Kombuta inoratidzira interface: DP, HDMI, DVI, VGA uye mamwe 4 marudzi enzvimbo.Ratidza tambo yekuita chinzvimbo: DP> HDMI> DVI> VGA.Pakati pavo, VGA chiratidzo cheanalog, icho chinobviswa neiyo mainstream interface ikozvino.DVI, HDMI, uye DP ese masaini edhijitari, ari iwo aripo mainstream interface.
1. Tft Lcd Screen RGB interface
(1) Tsanangudzo yeinterface
Tft Ratidza RGB ruvara chiyero chemavara muindasitiri.Inowanikwa nekushandura matatu mavara machaneti tsvuku (R), girini (G), uye bhuruu (B) uye superimposing iwo mumwe nemumwe kuwana akasiyana mavara., RGB ndiyo ruvara runomiririra nzira nhatu dzetsvuku, girini, uye bhuruu.Muyero uyu unosanganisira anenge mavara ese anogona kuonekwa nemunhu.Ndiyo imwe yeanonyanya kushandiswa mavara maitiro panguva ino.
Tft Ratidza VGA chiratidzo uye RGB chiratidzo
Lcd Screen RGB: Nzira dzekukodha ruvara dzinonzi "ruvara nzvimbo" kana "gamut".Mumashoko akareruka, "ruvara nzvimbo" chero ruvara munyika inogona kutsanangurwa senhamba yakatarwa kana shanduko.RGB (tsvuku, girini, bhuruu) ingori imwe yenzvimbo dzakawanda dzemavara.Neiyi encoding nzira, rumwe ruvara runogona kumiririrwa neatatu akasiyana - kusimba kwetsvuku, girini, uye bhuruu.Lcd Ratidza RGB ndiyo inonyanya kurongwa kana uchirekodha uye uchiratidza mavara emifananidzo.
Kuumbwa kweLcd Display VGA chiratidzo chakakamurwa kuita mhando shanu: RGBHV, ari iwo matatu ekutanga mavara ered, girinhi uye bhuruu, uye mutsara nemunda masaini masaini.Iyo Lcd Screen VGA yekufambisa kureba ipfupi kwazvo.Kuti vatumire chinhambwe chakareba muinjiniya chaihwo, vanhu vanobvisa tambo yeLcd Display VGA, vopatsanura masaini mashanu eRGBHV, voaendesa netambo shanu dzecoaxial.Iyi nzira yekufambisa inonzi Lcd Display RGB kutapurirana.Ichivanhu Chiratidzo ichi chinonziwo Lcd Screen RGB chiratidzo.
Mune mamwe mazwi, hapana mutsauko pakati peRGB neVGA.
Mazhinji makomputa nemidziyo yekunze yekuratidzira yakabatana kuburikidza neanalog Lcd Screen VGA interface, uye iyo yemifananidzo yekuratidzira ruzivo inogadzirwa nedigital mukati mekombuta inoshandurwa kuita R, G, B matatu ekutanga mavara masaini uye mutsara uye munda nedhijitari/analog inoshandura mu Graphics kadhi.Synchronous chiratidzo, chiratidzo chinotumirwa kune chiratidziro chishandiso kuburikidza netambo.Kune analog dhizaini yekuratidzira, senge analog CRT monitors, iyo siginecha inotumirwa zvakananga kune inoenderana kugadzirisa wedunhu kutyaira uye kudzora pikicha chubhu kugadzira mifananidzo.Kune madhijitari anoratidza madivayiri akadai seLCD neDLP, inowirirana A/D (analog/digital) inoshandura inoda kugadzirwa mumudziyo wekuratidzira kushandura chiratidzo cheanalogi kuita chiratidzo chedhijitari.Mushure mekushandura D/A neA/D2, mamwe mapikicha anorasika.
Naizvozvo, mhando yemufananidzo wemudziyo wekuratidzira uchishandisa Lcd Display DVI interface iri nani.Iyo kadhi yemifananidzo inowanzo shandisa DVD-I interface, kuitira kuti igone kubatana kune yakajairwa Lcd Display VGA interface kuburikidza neadapter.Monitor ine DVI interface inowanzo shandisa DVI-D interface.

Ndeapi mana akajairika maratidziro emakombuta monitors: VGA, DVI, HDMI, uye DP interfaces?
Dzimwe shamwari dzinowanzonetseka pamusoro pekuti ndeipi interface ndiyo yakanakisisa yekombiyuta yekucherechedza, kana tambo yedata inoshandiswa nekutarisa kwangu ndiyo yakanakisisa, ingave inotsigira yakakwirira-tsanangudzo, nezvimwewo. Kutaura zvazviri, tambo yedata haisi iyo inonyanya kukosha, kwenguva yakareba. sezvo komputa yako mamaboard/giraidhi kadhi uye yekutarisa kuuya nayo, yakakodzera uye haina kukanganisa ruzivo rwako.Kana iri iyo interface yekuratidzira iri nani, ndiyo poindi.
