What is a LED Screen?

A LED screen is a video display which uses light-emitting diodes. An LED panel is a small display, or a component of a larger display or screen. They are typically used outdoors in store signs and billboards, and in recent years have also become commonly used in destination signs on public transport vehicles. LED panels are sometimes used as form of lighting, for the purpose of general illumination, task lighting, or even stage lighting rather than display.

What is the refresh rate for LED screens?

The refresh rate of a LED screen is the number of times in a second that the LED screen hardware draws the data. This is distinct from the measure of frame rate in that the refresh rate for LED screens includes the repeated drawing of identical frames, while frame rate measures how often a video source can feed an entire frame of new data to a display.
For example, most movie projectors advance from one frame to the next one 24 times each second. But each frame is illuminated two or three times before the next frame is projected using a shutter in front of its lamp. As a result, the movie projector runs at 24 frames per second, but has a 48 or 72 Hz refresh rate.

What is the life time for our LED screens?
The life time for our LED screens is over 100,000 hours, but it depends how the client is taking care of his LED screen and how it is used. When a LED Screens´ life time will get to 100,000 hours, it means that the brightness of the LED´s of the LED screen is about 50% of it´s original brightness, depending on several factors that will enlarge a LED screen´s life time or reach 100,000 hours.

LED Screen Maintenance
Maintenance is a very important factor, dusty environments require more often maintenance to the LED screen than clean environments. The soldering of the LED chips can dry out and break which require changing often pieces like LED modules and receiving cards.

LED Screen Temperature
The temperature of the LED screen is very important to keep it cool. In hot environments it is wise to install a cooling system inside the LED screen to avoid overheating.

LED Screen Power Protection
Electrical peaks can put more force on the electrical components which will decrease life time. It is wise to install a protection that can control the peaks.

LED Chip Packaging
The LED chip packaging material is also a very important variable that will determine the lifetime of a LED screen. For example iron has less life than cuprum LED packages. Besides iron is more corrosive than cuprum.
