2UE – Backlit LED TVs


Tracey was amazed at the number of acronyms used in the technology industry, especially when it comes to televisions. She was specifically talking about LG’s new Infinia series of LCDs, which use new backlit Liquid Emitting Diode, or LED, technology. In days gone by those little diodes were plastered at the back of the screen around the edges. These days they run across the back of the screen for a much better picture, and also means the television is a lot thinner than some other models out there

Had a few questions including one from Doug who is from Castle Hill in Sydney. He says he bought a digital radio recently, and the reception is terrible. You can my a digital radio aerial, which is directional, so you should be able to point it in different directions and get a better signal.

Trevor wondered about the internal workings of a 3D TV, which is slightly different from the technology used at the cinema for 3D movies. Televisions use active shutter technology, while movies usually use polaroid technology. At the end of the day, both technologies fool the eyes into thinking they are seeing one picture, when in fact they are being shown two different images. However, they’re being shown so quickly your eye can’t tell the difference and the glasses mean you see the picture in all its 3D glory.

Steve bought a Sony Ericson Xperia phone and was wondering if he could sync his iTunes with the Android-based handset. There are some programs out there that claim to be able to do it, including a beta version here: http://www.doubletwist.com/dt/Home/Index.dt.

Jan bought a digital radio, but it has a 10 second delay. She finds it a annoying that when she has her other radios on around the house, there is a noticeable lag with this one. I suggest that she find a nice big pair of speakers and turn her other radios off!
