Pins on a Sharp Cellphone LCD

Posts: 12
Hello everyone!
I recently opened my old cellphone (a Siemens MC60) and discovered that the LCD (a Sharp N1422CP) was removable and thus should be fairly easy to wire up in another project. Free (small) color LCD!
The problem is though that I can't really figure out the pins, which pin is VDD, VSS; DATA etc. Does anyone have any experience from these things and might have a clue or two to share? Or perhaps a link to the datasheet? I have been googling for a couple of days now, but the only thing I have found is that Sharp dont release the datasheet for products that have been used as a part in comercial products. I have been probing the connectors on the phone with a voltmeter and found out that it uses 3.3 V and 5.8 V, but when I try to connect that voltage to the display nothing happens.
The display is a 96x80 px LCD (AFAIK) with 10 connectors (if it may help).
Any hints?

···These LCD Displays are usually custom, and you would be hard pressed to find a controller to directly interface to the LCD.· Chances are it would require one to use it, and you don't have that.

I think it is easier to buy a lcd that there is info available about.
I found 2 old displays that I'm going to try later (2x12 and 3x12 characters I2C bus)

The item that REALLY PERKED my interest is that some of these already have a 3 line serial inferface.
Most graphic LCDs originally interfaced with an 8-bit dot matrix controller and required you to output your data via parallel lines.
Additionally, there is quite a bit of ram on-board.
