Cov kev paub me ntsis uas paub txog cov kua siv lead ua kua

Xim tshawb: 16.7 / 16.2 lab xim txawv
Nws tsis muaj qhov tsis lees paub tias tam sim no, LCD qhia ua CRT qhov successor yog cov qauv ntawm cov sij hawm, tab sis tam sim no CRT thiab LCD cov lus qhia yuav coexist rau ib lub sij hawm ntev, tab sis cov sib piv ntawm cov muag ntawm ob lub lag luam tau meej meej illustrated cov sib lub neej yav tom ntej. Tab sis ntau tus phooj ywg tab tom xav xaiv cov kua siv lead ua kua, qee qhov teeb meem tshiab tau raug. Lub LCD muaj kaum xyoo ntawm keeb kwm ntawm CRT, thiab ntau yam ntawm nws cov ntsiab lus kev paub tsis paub raws li CRT.
Thaum peb yuav siv cov kua siv lead ua kua, peb yuav tsum xyuam xim dab tsi thiab yuav ua li cas thiaj li xav txog cov kev ntsuas uas tau muab los ntawm lub khw muag khoom. Qhov no txaus rau qee tus phooj ywg kom mob taub hau. Txawm tias qee cov laus "cov noog" poob los ntawm kev dag ntxias cov tuam txhab. Tsab ntawv xov xwm no yog teeb meem ntawm cov teeb meem saum toj no, yog li koj muaj peev xwm nkag siab tob txog cov kua siv lead ua kua thiab tej yam kev tsis tseem ceeb.
Tag nrho cov ncauj lus xav kom muaj kev cuam tshuam 24 xuab moos / 16.7 M xim ntawm daim video card tso tawm, tab sis rau cov qauv siv tam sim no, peb yuav tsum paub qhov txawv ntawm cov xim 16.7M thiab 16.7M.
Ntawm daim ntawv, 24 xuab nrig xim yog tau los ntawm 256 hom liab thiab 256 ntsuab thiab 256 hom xiav. Qhov siab tshaj plaws ntawm cov xim yog 16 lab 700 txhiab. Peb hais tias VA (MVA los yog PVA) thiab txhua yam ntawm IPS panels rau hom no.
Qhov tseem ceeb tshaj plaws TN vaj huam sib luag peb pom hauv khw yog txawv. Nws tuaj yeem tsim tau 64 xim R / G / B xwb, thiab qhov ntau tshaj qhov xim tsuas yog 262144. Tab sis yuav kom tau ntau dua 16 lab xim, TN vaj huam sib luag yuav siv cov "jitter" technology peb feem ntau tham txog, yooj yim txoj cai ntawm kev siv tshuab, uas ceev nrooj switches cov xim zoo sib xws siv cov seem ntawm cov tib neeg qhov muag kom tau cov xim uas ploj lawm. Piv nrog rau peb lub ntsiab xim tias 8bit vaj huam sib luag tau muab kom txog rau thaum 255, cov xim qib uas muab los ntawm TN vaj huam sib luag yog qhov tsis ua 0,4, 8, 12, 16, 20, 0,1,2,3,4. Mus txog 252.
Cia wb mus saib ob txoj kev sib txawv ntawm kev siv cov cuab yeej technology:
Thawj txoj kev yog siv tib lub pixel rau tib pixel: tso saib dawb hauv T0 caij, tso saib 4 pauv hauv T1 lub caij pixel, tom qab ntawd ces dawb ntawm T0 caij ntawm T2 lub sij hawm, tso saib 4 theem ntawm grey qib ntawm T3 lub sij hawm, thiab tom qab ntawd sib tov ob hom gray teev cov ntaub ntawv nrog lub qhov muag pom ntawm tib neeg qhov muag, thiab tom qab ntawd tau txais li 2 theem. Grey nplai. .

Tus thawj algorithm
Cia saib seb qhov 1 theem grey siab tiav. Yog thawj hom, T0, T1, T2, peb pixels yuav tso xim dawb, thiab qhov 4 qhab nia tshwm nyob rau lub sij hawm ntawm T3 (vim tias TN pan pixels tsis tuaj yeem saib qhov theem ntawm gray 1, 2, 3), tus saib xyuas tau txais qhov (0 + 0 + 0 + 4) / 4 = 1 theem grayscale, thiab peb kuj tuaj yeem pom nws. Nws yuav siv 4 kauj voj kom tau ib tsos kob, thiab lub sij hawm no yog ntau dua.

