I have a display from Panasonic car stereo (Toyota Corolla), but can't determine how to work it. It's called Optrex F-51684, and there is no datasheet for that LCD. Is it possible to find how to work with it without datasheet? This is screenshot of the connector pins from main board:
So it has a serial interface, i can select a chip here (CS1 and CS2), but also there is an unknown pin LCD-DET.
I thought it has S1D15605 (like nearest Optrex LCD-s) controller but pins seem different. Also there is chip on the module, marked as EF766102 B01 R ,without any information about it on the internet. Same time it has a name IC2 so it should be second chip, but there is no sign of IC1. Can it be hidden somehow?
