The change is quite small in comparison to overall display power consumption, but it held true across multiple display panel types (TN, IPS), and backlight sources (CCFL, LED).

It seems the power variance is somewhat dependent on the LCD in question. However, I tested three different LCDs, which use different panel types (TN, IPS), Backlight sources (LED, CCFL), and the increase in energy to display a black subject was common across all of them.

The power draw is specified in ranges because the readout measurement on the Kill-A-Watt is somewhat noisy. I took measurements by letting the monitor sit at the specified display image for a minute or two, then monitored the maximum and minimum value displayed on the Kill-A-Watt. Those are the numbers reported for the range in each monitor"s power draw.

The Only situation where something like Blackle would be of use, or indeed beneficial is with OLED Screens. These screens effectively have a backlight-per-pixel, and they do indeed save power when displaying dark scenes.

However, with any modern single-backlight LCD, the only effect on power draw is the actual panel"s power draw, which increases as the transmitted light decreases, the inverse of what Blackle claims.

A home without a TV set is more the exception than the rule in the U.S. Many households even have a couple or more. Well, watching TV is one way to relieve stress and boredom, so we can’t blame you if you have a TV in every room. But if you aim to lower your energy consumption, it will be a good idea to find out how many watts a TV use. In that way, you can limit your TV viewing to see a reduction in your electric bill.

How much electricity a TV set uses depends on several factors, such as your TV’s size, age, and the like. In general, a television’s power consumption falls between 80 and 400 watts. So if electricity costs $0.13 per kWh in your area and you leave your set on 5 hours a day, expect your viewing to add around $7.13 a month to your energy expenses.

However, as we said, how much electricity a TV consumes varies. A 24-inch 2080p model will use far less power than a 75-inch 4K QLED one. So if you want to save electricity, knowing the factors that affect your TV’s energy consumption will help with your goal.

Cathode-ray tube (CRT) models: These types were the only models you could find for the longest time. Their energy consumption is around 60 to 100 watts per hour. ACRT TVconsumes about 2-3 watts an hour in standby mode.

LCD models: The size of the panel determines how much power an LCD TV consumes. The median model has a 32-inch panel size, with an electricity consumption ranging between 40 and 55 watts. In sleep mode, this type uses up a minuscule 1W per hour.

LED TVs: Being more energy-efficient, the power consumption of LED TVs is 40% lower on average than other models. Compared to LCD TVs of the same size, one with an LED panel uses up around 50 watts per hour powered up and only 0.3 watts in sleep mode.

Plasma TVs: These models aren’t as energy-efficient as LCD or LED types. The average electricity consumption of a 30-inch TV is around 150 watts per hour. In sleep mode, the plasma TV consumes about 0.5 watts.

You’ll need three essential pieces of information if you want to calculate your TV’s power consumption. These include your unit’s wattage, hours of TV use, and the electricity rate in your area. Use the following formulas to find out how much you pay for your TV viewing.

TV models in the market have wattages between 80 to 400 watts. So let’s say you have a 50-inch LED TV with a rated power of 100 watts, and you use it for 12 hours a day.

Before the invention of the different models, only the size of a cathode-ray tube TV determined how much energy the unit consumed. Advances in technology created various models, some of which are more power-efficient than others. Nowadays, how many watts a TV consumes depends on several factors aside from its size. So if you want to know how many watts a TV use, you’ll need to look at the model.

The older your TV set, the higher its electricity consumption. For example, the energy usage of a 32-inch CRT model stands at 150 watts, on average. Compare that with a newer LED TV of the same size, which is between 40-55 watts and a maximum of 70 watts per hour.

Aside from the reduced power consumption of newer models, upgrades in technology also led to better picture quality. So it’s not just a matter of how many watts your unit consumes but also the viewing pleasure it brings.

