Driving larger LCDs

I'm sure this question has been asked before but I guess my searching skills are just complete fail today.

I'm wondering if someone could give me a primer on what it would take to set up a project and use an LCD like one of these: http://www.sparkfun.com/products/11075

Preferably not just a parts list, if possible. Or a link to a guide would be nice if one exists.

I know an arduino can't drive one of these things, from what I have been able to find it takes an ARM chip. But I haven't really been able to find much on how to get into creating projects around an ARM chip, programming them, etc.

The device you have called out can be programmed from a simple serial interface, nominally @ 9600 baud but that can be changed it has 2 extra serial ports a 16 bit output port that can be an 8 bit bi directional parallel port. It will read an SD card (mini) it has a touch screen. Here is the link to 4D Systems. http://www.4dsystems.com.au/prod.php?id=155. This link will take you directly to the display. This display is the most powerful and easiest to use part I have yet to see. It is easily used with an Arduino Uno it just requires 2 pins and the standard software serial feature of the Arduino IDE. Expensive but in my opinion very well worth the money.

Oh yeah, I forgot that one said something about having some type of programmable chip in it. The other one I was looking at was the psp display sparkfun has that doesn't have such a chip. So I guess it was a bad one to choose lol.

But on this LCD in particular, having not read through the documentation yet (will do that in a bit):

I'm guessing you have to write a UI program more or less in the 4DGL and you could program it to forward touch inputs to the arduino through serial, and arduino could respond back with commands through serial which the program on the LCD controller would have to receive and handle?

It's got a built in SD card that you can use to store media and stuff on, but what if you need to display something that isn't on that SD Card, say for example a pic from a camera, can it do that in some way? Or do you have to use the serial connection to somehow transfer it to the SD card and then display it through the 4DG code?

What about a LCD display like this one:
https://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2157554_-1

It says it includes the driver but no controller. What would you need to do for a controller to be able to use that screen with an arduino or even a netduino project?

It's not physically possible to drive that with an Arduino. The pixel-clock needs to be ~10Mhz and you'd need to constantly supply data to the display at that frequency from a framebuffer that you don't have.

Yes I'm aware of the fact that you can't drive it from an Arduino directly. That is why I'm asking what you would need.

Your cheapest option would be an SSD1963 at ~$7 from techtoys HK. Other options include an ARM with an LCD interface, a CPLD or an FPGA.

Thanks for that part list, but care to shed any more light on it? What exactly would I do with those... whatever they are. Obviously I don't know much about this, I'm trying to learn which is why I put this in my original post:

I've developed a Serial_LCD Serial Suite for 4D Systems Screens for the 4D Systems screens.
