We　report　a　novel　integrated　backlight　module　(IBLM),　which　is　composed　of　a　compound　optical　film　(COF)　and　a　light　guide　plate　(LGP)　without　any　microstructure.　The　COF　proposed　in　the　paper　comprises　functions　of　a　conventional　microstructure　that　adjusts　the　emergent　light　and　two　cross　brightness　enhancement　films　(BEF).　The　four　surfaces　of　the　LGP　are　coated　with　highly　reflective　film.　The　COF　can　not　only　adjust　the　distribution　of　the　output　light　by　varying　the　density　of　the　microstructure　on　the　COF,　but　also　can　collimate　the　two　cross-direction　lights　into　the　normal　direction.　The　horizontal　and　vertical　full　width　at　half　maxima　of　angular　intensity　of　the　IBLM　with　the　proposed　COF　for　the　optimum　are　of　14　and　24　deg,　respectively.　The　spatial　uniformity　and　total　optical　efficiency　of　the　IBLM　have　reached　85%　and　77.2%,　respectively.　The　optical　efficiency　has　been　increased　by　1.3　times　and　the　on-axis　luminance　has　improved　by　5.1　times　by　using　a　backlight　module　(BLM)　with　the　COF,　in　comparison　with　the　conventional　edge-lit　BLM　that　we　researched　[Appl.　Opt.　55,　1494　(2016)].　Most　importantly,　the　COF　only　needs　to　be　configured　with　a　relatively　low-cost　and　easily-manufactured　LGP;　therefore,　the　BLM　with　the　adopted　COF　can　be　further　developed　for　large-sized　application.　(C)　2016　Optical　Society　of　America
