Honestly, you'll get a whole lot more bang for your buck buying a used cell phone. Big screen, plays whatever media, power solution all inclusive. It could even play music. It'll even work to call 911 if one of your other projects burns down the house.
I love the idea of cell phone screens, however cell phones are not easy to come by here (to salvage for parts) and ordering online would be too much of a hustle, maybe theyll arrive not working, who knows...thanks for the idea though!
iSoda:
Can you send a video or a photo of it? As i want to make it as best as i can! Thanks!
No I have no video or photo.

ok, thank you for the help and sorry for the newbie and repeating questions... Ive decided to go with those displays as they have both I2C and SPI, should i take different ones? if so which?... thank you!
another question: Id like to check the option of displaying different 128x64 "videos" (10 pictures), given the low memory, i wont be able to do it. can I use an SD card shield and then store it over there? accessing it from the arduino? or is it too much of a hastle?
if it is not, which shield should I be using? of those
again - sorry for the repeating, newbie, annoying questions. thanks for taking the time and helping out,
With that display I would use the SPI interface and common up all the lines except the DS ( data select ). Each display needs it's own pin for the DS. Then the display who's DS line is low will be written to.
Yes you could store the image off an SD card if you want more predefined images.

ok thank you! I placed an order for those displays, which SD adapter should I take? each one has different pin number... 6 pins.. 9 pins... etc
which SD adapter should I take?
From a choice of what?
All SD adapters should use the same set of pins as the SPI bus. If the displays hanging off this bus are 5V devices then you need 3V3 level shifters between the SPI pins and your SD card which is 3V3.

I also ordered a voltage step down module just incase.

It is a signal level converter you need not a voltage step down converter.

Ok i changed it to those LLC, which SD card reader shouldI get? As some have 6 pins, some 9, and some more... here are my options
which SD card reader should I get
Quite honestly it doesn't matter they are all very much the same.
As some have 6 pins, some 9, and some more.
No. They all need the same number of connections to the Arduino. It just boils down to how you want to mount it on the Arduino.
Check back here with your proposed wiring before you power anything up.
