For most users, the most direct way to determine whether an LED display is "power-hungry" is to calculate: how much electricity does it consume per square meter per day? What is the daily electricity cost?
Basic Calculation Method for LED Display Power Consumption
Daily power consumption (kWh) = Screen area (square meters) × Average power consumption (watts/square meter) × Usage time (hours) ÷ 1000
Note: LED displays have two power consumption values.
Maximum power consumption refers to the extremely high power consumption when the screen is fully lit and completely white (uncommon).
Average power consumption is closer to actual daily use and is generally 30%-50% of the maximum power consumption.
How to calculate the power consumption of an LED wall?
If you want to calculate the energy consumption of a P2.5 full-color indoor conference room LED screen with an area of 3 square meters (approximately 2.4 meters × 1.25 meters), assuming it is used for 8 hours a day. Assuming the average power consumption is 300W/㎡ (industry reference value), the calculation is as follows: 3 × 300 × 8 ÷ 1000 = 7.2 (kWh)
For a 5㎡ indoor shopping mall advertising LED screen with an average power consumption of 350W/㎡ and a pixel pitch of P4, assuming 8 hours of daily use, the energy consumption calculation is: 5 × 350 × 8 ÷ 1000 = 14 kWh
For a 10㎡ full-color outdoor LED large screen with an average power consumption of 500W/㎡ and a pixel pitch of P5, assuming 8 hours of daily use, the energy consumption calculation is: 10 × 500 × 8 ÷ 1000 = 40 kWh