The second most significant factor determining how many watts a TV consumes is its size. For example, a LED model 15-inch TV needs only around 15 watts to operate. In contrast, one with a 50-inch panel uses 50 watts an hour. This proves that the size of your TV affects how much power your home draws from the grid. In fact, each upgrade in size will increase the watts your set uses due to the resolution enhancement of the unit.

The display technology used in your TV will affect its power usage and hence, your electricity bill. An LCD and LED TV are comparable when it comes to energy efficiency. Older CRT and plasma screens are substantial energy drains compared to newer screen types. CRT and plasma TVs use around three times more electricity than their LCD and LED counterparts. If you have a TV set using the older technologies, switching to an LCD or LED set can help lower your electricity bill.

Knowing some important terms will allow you to calculate your appliance’s power usage correctly. This will significantly aid your efforts to lower your home’s total energy consumption. These essential terms are the following:

All TV sets have corresponding wattages, which vary depending on the factors we’ve mentioned. If you want to know the wattage of your flat-screen TV, for example, look at the back of your appliance. You’ll usually find a small silver sticker detailing the technical specifications of your unit. These specifications include the wattage, input voltage, and the like.

Undoubtedly, a CRT TV drains more electricity than its LED counterpart. Screen size notwithstanding, the older technology is less energy-efficient, making the old tube a power hog.

A CRT set can use up a whopping 400 watts depending on the screen size and other factors. Plasma screens come second in terms of energy usage at about 150 watts, followed by LCDs which suck up 165 watts of power. LED TVs are the most energy-efficient, as they use up only 155 watts.

Although TV sets aren’t the top energy users in a home, they still consume electricity, and this power consumption can significantly add to your total electricity usage. Thus, they can potentially increase your monthly electric bill. However, you won’t have to give up one of your sources of entertainment to see some savings on your utility expenses. Reducing the amount of power your set draws is the key to your goal.

The backlight drains the most power among your television’s components. Lowering the backlight level will also reduce your set’s energy consumption. Installing your device in a dimly lit environment will lessen your need for a bright backlight. Modern units usually come with a built-in light sensor. Turn it on to automatically optimize your set’s brightness setting.

Turning off your TV set is the best way to reduce its power consumption. Better yet, pull the plug off the socket. The energy consumed by even a 100-inch TV falls to zero if it’s disconnected from a power source. This may seem like a no-brainer, but many people leave their sets on all the time. They may use it for some background noise or don’t even notice it running. Make a conscious effort to power down your set to see some savings on your electricity bill.

You likely have several components connected to your TV. Examples of these are your home entertainment system and gaming consoles. These devices may remain on standby mode without your knowledge, making them continually use electricity. Like with your television, make sure you completely turn off all the accessories attached to it. Using a smart power stripmakes it easier to cut off the power for these devices.

Just because an appliance isn’t powered on doesn’t mean it’s not drawing energy from the grid. Electronics usually have a standby mode setting. In such a state, they continue to consume electricity. Standby power will use about 2.5% to 5% of electricity. The amount may be small but it can add up, especially if you leave all your appliances in this mode. So turn off your set completely when it’s not in use. For greater convenience, you can plug your TV into a smart power strip which turns off devices that are not in use.

The “always-on” feature on your set lets you enjoy viewing ease older generations never dreamed of. Imagine being able to turn on your TV by voice command to a smart speaker. The downside? This feature adds to the set’s electricity usage. You can lower your appliance’s energy consumption by almost 50% by turning off this feature, especially if it’s an Energy Star model.

The best location for your TV depends on your viewing habits. In general, install it in a lighted room to save on the screen brightness. However, if you prefer a theater-like ambiance, place the set in a dimly lit room and adjust the contrast, setting the brightness control to low.

Electronics that remain plugged in continue using electricity even when they’re not running. There’s even a term for the power consumed by electronics that draw electricity. It’s called vampire energy. To prevent wasting electricity, pull the plug off the socket. Alternatively, you can use a smart power strip. You can save around 5 watts by using this technique.

