SEOUL, South Korea – 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 color saturation.

But Samsung and LG failed to make OLED TVs a mainstream that would replace the 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 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.

Previously, the largest U-HD TV made by Samsung was 85 inches measured diagonally.
