Adjusting The Luminance Manually - Sony Jumbotron JME-UA200 Service Manual

Adjusting the Luminance Manually

This section explains how to adjust the luminance manually in accordance
with the menu in the display window. You can adjust the luminance each
of the unit, cell and pixel
the whole screeen.
There are eleven manual modes for each type of the JumboTron display unit.
JTU-35

* The luminance levels of blue, red and green are changed simultaneously in any
of G1-VOLTAGE modes. You cannot adjust three colors separately.

* Do not change the REF-VOLTAGE settings. If you have changed, then set the
REF-VOLTAGE levels to 00.

1) Pixel
The smallest element of the light emitting body of the
JumboTron screen. Each of R, G and B elements which
makes up a trio is called a pixel.

2) PWM
Abbreviation for Pulse Width Modulation.
The JumboTron display unit changes the light emitting time of
each color by adjusting the pulse width of the basic clock in order
to change the luminance level.
