Samsung looks for global smartphone sales to hit 500 million units in 2012This article contains unofficial information.
The Display manufacturer is a 50-50 joint venture between Samsung Electronics and Samsung SDI and expects touchscreens to account for 50% of the sales of major portable devices by 2013. In turn, that growth would lead to the use of organic light-emitting diode (OLED) displays in 50% of all mobile phones in 5 years. OLED is considered the next generation display form that would allow for thinner devices with sharper images than the other forms of displays currently in use.
