Samsung readies display production line

Posted: 22 Nov 2005     Print Version  Bookmark and Share

Samsung SDI Co., the world's largest plasma display panel maker, said it will invest more than $450 million to build a fourth-generation OLED (organic light-emitting diode) production line.

The company said it will break ground next month for the active-matrix OLED line at its PDP plant in Cheonan. Volume production will start in January 2007, producing 20 million mobile phone displays annually.

"The 4th-generation OLED is the industry's first ever to use [low-temperature polysilicon] as a base material, Samsung claimed in a statement.

Samsung plans to increase annual capacity to 50 million units by 2008 as mobile TV phones drive demand for high-resolution mobile displays.

While TFT-LCD technology currently represents more than 50 percent of the small display market for mobile phones, higher-resolution, low-power AM OLED technology is emerging as a competitor. AM OLED can switch pixels 1,000 times faster than TFT-LCD technology, fast enough to render moving images without ghosting.

Samsung SDI began producing "passive matrix" OLEDs in 2002 and became the top producer of mobile displays with a market share of 44 percent last year. The company's plasma display shipments for 2005 are expected to reach 2.2 million units.

According to the market researchers Display Search, the world OLED market is expected to grow to $4.55 billion by 2008.
