The　density　dynamic　adjustment　algorithm　(DDAA)　is　designed　to　efficiently　promote　the　uniformity　of　the　integrated　backlight　module　(IBLM)　by　adjusting　the　microstructures’　distribution　on　the　compound　optical　film　(COF),　in　which　the　COF　is　constructed　in　the　SolidWorks　and　simulated　in　the　TracePro.　In　order　to　demonstrate　the　universality　of　the　proposed　algorithm,　the　initial　distribution　is　allocated　by　the　Bezier　curve　instead　of　an　empirical　value.　Simulation　results　maintains　that　the　uniformity　of　the　IBLM　reaches　over　90%　only　after　four　rounds.　Moreover,　the　vertical　and　horizontal　full　width　at　half　maximum　of　angular　intensity　are　collimated　to　24　deg　and　14　deg,　respectively.　Compared　with　the　current　industry　requirement,　the　IBLM　has　an　85%　higher　luminance　uniformity　of　the　emerging　light,　which　demonstrate　the　feasibility　and　universality　of　the　proposed　algorithm.　©　2017　Elsevier　Ltd
