If you are quite frugal in all the decisions you make, investing in LED displays may be one of the smart choices you can make. When LED technology replaced LCD technology in the display industry, many advantages of the newer and more advanced technologies have resurfaced. One of which is the supremacy of the LED display power consumption. 

LED displays are known for so many things, including their high levels of brightness, flexibility, and scalability, and finally their low power consumption. With all of these benefits, it’s difficult to say no to LED screens. But what does it mean to own an LED display and will it empty your pockets just using this advanced device? 

You can always have an LED screen power consumption calculator in hand to easily measure the possible costs of using an LED screen. However, it’s still better to have a general idea of what you can expect from your LED display. To know more about LED power consumption and what it entails, read on and find out.  

Introducing LEDs

LEDs are the tools responsible for turning LED displays into energy-saving machines. Light-emitting diodes are semiconductors used in this advanced display that help maximize the use of the technology. Through the gallium arsenide-made diodes, light is produced once power reaches them. 

LED maximizes the use of electricity, with 90 percent accuracy. This means that there’s very little waste in terms of energy, unlike incandescent and standard bulbs. The best thing about LEDs is that they don’t use filament, which leads to the following advantages:

  • Produces less heat compared to other lighting sources
  • Less prone to shock and damage
  • Less susceptible to weather changes
  • Do not have instant temperature changes
  • Prolonged lifespan

Before the use of LEDs, LCDs were the popular choice. They provided the necessary stepping stone to jumpstart advanced display technologies. Unfortunately, LCDs come with disadvantages and elements that need improvement, which is why newer and more advanced technologies were developed. Some of these disadvantages are the following:

  • Poor brightness
  • Low contrast
  • High power consumption and waste
  • Complex production process
  • Expensive manufacture costs

From all of these disadvantages, LED display was developed to improve and get rid of them. One of the elements that made the newer technology superior is its efficient LED display power consumption. LED screens operate by using and wasting less energy and even last longer compared to LCDs and CRTs, which are the traditional displays before LED screens. 

Over time, this advantage will even be more prominent and you will clearly see the benefit of choosing LED display over other screen types. Costs of repairs and replacements are rare and the savings you get from low energy consumption will pile up. 

Factors Contributing to LED Display Power Consumption

LED display power consumption refers to the amount of electricity that the screen uses while it’s operating. Fortunately, compared to other types of displays, LED screens are considered energy-saving and environmentally friendly. While the use of this screen does not use as much energy compared to other types of displays and lighting fixtures, it still needs electricity to power its operation. 

If you’re curious about what factors can affect the LED display power consumption, there are several that you will find influential, including the following:

LED Screen Size

LED displays come in a variety of sizes and more often than not, the size influences other aspects connected to the screen’s operations. When it comes to LED display power consumption, bigger LED screens are bound to consume and use more energy in order to power more diodes in the panel.  

If you have a limited budget, try to consider smaller LED displays if it fits your screen needs. However, since the devices use less energy anyway, you can go as massive as needed in screen size

Pixel Pitch

The pixel pitch can also influence the LED display power consumption. When an LED screen has a low pixel pitch, it will need more energy to power its system compared to a screen with a higher pixel density. Low pixel pitch means that there are more diodes to power since they are closely grouped together with very little space in between them. 

Resolution

Similar to pixel pitch, the resolution also affects the LED display power consumption. In order to produce high-resolution images, an LED screen needs to have low pixel density where the diodes are arranged closely together. This means that more diodes are used and so more need to be powered by electricity. 

If you’re enjoying LED displays with high resolution, chances are you’re paying more for their electricity compared to others with low-resolution displays. 

Brightness Levels

The brightness of your LED screen can affect the amount of power it uses just to be able to operate. When an LED display has high brightness levels, it uses more energy to produce enough power to accommodate these high levels. This only means that outdoor LED screens consume more power since they need high levels of brightness to be able to operate under the heat of the sun. 

Variety of Colors

Colors can also affect the LED display power consumption, with specific colors requiring more power than others. For instance, if there are many dark colors like black in the video or image displayed on the LED screen, it consumes less power compared to a display that shows a bunch of bright colors like white and yellow. 