A smart TV is an excellent investment when it comes to reducing your power bills. It has many features that can help lower its power use. Better yet, get an Energy Star-certified model. Appliances with this seal indicate that they consume less electricity (by about 30%) than conventional models. They may cost more upfront, but you can get back your investment through the savings on your utility expenses.

Next to the old CRT models, plasma TVs consume the most electricity among the newer screen types. Their picture quality may be terrific, but eco-friendly, they’re not as they need more power to operate. The higher energy usage may not be enough to show a dramatic spike in your electricity bill, but the small amount adds up. OLED and LED TVs are better alternatives.

Many TV brands and models now come with the energy-saving mode. The feature may be called by different names, such as eco-mode, or it may be part of an Ambient Light Detection selection. But it serves the same purpose, which is to save electricity consumption. Find out if your set is equipped with this feature and use it as much as possible. Not only will yousave money on your bill, but you’ll also reduce your home’s carbon footprint.

Although other factors come into play that can affect the TV’s power consumption, size is a major consideration. That’s because it takes more electricity to power a large screen than a small one. For example, a 30-inch LED TV uses between 50 and 60 watts, while a 42-inch one consumes between 80 and 100 watts.

Appliances that have a standby mode consume electricity even when turned off. This energy use is called vampire power. Computers and equipment related to computer use (i.e., modems, routers, etc.) rank first in the list of appliances that use vampire energy. Instant-on TVs come next.

The answer to how many watts a TV consumes depends on a few factors, such as screen size, type, model, and set’s age. Even your TV use affects your unit’s energy usage. Plenty of screen time significantly drives up your monthly electricity bill. If you aim to shrink your monthly electricity bill, there are some measures you can employ. These include buying a smart TV, lessening your TV use, and following our tips for reducing your appliance’s power usage. Some homeowners even opt to power their sets using solar panels.

In the end, it’s not just about saving money on your energy costs but also about helping the environment. By lowering your home’s electricity consumption, you join the efforts to lessen the greenhouse gas emissions that warm the planet and accelerate global warming.

Power consumption is a decisive parameter when comparing LED displays. If you are researching into your options for an LED wall you might have wondered why the power consumption values for certain LED products are higher than others. The answer is simple: the values are based on different calculations. And you shouldn’t compare apples and oranges. So allow us to demystify the seemingly inexplicable differences in the LED power consumption specifications.

Energy efficiency closely relates to the total cost of ownership of your product (TCO). Restricted power consumption levels mean electricity expenses are kept to a minimum. In addition, it goes without saying that power consumption is crucial when it comes to sustainability objectives. Energy efficient products also reduce your eco-footprint and are generally better for the environment.

So yes, you should definitely look at the power consumption information when deciding on a new LED video wall, but be aware that in order to make a thought-through decision you need transparent spec information.

LED recreates the visual content sent from the input source by lighting up the individual pixels or diodes to different intensities and colors. To show a full black screen, for instance, all diodes are switched off; whilst to present a full white screen, all diodes are powered to their maximum.

The maximum power consumption is defined by recreating a situation where the LED wall is going full power, the product is set to full brightness showing full white content for a certain amount of time. The power consumption measured in this way is the maximum power consumption spec of your product, of course taking into account a small additional margin for environmental variables.

Black level power consumption refers to the power needed to run the electronics without showing content on the LED wall. Because even though the diodes are off, the drivers and receiver cards are still consuming energy.

When the LED wall is set in standby those same electronics are still working albeit in power saving mode. So, the standby power consumption is below the black level power consumption, but obviously still higher than when the display is completely turned off.

Now, content usually isn’t just full black or white, but shows a variety of colors depending on the application where LED wall is used for. That’s why Barco always refers to “the typical power consumption”.

