LeTV Holdings Co Ltd will sell its smartphones in the United States later this year, challenging Apple Inc's iPhone, the company said on Tuesday.

The Beijing-based technology company, known for its online video-streaming services, unveiled three types of handsets in a bid to take on the iPhone 6 Plus and Mi Note, produced by another Chinese smartphone maker, Xiaomi Corp.

LeTV plans to offer Internet TV and video-streaming services in the US later this year.
