Imigaragarire ya mudasobwa: DP, HDMI, DVI, VGA nubundi bwoko 4 bwimikorere. Erekana urutonde rwimikorere ya kabili: DP> HDMI> DVI> VGA. Muri byo, VGA ni ikimenyetso kigereranya, gikurwaho ahanini ninzira nyamukuru ubu. DVI, HDMI, na DP byose ni ibimenyetso bya digitale, aribyo bigezweho.
1. Tft Lcd Mugaragaza RGB Imigaragarire
(1) Ibisobanuro
Tft Erekana ibara rya RGB ni ibara risanzwe mu nganda. Iraboneka muguhindura imiyoboro itatu yamabara yumutuku (R), icyatsi (G), nubururu (B) hanyuma ukayishyira hamwe kugirango ubone amabara atandukanye. , RGB ni ibara ryerekana imiyoboro itatu yumutuku, icyatsi, nubururu. Ibipimo bikubiyemo amabara hafi ya yose iyerekwa ryabantu rishobora kubona. Nimwe muma sisitemu akoreshwa cyane muri iki gihe.
Tft Erekana ikimenyetso cya VGA n'ikimenyetso cya RGB
Lcd Mugaragaza RGB: Uburyo bwo gushushanya ibara hamwe hamwe bita "umwanya wamabara" cyangwa "gamut". Mu magambo yoroshye, "umwanya wibara" ryamabara yose kwisi arashobora gusobanurwa nkumubare uhamye cyangwa uhinduka. RGB (umutuku, icyatsi, ubururu) nimwe gusa mumwanya wamabara. Hamwe nubu buryo bwa kodegisi, buri bara rishobora kugaragazwa nimpinduka eshatu - ubukana bwumutuku, icyatsi, nubururu. Lcd Erekana RGB nigikorwa gikunze kugaragara iyo gufata amajwi no kwerekana amashusho yamabara.
Ibigize ibimenyetso bya Lcd Erekana ibimenyetso VGA bigabanijwemo ubwoko butanu: RGBHV, ayo akaba ari amabara atatu yibanze yumutuku, icyatsi nubururu, numurongo hamwe nibimenyetso byo guhuza umurima. Lcd Mugaragaza VGA yoherejwe ni ngufi cyane. Kugirango wohereze intera ndende mubuhanga nyabwo, abantu basenya umugozi wa Lcd Erekana VGA, batandukanya ibimenyetso bitanu bya RGBHV, hanyuma babyohereza hamwe ninsinga eshanu za coaxial. Ubu buryo bwo kohereza bwitwa Lcd Erekana RGB yohereza. Biramenyerewe Iki kimenyetso nacyo cyitwa Lcd Mugaragaza RGB ikimenyetso.
Muyandi magambo, mubyukuri nta tandukaniro riri hagati ya RGB na VGA.
Mudasobwa nyinshi hamwe nibikoresho byerekana hanze byahujwe binyuze mumashusho ya Lcd Mugaragaza ya VGA, kandi amakuru yerekana amashusho yakozwe muburyo bwa digitale imbere muri mudasobwa ahindurwamo R, G, B ibimenyetso bitatu byamabara yibanze n'umurongo n'umurima hamwe na digitale / analog ihindura muri ikarita. Ikimenyetso cya syncronous, ikimenyetso cyoherezwa mubikoresho byerekana binyuze mumurongo. Kubikoresho byerekana analogi, nka monitor ya CRT igereranya, ibimenyetso byoherejwe muburyo butaziguye kugirango bikore kandi bigenzure umuyoboro wamashusho kugirango ubyare amashusho. Kubikoresho byerekana ibyuma nka LCD na DLP, bihindura A / D (analog / digital) bihindura bigomba gushyirwaho mubikoresho byerekana kugirango bihindure ibimenyetso bisa mubimenyetso bya digitale. Nyuma ya D / A na A / D2, ibisobanuro bimwe byamashusho byanze bikunze byatakaye.
Kubwibyo, ubwiza bwibishusho bwibikoresho byerekana ukoresheje Lcd Yerekana DVI interineti nibyiza. Ikarita ishushanya muri rusange ikoresha interineti ya DVD-I, kugirango ishobore guhuzwa na Lcd Yerekana VGA isanzwe binyuze muri adapt. Monitor ifite interineti ya DVI muri rusange ikoresha interineti ya DVI-D.

Kurinda-Umuyoboro Mugari Kurinda Ibirimo
Ni ubuhe buryo 4 busanzwe bukurikirana mudasobwa: VGA, DVI, HDMI, na DP?
Inshuti zimwe zikunze guhangayikishwa ninteruro nziza kuri monitor ya mudasobwa, niba insinga yamakuru yakoreshejwe na monitor yanjye ari nziza, niba ishyigikira ibisobanuro bihanitse, nibindi. Mubyukuri, insinga yamakuru ntabwo aribyingenzi, nkigihe kirekire nka mudasobwa yububiko bwa mudasobwa / ikarita yubushushanyo hamwe na monitor ikazana nayo, irakwiriye kandi mubyukuri ntabwo ihindura uburambe bwawe. Kubijyanye no kwerekana interineti nibyiza, niyo ngingo.
