A method of forming a conformal electronic scanning array (ESA) is disclosed. The ESA is formed using rolling techniques similar to those used in forming LCD displays. If the layers forming the ESA are made of substantially transparent materials, the ESA may be applied to an outer surface of a display, such as a flexible display. The ESA may also be applied to a window or other non-planar surface such as an outer surface of a vehicle, or may be integrated into a computer display.
