Novel displays glow on their own, stretch battery lives and are super thin
TAIPEI/SEOUL - A new generation of super-thin, power-sipping displays is making its way to the market, stretching battery lives to new limits and perhaps one day posing a challenge to heavier, energy-gobbling LCDs.
New screens that glow on their own are taking on their clunkier liquid crystal display rivals — which require powerful backlighting — by producing sharper video images for smartphones, game consoles and portable media players.
But industry watchers say it will be years before a clear winner — if any — emerges with the clout to outdo LCDs.
Organic light-emitting diode (OLED) and bi-stable technologies are the most likely challengers to LCDs.
An OLED screen uses as much as 40 percent less power than a comparable LCD and could be twice as thin because it does not need backlighting.
These technologies are already being used in some smaller portable devices, such as music players from Samsung Electronics Co. Ltd. and Reigncom Ltd. and a thin mobile phone from Kyocera.
And Sony Corp. plans to sell small-sized TVs using the OLED technology later this year.
“In hand-held devices, display consumes power most. It’s all about power and then maybe brightness,” said Lehman Brothers analyst James Kim in South Korea.
Analysts reckon Apple’s iPhone, which launched in the United States on Friday, may end up using more energy-efficient screens, such as OLED, given the short battery life of its pilot models with LCD screens.
“It makes sense (for Apple) to move to OLED screens. They are working to improve the battery issue,” said Kim Woon-ho, an analyst at Prudential Investment & Securities.
