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.

Flexible optoelectronic devices

A method for forming electrical connections between electrical conductors is provided. The method includes depositing an anisotropic conductive bonding material (AC bonding material) on a first plurality of electrical conductors, sandwiching the AC bonding material between the first plurality of electrical conductors and a second plurality of electrical conductors, providing first and second cushions formed of a thermally resistive and elastic material, and applying heat and pressure to the second cushion to form the AC bond between the first and second plurality of conductors.

Method of bonding flexible printed circuits

A technique comprising: assembling together a front plane () comprising a first flexible substrate () supporting a display medium () and a backplane () comprising a second flexible substrate () supporting an array of electronic elements () for controlling said display medium; and creating an electrically conductive connection between first and second conductive elements () on opposing faces of the frontplane and backplane by sandwiching an electrically conductive structure () between the frontplane and backplane in the region of the first and second conductive elements, wherein the conductive structure is at least more flexible than the least flexible one of the front plane and backplane.

Assembling a flexible display

A touch sensitive active matrix display device is provided. The device includes a display fabricated on a first flexible substrate, said display having a viewing surface. The device further includes a touch sensitive sensor including a second flexible substrate, under said display. The touch sensor is operated by touching said viewing surface of said display, and said combined display and touch sensitive sensor is flexible.
