LCD Module Optical Performances
The typical screen luminance and contrast ratio for the LM130A-12C318 sunlight readable LCDmodule are shown in
the figures below:
The
measured with the LCD in the
“
Off
”
state (i.e. the pixels are not energized).
This is the
“
White
”
state that provides
the maximum luminance. Very often,
this
“
Off
”
state is slightyly brighter
thanthe
“
White
”
colordisplayedonthe
screenwhentheLCDisturnedon.This
result may be caused by the LCD
controller card or the video signal
driving the display. When the LCD is
properly
driven,
between the luminance of the
“
Off
”
state and the
“
White
”
color should be
less than 10%.

measured in a dark room. In outdoor
environments, the contrast ratio of the
display drops significantly due to the
reflections and glare caused by the
ambient illumination at the front
surface of the LCD and other layers,
such as a touch screen or a protective
window.
