Outdoor LED displays are becoming increasingly prevalent in applications like advertising and public information dissemination. For operators, electricity costs are a primary concern. Currently, outdoor LED displays are broadly categorized into energy-efficient and conventional versions. The conventional version, due to its mature technology and wide range of applications, dominates the market and is the choice for most users. Therefore, our electricity cost analysis will focus on these conventional models.

Generally, the power consumption of an outdoor LED display is directly proportional to its brightness, a characteristic determined by its display technology. Conventional outdoor LED displays typically maintain a brightness range of 5500 to 8000 CD per square meter. This brightness ensures clear visibility even in strong light conditions and directly impacts power consumption, with a corresponding maximum power draw per square meter ranging from 750W to 1200W. However, in actual use, full-color LED displays continuously play dynamic content, leading to a significantly higher utilization rate than traditional monochrome or dual-color screens. Consequently, their actual operating power is lower than the maximum consumption, typically stabilizing between 400W and 700W per square meter under normal conditions.

Using China's industrial electricity price as an example (approximately 0.8 RMB per kilowatt-hour), we can clearly calculate daily electricity costs.

Conventional Display (per square meter):

At an average power of 400W, daily consumption (based on 10 hours of typical use) is 4 kWh, costing 3.2 RMB.

If the power reaches 700W, daily consumption is 7 kWh, increasing the cost to 5.6 RMB.

Energy-Efficient Display (per square meter):

With a power consumption of approximately 150W per square meter, daily consumption is 1.5 kWh, costing 1.2 RMB.

In summary, the daily electricity cost per square meter for an outdoor LED display ranges from 1.2 RMB to 5.6 RMB.

Extrapolating this to monthly costs, based on 30 days per month, the minimum monthly electricity cost per square meter is 1.2 RMB × 30 days = 36 RMB, and the maximum is 5.6 RMB × 30 days = 168 RMB. This cost range provides operators with a more precise estimate of long-term operating expenses when planning outdoor LED display projects, offering reliable data for budget formulation.
