NEW YORK (AP) — For flat-panel TVs, the choice for years has been between plasma and LCD. In the coming year, there'll be another choice, at least for those prepared to spend big.

LG Electronics Inc. says it's planning to sell a 55-inch set based on organic light-emitting diodes, or OLEDs. The Korean company is set to show it off at the International Consumer Electronics Show in Las Vegas, which starts Jan. 10.

Samsung Electronics Co., LG's Korean rival, will also reveal a nearly market-ready OLED TV at the show, according to three people with knowledge of the matter. They spoke on condition of anonymity because Samsung has yet to make an announcement. Its website says CES announcements will come Jan. 9.
