LCD npo thev naus laus zis yog qhov yooj yim heev: cov duab LCD yog tsim los ntawm cov khoom uas nyob mus ib txhis hauv cov kua hauv lub xeev, tab sis muaj qee cov yam ntxwv ntawm cov muaju.
LCD zaub yog ib qho khoom siv passive, uas txhais tau hais tias nws tsis tsim lub teeb los tso saib cov cim, duab, yeeb yaj kiab, thiab cov animations. Tab sis nws tsuas hloov lub teeb hla nws. Cov qauv sab hauv ntawm LCD piav qhia tias lub teeb hloov pauv li cas thaum hla nws los tsim cov cim, duab, thiab lwm yam.
LCD npo technology
Ib qho screen LCD yog ib pawg me me hu ua pixels uas tuaj yeem hloov kho kom pom cov ntaub ntawv. Cov zaub no muaj ob peb txheej, ntawm ob lub vaj huam sib luag (hu ua substrates) ua los ntawm cov khoom siv iav dawb sodium ua lub luag haujlwm tseem ceeb. Muaj ib txheej nyias ntawm cov kua siv lead ua kua nruab nrab ntawm cov substrates. Muaj grooves ntawm lub vaj huam sib luag uas coj cov crystals, muab lawv ib qho kev taw qhia tshwj xeeb. Cov grooves ntawm txhua lub vaj huam sib luag yog sib npaug, tab sis lawv yog perpendicular rau ib leeg. Longitudinal grooves tau txais los ntawm kev tso cov yeeb yaj kiab pob tshab rau ntawm cov iav thiab tom qab ntawd ua nws hauv ib txoj kev tshwj xeeb. Thaum nyob rau hauv kev sib cuag nrog cov zawj, kev taw qhia ntawm molecules nyob rau hauv tag nrho cov hlwb yog tib yam. Lub LCD vaj huam sib luag yog illuminated los ntawm lub teeb ci, nyob ntawm nws txoj hauj lwm, raws li lub LCD vaj huam sib luag ua hauj lwm los ntawm kev xav los yog lub teeb kis tau tus mob.Thaum ib lub vaj huam sib luag hla, lub dav hlau polarization ntawm lub teeb beam tig 90 degrees. Thaum ib qho hluav taws xob tshwm sim, cov khoom molecular ua raws li lub teb hluav taws xob, thiab lub kaum sab xis ntawm lub teeb polarization sib txawv ntawm 90 degree. Los ntawm kev siv tshuab LCD saib tshuab los tsim cov ntxaij vab tshaus, lub teeb nraub qaum ntawm lub monitor yog siv los tso tawm cov duab xim, yog li tsim lub teeb rau sab nraum qab ntawm LCD saib. Nws yog ib qho tsim nyog kom tau txais cov duab zoo, txawm tias lawv tsaus heev. Xim yog tau los ntawm peb cov ntxaij lim dej uas paub qhov txawv ntawm peb lub ntsiab ntawm cov hluav taws xob ntawm lub teeb dawb. Los ntawm kev sib txuas peb lub ntsiab xim rau txhua pixel ntawm qhov screen, koj tuaj yeem tsim cov xim.
Kev sib piv technology: yav dhau los thiab tam sim no.
Niaj hnub nimno LCD cov ntxaij vab tshaus tseem hu ua flat panels, dual scan active matrices, thiab nyias zaj duab xis transistors. Tam sim no lawv nrov heev - txhua tus nyiam lawv cov tsos zoo nkauj, hnav, compact, thiab ua haujlwm zoo. Cov duab LCD muab qhov zoo sib xws thiab cov duab ci thiab meej. Yav dhau los, LCD thev naus laus zis tau tsim qeeb, nrog kev ua haujlwm qis dua thiab qis dua piv rau tam sim no. Thawj cov txheej txheem matrix, hu ua passive matrix, ua tau zoo hauv cov ntaub ntawv cov ntaub ntawv, tab sis nrog kev hloov pauv sai ntawm cov duab, thiaj li hu ua "ghosts" tshwm rau ntawm qhov screen. Vim tias qhov chaw sib cais ntawm txhua pixel los ntawm LCD thev naus laus zis, qhov pom tseeb ntawm cov ntawv tau txais yog siab dua piv rau CRT cov lus, uas yav dhau los tuaj yeem sib tw nrog LCD zaub.
Tau kawg, nrog rau kev txhim kho thev naus laus zis thiab xav txog tag nrho cov txheej txheem ntws, LCD cov lus tau ntev tau ua tus thawj coj thiab tuav txoj haujlwm tseem ceeb hauv ntau yam kev siv ntawm cov lus. LCD raws li cov lus qhia tsis yog tsuas yog siv dav hauv desktop computers, tab sis kuj muaj ntau yam khoom siv hluav taws xob xws li TV, duab thiab koob yees duab, laptops, ntsiav tshuaj, smartphones, tsheb navigators, e-phau ntawv, MP3 thiab lwm yam players, watches, thiab lwm yam.
