Samsung Electronics reported its fourth quarter net profit leaped 40 per cent compared to the same time a year earlier on strong sales of mobile phones, LCD panels aimed at the TV market, and memory chips used in Apple's iPod music players.
The South Korean technology giant said its fourth quarter sales expanded to 15.52 trillion Korean won ($US15.59 billion as of December 31, the end of the three month reporting period), up from 13.9 trillion won during the same time a year earlier.
The company's net profit rose to 2.56 trillion won, from 1.83 trillion won.
"The fourth quarter was one of the strongest fourth quarters that we've ever had," a senior vice-president on the Samsung's investor relations team, Woosik Chu, said.
The last three months of the year are the most important for technology companies because of strong consumer demand during December holidays.
The company's net income for the full year, however, declined 29 per cent to 7.64 trillion won from 10.79 trillion won in 2004, despite nearly flat sales of 57.46 trillion won in 2005, down a little from 57.63 trillion won.
