A news article on the Business Korea website is suggesting that DisplaySearch is forecasting the sales of the global AM-OLED market to grow from US$10.34 billion in 2014 to US$23.07 billion in 2022. However, this wasn't the case between 2013 and 2014 when the market actually declined by 17%, industry opinion makers are expecting the market to rebound this year and see double-digit annual growth for the next 5 to 10 years.
It would appear that the main driver will be the rapid adoption of AM-OLED displays in the large area TV market. t is the TV market that is expected to grow at a particularly rapid pace.