Ob tug algorithms
Peb yuav tsum lees tias lub inventions ntawm lub jitter technology tau daws qhov teeb meem ntawm TN panel xim deficiency rau ib yam twg, tab sis qhov no tsis yog ib qho zoo meej daws. Qhov teeb meem ncaj qha yog qhov pom pixel jitter thiab peb theem ntawm 253, 254 thiab 255, txawm tias cov xim jitter yog thov. Cov xim tsuas tawm 0 txog 252 grey nplai thawj xim, yog li cov ntaub ntawv xim kawg tooj yog 253 x 253 x 253 = 16194277, kwv yees li 16.2 M xim.
Cov lus teb: Kuv ntseeg tias ntau tus neeg siv tsis nkag siab.
Sij hawm teb? Yog, nws yog lub sij hawm tshiab rau peb hauv cov hnub nyoog LCD, thiab nws tseem yog qhov qhia tau tias cov tuam txhab LCD tau tsom ntsoov rau lub xyoo dhau los, tab sis thaum koj mus txuas ntxiv rau qhov no, koj yuav pom tau tias nws yog yooj yim tshaj plaws los ua qhov no ntawm qhov ntsuas no.
Nyob rau lub sijhawm teb, qhov kev ua kua dej ua kom pom tseeb yog thawj tus tswv yim los ntawm International Standardization Organization (ISO), thiab qhov standard code ISO13406-2. Lub tswv yim tseem ceeb ntawm qhov kev paub meej yog ua kom muaj kev cuam tshuam cov smoothness thiab clarity ntawm cov duab dynamic ntawm LCD zaub. Cov specification txhais lub sij hawm teb raws li nram no: Thaum lub pixel muab ntawm dawb mus rau dub, qhov electrode voltage hloov ntawm 0 mus rau qhov siab tshaj plaws, uas yog, qhov siab tshaj plaws kev tswj xeev excitation, cov kua siv lead ua kua molecules raug hloov mus rau ib qho chaw tshiab , thiab lub sijhawm uas siv rau hauv txoj haujlwm no yog hu ua lub sijhawm ntxiv. Thaum twg ib pixel muab los ntawm dub mus dawb, qhov voltage ntawm pixels hlais, thiab cov kua siv lead ua kua molecules rov qab los ua txoj hauj lwm ua ntej zog. Lub sijhawm teb tag nrho yog qhov nqi tau los ntawm lub sijhawm ntxiv nrog rau lub sijhawm poob.
Qhov tseeb, qhov pom ntawm ISO qhov kev qhia tawm rau lub ntsiab lus ntawm lub sijhawm teb yog tseem yoojyim heev rau lub sijhawm tsuas yog lub sijhawm hloov ntawm qhov qis pixel dub thiab dawb dub thaum nws siv, thiab tsis muaj ntau yam kev coj qhia thaum ntsuas cov gray nplai hloov thaum lub sijhawm siv los ntsuas. Peb tuaj yeem xav txog ntau tshaj ib xyoo dhau los thaum cov khw muag khoom nrov qhov 12ms kua siv lead ua, "yog lub sijhawm hloov pixel 12ms, tus nqi ntawm qhov kev hloov ntawm ib qho yog 1000/12 = 83, uas yog deb tshaj qhov siab tshaj paub tus nqi ntawm tib neeg 60fps, yog li ntawd 12ms yog qhov kawg ua si kua siv lead ua. " "Tau kawg, 12ms kev ua tau zoo nyob rau hauv qhov kev ua si ntseeg tias cov nyeem ntawv muaj tseeb dua tus sau, tseem pom hauv FPS kev ua si, txog hnub no lub 6ms, 4ms kua kua Crystal, nws cov kev ua tau zoo hauv daim duab hloov ntawm kev ua si tsaws yooj yim CS. Li ntawd, qhov twg ISO puas qhov lub sij hawm teb? Vim li cas thiaj muaj xws li ib tus dev txawv ntawm qhov tseeb?
Ua ntej ntawm tag nrho cov, nyob rau hauv lub ISO specification, tag nrho pixel teb txhais tsuas yog rau 80% ntawm tag nrho pixel nce los yog ua txoj kev. Raws li lub ntsiab txhais ntawm ISO, lub dawb yog hais txog 10% grey qib, cov dub yog hais txog 90% grey qib, thiab ntxiv 20% yog ignored. Lub tswv yim tseem ceeb ntawm tus ISO txhais tau tias tsis yooj yim to taub, vim rau cov kua siv lead ua kua molecules, ob theem ua siv sij hawm-siv. Cov txheej txheem ntawm grey conversion ntawm ob lub hau thiab 20% yog yuav tsis pub dhau lub sij hawm ntawm lub sij hawm teb chaws ISO txhais nws tus kheej, uas tau zoo heev embellish qhov Performance index yog tias qhov no 20% rho, tab sis qhov no yog obviously kev noj. Nws yog tsis ncaj ncees.

