The image surface is one of the most critical elements of a projection system, and a poorly informed choice can significantly reduce the expected performance of the chosen projector.

An acoustically transparent image surface serves an almost impossible dual role: in addition to presenting a great image, it must also present a minimal obstruction to sound from speakers placed behind the screen.

Three main methods exist to create acoustically transparent image surfaces

1. Micro perforation - typically PVC

2. Woven fabric - typically used with fibreglass threads

3. Knitted fabric - typically polyester

There is no ideal image surface; it is always a choice of which compromises will result in the best overall result for the project.

At Display Technologies, we noted that specifiers often struggle to understand exactly how to specify the right solution for their project. Given the proliferation of "exaggerated" product specifications in the market, this should come as no surprise.

We have invested in creating a dedicated laboratory at our factory in the UK, which allows us to test our image surfaces in detail, as well as many of those from competitors. The results were so divergent from the published specifications that we created this guide explaining our image surfaces in detail and giving specifiers all the information needed to deliver the best possible results when using DT screens on their projects.
