Screen Advantages Over Other Information Media

Controllers and display software
allow running the screen without an operator involvement basing on the pre-set parameters; the screen operation can be distantly carried out. Comparing to the other competitive technologies, LED and SMD screens provide higher contrast range when the ambient illumination is great. In this case more noticeable pixelization is compensated by more intense brightness and a wider color range. As a result we have a possibility to get much more intense and clear colors. In this case, a frontal projection even with a usage of projectors of the latest generation requires a very complicated operation of the outer light. A rear projection (when the screen is working at the opening) undoubtedly is much more effective than a line in the view of provided contrast. But at the same time it needs a great empty area behind the screen and in color strength it can not compete with LED screens. Video walls also require a lot of space (as a rule, starting from 60 cm in depths) and not everyone likes obvious joints on a display. Besides, video cubes, which video walls are made of, keep their characteristics at an acceptable level only in relatively stable working conditions, for example, in dispatcher’s halls where they are never turned off. Video walls can also face some problems with lamps used in projecting modules as a source of power. The problems are caused not so much by lamps’ reliability as by the difference between their spectral characteristics in different deliveries what leads to a deregulation of a color rendering on separate cubes and therefore to a necessity of their adjusting from time to time by a qualified engineer. As for LED screens, they do not have such problems, stability of their parameters is higher, so their operating costs are lower.

The viewing angle of LED screens is relatively wide both horizontally and vertically (visible horizontal angle is almost 160º)

Main advantages of LED screens that caused their wider expansion are exclusively high brightness and the possibility to use them in any weather conditions including outdoors under bright sun.


Brightness of indoor SMD screens is 1200 -3000 cd/m². For comparison: normative brightness of a cinema display is 20-60 cd/m², working brightness of a computer display is 200 cd/m², brightness of video walls or plasma panels is 300-500 cd/m². It means that indoor SMD screens are inferior only to outdoor LED screens with the brightness of 3500 – 7000 cd/m². One of the main advantages of LED displays is a wide adjustment range of brightness (from 100% to 0%) which can be hardly reached by other image generation technologies.

LED technology is superior to all other technologies also in terms of a service period – light-emitting diodes manufactures claim that LED screens can work up to 100 000 hours (maximum) and up to 50 000 hours without changing their optic and bright characteristics.


Advantages of LED displays are not only determined by their brightness and optic characteristics but also by their construction based on a modular principle.

Cabinet size equals 50x50 cm, sometimes it is even bigger. Modules depth is within 16 cm (up to 35 cm together with headers and cables). The rigidity of a cabinet frame construction is so high that it allows assembling sufficiently large screens (3 – 4 m high) without any additional bearing structure. You can hang up to 10 cabinets (it allows to assemble a screen with 6-8 meters high).

Construction distinctive features and main advantages of all screens is their modular structure that allows creating a mosaic, a hemisphere, building them into stages and dance halls, etc. Everything just depends on your imagination.
