Ukubonakala komgca wecala kweso sihlandlo esiqhelekileyo. Ukuvusa ingaba izizathu ezahlukeneyo ezinokuthi zifunyenwe ngokwenza ezinye izinto. Cinga umbala we-strip, onokuba ngumnyama, umhlophe okanye umbala.
Kutheni imivimbo ebonakalayo ivela kwi-screen yesikrini?
Ukufumana umfanekiso, i-graphic grap iyadingeka ekuboniseni, ebeka eceleni ngokwekhadi levidiyo okanye edibeneyo kwinkqubo ephambili. Ulwazi oluvela kuyo ngokusebenzisa i-loop ludluliselwa kwisikrini, kwaye i-motherboard ilawula inkqubo. Ukuqhubela phambili kule nto, kunokwenzeka ukuba ungabalulekanga izizathu zokuba kutheni imigca yokukhanya ibonakale kwi-esweni:
- Ngokuqhelekileyo le ngxaki ixhomekeke ekusebenziseni kakubi kwebhodi lebhodi, kuba le nxalenye ayinakuyingozi. Ibhodi ayikho myalelo ngokuphindaphindiweyo ngenxa yomtshato okhoyo, emva kwesiphaluka esifutshane, ukunyuka kwamandla kunye nezinye iingxaki. Ukongezelela, kufuneka kuqatshelwe ukuba ngokungaphumeleli kwebhodi lebhodi lemidiya, kuphela iimbambo ezingabonakaliyo, njengokuba kukho ezinye iintsilelo.
- Ukuba amaqhosha amacwecwe avela kweso siso, ngokuqhelekileyo isizathu esisekhadini levidiyo, ukuchithwa kwalo okuhambelana nokuchithwa kwe-chip ngenxa yokugqithisa.
- Ukudlulisa imifanekiso kwii-laptops, i-loop okanye ikhebula exhunywe kwibhodi ye-motherboard kunye nesiboniso isetyenzisiweyo. Ukuba le nxalenye icinyiwe okanye ibonakaliswe, amaqela avela kweso sondlo.
- Isizathu esona siqhelekileyo sichaphazela ukungaphumeleli kwe-matrix. Kufuneka ukhunjulwe ukuba isikrini kwi-laptop sibucayi kwaye xa isixhobo sikhulu, ungonakalisa i-matrix.
- Ngokuqhelekileyo, kodwa kunokwenzeka ukuba iifowuni zivele kwi-esweni ngenxa yabashayeli, ngoko ke into yokuqala yokuyenza xa iinqabana zenzeka khona ukubuyisela "imithi".
I-pink band ebonakalayo kwiso
Kwiimeko ezininzi, imivimbo enemibala emininzi kwiskrini inxulumene nokuphazamiseka kwe-matrix yesondlo. Oku kunokwenzeka ngenxa yesiphumo kwindlela yokubonelela ngamandla, ukuwa, ukutshitshiswa kunye nezinye iimpembelelo ezifanayo okanye ukugqithwa kwamalungu. Ukuba kukho iqela elimhlophe kweso siqendu, esicwetshwe ngepinki okanye ebomvu, ngoko oku kudla ngokubonisa iphoso nge-scanner. Ukubonakala kwesiphene esinjalo kungabonwa kwiindwendwe ezintsha, kwaye yonke into isemtshatweni wombane.
Ibha yomgca omhlophe kwi-esweni
Umhlophe, njengalowo nawuphi umbala weebhanti, ngokuqhelekileyo kubonisa iingxaki kumsebenzi we-matrix. Ukuba, ngokunyanzeliswa kancinci okanye ezinye iimpembelelo kule ngxenye, ukuphazamiseka kuyanyamalala kwaye kubonakala kwakhona, oku kubonisa isidingo sokutshintsha indawo, ekubeni sele iphumelele. Xa imivalo ebonakalayo ibonakala kwikhompyutheni yekhompyutheni, engabonakaliyo kwaye ibonakalise, oko kungakho ngenxa yokungahambi kakuhle kwefowuni yeVGA okanye iifayile ezixhasayo ezibonelela ngamehlo.
