ADVANCED ALIS PANEL – UP TO 1,200cd/m
2
The ALIS (Alternate Lighting of Surfaces) technology will
dazzle you with its ability to match high definition input
signals. With a fine pitch display of approximately 1.05
million pixels (1,024 x 1,024), every detail is reproduced
t
o perfection.
I
n all models precise, vertical 1,024 pixels and a high
luminance effect are made possible by emitting light from
even numbered and odd numbered lines alternatively
every 1/50 second.
O
ur 42” model comes with a panel luminance whitepeak of
1,200cd/m

, enabling unprecedented clear, bright pictures.
All models bring you stunning high contrast images.
Allowing you to experience magnificent viewing from high
quality sources such as high definition digital broadcasts.
TRUE HIGH DEFINITION IMAGES
The ALIS panel is developed to match high definition input
signals. 1,080 lines are displayed with minimal interpolation
processing, thereby displaying true high resolution images.
LONGER PANEL LIFE
By lighting the screen lines alternatively, the ALIS
technology panel significantly reduces the wear on screen
phosphors, thus the 7800 series achieves an average
panel life of approximately 60,000 hours (when panel life
function is used).*
* 60,000 hours to half original brightness based
on measurements in Hitachi's standards.
