

It would probably look something like this:

Vol: 100
Source: PHONO
Sample Rate: 24bit 96Hz

Can anyone recommend a screen that would be good (ideal) for this application?

How do you edit posts?

I didn't get the text in the proper proportions :)

Never mind I found it.

I rather like the 2.2" TFT LCD from Adafruit:
http://www.adafruit.com/products/797

It uses SPI so you don't need too many pins, there are libraries and tutorials for it, and you can do different text sizes and colours easily.

I've used it in a thermostat: http://planetstephanie.net/2012/05/09/thermostat-three/

What about OLEDs? I have this one: http://www.newhavendisplay.com/nhd2712864ucy3-p-3621.html
It has a really good contrast.

It is also supported by u8glib (http://code.google.com/p/u8glib/), which has big and small fonts as part of the distribution:

Font list for u8glib is here: http://code.google.com/p/u8glib/wiki/fontsize

Thank you for your input, I will do some reading.

Any other suggestions anybody.

I have the same issue.  I'm actually considering using an old Apple iPod Touch, then serving the pages up with an arduino+Ethernet shield to the iPod via Wi-Fi.

The 4D OLEDs are pretty nice and might suit your project.
I've been using the 0.96" 96x64 display, but there are a couple larger ones.

There are a couple libraries on this forum (including one I've been writing) that can interface with them.
