These features effectively lower the total cost of ownership and enhance the return on investment over the long term, making them an excellent choice for corporate display solutions.
Why Are Energy-Efficient LED Screens More Energy-Efficient Than Conventional LED Screens?
Low-Power LEDs
Energy-efficient LED screens utilize low-power LEDs with a different structure than conventional LED screens. These LEDs differ from conventional LEDs in terms of internal structure, materials used, and size.
Within the same screen structure, low-power LEDs can produce the same brightness as conventional LEDs using less power, thereby effectively reducing energy consumption.
Common-Cathode Circuit Design
Compared to the common-anode technology used in traditional LED displays, which rely on a single 5V DC power supply, the common-cathode circuit in energy-efficient LED displays effectively mitigates the issues of excessive heat loss and energy waste caused by excessively high voltages in common-anode circuits.
The common cathode LED circuit system employs a dual-voltage power supply design, which independently provides more precise voltages for each red, green, and blue LED (for example, approximately 2.8V for red LEDs and approximately 3.8V for green and blue LEDs).
This significantly reduces power loss and heat generation while ensuring the normal operation of the LED display and maintaining image quality.
In outdoor settings with direct sunlight, LED displays using common-cathode technology can still maintain a balanced internal temperature, making them well-suited for applications requiring sustained high brightness outdoors over extended periods.
High-Efficiency Power Supply
The LEDs used in LED displays can convert approximately 50% of electrical energy into light radiation, achieving a much higher energy utilization rate than other lighting devices.
At the same time, advanced PWM driver ICs distribute power precisely to optimize energy usage. When displaying static images, power consumption is even lower, allowing for further energy savings without compromising visual quality.
Upgraded Packaging Technology
Some energy-efficient LED displays utilize the flip-chip COB packaging technology, which involves soldering the LED chips directly onto the PCB.
By eliminating the traditional supports and circuit structures found in SMD technology, thermal resistance is reduced, thereby enhancing heat dissipation performance.
Superior heat dissipation effectively lowers junction temperature and reduces the likelihood of LED screen failures, thereby significantly extending the screen’s service life.
Superior Heat Dissipation Design
For LED cabinets, most indoor and outdoor rental screens, as well as all standard indoor LED screens, do not require additional cooling equipment.
However, certain large outdoor screens, as well as those located in hot regions and exposed to prolonged direct sunlight, require cooling equipment such as fans or air conditioners installed within the LED cabinets.
Compared to the standard LED displays described above, energy-efficient LED displays feature LED cabinets with superior ventilation designs or all-die-cast aluminum heat dissipation structures.
This enables more efficient heat dissipation, reduces the need for cooling equipment, and consequently minimizes the additional energy consumption caused by such equipment.
Intelligent Brightness Adjustment
When equipped with light sensors, energy-efficient LED displays combine brightness adjustment with artificial intelligence through an integrated smart system to enable real-time dynamic output adjustment.
In well-lit environments, the system increases brightness to maintain image visibility; at night, when ambient light is low, it reduces brightness to conserve energy and prevent glare.
In addition, the intelligent system comprehensively evaluates and adjusts settings based on factors such as the nature of the displayed content (motion, brightness, etc.), the duration of daily operation, and variations in content across different time periods, ensuring the display’s energy consumption is maintained at an optimal level.
Specific Applications of Energy-Efficient LED Screens
Commercial Advertising Displays
Whether it’s large outdoor digital ads or indoor shopping mall displays, LED screens need to run for long periods, so operating costs become a key consideration.
Energy-saving LED screens not only deliver clear and vivid visuals to the audience but also effectively reduce operating costs.
For outdoor large-screen ads, using energy-saving screens made with common-cathode circuit technology can achieve even better energy efficiency.
Public Facility Displays
For LED screens in high-speed rail stations, airports, and subway stations—where information must be displayed for extended periods—using energy-efficient LED screens can effectively reduce energy consumption and operating costs while ensuring excellent image quality, clearly legible text, and effective information dissemination.
Sports Event Displays
Large LED scoreboards, live match broadcast screens, or circular LED displays in stadiums and arenas are typically installed for long-term, fixed use.
The robust design of energy-efficient LED displays effectively reduces the likelihood of screen failures, thereby lowering the cost and complexity of future maintenance.
Surveillance System Applications
In surveillance systems such as security rooms and dispatch centers, LED displays must operate 24 hours a day without interruption. It is essential to ensure the clarity of the images displayed to guarantee the reliability and stability of real-time monitoring.
Applications in the Education Sector
Some universities use energy-efficient LED displays as bulletin boards, billboards, or event promotion boards. This aligns with the schools’ environmental philosophy and promotes the development of green campuses.
How Much Energy Can Energy-Efficient LED Displays Save?
We compare JYLED’s energy-efficient LED displays with standard LED displays.
Taking a 50 square meter P10 outdoor display as an example (operating 10 hours per day, 365 days per year):
Energy-efficient LED display:
- Average power consumption: 0.18 kW/㎡
- Annual energy consumption: 0.18 (kW/㎡) × 50 (㎡) × 10 (h) × 365 (days) = 32,850 (kWh)
Conventional LED Display:
- Average power consumption: 0.275 kW/m²
- Annual energy consumption: 0.275 (kW/m²) × 50 (㎡) × 10 (h) × 365 (days) = 50,187.5 (kWh)
- Energy savings: 50,187.5 – 32,850 = 17,337.5 kWh.
Based on the average U.S. commercial electricity rate of $0.08/kWh, using an energy-efficient LED display can save $1,387 in electricity costs annually.
- Using the formula: 17,337.5 ÷ 50,187.5 × 100% ≈ 35%
We can conclude that energy-efficient LED displays save 35% more energy compared to standard LED displays.
When Is It Appropriate to Choose an Energy-Efficient LED Display?
Although energy-efficient LED displays can be applied in many scenarios, they are most suitable for the following three specific situations:
Screens Requiring 24-Hour Continuous Operation
When LED displays are used in monitoring rooms, data monitoring centers, and other surveillance systems that require 24-hour continuous operation, energy-efficient LED displays should be considered.
Their superior heat dissipation performance not only prevents overheating and premature aging but also ensures the display can operate normally for extended periods.
Over extended periods of use, energy-efficient screens can effectively conserve electricity and reduce electricity costs compared to standard LED screens.
Large-Area Display Requirements
For scenarios requiring large LED screens—such as major concerts, stadiums, and sports arenas—energy-efficient LED screens are often the better choice.
Among screens with the same structure and energy-saving ratio, the amount of energy saved is closely related to the screen’s size.
Larger screens result in greater cost savings, especially for permanently installed large screens used over the long term, where lower costs often lead to a higher return on investment.
