LG Electronics' newest displays that marry two high-end technologies -- Ultra HD and OLED -- are moving closer to the marketplace.

The Korean electronics giant today announced that it will begin taking pre-orders for 65-inch and 77-inch Ultra HD OLED TVs later this week in Korea.

Pricing and availability of the curved Ultra HD OLED TVs will be announced in the coming weeks, but LG expects to make them available by year's end.

Mashable reported that the 65-inch display will cost 12 million won or $11,765, but LG officials said that any price tags attached to the displays are not official. LG's newest curved OLED display with regular high definition is priced at about $3,500.

The company made the announcement ahead of next week's IFA electronics show in Berlin. "LG is reinforcing the commitment made at (the Consumer Electronics Show), and confirmed throughout the year, to bring Ultra HD OLED TVs to market in Q3/Q4 of 2014," said Tim Alessi, LG's U.S. head of new product development, in a statement.

Ultra HD is also sometimes referred to as "4K," because the displays have nearly 4,000 pixels lined horizontally, delivering four times the resolution of current high definition TVs. And OLED (organic light-emitting diode) displays promise rich contrast and color saturation, beyond that of other technologies.

"As the next evolutionary step in display technology, OLED will play a major role in reshaping our industry. I feel confident when I say that 4K OLED is a bona fide game changer," said Hyun-hwoi Ha, president and CEO of LG's Home Entertainment Company in a statement.

"OLED's benefits are obvious," he said. "There's no deterioration in picture quality and issues such as image blurring, distortion and color leakage in curved LED units are simply non-existent on curved OLED TVs."

Both the 65-inch and 77-inch models have built-in Ultra Surround sound, designed with Harmon Kardon, and have a new Smart TV operating system based on WebOS, which LG acquired last year from Hewlett-Packard.

The 77-inch display and LG's WebOS each were chosen as among the best products at the Consumer Electronics Show in January by Reviewed.com.
