LED displays have limited service lives and will not last long enough without proper maintenance.
So, what determines the service life of LED displays?
It is important to suit the remedy to the case.
Let’s take a look at the factors that determine the lifespan of LED displays.
1. The influence from the performance of components used as the light source.
LED bulbs are essential and life-related components of LED displays.
The life of LED bulbs determines, not equals, the life of LED displays.
Under the condition that the LED display can play video programs normally, the service life is supposed to be about eight times that of LED bulbs.
It will be longer if LED bulbs work with small currents.
Functions LED bulbs should have included: attenuation character, moisture-proof and ultraviolet-light-resistant abilities.
If LED bulbs are applied to displays without proper evaluation of the performance of these functions from LED display manufacturers, a large number of quality accidents will be caused.
It will seriously shorten the service life of LED displays.
2. The Influence from supporting components
In addition to LED bulbs, LED displays have many other supporting components, such as circuit boards, plastic shells, switching power sources, connectors and housings.
The quality problem of any component may reduce the service life of displays.
Therefore, the service life of displays is determined by the service life of the component with the shortest service life.
For example, if the LED, switching power source and metal shell of a display all have a service life of 8 years, and the protective technique of the circuit board can only sustain for 3 years, the display’s service life will be seven years, for the circuit board will be damaged three years later due to corrosion.
3. The influence from the led display manufacturing techniques
The manufacturing techniques of LED displays determines its fatigue resistance.
It is difficult to guarantee the fatigue resistance of modules produced by an inferior three-proofing technique.
As the temperature and humidity change, the surface of the circuit board may crack, resulting in the deterioration of the protective performance.
Therefore, the manufacturing technique is also the key factor that determines the service life of LED displays.
The manufacturing technique involved in the production of displays includes: the storage and pretreatment technique of components, welding technique, three-proofing technique, waterproof and sealing technique, etc.
The effectiveness of the technique is related to the selection and proportioning of materials, parameter control and the ability of workers.
For most LED display manufacturers, the accumulation of experience is very important.
The control of the manufacturing technique from Shenzhen Yonwaytech LED Display factory with decades years of experience will be more effective.
4. The influence from LED screen working environment
Due to the difference among purposes, working conditions of displays vary greatly.
In terms of the environment, the indoor temperature difference is small, without the influence of rain, snow or ultraviolet light; the outdoor temperature difference can reach seventy degrees, with extra influence from wind, rain and sunlight.
The working environment is an important factor affecting the service life of displays, for a harsh environment will aggravate the aging of led displays.
5. The influence from the temperature of components
To fully reach the length of the led display service life, any component must keep a minimum consumption.
As integrated electronic products, LED displays are mainly composed of the control boards of electronic components, switching power sources and bulbs.
The service life of all these components is related to the working temperature.
If the actual working temperature exceeds the specified working temperature, the service life of display components will be greatly shortened and LED Displays will be seriously damaged too.
6. The influence from dust in the working environment
To better prolong the service life of LED displays, the threat from dust should not be overlooked.
If LED displays work in an environment with thick dust, the printed board will absorb much dust.
The deposition of dust will affect the heat dissipation of electronic components, leading to a rapid rise of temperature, which will decrease the thermal stability or cause electric leakage.
The components may burn in serious cases.
In addition, dust can absorb moisture and corrode electronic circuits, causing short circuits.
The volume of dust is small, but its harm to displays should not be underestimated.
Therefore, regular cleaning must be carried out to reduce the possibility of breakdowns.
Remember to disconnect the power source when cleaning the dust inside displays.
Only the well trained staff can operate it well and always remember to make safety firstly.
7. The influence from moisture environment
Many LED displays can work normally in damp environments, but moisture will still affect the service life of displays.
Moisture will permeate IC devices through the junction of encapsulation materials and components, causing the oxidation and corrosion of internal circuits, which will lead to broken circuits.
High temperature in the assembly and welding process will heat the moisture in IC devices.
The latter will expand and generate pressure, separating (delaminating) plastic from inside of chips or lead frames, damaging chips and the bound wires, make the internal part and the surface of components crack.
Components may even swell up and burst, which is also known as “popcorn”.
The assembly will then be scrapped or need to repair.
More importantly, invisible and potential defects will be incorporated into products, harming the reliability of the latter.
Ways to improve the reliability in the damp environment include the use of moisture-proof materials, dehumidifiers, protective coating and covers when in led display production from Yonwaytech LED Display factory, etc.
8. The influence from corrosive gases
Damp and saline-air environments can degrade the system performance, for they can accelerate the corrosion of metal parts and facilitate the generation of primary batteries, especially when different metals contact each other.
Another harmful effect of moisture and saline air is forming films on surfaces of nonmetallic components that can degrade the insulation and the medium character of the latter, thus forming leakage paths.
The absorption of moisture of insulating materials can also increase their volume conductivity and dissipation coefficient.
Ways to improve the reliability in the damp and saline-air environments from Shenzhen Yonwaytech LED Display including the use of air-tight sealing, moisture-proof materials, dehumidifiers, protective coating and covers and avoid using different metals, etc.
9. The influence from vibration
Electronic equipment is often subjected to environmental impact and vibration under using and testing.
When the mechanical stress, caused by the deflection from vibration, exceeds the allowable working stress, components and structural parts will be damaged.
Yonwaytech LED Display makes all orders with well vibration testing before delivery to ensure all product with well stable operation in legitimated vibration from delivery or moving in installation.
In conclusion:
The life of LEDs determines the life of LED displays, but components and working environment also plays an important role in it.
The life of LEDs is usually the time when the luminous intensity is attenuated to 50% of the initial value.
LED, as a semiconductor, is said to have a life of 100,000 hours.
But that is an evaluation under ideal conditions, which cannot be achieved in actual cases.
However, if we can obey the several tips above suggested by Yonwaytech LED Display, we will prolong the life of your LED displays to the greatest extent.
