(1) Economic Lifespan

The economic life of the LED display is used to determine the best discount period and the best update time for the display.

Its specific meaning refers to the service life of the LED display based on the lowest average annual use cost.

(2) Technical Lifespan

Technical life refers to the period during which a product has technical value.

That is the stage from when LED screens are put into use on the market to when they are replaced by new display devices using new technologies.

At present, LED video walls are widely used in various indoor and outdoor scenes, covering many fields such as advertising, entertainment, sports, and film and television production.

(3) Service Lifespan

The service life of the LED display refers to the time from the time the LED display is put into use to equipment damage and failure.

The main topic we discuss in this blog is its service life.

(4) Average Lifespan

The theoretical life of LED is 100,000 hours. However, considering the impact of the use environment, the average lifespan of LED video walls is generally 6-8 years.

2. Factors Affect LED Screen Lifespan

Understanding the factors that affect LED screen lifespan helps you focus on the performance of the product when purchasing.

Next we will explore what factors will affect the service life of LED panels.

(1) Temperature

LED screen cabinet is composed of many parts: light-emitting devices, switching power supplies, control boards of various electronic components, etc.

The life of these electronic components directly affects the LED screen lifespan. And their normal operation is closely related to temperature.

If the working environment of the display screen or the heat dissipation design of the display screen is unreasonable, and the working temperature exceeds the applicable range specified by the product.

The service life of the screen will be greatly shortened.

This is why LED displays must be equipped with an excellent heat dissipation system. For example, outdoor LED screens use fans to dissipate heat.

(2) Dust

First, the deposition of dust will affect the heat dissipation of electronic components. We mentioned above that excessive heat can cause damage to the electronic components inside the display.

Secondly, dust will also absorb water vapor in the air, corroding electronic circuits and causing short-circuit failures.

Therefore, dust on the display surface should be cleaned regularly to reduce the probability of failure.

When you clean the dust inside the box, remember to disconnect the power and operate with caution.

If you are not a professional maintenance person, it is recommended not to disassemble the LED box easily.

(3) Humidity

Humidity is an important factor affecting the life of LED displays.

The main manifestation is that moisture will enter various precision components through packaging materials and cause internal circuit short circuits. Such as lamp beads, IC, PCB, etc.

So what moisture-proof and waterproof measures have been taken by LED display manufacturers to improve the protective capabilities of LED displays? Below we list some:

  • The module surface is filled with glue to protect the lamp beads (such as the GOB LED display, and outdoor LED module)
  • Use a sealed box with good waterproof properties
  • Use moisture-proof materials
  • Protective coating cover
  • Use waterproof rubber rings to prevent rainwater from entering the inside of the cabinet

(4) Corrosive Gases

Areas near the sea need to consider the impact of the salty air environment on the display. Because they can intensify the corrosion effects of metal parts.

The absorption of moisture by insulating materials can also cause an increase in the material’s volume conductivity and dissipation coefficient.

Corresponding protective measures include using corrosion-resistant box materials and using special coating seals.

(5) Vibration

Electronic equipment will inevitably receive some impact or scratches during transportation or use.

For example, if the LED screen is hit during transportation, it may cause lamp knocking or physical damage to other components.

Therefore, good anti-collision design and earthquake resistance level can ensure the integrity of the LED screen and greatly extend its working life.

(6) Load

Integrated chips, LED lamp beads, and switching power supplies all need to work under rated loads.

Taking power supplies as an example, branded power supplies can output 105% to 135% of power.

However, if the power supply is operated under such a high load for a long time, the aging of the switching power supply will inevitably be accelerated.

The aging of electronic components will inevitably affect the service life of the entire product.

Therefore, large-scale LED display projects require specialized power distribution cabinets.

Its function is to distribute electric energy to various load parts and provide power-off protection in case of circuit short circuit, overload and leakage.

3. How to Improve LED Display Lifespan?

Products with a long service life are more likely to be favored by customers. This means you get longer-term economic benefits while reducing replacement costs.

So how can we ensure that the LED display screen has a long service life?

(1) Use High-quality Raw Materials

LED display products with superior performance are inseparable from the blessing of high-quality raw materials.

The quality of raw materials is an important factor affecting the service life of LED walls.

