Question about LCDs

I have some question about the crystalfontz LCDs, here is the question :
1. The graphic LCD:
a. Since the USB LCD do not have the ultra compact type as graphic LCD do. Are there any possibilities to connect the graphic LCD to a USB output, because we have learnt that the demo board you have shown for the graphic LCD is a parallel port output?
b. If there are the possibility, can you give me some ideas how to do it?
c. Do we need a specific driver ?

2. The USB LCD:
a. The output of the LCD is it a type A or Type B USB port ?
b. Do we need a specific driver also ?

I plan to connect the USB to bluetooth doogle staright to the LCD, What you think ?
Looking for additional LCD resources? Check out our LCD blog for the latest developments in LCD technology.

Sorry, but we do not provide any displays with bluetooth connections.

To make a graphic LCD work with bluetooth, the graphic LCD box would need to contain the following items:

a) graphic display (we can help with this portion)
b) microcontroller (you would have to design this)
c) bluetooth interface (you would have to design this)
d) power supply & power source (you would have to design this)

To make a character (CFAH*) LCD work with bluetooth, the LCD box would need to contain the following items:

a) character display (we can help with this portion)
b) microcontroller (you would have to design this)
c) bluetooth interface (you would have to design this)
d) power supply & power source (you would have to design this)

To make a serial LCD work with bluetooth, the LCD box would need to contain the following items:

a) serial display (we can help with this prtion)
b) RS-232 to bluetooth interface (you would have to design or specify this)
c) power supply & power source (you would have to design this)

To make a USB LCD work with bluetooth, the LCD box would need to contain the following items:

a) serial display (we can help with this prtion)
b) USB _Host_ (you would have to design or specify this)
c) some connection between the USB host and the bluetooth interface (you would have to design this)
d) power supply & power source (you would have to design this)

In all of these cases, there would be at least some software development required on the PC, the only possible exception being the serial option, which may work with standard software if you can find the serial to bluetooth stuff that has "virtual com port" functionality built into it.