Parizvino, kupindirana kwakajairwa kwemakomputa monitors anonyanya kusanganisira DP, HDMI, DVI, uye VGA.Ratidza tambo yekuita chinzvimbo: DP> HDMI> DVI> VGA.Pakati pavo, VGA chiratidzo cheanalog, icho chinobviswa neiyo mainstream interface ikozvino.DVI, HDMI, uye DP ese masaini edhijitari, ari iwo aripo mainstream interface.
VGA interface
VGA (Vhidhiyo Graphics Array) chiyero chekutumira mavhidhiyo chakaunzwa neBMM pamwe chete nePS/2 muchina muna 1987. Iine zvakanakira kugadziriswa kwepamusoro, kukurumidza kuratidza kukurumidza uye mavara akapfuma, uye yakashandiswa zvakanyanya mumunda wekuratidzira kwemavara.Inotsigira kupisa plugging, asi haitsigire kutapurirana odhiyo.
Iyo VGA interface ndiyo inonyanya kuzivikanwa, inova mhando iyo yedu yakajairika komputa monitors yakabatana kune inotambira komputa.VGA interface ndeye D-mhando interface ine 15 pini muhuwandu, yakakamurwa kuita mitsara mitatu, mashanu mumutsara wega wega.Uye iyo VGA interface ine kuwedzera kwakasimba uye inogona kushandurwa nyore neiyo DVI interface.Iko kuiswa kweVGA interface kunotevera:
DVI interface
digital vhidhiyo interface
DVI ndeyepamusoro-tsanangudzo interface, asi isina odhiyo, kureva kuti, iyo DVI vhidhiyo tambo inongoendesa masaini emifananidzo masaini, asi haifambisi masaini masaini.Iyo interface chimiro inoratidzwa pazasi:
DVI interface ine 3 mhando uye 5 zvakatemwa, uye iyo terminal interface saizi i39.5mm×15.13mm.Mhando nhatu idzi dzinosanganisira DVI-A, DVI-D uye DVI-I interface mafomu.
DVI-D inongova nedhijitari interface, uye DVI-I ine ese ari maviri edhijitari uye analog interfaces.Parizvino, DVI-D ndiyo inonyanya kushandiswa.Panguva imwecheteyo, DVI-D uye DVI-Ini ndine imwe-channel (Single Link) uye mbiri-chiteshi (Dual Link).Kazhinji, izvo zvatinowanzoona ndeye-single-channel vhezheni, uye mutengo weiyo mbiri-chaneli vhezheni yakakwira zvakanyanya, saka mimwe michina yehunyanzvi chete iripo, uye zvakaoma kune vatengiwo zvavo kuti vazvione.DVI-A ndeye analog transmission standard, iyo inowanzoonekwa mune yakakura-screen nyanzvi CRTs.Nekudaro, nekuti haina mutsauko wakakosha kubva kuVGA uye kuita kwayo hakuna kukwirira, DVI-A yakasiiwa.
HDMI interface
HDMI
HDMI inogona kufambisa ese ari maviri akakwirira-tsanangudzo magiraidhi uye masaini masaini.Kazhinji kutaura, TV yakabatana nemba, uye ine anti-kupindira kwakasimba.Zvakakodzera kutaura kuti iyo interface yeazvino mota system, senge kufamba kwemotokari, zvakare HDMI.
Zvakanakira zveHDMI interface HDMI haingogone kusangana nekugadziriswa kwe1080P, asiwo inotsigira mafomati edhijitari akadai seDVD Audio, uye inotsigira masere-channel 96kHz kana stereo 192kHz digital audio transmission.
HDMI inotsigira EDID neDDC2B, saka zvishandiso zvine HDMI zvine hunhu hwe "plug uye tamba".Iyo siginecha sosi uye mudziyo wekuratidzira unongo "taurirana" uye otomatiki sarudza yakanyatsokodzera vhidhiyo / odhiyo fomati.
DP interface
HD dhijitari inoratidzira interface
DisplayPort zvakare yakakwira-tsananguro yedhijitari inoratidzira interface standard, inogona kubatana nekombuta uye cheki, kana komputa uye imba yemitambo.DisplayPort yakahwina rutsigiro rwemaindasitiri hofori akadai se AMD, Intel, NVIDIA, Dell, HP, Philips, Samsung, nezvimwewo, uye ndeye mahara kushandisa.
Kune marudzi maviri eDisplayPort ekunze anobatanidza: imwe ndiyo mhando yemhando, yakafanana ne USB, HDMI uye mamwe ma-connectors;imwe yacho imhando yemhando yakaderera, zvakanyanya kune maapplication ane mashoma ekubatanidza nzvimbo, seakanyanya-tete-notibook makomputa.
Iyo DP interface inogona kunzwisiswa seyakagadziridzwa vhezheni yeHDMI, iyo ine simba zvakanyanya mukuteerera uye vhidhiyo kutapurirana.
