:-) It's ok - just cultivate an interest in all things emo/goth/death-metal and OLED is perfect. Seriously though, from the above linked article, While LCDs remain more power efficient for images with mostly full screen white content (like all text screens on a white background, for example), OLEDs are more power efficient for typical mixed image content because they are emissive displays so their power varies with the Average Picture Level (average Brightness) of the image content over the entire screen. For OLEDs, Black pixels and sub-pixels don’t use any power so screens with Black backgrounds are very power efficient for OLEDs. For LCDs the display power is fixed and independent of image content. Currently, OLED displays are more power efficient than LCDs for Average Pictures Levels of 65 percent or less, and LCDs are more power efficient for Average Picture Levels above 65 percent. Since both technologies are continuing to improve their power efficiencies, the crossover will continue to change with time. At peak brightness with a pure white screen, the iPhone 7's screen draws 1.08 watts, whereas the Galaxy Note 7's draws 1.8 watts. So if you keep your phone at peak brightness, I guess that's one metric where LCD beats OLED.
