I just love that sparkly background liquid-crystal displays have! A camera flash brings it right out, too.
I've long wanted to learn how to use graphic LCD modules. They're fairly cheap liquid-crystal displays designed to be used in a variety of devices, and it's very likely you've seen some of them just like this one used in equipment around town. For you other Salt Lakers out there, I'm pretty sure the gas pumps at the Costco on 3rd West and about 17th South use displays like the one pictured here.
Your laptop screen or desktop flat-panel is the great-great-great-etc. grandchild of the generation of displays this one belongs to. The heart of this one is a chip called the Toshiba T6963C and I think it was designed in the 1980s. Though this individual display was built in about 1998, it has a very 1980s feel to it - very slow drawing and capable only of black and white. T6963C-based displays can show some simple clunky pictures - I think you're required to make them display Tux the Linux Penguin at least once or they take away your geek ID card.
For me, these displays were demystified by the T6963C Rosetta Stone by Steve Lawther. Mr. Lawther, a helpful British guy - sorry, bloke, designed a straightforward test circuit for these displays around ten years ago. I get the sense that many if not most electronics hobbyists who have used displays based on the chip have started from his design. The test circuit is based on an obsolete MCU, so I ported his code for a newer chip and (as they say across the pond) Bob's your uncle.
His test code didn't include a checkerboard screen like this - that was my own contribution, because I like checkerboards.
I'm not sure what I want to use these displays for just yet, but I dig knowing that I can in fact get them to work.
About ten very expensive looking LCD TV's have been installed on the roof at a shopping centre I went to recently. They're not playing anything yet and no one else seemed to look up and notice they were there. Probably going to be used for advertising or other store related information.
It would be cool if they were in a food court and played foxtel.
When we built the addition on to our home several years ago, we had this "space" above the fireplace for a 36 inch CRT television. Of course with the change in technology, we had to change the space. The hardest part was moving the old 225 pound TV out. Miserable. After that, I framed in the area based upon the dimensions of a Samsung LCD TV we picked up on clearance at Best Buy. I also added an in-wall center channel speaker to go with the pre-existing left/right in-wall speakers. The TV was left partly recessed because I am not sure if the radiant heat from the rarely used fireplace will cause any problems. Some finishing dry wall work and Zoe's excellent paint job and ta da!

I found this RadioShack perfboard and bought the header pins. The right-angle header socket I already had handy, although in the end I used a strip of 16. Note the bulge in the middle of the pins. This is the part I wanted to press against the LCD pin hole.
After seeing the crazy price SparkFun was charging for these, I had to get one.
I picked up a complete set - large screen, small screen and frame with backlights. They stick together easily.
I'm still dreading the prospect of somehow connecting up to them - the small screen especially has 0.4mm wide copper contracts, 33 of them! that's crazy. I've ordered some of the very thin wire used for modding games consoles (kylar insulated 30AWG stuff) and will attempt that later.
Even once they're connected, there's the massive issue of figuring out how to write data to them.
One easy part to get working was the backlight. This is a seperate connector with seven pins - one anode and six cathodes, one per LED. I connected wires up to each pin and put them through some heatshrink to 0.1" crimp headers and have connected them to 2 AA batteries temporerily. The backlight looks pretty snazzy, so I can't wait to get some actual display on these!

Not finished yet, I'll probably veneer those burnt mdf edges when I get a chance. It's For an Arduino + ethernet shield rss reader i'm making.
Very much inspired by spikenzie.
Awesome 19" LCD monitor - 1280x1024 under ProView brand. Purchased at MicroCenter store for $299 after $60 rebate. Good deal!
This was our first working system. Laser based, mono colored LCD, infrared, RF Modules, and basic software.
saying hello.
the backpack module fits exactly behind the lcd board (same form factor) and so it frees up a LOT of internal space inside chassis for other things.
LCD arm from Ergo In Demand (25-KCB-110B). I can position the monitor in my sight line no matter how I'm reclined and it doesn't interfere with the sound system.
The speakers are Gallo Reference 3s driven by a Bolder Cable modded Squeezebox 2 into a Modwright SWL 9.0 SE preamp feeding an EA modded Carver ZR1600 amplifier (plus the Gallo bass amp).
