1. Tft Lcd Screen RGB interface
(1) Ingcaciso yesinxibelelanisi
Tft Bonisa umbala we-RGB ngumgangatho wombala kumashishini.Ifunyaniswa ngokutshintsha imijelo emithathu yemibala ebomvu (R), eluhlaza (G), kunye nebhlowu (B) kwaye igqithise enye kwenye ukuze ifumane imibala eyahlukeneyo., i-RGB ngumbala omele amajelo amathathu obomvu, oluhlaza, nobhlowu.Lo mgangatho uquka phantse yonke imibala enokubonwa ngumbono womntu.Yenye yeenkqubo zemibala ezisetyenziswa kakhulu ngoku.
Tft Bonisa uphawu lweVGA kunye nomqondiso weRGB
I-Lcd Screen RGB: Iindlela zokufaka ikhowudi yombala ngokudibeneyo zibizwa ngokuba "yindawo yombala" okanye "i-gamut".Ngemigaqo elula, "indawo yombala" yanoma yimuphi umbala emhlabeni inokuchazwa njengenani eliqingqiweyo okanye eliguquguqukayo.I-RGB (ebomvu, eluhlaza, eluhlaza okwesibhakabhaka) yenye yeendawo ezininzi zemibala.Ngale ndlela yokufaka ikhowudi, umbala ngamnye unokumelwa ngezinto ezintathu eziguquguqukayo - ubunzulu bobomvu, obuluhlaza, obuluhlaza.I-Lcd Display RGB yeyona nkqubo ixhaphakileyo xa urekhoda kwaye ubonisa imifanekiso yemibala.
Ukubunjwa kwe-Lcd Bonisa isignali ye-VGA ihlukaniswe kwiintlobo ezintlanu: i-RGBHV, eyimibala emithathu ephambili ebomvu, eluhlaza kunye nohlaza okwesibhakabhaka, kunye neempawu zokuvumelanisa umgca kunye nentsimi.Umgama wothumelo we-Lcd Screen VGA mfutshane kakhulu.Ukuze udlulise umgama omde kubunjineli bokwenyani, abantu baqhawula intambo ye-Lcd Display VGA, bahlule imiqondiso emihlanu ye-RGBHV, kwaye bayisasaze ngeentambo ezintlanu ze-coaxial.Le ndlela yosasazo ibizwa ngokuba yi-Lcd Display RGB transmission.Kungokwesiko Lo mqondiso ukwabizwa ngokuba ngumqondiso weLcd Screen RGB.
Ngamanye amazwi, akukho mahluko phakathi kweRGB kunye neVGA.
Uninzi lweekhompyuter kunye nezixhobo zokubonisa zangaphandle ziqhagamshelwe nge-analog Lcd Screen VGA interface, kwaye ulwazi lomfanekiso wokuboniswa olwenziwa ngokwedijithali ngaphakathi kwikhompyuter luguqulwa lube yi-R, G, B imiqondiso emithathu yemibala ephambili kunye nomgca kunye nentsimi yi-digital / analog converter kwi ikhadi lemizobo.Isiginali yongqamaniso, isiginali igqithiselwa kwisixhobo sokubonisa ngentambo.Kwizixhobo zokubonisa i-analog, ezifana ne-analog monitors ye-CRT, isibonakaliso sithunyelwa ngokuthe ngqo kwisekethe yokucubungula ehambelanayo ukuqhuba nokulawula ityhubhu yesithombe ukuvelisa imifanekiso.Kwizixhobo zokubonisa idijithali ezifana ne-LCD kunye ne-DLP, i-converter ehambelanayo ye-A / D (i-analog/digital) kufuneka iqwalaselwe kwisixhobo sokubonisa ukuguqula isignali ye-analog ibe ngumqondiso wedijithali.Emva kokuguqulwa kwe-D/A kunye ne-A/D2, ezinye iinkcukacha zomfanekiso zilahlekile ngokungenakuthintelwa.
Ke ngoko, umgangatho womfanekiso wesixhobo sokubonisa usebenzisa ujongano lwe-Lcd Display DVI ungcono.Ikhadi lemizobo lisebenzisa ujongano lweDVD-I, ukuze ludityaniswe kujongano oluqhelekileyo lweLcd Bonisa VGA ngeadaptha.Imonitha enojongano lweDVI ngokuqhelekileyo isebenzisa ujongano lweDVI-D.

Zeziphi iindlela ezi-4 eziqhelekileyo zojongano lwecomputer: VGA, DVI, HDMI, kunye nojongano lweDP?
Abanye abahlobo bahlala bexhalabele malunga nokuba yeyiphi i-interface eyona ilungileyo kwi-monitor yekhompyutheni, nokuba intambo yedatha esetyenziswe ngumhloli wam yeyona nto ingcono, nokuba ixhasa i-high-definition, njl. Enyanisweni, intambo yedatha ayiyona ibalulekileyo, nje njengoko ikhompyuter yakho i-motherboard / ikhadi lemizobo kunye nokubeka iliso kuza nayo, ifanelekile kwaye ayichaphazeli amava akho.Ngokuphathelele ukuba yeyiphi imbonakalo yojongano olungcono, nantso ingongoma.
Okwangoku, ujongano oluqhelekileyo lwabahloli bekhompyuter ikakhulu lubandakanya iDP, HDMI, DVI, kunye neVGA.Bonisa umgangatho wokusebenza kwentambo: DP>HDMI>DVI>VGA.Phakathi kwabo, i-VGA isignali ye-analog, ekhutshwe ngokusisiseko yi-interface engundoqo ngoku.I-DVI, i-HDMI, kunye ne-DP yizo zonke iimpawu zedijithali, ezona ndawo zikhoyo ngoku.
