Barco unveils color-stable, LED-lit rear-projection videowall display

Barco has announced its new series of LED-lit rear-projection displays. The full HD (1920x1080) LED-based videowall system features low-maintenance and saturated colors. The OL video wall series also features the company’s unique Sense6 color calibration and stabilization technology. The LED-based projection series consists of the rear-accessible OL and front-accessible OLF videowalls. During the introduction phase, both are available as 127cm (50in) and 179cm (70in) screen sizes. The OL and OLF videowalls have a wide LED color gamut, which exceeds the EBU standard, and present no signs of color break-up.

The OL and OLF videowalls have been designed for an entirely maintenance-free operation over several years, with a guaranteed LED lifetime of 55,000 hours and a five-year service-free runtime. There is also no need for consumables, such as color wheel or mercury lamps. As proven with the current OV-D2 product line, Sense6 provides brightness and color stability over time and across the entire videowall screen. It also continuously measures brightness and color and adjusts the color space to provide an image that is most convenient for the human eye.

As a result of the small depth of the projection modules, the OL and OLF videowalls are ideally suited for installation in confined spaces. A rugged design makes the videowalls perfect for traffic control rooms. After installation Sense6 automatically keeps all projection modules in tune to compensate for the inherent color shift of LEDs during their lifetime. Additionally, the Barco control manager software keeps track of the health status and allows the user to configure the uniformity and health status in an easy way. The software exposes an API which allows it to be integrated into larger device management applications.
