power consumption led displays

One of the most asked questions is how to calculate the maximal power consumption of a LED screen. Well first of all, you should know the input current and the voltage of the LEDs on the LED screen. Theoretically, in a labratory environment the greatest input current of the LEDs on a LED screen is 20mA, and the voltage for the LEDs for the LED screens is 5V. But in reality, the current of the LEDs of a LED screen can't reach 20mA. So the power consumption of a LED is 20mA x 5V = 0.1W. So it is very simple how to calculate the power consumption of one LED on a LED display.
