Hello, I am working on a device and I have chosen 2 2.3" 7 segment hi-red LED displays to go in it.

as you can see, it says
Electro-Optical Data (@ 20 mA)
[SIZE=-1]Forward Voltage - Typical: 7.40 V[/SIZE]
I plugged that information into LED wizard and it told me the typical 7.4 was very high. Then after researching around..everyone says a red led is usually around 1.7-2v.
is this just because of how big the display is? Or is the 7.4 for all 7 segments, and I need to divde that number by 7 to get my typical forward voltage?
