Qhov sib txawv ntawm TV backlight vaj huam sib luag thiab LCD vaj huam sib luag

Lub teeb hluav taws xob sab hauv lub teeb hluav taws xob tseem hu ua lub rooj tsav xwm siab, thiab cov khoom siv hluav taws xob siv hluav taws xob --- lub rooj tsav xwm hauv sab hauv cov kua siv hluav taws xob yog hu ua kua siv hluav taws xob. Cov backlight pawg thawj coj saib yog pawg uas teeb lub LCD backlight!

Cov backlight tau siv los taws lub vijtsam. Yog nws tawg lawm, lub vijtsam yuav tsis cig. Yog tias koj siv lub teeb nyem kom ci ntawm lub vijtsam, koj tseem tuaj yeem pom ntawm daim duab. Cov. Cov. Lub vaj huam sib luag hauv LCD suav nrog txhua lub rooj sib txig hauv sab hauv LCD, uas yog, lub rooj tsav xwm fais fab, lub rooj tsav xwm loj, lub rooj tsav tsheb siab, lub rooj tsav tsheb tsav, thiab lub rooj tsav xwm me me, pawg thawj coj txais (rau cov chaw taws teeb tswj), thiab plug-in U disk, video, thiab audio Signal thiab li ntawd,

Lub teeb vaj huam sib luag tsuas tuaj yeem tso tawm lub teeb pom kev dawb, thiab cov teeb vaj huam sib luag ua haujlwm nrog cov kua siv lead ua vaj huam sib luag vim tias cov vaj huam sib luag ua kua tsis tuaj yeem ua rau pom kev. Cov backlight tsuas yog hloov qhov ci, tsis yog xim. Lub vaj huam sib luag ua kua hluav taws xob tuaj yeem cuam tshuam thiab lim lub teeb. Lub teeb dawb twb muaj tag nrho cov xim. Lub khob ua kua siv ua kua hluav taws xob tuaj yeem cais cov xim uas yuav tsum tau ua kom pom qhov pom ntawm lub teeb pom kev dawb ntawm lub teeb nrig rov qab, thiab teeb tsa cov duab tom qab tau teeb tsa. Tsis muaj qhov teeb pom kev rov qab, LCD vaj huam sib luag tseem tuaj yeem tso duab, tab sis nws zoo nkaus li txawv txawv, zoo li hnav cov hnub ci tsaus tshaj hauv ntiaj teb kom pom yam.

Tsis muaj lub LCD vaj huam sib luag, lub teeb vaj huam sib luag tsuas yog siv los ua lub teeb fluorescent.

LCD kov tshuaj ntsuam lub xov tooj txawb feem ntau pom hauv khw hnub no, tab sis thaum lub vijtsam tawg, lub vijtsam kov yuav tsum tau cais los ntawm LCD cais. Cov ntxaij vab tshaus xov tooj ntawm tes tam sim no muaj ntau haiv neeg thiab cov ua rau pom txawv dua, tab sis hauv kev tshuaj ntsuam xyuas zaum kawg, lawv cov ntaub ntawv tshuaj ntsuam tsis muaj dab tsi tshaj li LCD-OLED-saum toj no Yog li dab tsi yog qhov txawv ntawm ob cov ntaub ntawv no? Lub vijtsam twg zoo dua?

Tus LCD cais qhia koj tias qhov sib txawv tshaj plaws ntawm LCD thiab OLED yog tias OLED yog qhov teeb pom kev zoo rau tus kheej, thaum LCD yuav tsum tau taws teeb los ntawm lub teeb rov qab los ua zaub. Yog li cov khoom siv twg zoo dua?

