I am working on a LED display board project of 16 * 288 matrix line, The 16x288 line consist of 9 boards of 16x32 leds. The problem i am facing is connection the supply to the boards, i have 3 concepts in mind can any one help me to finalise any one, My total load current is 2.7A @ 5V . Below is the conceptual wiring diagram i am planning to use

Just caught something. There is something wrong here. With a total load current of 2.7a and 9*16*32 LEDs there is ~0.5mA per LED. In sunlight you can not "see" a LED with less than 20 non- multiplexed mA (doing that every day).
