The LED display often failures and solution

With the rapid development of the industry LED, the LED display used more widely, especially a full-color LED screens in outdoor media advertising space, has become the mainstream of the outdoor advertising media. But these appearance beautiful, beautiful picture LED display often also can appear so, or that kind of problem. In fact some problems and not the quality of the product itself, and in our daily in use process, and do not pay attention to maintenance and cause. Installed in high full-color LED display, the installation is not easy, it's harder to repair. So the LED display protection is a major issue. Next we to analysis of the cause of the damage caused by the LED display, and how to protection and solve.

The LED lights to high temperature, make the LED display characteristics metamorphism, if the lamps into the water, also can have a big impact.
The power supply voltage of the sudden rise. Let the power supply voltage rise suddenly could be the reason a lot of, such as power supply quality problem, or the users of the improper use of and so on reason can let the power supply the power supply voltage rise suddenly and cause the damage of the display screen.
Lines of some components or printing lines or other wires short-circuit and form the LED display power supply path of the local short circuit, make this place higher voltage.
A LED display because of its quality reason damage forming short circuit, it's original voltage drop is passed on to other LED display.
In the assembly of the time didn't make anti-static work, the LED display internal has been hurt by static electricity. Although pressure is normal voltage and current value, also is caused extremely easily LED display damage.
Often also can appear so, or that problem. In fact some problems and not the quality of the product itself, and in our daily in use process, and do not pay attention to maintenance and cause. Installed in high full-color LED display, the installation is not easy, it's harder to repair. So the LED display protection is a major issue. Next we to analysis of the cause of the damage caused by the LED display, and how to protection and solve.

Generally cause the LED display damage basically has the following reasons

The LED display in practical work is the upper limit for 20 mA current, but often because of various kinds of use in reasons caused current increases, if do not take protective measures, the increase of current more than a certain amount of time after and amplitude LED display can be damaged.

These reasons can cause the LED display current obvious rise sharply, and soon LED display chip will because overheating and were burned. Cause other LED display more current, other LED display will move quickly was burned down, and even critical power supply. It is very easy to small damage is caused major accident.

White LED display screen because there are many advantages, is more and more into the People's Daily life, it's become very great use now. It is the new device, has its own use characteristics. White LED display screen voltage sensitive type of device belongs to. Each LED display current don't work more than 20 mA, more than too much the LED display will be very easy to be burned. The LED display if is normal use, its life is very long. But people in the actual use of the LED display often easily bad, what is truth? In fact is not considering the use of the LED display characteristics and to it and protect circuit.

The protection measures of the LED display, first should have thought of the use of insurance tube. But insurance pipe is a one-off, and reaction speed too slow, already poor effect is also the actual use of trouble, so insurance tube adapted for use in now the LED display lights in finished products, because the LED display light now mainly in the city the glorious of engineering and bright project. The LED display is photoelectric semiconductor devices, in the assembly process in easy to be wounded by static electricity. This needs in the assembly process of static electricity protective. Of course the LED display in use process, often will still meet other problems, if you in use appeared couldn't solve problems instead, can contact ERALED after-sales service hotline, and after-sale technical staff can help you answer. ERALED has been the service and quality as the company development on both sides of the flag, constantly remind us to put the interests of its clients in the first place.
