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, however in recent years are now used for indoor advertising.
What is a LED?
Light-Emitting Diodes are an energy efficient, long lasting, more physically robust alternative to traditional incandescent light bulbs. It is a semiconductor light source that does not contain filaments like light bulbs. So it will not “burn” out. They are often created in small sizes and are capable of fast switching times which make them perfect for use in electronic signage.
What does RGB mean?
The term for the colour composition of displays. Red, Green, and Blue light are used in variation to create the colour spectrum.
What is a Pixel?
A pixel is a point of light. An LED display is made up of an array of pixels, multiple points of light appearing as dots. A pixel can be as small as one LED or it may contain a cluster of LEDs that act as a unit. Our displays contain pixel clusters of 3 LEDs (1R 1G B).
What is a Pixel Pitch and the Minimum Viewing Distance?
A pixel pitch is the distance from the centre of an LED cluster (or pixel) to the centre of the next LED cluster/pixel measured in millimetres. Pixel pitch typically ranges from 1.9mm up to 20mm for indoor LED displays; for outdoor displays, pixel pitch canrange from 2mm to 16mm or higher. Pixel pitch directly correlates your display resolution and optimal viewing distance. The smaller the pixel pitch number, the more pixels used to make up the image on your display, thus improving the resolution and optimal viewing distance. The easiest way to calculate the minimum viewing distance to watch a LED screen is 1 meter of distance per 1mm of pixel pitch.
SMD or DIP?
Most DIP screens have a separate LED (R, G, B) for each of the three main colours: Red, Green, and Blue. Some have an extra red LED, forming one square pixel from 4 lights. SMD LED screens are usually use 3-in-1’s, which are smaller, thinner, and brighter. There are DIP 3-in-1 bulbs, but they cost more and are naturally bigger than their SMD equivalents. SMD LED light source is a very small with light chips enveloped in epoxy resin Generally speaking, the voltage per SMD LED is 2-3.6V, current 0.02A-0.03A, with very low voltage, current, and power consumption. The life span of SMD LED is longer due to Automatic Equipment’s heat emitting process. SMD a lot brighter, the colours are more vivid and true, and the picture is crisp and sharp. DIP displays are still cheaper to make, and because SMD is a newer technology, DIP on average has a longer lifespan or shelf life.
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.
What Maintenance is required for a LED Screen?
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.
What can I play 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 scoreboard. TV, Foxtel, PC display, Custom Graphics. As long as you have the correct size and resolution on your screen, anything is possible. The LED Screen can be operated using a Computer and or a video processor.
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.
