3g and 3gs lcd panel difference?

Not the glass assembly but the lcd panel. I have an iphone 3gs and I have a screen replacement for the 3gs b/c my backlight is out but I was wondering if the lcd panel of an iphone 3g would fit inside of the iphone 3gs glass assembly. I know the glass assembly connectors are different so I was wndering if the lcd panels were also. Picture below is what a lcd panel looks like