Cov lus teb rau cov lus nug
Raws li tau qhia hauv lub sij hawm LCD teb cov lus teev saum toj no, raws li lub ntsiab txhais ISO, lub sij hawm nce siab yog 28.5-12 = 16.5 MS. Tab sis peb pom cov txheej txheem ntawm kev hloov pixel tag nrho ntawm 0% grey mus rau 100% grayscale, uas tau ua dhau tshaj 40 ms thiab mus txog ob zaug ntawm lub ntsiab txhais ISO.
Tau kawg, tus defects ntawm lub ISO txhais tau ntau dua li qhov, qhov loj tshaj plaws uas yog las mees cov xim hloov - uas yog, lub sij hawm rau qhov sib txawv grayscale switching, uas yog tus tshaj plaws zaub peb siv ntawm cov zaub. Los ntawm cov qauv pom hauv LCD, thaum lub pixel hloov los ntawm ib qhov grey ntiav rau ib theem zuj zus, qhov hluav taws xob ntawm ob hnub ntawm qhov pixel los kuj muaj zog. Txawm li cas los xij, piv nrog qhov siab tshaj plaws ntawm qhov kev sib tw dub-thiab-dawb uas tau sau tseg nyob rau hauv ISO specification, qhov sib hla uas siv coj los siv yog qhov tsawg dua thaum lub grayscale hloov tau, yog li nyob rau hauv cov ntaub ntawv no qhov ceev ntawm cov kua tshuaj kua tshuaj molecular reversal teb yuav qeeb down. Nyob rau hauv tib txoj kev, thaum lub tsos nqaij daim tawv hloov ntawm lub grey ntxaum mus rau lub teeb grey nplai, tus txheej txheem yog rov qab, tab sis lub sij hawm no lub corresponding electrode voltage ntawm lub teeb grey scale tsis yog zero, thiab qhov sib xws voltage txawv kuj yuav ua zuj zus, thiab qhov txo qis raws sij hawm yuav ntev zog.

Piav qhia txoj cai
Nws kuj yog vim hais tias tus ISO specification tsis yuam tus neeg muag khoom los mus xav txog lub sij hawm teb ntawm qhov nruab nrab grey teev thaum tus neeg teb rau cov lus teb tsis tau, yog li ntawd tus neeg muag khoom ua haujlwm loj dua. Nws tsis yog ib qho nyuaj rau cov neeg siv nrog kua siv crystal siv dhau los ua kom pom tau tias nyob hauv cov kua hluavtaws ua kua dej ntau dhau ib xyoo dhau los, siv tus phooj ywg AU 16 ms TN vaj huam sib luag qhia tias 16 xuab moo txawm 12 ms ntawm Samsung yog sai dua LG-Philips, uas yog sai tshaj 16 ms IPS luag, thiab nws yog incomprehensible tias lawv muaj qeeb qeeb dua Hydis. Lub 20 xauv moos, uas yog vim tsis muaj cov txheej txheem ISO nrawm lub sijhawm, tau tshwm sim los ntawm tus neeg siv kev xav tsis meej los ntawm lub sij hawm teb lus qhia los ntawm lub khw muag khoom tiag.
Gray nplai teb yog tus pointer nrog siv tus nqi
Raws li peb tau hais los saum toj no, muaj ntau qhov chaw ua haujlwm nyob rau hauv lub ntsiab lus dawb thiab dawb thaum muab los ntawm tus txheej txheem ISO tshwj xeeb tshaj plaws, yog li ntawd cov lus teb rau lub sij hawm yooj yim tsis muaj ntau qhov kev ntseeg siab, yog li cas los ntawm qhov kev xam pom tau ntau dua tus nqi ntawm lo lus teb pointer, lo lus teb yog mus Mus Hauv qhov thib ib nrab ntawm lub xyoo, qee tus tuam ntxhab pib txhawb "grayscale response time".

