IMO, I think this is just gimmickry. For one thing, now matter how
thin you make the screen, you still have to get sound out of it somehow, and it's a consequence of acoustic physics that the smaller the cabinet, the tinnier the sound. So, the thinner you make the screen, the more problems you have getting decent sound out of it, and the more necessary it becomes to use an external unit to produce it. Really, when they give the power consumption of thin screens, they ought to add something for the use of an external sound source.

I suppose there's always electrostatic speaker technology ...
Incidentally, I should clarify that when I called it gimmickry, I meant as a home TV. I can see that there might be great uses for such technology in multi-screen displays at rock concerts, etc, it's just it's value as a display for home video and TV that I was questioning.

They produced quite a good sound and were less than 1cm thick. Not on par with a decent set of speakers though, I would agree. I have not seen them advertsed for ages, but perhaps that technology has improved now and could be used with the very flat TV's to be hung on walls. Steve |

Many years ago, there was a patented system to produce sound from a flat,
well almost flat, surface. I seem to recall they used some weird idea of ultrasonic transducers fed with a modulated source that was supposed to be heard. The main issue as I recall was severe beaming and distortion effects as you moved around. So you don't get ought for nought as they say.
