But if you are concerned about the amount of power your LED screens consume and want to know how to save some energy and spend on operation, you are right about being on this page.

We discuss below everything you need to know about LED screen power consumption (power indicators, tips, and other factors that may affect your power use).


3. Power Consumption Indicators of an LED Screen


  • Maximum Power Consumption
Light-emitting Diodes
Light-emitting Diodes

The light-emitting diodes integrated into the LED panels are responsible for producing the colorful images on the screen monitor. These semiconductor light sources emit light in different intensities and colors depending on the source input you use. It means that when an input source requires an LED screen to display a full black paint on the screen, the diodes will not light up at all.

On the other hand, to show a full white color on the screen, all light-emitting diodes will light up and work at their maximum level. The maximum power consumption refers to a display situation that makes the diodes work at full power. In other words, the diodes are set to produce light brightness to its optimum level.  The amount of power or energy consumed in such a case equates to the maximum power consumption of your LED wall unit, with a small margin for other environmental variables.


  • Black Level Power Consumption

This type of power consumption refers to the amount of energy being utilized by your LED screen to display “nothing” on the LED wall monitor. You may think that since no light is used when displaying blank content, no amount of power is also being used. However, even though the diodes are off, other LED screen components like the LED drivers and receiving cards are still functioning and consuming energy.


  • Standby Power Consumption

Standby mode, alternatively known as sleep mode, is a function in almost all electronic devices that help conserve power consumption when your LED screen is not in use without totally powering the hardware off. Usually, when any device has become idle for a certain period, it temporarily disables some hardware features that consume energy.

Standby power consumption refers to the energy consumed when your electronic device is placed on sleep mode or power-saving mode. It is worth noting that the power consumed in this power mode is a little below the black level but, of course, still higher than when the device is off. When your device is on standby mode, it does necessarily show black or white light. It depends on the application installed in your LED display.


4. Tips to Reduce Your LED Screen Power Consumption


  • Tip # 1: Reduce Brightness

You already know that the amount of power that LEDs consume depends on the intensity they have to continue working. Therefore, one easy way to reduce power consumption for your LED screen is to reduce the brightness of your screen.

The location of your LED wall plays a vital role in this first tip. Of course, you wanted to make sure that your LED screen is bright enough so passersby or whoever is your target audience can notice your display. But you also don’t want to put up an overly optimistic visual show that is already blinding to the viewers. If your LED wall is inside a closed area, for example, a mall where people can see the content from a close distance, you may opt to reduce your screen brightness to a certain level. It’s all about finding the right amount of screen brightness that is attention-grabbing but still eye-friendly.


  • Tip # 2: Use Screen Ambient Light Sensor

Most of the LED screens today have a built-in light sensor. It automatically adjusts the screen brightness of your unit depending on the light intensity of its surroundings.

Light sensors are photosensitive devices responsible for ensuring that your viewers will continue to have a good viewing experience regardless of the fair condition in the area. It makes sure that your screen brightness is never brighter than needed, thus avoiding consuming an unnecessary amount of energy.

You can check the LED screen setting and make sure that this setting is on, so there is no need for you to adjust the screen brightness manually. Please take advantage of this feature by setting it on all the time.


  • Tip # 3: Time Scheduling

There is also a LED screen software application that you can use to help you regulate the power consumption of your LED screen. This time called time-scheduling, allows you to schedule when the display switches off and on.

You can use this software to program the screen brightness of your LED screen. You can set a particular brightness condition to different times of the day. It is helpful in terms of ensuring you have the best image quality throughout the day without constantly checking on it.


  • Tip # 4: Unplug the LED Screen or Use a Power Bar

Like what we have discussed earlier, your LED screen unit still consumes energy even if it is on sleep mode or not displaying any content.

Therefore, if you intend not to use that LED screen for a particular time, it is better to completely turn off the unit to avoid wasting power and energy.

However, many experts say that even when an electronic device like an LED screen is off, it still consumes a small amount of energy. Hence, pressing the power button is not enough.

To avoid wasting even a tiny amount of power, unplug the power cord to the power sockets. You can also use a power bar, so you may switch it on and off when needed.


  • Tip # 5: Switch to Energy-Saving Mode

Another way to reduce the power consumption of your LED screen is by switching on the energy-saving mode of your LED display. It works by dimming the backlight of your LED display screen. This setting can reduce your power consumption by about a third. It is a solution to consider to reduce power during the daytime or when you want to cut down your power consumption.

Although you need to switch off the energy-saving mode when it gets dark outside otherwise, your LED screen display will not be as captivating as it should be. This setting also helps reduce eye fatigue.


5. Other Factors That May Affect The Power Consumption Of Your LED Screen


  • Power Supply Design

The input voltage used in your LED screen affects the power consumption of your LED display wall. Most traditional LED screens are based on a 5V (volts) single-voltage unified power supply. At the same time, the newer and more advanced LED screens adopt a dual-voltage power supply design. In this unique and energy-saving design, the red LED works with 2.8V, and the green and blue LEDs have 3.8V chips.

So, if you want to save more on power consumption, you may ask your LED screen supplier for an LED screen with a dual-voltage power supply design.


  • PCB Board Design

There are also two different PCB board designs used in LED screens. A PCB board design, often referred to as Common Anode, adopts a unified power supply. It utilizes the same amount of power regardless of whether the voltage of LEDs is lower. And there’s the energy-saving PCB board design called Common Cathode.


  • Driving IC

The driving IC is an essential component of any LED display screen. It acts as the nervous system of your LED screen. It is an integrated circuit that controls the brightness and backlighting colors of the LED display.

A typical driving IC like the IC: ICN2037 can save up to 8% energy. While a newer version of driving IC like IC: ICN2049 can help you save up to 25% on your power consumption


  • Brightness Attenuation

The LED brightness will decrease after a certain period of being used. There might also be inconsistencies in diodes’ color production and brightness attenuation.

The red, green, and blue may have different attenuation. As a result, you must not use the electricity they consume.


6. How To Calculate The Power Consumption Of An LED Screen?

You can determine the average power consumption of your LED screen by using the formula 0.1 (voltage x ampere current). Traditional LED screens usually function at 5 volts with 20mA of current. By substituting this value, you will have 0.1 (5volts x 20mA) = power consumption.

But due to continuous development in display technology, many LED display manufacturers are now using LEDs with lower voltage consumption. Replace the formula with the voltage indicated in your LED screen specification. Then, compute the power consumption of your LED screen.
