Most cheap character displays are built to work at 5V, and this can be a problem if your circuit is designed around lower voltages. Here are some reasonably priced 3.3volt displays that range from 1X8 to 3×16 displayed characters.
You can interface with them over three protocols: 8bit, 4bit, and SPI. The displays are sold without a backlight, but stackable LED backlight modules are sold as well.

I’ve used this series before, they are really thin
There’s no reason to use 5V in any projects anymore anyways
There will be always a reason to use 5V. When you start the project from scratch, there is no problem, but when you patch an existing design or add specific circuit to existing electronics, or when the costumer impose design rules, you cannot force things to go 3.3v !!
These LCDs are really cool. They are thinner, high contrast and low power displays supporting multiple types of interfaces. They are based on ST7036 controller/driver chip which provides a software command for contrast adjustment. I once reviewed AmiPIC18 LCD shield from Geno Electronics that uses a similar LCD, and I love it. Here’s the link to my reviews:

I’ve just designed these into my next two projects ! I still have to use a lot of 5 V parts though because I’m interfacing with older sensors and what not. But these panels seem pretty groovy, can’t wait to fire them up. I like the easy mounting as a dip chip
hey,do you have a blog or something where you write about your projects and stuff?
These do indeed look sweet. Anyone notice the catalog page mentions full RGB backlight? They don’t seem to have it for purchase though. I think that would look killer with the black background, and user selectable color.
Only problem for me is they look fairly small… .5″ X 2″ ?
there are quite a few sizes and different back light options. RGB might not be on all the modules?

nice of them to provide the eagle files too.
I agree that they are small. I’m looking for display with more space, like the 3×16 or even 4×20 and find these small.
It looks to me like they are all of the same size, with bigger or smaller characters, depending on the layout.
Looks like the same things from MMSE, with many other display types as well. The ones from MMSE mention that they can run on 5V as well.
The DOGS graphical LCDs are pretty nice too. 102×64 and very thin. TI also has a full HAL for the DOGS LCDs on MSP430 devices.
