Features
The JME-UA200 unit alignment controller is designed to adjust the
luminance of a JumboTron display unit, cell or pixel and to check their
operations.
The main functions of the JME-UA200 are as follows:
Eleven types of test signals
The built-in test signal generator of the controller displays eleven types of
test signals, allowing you to check various circuits and functions of a
JumboTron display unit.
Luminance adjustment of a cell and pixel as well as the whole unit
You can specify a cell or pixel (a single light emitting element of R, G and
B) which composes a JumboTron display unit and adjust its lumincance.
This allows you to obtain luminance uniformity of the whole screen.
Automatic luminance adjustment
After measuring the data of a cell which is emitting light correctly using a
sensor (not supplied), you can adjust other cells automatically to the same
data as the correct cell.
Function check of a JumboTron display unit
You can check whether a JumboTron display unit is operating properly, or
check the current conditions of a unit.
Demonstration
The controller can display a test signal automatically on a small screen,
which is a combination of several units (up to 16 units), for a
demonstration.
