Hello,

I have an SED1375 and a Hitachi TX14D11VM1CAA TFT screen.

The tft screen has a RGB 6 bit parallel interface so 18bits, the
SED1375 can only handle tft screen to 12bit interface.

My question is if it is possible to connect this tft screen to the
SED1375 and so yes, where must i connect the other pins to of the TFT
screen, can somebody give me a schematic or some explaining please?

Hello Patrick,

Yes, it is possible, just connect the "extra" bits to ground.

but, because the S1D13705 has only 80Kbytes of RAM, you can only use
256 colors.

Hello Patrick,

I would connect the lower bits, for every color, to ground.

Just use the 4 highest bits of every color.
