RGB Laser ODL-821

An 80-inch rear-projection cube for round-the-clock control rooms

The Barco RGB Laser ODL-821 is an 80-inch rear-projection video wall cube built for operations centres that need screens running around the clock. Each unit measures 1,760 mm wide, 990 mm high and 730 mm deep, and several cubes join to form a larger wall. Its light comes from red, green and blue lasers rather than LED-lit modules, and the manufacturer identifies this laser engine as the basis for its brightness and colour performance.

Brightness, light source life and power by mode

The cube offers three operating modes. Choose the one that matches how bright your room is and how long you need the light source to last:

• Boost: 500 cd/m², 60,000 hours light source life, 260 W
• Normal: 390 cd/m², 125,000 hours light source life, 200 W
• Eco: 195 cd/m², 125,000 hours light source life, 120 W

The manufacturer rates the cube at 1.5 times the brightness of mainstream 80-inch LED-lit rear-projection cubes. The light source is rated at more than 125,000 hours in both normal and eco mode. The laser banks, power supply drivers, inputs and external power supply are all redundant, which the manufacturer lists as protection for uptime.

Colour, contrast and uniformity across the wall

The DLP engine delivers Full HD resolution at 1920 x 1080 pixels and a contrast ratio of 1800:1. Colour reaches up to 170% of the Rec.709 colour triangle, and customised white points can be set. Brightness uniformity is typically above 95% at ANSI 9 and above 90% at ANSI 13. Sense X automatic calibration supports colour stability, and the screen gap is 1.2 mm horizontally and 0.8 mm vertically at 25°C. The 30-degree half-gain viewing angle, both horizontal and vertical, is the figure to test against your seating layout. Using 80-inch cubes also means fewer seams per square metre than a wall built from smaller cubes.

Where the ODL-821 fits in Qatar

Three scenarios show how the cube suits the sites that buy it:

• A transport operations room in Doha showing traffic feeds and incident maps for a shift team that works through the night.
• A utility dispatch floor in Mesaieed or Ras Laffan where a wall of cubes presents plant status to operators around the clock, linked to existing software through the web service API.
• A security control room in West Bay or The Pearl monitoring camera feeds, with clearance behind the wall so technicians can reach it from the rear.

Planning the installation: rear access, heat and power

Before ordering, plan for the following:

• Rear access only, so keep a service corridor behind the wall and allow for the 730 mm depth.
• A projection module of 65.5 kg and a 1 m support frame of 42 kg, so confirm floor and wall loading.
• An operating range of 10°C to 40°C and up to 80% humidity, non-condensing, which means an air-conditioned room through Qatar summers.
• Heat output of 390 BTU/h in eco, 680 BTU/h typical and 860 BTU/h maximum, for cooling calculations.
• Power input of 100 to 240 VAC, 50 to 60 Hz, with draw of 120 W in eco and 200 W in normal mode.