Gray lus teb sij hawm faib daim duab
Daim duab saum toj no yog ib daim ntawv teev cov lus teb rau daim ntawv pov thawj uas muab los ntawm NEC. Raws li pom hauv daim duab, lub dav hlau X thiab Y axes yog cov pib grey thiab cov ntsuas ntawm qhov ntsuas grates, raws li tus Z axis qhia qhov sij hawm siv thaum lub sij hawm hloov txheej txheem grey. Cia ua tibzoo saib qhov txawv ntawm cov lus teb nyob rau hauv peb lub ntsiab lus txawv: ISO txhais, dawb mus rau gray scale, thiab dub rau lub nplai grey.
ISO lub sijhawm teb = (0-255) 18 + (255-0) 7 = 25 ms
T nws lub sij hawm siab tshaj plaws ntawm cov dawb mus rau ib grayscale = 0 - 192 - 0 = (0-192) 38 + (192-0) 5 = 43 MS (uas yog qeeb dua ISO txhais los ntawm 78%)
Lub sij hawm siab tshaj plaws ntawm dub rau ib grayscale = 255 - 160 - 255 = (255-160) 55 + (160-255) 36 = 91 (uas yog qeeb dua lub ntsiab txhais tau raws li ISO txhais 264%)

Teb cov sij hawm thiab chaw faib daim ntawv qhia ntawm PHILPS 190S5 cov duab
Peb tuaj yeem saib ntawm daim duab saum toj no. Qhov no yog daim ntawv qhia lub sij hawm teb chaw ntawm PHILPS 190S5 cov duab peb tau ua los ntawm peb tus kheej. Tsis zoo li cov lus saum toj no, tus nqe lus qhia ntawm daim duab qhia ncaj qha no muaj ob feem ntawm qhov nce thiab nqis ntuag. Peb pom tau tias qhov ntev tshaj plaws yuav tsum siv qhov chaw nyob hauv ob txoj kab zauv ntawm qhov tob, thiab cov txheej txheem ntawm ntshiab dawb kom dawb huv dub yog ceev tshaj plaws.
Los ntawm cov kev tshawb fawb saum toj no, kuv ntseeg tias tus nyeem ntawv tau muaj kev nkag siab txog lub tswv yim ntawm lub sijhawm teb. Nws kuj pom zoo nrog qhov xaus tias nws yog qhov tsim nyog los muab cov sij hawm tsim nyog gray teev teb kom ua lub sij hawm teb tiag tiag, thiab ua lub sij hawm teb qhov tseeb. Xws li qhov kev txhim kho ntawm tus neeg siv cov ntaub ntawv tiag tiag, nws yog qhov tseem ceeb kom ua qhov hloov ntawm qhov ntsuas ntawm grey thiab nplai gray, uas yog, qhov kev hloov xim ntawm cov xim.
Qhov feem ntau fashionable kua Crystal tshuab "overdrive" xyoo no
Nws yog pom tseeb tias rau cov kua siv lead ua kua teeb meem peb tau sib tham saum toj no, cov chaw tsim tshuaj paus tseem tsis paub ntxiv tias "lub caij dub thiab lub sijhawm teb" propagate, yog li yuav ua li cas txhim kho cov kev ceev ntawm LC hauv lub grey scale switching qhov ua kom pom tseeb ntawm cov tuam ntxhab nyob rau hauv ib nrab ntawm xyoo tas los, "GTG" gray scale teb ceev thiab cov lus teb "overdrive". Tshuab kuj pib tshwm hauv ntau cov khoom siv ua kua qaub (high-end liquid crystal) tshiab hauv lub xyoo dhau los, yog li nws yuav tsum to taub txhua yam ntawm "overdrive".
Hais txog "overdrive", peb tuaj yeem hais qhov FFD technology tsim los ntawm NEC rau LCD TV hauv ob feem ntawm xyoo 2001, thiab nws tuaj yeem suav tias yog thawj qhov ntawm "kev siv nyiaj tshaj". Qhov tseeb, txoj ntsiab cai ntawm cov txheej txheem no yog qhov yooj yim heev. Thaum peb tig qhov dawb (pib ua kua tshuaj lead ua kua molecular lub xeev) rau cov xim dub (cov kua tshuaj ua kua molecule yog nyob rau hauv cov kev taw qhia ntawm lub teeb ntsug hauv lub qhov hluav taws xob) ntawm TN npo, hom nyias hom transistors nyob tom qab ntawm cov kua siv lead ua pixel yog qhov zoo tshaj plaws. Tus txheej txheem ntawm hloov los ntawm dawb mus rau dub yog 20ms. NEC's FFD technology yog xam raws li hauv qab no: vim li cas peb tsis ua ob qhov kev cia siab rau kom tau lub sij hawm sai dua: piv txwv li, ntxiv 2V kom tau lub sij hawm 10 ms. Thiab los ntawm cov ntaub ntawv tshawb fawb los ntawm NEC lub sijhawm ntawd, cov txheej txheem no ua tau. Los ntawm kev ua kom muaj qhov kev vam meej nyob rau hauv qhov ntsuas ntawm qhov hloov grey, kev siv cov txheej txheem hloov grey dua tuaj yeem txo.

