all though i am only starting, i am planning a port of a controller for this very LCD to work with Arduino. Collaborators are welcome.

Hope this helps. 

From Blob800 (above) reference you can find: http://www.hmangas.com/Electronica/Datasheets/LCD/EW32F50YLY.pdf

Although it's a different part number - it does correlate to the info listed below (from another source).

There is some Arduino info on this: http://arduino.cc/forum/index.php/topic,18353.0.html

Did you purchase the LCD screen part knowing if you could interface it with an arduino at all?

no, but i bought it because was cheap and worth a shot. i mean, only 2.50 for a 5 inch screen? i couldn't help it. if i cannot interface it with arduino, i will interface it with something else.

Sometimes things look too good to be true, a bargain is never a bargain. Unless you can find the datasheet for this, get the appropriate drivers, have the supporting electronics, know what kind of signals it takes, have the correct interface, you will have a very difficult time in trying to get it to work. It's still a DIY problem where everyone has the guts to a LCD screen scavenged from a laptop or cellphone but can't do anything with it. The stuff is pretty proprietary to the manufacturers of those devices unless it is sold as a standalone display for use with microprocessors or serial communications.

I have found the datasheet, and a way to use it with a pc paralell port. It looks ill be able to use it yet, arduino or not

Looks like we needed the same thing at the same time! I think this is it: https://docs.google.com/viewer?a=v&q=cache:vtr_7eoQ8DoJ:home.comcast.net/~hlandis0/photos/320x240%2520LCD%2520Display%2520instructions.doc+320x240+lcd+display.doc&hl=en&gl=us&pid=bl&srcid=ADGEESiqlsPHxVh3MsWwaTw5cSQ1ayv03kOpgU6wBqJNetaDyYUdsMcrRC5YcKdbfcahzgrWXSVHKPQJb6QPs7fvaTy4l287Icm7kYUIVqBV34c3N3uyBsX6HS9xpyHEK11Pm53gJS2G&sig=AHIEtbQvsgV6pntT7GFhaT03QOl_pG8qew

(still trying to figure it out myself)...
