UBI Research estimates that the OLED lighting market will take off in 2015, and will grow to reach $4.7 billion in revenue by 2020. According to UBI within three years a 100x100 mm OLED lighting panel will cost under $5 to produce. This is assuming a large substrate (1270x1270 mm), a fast production process and a tandem structure.
In such a scenario, the largest cost (over 80%) will be for the OLED materials. This means that at that stage companies will put most of their focus on lowering the material usage and cheaper OLED materials.
