lcd screen power consumption pricelist

The power consumption of computer or tv displays vary significantly based on the display technology used, manufacturer and build quality, the size of the screen, what the display is showing (static versus moving images), brightness of the screen and if power saving settings are activated.

Click calculate to find the energy consumption of a 22 inch LED-backlit LCD display using 30 Watts for 5 hours a day @ $0.10 per kWh. Check the table below and modify the calculator fields if needed to fit your display.

Hours Used Per Day: Enter how many hours the device is being used on average per day, if the power consumption is lower than 1 hour per day enter as a decimal. (For example: 30 minutes per day is 0.5)

LED & LCD screens use the same TFT LCD (thin film transistor liquid crystal display) technology for displaying images on the screen, when a product mentions LED it is referring to the backlighting. Older LCD monitors used CCFL (cold cathode fluorescent) backlighting which is generally 20-30% less power efficient compared to LED-backlit LCD displays.

The issue in accurately calculating the energy consumption of your tv or computer display comes down to the build quality of the screen, energy saving features which are enabled and your usage patterns. The only method to accurately calculate the energy usage of a specific model is to use a special device known as an electricity usage monitor or a power meter. This device plugs into a power socket and then your device is plugged into it, electricity use can then be accurately monitored. If you are serious about precisely calculating your energy use, this product is inexpensive and will help you determine your exact electricity costs per each device.

In general we recommend LED displays because they offer the best power savings and are becoming more cheaper. Choose a display size which you are comfortable with and make sure to properly calibrate your display to reduce power use. Enable energy saving features, lower brightness and make sure the monitor goes into sleep mode after 5 or 10 minutes of inactivity. Some research studies also suggest that setting your system themes to a darker color may help reduce energy cost, as less energy is used to light the screen. Also keep in mind that most display will draw 0.1 to 3 watts of power even if they are turned off or in sleep mode, unplugging the screen if you are away for extended periods of time may also help.

Many appliances continue to draw a small amount of stand-by power when they are switched "off." These "phantom loads" occur in most appliances that use electricity, such as televisions, stereos, computers, and kitchen appliances. Most phantom loads will increase the appliance"s energy consumption a few watt-hours, and you can use a monitor to estimate those too. These loads can be avoided by unplugging the appliance or using a power strip and using the switch on the power strip to cut all power to the appliance.

I’m hearing from some industry friends that LCD display panel prices are rising – which on the surface likely seems incongruous, given the economic slowdown and widespread indications that a lot of 2020 and 2021 display projects went on hold because of COVID-19.

On the other hand, people are watching a lot more TV, and I saw a guy at Costco the other day with two big-ass LCD TVs on his trolley. And a whole bunch of desktop monitors were in demand in 2020 to facilitate Work From Home. So demand for LCD displays is up outside of commercial purposes.

The Korean business portal BusinessKorea says one explanation was a power outage that shut down a big glass substrate factory in Japan, which was serious enough that the plant will only get back to normal sometime in this quarter.

Continuing strong demand and concerns about a glass shortage resulting from NEG’s power outage have led to a continuing increase in LCD TV panel prices in Q1. Announcements by the Korean panel makers that they will maintain production of LCDs and delay their planned shutdown of LCD lines has not prevented prices from continuing to rise.

Panel prices increased more than 20% for selected TV sizes in Q3 2020 compared to Q2, and by 27% in Q4 2020 compared to Q3, and we now expect that average LCD TV panel prices in Q1 2021 will increase by another 9%.

If you are looking for a new display, you should consider the differences between CRT and LCD monitors. Choose the type of monitor that best serves your specific needs, the typical applications you use, and your budget.

Require less power - Power consumption varies greatly with different technologies. CRT displays are somewhat power-hungry, at about 100 watts for a typical 19-inch display. The average is about 45 watts for a 19-inch LCD display. LCDs also produce less heat.

Smaller and weigh less - An LCD monitor is significantly thinner and lighter than a CRT monitor, typically weighing less than half as much. In addition, you can mount an LCD on an arm or a wall, which also takes up less desktop space.

More adjustable - LCD displays are much more adjustable than CRT displays. With LCDs, you can adjust the tilt, height, swivel, and orientation from horizontal to vertical mode. As noted previously, you can also mount them on the wall or on an arm.

Less eye strain - Because LCD displays turn each pixel off individually, they do not produce a flicker like CRT displays do. In addition, LCD displays do a better job of displaying text compared with CRT displays.

Better color representation - CRT displays have historically represented colors and different gradations of color more accurately than LCD displays. However, LCD displays are gaining ground in this area, especially with higher-end models that include color-calibration technology.

More responsive - Historically, CRT monitors have had fewer problems with ghosting and blurring because they redrew the screen image faster than LCD monitors. Again, LCD manufacturers are improving on this with displays that have faster response times than they did in the past.

