The use of postsynaptic current to drive long-lasting luminescence holds a disruptive potential for harnessing the next-generation smart displays. Multiresponsive long afterglow emission can be achieved by integrating light-emitting polymers in electric spiked transistors trigged distinct presynaptic signals inputs. Here, we report highly effective organic transistor (LAOLET), whose operation relies on nanofloating gate architecture. Long with reconfigurable brightness and retention time is observed upon applying specific positive voltage spiked. Conversely, when negative stimulus applied, these LAOLETs function as click-on display. Interestingly, endowing device force sensing capabilities, it operate pressure sensor that emits green light subsequently controlled extrusion action.
