Power consumption of an 8x64 multiplexed led matrix

[Dumken]

Hi guys.. Pls can someone help me with the calculation on how to determine the Power consumption of an 8x64 multiplexed led matrix.

 

[crutschow]

What's the current that each LED draws and the supply voltage?

 

[dougy83]

The average power consumption is simply the average LED current (when on) multiplied by the average number of LEDs that are on multiplied by the supply voltage, plus the power the driver/controller uses.

 

[Dumken]

20mA

 

[Ian Rogers]

20mA

Depends on the muliplexing complexity!!!
If all 8 LEDs in a single scan are all on, all 8 will consume 20mA ( if that's the average for a single LED )

Without a schematic that show the mux arrangements, current limiting resistors, and driving circuits, we got nuttin.
