How to calculate LED display screen power consumption?

While searching for an appropriate LED display screen, power consumption turns out to be one of the important factors. While size, pixel pitch and resolution play a significant role in the selection, power efficiency finalizes the decision with the certainty of how much electricity cost they will be spending.

To begin with, buyers are required to determine the input voltage and current utilized by the LED screens. Based on a study, the best or ideal input current is around 20mA while the voltage for an LED display should be 5V. But, there are some evidences ascertaining the fact that current of the LED cannot go up to 20mA while the power consumption is expected to be 0.1W (20mA x 5V). Other than that, below are some important considerations to look at while calculating electricity consumption by the LED screens:

Power Consumption Indicators

Some of the worth considering factors explaining power consumption for the LEDs are:

Maximum Utilization
LED displays used to produce visual images from the input source with the help of individual diodes or pixels using different colors and intensities. When it comes to creating a full black screen, diodes do not work in any way whereas, for a white screen, all get to the work and stay at their maximum until needed.

According to the experts, maximum power consumption refers to a situation when the display screen works on its full power with brightness to its optimum for creating full white content. The power utilized so measured is considered to be at its maximum with small margin for environmental factors.

Black Level Power Utilization
It is a type of power consumption that enables other components, except for LED, to work without creating content. In other words, diodes are off while the receiver cards and drivers are at work and therefore, utilize some energy.

Standby Power Consumption
When the LED display is in standby mode, the same components get into the power saving mode and still need some power to keep working. This power consumption is quite below the black level. A worth mentioning fact is that content is not necessarily be white or black, it is also in different colors based on the purpose for which it is installed.
