Structure of the JumboTron screen
Two types of the JumboTron screen are available. One is the conventional
CRT type screen in which light emitting bodies of three primary colors (R,
G and B), “Trinilite,” are used as the light emitting element. The other is
the new LED type screen in which light emitting diodes of the three
primary colors are used.
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 12 cells for the
CRT type and 16 cells for the LED type.
There are three unit types, the JTU-35 series (with 35-mm picture element
pitch) and JTU-17 series (with 17.5-mm pitch) of the CRT type, and the
LDU-15 series (with 15-mm pitch) of the LED type. You can configure a
large JumboTron screen by arranging the JumboTron display units
vertically and horizontally to suit various uses or locations.
