The world's number two television maker behind Samsung Electronics said its January-March profit was $816 million, up 82 percent from a year ago and in line with its estimate earlier in April.

Revenue rose 9.7 percent which was what the company thought it would get.

"We expect a high-single digit increase in revenue in Q2 versus the previous quarter," LG said in its earnings document.

LG's earnings will improve in 2017 as the firm's efforts to boost sales of high-end appliances and television products increase margins.

The mobile division's losses meanwhile are expected to narrow as its flagship G6 smartphones were well-received by critics.

LG's appliance division was boosted by demand for high-end products such as washers and refrigerators. Adding new features such as internet-of-things capabilities on the products will further help margins, some analysts said.

LG's television business booked a $336.6 million profit, as higher panel costs were offset by growing demand for larger-sized televisions that offer bigger margins.

The firm's mobile division reported a $176,386 operating loss for the quarter, its eighth-straight quarter in the red, with the G6 only having begun selling in March.

Analysts said ahead of LG's earnings announcement the firm likely saw improved sales of its mid-to-low tier products in markets such as the United States.
