The company swung to a net profit of Won242.5 billion ($213m) in the January-March period, from a Won15.8 billion net loss a year earlier. Operating profit more than trebled to Won448.2 billion while sales fell 7.1 per cent to Won12.2 trillion.
Overall profitability was bolstered by strong sales of its 3D TVs and internet-connected TVs, a business in which it dominates globally with rival Samsung, taking market share from Japanese rivals such as Sony and Panasonic.
LG plans to boost sales further through introducing higher-end TVs using organic light-emitting diode technology. It also aims to increase LCD TV sales this year by about 20 per cent to 30 million units, seeking to become the largest seller of 3D TVs by capturing about a quarter of the market.
