China-based Sigmaintell Consulting says that shipments of AMOLED-based smartphones slid 13.8% in China in the first half of 2017. A total of 37.4 million such phones were shipped, with the top two vendors being Oppo (13.8 million units) and Vivo (13 million units) accounting for 71% of the market.
Sigmaintell says that shipments fell compared to 2016 because some vendors (including Oppo) opted for in-cell LCD displays over OLED displays.
