LED effective in acne treatment

Acne vulgaris is a common disease, accounting for over 30 percent of visits to dermatology clinics. There is a range of treatments but some are accompanied by side effects such as a burning sensation and resistance to antibiotics. The search for alternative treatments thus continues, and light emitting diode (LED) has been recently touted.

A research team led by Prof. Suh Dae-hun at Seoul National University Hospital and Prof. Lee Jee-bum at Chonnam National University Hospital showed through clinical research that it is really effective. “Blue and red lights have been reported to have beneficial effects for acne through distinct mechanisms. However, there has been no double blind randomized study for a combination of blue and red light emitting diode phototherapy,” they noted in the research.

Irradiation from blue visible light has been known to combat acne through a process that leads to bacterial destruction, while red light has also been reported to have anti-inflammatory properties. However, this wasn’t backed up by clinical tests.

LG and Osram agree to settle LED patent suit

LG Electronics and LG Innotek, the electronics arms of Korean conglomerate LG, said Friday they have agreed to drop all light-emitting diode (LED) patent litigations with Osram GmbH, the LED unit of Siemens AG.

As part of the Oct. 31 settlement, the companies also agreed on a license agreement for their LED patent portfolios, settling patent suits filed in countries including Korea, Germany and the United States, the LG affiliates said in a press release.

The terms of the agreement were not disclosed.

“We are very much satisfied with the settlement reached. It is our long-standing policy to reach license agreements with other manufacturers of LED products,” said Aldo Kamper, chief executive officer of Osram Opto Semiconductors.

A new smart TV or a set-top box?

Daum Communications’ little black box set to spark new battle in digital arena as it promises to undercut rivals. As Samsung Electronics and LG Electronics vie for leadership in terms of smart TV sales, Web portal Daum Communications has chosen to pursue a new niche market by supplying platforms for the latest highly-convergent goggle boxes.

In front of dozens of reporters from Seoul at its newly established Daum Space. 1 building in Jeju Island, the Kosdaq-listed firm unveiled on Friday its new Daum TV, an Android-based operating system for smart TVs.

Despite existing amid a fog of confusing definitions, smart TVs offer Internet connectivity without the need to link up to a separate computer. They also tend to function more like smartphones running on apps rather than regular flat-screens. Regular TVs can be upgraded using a set-top box.