The quality of lamp beads, IC, power supply, and other accessories not only affects the image effect of the screen but also affects the service life.

Therefore, if your budget is sufficient, it is recommended that you specify high-quality raw material brands in the industry for long-term considerations.

For example, Chipone, Macrobloc driver IC, NationStar, Kinglight lamp beads, etc.

(2) Standardized Production

Well-equipped modern and standardized SMT production workshops and assembly workshops ensure the production of high-quality products.

During the production process, pay attention to anti-static measures. Workers can wear static rings, anti-static work clothes, etc.

In addition, dust-free workshops and clean production lines and assembly lines minimize product failure rates.

(3) Strict Aging Test

LED display modules and LED screens can only be delivered to customers after passing a strict aging test process. Aging testing is an important step in finding problems before leaving the factory.

The test contents include a white balance test, video test, etc.

The aging of LED display screens is divided into white light aging (4 hours) and video aging (48 hours).

(4) Correct Daily Maintenance

In addition, daily maintenance of LED display screens is also very important. for example:

Clean accumulated dust from the screen regularly.

Do not play all-white, all-green, etc. images for a long time to prevent faults caused by excessive current.

When playing content at night, adjust the screen brightness according to the environment.

In short, measures to extend LED screen lifespan are implemented in multiple stages of production, aging, and daily maintenance.

4. How to Make the LED Display Maintenance in Winter?

Electronic LED screens have high-temperature protection requirements and require cooling measures. At the same time, LED electronic screens also need maintenance in the cold winter.

Below we will focus on communicating about the impact of various environments on LED electronic screens and countermeasures.

(1) Power Supply

In high-latitude countries such as Russia or Canada, winter temperatures can drop as low as -30 degrees.

Low-temperature environments have special requirements for many materials of LED electronic screens.

For example, ordinary power supply cannot start normally when it is below -20 degrees. The reason is that the medium inside the electrolytic capacitor inside the ordinary power supply is liquid.

When the temperature is lower than a certain value, the liquid will turn into a solid, so it cannot start normally.

Therefore, when choosing an LED electronic display, we should understand the installation location and installation environment of the LED electronic display.

If the LED electronic display fails to start because the temperature is too low, specific equipment is required.

For example, use air conditioning or heating equipment to increase the temperature, and the power supply capacitor can be started normally after thawing.

(2) Material of LED Screen Cabinet

In addition, LED electronic screens are composed of many plastic parts, such as LED module kits, shells, and masks.

We probably all know that plastic parts are made from new raw materials.

Another method is to recycle waste materials for secondary use after treatment, and some even process waste plastic raw materials multiple times.

If the plastic parts of the LED electronic screen are made of inferior waste materials, their structural strength is insufficient, causing the surface of the LED electronic screen to be uneven.

Low temperatures will cause the LED electronic screen module to freeze and crack, so it is recommended to choose better plastic raw materials.

(3) Anti-static

Static electricity is a major killer of LED displays. Not only will the service life of the display be reduced, but the discharge may even break down the electronic components inside the display and damage the display.

Whether it is an indoor LED display or an outdoor LED display, static electricity is easily generated during use, which brings safety risks to the display.

By adding a ground wire to the monitor, the static electricity generated by the monitor can be conducted to the earth promptly.

In addition, staff must wear an electrostatic bracelet when operating the display to prevent screen damage caused by static electricity carried by the human body.

(4) Condensation

Condensation is also a huge threat to LED displays and is extremely harmful to outdoor displays.

Although the outdoor display will be waterproof, due to the condensation of water vapor in the air, small water droplets will adhere to the surface of the PCB board and module of the display.

If waterproofing is not done, the PCB board and module will be corroded, resulting in reduced lifespan or even damage to the LED display.

The solution is to choose one with a waterproof coating when purchasing a display. It enhances protection for use in harsh outdoor environments.

(5) Ensure Appropriate Temperature

Low-temperature environments will also affect the operation of LED displays. The operating temperature range of most outdoor LED displays is -20°C to 60°C.

Too low a temperature can cause some semiconductor components to become less active or even unable to work. Some plastic parts may freeze due to low temperatures.

Try to pay attention to its working temperature and do not light up the LED display when the temperature is too low.

It is also recommended to check the display screen regularly for damage.
