LED cov neeg tsis tuaj yeem tso cov xim dub, feem ntau vim yog cov qauv thiab cov qauv tso tawm ntawm LED Backlight Technology. Ntawm no yog ob peb yam:
1. Backlight kis: LED qhia tawm ua haujlwm Backlight los taws lub lcd vaj huam sib luag. Txawm tias thaum cov zaub yog xim dub, lub backlight ua rau lub teeb, tab sis cov kua crystal txheej nres nws los ntawm kev hla dhau. Vim tias cov kua crystal tsis tuaj yeem thaiv txhua lub teeb, qee tus yuav tau txais los ntawm dub dub.
2. Ua kua Crystal Molecule kev npaj: LCD Panels tswj lub teeb ntws los ntawm kev rov ua kua crystal molecules molecules molecules molecules molecules molecules molecules molecules molecules molecules molecules molecules molecules molecules molecules molecules molecules molecules molecules molecules. Thaum uas qhia dub, cov kua ua kua crystal molecules yuav tsum muaj kev ncaj qha rau kev tiv thaiv lub teeb. Txawm li cas los xij, vim tias kev npaj ua kua lead ua kua crystal molecules tsis tag sib npaug, qee lub teeb yuav mus dhau, tsim cov zaub tsaus tsis tau.
3. Nrawm Backlight: LED Backlights tuaj yeem tsim cov teeb meem tsis sib xws nyob hauv ntau thaj tsam ntawm lub vijtsam, hu ua "Backlight los ntshav". Qhov tshwm sim no yog pom tshwj xeeb thaum xim dub yog qhia, ua rau halos ib ncig ntawm lub vijtsam lub ciam teb.
4. Piv txwv tsis sib xws: qhov sib piv yog lub peev xwm ntawm cov zaub kom pom cov xim ci thiab tsaus ntuj. Qhov sib piv ntawm LED cov neeg saib xyuas feem ntau yog txwv los ntawm qhov ci ci ntawm lub backlight. Txawm hais tias cov kua crystal txheej tuaj yeem thaiv lub teeb, qhov ci ntawm lub backlight yuav txwv kev ua tau zoo ntawm dub.

Olted qhia tau zoo dua ntawm cov xim dub txij li txhua lub pixel tuaj yeem tua cais kom muaj xim dub. OLED kev thev naus laus zis tsis muaj backlight, thiab txhua tus pixel tsim nws tus kheej lub teeb, yog li ntawd thaum pom cov xim dub, ua rau raug kaw dub, ua rau muaj cov xim dub zoo meej.
