Barco announced a new line of LED-lit, DLP-based videowalls with what the company says is an improved LED engine. The new OVL series reaches a brightness level that is 20 percent higher than competing systems, according to the company, without shortening the projection system's lifetime.
The OVL videowall family is offered in a 4:3 aspect ratio, with screen sizes up to 80 inches.
Like Barco's 16:9 LED videowalls, the new OVL series has a heat management system based on liquid cooling technology, which brings the LED temperature down to an optimal level. This contributes to a significantly longer lifetime for the projection system, amounting to 80,000 hours of continuous operation in eco-mode, Barco officials said. It's the liquid cooling that makes it possible to boost the OVL's brightness level by up to 20 percent. Conversely, it's possible to further prolong the system's lifetime by lowering the brightness level, in which case the liquid cooling counteracts LED aging effects.
OVL videowalls can also save up to 30 percent of the power of other LED-based systems, according to the company. Barco says it achieves this by basing the OVL's color and brightness adjustment on smart power management, not on optical dimming.
Barco's OVL rear projectors come with Sense6, a sensor technology that coordinates across multiple rear-projection modules to provide brightness and color stability over time and across the entire videowall 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, according to the company.
Barco said the OVL videowall completes its range of LED-based systems, which also includes the 16:9 OL videowalls the company launched in 2009.
