LED tag nrho-xim zaub daim ntawv thov feem ntau nyob rau hauv lub xeev ntawm looping video, thiab qhov 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 sim. dim. Qhov no yog hu ua smear phenomenon.
LED puv xim zaub smear
Lub ntsiab ua rau smear phenomenon yog raws li nram no:
① teeb meem ntawm daim npav tsav tsheb: Koj tuaj yeem sim hloov kho daim npav tsav tsheb lossis rov nruab tus tsav tsheb daim npav. 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, ntxuav cov ntiv tes kub, thiab saib seb cov kiv cua ntawm daim npav ua haujlwm zoo li cas.
③Data cable teeb meem: Koj yuav tsum tau hloov cov ntaub ntawv cable los xyuas, lossis xyuas seb cov ntaub ntawv cable puas yog khoov.
④ Cov teeb meem ntawm cov kab hluav taws xob: VGA cable, xyuas seb cov kab no txuas puas zoo 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 Teeb pom kev teeb meem: Txuas cov zaub rau lwm lub khoos phis tawj ib txwm muaj. Yog tias qhov teeb meem tshwm sim, nws yuav yog teeb meem zaub.

Cov cuab yeej tiv thaiv duab ntxoov ntxoo ntawm lub vijtsam LED tuaj yeem ua rau lub vijtsam zaub ntau dua, kom lub vijtsam tuaj yeem 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 LED zaub screen kom tau raws li daim ntawv thov uas tsis muaj nqi thiab txuag hluav taws xob ib puag ncig kev tiv thaiv; qhov refresh tus nqi yog qhov siab dua cov zaub, qhov ruaj khov ntawm cov zaub, uas muab kev txhawb nqa rau cov khoom zoo thiab cov khoom zoo, thiab cov khoom siv no kuj ua rau tib neeg lub qhov muag tsis tshua muaj zog, thiab tib lub sijhawm tuaj yeem ua tau raws li qhov xav tau ntawm high-speed shooting. Nws yog tib yam nkaus, uas tau txhawb nqa kev txhim kho ntawm txhua yam, thiab tseem tau txhawb nqa kev txhim kho ntawm tag nrho LED zaub daim ntawv thov thev naus laus zis.
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.

Txhawm rau txo qis kev siv hluav taws xob ntawm LED cov lus qhia, 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 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 lub computer graphics tsav tsheb, los xyuas kom meej cov duab zoo, thiab thaum kawg paub qhov precision high-txhais zaub ntawm tag nrho-xim LED zaub.
