A light-emitting diode (LED) display is a flat panel that consists of a collection of LEDs that function as pixels. LED displays combine three colors — red, green and blue — in different proportions to produce varying colors. The three primary colors are chosen because of the three cone cells in our retina, which detect light in these colors.

LED screens are everywhere, from the screens of your mobile device to televisions and computer monitors. Bigger LED displays, meanwhile, are commonly used in commercial venues such as attractions, theaters, sporting venues, and institutions like churches and universities. Before you choose LED walls for your facilities, you may wonder how they compare in power consumption to other options.

Factors of LED Wall Power Consumption

LED screens consume 50% to 70% less energy than other lighting displays using incandescent, fluorescent and other alternatives. This reduction in energy consumption translates to bigger savings on energy costs.

So, are LED displays energy efficient? The simple answer is yes. However, the amount of savings also varies based on several factors, including:

• Screen size
• Display format, whether static or moving
• Brightness level
• Pixel pitch
• Resolution
• Color
• Refresh rate

How to Preserve Consumption

While LED displays are known for their energy-saving properties, you can still increase your savings by optimizing your LED display power consumption. Here's how:

• Switch off the screen when not in use or minimize the number of screens used.
• Turn to dark backgrounds. A black display requires turning off the LEDs, while a white display turns on all the lights. 
• Adjust the brightness level and set it to an optimal level. Look into ambient light sensors to automate brightness adjustment whether indoors or outdoors.

How Do You Calculate LED Consumption?

Follow this formula to calculate your LED wall's power consumption:

Screen Area x Power Density x Brightness = Power Consumption

Screen Area is the full measurement of the display in meters. Power Density is the amount of power in watts consumed for every square meter of display (W/m2). Brightness is the brightness percentage of your display.

For example, an LED display with a screen area of 6m x 6m, a power density of 600 W/m2 and a brightness percentage of 60% will consume 12,960 watts per square meter (W/m2). We get this by multiplying the screen area, or 36m, by 600. Multiply that result by 0.60 for 60%.
