DVI interface tau muab faib ua 3 pawg thiab 5 tus qauv. Txhua tus qauv muaj nws daim ntawv thov ntau yam. Yog tias nws siv yam tsis muaj qhov sib txawv, nws yuav cuam tshuam rau kev ua haujlwm ntawm tus ntaus zaub.
Yog li ntawd, raws li ib qho kev teeb tsa tawm ntawm cov qauv interface, nws tseem tsim nyog rau peb kom nkag siab txog DVI!
Lub npe puv ntawm DVI yog Digital Visual Interface. Nws tau tsim nyob rau xyoo 1999 los ntawm SILICon Image, Intel (Intel), Compaq (Compaq), IBM, HP (HP), NEC, Fujitsu (Fujitsu) thiab lwm lub tuam txhab los tsim DDWG (Digital Display Working Group). Pab Pawg Ua Haujlwm Digital Display) qhia cov txheej txheem interface.
Nws yog raws li Silicon Duab' s PanalLink interface thev naus laus zis, raws li TMDS (Kev Hloov Hloov Me Me Sib Txawv) cov kab ke hluav taws xob ua lub hauv paus hluav taws xob sib txuas. TMDS yog cov teeb meem txawv cov teeb liab uas tuaj yeem encode pixel cov ntaub ntawv thiab kis nws los ntawm cov ntawv sib txuas. Cov teeb liab digital tsim los ntawm daim npav daim npav yog tshaj tawm los ntawm cov khoom xa tawm raws li TMDS cov txheej txheem thiab tom qab ntawd xa mus rau lub txais khoom los ntawm TMDS channel, thiab tom qab ntawd xa mus rau lub digital display device tom qab txiav txim siab.
DVI interface tus pin txhais
Lub DVI tso saib kab ke muaj xws li lub transmitter thiab tus txais. Cov khoom xa tawm yog qhov chaw ntawm lub teeb liab, tuaj yeem tsim rau hauv daim npav npav kis las lossis tshwm rau ntawm daim npav duab npav PCB hauv daim ntawv ntawm ib qho txuas ntxiv; thaum lub txais hluav taws xob yog Circuit Court ntawm cov zaub uas tuaj yeem txais cov cim hluav taws xob, txiav txim siab rau lawv thiab xa tawm hauv qhov digital digital Circuit, los ntawm ob qho no, cov teeb liab xa los ntawm daim npav daim duab ua cov duab ntawm cov zaub.
Piv nrog rau cov teeb meem VGA tsoos, cov kua siv lead ua zaub coj los ua raws li DVI cov teeb liab tsis muaj teeb meem ib theem thiab yuav tsis ua rau lub teeb lub nrig. Tsis tas li ntawd, tom qab siv DVI cov teeb liab, cov zaub yuav tsis ua rau muaj kev cuam tshuam geometric, uas zoo heev txhim kho qhov zoo ntawm daim duab.
Cov qauv sib txawv ntawm DVI
Txawv ntawm VGA interface, muaj ntau cov qauv rau DVI interface, yog li koj yuav tsum to taub nws thaum siv cov ntsuas.
Raws li koj tuaj yeem pom los ntawm daim duab hauv qab no, DVI tau muab faib ua 5 tus qauv. Ntawm lawv, DVI-D thiab DVI-Kuv tau muab faib ua ob hom," dual channel" thiab" ib qho channel" ;. Dab tsi peb feem ntau pom yog cov channel nkaus xwb. Tus nqi ntawm dual channel version yog qhov siab heev, yog li tsuas yog qee cov khoom siv ua haujlwm tau. , Nws yog qhov nyuaj rau cov neeg tau txais txiaj ntsig pom.
DVI-A yog qhov qauv kis tau tus mob sib kis, uas tuaj yeem pom nyob rau yav tom ntej loj-npo kev tshaj lij CRT. Txawm li cas los xij, vim tias nws tsis muaj qhov tseem ceeb sib txawv ntawm VGA thiab nws qhov kev ua tau zoo tsis siab, DVI-A tau raug tso tseg. Raws li rau DFP interface, qhov no yog qhov tshwj xeeb ua ntej digital uas tau muab tso tseg.
Dab tsi yog qhov sib txawv ntawm 18-pin thiab 24-pin?
Hauv kev ua lag luam, feem ntau peb tuaj yeem hnov cov neeg muag khoom piav qhia txog plaub yam tshwj xeeb ntawm DVI cable li 18+1 thiab 24+1 thiab 18+5 thiab 24+5.
Qee tus neeg hais tias 18-tus pin yog qhov yooj yim dua, thiab qhov ua tau zoo tsis zoo li 24-tus pin. Qee tus neeg hais tias qee qhov 24 pins yog lub xov hluav taws xob hauv av, tab sis cov nyhuv yog zoo tib yam li 18-tus pin. Cov ntawm cov nqe lus no puas muaj tseeb?
Qhov tseeb, peb twb qhia tawm cov ntsiab lus hauv cov lus saum toj no. 18-tus pin yog ib-tshooj DVI, thiab tus xa xov tsuas yog ib nrab ntawm qhov ntawm 24-tus pin, uas yog 165MHz. Ntawm lub vijtsam zaub, qhov kev daws teeb meem txhawb los ntawm ib-channel DVI yeej zoo tib yam nkaus li ntawm dual-channel, tab sis tus nqi kho dua tshiab tsuas yog ib nrab ntawm cov ntawm ob-channel, uas yuav ua rau cov zaub tsis zoo. Feem ntau hais lus, qhov siab tshaj plaws ntawm qhov ua kom zoo nkauj ntawm ib-channel DVI interface tsuas yog txhawb tau 1920 * 1080 * 60hz lossis 1600 * 1200 * 60hz, uas yog, cov coj ua qub ntawm 23-nti widescreen zaub thiab 20-nti coj piv, yog tias nws siab dua Nws yuav ua rau cov ntawv poob qis.
Txog tam sim no, peb cov LCD saib feem ntau tseem nyob ib puag ncig 19-nti ib qho screen thiab 20-inch widescreen. Tsawg tsawg leej neeg tiag tiag siv cov vijtsam loj-screen, yog li 18-pin ib-channel DVI interface yog qhov txaus. Rau qhov loj-screen LCD saib, 24-tus pin dual-channel DVI yog qhov yuav tsum muaj.
Raws li rau cov kev qhia tshwj xeeb ntawm 18+5 thiab 24+5, lawv txhua tus tau koom nrog DVI-I, thiab cov xaim ntxiv 4 siv tau kom haum rau cov qub VGA cov cim qhia. Qhov kev sib txuam zoo no feem ntau siv ntawm daim npav npav, cov zaub yeej tsis siv, tshwj tsis yog nws tsuas yog tib qho interface xws li 970P yuav raug txiav txim siab.