Daim phiaj xwm hauv kev tshawb fawb tau muab los ntawm NEC
Peb tuaj yeem saib ntawm daim ntawv nthuav tawm hauv NEC txoj kev tshawb fawb ntawm lub sijhawm, ntawm sab laug uas tsis muaj chaw seem sij hawm teb uas tau ntsuas nrog FFD technology, thaum ntawm sab xis yog qhov kev sim tom qab siv FFD technology, thiab peb pom hais tias, tshwj xeeb tshaj yog nyob rau hauv txheej txheem ntawm gray scale hloov dua siab tshiab, qhov loj tshaj kev txhim kho raug txo tawm ntawm 55ms mus rau 6 ms. Yuav ua li cas peb yuav tsum nco ntsoov yog tias tsis muaj kev hloov hauv cov dawb - Dub - dawb teb ntawm sab laug thiab txoj cai ob sab, thiab peb tuaj yeem nkag siab tau tias vim qhov kev siv qhov hluav taws xob tau siv los ntawm cov electrode hauv cov txheej txheem dawb huv kom dawb yog qhov siab tshaj plaws, yog li tsis muaj laj thawj tsim kho nws. Txawm hais tias NEC tsis tau siv lub tshuab no los rau ntawm cov khoom tawm (vim qhov pib ntawm lub tshuab yog los txhim kho txoj kev kub ceev ntawm LCD TV), Cov Kev Siv Overdrive, uas muaj tib cov kev cai hauv ib nrab hnub ntawm xyoo tas los thiab FFD technology , tau ua nrov rau high thiab nruab nrab - kawg cov lus qhia txog lub LCD.
Qhov tseeb, FFD thiab overdrive yeej yog cov npe, uas yog cov khoom sib txawv, xws li BenQ siv "overdrive", thiab ViewSonic yuav hu tib qho "ClearMotiv", thiab lawv yeej yog tib yam, thiab peb yuav pom dab tsi "overdrive" tuaj yeem muab rau peb. Kev txhawb nqa kev ua tau zoo npaum li cas.

10.png


Kev ua zoo npaum li cas kev txhim kho tau "overdrive" coj tau?
Raws li pom saum toj no, txoj kab xiav xiav saum toj no qhia txog cov txheej txheem ntawm cov tshuaj tiv thaiv tom qab lub cev muaj zog ntawm cov kua qaub tsim kua tshuaj ntxiv nrog rau qhov hluav taws xob, thiab qhov teeb meem muaj qhov sib xws ntawm cov kab dub hauv qab no. Peb pom tau hais tias txij thaum pib ntawm qhov voltage mus rau qhov ruaj ntseg ntawm cov kua siv lead ua kua molecules tsis yog ib qho kev siv tas li, thiab lub teeb xiav point kab nruab nrab yog qhov kev xav tau ntawm cov kua siv lead ua kua. Cov txheej txheem ntawm triggering Overdrive thiab ClearMotiv thiab cov kua siv ua kua dav hauv lies hauv cov tswv yim hluav taws xob. Peb tuaj yeem pom tias yuav ua rau cov kua siv lead ua kua molecules ncav cuag ceev ceev cov tshuaj tiv thaiv, yuav tsum tau siv qhov siab tshaj qhov siab tshaj rau hauv thawj theem pib dua hauv lub xeev. Thaum cov kev coj ntawm cov kua siv lead ua kua molecules yog nyob rau hauv cov kev taw qhia ntawm lub hom phiaj, qhov kev tawm dag zog yog rov qab rau lub qhov muag. Theem ntawm qhov ntsuas ntawm qhov ntsuas.
