The　color　converting　film　(CCF)　is　first　fabricated　by　the　inkjet　printing　technology　with　the　drop-on-demand　advantage　in　the　paper,　the　volume　ratio　of　the　red　quantum-dots　(QDs)　over　green　QDs　is　1:12.9　at　balanced　intensity,　and　each　subpixel　of　the　CCF　is　sprayed　with　five　droplets　with　each　volume　of　48　pL.　The　CCF　has　been　equipped　in　the　corresponding　liquid　crystal　display　(LCD)　module.　In　theory,　the　optical　efficiency　of　the　CCF　mainly　depends　on　the　quantum　yield　of　QDs,　therefore,　and　the　total　optical　efficiency　can　improve　by　2.4　times.　The　LCD　module　sample　has　been　tested　to　verify　the　performance.　Experimental　results　show　that　the　color　gamut　reaches　131.4%　NTSC　in　CIE　1931,　the　total　optical　efficiency　is　20%.　Comparing　with　the　wide　color　gamut　backlight　module　with　QDEF,　the　color　gamut　improves　by　16.4%　NTSC,　the　total　optical　efficiency　improves　by　2.1　times,　and　the　average　color　crosstalk　ratio　decreases　by　4.21%　under　the　condition　that　the　misaligned　size　is　larger　than　the　width　of　the　black　matrix.　Our　method　provides　theoretical　guidance　to　realize　high-performance　LCDs.　©　2009-2012　IEEE.