Refresh Rate

When it comes to the refresh and update rate of the LED display, it is notable that the screens with higher rates use more power for their operation. If you have an LED display you use for gaming that has high specifications for refresh and update rates, you are bound to spend more power compared to a simple display LED playing a video presentation. 

Content-Type

Finally, the type of content you’re showing on the display can affect the amount of power it consumes. If the screen is simply showing a static image or text, it doesn’t take up too much power compared to when it’s playing a 3D animated short for a marketing stunt. 

LED Display Power Consumption & Costs Based on Type of LED Displays

The average LED display power consumption of advanced screens ranges from 100 to 1000 W/m², depending on specifications that can affect its needed power like the factors mentioned above. This LED power consumption affects the electric bill you will need to pay. To give you a look at what you can expect to pay, here is a table consisting of different types of LED screens with the average power consumption. 

LED Display TypesAverage Power ConsumptionPossible Cost
Indoor Full-Colored LED Display (P4/P6)290 W/m$500/m
Outdoor Full-Colored LED Display (P6/P8/P10)375/400/450 W/m$650/$700/$790
Energy-Saving Outdoor Full-Colored LED Display200 W/m$350/m

Measuring Costs Without An LED Screen Power Consumption Calculator

Let’s dive into some technical terms and figure out how LED display power consumption is computed in the first place. To put numbers into values, here is the general formula used to know what the power consumption is:

PC = SA x PD x B

Legend:

  • PC – Power Consumption
  • SA – Screen Area (in meters)
  • PD – Power Density (W/m²)
  • B – Brightness (in percentage)

Suppose you have a 5m x 5m LED display with 500 W/m² of power density and 75% brightness, your LED display power consumption is measured at 9,375 W/m². This shows the amount of energy used by the display for every square meter. Just using this formula, you can easily compute the power consumption of the device. 

If you don’t want to do any math or get a calculator and do some computations, you can use a wattmeter instead. If you connect this to your LED display, you just need to look at the number displayed on the wattmeter and that’s your LED display power consumption. If you’re the pessimist type who doesn’t easily believe what you see, get a pen and paper and do some awesome computations then. 

Tips to Follow to Maximize Your LED Power Consumption

To get a handle on your LED display power consumption if you think that it’s still too much for your budget, here are some hacks you can follow to lower your electric bill and save money for other priorities. 

Choose Dark Background

If you can control the content you play on your LED screen, you have the capability of saving more from your LED display power consumption. Choose a dark background to avoid using too bright colors, like white and yellow, that consume more energy. 

Put the Energy-saving Mode On

If there’s an energy-saving feature in your LED screen (the majority does have this feature), turn it on to take advantage of the feature. The built-in feature can help reduce your power usage and your electric bill at the same time.

Don’t know how to turn it on? Go to the manufacturer’s manual of your LED display and check out how to do it. Many displays have it available under the setting, specifically the power management system. 

Use Optimal Brightness Level

Use your LED display at its optimal brightness level so that you can maximize energy use and lessen power waste. If you don’t know what brightness level to set and how to set it, use the automatic setting feature of the ambient light sensor.  

Choose Appropriate Refresh Rate

Since a high refresh rate consumes so much energy, choose the rate that’s just enough for your display needs. If you won’t use it to display high-speed motion like the ones seen in games and action-packed movies, you can lower the refresh rate too. reduce your utility bills too.  

Get To Know The Manufacturer

Some LED displays surprisingly don’t qualify as energy-saving. If you want to make sure you have a cost-effective device, research the manufacturer before even purchasing the LED display. Check out if you’re eyeing an LED display with high luminous efficacy and make sure to research if its manufacturer is popular for producing energy-saving devices. 

Turn Your Screen Off & Unplug

If you’re not using your LED display, just turn it off. Nothing good can come from an open LED screen that doesn’t do anything except consume energy and increase your utility bills. 

Conclusion

LED display power consumption refers to the amount of energy used by your screen and it affects your display’s performance, as well as the electricity bill you’d have to pay for every month. Fortunately, LED displays are the epitome of energy-saving devices so you’re guaranteed to have a lower power consumption compared to other displays. Just make sure you’re actually using an energy-saving device since some LED screens are not designed that way. 

Now that you know how to compute LED power consumption, you can have a general idea of what to expect from your electric bill. If you’re not satisfied with the numbers, you can follow some of the tricks mentioned above to further reduce your expenses.
