Despite　recent　remarkable　progress　in　multiple　synaptic　devices,　searching　for　artificial　synapses　with　new　functions　is　still　an　important　task　in　the　construction　of　artificial　neural　networks.　The　parallel　output　functionality　of　photoelectric　signals　in　artificial　synaptic　devices　is　interesting　and　desirable　as　on-chip　optoelectronic　interconnection　technology　allows　the　connections　between　neurons　weighted　by　current　and　light.　In　turn,　it　provides　degrees　of　freedom　and　reduces　circuit　lead　density　in　the　design　of　large-scale　neural　networks.　Hence,　for　the　first　time,　a　light-emitting　electrochemical　artificial　synapse　(LEEAS)　based　on　poly[2-methoxy-5-(2＇-ethylhexyloxy)-1,4-phenylene　vinylene]/poly　(ethylene　oxide)/lithium　salt　blends　with　dual　output　of　photoelectric　signals　was　developed　in　this　study.　The　electrochemical　redox　reaction　enables　the　device　to　achieve　synaptic　plasticity　in　biology　and　emulate　the　memory　enhancement　process,　high-pass　filtering　characteristic,　and　classical　Pavlov＇s　conditioned　reflex　experiment.　In　addition,　the　transient　luminescence　intensity　of　the　LEEAS　induced　by　identical　electric　spikes　exhibits　a　synaptic-like　potentiation　behavior.　Owing　to　the　combination　of　electroluminescence　(EL)　and　synaptic　memory　behavior,　an　LEEAS　array　exhibits　a　unique　image　display　and　storage　functions　that　can　memorize　displayed　images.　The　LEEAS　proposed　in　this　work　enriches　the　diversity　of　artificial　synapses,　promoting　the　diversified　design　and　development　of　next-generation　optoelectronic　hybrid　artificial　neural　networks.
