The craze for 3D films has intensified off the back of the Avatar’s success and, as a result, manufacturers are finding it hard to keep up with the demand for 3D projectors.

Projector manufacturer Barco’s chief executive Eric Zele explained, “the challenge will not be on how many you can sell, it will be on how many you can make.” The fact remains that around 85 per cent of the world’s cinemas have yet to be fitted out with digital projectors, which means that the market potential for projector makers is enormous.

Dodona, a cinema research company, says that only around 15,000 cinema screens, from the 115,000 screens around the world, were fitted with digital projectors last year and Barco says it stands to make as must as EUR 150 million from its digital projectors this year alone.

The only thing standing in the way of these manufacturers is bottlenecks in supplies of the components that are needed to build projectors. Many smaller manufacturers of parts like printed circuit boards and optical devices, including projector lenses, have struggled to keep up with demand.

Overall though, it's fair to say that the future is bright for the digital projector market and that the sustained demand will encourage suppliers to up production levels.
