LG is set to unveil an internet-connected TV running the "webOS" operating system - an important move as the Korean company looks to dominate the nascent smart-TV market.
The TV will be showcased at the Consumer Electronics Show, which begins in Las Vegas on January 6, according to a report in The Wall Street Journal.
LG bought webOS from Hewlett-Packard in February 2012, saying at the time that it wanted its own operating system. Its devices currently run Google's Android software.
Hewlett-Packard earlier used webOS to power a tablet and some smartphone models which failed to compete with the likes of Apple's iPhones.
A source told The Wall Street Journal the operating system's interface would retain the "cards" system it had on mobile devices - a stack of pop-ups allowing users to navigate multiple applications.
The source said the operating system may later be used to run other LG devices, including smartphones.
LG is the world's second-largest TV manufacturer behind Samsung. Both companies are expected to unveil massive curved TVs, measuring more than 100 inches diagonally, at the Consumer Electronics Show.
Samsung is working on its own competing operating system for smart-TVs, called Tizen.