Multiple resolutions - If you need to change your display"s resolution for different applications, you are better off with a CRT monitor because LCD monitors don"t handle multiple resolutions as well.

So now that you know about LCD and CRT monitors, let"s talk about how you can use two monitors at once. They say, "Two heads are better than one." Maybe the same is true of monitors!

For small/medium size televisions, LCD is clearly the choice for those of you with limited power. The other great news is that they are getting cheaper as time goes on. Coles and a number of supermarkets are now selling 38 cm LCD televisions for under AUS$200.

I say "if" because they are designed to run off a 230V-12V regulated power supply. This is not the same as running it direct from a 12V solar system where the battery voltage can easily range from 11 to 15 volts. An even wider variance is possible with flat or failing batteries; a battery system being equalised to 15.5-16 volts etc.

There appears to be a few brands that can definitely be run off a battery and these are marketed to the caravan and yachting market. Majestic LCD televisions will operate between 10.9 and 15.5 volts. Xien sell a range for the marine industry. Sharp televisions are also sold as "12 volts" but come with a $140 special 12 V lead. I suggest this has a power conditioner on it. Dick Smith once sold (and may still do so) an AC/DC 15 inch model.

The power "saving" of being able to run it direct is significant. From my observations, the 230 to 12V adapter supplied with the television is only about 50% efficient. By the time you then use an inverter to change your 12V to 230V, I estimate that you could be tripling your power consumption.

For the "big end of town", a consumer magazine tested 4 popular brands of large LCD and Plasma televisions for power consumption. Interestingly, the 45/ 46 inch Plasma televisions used 260 –286 watts while the 42/43 inch Plasma televisions used significantly less (183- 186 watts). All four used between 0.67 and 1.4 watts on stand by.

It has to do with yields and the production costs. It is far easier to make a PERFECT four inch display than an eight inch display, just because there is a smaller chance of dead or stuck pixels. As the size of the screen goes up, it just becomes that much harder to make a display without any problems.

When you tune in to the 6pm news at night, do you ever stop to think “what’s this costing me?” Nothing, right? It’s free TV after all. Unfortunately, that’s not quite true as televisions can be notorious power guzzlers and a lot of us overlook just how much it adds to our electricity bills.

The table below estimates how much the common LED LCD TV costs per hour to watch, factoring in its size and energy efficiency star rating. The table uses data collected and assumes a usage rate of 33c/kWh. Keep in mind that electricity rates will vary between states and providers.

A TV in standby mode costs around 0.02c to 0.1c per hour, which is not nearly as much as some other appliances. This will again vary depending on the model of the television and the rate you’re paying for electricity. You can check the standby wattage in the TV manual or on the label attached to the cord, but generally speaking, leaving your television on standby won’t blow out the budget. Be sure to check out our article on standby electricity for a closer look at how it is adding to your power bill.

LED LCD: LCD’s work using liquid-crystal (LCD) display lit up by an LED backlight. These televisions are generally considered to be the most energy efficient.

OLED: Organic Light Emitting Diode (OLED) televisions do not require an LED backlight which allows for deeper shading and colouring. Regardless, they have a similar energy efficiency as LED LCD televisions.

Screen brightness: Brighter lights require more electricity, the same goes for televisions. Higher brightness settings means the TV consumes more energy, adding to the bill.

Volume: The volume of your television admittedly contributes an incredible miniscule amount to your TV’s electricity consumption, except where you’re blasting it at maximum volume. It all adds up though and having an unnecessarily loud TV might cost you.

3-D TV: 3-D technology requires a complicated array of colours on screen. Processing these images requires the TV to work a little harder, pushing up the energy bill.

Hisense is a multinational white goods and electronics manufacturer based in China. Its range typically rivals other leading brands on colour and picture quality, and often comes cheaper than other high-end brands out there. The 32” LED LCD model from Hisense provides a 6-star energy efficiency rating, with a recommended retail price tag of $449. It uses 104kWh per annum, which according to the Standard Test (based on 29c/kWh), should cost you around $30 to use this each year.

The brand that says ‘Life’s good’ is perhaps best known for its big ticket home electronics, including televisions. If you’re considering a large TV option, you might like to consider the LG 65” LED LCD model with the same 6-star energy efficiency rating. With the additional screen size, it would use 307kWh each year, giving you an annual running cost of around $89, based on 29c/kWh. With additional features, it ranks up a price tag of $2,999RRP.

Samsung is another leading TV manufacturer, offering both high-end and budget TV options. Samsung’s 6-star TV in terms of energy efficiency is the 24” LED LCD model. In a similar price range as the Hisense option mentioned above, this Samsung TV sells for about $450 on Appliances Online. It uses 66kWh of energy per year and in turn will cost just $20 or so to run.

