LCD thiab LED kua siv lead ua kua bar qhia: Qhov twg muaj qhov kub hnyiab qis dua - nyob rau hauv qhov tshwm sim thiab lub neej ntev dua?

LCD thiab LED kua siv lead ua kua bar qhia: Qhov twg muaj qhov kub hnyiab qis dua - nyob rau hauv qhov tshwm sim thiab lub neej ntev dua?

Niaj hnub no lub caij nyoog ntawm kev hloov pauv sai sai ntawm cov cuab yeej siv digital, LCD (kua siv lead ua kua zaub) thiab LED (lub teeb-emitting diode zaub) yog ob lub ntsiab lus tseem ceeb uas siv dav hauv ntau yam khoom siv hluav taws xob. Rau cov neeg siv khoom, kev nkag siab qhov sib txawv ntawm qhov kub hnyiab- qhov tshwm sim thiab kev ua neej nyob ntawm ob hom khoom no yog qhov tseem ceeb rau kev txiav txim siab yuav khoom.

I. LCD kua siv lead ua bar zaub: qis hlawv- nyob rau hauv qhov tshwm sim, lub neej ntev dua

LCD kua siv lead ua bar qhia ua tiav cov duab los ntawm kev tswj cov kev sib raug zoo ntawm cov kua siv lead ua kua molecules. Vim nws txoj hauv kev ua haujlwm, LCD cov ntxaij vab tshaus tsis tshua muaj hluav taws kub hauv kev siv ib txwm. Hlawv- tshwm sim thaum cov ntsiab lus pixel nyob twj ywm hauv tib lub xeev ntev, ua rau cov pixels hauv qee qhov chaw kom muaj hnub nyoog thiab tsim cov duab seem. Txawm li cas los xij, cov ntxaij vab tshaus LCD tsis txhob ncua lub sijhawm ntev ntawm cov ntsiab lus pixel los ntawm kev hloov pauv hloov pauv ntawm cov kua siv lead ua kua molecules, txo qhov kev pheej hmoo ntawm hlawv -in.

Nyob rau hauv cov nqe lus ntawm lifespan, LCD kua siv lead ua bar qhia kuj ua tau zoo. Ua tsaug rau nws cov thev naus laus zis paub tab thiab kev ua haujlwm ruaj khov, cov ntxaij vab tshaus LCD feem ntau muaj lub neej ntev dua 50,000 teev, sib npaug rau kev siv tsis cuam tshuam rau ntau tshaj 5 xyoos. Tsis tas li ntawd, cov ntxaij vab tshaus LCD muaj cov qauv yooj yim thiab tus nqi qis dua, ua rau cov nqi kho qis dua.

II. LED kua siv lead ua bar zaub: Kuj tsis tshua muaj kub hnyiab -hauv, tab sis lifespan cuam tshuam los ntawm ntau yam

LED cov kua siv lead ua kua bar zaub siv cov cuab yeej teeb pom kev zoo, qhov twg LED teeb ci ntsa iab tag nrho lub vijtsam, thiab cov kua siv lead ua kua yog hloov kho kom ua tiav cov duab pom. Zoo ib yam li cov ntxaij vab tshaus LCD, cov ntxaij vab tshaus LED kuj tsis tshua muaj kev kub hnyiab - nyob rau hauv kev siv ib txwm. Qhov no yog vim hais tias cov ntxaij vab tshaus LED kuj tsis txhob ncua lub xeev cov ntsiab lus ntawm pixels los ntawm kev hloov pauv hloov pauv ntawm cov ntsiab lus pixel, txo qhov kev pheej hmoo ntawm hlawv -hauv.

Txawm li cas los xij, lub neej ntawm LED cov ntxaij vab tshaus tuaj yeem cuam tshuam los ntawm ntau yam. Txawm hais tias theoretically, LED cov ntxaij vab tshaus tuaj yeem muaj lub neej ntev tshaj 100,000 teev lossis txawm tias 10 xyoo, qhov tseeb lifespan nyob ntawm ntau yam, xws li cov chaw tsim khoom cov txheej txheem, ntim tshuab, hom ntawm LED chips siv, thiab zaus ntawm kev siv. Piv txwv li, LED cov ntxaij vab tshaus nrog GOB lossis COB ntim muaj qhov ua tau qis dua ntawm cov nti poob, ua rau muaj kev ruaj ntseg zoo dua thiab kev ua neej ntev dua. Lub caij no, LED cov ntxaij vab tshaus uas siv ntau zaus, xws li cov chaw ceev xwm ceev lossis cov ntaub ntawv xov xwm hauv pej xeem, yuav muaj lub neej luv dua li cov ntxaij vab tshaus uas qee zaus qhib.

III. Kev sib piv zoo: Xaiv cov kua siv lead ua kua zoo tshaj plaws

Zuag qhia tag nrho, ob qho tib si LCD thiab LED cov kua siv lead ua kua bar qhia tsis tshua muaj kev kub hnyiab- nyob rau hauv kev siv ib txwm. Nyob rau hauv cov nqe lus ntawm lifespan, ob leeg ua tau zoo, tab sis qhov tseeb lifespan yuav txawv nyob ntawm ntau yam. Yog li ntawd, thaum xaiv cov zaub, cov neeg siv khoom yuav tsum txiav txim siab raws li lawv cov kev xav tau tiag tiag thiab kev siv ib puag ncig.

Rau lub sijhawm uas xav tau ntev- lub sij hawm tso saib cov duab zoo li qub, xws li cov chav sib tham lossis cov chaw ua yeeb yam, LCD kua siv lead ua bar qhia yuav tsim nyog dua, vim lawv muaj qhov kub hnyiab qis dua - nyob rau hauv qhov kev pheej hmoo. Rau lub sijhawm uas xav tau qhov ci ntsa iab, qhov sib txawv siab, thiab qhov pom dav, xws li cov ntawv tshaj tawm sab nraum zoov lossis loj - qhov chaw ua yeeb yam, LED cov ntxaij vab tshaus yuav muaj qhov zoo dua.

Hauv cov ntsiab lus, thaum xaiv ntawm LCD lossis LED kua siv lead ua kua bar qhia, cov neeg siv khoom yuav tsum xav txog qhov kub hnyiab - nyob rau hauv qhov tshwm sim, lifespan, thiab cov kev siv tiag tiag los xaiv cov khoom tsim nyog rau lawv tus kheej.
