Computer screens of the future could offer sound as well as vision, eliminating the need for separate loud speakers.
A British company called NXT has found a way to turn a computer display into a speaker, without interfering with the quality of the picture.
Its SoundVu technology has already been built into two models by Japanese electronics giant NEC.
NXT says it also could be used other products like flat screen televisions and is talking to several electronics manufacturers about the technology.
The Cambridge-based firm is best known for creating the technology behind flat panel speakers.
It is now turning its attention to the world of computing, capitalising on the trend to turn home PCs into digital entertainment centres.
