Abstract
An optoelectronic device comprising a unit, which unit comprises: a plurality of resiliently flexible sheet components bonded together, the resiliently flexible sheet components comprising: (i) a first sheet component comprising at least a stack of layers defining an array of pixel electrodes and electrical circuitry for independently addressing each pixel electrodes via addressing conductors outside the array of pixel electrodes; and (ii) a second sheet component bonded to a top surface of the first sheet component; wherein the device further comprises one or more driver chips bonded to the first sheet component in a location underlying the second component and for electrical contact between said addressing conductors and terminals of said one or more driver chips; and wherein the thickness of material in the unit in the region of the one or more driver chips is substantially the same as the thickness of material in the unit in the region of the array.
