Ongoing　research　is　dedicated　to　tackling　the　trade-off　between　out-coupling　efficiency,　transparency,　and　conductivity　for　transparent　conductive　electrodes　(TCEs),　owing　to　their　continuously　increasing　application　in　smartphones/watches,　augmented/virtual　reality,　and　naked　eye　3D　projection.　Herein,　an　aluminum　substrate-mediated　hybrid　plasmon　mode　is　deliberately　embedded　in　solution-processed　organic　light-emitting　diode　(SOLED).　The　created　TCE　with　a　6-nm-Al　film-mediated　indium　tin　oxide　(ITO)　displays　an　average　transmittance　of　88.3%,　an　average　ultra-low　haze　of　0.2%,　and　a　sheet　resistance　of　9.5　omega　sq-1,　surpassing　commercial　ITO　substrates.　By　precisely　controlling　the　geometry　of　this　aluminium　film/dielectric　spacer/silver　nanoparticle　(Al　film-TAPC-Ag　NP)　coupled　system,　a　hybrid　dipolar,　and　quadrupolar　mode　is　required,　providing　further　enhanced　scattering　strength　and　plasmon　coupling　effect　in　the　resultant　OLED.　These　Al　film-TAPC-Ag　NP　system　mediated　SOLEDs　display　improved　decay　rate　of　triplet　excitons,　elevated　electroluminescence　out-coupling　efficiency,　and　suppressed　waveguide　confinement.　Consequently,　enhanced　stability　by　10%　after　580　h　storage　without　encapsulation,　forward-directed　emission　with　a　+/-　70　degrees　light-emitting　angle,　and　a　22%　current　efficiency　enhancement　are　simultaneously　realized,　compared　with　conventional　SOLEDs.　This　work　presents　new　opportunities　for　LED　design　and　for　the　implementation　of　solution-processed　LEDs　in　large-area　high-performance　displays.　A　hybrid　plasmon　mode　for　high-performing　solution-processed　OLED　is　presented.　By　coupling　silver　nanoparticles　to　a　dielectric　layer　mediated　aluminum　film,　the　resulting　emitter　displays　an　improved　decay　rate　of　triplet　excitons,　elevated　electroluminescence　out-coupling　efficiency,　and　suppressed　waveguide　confinement.　This　approach　has　the　potential　for　applications　in　various　optoelectronic　devices,　including　light-emitting　diodes　and　photovoltaic　devices.　image
