I looked through all the bosch accelerator datasheets I could find and the
closest i could get was:

CHIP chip_id
BMA423 - 0x13
BMA456 - 0x16

I'm thinking it may be the BMA422 but that datasheet isn't available for some
reason. I did also ask in their forums but no responses. Unfortunately, I
don't think it's an easy task to disassemble the screen.
