Vertical box:

Box-type vertical LED color screen equipment does not rely on other buildings, and is independently set up in public places, generally built at busy commercial street intersections, in front of large shopping malls, bus stops and other places. Due to the limitations of the placement environment, the area of such advertising screens is not large, basically within 5 square meters.

Focus Media, which started with LCD advertising, also entered the field of outdoor LED advertising in 2006. About 200 outdoor LED color screen devices have been set up in Shanghai, and outdoor LED color screen simulcast networks will be built in Beijing, Guangzhou and other places.

Focus Media believes that compared with the traditional outdoor advertising form, the dynamic continuous playback of LED display screen is not only easy to attract people's attention, but also has large information capacity, long service life and stable playback.