Los ntawm kev soj ntsuam saum toj no, peb yuav tsum tshem tawm Overdrive thiab nws txoj kev zoo tib yam xws li ua kom txhim kho cov gray scale hloov xim. Ntawm qhov tod tes, nws kuj qhia tau hais tias lub tshuab tsis ua kom txhim kho dawb - Dub dawb - dawb teb, vim hais tias nyob rau hauv qhov kev mob siab heev, qhov excitation voltage thov los ntawm pixels tau mus txog qhov siab tshaj plaws. Tiam sis cov neeg muag khoom tab tom ntsib qhov teeb meem, thiab yog tias cov lus ceeb toom ISO txwm sij hawm yog txhais tias, txawm tias kev siv ntawm Overdrive yuav ua kom zoo rau kev ceev ntawm gray scale hloov dua tshiab, lawv yuav tsis pub kom nce lub sij hawm sib txawv ntawm pawg vaj huam sib luag. Qhov no yog vim li cas peb tau pom lub sij hawm tshiab "GTG Response Time" nyob rau hauv lub xyoo tas los, thaum lub sij hawm tshiab txoj kev xeem tau yug los nrog yug ntawm Kev Siv Overdrive. Hom no tsis ntsuas kev siv ntawm "dawb thiab dawb" hloov nyob rau hauv raws li ISO specification, tab sis lub grey scale switching (qhov sib dua grey kev txiav txim - lub ntsiab grey grey - tus sib zog txiav txim), thiab cov khw yog tus tshiab "GTG lub sij hawm teb "tom qab ntsuas tag nrho cov sij hawm sib luag. Ntawd yog hais tias, dhau los 16ms ISO Performance index mus rau hauv 12 ms G2G hauv ob peb lub lis piam.
Overdrive tsis yog ib hom tshuaj universal
Txawm hais tias peb pom tias daim ntawv thov ntawm Overdrive ua rau cov neeg siv tshuaj tua hluav taws xob tsis zoo rau peb lub tswv yim. Cov exaggeration ntev li ntawm cov khw thiab cov teeb meem ntawm lub tshuab nws tus kheej tsis zoo li lub tshuab siv los ua ib pawg neeg sab nraud. Case.
Thawj yog qhov tshaj tawm ntawm ib co tuam ntxhab, uas yog qhov uas kuv tsis hu lub npe ntawm no, hauv qab no yog los muab Kev Poob Haujlwm Qib Siab Kev Sib Hlwb.

Kev ua tau zoo sib xws ntawm daim duab tom qab siv Overdrive
Los ntawm daim ntawv qhia no, Overdrive yog qhov zoo tshaj plaws, thiab qhov ntsuas gray pom nrog qee cov lus teb txog 80ms kom luv dua 20ms. Tab sis ntev li peb saib zoo zoo, peb yuav pom tias daim duab no tsis yog qhov tseeb. Peb pom tau hais tias lub sijhawm "white black white" ntawm daim duab no tseem raug txo kom tsawg dua 10ms, uas yog tsis yooj yim sua. Raws li peb kev tshawb fawb ntawm Kev Siv Overdrive saum toj no, cov txheej txheem tsis tau txais txiaj ntsim los ntawm Overdrive vim tias "dawb dawb dawb" hloov txheej txheem tau ua siab ntev tshaj qhov kev txhawb zog siab. Ua ib lub khw, xws li kev tshaj tawm yog kev tsis mloog lus.
Tsis tas li ntawd xwb, kuv kawm tau los ntawm kuv cov phooj ywg nyob rau hauv AUO tias qhov tseeb peb pom tib lub ntsiab lus rau TN 16 ms, 12 ms thiab 8 ms, thiab qhov txawv ntawm lub sij hawm yog vim tsav tsheb khiav tsheb thiab daim ntawv thov ntawm Overdrive technology. Nws tseem hais tias qhov tseeb, qhov Tam sim no Overdrive tseem nyob deb ntawm kev sib hloov nrog txhua qhov hloov gray, tsuas yog ib feem ntawm nws, tab sis nws tsis muab tus naj npawb meej, thiab cov ntaub ntawv kawg ntawm lub Summit Overdrive teb yog qhov tseeb ib feem ntawm qhov kev xeem.
Cia wb mus saib cov lus teb ncua sij hawm ntawm lub koom haum Eizo (qhov tseeb, txhua tus paub tias Eizo tsis tsim nws lub vaj huam sib luag, uas yog los ntawm AU).

Tebchaw sij hawm pauv faib daim duab
Raws li pom saum toj no, cov nyhuv ntawm cov overdrive yog obviously yooj yim pom, tab sis cov nyhuv feem ntau sib txawv rau cov xim sib txawv, thiab tsis tag nrho cov xim txiav txim siab yuav tsum tau muab cov ntaub ntawv, thiab feem ntau cov cuab yeej hauv daim duab yog tias tsis muaj dab tsi txawv los ntawm dawb rau txhua tus grey teev ua ntej thiab tom qab siv qhov overdrive.
