"active-matrix displays of organic thin-film transistors/ OLEDs vertically sacked for higher active area, luminance, resolution, aperture ratio... all-dry discrete preparation-multilayer lamination separately prepares each conformable functional layer, laminates them together avoiding chemical/ physical damage... 83% pixel aperture ratio, 71% aperture ratio, can integrate modern microelectronic photolithography/ etching into skin display, allowing mass production, stripped from rigid substrates... portable/ wearable electronics"
