Samsung develops a technology for AMOLED displays with multiple refresh rates

Samsung Display has developed a new technology that enables multiple refresh rates in AMOLED displays. The idea is that one can create several zones in the display, each with its own refresh rate.

Driving at low refresh rates helps reduce the power consumption of the display and the new technology will be useful in scenarios in which a part of the screen needs high refresh rates (like video content embedded inside a web page).
