The rollout of OLED televisions has been slower than industry expectations due to high manufacturing costs and a lack of technology breakthroughs, according to a new report.

The forecast of OLED revenue for 2014 has been downgraded from over $1 billion to $795 million in a report from industry body NPD DisplaySearch.

OLED is still much more expensive than LCD to manufacture and a lack of shipments combined with low yields of OLED materials will keep the price high for the foreseeable time, NPD says.

"The OLED material industry and related investors are justifiably worried about where the OLED material market is headed in the near future," said Jimmy Kim, senior analyst for display materials and LED for NPD DisplaySearch. (Source: CNET.com)