Ujongano lweVGA
I-VGA (i-Video Graphics Array) ngumgangatho wokuhanjiswa kwevidiyo owenziwe yi-IBM kunye nomshini we-PS / 2 ngo-1987. Ineenzuzo zesisombululo esiphezulu, isantya sokubonisa ngokukhawuleza kunye nemibala ecebileyo, kwaye isetyenziswe ngokubanzi kwibala lokubonisa imibala.Ixhasa iplagi eshushu, kodwa ayikuxhasi ukuhanjiswa kweaudio.
Ujongano lweVGA lolona luxhaphakileyo, luhlobo apho iimonitha zethu eziqhelekileyo zekhompyuter ziqhagamshelwe kwikhompyuter yenginginya.I-interface ye-VGA yi-interface yohlobo lwe-D enezikhonkwane ezili-15 zizonke, zahlulwe zibe yimiqolo emithathu, emihlanu kumqolo ngamnye.Kwaye ujongano lweVGA lunokwandiswa olomeleleyo kwaye lunokuguqulwa ngokulula kunye nojongano lweDVI.Ukuqaliswa kojongano lweVGA ngolu hlobo lulandelayo:
Ujongano lweDVI
ujongano lwevidiyo yedijithali
I-DVI lujongano oluphezulu, kodwa ngaphandle komsindo, oko kukuthi, intambo yevidiyo ye-DVI ihambisa kuphela imiqondiso yemifanekiso yemifanekiso, kodwa ayihambisi imiqondiso yomsindo.Ubume bojongano njengoko kubonisiwe ngezantsi:
I-interface ye-DVI ineentlobo ezi-3 kunye neenkcukacha ezi-5, kwaye ubukhulu be-terminal interface yi-39.5mm × 15.13mm.Ezi ntlobo zintathu ziquka i-DVI-A, i-DVI-D kunye neefom ze-interface ye-DVI-I.
I-DVI-D ine-interface yedijithali kuphela, kwaye i-DVI-I ine-interfaces yedijithali kunye ne-analog.Okwangoku, i-DVI-D sesona sicelo siphambili.Ngexesha elifanayo, i-DVI-D kunye ne-DVI-I-Channel enye (i-Single Link) kunye ne-channel-channel (i-Dual Link).Ngokubanzi, into esiqhele ukuyibona yinguqulelo yetshaneli enye, kwaye iindleko zenguqulelo ye-double-channel ziphezulu kakhulu, ngoko ke zizixhobo ezithile zobuchwephesha ezifumanekayo, kwaye kunzima kubathengi abaqhelekileyo ukuyibona.I-DVI-A ngumgangatho wothumelo lwe-analog, enokuthi ibonakale rhoqo kwii-CRT zobuchule zesikrini esikhulu.Nangona kunjalo, ngenxa yokuba ayinamahluko ubalulekileyo kwi-VGA kwaye ukusebenza kwayo akukho phezulu, i-DVI-A iye yashiywa.
Ujongano lweHDMI
HDMI
I-HDMI inokudlulisa zombini iigraphics eziphezulu kunye neempawu zomsindo.Ngokuqhelekileyo, iTV iqhagamshelwe kwikhaya, kwaye inamandla okuthintela ukuphazamiseka.Kuyafaneleka ukukhankanya ukuba i-interface yenkqubo yesithuthi yangoku, njengokuhamba kwesithuthi, nayo i-HDMI.
Izibonelelo ze-HDMI i-HDMI i-HDMI ayikwazi ukuhlangabezana nesisombululo se-1080P kuphela, kodwa iphinde ixhase iifomathi zomsindo wedijithali ezifana ne-DVD Audio, kunye nenkxaso ye-8-channel 96kHz okanye i-stereo 192kHz yokuhanjiswa komsindo wedijithali.
I-HDMI ixhasa i-EDID kunye ne-DDC2B, ngoko ke izixhobo ezine-HDMI zineempawu "zeplagi kunye nokudlala".Umthombo wesiginali kunye nesixhobo sokubonisa siya "kuthethathethana" ngokuzenzekelayo kwaye ukhethe ngokuzenzekelayo eyona ifomathi ifanelekileyo yevidiyo/yomsindo.
Ujongano lweDP
Ujongano lwedijithali lweHD
I-DisplayPort ibuye ibe yinkcazo ephezulu yomgangatho wokubonisa idijithali, enokuthi idibaniswe nekhompyutheni kunye ne-monitor, okanye kwikhompyutheni kunye nekhaya lethiyetha.I-DisplayPort iphumelele inkxaso yee-giants zoshishino ezifana ne-AMD, i-Intel, i-NVIDIA, i-Dell, i-HP, i-Philips, i-Samsung, njl., kwaye ikhululekile ukuyisebenzisa.
Kukho iintlobo ezimbini zeDisplayPort izixhumi zangaphandle: enye luhlobo oluqhelekileyo, olufana ne-USB, i-HDMI kunye nezinye izixhumi;enye luhlobo lweprofayile ephantsi, ikakhulu kwizicelo ezinodibaniso olulinganiselweyo lwendawo, njengeekhompyuter ezibhityileyo kakhulu.
I-interface ye-DP inokuqondwa njengenguqu ephuculweyo ye-HDMI, enamandla ngakumbi kwi-audio kunye nevidiyo yokuhanjiswa.
Ixesha lokuposa: Sep-06-2023
