A closer look
The science fiction dream of invisible monitors is finally sitting in corporate boardrooms thanks to Transparent Conductive Oxides (TCOs). Traditional displays require opaque metal backplanes to blast electricity into the pixels. LG and other display pioneers swapped those metals for compounds like Indium Tin Oxide, a freak of material science that conducts electricity beautifully while remaining totally optically transparent. The result is a vibrant, high-definition OLED screen that flawlessly masquerades as a standard pane of window glass the exact second you turn it off.
