 		 #131236 - Will not work!
Responding to: ???'s previous message
You cannot drive the common anodes of seven segment displays in the way you plan! Use the driver discussed here

http://www.8052.com/forum/read.phtml?id=64215

or solve the problem in a different way.

Also, try to find high efficiency displays to minimize the total display current.
