Txoj kev loj hlob ntawm cov khoom yog inseparable los ntawm lub real-time hloov technology. Txij li thaum txoj kev loj hlob ntawm tag nrho-xim LED zaub kev lag luam, ntau cov khoom tsim technologies tau sau. Ntawm lawv, yug ntawm cov xim puv xim LED yog ib qho kev ua tiav. Tam sim no, LED cov xim puv xim tau siv dav, thiab lawv cov kev siv zog tau maj mam nce. Yog li, dab tsi tseem ceeb zaub yees ua LED puv xim zaub npog? Niaj hnub no, tus editor coj txhua tus los tham txog kev tshem tawm cov duab ntxoov ntxoo ntawm cov xim puv xim coj zaub! Cov xim puv xim LED cov duab ntxoov ntxoo-tshem tawm tshuab puv xim LED cov duab ntxoov ntxoo-txo tshuab tuaj yeem ua rau lub vijtsam zaub ntau dua thiab ua rau lub vijtsam zaub ncav cuag cov duab zoo; Kev siv hluav taws xob tsawg tuaj yeem txuag hluav taws xob thaum lub sij hawm siv lub sij hawm ntev ntawm cov xim puv LED Cov qauv ua tau raws li cov kev cai ntawm kev siv qis thiab kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig; qhov siab dua qhov refresh npaum li cas, qhov ruaj khov ntawm cov zaub screen, uas muab kev txhawb nqa rau cov lus pom zoo thiab cov khoom zoo, thiab cov khoom siv no kuj ua rau tib neeg lub qhov muag zoo li qaug zog, thiab tuaj yeem ua tau raws li qhov xav tau ntawm kev tua hluav taws kub ceev. Nws yog tib yam nkaus, uas tau txhawb nqa kev txhim kho ntawm txhua yam, thiab tseem tau txhawb nqa txoj kev loj hlob ntawm tag nrho cov xim LED zaub daim ntawv thov technology. Tam sim no tshem tawm technology rau tag nrho-xim LED zaub

Smear phenomenon
Vim li cas cov nyhuv de-imaging tseem ceeb heev hauv LED puv xim zaub? Vim hais tias tag nrho-xim LED zaub daim ntawv thov feem ntau nyob rau hauv lub xeev ntawm looping video, thiab cov dynamic zaub no yuav tsub tus parasitic capacitance ntawm kab los yog kab kab thaum kab hloov, ua rau ib co LED teeb uas yuav tsum tsis txhob ci nyob rau hauv lub caij ntuj no. tshwm dim, Qhov no yog hu ua smear phenomenon.
Lub ntsiab ua rau smear phenomenon yog raws li nram no:
① Graphics card tsav teeb meem. Koj tuaj yeem sim hloov kho daim npav daim npav tsav tsheb lossis rov nruab dua daim npav tsav tsheb. Nyob rau tib lub sijhawm, nws raug nquahu kom kho qhov kev daws teeb meem thiab hloov tshiab, uas kuj tseem yuav cuam tshuam nrog lub sijhawm teb ntawm LCD.
② Graphics card teeb meem. Koj tuaj yeem sim rov ntsaws thiab ntxuav cov ntiv tes kub, thiab tib lub sijhawm, koj tuaj yeem soj ntsuam seb cov kiv cua ntawm daim npav ua haujlwm zoo li cas.
③Data kab teeb meem. Yuav tsum tau hloov cov ntaub ntawv cable kom pom, lossis xyuas seb cov ntaub ntawv cable puas yog khoov.
④ Teeb meem kab kab. Ntawd yog, VGA cable. Xyuas seb lub cable no txuas zoo li cas thiab seb puas muaj qhov xoob. Koj tuaj yeem sim VGA cable zoo, thiab VGA cable yuav tsum nyob deb ntawm lub hwj chim qaum.
⑤ Cov teeb meem pom. Txuas lub monitor rau lwm lub khoos phis tawj qub. Yog tias qhov teeb meem tshwm sim, nws yuav yog teeb meem saib xyuas.
Qhov tshwm sim smear yog ib qho teeb meem kev lag luam uas nyuaj los daws hauv kev lag luam ua ntej. Qhov no kuj muaj feem xyuam rau cov cuab yeej tiv thaiv duab ntxoov ntxoo ntawm cov xim puv xim LED. Yog tias tam sim no cov nyhuv tiv thaiv duab ntxoov ntxoo ntawm tag nrho cov xim LED zaub tsis zoo, qhov tshwm sim smear yuav cuam tshuam rau qhov zoo ntawm cov duab duab. . Yog li ntawd, nyob rau hauv cov nqe lus ntawm high-txhais zaub ntawm ib tug tag nrho-xim LED zaub, tus duab ntxoov ntxoo tshem tawm technology yog ib qho tseem ceeb heev.
Full xim coj zaub
Tsis tas li ntawd, txij li txhua kab kab thiab kab kab ntawm tag nrho cov xim LED zaub muaj cov kab mob cab, cov kab mob cab kab mob ntawm kab kab yuav cuam tshuam rau lub sijhawm nce thiab poob ntug ntawm qhov chaw nres nkoj ntawm tus neeg tsav tsheb nti, uas yuav cuam tshuam rau cov zaub. Cov nyhuv ntawm cov nti thaum nws tsis tshua muaj grey, thiab yuav ua rau smear phenomenon. Qhov tshwm sim smear yog qhov pom tseeb heev thaum lub vijtsam LED "slashed": LED teeb nyob rau hauv cov zaub ib txwm, nce thiab nqis (los yog sab laug thiab sab xis) txoj haujlwm yuav dimmed.
Thaum ROW(n) kab qhib, cov kab mob cab cab Cc yuav raug them los ntawm lub teeb 1 uas qhib; thaum ROW (n ntxiv rau 1) kab yog qhib, tus kab mob cab capacitance Cc tseem yuav raug them los ntawm lub teeb 2, ua rau lub teeb 2 yuav dimly teeb. .
Tam sim no erasing technology zoo tshem tawm cov smear phenomenon. Thaum ROW(n) kab thiab ROW(n ntxiv rau 1) kab hloov, qhov tam sim no erasing muaj nuj nqi cia li tsub tus parasitic capacitance Cc, thaum lub ROW (n ntxiv rau 1) kab Thaum nws qhib, tus kab mob cab Cc yuav tsis ua. them los ntawm lub teeb 2, yog li tshem tawm cov smear phenomenon.
Yuav kom txo tau lub zog noj ntawm cov xim puv xim LED, cov khoom siv hluav taws xob tsawg tau qhia. Los ntawm kev txo qhov tam sim no inflection point voltage, lub hwj chim mov voltage ntawm tag nrho-xim LED zaub yog txo. Txoj kev no kuj txo cov hluav taws xob hluav taws xob, yog li 1V resistor uas yuav tsum tau txuas nrog lub teeb liab tuaj yeem raug tshem tawm. Los ntawm ob qhov kev txhim kho no, kev siv hluav taws xob tsawg, kev siv tau zoo tuaj yeem ua tiav.
Nyob rau hauv luv luv, txawm hais tias nws yog tus duab ntxoov ntxoo tshem tawm technology los yog tam sim no tshem tawm technology, lub luag haujlwm tseem ceeb ntawm lub tshuab tsav yog ua kom daim duab ruaj khov thiab meej, ib yam li daim npav tsav tsheb ntawm lub khoos phis tawj, los xyuas kom meej cov duab zoo, thiab Thaum kawg paub txog cov lus qhia meej meej ntawm cov xim puv xim LED.
