According to IDTechEx, the market for printed and flexible electronics in the automotive industry will grow from around $400 million in 2016 to over $5.5 billion in 2026. The market will be driven mostly by OLED technologies and in-mould electronics.
If we look at OLED specifically, the OLED automobile market will grow from around $150 million in 2016 to about $500 million in 2018. The OLED lighting market will still be small - only around $25 million in 2018. OLED displays will of course be much more popular.
