I'm preparing some documentation for a project that is on the pipeline and I need a little bit of help. We are going to build a custom motherboard using the Intel Atom D2550. Our product will have 2 displays:
1.- Main display, connected via 24bit LVDS lines. 2.- Secondary display. It is a small display module (5.7" 640x480) and it uses the HX8250 Driver IC, which basically makes it a dumb display, as I need to feed it with 24 bit RGB data (parallel).
The Intel Atom has support for 2 displays, with the following specs:
Embedded Panel: eDP1.1 or LVDS External Panel: DP1.1, HDMI1.3a, LVDS, CRT/DAC
I'm thinking of using the embedded panel LVDS for the main display. Now for the secondary display, I have 3 serial + differential interfaces and an analog one. What would be the best way to interface any of these to the display? This is the spec[1] .
I've been thinking if would be better to do digital serial to digital parallel, but I haven't found an IC that can do this, and my only concern with this one would be EMI from the cable going from the motherboard to the display.
The other one would be the Analog to Digital 24 bit, but that would require a little more processing power I would think.
Any advise?
