anyone made this into a pico projector? basically need to know if the screen can be separated from the backlight without damage.

Not really. Physically, yes it emits and you can image the emitting surface onto a wall/screen. You lose intensity as the magnification increases - if you project the screen to be 10x the size of the display it will be 10x dimmer and have lower contrast.

Does this display give you the option to pick blue or yellow pixles threwout the display or is just the top portion yellow and the rest blue?

Pixel values are either 1 or 0. The screen is made up of 8 rows of "pages" that are each 8 pixels high, giving a total of 64 rows of pixels. The easy to use Adafruit library for Arduino hides these details from you. There are 2 sections of pages on the screen. The top section contains 2 pages of yellow (value 1) or black (value 0). The bottom section contains pages 6 pages that are blue (value 1) or black (value 0). There is a black horizontal line that separates the top 2 pages from the 6 bottom pages. The screen is essentially 2 separate LED panels. This is useful if its desired to have 2 separate screens. If not, they do make other versions of this screen that are 1 single color which are 1 complete panel without the separation. For my purposes it's great to have the separation.

new to arduino.. will this work with the uno

It should work with any Arduino or variant like the Teensy that has SCL and SDA pins. Look at the pinout. The Uno and Nano even use the same chip, the 328P. I just connected mine to a Teensy 3.0. I found that even though on the display it says the address is 0x78, I had to leave the default address of 0x3C in the example program I tried it with.
