Alternating　current　(AC)　driven　quantum　dots　(QDs)　light-emitting　diodes　have　attracted　widespread　attention　due　to　their　unique　optoelectronic　performance.　An　AC-driven　device　with　an　interdigital　electrode　structure　is　proposed.　The　devices　exhibit　AC　electroluminescence　(EL)　with　driving　frequency　and　different　frequency　responses　due　to　the　introduction　of　P(VDF-TrFE-CFE).　The　optical　and　electrical　characteristics　of　the　device　under　various　applied　voltages　and　driving　frequencies　are　studied.　Unlike　the　conventional　driving　mode　where　carriers　are　continuously　injected　into　the　device,　the　carriers　undergo　periodic　motion　under　an　AC　field.　Therefore,　there　exists　an　optimal　driving　frequency　that　maximizes　the　EL　intensity　of　the　device.　Based　on　the　experimental　results,　the　operational　mechanism　of　the　device　is　analyzed,　and　a　carrier　transport　model　is　proposed　to　elucidate　the　underlying　factors　contributing　to　the　presence　of　an　optimal　driving　frequency.　Moreover,　a　model　for　the　device　is　proposed　and　its　accuracy　is　verified.　From　a　circuit　perspective,　the　EL　behavior　of　devices　at　various　driving　frequencies　is　analyzed,　thereby　further　confirming　the　accuracy　of　the　proposed　device　working　mechanism.　We　believe　the　work　can　provide　guidance　for　obtaining　advanced　QD-based　light-emitting　technology.
