Patent ID: 8072437

Claim:
A display device comprising: a) a touch sensitive EL display having: i) a flexible substrate; ii) one or more power busses disposed over the flexible substrate; iii) one or more EL elements disposed over the flexible substrate for emitting light in response to an electrical signal; and iv) a first plurality of distributed chiplets, each having a separate chiplet substrate, arranged so that at least two chiplets are associated with each of a plurality of touch sensitive areas on the EL display and for sensing stress or strain associated with bending of the flexible substrate or the chiplet substrate to provide respective displacement signals corresponding to the corresponding touch sensitive areas wherein each chiplet is connected to one or more of the power busses and one or more of the EL elements for modulating power from the power busses in response to a corresponding control signal to provide an electrical signal to the one or more EL elements; and b) a controller for providing control signals to the chiplets in response to an input image signal and for receiving displacement signals from the chiplets and producing touch signals indicating the corresponding touch sensitive areas of the touch sensitive EL display that have been touched.
