What is a LED screen?

The name LED is an abbreviation for Light Emitting Diode. LED screens, or large screens, are made of so-called electro luminescent diodes. In the LED screen the model of colour space is RGB ("R" - red, "G" - green, "B" - blue). The combination of three colours - red, green and blue allows you to create millions of colours, including white. It is the most important parameter of the screen, called a pixel or pitch. Thanks to this LED screens have saturated colours, necessary for contact with the recipient.

So how to choose the right LED screen and adjust the parameters to suit our needs? What you should pay extra attention to?


Key Parameters

  • resolution - the most important parameter of LED screens. Called also pitch, means the density of LED spacing, which affects the quality of the materials presented on the media. To display graphics, numbers, data and other information the maximum screen resolution is required, thanks to which the recipient will be able to read easily the presented content. The readability of the content presented on the screen depends mostly on the distance of the recipient from the screen. The greater the distance from the screen, the lesser concentration of diodes is used. If the LED screen is closer, the density of LEDs is greater. Screen selection depends mostly on the destination of the media. The screens are made of modules. For example, the P10 module (P stands for pixel-pitch) has dimensions of 32cm x 16cm, which is equivalent to resolution of 32 x16 pixels. Therefore, building a screen of 3.2 m x 1.6 m size, you get a screen resolution of 320 x 160 pixels, which results from a simple mathematical operation: 3200mm width (3.2 m) divided by the pitch size (distance between pixels 10mm) which will determine the resolution. In such case, it is a horizontal orientation. Similarly, we define a vertical orientation. 1600mm are divided by the pitch size. To obtain a high quality of a picture (resolution), LEDs should be placed as close as possible to each other - that is, very densely.
  • LED type - there are several types of diodes. First of all, there are DIP LEDs used in the outdoor screens, and new solutions - SMD LEDs. They can be used in indoor and outdoor media.

The screen brightness depends on whether the screen is set indoors or outdoors:

  • standard brightness for outdoor screens oscillates around 5000 - 7000cd/m²,
  • outdoor screens with higher brightness: 8000 - 12000cd/m²,
  • indoor screens brightness ranges from  700cd/m² to 2500cd/m².
Maintaining the stated minimum values ​​allows clear picture reception, even at very high insolation.

Number of colours and refresh rate:

  • All our screens from Sceo®LedScreen series have a very high refresh rate, above 1000 Hz and colour processing at 16 bits per colour.

Purpose of the screen

  • Mobile LED screens
In addition to the parameters on which you should pay a lot of attention, it is important to clarify the purpose of the screen. If you need a LED screen, which will display content in several different places, you can use the so-called mobile screens. Because they are installed on car trailers, their height can be adjusted, and you can change their location depending on the needs. Moreover, these screens do not need to be dismantled every time you need to move them. Mobile screens work well in all weather conditions and are the perfect addition to outdoor events.

  • Rental LED screens
For frequent change of media location portable (rental) screens are perfect. They are built of lighter materials, and fitting them with special latches and quick connectors allows a rapid assembly and disassembly of the structure. For transporting rental screen modules the so called cases are used - special boxes for storage and transport. Rental screens are also perfectly suited for arrangement  of sport bands.
  • LED Curtain
LED curtains are the best for irregular spaces, as well as for making of original and spectacular scenery. Installed inside of buildings or in open spaces they may be hung on any building structure, because of their low weight. LED curtains can be of any shape, and their use depends only on the needs and requirements of customers. Soft and rigid curtains, or their different dimensions, are just a few examples of possibilities offered by the LED curtains.

  • LED floor/ Interactive floor
To intensify the effect of communication you can use a different form of media. Fantastic visual experience will be provided by LED floor, which can be an independent or additional element of the stage design. It can be synchronized with multimedia framework and used during various types of events, such as exhibitions or shows. Above all, it works in television entertainment programs, highlighting the uniqueness of each event. The key thing is to choose the type and parameters of the screen to suit your needs. Attention should be paid to what place the screen will be located in, how many people should see the displayed content, what kind of materials will be displayed on the screen (the numbers, pictures, presentations), as well as how far from the recipient shall the screen be located. If you properly specify these indicators, the bought large screen will certainly fulfil its purpose.