The traditional industry rules of thumb (dividing the maximum power consumption by three) usually don’t take into account the average use and black level power consumptions. For outdoor products with low pixel density and only a couple of drivers, this was on average a correct calculation. But with today’s high-resolution indoor LED products, the black level power consumption has become an important parameter which shouldn’t be left unnoticed. Pixel-pitches are significantly lower, think of the XT0.9 tile, and the pixel density on LED tiles is increasing. More pixels naturally need more drivers to manage the wall. The power consumed by these drivers and extra electronics is not neglectable. Hence, it’s only logical to include it in your calculations. The result will be much closer to reality!

Barco’s calculation of the typical power consumption is based on the black level power consumption, the maximum power consumption and an average usage of the LED wall. On average a customer configures the display at 70% of its maximum brightness, and the typical content on the wall consumes only 33% of that power.

In this calculation we assume that the content consumes only 33% of the configured power, but as we indicated earlier it all depends on the application area and the typical content shown on the display. Suppose you install an LED wall in a lobby to welcome your business visitors by showing your logo and the visit’s schedule on a white background. Since the white requires more power, the average power consumption of this content will be higher than 33%, and the total typical power consumption for this specific case will also result in a higher number. If you install the same LED wall in a control room where predominantly black SCADA1 content is shown, the average power consumption will be lower than 33% and the typical power consumption significantly smaller than in the lobby.

Yes, one and the same LED wall can have different typical power consumption levels in different environments! Each application has its own typical visualized content which has a huge impact on the typical power consumption.

The green computing movement demands that all computer users shed the energy-wasting practices to which they"ve grown accustomed—so you decide that you"re going to power down your PC at night, invest in an Energy Star–approved laptop, and only visit Web pages that eschew white space in favor of ostensibly more energy-efficient black backgrounds.

Before you tune out and turn off, you should know that black isn"t necessarily the new green. Because computer monitors come in a variety of shapes and sizes, and not all monitors create black and white the same way, there"s no proof that, on the whole, increased usage of black images would save more energy than the continued use of white ones. In fact in newer liquid-crystal display, or LCD, monitors white is actually slightly more energy efficient than black.

The notion that black screens save electricity certainly makes sense when you"re talking about cathode-ray tube, or CRT, technology that works by moving an electron beam back and forth across the back of the screen. "The front screen is covered with red, blue and green phosphors," says Bill Schindler, vice president of electrical engineering for Panasonic Plasma Display Laboratory of America. To produce white, the electron beam is directed at the phosphors. However, "when the screen is black, you don"t have to fire the beam," he adds.

CRT monitors, which until a few years ago were the predominant models among PC users, consume more power when a computer screen is white. To confirm this, Schindler measured the energy output of an 18-inch (45.7-centimeter) CRT monitor and found it used 102 watts when the screen was white but only 79 watts when the display was black.

This is not the case, however, with LCD monitors, which have no phosphors and represent the lion"s share of every new monitored purchased in the developed world, including those used by laptops. Instead, LCD displays rely on an array of thin-tube fluorescent bulbs that provide a constant source of light to create a white screen. To make it black, LCDs rely on a diffuser to block this light. As a result, LCDs use more energy than CRTs to display a black screen. Measuring a 17-inch (43-centimeter) LCD monitor, Schindler found that white required 22.6 watts, while black came in a tad higher at 23.2 watts. With a 20-inch (50.8-centimeter) LCD, black required 6 percent more energy than white.

One of the most visible manifestations of the belief that black screens save energy is Blackle, an online search engine whose Web site is cast almost entirely in black. Created by Heap Media, Blackle exists "to remind people of the need to take small steps every day to save energy," says Blackle founder Toby Heap, who launched the site in January. "I do not expect the energy savings from Blackle to change the world on their own, but the point of Blackle is that every little bit counts."

One of the key arguments in favor of black screens is a 2002 research study produced by Lawrence Berkeley National Laboratory entitled "Energy Use and Power Levels in New Monitors and Personal Computers." The report indicates that "a given monitor requires more power to display a white (or light) screen than a black (or dark) screen." Indeed, that study reports that black screens consistently require less energy than white screens, regardless of whether the monitor is a CRT or LCD.

