LCD technology is rapidly moving to dominate the worldwide digital TV market, new research reveals.

Analyst firm In-Stat predicts that LCD will have almost 75 per cent of the market in 2011, and that plasma will fade to less than 15 per cent.

"US consumers exhibited reduced interest in HD TVs,” said In-Stat analyst Michael Inouye.

"Respondents most interested in HD TVs, for instance, fell from 17 per cent in 2006 to 13 per cent in 2007, while those least interested increased 12 percentage points in 2007 to 65 per cent.

"International respondents, however, exhibited more interest in HD TVs. Consumers in France and South Korea, in particular, demonstrated strong levels of interest at 44 per cent and 40 per cent high-interest respectively."

According to the In-Stat research, worldwide digital TV unit shipments are expected to grow from 68 million units in 2006 to over 144 million by 2011.

Total revenue is expected to grow from $71bn in 2006 to $76.7bn in 2011.
