Structure of the JumboTron screen
The basic element of the JumboTron screen is an RGB trio (dot).
A “cell” consists of the dots arranged at a certain interval (picture element
pitch) and a “unit (JumboTron display unit)” consists of cells.
There are two unit types, the LDU-15 series (with 15-mm pitch) and the
LDU-30 series (with 30-mm pitch). You can configure a large JumboTron
screen by arranging the JumboTron display units vertically and
horizontally to suit various uses or locations. An example structure of each
series is as follows:
