Samsung said a 110-inch TV that has four times the resolution of standard high-definition TVs is going on sale for about $150,000 in South Korea.

The launch Monday of the giant television set reflects global TV makers' move toward ultra-HD TVs as manufacturing bigger TVs using OLED proves too costly.

Last year, Samsung and rival LG Electronics, the world's top two TV makers, touted OLED as the future of TV. OLED screens are ultrathin and can display images with enhanced clarity and deeper colour saturation.

But Samsung and LG failed to make OLED TVs a mainstream option that would replace LCD television sets and are still struggling to mass produce larger and affordable TVs with OLED. Meanwhile, Japanese media reported last week that Sony Corp. and Panasonic Corp. decided to end their OLED partnership.

Demand expected to rise

Demand for U-HD TVs is expected to rise despite dearth of content while its price will likely come down faster than that of the OLED TVs. Much of the growth is forecast to come from China, a major market for the South Korean TV makers. Chinese TV makers have been making a push into the U-HD TV market as well.

According to NPD DisplaySearch, global sales of ultra-HD TV sets will surge from 1.3 million this year to 23 million in 2017. More than half of the shipments will be taken by Chinese companies between 2013 and 2017, according to NPD.

While Chinese TV makers have been seeking to boost sales of U-HD TVs with a lower price and a smaller size, Samsung's strategy is to go bigger with a higher price tag. Samsung's 110-inch U-HD TV measures 2.6 metres by 1.8 metres. It will be available in China, the Middle East and Europe. In South Korea, the TV is priced at 160 million won ($152,000 US) while prices in other countries vary.

Samsung said it received 10 orders for the latest premium TVs from the Middle East. Previously, the largest U-HD TV made by Samsung was 85 inches measured diagonally.

The ultra-HD TVs, whose picture resolution is four times greater than that of a standard 1080 pixel HD TV display, are also known as "4K" because their horizontal resolution is roughly 4,000 pixels.
