Giant digiLED speedway display ‘is bigger than 4,300 TVs’

A speedway track in the US has installed 2,135 sq metres of digiLED’s Vision Ultra panels.

Texas Motor Speedway’s (TMS) Big Hoss TV, which replaced a screen erected in 2014, stands 11 storeys high and comprises more than 8.2 million pixels.

The display area is the equivalent of 4,331 42” TVs, making it one of the largest screens in the world.

A key requirement for the project was to reuse the existing steel structure. This allowed the original power supplies to be repurposed and reduced the display’s environmental impact by obviating the need for TMS to purchase about 15 tonnes of steel.

The system was built, tested and shipped within 60 days, a feat made possible by reuse of the steel structure, but digiLED still put it through intense testing, including “torture” testing to over 160F for three hours at a time.

The Vision Ultra’s unique cabinet design also helped integrator GoVision install the display in five weeks.

In the warm and often dry location, fans and filters had been an issue for the original Big Hoss TV. The Vision Ultra panels use passive cooling rather than fans, while an aluminium backing provides enhanced thermal management. These features mean that the displays require less maintenance and are recyclable at the end of their life.

The panels offer 10,000 nits of brightness, ensuring that they are visible even in direct sun.

The display was installed in time to wow fans at the first race of the season – the Autotrader EchoPark Automotive 400 NASCAR Playoff Weekend – displaying highlights, statistics and advertising content.
