Prototypes of the large panels, which promise less power consumption, thinner profiles, and perfect response times, were tested and approved earlier this year.
While Samsung has ditched its existing Fine Metal Mask (FMM) process in favour of Small Mask Scanning (SMS) to create the large-screen OLED TV, LG has used white OLED with colour filters to create the prototype.
The TVs are expensive to produce so a pilot-run is expected to launch in the summer followed by the launch of more units by year end. Sources suggest that the two companies plan to mass-produce the TVs by 2014.
