- marcan_42 7y agoLCD panels can be active dark or active light depending on how the polarizer is oriented and the specific display technology used, so it is not useful to blanket claim they slightly go either way, it varies. The linked article only took two samples (probably both TN panels which are generally active black) with unknown error margins, i.e. it is not a scientific study of how much power LCDs use in general. Let's just say there is no significant difference between white and black for LCDs in general.
