Daim ntawv no tham txog cov laj thawj thiab cov kev daws teeb meem ntawm kev rub tshwm sim ntawm cov xim puv xim LED siab-txhais me me qhov sib nrug zaub screen!
LED tag nrho-xim zaub daim ntawv thov feem ntau nyob rau hauv lub xeev ntawm kev ua si video nyob rau hauv ib lub voj, thiab qhov dynamic zaub no yuav tsub tus parasitic capacitance ntawm kab los yog kab thaum kab hloov, ua rau ib co LED teeb uas yuav tsum tsis txhob yuav taws ntawm no. lub sij hawm los tshwm tsaus nti, uas yog hu ua "drag duab ntxoov ntxoo" phenomenon.
Lub ntsiab yog vim li cas rau lub dragging phenomenon yog raws li nram no:
① teeb meem ntawm daim npav tsav tsheb.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 kev hloov tshiab, uas kuj tseem yuav cuam tshuam nrog lub sijhawm teb ntawm LCD zaub.
② teeb meem daim npav video.Koj tuaj yeem sim ntsaws nws dua thiab ntxuav tus ntiv tes kub.Nyob rau tib lub sijhawm, koj tuaj yeem saib seb daim npav daim npav kiv cua ua haujlwm li cas.
③ teeb meem kab.Nws yog tsim nyog los hloov cov ntaub ntawv cable los yog xyuas seb cov ntaub ntawv cable yog khoov.
④ Teeb meem kab teeb.Ntawd yog, VGA cable.Xyuas seb lub cable no txuas zoo li cas thiab seb nws puas xoob.Sim hloov qhov zoo VGA cable.Tsis tas li ntawd, VGA cable yuav tsum nyob deb ntawm lub hwj chim cable.
⑤ Teeb pom kev teeb meem.Txuas lub monitor mus rau lwm lub computer ib txwm.Yog tias qhov teeb meem tshwm sim, nws yuav yog qhov teeb meem saib xyuas.
Cov duab ntxoov ntxoo tshem tawm cov cuab yeej ntawm LED zaub npo tuaj yeem ua rau cov duab cov duab zoo dua thiab ua rau cov duab tso tawm kom ncav cuag lub siab txhais 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 ua tau raws li qhov yuav tsum tau ua ntawm cov nqi 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 duab duab, 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 nkees thaum saib, thiab tuaj yeem ua tau raws li cov kev xav tau ntawm kev yees duab nrawm.Nws yog qhov tseeb uas tau txhawb nqa kev txhim kho ntawm cov nyhuv hauv txhua yam, thiab tseem txhawb nqa kev txhim kho ntawm daim ntawv thov thev naus laus zis ntawm tag nrho LED zaub screen.
Tam sim no tus duab ntxoov ntxoo tshem tawm technology zoo tshem tawm cov phenomenon.Thaum ROW (n) kab thiab ROW (n + 1) kab hloov kab, cov duab ntxoov ntxoo tshem tawm tam sim no cia li them tus kab mob parasitic capacitance Cc.Thaum ROW (n + 1) kab yog nyob rau, tus kab mob cab capacitance Cc yuav tsis raug them los ntawm lub teeb 2, yog li tshem tawm qhov tshwm sim tshwm sim.
Txhawm rau txo qis kev siv hluav taws xob ntawm LED cov lus qhia, cov khoom siv hluav taws xob tsawg tau qhia.Txo lub hwj chim mov voltage ntawm LED zaub screen los ntawm kev txo qhov tam sim no inflection point voltage.Txoj kev no kuj txo cov hluav taws xob hluav taws xob, uas tuaj yeem tshem tawm qhov tsis kam ntawm 1V voltage poob uas yuav tsum tau txuas nrog hauv series rau lub teeb liab.Los ntawm ob qhov kev txhim kho no, kev siv hluav taws xob tsawg thiab kev siv tau zoo tuaj yeem ua tiav.
Nyob rau hauv luv luv, txawm hais tias nws yog cov cuab yeej tshem tawm lossis cov cuab yeej tshem tawm tam sim no, lub luag haujlwm tseem ceeb tshaj plaws ntawm lub tshuab tsav tsheb yog ua kom cov duab ruaj khov thiab meej, ib yam li lub computer graphics card tsav, kom ntseeg tau tias cov duab zoo, thiab thaum kawg ua tiav. lub precision high-txhais zaub ntawm tag nrho-xim LED zaub.
