Pixelated　quantum-dot　color　conversion　film　(QDCCF)　is　attractive　for　next-generation,　high-pixel-density,　full-color　displays.　However,　how　to　achieve　white　balance　of　these　QD　converted　displays　puts　forward　a　new　challenge,　because　the　final　light-emitting　area　is　redefined　by　the　apertures　of　the　QD　formed　subpixels.　Based　on　this,　this　paper　presents　an　effective　white-balance　realization　approach　by　precisely　defining　an　asymmetric　aperture　ratio　among　three　primary-color　subpixels　of　the　QDCCF.　Based　on　the　measured　photoluminescence　characteristic　of　quantum-dot　photoresist　(QDPR),　the　theoretical　aperture　ratio　can　be　derived　by　the　spectral　radiation　energy　and　external　quantum　efficiency　(EQE)　of　QDCCFs　for　the　target　D65　white-balance　state.　A　bilayered　device　architecture,　combining　a　blue　mini-LED　backlight　and　a　pixelated　QDCCF,　was　simulated　and　experimentally　assembled　to　verify　the　theoretical　design.　The　simulated　chromatic　coordinates　obtained　from　the　QDCCF　precisely　agree　with　the　target　white-balance　point.　Experimental　patterning　and　pixelation　of　the　designed　QDCCF　were　achieved　by　a　precise　photolithography　process.　Measured　results　show　that　a　white-light　output　was　achieved　with　the　chromatic　coordinates　of　(0.2822,　0.2951)　and　the　color　gamut　of　115.09%　NTSC　(National　Television　System　Committee)　standard.　The　deviation　of　the　experimental　chromatic　coordinates　is　within　+/-　0.05　to　the　D65　standard　light　source.　The　proposed　white-balance　realization　approach　featured　by　the　aperture　adjustable　subpixels　of　a　chromatic　QDCCF　may　open　up　a　new　route　for　color　reproduction　in　emerging　display　technologies.
