Hey, I said, recently, several friends who own milk tea shops have been asking me: "This large LED screen looks really impressive, but will it make the electricity bill go up?" " This is a great question! Today we are going to talk about the power consumption of LED screens, and I guarantee that you will never be troubled by "electricity bill anxiety" again after listening.

​​Let’s first understand: the three key factors of LED screen power consumption​​
Do you know? The power consumption of an LED screen is similar to the battery life of our mobile phones. It depends on three hard indicators:

• ​​screen size​ ​: Just like the air conditioner at home, 2 hp will definitely consume more electricity than 1 hp.
• ​​Brightness level​ ​: The difference in power consumption between an outdoor advertising screen in broad daylight and a screen in a shopping mall at night can be two or three blocks.
• ​​Length of use​ ​: If it is turned on 12 hours a day and 3 hours a week, will the electricity bill be the same?

To give a real example, last month a gym owner installed a 20-square-meter indoor LED screen. Guess what? By broadcasting fitness classes around the clock, the electricity bill at the end of the month was less than 300 yuan - which was not as much as he made from selling protein powder in a day!

​​What is the difference in power consumption between different types of LED screens? ​ ​
It’s important to focus here! The power consumption of several common LED screens on the market is similar to that of cars with different displacements:

1. ​​Outdoor advertising large screen​ ​: Just like an SUV in a car, it consumes between 800-1500 watts per hour.

   • During the day, the brightness must be turned on to more than 4,000 nits to see clearly.
   • But many new models are equipped with intelligent photosensitivity, which can automatically reduce the brightness on cloudy days to save power.

2. ​​Transparent window screen​ ​: Just like hybrid models, 300-600 watts per hour

   • A model with a transparency rate of 86% saves about 40% of power than traditional screens
   • A shopping mall in South Korea used this kind of screen for window display, saving more than 2,000 yuan in monthly electricity bills.

3. ​​Floor tile interactive screen​ ​: Similar to a sports car, although the instantaneous power is high, the use time is short

   • When it is turned on for 3 hours during the opening event, the electricity consumption is equivalent to that of an average household for one day.
   • It can attract attention at critical times, and it doesn’t waste electricity when it is turned off at ordinary times.

​​Four power-saving tips to help you keep your electricity bill in check​​

1. ​​Don’t hold back on brightness​ ​: Adjusting the indoor screen to 800 nits is sufficient, but having to increase it to 1,200 nits is a waste.
2. ​​Timer switch​ ​: Install an intelligent controller to save more than 15% of energy compared to manual operation.
3. ​​Choose the right display mode​ ​: Static images save 30% more power than video playback, and text scrolling saves 50% more power than full-screen animation.
4. ​​Have regular physical examinations​ ​: Dust accumulation will reduce heat dissipation efficiency, resulting in 20% more power consumption.

Last year, a celebrity restaurant owner in Shenzhen suffered a loss. The screen was not cleaned after a year of use. As a result, the electricity bill increased by 40% for no reason. Later, I asked the master to take it apart and see that the dust accumulated on the heat sink could be used to grow succulents!

​​The truth those manufacturers won’t tell you​​
There is a black technology in the industry called "low brightness and high gray". It sounds mysterious but it is actually very simple - it allows the screen to maintain a delicate picture even at low brightness. How awesome is this technology? Let’s put it this way:

• Under the same display effect, power consumption can be reduced by 30%-50%.
• Using this technology on indoor screens can save enough electricity to cook two hot pot meals every day.
• Many new models already come with this feature as standard, so be sure to ask when buying.

​​personal opinion time​​
Let me tell you, the power consumption of LED screens is like driving a fuel car - you can't just look at the size of the fuel tank, but also how you drive it. The energy-saving technology of new models is really powerful. Last year, the overall power consumption of the industry dropped by 18%, and it is expected to drop by another 25% in the next three years. Therefore, instead of worrying about power consumption, it is better to choose the right product and use the right method.

Besides, what matters in business is the input-output ratio. Spending hundreds of yuan more on electricity a month, in exchange for customers stopping to take photos and post them on WeChat, is worth it no matter how you calculate it. Do you think this is true?
