I think that LVDS LCD cables are usually custom jobs.
What sort of bandwidth do you want?
Have a look at this, its not OLED but would it do with an LED backlight?
Its a development system and so the block diagrams and datasheets should be detailed & tell you what you want 2 know. Plus you may be able to track the LCD down as a standalone part.
I thought that the 320M cost a lot, suppose it was from a retailer though.
