In engineering applications, full-color LED displays are mainly used to publish information, especially to update information in real time according to changes in the background database.

 A typical application is a train station, which updates ticket information such as train numbers, soft/hard seat tickets, sleeper tickets, and departure time in real time.

As well as the arrival information such as the number of trains arriving at the station, the number of delayed trains, etc., there are also temporary notices, changes of train numbers, advertisements, waiting room location, and so on.

In the integrated information management system of the railway station, compared with the whole system, the information release of the full-color LED display is only part of it.

However, the types, communication types, and distribution locations of full-color LED displays may be very complicated.

 From DLP to LED analysis of indoor large-screen display technology competition

LED display is almost the only choice in the field of outdoor large-screen display technology, and no one can shake its dominance so far.

In comparison, indoor large-screen display technology can be said to be endless: from the original CRT TV wall to a full replacement of DLP rear projection splicing; during this period, LCOS display technology has also appeared in the pan;

In recent years, there has been the rapid rise of flat panel display LCD splicing and the counterattack of plasma splicing;

Nowadays, LED display screens are not reconciled to being in the corner of the indoor advertising and information release market, using small-pitch technology to launch a full-scale attack on the indoor display market.
