Qhov txawv ntawm LED thiab LCD npo

Aug 12, 2017

Raws li ib lub tshuab ntaus LCD, lub cim tshiab tom qab no muaj ntau yam zoo, xws li kev ci ntsa iab, cov xim zoo nkauj, cov lus teb ceev, kev hloov ywj pheej, thiab tsis muaj teeb meem tshuaj xws li mercury. Tab sis nyob rau hauv ib txoj kev qhia ntawv, LCD LCD vaj huam sib luag, uas siv cov roj teeb ci ntsa iab, muaj qhov loj tshaj piv rau LCD, uas siv cov CCFL (txias cathode fluorescent teeb) ua lub teeb pom kev, feem ntau nyob rau hauv peb lub taw tes.


1. Lub thickness ntawm cov kua siv lead ua kua yuav txo tau ntxiv los ntawm kev siv cov kev lag luam ntawm LED

LED backlight yog ua los ntawm ntau daim phiaj xws li semiconductors, txhua tus nrog ib tus qauv hluav taws xob hauv LED, yog li ntawm LED backlight ntse realizes lub planarization ntawm lub teeb qhov chaw. Lub teeb ci qhov tsis zoo xwb tsis muaj teeb ci ci zoo nkaus li zoo, tab sis tsis tas yuav tsim kho qhov tsim tsim nyuaj, kom lub thickness ntawm LCD yuav thinner, thiab nws tseem muaj ntau dua kev ntseeg tau thiab stability. Thinner LCD panels txhais tau hais tias laptops tau sib zog lub cev qhov hnyav thiab zoo zog. Piv txwv li, VAIO TX phau sau ntawv, launched ntawm SONY, siv lub teeb ci rov qab LCD nrog lub thickness ntawm 4.5 hli xwb. LED npo phau ntawv vaj huam sib luag ntawm txog CCFL npo tib yam ntawm npuaj tuab ntawm 1/2.


2. Lub neej muaj zog, txo hwj chim ntau dua, thiab ntau qhov chaw tiv thaiv

Cov ntaub ntawv qhia tau hais tias lub npo LCD ib leeg siv li ntawm 30% ntawm lub tshuab computer lub zog siv, thiab kev siv cov teeb pom kev zoo ntawm LED, koj tuaj yeem txo qhov kev siv zog. Nws txuag fais fab tuag los ntawm 48% piv rau CCFL LCD screen feem ntau siv. Tsis tas li ntawd, LED tsis siv qhov teeb meem zoo li thaj tsam mercury, uas yog tus phooj ywg zoo heev, thaum Mercury hauv CCFL yog. LED yog heev phooj ywg zoo. LED kuj muaj ib qho loj zoo, uas yog, kev pab lub neej ntawm 100 txhiab teev, txawm tias siv tas li 10 teev hauv ib hnub, koj tuaj yeem mus ntxiv rau 27 xyoos. Nrog rau lub lag luam ntawm SONY tus TX Series ua piv txwv, piv nrog CCFT LCD thiab VAIO T series, lub thickness tau raug txo los ntawm 9mm mus rau 4.5 hli, qhov nyhav yog txo los ntawm 26% thiab ntev roj teeb lub neej rau ib teev, ntau dua li ntawm ob npaug qhov kev ntsuam xyuas cov ntaub ntawv muaj peev xwm. Vim tias cov teeb ciav hlau teeb ntawm lub cev yuav tsum tau nce mus rau 530V, lub teeb ua haujlwm tau zoo, thiab siv cov tshuab LED los soj ntsuam, tsuav yog qhov teeb meem ntawm 40V yuav ua haujlwm kom zoo, kom lub hwj chim ua kom zoo dua siv, kom ua tiav ntev roj teeb lub neej 9 teev.


3.LED backlight screen xim kev ua haujlwm zoo dua li CCFL

Lub siab dua tus nqi tshiab kom LED muaj kev ua tau zoo dua nyob rau hauv kev yees duab, ib qho yooj yim rau cov tub ntxhais teb saib cov lus teb yog 1000 zaus LCD npo, nyob rau hauv lub teeb ci tuaj yeem saib zoo tom qab, thiab hloov mus rau 40 degree centigrade. Ntawm qhov tod tes, vim tus thawj CCFL backlight xim purity, tsis zoo hauv cov xim. Qhov no ua LCD yuav tsis zoo rau CRT hauv grayscale thiab xim hloov. Raws li txoj kev kuaj pom, CCFL backlight tau tsuas yog ua tau 78% ntawm NTSC xim thaj tsam, thaum lub LED backlight tau yooj yim tau ntau tshaj 100% ntawm NTSC xim cheeb tsam. Hauv kev xim thiab xim hloov, LED backlight kuj muaj kev pom zoo.
