Chinese firms show off cutting-edge products at tech show

Steve Koenig, director of Industry Analysis of the Consumer Electronics Association, admitted that Chinese smartphone brands are putting pressure to their global competitors.

Xiaomi alone sold 61 million units in 2014, with 70 percent of the sales generated online. Its latest phone, Mi5, is equipped with a 5.7-inch screen and a 20.7-megapixel camera, signaling that Chinese brands are not just focused on making cheap phones, but on quite sophisticated devices, Koenig said.

Large TV screens are another category dominated by Chinese manufacturers.

At the expo, the Guinness Book of World Records had to take a measurement and confirmed that TCL's 110-inch 4K curved screen is slightly bigger than a similar product of Samsung.

Meanwhile, Haier, China's leading household electrical appliances maker, and American company Roku Inc. announced their new Haier Roku TV, which combines Haier's excellent picture quality and slim bezel designs with the simple and easy-to-use Roku streaming experience that gives consumers access to more than 2,000 streaming channels, the largest lineup of streaming channels available on a smart TV.

Hisense, another Chinese TV manufacturer, also unveiled its latest HDTV set, the 100-inch VIDAA Max Laser Cinema TV.

As more Chinese companies would like to invest heavily on research and development, most of them are going farther in the global market.

Lin Lan, vice president of Hisense, said his company's market share in North America rose to 3.4 percent last year from 1.1 percent in 2013, adding that Hisense sold more than 2 million TVs in North America in 2014.
