I recentlly picked up a new $20 "reusable" digital camera with LCD display at a CVS drug store.

It comes apart easily and features a 1.5" color TFN-LCD 280x220, 18-bit RGB with LED backlight. A015AN02V1 mounted with 2 screws to PCB, and flex connector socket!

(Best version of datasheet I could locate that's readable)

You also get a NAND flash, SDRAM, photoflash subassembly, 1.3M (I think) CMOS image sensor, electomechanical lense cover among the various small discrete parts. And don't overlook the 2 AA Energizer batteries!

I later located this fine website analyzing this camera and the previous non-LCD version:

Fun stuff!

Is it possible to buy such a camera or similar anywhere in Europe?

I found another article about "hacking the LCD dispaly for your own projects" here: http://www.cexx.org/dakota/lcd.htm

Here's another version of the data sheet too: http://www.cexx.org/dakota/A015A...

Sweeeet! Defininately looks usable. I'll have to keep my eye out for one. Thanks for the tip.

280x220

The actual working resolution is 140 x 110, if I'm reading the datasheet correctly, because of the pattern of RGB pixels.

I'm not sure about availability in Europe. The company that makes these is called Pure Digital Technologies. They may point you to European sales outlets.

Here's their website :http://www.puredigitalinc.com/

As for resolution, I believe it truly is 280x220.

I tried the other (newer) rev of the datasheet, but it doesn't fully render in the several versions Adobe Acrobat I tied with it. The older datasheet displays perfectly. Oh, well....

Well, maybe it's not 140 x 110, but it's not 280 x 220. I suggest that we have 1/3 as many "real pixels" as you would think, since it takes 3 (one R, one G, and one B) to make a "usable" pixel. Maybe it's a terminology issue, but I know on the Sony display I used it was 240 x 160 "for real." But that was only 9 bit color, too.

Based on the triangular RGB pixel configuration, the displays effective resolution is 187 by 110.

Nice find though, I'll have to try and pick some up, next time I'm south of the border.

Writing code is like having sex.... make one little mistake, and you're supporting it for life.

Let's not overlook the CCD either! I'll bet you could come up with lots of fun ideas for that. At a minimum as a light/color meter

Thanks, I knew it was something like that :P

I tried cvs.com. No dice. :cry:

i picked up one of these a while ago and pulled it apart... the circuit necessary for driving the necessary voltage levels looked doable, but like a lot of work (although maybe i'm just feeling lazy...)

the ccd's -- unfortunately i wasn't able to find any data sheets... i got the feeling that if you were looking at high volumes, you could sign an NDA but otherwise they weren't super interested in giving hook-up info...