Tib lub sijhawm, cov chaw tsim khoom lag luam tsis muaj kev tawm tsam tsis zoo rau tus neeg siv khoom thaum lub sij hawm ua teb ISO rau lub sij hawm grey-scale. Raws li lub sij hawm ISO tau txuas ncaj qha mus rau kev tshem tawm cov qis qis tsho LCD, nws zoo li cov nplai gray kom muaj kev cuam tshuam cov pointer, thiab qhov qub ISO grey scale tsis muaj. Dab tsi yog qhov siv tus nqi, ces peb yuav tsis pab wondering yog tias lub sij hawm ntawm grayscale teb tseem yog ib cov nyhuv real, hype ntau dua li cov kev tshaj tawm. Nws hloov tawm tias cov neeg tau txais kev pab xav xav nrhiav cov kua siv lead ua kua uas siv tau rau kev ua si, los yog cia siab rau lawv lub qhov muag kom tau txais cov khoom muag. Nws paub tseeb tias TN yog ua ntej ntawm VA thiab IPS cov khoom vaj khoom tsev rau cov lus teb rau lub sijhawm, thiab yog hais tias qhov kev ua si nyob hauv ib qho tseem ceeb ntawm koj daim ntawv thov siv computer, koj yuav tsum ua kom haum rau xim thiab lwm yam kev qhia zoo. (tom qab ib sab yuav qhia txog cov xim tsis meej ntawm TN version hauv kev nthuav dav).

Qus cov duab qus
Lub BenQ FP91V cov duab, siv qhov kev ceev tshaj 4MS GTG TN vaj huam sib luag, yog CS qhov kev ua si thaum peb siv lub koob yees duab digital los qhib 1/100 thib ob kev kaw lus. Nws tuaj yeem pom tau tias txawm hais tias qhov taw kev khaus heev, qhov kev ntsuam xyuas tus duab ntxoov ntxoo tau pom meej heev, thiab nws yuav hais tau tias cov khoom lag luam tau ua kom tau raws li cov neeg feem coob tau mus ncig. Qhov kev ua si yog nyob rau hauv kev thov.
Cov tswv yim zoo ntawm kev nkag siab txog qhov ci thiab qhov sib txawv ntawm cov kua muaj kua
Lub tswvyim ntawm qhov sib txawv yog los ntawm lub hnub nyoog ntawm CRT, uas yog hais txog qhov ratio ntawm lub ci tshaj plaws pixel thiab qhov tsaus ntuj tshaj plaws pixel nyob rau hauv cov duab tso saib duab. Uas yog hais, thiaj li tau ntau dua qhov sib txawv, peb cia siab tias cov dawb yuav dawb dawb thiab cov dub yuav ntshiab ntau dua. Piv txwv li, peb ntsuas cov kua siv lead ua kua uas muaj lub ci ci ci li ntawm 250 cd / m thiab ib qho dub ci ntawm 0.5 cd / m, thiab qhov sib txawv ntawm cov zaub yog 500: 1 los ntawm cov mis dub / dawb = sib npaug. Raws li lub ntsiab txhais, yog hais tias lub khw tsim los txhim kho qhov ntsuas, tsis muaj kev ntseeg tias muaj ob txoj kev los txhim kho cov purity dub los yog txhim kho cov neeg dawb. Tus qub yog obviously tus caum ntawm txhua lub chaw tsim (vim hais tias cov kua dub yog tsis ntshiab), thiab tom kawg yog yooj yim rau kev siv.
Ua ntej saib thawj txoj kev los txhim kho cov kev coj dawb paug, uas tsis tuaj yeem ua rau cov khw muag khoom, tab sis cov kev sib raug zoo ntawm kev sib txig yog ntau dua, kev txhim kho lub lim qauv los yog kev txhim kho txoj kab sib ntsaws ntawm cov kua siv lead ua kua molecules los txhim kho cov qoob loo. Hauv kev sib piv, nws yog qhov yooj yim dua txhawm rau txhim kho dawb dawb rau cov neeg lag luam, nce lub xov tooj ntawm cov teeb, hloov lub teeb ntawm lub teeb, ua kom cov hauj lwm zoo ntawm cov teeb qhia ntawm lub teeb thiab ua rau, thiab tsis tas yuav tsum ua tsab xov xwm nyob rau hauv lub kim tshaj plaws siv lead ua kua.
