Hi,

I am looking into a picking up a 6.4 inch LCD from this site, for the use in a personal mobile computing project. I mean really mobile, battery mobile... I want it mainly for multimedia purposes and I am looking into a VIA based board.

(the LCD is this one)

Now most of the boards claim to have crt and lcd controllers.
like this...

Does this mean the LCD can be wired direct to the mother board OR is this a slightly fancy way of saying inbuilt video card???

Also what does PC/104 have to do with these sort of lcd control systems??...Cos my other option would be to pick up a PC/104 LCD controller board (Earth LCD is selling one for $99), which I was hoping I could connect to the LCD and the board.

The real SBC board I am after is this one...

Are there any resources you can point me in the direction of to give me some sort of idea what will be required of me, wiring, connections, etc??

I would appreciate all the help you can give me

Thanks in advance JOHN

I think it just means it has both VGA and DVI ports

The 'LCD Controllers' mentioned, are both really. You can directly control an LCD with them, if it supports that particular type. Most common type of controller is a video chip, not unlike the ones in laptops, that can use the screen directly, or output standard VGA. A second type of controller is a standalone chip that converts the signals (VGA or some digital output) from the built-in video chip to what an LCD can use. Typically, the first type only supports one or two styles of LCDs, whereas the second supports virtually every format.

PC/104, in this context, is a type of interface fairly close to the old ISA standard. A PC/104 LCD controller is basically a small ISA video card that can output to an LCD.

Edit:
One last thing. That monitor uses 6-bit digital RGB, which means it can display less than 256 colors, so that won't make a good display for your uses.