Sony is a multinational Japanese company with a modest television range. It also offers a 6-star energy efficient TV – the Sony 43” HDR LED model. It sits in the mid-range in terms of screen size and boasts a number of features. The Sony TV uses 160kWh of energy each year, adding about $47 to your electricity bill. In terms of upfront costs, it currently sits at $899 on Appliances Online.

Rounding of our list of most energy efficient TVs you can buy is TCL that has an extensive range of TV’s available in Australia. The Chinese brand offers a large 65” LED LCD model with a 6-star energy efficiency rating, similar to the brands mentioned above. It has a total energy usage of 350kWh/year and you can expect an additional $101 on your annual power bill. This appliance will set you back $2,999 with its upfront cost.

There are plenty of new and confusing terms facing TV shoppers today, but when it comes down to the screen technology itself, there are only two: Nearly every TV sold today is either LCD or OLED.

The biggest between the two is in how they work. With OLED, each pixel provides its own illumination so there"s no separate backlight. With an LCD TV, all of the pixels are illuminated by an LED backlight. That difference leads to all kinds of picture quality effects, some of which favor LCD, but most of which benefit OLED.

LCDs are made by a number of companies across Asia. All current OLED TVs are built by LG Display, though companies like Sony and Vizio buy OLED panels from LG and then use their own electronics and aesthetic design.

So which one is better? Read on for their strengths and weaknesses. In general we"ll be comparing OLED to the best (read: most expensive) LCD has to offer, mainly because there"s no such thing as a cheap OLED TV (yet).

The better LCDs have local dimming, where parts of the screen can dim independently of others. This isn"t quite as good as per-pixel control because the black areas still aren"t absolutely black, but it"s better than nothing. The best LCDs have full-array local dimming, which provides even finer control over the contrast of what"s onscreen -- but even they can suffer from "blooming," where a bright area spoils the black of an adjacent dark area.

One of the main downsides of LCD TVs is a change in picture quality if you sit away from dead center (as in, off to the sides). How much this matters to you certainly depends on your seating arrangement, but also on how much you love your loved ones.

A few LCDs use in-plane switching (IPS) panels, which have better off-axis picture quality than other kinds of LCDs, but don"t look as good as other LCDs straight on (primarily due to a lower contrast ratio).

OLED doesn"t have the off-axis issue LCDs have; its image looks basically the same, even from extreme angles. So if you have a wide seating area, OLED is the better option.

Nearly all current TVs are HDR compatible, but that"s not the entire story. Just because a TV claims HDR compatibility doesn"t mean it can accurately display HDR content. All OLED TVs have the dynamic range to take advantage of HDR, but lower-priced LCDs, especially those without local-dimming backlights, do not. So if you want to see HDR content it all its dynamic, vibrant beauty, go for OLED or an LCD with local dimming.

In our tests comparing the best new OLED and LCD TVs with HDR games and movies, OLED usually looks better. Its superior contrast and lack of blooming win the day despite LCD"s brightness advantage. In other words LCD TVs can get brighter, especially in full-screen bright scenes and HDR highlights, but none of them can control that illumination as precisely as an OLED TV.

OLED"s energy consumption is directly related to screen brightness. The brighter the screen, the more power it draws. It even varies with content. A dark movie will require less power than a hockey game or ski competition.

The energy consumption of LCD varies depending on the backlight setting. The lower the backlight, the lower the power consumption. A basic LED LCD with its backlight set low will draw less power than OLED.

LG has said their OLED TVs have a lifespan of 100,000 hours to half brightness, a figure that"s similar to LED LCDs. Generally speaking, all modern TVs are quite reliable.

Does that mean your new LCD or OLED will last for several decades like your parent"s last CRT (like the one pictured). Probably not, but then, why would you want it to? A 42-inch flat panel cost $14,000 in the late 90"s, and now a 65-inch TV with more than 16x the resolution and a million times better contrast ratio costs $1,400. Which is to say, by the time you"ll want/need to replace it, there will be something even better than what"s available now, for less money.

OLED TVs are available in sizes from 48 to 88 inches, but LCD TVs come in smaller and larger sizes than that -- with many more choices in between -- so LCD wins. At the high end of the size scale, however, the biggest "TVs" don"t use either technology.

You can get 4K resolution, 50-inch LCDs for around $400 -- or half that on sale. It"s going to be a long time before OLEDs are that price, but they have come down considerably.

LCD dominates the market because it"s cheap to manufacture and delivers good enough picture quality for just about everybody. But according to reviews at CNET and elsewhere, OLED wins for overall picture quality, largely due to the incredible contrast ratio. The price difference isn"t as severe as it used to be, and in the mid- to high-end of the market, there are lots of options.
