The
coolest and most efficient engine
Just like Barco’s 16:9 LED video walls, the new
OVL series has an advanced heat management system based
on liquid cooling technology, which brings the LED temperature
down to the optimal level. This results in a significantly
longer lifetime of the projection system, amounting to
80,000 hours of continuous operation in eco-mode –
or a 35% improvement over competing video walls.
Thanks to liquid
cooling, it is possible to boost the OVL’s brightness
level up to 20% without shortening the system’s
lifetime. This effectively makes the OVL the brightest
LED-lit video wall on the market. Conversely, it is possible
to prolong the system’s lifetime by lowering the
brightness level. This way, Barco proves that liquid cooling
is very effective in counteracting LED aging effects.
OVL video walls can save up to 30% power compared to other
LED-based systems. Barco achieves this by basing the OVL’s
color and brightness adjustment on smart power management,
not on optical dimming.
Thanks to the
OVL’s new LED engine, offering higher brightness
and higher efficiency, the use of larger screens has become
possible. Barco's OVL range therefore includes an 80”
video wall system with seamless screens, which is particularly
interesting for utilities applications. An additional
benefit over smaller size screens is the 80” OVL’s
high mean time between failures.
The
warmest colors
Barco's OVL rear projectors come with Sense6, a unique
sensor technology which co-ordinates across multiple rear-projection
modules to provide brightness and color stability over
time and across the entire video wall screen. Unlike factory
calibrated systems, the OVL continuously measures and
adjusts color and brightness in real time and therefore
requires no maintenance or manual adjustments.
Barco's LED expertise
The OVL video wall completes Barco's range of LED-based
video wall systems, which also includes the 16:9 OL video
walls launched in 2009. Barco's LED-lit video walls tackle
a large number of challenges faced by most other video
wall systems used today. By combining the advantages of
using LEDs instead of lamps to create the images, with
a number of cutting-edge technical innovations, Barco's
LED video wall series offer saturated colors, low maintenance
and usability in critical 24/7 applications.
