White-balance characteristic of quantum-dot backlight

Translated Abstract

In　order　to　realize　color　gamut　extension　and　white　balance　of　backlight　source　in　liquid　crystal　displays,this　paper　researches　light　mixing　theory　of　quantum-dot　backlight　in　CIE1931　chromaticity　system　by　using　Gaussian　curve　fitting　spectrum,and　establishes　spectral　function　model　of　quantum-dot　backlight　source,and　further　proposes　a　conversion　method　between　quantum-dot　spectrum　and　color　coordinates.First,based　on　maintaining　effective　spectral　information,the　complex　spectral　data　is　fitted　to　conform　to　the　superposition　of　Gaussian　function.Then,color　coordinate　calculated　by　CIE1931XYZ　system　is　used　to　solve　spectral　function　and　Gaussian　parameters.Finally,the　white　balance　of　backlight　source　can　be　achieved.Experimental　verification　achieves　the　spectral　power　function　and　analyses　the　color　characteristics　of　quantum-dot　backlight　with　color　temperature　of　5　560　K,6　500　K　and　10　000　K　as　a　reference.Accurate　and　efficient　mutual　conversion　between　the　spectrum　and　color　coordinate　can　be　achieved.These　results　simplify　the　form　of　spectral　function　and　numerical　computation,achieve　the　data　compression,and　provide　a　necessary　technical　basis　and　theoretical　guidance　for　white-balance　experiment　of　quantum-dot　backlight　source.