"It depends on the resting state of the LCD as to whether they require energy to stop light or to allow light to pass through," Heap explains. "This is why screen tests show that some CCFL (cold cathode fluorescent lamp) LCD screens save energy and some use a bit more. All of the scientific test data we have come across shows a slight saving on black LCD screens, which suggests that the rest state on many LCD screens does not allow light through." Heap also points out that a large number of Blackle users come from India and South America, where CRTs are still commonly sold.

Even though Google isn"t tied to Blackle other than powering its search engine, Google green energy czar Bill Weihl in August posted a blog disputing the notion of black as the new green. "We applaud the spirit of the idea, but our own analysis as well as that of others shows that making the Google homepage black will not reduce energy consumption," he wrote. "To the contrary, on flat-panel monitors (already estimated to be 75 percent of the market), displaying black may actually increase energy usage."

New advances in LCD technologies could eventually validate the belief that black is better. Newer types of LCD include a dynamic dimming capability that changes the strength of the backlight based on the image being displayed. Heap also points out that many of the new monitor technologies such as LCDs backlit with light-emitting diodes (LED), plasma screens and organic LED screens do not have a constant backlight "so we will see larger savings with Blackle as these new monitors replace the CCFL LCDs," he says.

In the meantime, the world is evenly split between CRT and LCD monitors, totaling roughly 405 million and 401 million respectively in 2007, according to iSuppli data. So if you"re still toiling away in front of a hefty CRT monitor that takes up three-quarters of your desk, then black screens will save you some energy. For those who"ve graduated to thinner LCD models, black screens are actually sucking up more energy then their white counterparts.

Before we get into the details of power consumption, let"s explain how we test for power consumption. We plug the TV into a Kill-A-Watt meter which measures the wattage. We display our checkerboard test pattern in SDR after calibration with local dimming disabled, and we record the power consumption. This is supposed to give an idea of everyday usage, but since everyone"s consumption is different, it"s simply an estimate. As for the max consumption, we set the TV in HDR with the checkerboard pattern, which sets the brightness to the max and enables local dimming, and we record the wattage in this situation.

Now that we have that out of the way, let"s talk about power consumption. Most modern TVs don"t take up much power as technologies such as LED and OLED have brought television power usages down a fair margin. Gone are the days of inefficient CRTs and plasma sets that could run up electricity costs by a good amount or even overheat.

Along with developments in technology that have allowed for more energy-efficient TVs, other new advances need more power, like HDR, which requires TVs to get brighter. Larger TV sizes are also becoming more popular, so they need more power than smaller TVs, even if they use the same technology. However, even then, TVs still don"t require a whole lot of power to function, and they won"t be burning a hole into your wallet when you get your utility bill.

TVs that require more power also get hotter. For most 4k TVs, this isn"t too much of a problem, but we"ve noticed 8k TVs get hot. If you have a TV that gets hot, it"s best to avoid placing it in a hot room and allow for good air ventilation around it. This shouldn"t be much of a problem in the winter because it may actually help heat your room, but you can end up spending more on air conditioning to cool it down in the summer. Then again, most 4k TVs won"t get hot enough to make a big difference in the winter or summer.

As you can see in this chart plotting TVs from 2016 and 2017, there"s a definite link between size and power consumption. Some features, such as full-array local dimming, are more costly, both to build and use. They require more LEDs than standard direct-lit and edge-lit type LCD TVs, but this isn"t represented in the chart. OLEDs have been consistently more power-hungry than the average LED models. In both cases, it"s not a ton of power, especially compared to older plasma TVs that often consumed twice as much as even the hungriest LEDs and OLEDs.

