One of the factors that made LED displays popular and a top choice for many is their energy efficiency. These energy efficient displays use LEDs, which compared to regular and incandescent light, can maximize electricity usage to 90 percent. This is how LED displays were named energy screens in the first place. 

LCDs were incredibly popular before LEDs were introduced to the market. The problem though is that LCDs use too much electricity. Compared to the LED display power consumption, it is significantly more wasteful and expensive in energy usage. They cost more due to the complexity of their manufacturing process. 

If you care for the environment and your savings, checking out energy efficient displays is a good step to take. As long as you thoroughly scour all the information you can find about these screens, you won’t regret investing in them. 

What Is an Energy-Efficient Display?

An energy efficient display technically refers to an LED display. This display can operate using less energy, making it a more sustainable and cost-effective choice compared to other types of screens. An LED display is a more sustainable solution because it often lasts longer than other screens offered. 

LED displays are also a cost-effective solution because they use the most energy efficient display technology for their screens. With this, the screens consume less energy, which translates to a reduced electricity bill you’ll have to pay. It is one of the reasons why these displays remain popular worldwide and in every industry in the global market.  

Big outdoor LED screens are particularly popular because, before the use of this energy-saving technology, many of the massive displays consumed a high amount of power, leading to a high electric bill. The bigger the display, the higher the kilowatts used to operate. This is different from the LED signage wattage, which is low and significantly reduced compared to the consumption of LCDs.

Features of Energy Efficient Displays

What makes energy efficient displays the way they are in their composition and the features that are integrated into them. Technically, these displays were improved not just through the new LED technology but also its hardware and overall program. While the common LED displays are already energy-efficient, there are LED screens designed to be more than that.

Here are some of the major features of energy-efficient LED displays that make them energy screens. 

  • Produces less heat resulting in fewer issues of overheating
  • Prolonged lifespan compared to other displays
  • Less vulnerable to weather elements and temperature changes
  • High brightness with low working voltage
  • Reduced electromagnetic interference
  • Low power supply reducing unnecessary power losses
  • Unique design of PCB board
  • Energy-saving (20 to 25 percent energy savings) driver IC
  • Power consumption: 487 kW/hr per LED module square (50 percent energy savings)

Power Consumptions of Energy-Efficient LED Displays

Energy efficient displays have low power consumption, increasing the energy and money savings all at the same time. Different factors affect the power consumption of LED displays but before getting one, you need to know the average power consumption for standard LED displays and the one for energy-efficient LED screens. 

When an LED display uses green technology, it can save up to 50 percent of the usual power consumption of LED screens. A common LED display can use around 100 to 1000 W/m², depending on some of the factors that can affect the consumption. 

LED Signage Wattage: How to Calculate the Power Consumption of an LED Signage

To get the LED signage wattage, you will need a wattmeter to measure your power consumption. There, the electricity flowing in the device will be measured and the wattage will be displayed in watts or W. The problem with using a wattmeter though is that many incidents have been recorded with inaccurate readings. This is the reason why you need to learn how to compute for power consumption. 

To get the accurate value of the power consumption of your energy efficient display, you need to learn how to compute it. First, you need to find out the components in the computation, including the daily working time, screen size, and the current rate. Here is the basic equation:

Electric Cost = Rate x Power Consumption x Screen Size x Daily Working Time x 365 days/year

For a 60 sqm energy-efficient screen that’s operating for 15 hours a day using the rate of 0.2 USD/kW and power consumption of 0.12 kW/sqm, this is the computation:

Annual Electric Cost = 0.20 x 0.12 (kW/sqm) x 60 sqm x 15 (hours/day) x 365 (days/year)

Annual Electric Cost = 7884 USD

You can also compute the savings by using the average power consumption of a traditional LED display, which is around 0.28 kW/sqm.

If you’re bad at Math and don’t want to manually calculate, you can use online calculators for your LED screen power consumption for convenience.

Factors Influencing LED Display Power Consumption

If you’re conscious about the power consumption of your energy efficient displays, you should be aware of the different factors that affect its value. Generally, standard LED displays use more energy compared to energy efficient screens. These are the components that make it possible to have less power consumption. 

Brightness Level

The brightness levels of the LED screen affect your power consumption. More power is generated when a high brightness level is used in the display. This means that brighter LED screens often have a higher electricity bill. It is higher with traditional LED displays and so much worse with LCD screens. 


The type of content also plays a role in the display’s power consumption. If you’re playing videos and animations, chances are you will use more power compared to when you’re just displaying text or images. 

Color Contrast

The color contrast of the energy efficient displays will also influence the power needed for the screen to operate. Some colors require more energy like white while others need less power like black. 

Pixel Pitch & Resolution

The LED screen with a higher pixel pitch will require less energy while a lower pixel screen will need more energy. This is because these LED displays with low pixel pitch often form a high resolution. More power is required to successfully produce these vivid images in high resolution. 

Refresh Rate

Energy efficient displays with a faster refresh rate often use more power. The refresh rate is how fast the display updates with every reload of the images. This means that an LED display with 240 Hertz needs more power than a screen with a 120 Hertz refresh rate. 

Screen Size 

The bigger the screens, the more energy it requires to operate. If you want to save from power consumption, you can choose a smaller display. 

How You Can Save Your LED Display Energy Consumption

The best thing to do when using your LED display is to maximize its use. More than that, you can also do some things that can help you save on your power consumption. Besides getting an energy efficient display, you can also conserve energy through the following:

  • Set the brightness of your LED screen to the optimal level with an ambient light sensor
  • Prefer LED displays with bigger pixel pitch since they consume less power
  • Make sure to turn the LED screen off when not in use
  • Turn the “energy-saving” mode on since most LED displays are integrated with this feature
  • Look into the manufacturer of the LED screen before purchasing screens that are labeled as “energy-efficient”
  • Use darker-colored backgrounds for your LED displays because they consume less energy than other brighter colors
  • Put the refresh rate at the appropriate level and not too high since it consumes more power


Investing in energy efficient displays means you purchase a screen that can bring in more savings the longer you use them. They are sustainable and cost-effective, with savings both in terms of the power consumption and the finances. And maximizing the use of your LED screens will also help in making sure that you get the best of your investment. 

Getting energy-efficient LED screens will make a significant difference compared to getting a traditional LED display. Besides the fact that you get to save 50% of power consumption and savings from the electric bill, the device is also bound to last longer. You can adopt energy-saving habits that can help you reduce your screen’s power consumption and increase your savings in the process. One of these habits is learning how to compute the power consumption of your energy efficient display to anticipate what you’ll need to pay for.
