4. Large electronic systems for indoor football, athletics, hockey stadiums, tennis courts, basketball & volleyball grounds, swimming pools

First of all, you should consider the type of your stadium – open (outdoor) or closed (indoor). If it is indoor, you should choose an inner system (either a rear-projection, or a projection, or a LED screen / sign / display).

If the stadium is outdoor, you should go back to part 2.

The only specific feature is, that several purely informational signs are used in composition for displaying the score, time, etc .Though there are displays that face the stadium during some sports events and are turned to the city (work as ad-screens, for example, in St-Petersburg) but it is determined by the location of the stadium in the city. The use of assembling/disassembling systems is also possible.

The choice of the screen type (for a definite screen size) – the up-to-date lamp, LED, LED cluster, etc. – depends on your financial opportunities.

The largest stadiums in the world have been generally equipped with LED cluster screens / signs / displays (even though they are very expensive). There are also examples of the use of up-to-date lamp systems at large stadiums (40-60 thousand spectators) – in the US & the UK. At first there were CRT screens installed at the stadiums (mostly in Socialist countries). Lamp screens prevail at smaller stadiums (20.000 spectators) in England and America because of their good quality and acceptable price (better than the quality of cheap LED or CRT screens).

The situation in South-Eastern Asia is a bit different:

LED-screens on dot-matrixes are installed at smaller stadiums (anyway they concede to cluster screens, but they are also much cheaper). LED cluster screens are installed at the biggest stadiums.
