Samsung Electronics Co. (005930.SE) on Thursday unveiled a new tablet computing device equipped with an advanced display technology, as part of the push to develop a broader range of products using the company's ultra-thin panel for larger mobile products, touted as the key feature of its flagship smartphones.

Samsung, the world's second-largest handset maker after Nokia Corp. and the largest maker of TV sets, memory chips for computers and other digital gadgets, as well as flat-panel screens for many products, revealed the new 7.7-inch Galaxy Tab using its active-matrix organic light-emitting diode, or AM-OLED, display, which is more energy efficient than the typical smartphone screen, at the 2011 IFA trade show in Berlin.

The 335-gram Galaxy Tab will run Google Inc.'s (GOOG) upgraded Android operating system, called honeycomb, and uses a dual-core 1.4-gigahertz processor, Samsung said. The device also has a 32 gigabyte memory and is equipped with advanced mobile network technology called long-term evolution, or LTE, which offers faster download speeds than the current third-generation platform, allowing users faster access to TV programs, movies and video conferencing.

Samsung launched its first 7-inch Galaxy Tab in 2010 to better compete with rival Apple Inc. (AAPL), which is currently engaged in a broad legal fight with the Korean electronics giant around the globe, including in South Korea, Germany and Japan. Apple fired the first shot in the U.S. in April by filing a patent complaint against Samsung, claiming the electronics company "slavishly" copied its iPad and iPhone.

Samsung Mobile Display, a joint venture between Samsung Electronics and Samsung SDI Co. (006400.SE), supplies the new display technology to Samsung and other global handset makers.
