Ukubonakala komugqa oqondile kumqapha kuyinkinga evamile. Ukuvusa kungahle kube yizizathu ezihlukile ezingatholakala uma wenza ukuphathwa okuthile. Cabanga ngombala we-strip, okungaba omnyama, omhlophe noma umbala.
Kungani imivimbo eqondile ivela kusikrini sokuqapha?
Ukuze uthole isithombe, i-chip eqondile iyadingeka ekubonisweni, ebeka eceleni ngokwekhadi levidyo noma ehlanganiswe kumprosesa ophakathi. Ukwaziswa okuvela kuwo ngokusebenzisa i-loop kuyadluliselwa esibukweni, futhi i-motherboard ilawula uhlelo. Ukuqhubekela phambili kulokhu, kungenzeka ukuhlukanisa izizathu zokuthi kungani imigqa emibala ivela kumqapha:
- Ngokuvamile inkinga ikhona ukungasebenzi kwebhodi le-motherboard, ngoba le ngxenye cishe ayitholakali umonakalo. Ibhodi ayiphumelelwanga kaningi ngenxa yomshado okhona, ngemuva kwesigamu esifushane, ukuqhutshwa kwamandla futhi ngenxa yezinye izinkinga. Ngaphezu kwalokho, kufanele kuqashelwe ukuthi ngokuhluleka kwebhodi le-motherboard, ama-bands kuphela ayaboniswa kabili, njengoba kunamaphuzu amanye.
- Uma ama-strips ebonakalayo avela kumqapha, ngokuvamile isizathu sisekhadini levidiyo, ukuphazamiseka kwalo okuhlotshaniswa nokuchithwa kwe chip ngenxa yokushisa.
- Ukuze uthumele izithombe kuma-laptops, i-loop noma ikhebula elixhunywe ebhodini le-motherboard kanye nokuboniswa lisetshenzisiwe. Uma le ngxenye ikhonjiwe noma ibonakele, ama-band avela kumqapha.
- Isizathu esivame kakhulu sibhekene nokuhluleka kwe-matrix. Kumele kukhunjulwe ukuthi isikrini esiphethini se-laptop sinzima kakhulu futhi uma idivaysi inesihluthulelo, ungalimaza i-matrix.
- Ngokuvamile, kodwa kungenzeka ukuthi ama-bands avele kumsindisi ngenxa yabashayeli, ngakho-ke into yokuqala okufanele uyenze lapho kuqhutshwa amaphuzu ukubuyisela "izinkuni".
I-pink band eqondile ekuqapha
Ezimweni eziningi, imivimbo eminingi enemibala esikrinini inokuxhumana nokuhlukana kwe-matrix yesimangalo. Lokhu kungenziwa ngenxa yokuhluleka ohlelweni lokunikezwa kwamandla, ukuwa, ukushaqeka kanye neminye impikiswano efanayo noma ukugqoka izingxenye. Uma kukhona ibhande eliqondile kumqapha, elidwetshwe nge-pink noma elibomvu, lokhu ngokuvamile kubonisa iphutha nge-scanner. Ukubonakala kwesici esinjalo kungabonwa kumaqaphi amasha, futhi konke kusemshadweni wefektri.
Ibha elimhlophe elimhlophe ekuqapha
Okumhlophe, njenganoma imuphi omunye umbala wezintambo, kaningi kubonisa izinkinga emsebenzini we-matrix. Uma, ngokucindezela okuncane noma amanye amathonya kule ngxenye, ukuphazamiseka kuyanyamalala futhi kuvela futhi, lokhu kubonisa isidingo sokususa ingxenye, ngoba sehlulekile kakade. Uma imigoqo ebonakalayo ivela esikrinini sokuqapha ikhompyutha, engabonakali futhi ibonakala, khona-ke lokhu kungabangwa ukungasebenzi kwecingo le-VGA noma isihlungi sezinhlamvu ezihlinzeka ngokuqapha.