Kugeza ubu, interineti isanzwe ya monitor ya mudasobwa harimo DP, HDMI, DVI, na VGA. Erekana urutonde rwimikorere ya kabili: DP> HDMI> DVI> VGA. Muri byo, VGA ni ikimenyetso kigereranya, gikurwaho ahanini ninzira nyamukuru ubu. DVI, HDMI, na DP byose ni ibimenyetso bya digitale, aribyo bigezweho.
Imigaragarire ya VGA
VGA. Gushyigikira gucomeka bishyushye, ariko ntibishyigikira kohereza amajwi.
Imigaragarire ya VGA niyo ikunze kugaragara, nubwoko busanzwe bwa mudasobwa yacu isanzwe ihujwe na mudasobwa yakira. Imigaragarire ya VGA ni D-Imigaragarire ya D ifite pin 15 zose hamwe, igabanijwemo imirongo itatu, itanu kuri buri murongo. Imigaragarire ya VGA ifite kwaguka gukomeye kandi irashobora guhinduka byoroshye hamwe na DVI. Intangiriro yimikorere ya VGA nuburyo bukurikira:
Imigaragarire ya DVI
Imigaragarire ya videwo
DVI ni interineti isobanura cyane, ariko idafite amajwi, ni ukuvuga, umugozi wa videwo ya DVI wohereza gusa ibimenyetso byerekana amashusho, ariko ntabwo wohereza ibimenyetso byamajwi. Imiterere yimbere ni nkuko bigaragara hano:
Imigaragarire ya DVI ifite ubwoko 3 nibisobanuro 5, naho ubunini bwa interineti ni 39.5mm × 15.13mm. Ubwoko butatu burimo DVI-A, DVI-D na DVI-I imiterere yimiterere.
DVI-D ifite gusa interineti ya digitale, na DVI-I ifite ibice byombi kandi bigereranya. Kuri ubu, DVI-D niyo porogaramu nyamukuru. Mugihe kimwe, DVI-D na DVI-I mfite umuyoboro umwe (Umuyoboro umwe) hamwe numuyoboro wa kabiri (Ihuza kabiri). Muri rusange, ibyo dusanzwe tubona ni umuyoboro umwe, kandi ikiguzi cya verisiyo ebyiri ni kinini cyane, bityo ibikoresho byumwuga gusa birahari, kandi biragoye kubakoresha bisanzwe kubibona. DVI-A ni ikigereranyo cyo kohereza, gishobora kugaragara muri ecran nini ya CRTs. Ariko, kubera ko ntaho itandukaniye na VGA kandi imikorere yayo ntabwo iri hejuru, DVI-A yaratereranye.
Imigaragarire ya HDMI
HDMI
HDMI irashobora kohereza ibishushanyo bisobanutse neza hamwe nibimenyetso byamajwi. Muri rusange, TV ihujwe murugo, kandi ifite anti-intervention ikomeye. Birakwiye ko tuvuga ko isura ya sisitemu yimodoka igezweho, nko kugendesha ibinyabiziga, nayo HDMI.
Ibyiza bya interineti ya HDMI HDMI ntishobora kubahiriza gusa imyanzuro ya 1080P, ariko kandi ishyigikira imiterere y amajwi ya digitale nka DVD Audio, kandi igashyigikira imiyoboro umunani 96kHz cyangwa stereo 192kHz yohereza amajwi.
HDMI ishyigikira EDID na DDC2B, bityo ibikoresho bifite HDMI bifite ibiranga "gucomeka no gukina". Inkomoko yikimenyetso nigikoresho cyo kwerekana bizahita "biganira" kandi bihita bihitamo imiterere ya videwo / amajwi.
Imigaragarire ya DP
Imigaragarire ya HD
DisplayPort nayo ni ibisobanuro bihanitse byerekana imibare yerekana interineti, ishobora guhuzwa na mudasobwa na monitor, cyangwa kuri mudasobwa hamwe n’ikinamico yo mu rugo. DisplayPort yatsindiye inkunga y'ibihangange mu nganda nka AMD, Intel, NVIDIA, Dell, HP, Philips, Samsung, n'ibindi, kandi ni ubuntu kubikoresha.
Hariho ubwoko bubiri bwa DisplayPort ihuza hanze: imwe nubwoko busanzwe, busa na USB, HDMI nabandi bahuza; ubundi ni ubwoko buke-bwihariye, cyane cyane kubisabwa bifite aho bihurira, nka mudasobwa ya ultra-thin.
Imigaragarire ya DP irashobora kumvikana nka verisiyo yongerewe ya HDMI, ikaba ikomeye cyane mu kohereza amajwi n'amashusho.
