Hitachi Ltd indicated a roadmap of its ultrathin TV products at a flat-panel TV business presentaion Feb 8, 2008. According to the roadmap, the company will release 35mm-thick PDP TV product in 2009 and 10mm-thick or slimmer models in 2010 to 2012.

As for LCD TVs, Hitachi is already marketing the 35mm-thick "Wooo UT series" products (See related article). Following them, the company will launch 19mm-thick models in 2009 and 15mm-thick models in 2010 to 2012.

Although having introduced ultrathin LCD TVs ahead of PDP TVs in real, Hitachi indicated that it can make PDP TVs slimmer than LCD TVs in the future. Explaining why, the company said, "Unlike LCDs, PDPs don't require backlights because they emit light by themselves. We can make PDPs slimmer as they only require a panel and circuits. LCDs can be made no slimmer than around 15mm."

Regarding OLED panels, which are most likely to be applied for ultrathin TVs, Hitachi indicated its view saying, "We might be able to commercialize an OLED TV in 2010 to 2012."

To increase PDP light-emitting efficiency 2.3x as much in 2009

Hitachi insisted such reductions in thickness concern environment.

"Ultrathin TVs propose a new way of using them as a location-free product, but more significantly, they promote ecology by making transportation and packaging easier," Hitachi said. "Furthermore, power reduction is essential to realize ultrathin TVs in terms of heat design, and therefore, such TVs are directly related to ecology, in fact."

In an effort to lower PDP power consumption, Hitachi has reportedly been advancing a project to raise PDP light-emitting efficiency, introducing 40 engineers from its laboratory for roughly 18 months. Currently developing a panel with 2.3 times the current light-emitting efficiency, Hitachi will release TVs with half the current power consumption in 2009 to 2010, the company said.