Cia peb mus ua piv txwv. Tam sim no backlight module muaj ib theem ntawm kev tsim ntawm 500 cd / m dawb ci ntsa iab, thaum lub txiaj ntsig dub ci tseem ceeb nyob ntawm tus thawj 0.5cd / m theem, thiab tom qab ntawd peb tuaj yeem tau txais 500 / 0.5 = 1000: 1 ntau dua tsis sib xws . Tab sis qhov tseeb, xws li ib qho screen yuav tsuas brighten neeg vertigo.
Nyob rau hauv qhov tseeb, ntau cov phooj ywg uas siv tus Minister ntawm kua siv lead ua yuav zoo li muaj kev cuam tshuam ntau lub qhov muag tshaj li tus thawj CRT. Nyob rau hauv qhov tseeb, lawv yog tshwm sim los ntawm kev siv ntawm lub neej ntawd kev ci ntsa iab. Nws yog tsim nyog yuav tsum paub hais tias qhov tseem ceeb ntawm qhov ntev ntawm kev nyeem ntawv ua hauj lwm tau pom zoo los ntawm tus kws tshaj lij yog 110 cd / m, thaum lub teeb pom kev zoo ntawm cov ntaubntawv.CRT yog 90 cd / m. Tsis txhob hais cov lus tseem ceeb. CRT yog ci ntsa iab thiab nyeem tsis tau tom qab qhib. Rau kev paub, lub 250 cd / m thiab txawm ntau dua qhov ci ntawm cov kua siv lead ua kua qaub tam sim no nws kuj qaim. Nws yog vim hais tias lub siab brightness ua rau tus neeg siv lub qhov muag mus rau accelerate qaug zog, xav ntau dua tsis khov dua li cov CRT. Yog tias koj ntsib qhov teeb meem no, kuv xav kom koj kho qhov kaj ci ntawm LCD mus rau qhov chaw uas tsim nyog.
Yog li ntawd, vim li cas ho tsis ua rau lub khw muag khoom ua kom siab li ntawd nws tsis haum rau kev siv, uas, ntawm chav kawm, tuaj yeem txhim kho tus neeg siv kev paub txog multimedia, xws li kev yees duab, thiab qhov thib ob yog siv qhov nce hauv qhov ci ua kom zoo nkauj zoo nkauj. Qhov no kuj yog ib qhov nyob hauv ISO qhov sib txawv ntawm qhov kev qhia tshwj xeeb, vim hais tias qhov kev qhia tsis meej hais tias tag nrho cov khoom yuav tsum raug ntsuas ntawm tib lub txiaj ntsig dawb ci, xws li 110 cd / m, los ntsuas cov luminance ntawm lub sijhawm no. Nyob rau hauv cov ntaub ntawv ntawm cov teeb meem ntawm kev txhim kho cov purity ntawm kua siv lead ua dub, manufacturers yuav ib txwm siv lub nce qib ntawm kuj yooj yim ci ci.

Tshaj tawm daim duab
Raws li deb li qhov kev siv tshuab hluav taws xob, qhov sib npaug ntawm IPS thiab VA lub vaj huam sib luag zoo dua li ntawm TN, thiab qhov sib txawv ntawm 700: 1 kuj yog ib txoj kev los qhia qhov txawv ntawm pawg VA. Qhov loj ntawm qhov qub ob yog tias qhov kev kawm dub yog zoo tshaj qhov TN vaj huam sib luag. Ntawm chav kawm, nws yog hais txog cov kev pab ntawm siab sib piv. Kuv tsis tau hais tias nws nyob ntawm no. Ntshiab dub tuaj yeem ua daim duab ntau dua, nplua nuj nyob hauv ntau ntau, thiab cia peb pom ntau dua thaum peb saib cov duab thiab cov nyuab disks. Nyob rau tib lub sij hawm, qhov zoo sib xws dua rau cov neeg uas ua ntawv tsis zoo tuaj yeem txhim kho qhov kev xav ntawm qhov kev ua si, ntxiv rau, yog tias nws yog CS xws li kev ua si, nws tuaj yeem yuav yooj yim rau kev ceev faj thaum tus yeeb ncuab, tau kawg, rau qhov yooj yim nrhiav ntawm qhov kev ua tau zoo ntawm qhov kev ua si yog qhov zoo tshaj qhov kev xaiv ntawm ib qho screen zoo zoo CRT.
