Will a black wallpaper on your cell phone save energy if you have a WVGA display?

I read that black wallpaper will save energy if you have an AMOLED display, but I can't find any info about WVGA displays. I have the HTC Thunderbolt.
 
yes it will thats why android 2.3 have a black skin UI and they said it saves battery so i think the background will do the same
 
try to get the extende battery and run advance task killer and fix the setting like kill apps ever 30 min and stuff like that it should give you more life i have the thunderbolt with extende battery and last me about 18 hours
