When we were in Japan last year we noted that Sharp were doing some pretty interesting things with LCDs. One in particular was a way of superimposing a “parallax barrier” onto the LCD to make the source light separate into right and left directions.
Sounds dull but its key application – that two people, sitting on opposite sides of the room can watch two separate things on the same screen simultaneously – is pretty amazing. Interestingly it seems that Sharp is about to unleash that technology to the masses with the first dual display screen set roll of its production lines later this year.
“Take a typical family where the mother likes to watch dramas and the father likes to watch baseball or soccer. Now they can watch them together on the same screen,” Mikio Katayama, head of Sharp’s LCD business, told a news conference.
The fundamental flaw though is that two separate audio channels delivered into a room at the same time might be tricky. So it is either headphones for one party, or more likely people will use the screen to watch TV and surf the web simultaneously. More info here
