Maximum connected load is important for electrical design, but it is not the same as average operating consumption.

Real load changes with brightness settings, image content, day/night scheduling and control strategy. Buyers should therefore ask for both maximum design load and a realistic operating estimate based on the intended use.

Standard 5V architecture remains common in LED displays. JYVISIONS also develops energy-saving outdoor configurations that use separate lower-voltage rails for red and blue/green channels according to the selected LED/circuit design.

The purpose is to supply parts of the LED system closer to the voltage they actually require instead of dissipating unnecessary electrical energy as heat.

Electrical energy that is not converted into useful light ultimately contributes to heat inside the module and cabinet.

Reducing unnecessary voltage loss can therefore reduce thermal load as well as electricity use. This does not mean every lower-voltage product automatically runs cooler under every condition; brightness, ambient temperature, ventilation, cabinet design and component efficiency still matter.

An outdoor screen may need high peak brightness for direct sun but much less output at night or in lower ambient light.

Automatic or scheduled dimming can reduce unnecessary power use while improving nighttime viewing comfort. Brightness strategy should be designed together with energy architecture rather than treated as a separate setting after installation.

Energy-saving architecture has more commercial impact on a large screen operating 16–24 hours per day than on a small screen used occasionally.

Evaluate screen area, expected average load, local electricity price and annual operating hours together. The correct comparison is project OPEX over time, not only the initial cabinet price.

JYVISIONS internal engineering estimates can show large differences between standard and energy-saving configurations in some cases, but the exact result depends on product architecture, brightness, content and test conditions.

For public website claims and quotations, use measured data from the actual model or project configuration. Do not apply one universal saving percentage to all outdoor LED screens.

Ask for maximum power, estimated average power, assumed brightness level, operating hours, voltage architecture, power-supply configuration, cabinet/module design and the conditions used for any energy comparison.

This creates a much more useful procurement comparison than a single ‘energy saving’ label.

Conventional outdoor LED commonly uses a 5V or approximately 4.5V common-anode supply architecture. A split-voltage common-cathode design can supply red and blue/green channels closer to their real forward-voltage requirements, but the exact voltage choice changes the engineering difficulty.

JYVISIONS commonly works with practical split-voltage combinations around 3.2V for red and 4.0–4.2V for blue/green. More aggressive combinations closer to approximately 2.8V for red and 3.8V for blue/green can reduce electrical loss further, but they require tighter LED Vf binning, PCB voltage-drop control, connector and cable-loss control, power-supply accuracy and overall system matching. If those variables are not controlled, brightness or white-point consistency can suffer.

JYVISIONS compared several outdoor P8/P10 voltage architectures under a controlled engineering test at approximately 35°C ambient temperature, direct solar exposure, full-white output and natural heat dissipation in a die-cast aluminum cabinet. In that test setup, the conventional 5V common-anode configuration measured approximately 62–70°C, while a 2.8V + 3.8V split-voltage configuration measured approximately 46–53°C. A 3.2V + 4.0V configuration measured approximately 49–56°C, and a 3.2V + 4.2V configuration measured approximately 52–60°C.

Under the same comparison framework, measured electrical reduction relative to the 5V common-anode condition was approximately 25–34% for 2.8V + 3.8V, 20–25% for 3.2V + 4.0V and 17–24% for 3.2V + 4.2V. These are configuration-specific test results, not universal savings claims. Actual power and temperature change with ambient temperature, solar load, brightness, content, LED/IC selection, cabinet construction and airflow.

JYVISIONS is more likely to recommend an energy-saving architecture for commercial screens that operate for many hours per day and for high-brightness projects in the 8,000–10,000-nit class, because electrical efficiency and heat become increasingly important together.

If a screen is shaded, operates at moderate brightness, runs only a limited number of hours per day and has a strict initial budget, a conventional architecture can still be a rational choice. The correct decision is a project-level trade-off rather than a rule that every outdoor screen must use the most aggressive voltage split.

On the website, JYVISIONS leads with Diamond and AP for energy-saving outdoor projects. FO can also be engineered with energy-saving electrical options when a project specifically requires them, but FO is not positioned as the primary public energy-saving route.

Diamond Series outdoor LED display is a primary JYVISIONS energy-saving outdoor platform when the project requires a mature integrated fixed-installation architecture.

AP Series outdoor LED display is also a primary energy-saving route, particularly where finer pixel pitch or more cabinet-format choices are required.

Energy saving is not only a power-supply or common-cathode decision. JYVISIONS also recommends ambient-light sensing and automatic brightness adjustment for many outdoor installations. When full brightness is unnecessary, reducing LED output lowers electrical consumption and heat generation. Lower thermal load can reduce operating temperature and thermal stress, supporting longer-term performance of LEDs, driver ICs and power components. Any percentage-saving claim must still be tied to the actual voltage architecture, brightness level, content, ambient condition and test method.
