Flexible multitouch electroluminescent display

A method for using a display to present writing on the display comprising:

• a) providing a touch sensitive EL display having:
• i) a flexible substrate;
• ii) one or more power busses disposed over the substrate;
• iii) one or more EL elements disposed over the substrate for emitting light in response to an electrical signal;
• and
• iv) a first 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 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;
• b) providing 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 display that have been touched wherein each touch signal includes a location component and a force component;
• and
• c) a user causing a physical object to touch the display to provide writing on the display and the controller in response to the user touching the display providing touch signals representing the writing by the user and in response to the touch signals providing control signals causing the display to present the writing.
