Qhov no yog qhov refresh npaum li cas.
Tus nqi refresh yog muab faib ua ntsug refresh npaum li cas thiab kab rov tav refresh npaum li cas. Qhov refresh npaum li cas feem ntau hais txog qhov ntsug refresh npaum li cas. Qhov ntsug refresh tus nqi sawv cev rau tus naj npawb ntawm lub sij hawm lub vijtsam duab redrawn ib ob, uas yog, tus naj npawb ntawm cov tshuaj ntsuam refreshes ib ob, hauv Hz (hertz). Qhov siab dua qhov refresh npaum li cas, cov duab zoo dua, cov duab zoo dua, thiab qhov cuam tshuam me me ntawm qhov muag. Qhov qis dua qhov refresh npaum li cas, cov duab flickers ntau dua, thiab qhov muag nrawm dua. Feem ntau hais lus, yog tias koj tuaj yeem ua tiav qhov ntsuas siab dua 80Hz, koj tuaj yeem tshem tawm tag nrho cov duab flicker thiab jitter, thiab koj ob lub qhov muag yuav tsis nkees dhau. Pom tseeb, qhov siab dua qhov refresh npaum li cas, qhov zoo dua, tab sis nws raug nquahu kom koj tsis txhob cia lub monitor ib txwm ua haujlwm ntawm qhov siab tshaj plaws refresh tus nqi, uas yuav ua rau kom cov laus ntawm CRT raj, feem ntau yog ib lossis ob qhov qis dua qhov siab tshaj plaws refresh tus nqi. yog qhov tsim nyog dua, thiab 85Hz tau pom zoo. Lub hauv paus ntsiab lus teeb pom kev zoo ntawm cov kua siv lead ua kua (LCD) txawv ntawm CRT ib txwm muaj. Txij li txhua qhov taw qhia ntawm cov kua siv lead ua kua zaub tswj cov xim thiab ci ntsa iab tom qab tau txais cov teeb liab, nws tsis tu ncua emits lub teeb es tsis txhob siv lub teeb ci cathode (CRT). ) Nws yog ib qho tsim nyog yuav tsum tau hloov kho cov ntsiab lus tseem ceeb tas li. Yog li ntawd, lub LCD splicing npo muaj cov duab zoo thiab yeej tsis flickers, uas txo qhov muag nkees kom tsawg. Tus nqi refresh muaj lub ntsiab lus tseem ceeb rau CRT. Qee zaum, LCD refresh tus nqi yog siab heev, tab sis nws yuav cuam tshuam rau nws lub neej kev pabcuam thiab khaws cia ntawm 60-75.
Muaj feem cuam tshuam:
Los ntawm kev pom kho vajtse, qhov tseem ceeb tshaj plaws cuam tshuam rau tus nqi refresh yog bandwidth ntawm cov zaub. Tam sim no qhov dav dav 17-nti xim zaub muaj qhov bandwidth ntawm 100, uas tuaj yeem ncav cuag 85 Hz. Qhov loj ntawm lub vijtsam, qhov loj dua qhov bandwidth, 19 ntiv tes yog li 200.21 ntiv tes yog li 300, tib xim thiab tib qhov loj, qhov bandwidth siab dua, qhov kim dua. Qhov thib ob, muaj daim npav graphics uas cuam tshuam rau tus nqi refresh. Graphics phaib kuj muaj cov nqi hloov tshiab thiab cov kev daws teeb meem, tab sis hais txog cov nqi tshiab, qhov no yog qhov tsis txaus ntseeg tam sim no, vim tias qhov no feem ntau yog rau cov ntawv teev hnub qub, thiab tam sim no txawm tias daim npav qub TNT2 daim duab qub. Nws tseem tuaj yeem txhawb nqa 1024 * 1024 * 768 daws teeb meem, uas yog tus qauv daws teeb meem ntawm 17-nti CRT saib. Yog li, qhov tseem ceeb tshaj plaws cuam tshuam rau tus nqi refresh yog bandwidth ntawm cov zaub.
