Liquid Crystal Display (LCD) yog ib qho tseem ceeb ntawm lub xov tooj ntawm tes uas ua lub luag haujlwm tseem ceeb hauv kev nthuav tawm cov duab thiab cov ntawv.Nws yog thev naus laus zis tom qab lub vijtsam uas tso cai rau cov neeg siv cuam tshuam nrog lawv cov cuab yeej pom.
Cov ntxaij vab tshaus LCD feem ntau yog siv hauv cov xov tooj ntawm tes vim lawv qhov pom tseeb zoo, kev tsim cov xim, thiab lub zog ua haujlwm.Cov ntxaij vab tshaus no yog tsim los ntawm ntau cov khaubncaws sab nraud povtseg, suav nrog lub teeb nraub qaum, xim lim, kua siv lead ua kua molecules, thiab pob tshab electrode daim phiaj.
Lub luag haujlwm tseem ceeb ntawm lubLCDyog tswj kev tsim cov duab.Thaum cov khoom siv hluav taws xob raug siv rau cov zaub, cov kua siv lead ua kua molecules nyob rau hauv lub vijtsam sib haum kom tso cai lossis thaiv qhov kev pom ntawm lub teeb.Cov txheej txheem no txiav txim siab qhov pom ntawm cov pixels sib txawv, thaum kawg tsim cov duab peb pom.
Cov ntxaij vab tshaus LCD siv hauv cov xov tooj ntawm tes tuaj ntau hom, xws li TN (Twisted Nematic) thiab IPS (In-Plane Switching) cov lus qhia.TN cov lus pom feem ntau pom hauv cov xov tooj siv nyiaj txiag, muab lub sijhawm teb zoo thiab tus nqi pheej yig.Ntawm qhov tod tes, IPS cov lus qhia muaj cov xim zoo dua, qhov pom dav dua, thiab kev ua tau zoo tag nrho, ua rau lawv xaiv qhov kev xaiv zoo tshaj plaws rau cov smartphones siab.
LCD cov ntxaij vab tshaus tseem muab ntau yam zoo dua lwm hom kev yees duab.Ib qho ntawm qhov zoo tshaj plaws yog lawv lub zog ua haujlwm.LCDs siv hluav taws xob tsawg dua piv rau cov khoom siv thev naus laus zis xws li CRT (Cathode Ray Tube) cov lus qhia.Qhov kev ua tau zoo ntawm lub zog no ua kom lub roj teeb lub neej ntev dua rau cov xov tooj ntawm tes, tso cai rau cov neeg siv txuas nrog rau lub sijhawm ntev yam tsis muaj kev txhawj xeeb txog kev siv hluav taws xob.
Ntxiv thiab,LCD cov ntxaij vab tshausmuab visibility zoo heev txawm nyob rau hauv qhov chaw ci ntsa iab.Lub backlighting feature ntawm LCD qhia illuminates lub vijtsam, ua rau cov neeg siv pom cov ntsiab lus kom meej txawm nyob rau hauv lub hnub ncaj qha.Qhov no ua rau cov ntxaij vab tshaus LCD tsim nyog rau kev siv sab nraum zoov, txhim kho cov neeg siv kev paub.
Tsis tas li ntawd, LCD thev naus laus zis tso cai rau kev tsim cov ntxaij vab tshaus nyias thiab lub teeb, ua rau cov xov tooj ntawm tes sleek thiab portable.Cov khoom siv slim thiab compact no haum yooj yim hauv hnab ris thiab hnab, ua kom yooj yim rau cov neeg siv thaum mus.
Raws li kev siv thev naus laus zis, LCD cov ntxaij vab tshaus txuas ntxiv txhim kho nyob rau hauv cov nqe lus ntawm kev daws teeb meem, xim raug, thiab ci ntsa iab.Kev tshawb fawb tsis tu ncua thiab kev tsim kho lub hom phiaj txhawm rau txhim kho qhov pom kev paub thiab muab cov neeg siv khoom zoo tshaj plaws hauv lawv lub xov tooj ntawm tes.
Hauv kev xaus, LCD ntawm lub xov tooj ntawm tes yog lub vijtsam thev naus laus zis lub luag haujlwm rau kev pom cov duab thiab cov ntawv.Nws muab kev pom tseeb, xim luam tawm, lub zog ua haujlwm, thiab pom kev zoo txawm tias nyob hauv qhov chaw ci ntsa iab.Nrog kev nce qib tsis tu ncua, cov ntxaij vab tshaus LCD pab txhawb rau kev tsim qauv zoo nkauj thiab nqa tau yooj yim ntawm cov xov tooj ntawm tes niaj hnub, muab cov neeg siv kev paub zoo dua.
