Led display industry has enjoyed decades of development from slowly to steadily and rapidly, it seems to be a normal development. However, if we take a careful eye on its development history, we will find the industry development is always in  fast development, although in the past two years it is in a “bottleneck” situation, but it has a rapid relative development compared with industries. Because of the fast development, led display industry market exits some “inevitable” problems.

We can see LED display everywhere is cities and highway, what the bright color brings us are not to enjoy but a negative effect. Such as when night falls, the night sky is lighten by various light source, nobody can catch the natural scenery and when you are driving on road, the super bright display will distract your attention and bread your focus on driving.

This issue has been taken seriously in recent years and has got a significant correction to improve the situation. The relevant administrative departments have taken actions by limit the lighting time and brightness and the led display manufacturers are using the automatic brightness adjustment function to self adjust the brightness according to the environment situation so as to avoid disturb people.

The other problem for led display is ignition. The accidents almost happen every year, perhaps some of the fire is not cause by the led display but the led display security problem is still should be on the agenda. Led display is spliced by a number of led modules, the larger display area, the more modules and greater power consumption and potential treat.