This chart above is a bit old now, so don"t look at the data points, but the trends still apply under our latest Test Bench 1.6 with 2020 and 2021 TVs. Out of our 4k TVs that we"ve tested, the TVs that require the most power in SDR are generally OLEDs. Seven of the ten most power-hungry TVs are OLEDs, and the three LEDs in the top 10 are 65, 75, and 85 inches. Larger TVs still require more power than smaller ones, which is expected. We noticed another trend with the Max Power Consumption: the 4k TVs that require the most power are also some of brightest, which are all LEDs. Even if you get an LED TV, it doesn"t mean it will need less power than OLED if you constantly watch HDR content at its max brightness.

Another trend we notice is that 8k TVs require a lot more power than 4k TVs. This makes sense because 8k TVs have four times the pixels as 4k TVs, so they need more energy to power. When testing 8k TVs at their max consumption power, they often get too hot to touch, which we rarely notice with 4k TVs.

Not only does consumption scale with size, but it also almost perfectly scales with brightness. As you can see above, raising your brightness from minimum progressively leads to higher consumption and inevitably higher costs. Reducing the brightness to the 50% setting instead of max doesn"t exactly halve the energy use, but that"s mostly because other parts of the TV also consume some energy.

Lower the backlight setting. The backlight is by far the biggest drain on your power, and the lower you can get your backlight, the less power your TV will consume. Placing your TV in a dark or dimly lit environment will help you avoid needing a bright backlight.

A lot of TVs have a “Quick Start” feature. This usually means that they stay in standby mode when you press the power button instead of shutting off completely. Turning these features off can help, but some models also allow you to hold the power button on the remote to shut down completely.

Most TVs today feature a light sensor that can adjust the TV"s brightness to the room. Instead of having the TV constantly run at a static brightness, this feature can help reduce consumption by lowering the brightness when it isn"t needed. However, some people may not enjoy this because it constantly changes the brightness.

If you often fall asleep in front of the TV at night, make use of its sleep timer feature. This greatly reduces consumption since you"re not leaving the TV on when you"re not watching it.

Power consumption varies from TV to TV and with the type of content you watch. However, there"s a trend that larger, brighter, and 8k TVs require the most power to function. OLEDs also tend to have slightly higher energy consumption than LEDs, but not if you"re using a bright LED TV and watching HDR content. You can use our power consumption calculator above to give you an estimate of how much you"ll be spending on electricity annually, but it all depends on the type of content you watch.

But which type of television is the best when it comes to energy use? The most common found in our living rooms are the traditional cathode-ray tube (CRT) sets, plasma, LED (Light Emitting Diode) and LCD (Liquid-Crystal Display). You might be shocked to find out that of these four, it is the CRT that is the energy hog— drawing more power per unit of screen area than the other three.

Research conducted by E Source, an energy efficiency and technology company, in 2011 compared a 55-inch of each style for five hours in active, or “on,” mode. The CRT set used a staggering 400 watts (W) followed distantly by the plasma and LCD sets at 165 W and finally by the LED at 155 W. The data also revealed that the same televisions in standby mode (when the television is turned off, but still plugged in and drawing some power) for 19 hours a day, the CRT drew 8 W compared to the LCD drawing .4 W. And a 25-inch CRT used more power than a 35-inch LCD at 95 W and 65 W respectively.

Many find this hard to believe, as it was plasma TVs having a reputation for being major energy drains. There was some justification to this in the past, when an average model drew more power than a CRT or LCD, but today’s plasma draws nearly the same power as a comparable LCD in sizes larger than 31 inches.

Why the jump in efficiency? The increased manufacture of larger, flat screen televisions left the CRT to be, in essence, phased out of the commercial market when production ceased in 2007. This left plasma, LCD and LED models to follow many sets of revised energy standards set by Energy Star and state regulations.

