Not possible without an interface board to convert to something the RPi can use such as HDMI or composite.
The interface board, if one exists, will be as large as the RPi and probably cost more than the RPi itself.
Search ebay with the model number of the screen to see if something exists.
Here is an example of typical screen and interface board: http://www.ebay.com/itm/HDMI-VGA-Contro ... 2edc886a90
Unless specified otherwise my response is based on the latest and fully updated Raspbian Buster w/ Desktop OS.

A 40-pin FPC interface with those two lines cut and lots of parallel data lines on the driver board? You might be lucky and have a DPI screen, which you can get to work with the same interface used for Gert's VGA adapter. If you are lucky, the pinout is close to the screens sold by Adafruit, which means it might work with their DPI Kippah (http://www.adafruit.com/search?q=kippah&b=1) in 18-bit color. For full 24-bit color, you have to hack together a solution yourself, though, with lots of material found in the B+ Addons section:
