Running line in Kazakhstan.
Running line — the electronic device intended for display of text and graphic information. In the simplest option the text just "runs", moving from right to left. The displaying matrix usually consists of light-emitting diodes. Very often besides a plain text, running lines can generate the elementary graphics and impose various effects on the displayed text.
The running line can be one-color and multi-color.
The text displayed in the line loses sooner or later the relevance therefore it needs to be updated periodically.
Process of updating consists in connection of a running line with the personal computer of the user and loading of new information. Connection can be established by means of various interfaces. The most popular it is RS-232 (COM port), Ethernet, USB, a radio channel, a GSM network, bluetooth and so on.
LED boards "running line" can be used not only in rooms, but also on the street. The aggressive atmosphere and severe climate force producers to use dust and water tight cases, to glue printed circuit boards special plastic, to warm a design and to provide ventilation. Options in northern execution have automatic heating.
But besides severe conditions one more factor — sunshine which light symbols takes place and reduce picture contrast. To resist to influence of a flare, manufacturing firms use brighter light-emitting diodes: if for rooms brightness of each light-emitting diode to 1-2kd, then for street option this indicator is much more.
