Patent attributes
A display device including a touch sensitive EL display having a flexible substrate; one or more power busses and one or more EL elements disposed over the flexible substrate; and a plurality of distributed chiplets 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 touch sensitive areas; each chiplet connected to one or more of the power busses and one or more of the EL elements for modulating power from the power busses to the EL elements in response to a control signal; and 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.
