Uas saib yog qhov zoo tshaj plaws mus yuav?
Thaum lub sij hawm no thiab lub sij hawm, CRT raws li kev soj ntsuam yog ib qho kev siv technology dhau los. Yeej tseem zoo nkauj tag nrho ntawm cov cathode cov tshav dav hlau cauj tau raug txwv vim yog cov nqi thiab ib puag ncig kev txhawj xeeb. Vim li no, koj yuav yuav tsis txawm nrhiav tau ib qho khoom rau kev muag khoom. Xwb, tag nrho cov thev naus laus zis yog LCD ua tsaug rau kev txhim kho technology uas ua rau lawv zoo dua rau cov xim, saib cov ces kaum thiab txawm tawm sab nraud ntawm lawv cov kev daws teeb meem.
Feem ntau lub tshuab computer siv tam sim no los ntawm kev pheej hmoo tuaj nrog LCD ntsuas. Tseem rau cov uas paub txog qhov txawv thiab qhov uas lawv yuav zoo dua ntawm kev yuav khoom, peb tau hloov kho tshiab hauv tsab xov xwm no kom muaj ntau yam tseem ceeb tshaj rau cov kev yees siv tam sim no thiab cov khoom muaj hnub no.
CRTs
Qhov zoo tshaj plaws uas CRT saib xyuas nyob rau LCDs tau lawv cov xim rendering. Qhov sib piv ntawm qhov sib txawv thiab qhov tob ntawm cov xim tau tshwm sim muaj ntau dua nrog CRT tus saib dua li LCDs. Thaum lub sij hawm no tseem muaj tseeb nyob rau hauv feem ntau, ntau lub strides tau ua nyob rau hauv LCDs xws li qhov sib txawv no tsis zoo li thaum nws ib zaug. Ntau cov qauv nraaj tseem siv cov CRT loj loj saib xyuas lawv cov haujlwm vim cov xim zoo. Ntawm chav kawm, qhov kev muaj peev xwm no tsis tuaj yeem degrade lub sijhawm raws li cov phosphors hauv lub raj tawg.
Lwm qhov zoo dua tias CRT cov saib xyuas nyob rau hauv cov ntxaij vab tshaus hauv LCD yog rab peev xwm yooj yim mus rau ntau yam kev txiav txim siab. Qhov no yog hu ua multisync los ntawm kev lag luam. Los kho kho txoj hlua hluav taws hauv lub raj, lub vijtsam tau yooj yim kho kom qis qis qis qis dua thaum khaws cov duab meej meej lawm.
Thaum no ob yam khoom yuav los ua ib qho tseem ceeb rau CRT tus saib, muaj kev tsis zoo thiab. Qhov loj tshaj ntawm cov no yog qhov loj thiab qhov hnyav ntawm cov leeg. Qhov sib npaug ntawm qhov sib npaug ntawm LCD qhov sib npaug yog nce siab txog 80% me me thiab qhov hnyav dua piv rau CRT raj. Qhov loj qhov screen, qhov loj qhov txawv qhov txawv. Lwm qhov teeb meem loj tseem ceeb nrog lub hwj chim noj. Lub zog uas tsim nyog rau cov hlau hauv electron txhais tau hais tias saib cov neeg siv khoom thiab tsim kom muaj cua kub ntau dua li cov LCD monitor.

LCDs
Qhov loj tshaj plaws rau LCD monitors yog qhov loj me thiab qhov hnyav. Raws li tau hais ua ntej, qhov luaj li cas thiab qhov hnyav ntawm lub LCD monitor yuav ua kom siab tshaj ntawm 80% sib dua li qhov sib npaug ntawm CRT npo. Qhov no ua rau nws muaj peev xwm ua rau cov neeg siv cov vijtsam loj dua rau lawv cov computers ntau tshaj yog ua ntej.
Cov ntxaij vab tshaus tseem yuav ua kom muaj lub qhov muag tsawg dua rau tus neeg siv. Qhov teeb meem tsis muaj teeb meem thiab kev xaav ntawm ib lub raj roj hmab CRT yuav ua rau cov neeg hnyav ntawm cov neeg siv hnyav. Qhov qis siv ntawm LCD ntsuas tau nrog lawv qhov kev tshuaj xyuas tas li ntawm pixels nyob los yog tawm ua qaug zog rau tus neeg siv. Nws yuav tsum raug sau tseg tias qee cov neeg tseem muaj teeb meem nrog lub teeb pom kev zoo siv nyob rau hauv qee lub LCD backlights. Qhov no tau raug offset los ntawm kev siv cov LEDs ntau dua li cov hlab ntws fluorescent.
Qhov tseem ceeb tshaj plaws rau cov ntxaij lim dej hauv LCD yog lawv qhov kev txiav txim siab lossis cov kev daws teeb meem . Ib lub vijtsam LCD tsuas pom cov pixels hauv nws lub matrix thiab tsis pub ntau dua. Nws tuaj yeem tso saib qhov kev daws teeb meem hauv ib ntawm ob txoj hauv kev. Siv ib feem ntawm tag nrho cov pixels ntawm lub tso saib los yog dhau extrapolation. Extrapolation yog ib txoj hauv kev uas lub monitor muaj ntau yam pixels ua ke kom simulate ib qho me me pixel. Qhov no feem ntau tuaj yeem ua rau cov duab thev plaub lossis cov duab zoo nkauj tshwj xeeb nrog cov ntawv thaum khiav qhov screen hauv qab no yog ib qho kev daws teeb meem. Qhov no tau zoo heev hauv xyoo uas nws tsis yog qhov teeb meem ntxiv lawm.
Cov yees duab yog teeb meem nrog LCD saib xyuas thaum ntxov vim qeeb dua cov lus teb. Qhov no tau raug kho los ntawm ntau cov kev txhim kho, tab sis kuj muaj qee cov uas tseem muaj sij hawm tsawg. Cov neeg yuav khoom yuav tsum paub txog qhov no thaum yuav khoom. Txawm li cas los xij, kev txhim kho feem ntau yog kev ua haujlwm uas yuav ua tau rau lwm qhov teeb meem ntawm cov xim kom pom tseeb. Hmoov tsis, txoj kev ua lag luam tsis zoo heev txog kev teev cov lus qhia rau cov neeg saib xyuas los pab cov neeg yuav khoom to taub thiab sib piv cov saib xyuas.
