Under the dual pressures of the global climate crisis and energy transformation, energy conservation and emission reduction have evolved from corporate social responsibility to the core track of commercial competition. As an important part of the urban visual ecology, the outdoor advertising industry consumes hundreds of millions of electric energy every year.

According to statistics from the International Energy Agency, the energy consumption of traditional outdoor LED display screens accounts for more than 60% of the total electricity consumption of commercial advertising equipment. The  dynamic outdoor energy-saving LED screen launched by SightLED is rewriting the rules of the industry. We will reveal to you why you need to choose an energy-saving outdoor LED advertising screen.

Why do you need an outdoor energy-saving  LED screen?

Reduce Energy consumption costs

Take a 100㎡ LED screen as an example. The annual power consumption of a conventional screen is about 150,000 kWh (calculated at 18 hours/day), while the Sight LED energy-saving LED screen can reduce energy consumption to less than 80,000 kWh through a triple technology matrix.

Calculated at an industrial electricity price of 1 yuan/kWh, a single LED screen saves more than 70,000 yuan in electricity bills each year, which is equivalent to a direct halving of the operating costs of conventional screens.

Cooling system optimization

The traditional common anode solution causes more than 30% of electrical energy to be converted into heat energy due to voltage waste. In adition,you also need high-power cooling equipment. Our dynamic energy-saving LED screen reduces heat generation by 45% and cooling system energy consumption by 60% through precise power supply technology. Therefore, it can extend the life of the equipment by 2-3 years in tropical areas.

Reduce light pollution

When our energy-saving outdoor  screen is integrated with an intelligent light sensing system, the screen brightness can be dynamically adjusted between 5000-12000cd/㎡.

In the morning, the LED screen can automatically reduce the brightness by 40% to maintain a clear display. At noon, the contrast can be intelligently enhanced. At night, it switches to a cinema-level soft light mode. Compared with the fixed brightness solution of conventional screens, they can reduce light pollution and extend the life of lamp beads.

More cost-effective

Although the initial purchase cost of energy-saving LED screens is higher, the total cost of ownership of energy-saving screens in 5 years has significant advantages:

• Electricity bill savings: 350,000-500,000 yuan
• Reduced maintenance costs: Modular design shortens fault repair time by 70%
• Increased residual value: Second-hand equipment recycling premium reaches 20%

You can see that outdoor energy-saving LED display screens have such huge advantages, so how does SightLED do it?

SightLED common cathode technology outdoor LED display principle

Dynamic power supply

The traditional common cathode solution roughly adopts 5V unified power supply, resulting in 2.8V redundant voltage for red tubes and 1.8V redundant voltage for blue and green tubes, with an overall energy efficiency loss of 35%.

The common cathode architecture of SightLED realizes 1.9-2.2V power supply for red tubes (accuracy ±0.05V) and 2.9-3.2V power supply for blue and green tubes (accuracy ±0.1V). Through the real-time voltage compensation algorithm, each lamp bead can work at the optimal efficiency curve point.

Power management optimization:

We use the third-generation GaN (gallium nitride) power chip, which can achieve:

• Conversion efficiency 98.5% (conventional solution ≤ 90%)
• Ripple factor <1% (industry standard is 5%)
• Dynamic response time 0.2ms (15 times faster than conventional solutions).

In addition, with PWM-AM hybrid dimming technology, when displaying dark scenes, our LED screen can automatically switch to the current micro-amplitude mode, reducing the power consumption of low grayscale scenes by 60%.

Advanced light sensing system

Equipped with Sight LED’s self-developed light sensing system, our outdoor energy-saving screen can achieve:

• 1024-level brightness adaptive adjustment
• Ambient illumination perception accuracy ±5Lux
• Support sunrise/sunset algorithm prediction (optional)
• Automatically enhance color saturation in rainy weather (optional)
• Start penetration enhancement mode in haze environment

Therefore, they can truly achieve the perfect balance of “seeing clearly” and “saving a lot”.

Outdoor energy-saving LED display vs. outdoor conventional LED display

Defects of outdoor conventional screens

Unreasonable power supply method

Conventional outdoor screens use common anode power supply and are uniformly powered by 5V. Therefore, some lamp beads receive voltages that exceed actual requirements. Excess electrical energy is converted into heat energy, increasing unnecessary energy consumption.

Serious heat dissipation problem

Due to excessive energy consumption, the surface temperature of the LED display is high, which can easily lead to aging of electronic components and increase maintenance costs.

Single brightness adjustment

The traditional screen brightness adjustment method is relatively simple, and it cannot achieve the best display effect under different lighting environments, while increasing energy consumption.

Advantages of our energy-saving outdoor  LED screens

Efficient energy saving and reduced energy consumption

Through precise power supply and intelligent power management, energy-saving LED screens can reduce energy consumption by 30%-50% compared to traditional LED screens, helping users reduce electricity bills.

Increase equipment life

Through precise power supply, reduce the conversion of electrical energy into heat, thereby reducing screen temperature, increasing the life of LED lamp beads and electronic components, and reducing maintenance costs.

Intelligent adjustment

Equipped with an intelligent light sensing system, it can automatically adjust the brightness according to ambient light. Reduce energy waste caused by excessive brightness while ensuring clear images.

Subvert cognitive display performance

• Brightness control: supports 0-12000cd/㎡ infinite adjustment, 200% more than the 3000-8000cd/㎡ range of conventional screens.
• Color gamut coverage: NTSC 112% (conventional screen is 85%).
• Contrast ratio: 8000:1 (conventional screen 3000:1).
• Grayscale performance: 16bit processing capability (conventional screen 14bit).
• Modular hard connection design makes single module replacement time <5 minutes.

Comparison of energy consumption costs

Let us take a 100㎡ screen of P3 specification as an example

Cost comparison between energy-saving outdoor LED screen and conventional LED screen

Life cycle cost model (5 years)

Energy-saving screen saves 1.038 million yuan in 5 years, and the return on investment period is only 11 months.

Hidden costs of conventional LED screens

• The PCB deformation rate of conventional screens due to insufficient heat dissipation is as high as 12%.
• The annual incidence of driver IC damage caused by unstable voltage is 8%.
• The high heating environment shortens the life of the power system by 30%.
