Even limiting the current a dual twelve digit seven seg display would draw a little more than 1.3 amp--- I'm not aware of any seven segment display device that is not multiplexed. The human eye is so slow that you will not notice a flicker unless you move the device in front of you. Multiplexing will reduce the power requirements to what a single digit or segment (depending how far you go with multiplexing) draws.
