Kev Ntsuam Xyuas ntawm LCD Zaub Kev Lag Luam Fundamentals
Tso lus
Liquid Crystal Display (LCD) technology stands as the most widely sawed flat-panel imaging solution hnub no. Kev siv cov txheej txheem tsim khoom lag luam, kev ua haujlwm ruaj khov, thiab cov nqi tswj tau, nws tau nkag mus rau ntau hom kev lag luam -xws li cov neeg siv khoom siv hluav taws xob, kev lag luam automation, thiab cov tshuab automotive- tawm los ua qhov tseem ceeb pom kev cuam tshuam rau cov khoom siv hluav taws xob niaj hnub no. Nws txoj haujlwm ua haujlwm yog nyob ntawm electro- kho qhov muag khoom ntawm cov kua siv lead ua kua molecules; los ntawm kev siv hluav taws xob teb los hloov kho molecular alignment, thev naus laus zis hloov lub teeb kis tau zoo. Cov txheej txheem no, ua ke nrog cov xim lim kom ua cov duab, ua kom pom cov zis tawm. Raws li LCDs lawv tus kheej tsis tawm lub teeb, lawv xav tau ib lub teeb pom kev zoo los muab lub teeb pom kev zoo.
Hauv kev lag luam, ntau lub vaj huam sib luag thev naus laus zis tau hloov kho kom haum rau cov ntawv thov sib txawv, txawv los ntawm lawv cov kev npaj tshwj xeeb thiab cov duab kos duab. Thaum ntxov-theem, nkag- theem kev daws teeb meem tso siab rau qhov yooj yim twisted-nematic molecular qauv; Cov yam ntxwv los ntawm tus nqi qis thiab lub sijhawm teb sai, cov no tau siv feem ntau hauv cov khoom siv yooj yim. Dav - saib - kaum kev daws teeb meem - txawv ntawm qhov sib npaug ntawm cov xim luam tawm thiab pom cov kaum sab xis mus txog 180 degrees- tau dhau los ua qhov kev xaiv tseem ceeb rau cov khoom siv hauv chaw ua haujlwm, chaw ua haujlwm tsim, thiab cov khoom siv lom zem. Siab-kev sib piv kev daws teeb meem, sib piv, ua tau zoo hauv qhov tsaus ntuj- qhov kev ua tau zoo ntawm qhov xwm txheej- ua kom tob dua, cov xim dub zoo dua- thiab nquag siv rau hauv cov khoom siv suab paj nruag thiab cov duab nkhaus kom txaus siab rau qhov kev xav tau ntawm ntau tus neeg siv.
Hloov kho dua tshiab rau lub teeb pom kev rov qab ua lub luag haujlwm tseem ceeb rau kev txhim kho cov duab zoo. Cov khoom siv teeb pom kev zoo li qub tau maj mam hloov los ntawm lub zog -kev ua tau zoo, lub teeb yuag LED daws teeb meem. Cov tshuab LED no tau muab faib ua ob hom raws li lub teeb pom kev zoo: ncaj qha -lit thiab ntug-lit. Tus qub muab kev tswj lub teeb kom meej dua, thaum lub tom kawg ua kom yooj yim rau kev tsim cov khoom siv thinner, sib dua. Nyob rau hauv xyoo tas los no, Micro-LED backlight technology tau nce nrawm nrawm; los ntawm kev siv siab- qhov ntom ntom ntawm cov me me LEDs los pab kom dimming hauv zos, nws ua kom cov duab zoo sib xws thiab qhov ci ci. Thaum ua ke nrog Quantum Dot cov ntaub ntawv, cov xim gamut tau nthuav dav ntxiv, yog li ua kom muaj kev txhim kho ntau yam hauv cov duab zoo ntawm cov khoom siv siab{10}} kawg.
Lub peev xwm ntawm qhov kev siv thev naus laus zis no txuas ntxiv nthuav dav, tau ntev txij li dhau los ntawm cov ciam teb ntawm cov khoom siv hluav taws xob ib txwm muaj. Hauv cov neeg siv khoom lag luam, nws suav nrog ntau yam khoom lag luam, suav nrog TV, khoos phis tawj khoos phis tawj, thiab cov khoom siv nqa tau yooj yim. Hauv kev lag luam tsheb, cov tshuab ua haujlwm ntse- ncua kev tswj hwm hauv nruab nrab, pawg ntsuas, thiab sab nraub qaum- rooj zaum kev lom zem tso saib - nce ntxiv siv cov khoom siv LCD uas tau tsim kho rau siab - qhov kub thiab txias thiab kev ntseeg tau tshwj xeeb. Kev tswj hwm kev lag luam thiab cov cuab yeej kuaj mob kho mob vam khom siab -kev daws teeb meem, qis- ua yuam kev cov vaj huam sib luag los xyuas kom meej kev ua haujlwm. Tsis tas li ntawd, cov xwm txheej ntawm daim ntawv thov tshwm sim-xws li cov tshuab hauv tsev ntse, kos npe rau kev lag luam, thiab kev tshaj tawm kev lag luam- tau txais kev hloov kho, loj - hom ntawv, thiab cov khoom lag luam zoo li tsis tu ncua.
Nyob rau hauv lub ntiaj teb no kev lag luam toj roob hauv pes, domestic tuam txhab uas muag tau ruaj ib tug tseem ceeb txoj hauj lwm. Los ntawm kev tsim kho qib siab - tiam ntau lawm kab mus rau kev tshawb fawb thiab kev loj hlob ntawm cov khoom tseem ceeb, cov tuam txhab no tau nce qib ua tiav tus kheej- kev txaus siab thoob plaws tag nrho cov saw hlau, yog li tsav tag nrho cov nqi optimization thiab thev naus laus zis tshiab. Txawm hais tias kev tawm tswv yim rau tus kheej -emissive technologies yog tsim kom muaj kev sib tw toj roob hauv pes me me - hom, siab -kawg sector, cov kev daws teeb meem uas twb muaj lawm tseem ua tus thawj coj hauv nruab nrab- mus rau- cov khoom lag luam loj, siv lawv cov txiaj ntsig hauv tus nqi- kev ua tau zoo thiab thev naus laus zis.
Tsiv mus tom ntej, kev lag luam tau npaj los hloov mus rau qhov kev daws teeb meem siab dua, kev siv hluav taws xob qis dua, thiab hloov kho tau yooj yim. Tsav los ntawm kev hloov kho cov kev xav tau ntawm kev loj hlob sectors-xws li cov khoom siv tsheb, kev tswj hwm kev lag luam, thiab kev lag luam kev lag luam -kev lag luam yuav txuas ntxiv txhim kho cov neeg siv kev paub dhau los ntawm kev siv thev naus laus zis txuas ntxiv. Nyob nruab nrab ntawm qhov sib txawv ntawm kev sib txawv hauv kev lag luam zaub, cov thev naus laus zis no tau teeb tsa kom muaj kev lag luam tseem ceeb nyob rau lub sijhawm ntev, muab kev ruaj ntseg thiab muaj txiaj ntsig pom kev txhawb nqa rau ntau qhov sib txawv ntawm cov ntse davhlau ya nyob twg los ntawm nws qhov kev hloov pauv tsis tu ncua.
