Isikrini seLCD sisixhobo sokubonisa esihlala sidibana naso kubomi bethu bemihla ngemihla.Isetyenziswa ngokubanzi kwizixhobo zombane ezahlukeneyo ezifana ne-Intanethi yeZinto, ubukrelekrele bokwenziwa, ukhathalelo lwezonyango, ikhaya elilumkileyo, ulawulo lwamashishini, kunye nokhuseleko kwiimveliso zombane.Eli nqaku liza kwazisa ulwazi olufanelekileyo loMboniso weLcd, kubandakanywa imigaqo yokusebenza, iimpawu, ukuhlelwa kunye nokusetyenziswa, kunye nokubonelela ngeengcebiso zokukhetha kunye nokuthenga izikrini ze-LCD.
I-LCD, igama elipheleleyo leLiquid Crystal Display (LCD), yitekhnoloji elawula ulungelelwaniso lweeathom zekristale zangoku ukuze zibone umboniso womfanekiso.Iimolekyuli zekristale zolwelo ziikhompawundi ezikhethekileyo zezinto eziphilayo ezinobume phakathi kokuqinileyo kunye nolwelo.Kwimeko eqhelekileyo, iimolekyuli zekristale zamanzi zicwangciswe ngendlela ehlelekile, kwaye imifanekiso ayinakuboniswa.Xa ikhoyo ngoku idlula kwiscreen, iimolekyuli zekristale zolwelo ziya kujikwa, ngaloo ndlela zitshintshe ilungiselelo labo, kwaye emva koko zitshintshe ukuhanjiswa kokukhanya, ngaloo ndlela zivelise imifanekiso ebonakalayo.Le yindlela izikrini zeLCD ezisebenza ngayo.
Umboniso wekristale we-lcd uneempawu ezininzi ezenza enye yezona teknoloji zisetyenziswa kakhulu.Okokuqala, inokusetyenziswa kwamandla aphantsi.Kuba iimolekyuli zekristale elulwelo zitshintsha kuphela xa umsinga wombane udlula kuzo, isiboniso sekristale seLCD sisebenzisa amandla amancinci kunobunye ubugcisa bokubonisa.Okwesibini, izikrini ze-LCD zinokukhanya okuphezulu kunye nokuchasana.Ngenxa yeepropati ze-crystal molecules zamanzi, i-LCD i-crystal display inokuvelisa imibala ecacileyo kunye nemifanekiso ecacileyo.Ukongeza, i-Lcd Display ine-angle enkulu yokujonga, ukwenzela ukuba imifanekiso yokujonga ingakhawulwanga yi-angle.Ekugqibeleni, umboniso we-crystal LCD unesantya sokuphendula ngokukhawuleza kwaye unokubonisa imifanekiso eguqukayo yesantya esiphezulu, esifanelekileyo ukubukela iifilimu kunye nokudlala imidlalo.
Ngokweemfuno ezahlukeneyo zesicelo, izikrini ze-LCD zinokwahlulwa zibe ziindidi ezininzi.Olona hlobo luxhaphakileyo yi-TFT-Lcd Display (Thin-Film Transistor Liquid Crystal Display).Izikrini ze-TFT-LCD zilawula iimolekyuli zekristale zolwelo ngokusebenzisa iitransistors zefilimu ezibhityileyo, ezinoxinano oluphezulu lwepixel kunye nomgangatho womfanekiso ongcono.Ukongezelela, kukho i-TN-Ips Lcd (i-Twisted Nematic Liquid Crystal Display), i-IPS-Lcd Display (In-Plane Switching Liquid Crystal Display), izikrini ze-VA-LCD (i-Vertical Alignment Liquid Crystal Display) kunye nezinye iintlobo ezahlukeneyo ze-LCD izikrini.Uhlobo ngalunye luneempawu zalo ezithile kunye neenkalo zesicelo.Ngokweemeko ezahlukeneyo zesicelo, umboniso we-LCD wekristale unokwahlulwa ngokwezikrini ze-LCD zeshishini, izikrini ze-LCD zemoto, kunye ne-Lcd yabathengi be-elektroniki.Ukukhetha uhlobo oluchanekileyo lwesikrini se-LCD kubalulekile ukuhlangabezana neemfuno zomntu ngamnye.
Xa ukhetha kwaye uthenga i-Ips Lcd, kukho izinto ezininzi ezibalulekileyo ekufuneka uziqwalasele.Eyokuqala yisayizi yesikrini.Isiboniso se-Lcd sifumaneka kwiisayizi ezahlukeneyo ezahlukeneyo, kwaye kuyafuneka ukukhetha ubungakanani obufanelekileyo ngokweemeko zosetyenziso kunye neemfuno.Umzekelo, ukuba uthenga iTV, kufuneka uqwalasele ubungakanani begumbi kunye nomgama wokubukela.Okwesibini sisisombululo.Isisombululo simisela ukucaca komfanekiso wesikrini.Isikrini esinesisombululo esiphezulu sinokubonisa iinkcukacha ezininzi, kodwa sonyusa iimfuno ze-hardware.Okwesithathu yireyithi yokuhlaziya.Izinga lokuhlaziya limisela ukugudiswa kwemifanekiso eboniswe kwisikrini, kwaye izinga eliphezulu lokuhlaziya linokubonelela ngemifanekiso ecacileyo kunye nelula.Ekugqibeleni kukho ujongano kunye neenketho zonxibelelwano.Ngokweemfuno zezixhobo ezisetyenzisiweyo, kuyimfuneko ukuba kuqinisekiswe ukuba isikrini se-LCD sinonxibelelwano olufanelekileyo kunye neendlela zokudibanisa ukudibanisa nezinye izixhobo.
Ukongeza kwezi zinto zisisiseko, kukho imisebenzi eyongezelelweyo kunye neempawu ezinokuqwalaselwa.Ngokomzekelo, ezinye i-Ips Lcd zineteknoloji ye-anti-glare yokunciphisa ukubonakaliswa kunye ne-glare kwiindawo ezikhanyayo.Kukwakho nezikrini ze-LCD ezinombala obanzi we-gamut kunye nezakhono ze-HDR zemifanekiso eyinyani kunye necacileyo.Ukongezelela, umsebenzi wesikrini sokuchukumisa uyimfuneko eqhelekileyo, enokuthi iqhutywe ngokufanelekileyo ngokuchukumisa.
Ngokubanzi, ukukhetha kunye nokuthenga isikrini se-LCD kufuna uqwalaselo olubanzi lwezinto ezininzi.Iimeko ezahlukeneyo zesicelo kunye nezinto ozikhethayo zinokuba neemfuno ezahlukeneyo.Ukuqonda imigaqo, iimpawu kunye nokuhlelwa kwe-Ips Lcd kunokusinceda ukuba sikhethe ngcono iimveliso ezihambelana neemfuno zethu.Ngaphambi kokuthenga, kuyacetyiswa ukuba ufunde iinkcukacha zemveliso kunye nokuphononongwa komsebenzisi ukuqinisekisa ukuba ukhetha isikrini se-LCD esizinzileyo nesithembekileyo.
