There are TONS of interfaces to LCD panels.  Some take commands, some take raw video data, some take NTSC some take VGA style signals, some take analog, some take digital. So, start by finding out what the panel that they sell uses..

http://pubs.gumstix.com/documents/Displays/LTE430WQ-F0C_PI_Rev001_GENERAL.PDF

is the link to the PDF for that particular display for the lcd-16vx board which is sold to work with the verdex.

Within that document, you will find a few interesting things, one of which is a table with the pin out for the connector and allll the display signals that it needs, including a horizontal sync, vertical sync and 8 bits each of R G and B data.
So, it looks like it's a digital interface with video data, and horizontal and vertical syncs. 

and at .. what, 480 by 272, it is a bit of an oddball, it's not 320 by 240 which is qvga, it's not 640 by 480 which is vga, so it's an oddball size.  You could TRY a 640 by 480 display and then try doinking around with the x11 display settings file which specifies the screen resolution.. However, I thik I would tend towards finding that part of the system first, seeing what things you CAN change, and then deciding if I wanted to risk spending the money on a different resoluion lcd display afterwards.

At any rate, that document link will point you to the hardware interface of the LCD display, from there, you will have to match the interfaces between contending LCD modules.

I hope this helps, however, your mileage may vary.

hi there,
could you help me out with choosing the right LCD panel to interface
with vertex board? i'm looking in to small panels but confused by the
range of different interfaces - parallel, cmos, spi.
what would be less troublesome to implement using breakout-vx board and
available drivers?

any input is very much appreciated!
