Salvaging TFT (touchscreen) LCD module

Other Hardware Displays
1

Hello, I would first like to thank anybody that helps me figure this out.

My teacher recently gave me an old camcorder (the Sony DCR-TRV460) that was just laying around a cabinet in the shop. As a guy who loves to take apart and recycle components, I took things apart and only kept the electronics.

The camcorder had a 2.5 inch TFT LCD module and I wanted to interface that with the arduino. I searched for the schematics and I found the documentation for the whole camera, which was great. But as I kept looking at all the schematics for the TFT LCD module, I figured out the MISO, SCK, MOSI, CS, the backlight pins but I don't know where the DC (also known as RS) and the RESET pins are.

I have attached the link to documentation of the camcorder. The only pages that only matter are 23, 27, and 32. The wires that come out of the TFT LCD module are on the top left of page 32 or you can look at the connection between Between board PD-205(the TFT LCD module) to VC-345 (the main Board) near the bottom of page 27. Page 23 is also pretty important.

Please help me in any way you can on this project. Even if you get another idea of what to interface with the arduino from the camcorder like the camera, but mostly on the Touch screen LCD Module.

Thank You so much. Arduino Community Rocks.

The LCD panel is fed data in RGB data over three lines. This can either be analog or digital - i couldn't find any evidence on what by the service manual.

The SPI lines is for control data to the LCD (gamma, contrast etc.)

The touch panel is analog.

As with almost all consumer equipment the parts are made-to-order and datasheets is impossible to get a hold of.

IF you had the time, a logic analyser and MORE time, you could sniff the data to the LCD and reverse engineer the protocol used. At that time you are still hosed if you want to use an Arduino - as it's not fast enough to push the data to the display (20 MHz+ speeds) and it does not have enough memory (there is no memory in the LCD panel, pixel data needs to be refreshed constantly)

My advice: forget the project and buy a LCD with documentation.
