Bosch Integral TH13 LCD dislpay
« on: March 22, 2019, 12:38:29 pm »
Hi all,
I've got three LCD displays used in Bosch Integral TH13 phones.
6 inch size,  B/W.
The model is SII 4141, controller chip is LZ93A76 also made by SII
I don't know how to use it and I don't find anything about it on Google
Please see the attached picture.

the lz93a76 is a timing generator, the controllers display drivers are the two rectangles blob in the flex cables

do you have other markings on the lcd ?

No. The PCB in the picture contains all the markings and integrated circuits. (except the blobs for the columns driver)

Thank you Coromonadalix for the information
I manage to obtain the mainboard of the Bosch Integral TH13 phone.
The controller chip is SED1330F.
The datasheet is available online.
The datasheet for the rest of the chips was easy to find.
The only unknown chip is CG24942 made by Fujitsu. (it looks like a character generator ROM)

Niice   an SED1330f  is relatively easy to work with

Lots of code in the arduinos forums ...  if you could trace the signal paths with the th13 boards  youll have your 15 pins connectors schematics

Not sure  it seems to be an hirose connector ?

I'm not sure about the connector. It has 15 pins. Next I'll try to map the connector pins to SED1330F chip pins. Then I try to use the RAM and character generation chip on board TH13 with some Arduino code.
