How to connect LCD with 18-bit interface with MCU with 24-bit interface?

I don't know if this is the right place for this question.

I have a display with a 18-bit interface (6 bits per pixel). Can I interface this with a single board computer that has a 24-bit interface (8 bits per pixel I assume).

All ouput from the board matches the display input except the 2 extra bit per pixel.

Yes you can. Look at the datasheet for the LCD panel and also the output of the SBC to match the signals. I use a SBC to interface to 12" LCD panel with no problem.

Re: TFT LCD interface

Thanks for the reply. Can you tell me how you have connected the data signals? I mean, if the computer has 24-bit interface it has 8-bits per pixel. If you look at the pinout for the board it looks something like this (red data as example):

RED 0 (Least significant bit)
RED 1
RED 2
RED 3
RED 4
RED 5
RED 6
RED 7 (Most significant bit)

But how do you connect the display with the 18-bit interface then? Because it it only has 6 connections for red:

RED 0 (Least significant bit)
RED 1
RED 2
RED 3
RED 4
RED 5 (Most significant bit)

Should I connect

(SBC) (LCD)
RED 0 - RED 0
RED 1 - RED 1
RED 2 - RED 2
RED 3 - RED 3
RED 4 - RED 4
RED 5 - RED 5

Or should I connect

(SBC) (LCD)
RED 3 - RED 0
RED 4 - RED 1
RED 5 - RED 2
RED 6 - RED 3
RED 7 - RED 4
RED 8 - RED 5

Thanks!

TFT LCD interface

(SBC) (LCD)
RED 3 - RED 0
RED 4 - RED 1
RED 5 - RED 2
RED 6 - RED 3
RED 7 - RED 4
RED 8 - RED 5

Re: TFT LCD interface

why don't try both ways and see the results but I recall I tried

(SBC) (LCD)
RED 0 - RED 0
RED 1 - RED 1
RED 2 - RED 2
RED 3 - RED 3
RED 4 - RED 4
RED 5 - RED 5
