What is a LED Screen
A LED screen is a display which uses light-emitting diodes. An LED panel is a small display, or a component of a larger display or screen. Originally used outdoors as store signs or billboards, LED’s are now used as indoor screens and 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 in a display.
Types of LED Screens
There are two types of LED panels: conventional (using discrete LEDs) and surface-mounted device (SMD) panels. Most outdoor screens and some indoor screens are built around discrete LEDs, also known as individually mounted LEDs. A cluster of red, green, and blue diodes is driven together to form a full-colour pixel, usually square in shape. These pixels are spaced evenly apart and are measured from centre to centre to give the measurement known as pixel pitch.
Most indoor screens on the market are built using SMD technology, a trend that is now extending to the outdoor market. An SMD pixel consists of red, green, and blue diodes mounted on a chipset, which is then mounted on the driver PC board. The individual diodes are smaller than a pinhead and are set very close together. The main drawback in SMD screens for outdoor use is that the maximum viewing distance is reduced by 25% from the discrete diode screen with the same resolution.
Pixel Pitch and Minimum Viewing Distance
The term Pixel Pitch is one that you will see listed with every LED Screen. It is the measurement from the centre of one LED to the centre of the next LED. Therefore a P6 screen has a 6mm gap between each pixel (SMD) or each LED of the same colour (discrete).
Common LED sizes are P2, P4, P6, P7.2 and P10 for indoor applications and P7.2, P10, P12, P16, P20 and P25 for outdoor applications.
The easiest way to calculate the minimum viewing distance to watch a LED screen is 1meter of distance per 1mm of pixel pitch. An outdoor P10 screen would have a minimum viewing distance of approximately 10 meters.
What is the lifespan for a LED screen
The lifespan for a good quality screens is over 100,000 hours, but it depends how the client is taking care of his LED screen and how it is used. The most important factors in getting the most out of your LED screen are;
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 the LED modules and the 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 Quality
The most important factor is to have a LED screen that is build correctly. LED Screens Australia uses only components of the highest quality.
What size screen do I need
This is a very hard question to answer because each client’s requirements will be different. How far away will the viewers be? What type of information will be on the screen? Is the screen indoor or outdoor? Is the screen or scoreboard in direct sunlight? These are the questions that need to be taken into consideration before the correct screen can be chosen. Please call LED Screens Australia with help in choosing the correct LED screen or Scoreboard for your needs.
What can I show on my LED Screen
The answer is pretty much anything. From Jpegs and still images to a Full HD video. From a single line of text to a cricket scoreboard. TV, Foxtel, PC display, Custom Graphics. As long as you have the correct size and resolution on your screen, anything is possible.
How much does a LED screen or LED display cost?
The price or cost of a LED screen, LED display or electronic billboard depends on two variables. Those two variables are the total size of the LED screen, and the total resolution of the LED screen.
The total size of the LED screen: The bigger or larger the LED screen the higher the cost. The prices are based on USD/sqm, which means that if the total size is 24sqm, the price will be 24 multiplied by the cost per sqm.
The total resolution of the screen: The more pixels, or the more number of LED´s, the screen has the higher the cost will be. For example if a screen is 12sqm and has 49,000 pixels, it will be cheaper if the LED screen is 12sqm with 120,000 pixels. This is because more LED lamps will be placed onto the screen which is a higher cost. But on the other hand the more LED´s the screen has, the higher the detail will be of the videos and images that the LED screen will be publishing.
Why LED screens have different costs and prices?
Everything depends on the customers´ needs. Some customers want the public to see their LED screen from a distance of 10 meters and further, and others from 20 meters and further. The more resolution/sqm a screen has the closer will be the viewing distance without loosing detail looking at the screen from closeby. For that we always need the client to answer us several questions to determine the right LED screen size and resolution and come with the right proposal. Nothing is predetermined, but based on the needs of the client.
If you want to know what are our prices per square meter please let us know and give us a call, or contact us by writing an email or online chat. We can send you our prices and you can figure out what will be the right size and right resolution for your LED screen that fits your budget.
