I-Liquid Crystal Display (LCD) yinxalenye ebalulekileyo yefowuni ephathwayo edlala indima ebalulekileyo ekuboniseni imifanekiso kunye neetekisi.Yitekhnoloji esemva kwesikrini evumela abasebenzisi ukuba banxibelelane nezixhobo zabo ngokubonakalayo.
Izikrini ze-LCD ziqhele ukusetyenziswa kwiifowuni eziphathwayo ngenxa yokucaca kwazo okugqwesileyo, ukuveliswa kombala, kunye nokusebenza kakuhle kwamandla.Ezi zikrini zenziwe ngamaleko ahlukeneyo, kubandakanya isibane sangasemva, izihluzi zemibala, iimolekyuli zekristale yolwelo, kunye negridi ye-electrode ebonakalayo.
Umsebenzi ophambili weLCDkukulawula ukwakheka kwemifanekiso.Xa intlawulo yombane ifakwa kwisibonisi, iimolekyuli zekristale elulwelo ngaphakathi kwesikrini zilungelelanisa ukuvumela okanye ukuvala ukudlula kokukhanya.Le nkqubo imisela ukubonakala kweepikseli ezahlukeneyo, ekugqibeleni idala imifanekiso esiyibonayo.
Izikrini ze-LCD ezisetyenziswa kwiifowuni eziphathwayo ziza kwiindidi ezahlukeneyo, njenge-TN (i-Twisted Nematic) kunye ne-IPS (In-Plane Switching) izibonisi.Iziboniso ze-TN ziqhele ukufunyanwa kwiifowuni ezilungele uhlahlo lwabiwo-mali, ezinikezela ngamaxesha alungileyo okuphendula kunye namaxabiso afikelelekayo.Kwelinye icala, iziboniso ze-IPS zinokuchaneka kombala okuphezulu, ii-engile zokujonga ezibanzi, kunye nokusebenza okungcono ngokubanzi, okubenza babe lolona khetho lukhethwayo kwii-smartphones eziphezulu.
Izikrini ze-LCD zikwabonelela ngeenzuzo ezininzi kunezinye iintlobo zetekhnoloji yokubonisa.Enye yeenzuzo eziphambili kukusebenza kwabo kwamandla.I-LCDs zisebenzisa amandla amancinci xa kuthelekiswa nobuchwepheshe obudala bokuboniswa njenge-CRT (i-Cathode Ray Tube) yokubonisa.Oku kusebenza kakuhle kwamandla kuqinisekisa ubomi bebhetri obude kwiifowuni eziphathwayo, kuvumela abasebenzisi ukuba bahlale beqhagamshelwe ixesha elide ngaphandle kokukhathazeka ngokuphelelwa ngamandla.
Ukongeza,Izikrini ze-LCDzinika ukubonakala okugqwesileyo nakwindawo ezikhanyiswe ngokuqaqambileyo.Isici esikhanyayo se-LCD sikhanyisa isikrini, sivumela abasebenzisi ukuba babone umxholo ngokucacileyo naphantsi kwelanga elithe ngqo.Oku kwenza izikrini ze-LCD zifaneleke kakhulu ukusetyenziswa ngaphandle, ziphucula amava omsebenzisi.
Ngaphaya koko, itekhnoloji ye-LCD ivumela ukuveliswa kwezikrini ezincinci kunye nezikhaphukhaphu, zenza iiselfowuni zibekrwece kwaye zithwaleke.Ezi zixhobo zincinci kwaye zixineneyo zingena ngokukhululekileyo kwiipokotho kunye neebhegi, ziqinisekisa ukuba lula kubasebenzisi ekuhambeni.
Njengoko itekhnoloji ihambela phambili, izikrini zeLCD ziyaqhubeka nokuphucula ngokwemiqathango yesisombululo, ukuchaneka kombala, kunye nokukhanya.Uphando oluqhubekayo kunye neenzame zophuhliso zijolise ekuphuculeni amava abonakalayo kunye nokubonelela abasebenzisi ngezona mboniso zomgangatho ophezulu kwiifowuni zabo eziphathwayo.
Ukuqukumbela, i-LCD kwifowuni ephathwayo yitekhnoloji yesikrini enoxanduva lokubonisa ngokubonakalayo imifanekiso kunye neetekisi.Inika ukucaca, ukuveliswa kombala, ukusebenza kakuhle kwamandla, kunye nokubonakala okugqwesileyo nakwiindawo ezikhanyayo.Ngenkqubela phambili eqhubekayo, izikrini ze-LCD zinegalelo kuyilo oluthambileyo noluphathwayo lweeselfowuni zala maxesha, zinika abasebenzisi amava okubonwa awomeleziweyo.
