LG says 7 years before OLED drops to LCD prices

LG OLED TV.If you’ve been sitting on your next TV purchase for that glut of OLED TVs to flood the market, you shouldn’t. LG’s VP of OLED sales and marketing, Won Kim, says prices won’t come down to LCD levels until 2016. Seven years is a long way off, and so much can change that Kim might be wrong, but in any case, OLEDs won’t be reasonable anytime soon.

Kim’s statements came shortly after LG announced a 15-inch OLED TV for its Korean market at the end of this year. No announcement for the US market, and that’s sort of been the standard so far. Only Sony sells an OLED stateside, and it’s just 11-inches. So it’s not just market prices we’re waiting on – the whole system has to mature enough to even be able to deliver the product.

Kim did say we would see 40-inch OLEDs by something like 2012, but you can bet they’ll be expensive. Of course by then who’s to say LCDs and Plasmas won’t be nearly as good as an OLED? The “absolute black” that makes the OLED so attractive (among some other features) is nearly attainable now with dimming LED TVs. In seven year this generation of technology could come a long way.

Thin-Film Speakers Could Revolutionize Flat Panels

Say Goodbye to Speakers.When you buy a new TV it almost goes without saying that you’ll need new speakers. LCDs and plasmas gave back the 5-7 square feet that was once dedicated to cathode-ray tubes, but they pushed big built-in speakers out the door. The result: a gorgeous picture with tinny trash for sound.

Commercial and academic researchers are looking to change all that by putting the speaker in front of your screen. Emo Labs, a startup from Massachusetts, has created transparent membrane that could replace traditional cone speakers. The transparent film lays over your TV display and is then “driven” by two piezo-electric actuators. The actuators create the motion usually produced by a magnetic voice coil to create sound waves.

As you might imagine, laying a membrane over your picture does have its drawbacks. In its current form, the membrane nets a 4% loss in picture brightness. To be honest, that doesn’t seem so bad, especially as we get closer to the OLED revolution. With a 2,000,000:1 contrast ratio, 4% should hardly be noticeable.

As for price, you early adopters will see the worst of it. Emo Labs estimates their membranes will add a 10-15% premium onto existing flat-panel prices. For larger TVs, you’d probably be better off putting that money toward a powered subwoofer. For smaller sets, under 27″ perhaps, the membrane could be another way to save space.
