lcd displays energy 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.

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.

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.

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%.
