What kind of coding do I use to operate a touch screen like this Sharp color 24 bit LCD? I want to input data, and display data with this. The back-lit LCD is kind of crude looking, I want sharp graphics.

Well finding actual technical specifications would be better than posting jpg files of what it looks like.
And it would be programmed in much the same way as any other LCD (or indeed any other device).
You read the specs, and you find out what messages (sequences of bytes) to send to it to make it do various things.
Then you write simple wrapper functions around the more useful ones to say
- goto a point on the screen
- display a pixel
- display a character.
Does it have an embedded microcontroller for controlling the display. If not then shop around for one and as noted start with the device specs.
I'd like to program something like this...!
May be a bit of an overkill for what I need though.... :)

Ok Robert, let me give you some idea what you're getting into, starting with what is essentially a replacement part...
You will need to...
1) Design some sort of microcontroller based hardware to drive the display.
2) Design and implement imbedded code for the microcontroller.
3) Come up with an interface to whatever host you plan to run it on.
4) Write drivers for that interface to bridge between your microcontroller and host.
5) Write a C library to communicate with your driver in some reasoned manner.
6) Write your actual application software.
So we're talking about everything from designing a case for it all the way to writing application software... and all steps inbetween.
Does this sound like something you want to do?
I'll try to buy a ready made unit that looks like a cell phone, or a gps, with programming guide.
I realize now that just putting a touch screen over a display is quite a task.
I think ready made programmable units can be found.
That is probably a saner approach...
:)
Did find an interesting thread on the subject though...
