LG Electronics Co., a South Korean smartphone maker, on Thursday revealed its newest smartphone model, the G Pro 2, paving the way for the country's No. 2 tech giant to expand its share in the large display smartphone market. LG's phablet, a cross between a smartphone and tablet PC, boasts a 5.9-inch display, larger than its predecessor's 5.5-inch screen, and will compete with rival products such as the Galaxy Note series manufactured by Samsung Electronics Co., the world's largest maker of smartphones.
