Not totally sure if this is the right place to post this, so please let me know if I should move this to another topic.
I have had a Sony Dash HID-C10 since around 2010, and Sony just announced they were going to shut down the servers. My model was acting up anyway, so I decided to take it apart and see if I could put a Raspberry Pi inside—there seems to be plenty of room.
I opened it up, and the screen is the familiar Innolux AT070TN92.
It is attached to some strange digitizer, but it has the standard 50(?) wire touchscreen out.
Great—I grabbed a driver board, plugged it in, and it worked!
I was feeling pretty good, but I wanted to use the original digitizer as well. From what I can tell, this second ribbon contains the digitizer pins. It is the same number of pins as the TFT cable, but doesn't respond when plugged in to the controller board.
The only information printed on the digitizer is right under the cable, and the cable itself doesn't reveal much:
Seems like it is manufactured by Atmel, but I can't find any information on it. The entirety of the text is SEIC01-C0.02R 10D09A ELK ©ATMEL71921-A7. A google search for Atmel 71921 returns pretty much nothing.
Has anyone encountered this panel before? Any advice as to how to get this digitizer working with a Raspberry Pi?