Iibhola eziluhlaza okwesibhakabhaka kweso saziso
Abasebenzisi abaninzi emva komdlalo omde, xa ubugcisa bugqithiseleyo, okanye ikhadi levidiyo lisebenza kwindwangu, phawula ukuba kwisesitmpileni kweso sikrini kubonakala iindidi eziluhlaza. Kule meko, ukuba iwaranti iyahlala, ikhadi levidiyo kufuneka ithathelwe endaweni. Kukho esinye isizathu sokuba kubonakale kwimibala eluhlaza okwesibhakabhaka okanye imivimbo eluhlaza okwesibhakabhaka - umonakalo owenzayo kumnye woxhumo lwe-matrix loop okanye uqokelelo lweebhola ze-video ze-barder ezivela kwi-BGA substrate ngenxa yokuphelisa.
Ibha yomthamo ophuzi kweso
Ukufumanisa isizathu sokungaphumeleli, kufuneka usebenze ngendlela ethile. Ukuba umgca wecala uvela kwi-LCD iqapha, ke unqanyulwe kwiyunithi yenkqubo uze uyixube kwinethiwekhi. Ukuba ngaba iqela liyabhubha, kukho iingxaki ekusebenzeni kwekhadi levidiyo, ngoko kuyimfuneko ukujonga inkqubo yokupholisa nokufaka abaqhubi abatsha. Ukuba iinqununu zishiywe, i-defect ihambelana nomboniso. Xa umgca wombala ophuzi okanye omnye umthunzi uvela kwi-esweni, kufuneka ubone ukuba kukho naziphi na izikhupheli kwikhadi levidiyo uze uzibeke endaweni.
Ibomvu ebomvu ebonakalayo kwiskrini yamehlo
Kukho abasebenzisi abakhalazayo ukuba kukho ukuphazamiseka ngezihlandlo kwesikrini. Ukuba uyazibuza ukuba kutheni imicu ebomvu ibonakala kweso sithuthi, oko kuyafaneleka ukuba wazi ukuba ngokuqhelekileyo konke okumalunga nobudlelwane obubi be-matrix loop. Ngokuqhelekileyo, ingxaki ibangelwa kukutsha kwezinto. Imimandla yombumba wengqungquthela, equlethwe ngamaqela angama-vertical-signal on the dustiness or damage to the connectors of the cable. Ezinye izizathu: kwakukho umgca womzila kwibhodi lokulawula okanye ikhebula lokulawula ividyo okanye i-VGA wire.
Ibha yomtshini omnyama kwi-esweni
Ngokutsho kokuphonononga kwesikrini ngamanye amaxesha kubonakala imivalo emnyama, enokufumaneka kwiindawo ezahlukeneyo nakwiziko. Ibha yomgca wecala kweso sithuthi ibonakala ukuba kukho ukungaphumeleli okanye ukuphazamiseka ekusebenzeni kwekhadi levidyo, matrix okanye i-loop yayo. Ukuba kwakumiselwe ukuba yonke into yintsebenziswano e-matrix, ngoko ingxaki ayiyi kuzinza kwaye isisombululo esisodwa sinokuyifaka indawo.
Amaqela afana nawo avela kwi-esweni - ntoni na?
Izenzo zokufumanisa iinqununu ziya kuhambelana ngqo nesizathu esibangela ukungaphumeleli:
- Okokuqala, siya kuqaphela indlela yokususa ibha yokumamela kweso sithuthi xa ikhadi levidiyo liphosakele. Okokuqala, jonga umgangatho wenkqubo yokupholisa, umzekelo, uqhuba inkqubo ekhethekileyo ebeka ubushushu. Hlukanisa ikhomputer kwaye ususe uthuli oluqokelelweyo uze ufake indawo yerhasi. Kwii-laptops, sebenzisa ukuma kunye nabalandeli abongezelelweyo.
- Ukuba le ngxaki ivela ngenxa yebhodi lebhodi le-motherboard okanye ikhebula, kungcono ukuba ungazami kwaye ungazami ukulungisa ukuhluleka ngokwakho, ukuze ungagxininisi imeko, ngoko thabatha iliso okanye ikhomputha ukuze uxilongwe kwiziko leenkonzo.