Imigoqo eluhlaza okwesibhakabhaka ekuqapha
Abasebenzisi abaningi ngemuva komdlalo omude, lapho inqubo ishaya, noma ikhadi levidiyo lisebenza ukugqoka, phawula ukuthi kwesikrini sokuqapha kubonakala amaqembu ahlaza okwesibhakabhaka. Kulesi simo, uma iwaranti isala, ikhadi levidiyo kufanele lishintshwe. Kunesinye isizathu sokubonakala kwemicu eluhlaza okwesibhakabhaka noma eluhlaza okwesibhakabhaka - umonakalo okwenziwe kumunye oxhumana nabo be-matrix loop noma isitoreji se-video solder amabhola kusukela ku-BGA substrate ngenxa yokushisa.
Ibha ephuzi elimhlophe ekuqapha
Ukunquma imbangela yokwehluleka, udinga ukwenza okunye ukukhwabanisa. Uma umugqa oqondile uvela kumqapha we-LCD, bese uyinqamula ku-unit unit bese uyixhuma kwinethiwekhi. Uma ngabe leli bhanti liphela, kunezinkinga ekusebenzeni kwekhadi levidyo, ngakho-ke kuyadingeka ukuhlola uhlelo lokupholisa bese ufaka abashayeli abasha. Uma izibopho zishiywe, khona-ke iphutha lihlobene nokuboniswa. Uma umbala obala wombala ophuzi noma omunye umthunzi uvela kumqapha, kufanele ubone ukuthi kunamaphi amakhondomu ekhadini levidiyo bese uyabatshintsha.
Ibhande elibomvu elilindile kusikrini sokuqapha
Kukhona abasebenzisi abakhononda ukuthi kukhona ukuphazamiseka ngezikhathi esibukweni. Uma uzibuza ukuthi kungani imivimbo ebomvu ivela kumqapha, kufanelekile ukwazi ukuthi ngokuvamile kuvame ukuxhumana okungalungile kwe-matrix loop. Ngokuvamile, inkinga ingabangelwa ukushisa kwezici. Izindawo zokuma kwe-rectangular, ezakhiwe ngama-vertical bands - isignali mayelana nokuthutha noma ukulimala kuzixhumi zokuxhumana kwekhebula. Ezinye izizathu: kwakukhona inqola yethrekhi ebhodini lokulawula noma ikhebula lokulawula ividiyo elimele noma ucingo lwe-VGA.
Ibha elimnyama elilindile ekuqapha
Ngokwezibuyekezo ezikrinini ngezinye izikhathi kubonakala imigoqo emnyama, engatholakala ezindaweni ezihlukene ngisho naphakathi. Ibha elincane elibonakalayo eliqaphayo livela uma kukhona ukwehluleka noma ukuphazamiseka ekusebenzeni kwekhadi levidiyo, i-matrix noma i-loop yayo. Uma kunqunywe ukuthi yonke into iyiphutha ematrix, khona-ke inkinga ngeke ilungiswe futhi isixazululo kuphela ukubuyisela ingxenye.
Ama-vertical bands avele esitokisini - ukuthi benzeni?
Izenzo zokuthola izibopho zizohambelana ngokuqondile nesizathu esibangela ukwehluleka:
- Okokuqala, sizokwazi ukuthi singasusa kanjani ibha yokumaka ekuqapha uma ikhadi levidiyo lingalungile. Okokuqala, hlola ikhwalithi yesistimu yokupholisa, isibonelo, sebenzisa uhlelo olukhethekile olwenza izinga lokushisa. Hlukanisa ikhomputha bese ususa uthuli oluqoqiwe uphinde ufake esikhundleni samafutha ashisayo. Kuma laptops, sebenzisa ukuma nabalandeli abengeziwe.
- Uma inkinga kwenzeka ngenxa ye-motherboard noma ikhebula elingalungile, kungcono ukuthi ungazami futhi ungazami ukulungisa ukwehluleka ngokwakho, ukuze ungabonakali isimo, ngakho-ke thatha ukuqapha noma ikhompyutha ukuze ixilongwe esikhungweni senkonzo.
