LED yog lub npe luv ntawm cov lus Askiv lub npe ntawm Lub Teeb-Emitting Diode, uas feem ntau hnov ntawm lub teeb-emitting diodes. Nws yog ib qho khoom siv hluav taws xob semiconductor uas tuaj yeem tawm lub teeb los ntawm trivalent thiab pentavalent ntsiab. LED zaub peb tab tom tham txog yog hais txog cov zaub nrog lub teeb-emitting ntsiab ua los ntawm LEDs (lub teeb-emitting diodes) raws li lub backlight.
Lub npe tag nrho ntawm LCD yog Liquid Crystal Display. Liquid Crystal Display yog txhais ua kua siv lead ua kua. Lub npe tag nrho ntawm LCD yog kua siv lead ua zaub hauv Suav. Nws yog lub vaj huam sib luag vaj huam sib luag uas muaj ntau yam xim dub thiab dawb lossis xim pixels, uas yog siv dav hauv ntau yam khoom siv digital.
Qhov sib txawv tseem ceeb ntawm LCD thiab LED yog raws li hauv qab no:
1. Zoo sib xws
LED LCD npo tuaj yeem hloov lub teeb siv ceev heev, yog li lub teeb ci ntsa iab tuaj yeem hloov kho hauv zos raws li qhov xav tau ntawm cov duab hauv zos, yog li cov duab tsaus tuaj yeem tsaus dua, thiab qhov sib piv zoo sib xws tuaj yeem siab dua li ntawm lub LCD npo. Tshwj xeeb tshaj yog rau cov teeb pom kev ncaj qha LED backlights, kev txhim kho hauv qhov sib txawv zoo sib xws yog pom tseeb dua.
2 loj
Kev siv LED LCD npo backlight tuaj yeem txo qhov tuab, ntim thiab qhov hnyav ntawm lub TV, thiab ntug LED LCD npo (ntug LED) tuaj yeem ncav cuag tsawg dua 1cm.
3. Kev siv hluav taws xob
LED LCD npo backlight nws tus kheej txuag lub zog piv rau LCD cov ntxaij vab tshaus hauv qis thiab nruab nrab luminosity. Ua ke nrog lub zog dimming ntawm LED LCD npo raws li cov duab txiav, LED LCD npo backlight tuaj yeem txuag tau li 20% -50% ntawm lub zog noj.
4. Xim gamut
Qhov ncaj-lit LED LCD npo backlight nrog ywj siab peb-thawj xim LCD npo muaj qhov dav xim gamut dua li LCD LCD cov ntxaij vab tshaus.
5. Lub neej
Lub neej ntev ntawm LED LCD npo backlight yog ntev dua li ntawm LCD LCD npo.
6. Kev tiv thaiv ib puag ncig
LED LCD npo backlight yog ib puag ncig zoo dua li LCD LCD npo. LED LCD npo backlight yog sib dua thiab siv roj tsawg thaum thauj. LED LCD cov ntxaij vab tshaus yog ib puag ncig zoo dua li cov ntxaij vab tshaus LCD thaum lawv muab pov tseg, vim tias cov ntxaij vab tshaus LCD muaj cov kab mercury. Lub neej ntev dua kuj txo cov khoom pov tseg.
