Basically the old radio had an "inverted" display, the background pixels were on, so black, and the lettering was off, allowing the backlight to show through, so green.
The new radio's display works more like a normal LCD, so the backlight shows everywhere and the lettering is Black where the crystals are on and so black.
I'll put a picture of the old radio in my gallery after I post this.