Another energy drain connected to our home’s TVs is the increased use of set-top box receivers. More than 80 percent of us subscribe to some form of pay television service with approximately 160 million set-top boxes (including DVRs), nearly all of which are owned and installed by cable, satellite or phone providers. NRDC found that in 2010, these boxes consumed 27 billion kilowatt-hours (kWh) of electricity, or the equivalent of the annual output of nine average (500 MW) coal-fired power plants. They also noted that two-thirds of their annual energy usage occurs when people are not even watching or recording content.

So what can you do to increase your TV’s energy efficiency? It may be a good idea to replace your CRT set for a more efficient model. Be sure to look for Energy Star ratings and read labels to estimate the annual energy consumption. If you already own an LCD TV, turn down the backlight in the television’s settings—you’ll save energy and still retain picture quality. Also, if you have TVs in multiple rooms and use a set-top box, consolidate to a multi-room model. And if your TV or box provides a power saver mode, use it or unplug both devices when you go out of town.

Widescreen displays (16:9)are now the norm and. Some standard/square screens offer good value and may be preferred if horizontal space is limited, but are now more common on laptop computers.

The most common resolution is 1920 x 1080, also known as 1080p. 1080p is an ideal resolution for monitors 21- to 24-inches. Higher resolutions may be preferred for larger screens.

Viewing angle:A measure of the angles a monitor can effectively be viewed at, expressed in degrees. This is not a major concern for the average seated computer user, but if you plan to share your screen with others -for example, to watch a video - look for something above 170 degrees.

Brightness:A bright screen is important if you"re working in a brightly lit room. A measure of how much light a monitor can emit, expressed in candelas per square meter (cd/m2). Besides simply looking better, a brighter monitor is much easier to see in brightly lit surroundings. Ratings of 250 to 300 cd/m2 are common for many affordable monitors.

LED backlighting:LED monitors are simply LCD monitors that use an LED backlight. LEDs allow manufacturers to make monitors slimmer, brighter, and without the warm-up time of traditional compact fluorescent (CFL) backlights.

Gloss or matte: Depending on the lighting of the room, screen coatings can be an important factor for overall viewing experience. Glossy screen coatings tend to enhance contrast for a more vibrant look, but also reflect their surroundings more readily when powered down or displaying dark images. Matte monitor displays tend to look more dull, but work better under challenging lighting conditions, like across from large windows.

Touch screen:Touch screen is a feature that can be utilized in conjunction with Windows 10, which incorporates many touch-screen features into its new interface. When purchasing, consider your at-home setup and how far back you sit from your monitor.

Monitors originally qualified for the ENERGY STAR label in 1992. The Version 8.0 ENERGY STAR Displays specification covers computer monitors and signage displays, including all products with touch screen functionality. ENERGY STAR certified computer monitors must meet a total energy consumption (TEC) requirement that takes in their power draw in On Mode and Sleep Mode and varies depending on screen area and resolution. Signage displays must draw 0.5 watts or less in Sleep Mode and Off Mode, while On Mode power requirements vary according to screen area and resolution. Additional TEC and power allowances are also provided for select features. External power supplies (EPS) packaged with displays must meet level VI performance requirements under the International Efficiency Marking Protocol and include the level VI marking.

Do you need a display that draws the lowest current possible? Want long lasting battery-powered LCD project? Well, you have come to the right place. We compiled this list of digital displays that consume the least amount of power. These displays are perfect for when you are trying to extend the battery life of your product by pulling the least amount of current possible.

Other than a pen and paper, ePaper provides the lowest power consumption available for electronic displays. It does this via an electrochemical process that requires zero power once the pixels are in their desired location. These displays are ideal for when the content is not updated very often. Low-power ePapers only use power during updates, so the longer time between updates, the lower the power consumed.

The beauty of OLED displays and power consumption is that OLEDs only draw current for pixels that are on. For instance, when displaying a black and white checkerboard pattern, an OLED display consumes 50% less current than when displaying a completely white screen. Keeping that in mind, user interfaces can be designed to conserve as much power as possible by limiting how many pixels are lit.
