Mitsubishi Electric
has previewed production prototypes of its latest LED display
at the CEATEC technology show in Japan. Named Resolia, the
new system is the first Mitsubishi LED display designed specifically
for indoor digital signage applications. Despite a display
size measuring an impressive 1.8m tall by 3.1m wide (140"
screen diagonal), the Resolia is just 150mm deep, making it
the slimmest LED screen ever produced by Mitsubishi. The ultra-thin
profile of Resolia enables its use in places until now considered
impractical for LED systems.
The use of digital signage is growing rapidly around the world.
Due to its high light output, LED is an extremely effective
display technology in applications such as railway stations,
airports, shopping malls and atriums where high ambient light
levels are common. However its relatively large form factor,
weight and space requirement for cooling and maintenance has
so far limited its appeal in many situations where it would
otherwise provide the ideal solution. Applications such as
shop windows or display cases, for example. Along with the
physical problems of module size and weight, indoor LED screens
are usually assembled in-situ from smaller individual LED
modules, the fitting and aligning of which is a labour-intensive
and time-consuming task.
Despite being based on Mitsubishi's
tried-and-tested LED technology, Resolia has been designed
from the ground up as a pure-bred digital signage solution
that is practical, easy and quick to install in virtually
any location. Through careful redesign on the internal layout
and improved cooling systems, the depth of the Resolia display
has been reduced to 150mm - half the depth of Mitsubishi's
existing IDT series screens. Resolia is also completely front
access, meaning it can be installed flush against an area
boundary or wall, greatly reducing the space required. Finally,
its integrated screen design means that installation is simply
a matter of connecting signal and power cables. No further
LED module alignment is needed.
The display specifications of Resolia are identical to Mitsubishi's
highly successful IDT4 Diamond Vision system: True 4.00mm
pixel pitch, 3-in-1 LEDs deliver 1500cd/m² light output
and startlingly clear image quality. Resolia employs the same
"Black Package" LEDs as used in the IDT4 screens
to deliver exceptional contrast performance and perfect noise-free
blacks. Clever design ensures viewing angles of 120º
vertical and 150º horizontal, with no colour distortion
even when viewed off-axis. A pixel density of 62,500 pixels/m²
reduces minimum viewing distance is just 1m, making Resolia
ideal for close-viewed applications such as shop displays.
Its exceptionally slim, front access design and relatively
low weight makes Resolia a very practical solution for most
retail and public environments.
Resolia enters full production on November 1st and will be
launched officially in Europe at ISE 2008 in January. Pre-production
preview models will be on show at SATIS in Paris (October
23-25), Broadcast in Madrid (November 6-9), at ISE Russia
(November 8-9) and SoccerEx 07 at the Sandton Centre in South
Africa (November 25-28).
