Panasonic Drops Plasma

Panasonic has announced it will discontinue production of plasma display panels (PDP) next month and close three factories that were building the HDTVs.

The company will stop selling plasma TVs for consumer use and PDP-related products for commercial use, such as Interactive Plasma Displays, with the current line of TVs. It expects to stop business operations at three of its display plants — the Amagasaki P3 Factory, the Amagasaki P5 Factory and the Amagasaki P4 Factory — by the end of March 2014.

Samsung and LG continue to produce plasma display televisions, but theirs are lower-end or entry-level models; they have generally put development dollars into LCD TVs, according to Paul Gray, a research analyst with NPD DisplaySearch.

“Samsung and [LG] were at best uncommitted to PDP,” Gray said in a blog post. And as for Panasonic, Gray said its “PDP research team had to counter every move in LCD and translate it to their technology…. Inevitably, they slowly lost ground.”

Since 2000, Panasonic has been the leading PDP maker. It led the global flat-panel display market by using PDP for large displays and LCD screens for small- and medium-sized displays. Only three years ago, Panasonic claimed 40% of the plasma display market.

In 2010, plasmaaccounted for 40% of flat panel TVs; this year, PDPs are expected to represent only 5% of the flat-panel market, according to according to market research firm NPD DisplaySearch.

Over the past two years, Panasonic has lost $15 billion through investments in flat-panel TV production, according to financial reports.

Plasma displays have increasingly lost market share to LCD TVs as they moved to LED backlights that narrowed the performance gap between the two technologies.

“With the rapid development of large-screen LCDs, and facing the severe price competition in the global market brought on by the Lehman Shock in September 2008, the company consolidated production in the Amagasaki P4 Factory, made a shift towards commercial applications and worked to improve the earnings of the business,” Panasonic said in a recent statement.

Panasonic will now focus its attention on “non-TV applications” and is moving to reduce its fixed costs for production of both plasma and LCD panels.

The move away from plasma HDTVs is reminiscent of the video tape wars of the 1970s and 1980s.

MIT Develops Inflatable Antenna

Satellites the size of shoe boxes, which are expected to one day allow researchers to explore space more efficiently, will soon have greater range.

MIT researchers have built and tested an inflatable antenna that can fold into such a satellite, then inflate in orbit to enable long range communications — from seven times the distance possible today.

The technology will let the small satellites, called CubeSats, move further into space and send valuable information to scientists back on earth.

“With this antenna, you could transmit from the moon, and even farther than that,” said Alessandra Babuscia, a researcher on the inflatable antenna team at MIT, in a statement. “This antenna is one of the cheapest and most economical solutions to the problem of communication. But all this research builds a set of options to allow the spacecraft … to fly in deep space.”

The MIT effort comes as engineers at the University of Michigan work on ways to propel such small spacecraft into interplanetary space. The team is building a plasma thruster that could fit in a 10-centimeter space and push a small satellite-bearing spacecraft into deep space.

The university researchers using superheated plasma that would push through a magnetic field to propel a CubeSat.

The MIT researchers are seeking to solve the communications problems and enable far-afield CubeSats to send data to and receive instructions from Earth.

The CubeSat devices cannot support radio dishes that are used today to let spacecraft communicate when far from Earth’s orbit.

The inflatable antennas significantly amplifies radio signals, allowing a CubeSat to transmit data back to Earth at a higher rate, according to the university.

MIT engineers have built two prototype antennae, each a meter wide, out of Mylar, which is a polyester film known for its strength and use as an electric insulator. One antenna was a cone shape, while the other looks more like a cylinder when inflated. Each fits into a 10-cubic-centimeter space within a CubeSat.

Each prototype contains a few grams of benzoic acid, which can be converted to a gas to inflate the antenna, MIT noted.

In testing, the cylindrical antenna performed “slightly better” than the cone shaped device, transmitting data 10 times faster, and seven times farther than existing CubeSat antennae.
