Cov yeeb yam zoo: Nws yog xim dawb (LCD npo xim) nrog cov nab npawb dub thiab cov ntawv sau rau hauv qab. Nws tseem yog keeb kwm yav tsaus nti uas muaj keeb kwm yav tsaus ntuj. Qhov sib txawv ntawm qhov sib piv tseem ceeb. Nws zoo nkaus li meej hauv cov neeg mob.
Tsis zoo saib: yog dub qab, cov zauv thiab cov tsiaj ntawv yog cov dawb (LCD npo xim) zaub, uas yog, tom qab dub tsaus nti cov cim, feem ntau yuav tau ntxiv qhov teeb meem kom pom tseeb, ua lub hnub thiab sab nraum zoov zoo, ntau dua siv e-phau software. Yuav phim cov xim saib, qhov muag pom muaj kev zoo, tsis yoojyim rau kev xav, zoo nkaum.
Nyob rau hauv kev nkag siab yooj yim, LCD LCD ntxaij yuav hu ua cov ntxaij vab tshaus LCD. Cov ntxaij vab tshaus LED tsis muaj cov khoom siv lead ua kua, vim li ntawd lawv tsis tuaj yeem hu ua LED cov ntxaij lim dej. Lawv tsuas yog hu ua LED ntxig.
Paub yooj yim LCD
Cov kua siv lead ua kua yog ib qho kev pom zoo, nws tsis tuaj yeem tawm lub teeb, tsuas yog siv lub teeb nruab nrig. Nws qhia tau hais tias tsuas yog ib qho me me ntawm lub zog rau cov qauv lossis cov cim. Vim tias cov kev siv zog tsawg tsawg thiab kev siv lub tshuab, LCDs tau dhau los ua ib qho qauv zoo dua.
Cov khoom siv lead ua kua siv hauv cov kua siv lead ua kua yog ib qho khoom siv uas muaj cov kua thiab cov khoom sib xyaws. Nws tus qauv txhuam tus qauv yog feem ntau ua nyob rau hauv lub hauv qab ntawm cov kua qaub cell, tab sis nws muaj peev xwm hloov nws cov kev taw qhia nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob.
Rau qhov zoo TN-LCD, thaum tsis muaj qhov hluav taws xob siv rau qhov electrode, LCD yog nyob rau hauv lub xeev "OFF" thiab lub teeb lub zog kis tau los ntawm LCD mus rau lub xeev dawb; Thaum ib qho kev siv hluav taws xob nyob rau lub electrode, LCD tseem nyob rau hauv "ON" lub xeev, qhov ntev ntawm txoj kab ntawm cov kua siv lead ua kua Cov khoom siv hluav taws xob, Lub teeb tsis dhau ntawm LCD thiab tshwm dub. Xaiv qhov kev siv qhov taw hluav taws xob thoob plaws cov electrodes, ntau cov qauv yuav raug xa tawm.
Rau qhov STN-LCD, lub kaum sab xis ntawm cov kua siv lead ua kua yog qhov loj, yog li qhov sib txawv zoo dua thiab qhov pom lub kaum sab xis yog qhov dav. STN-LCD yog raws li lub hauv paus ntsiab lus ntawm lub tsho, nws cov xim yooj yim yog feem ntau daj-ntsuab, xim xiav, daj ntsuab
pwm. Thaum siv lub pob zeb liab qab zib, lub hauv paus xim hloov xim txhawm rau ua ib lub pwm. Thaum siv lub tshuab zaj duab xis nrog cov thev naus laus zis, lub hauv paus xim yuav pib dawb. Nyob rau lub sij hawm no, STN ua ib hom xim dub thiab dawb, uas yog, FSTN. Polarization ntawm cov saum toj no peb hom siv.
Thaum cov yeeb yaj duab lem 90 °, nws yog ib tus qauv xiav thiab cov nyhuv yuav zoo dua.
Lub LCD muaj peb cov hom zaub: paab, puv transitive, thiab hloov txav. Ib daim ntawv phaj yog txuas tom qab qab polarizer ntawm tus lej LCD. Feem ntau yog siv sab nraum zoov thiab hauv cov chaw ua haujlwm zoo. Lub qab rooj polarizer ntawm lub teeb hloov pauv hauv lub cev yog lub yeeb yaj kiab uas hloov pauv, uas yuav tsum tau siv lub nrig, thiab feem ntau yog siv nyob rau thaj chaw tsis zoo. Tus semi-transparent LCD yog nruab nrab ntawm cov saum toj no ob. Hauv qab ncov qaumteb qab zib muaj peev xwm ua tau ib qho kev cuam tshuam, thiab feem ntau kuj muaj teeb pom kev rov qab. Thaum lub teeb zoo, qhov kev lag luam yuav tsum muab tua. Thaum lub teeb tsis ploj, qhov kev lag luam yuav siv los ua kom pom cov LCD. LCD cov duab tseem muab faib ua qhov zoo thiab tsis zoo. Cov zoo LCDs nthuav qhia cov tsiaj ntawv dub rau tom qab dawb thiab zoo tshaj plaws nyob rau hauv qhov kev ntsuas thiab txav teeb ci; tsis zoo LCDs tau qhia nyob rau hauv cov xim dawb, thiab feem ntau yog siv rau tag nrho-thickness LCDs. Nrog lub tsom teeb, cov ntawv sau tau meej meej thiab yooj yim nyeem.
Cov yeeb yaj duab zoo (xim dub dawb) POSITIVE HOM
Tsis zoo saib hom (dawb ntawm dub) HOM NEEG HOM