Nyob rau tam sim no, feem ntau ntseeg tau tias cov thev naus laus zis ntawm OLED yog cov kev paub ntau dua thiab nws kuj yog qhov kev coj ntawm kev txhim kho yav tom ntej. Txawm li cas los xij, txoj kev txhim kho tam sim no tsis tau paub tab heev, feem ntau yog los ntawm AMOLED series cov ntxaij vab tshaus tsim los ntawm Samsung. Raws li lub zog loj hauv LCD camp, TFT muaj kev nkag siab ntau. Coob tus neeg xav tias TFT thev naus laus zis yog rov qab thiab qub dua. Txawm li cas los xij, qhov no tsis yog qhov xwm txheej. Tam sim no, yuav luag txhua lub xov tooj ntawm tes ua lag luam tseem siv TFT cov ntxaij vab tshaus, tab sis lawv siv cov thev naus laus zis sib txawv ntawm cov thev naus laus zis. IPS screen siv nyob rau hauv lub xov tooj nrov tshaj plaws Apple iPhone 4S yog hu ua qhov screen zoo tshaj. Qhov tseeb, IPS cov ntxaij vab tshaus kuj yog hom TFT cov ntxaij vab tshaus.

Txhawm rau kom nkag siab ntxiv qhov sib txawv ntawm ob hom ntawm cov ntxaij vab tshaus, peb yuav qhia qhov ua haujlwm ua haujlwm thiab tus yam ntxwv ntawm ob hom ntawm cov ntxaij. Kev txhais ntawm cov txheej txheem ua haujlwm LCD (luv luv rau Crystal Crystal Display), uas yog, cov khoom siv ua kua siv lead ua kua, yog cov zaub uas siv cov kua siv lead ua kua tswj lub teeb transmittance technology kom ua tiav xim.

Los ntawm qhov kev pom ntawm tus qauv ntawm cov kua siv lead ua cov zaub, LCD yog tsim ntawm ob lub iav sib tw nrog cov tuab li ntawm 1 hli, cais los ntawm kev sib txawv ntawm 5 μm uas muaj cov khoom siv siv lead ua kua. Vim tias cov khoom siv ua kua siv ua kua nws tus kheej tsis tawm lub teeb, muaj cov teeb ua lub teeb ci rau ntawm ob sab ntawm cov zaub tso saib, thiab muaj cov phaj backlight (lossis txawm tias lub teeb ci) thiab cov zaj duab xis nyob sab nraum qab ntawm cov kua siv lead ua kua zaub. Backlight phaj yog tsim ntawm cov khoom siv fluorescent. Nws tuaj yeem tawm teeb, nws txoj haujlwm tseem ceeb yog los muab cov teeb pom kev zoo ntawm keeb kwm yav dhau los.

Peb hom, CCFL tub yog txias cathode tubes, EEFL tub tsis muaj txias cathode, LED lub teeb hluav taws xob diodes, CCFL thiab EEFL, qhov sib txawv hauv luminescence: CCFL electrodes yog sab hauv lub raj, EEFL electrodes yog sab nraum lub raj, thiab EEFL tub ntxhais lub teeb ci ntawm CCFL yog ntau dua 60% siab dua li ntawm CCFL.

Qhov sib txawv ntawm kev tsav tsheb ntawm EEFL thiab CCFL: CCFL tuaj yeem tsuas yog tsav ntawm ib lub teeb, vim tias qhov voltage thiab cov yam ntxwv ntawm txhua lub teeb tau sib txawv, tsav txhua lub teeb uas muaj tib lub teeb ntwm ua rau lub teeb tawm yuav ua rau tag nrho lub ci ntsa iab ntawm LCD npo kom tsis sib npaug. EEFL tuaj yeem tsav mus tib seem, yog li xyuam xim thaum hloov lub teeb.

Qhov sib txawv ntawm cov ntawv sib txig sib luag ntawm EEFL thiab CCFL: CCFL xav tau ntau lub tshuab hluav taws xob kom tsav ntau lub teeb, uas yog, ib qho hloov pauv coj ib lub teeb, thaum EEFL tsuas xav tau ib qho hloov pauv lossis qhov hloov thib ob ntawm ob lub tshuab hluav taws xob kom tsav thiab taws txhua lub teeb hluav taws xob. Nyob rau hauv txoj kev no, los ntawm cov tsos ntawm cov hwj huam inverter, peb tuaj yeem txheeb xyuas seb lub teeb hom LCD TV yog dab tsi.

Muaj ntau ob peb LED backlight TVs, Hisense thiab Samsung's muaj cov qauv sib txawv
