If you’re wondering how does Samsung’s Super AMOLED fare against the competition, DisplayMate has done a thorough analysis of the mobile displays. They’ve pitted the Super AMOLED against all available mobile displays and have found that although Super AMOLED boasts excellent viewing angle and improved power consumption, the colors are gaudy and over saturated when compared to a LCD.

However, despite its shortcomings DisplayMate says OLED is in its infancy and with the work Samsung is doing to improve the display, is commendable.
