MediaTek could control over a 50% share of the smartphone-use touchscreen controller IC market in China after the Taiwan-based design house officially merges with fellow company MStar Semiconductor on February 1, 2014, according to industry sources.

　　MediaTek currently accounts for over 20% of China's smartphone touch controller segment through its affiliated company, Goodix Technology, which has been able to ramp up its market share by shipping IC parts in pair with MediaTek's smartphone solutions, the sources noted.

　　MStar, which is believed to be able to ship tens of millions of touchscreen controller ICs for feature phone and smartphone applications a month, has also maintained an over 20% share in touch controller IC markets in China and other emerging markets, revealed the sources.

　　A consolidation of the touch controller units of MStar and Goodix will add more pressure on other rival IC design houses, stated the sources.
