Isikrini se-LCD siyidivayisi yokubonisa esivame ukuhlangana nayo ekuphileni kwethu kwansuku zonke.Isetshenziswa kakhulu kumishini kagesi ehlukahlukene njenge-inthanethi Yezinto, ubuhlakani bokwenziwa, ukunakekelwa kwezokwelapha, ikhaya elihlakaniphile, ukulawula izimboni, kanye nokuphepha emikhiqizweni ye-elekthronikhi.Lesi sihloko sizokwethula ulwazi olufanele lwesibonisi se-Lcd, okuhlanganisa nezimiso zokusebenza, izici, ukuhlukaniswa nezinhlelo zokusebenza, futhi sinikeze iziphakamiso ezithile zokukhetha nokuthenga izikrini ze-LCD.
I-LCD, igama eligcwele i-Liquid Crystal Display (LCD), ubuchwepheshe obulawula ukuhlelwa kwama-molecule ekristalu ewuketshezi ngokwamanje ukuze kubonakale ukuboniswa kwesithombe.Ama-molecule e-liquid crystal ayinhlanganisela yemvelo ekhethekile enesimo phakathi kokuqinile noketshezi.Esimweni esivamile, ama-molecule e-crystal ewuketshezi ahlelwa ngendlela ehlelekile, futhi izithombe azikwazi ukuboniswa.Lapho okwamanje kudlula esikrinini, ama-molecule e-crystal ewuketshezi azosonteka, ngaleyo ndlela ashintshe ukuhlelwa kwawo, abese eshintsha ukudluliswa kokukhanya, ngaleyo ndlela akhiqize izithombe ezibonakalayo.Le yindlela izikrini ze-LCD ezisebenza ngayo.
Isibonisi sekristalu se-lcd sinezici eziningi ezizenza zibe obunye bobuchwepheshe bokubonisa obusetshenziswa kakhulu.Okokuqala, inokusetshenziswa kwamandla okuphansi.Ngenxa yokuthi ama-molecule e-liquid crystal ashintsha kuphela lapho amandla kagesi edlula kuwo, isibonisi sekristalu se-lcd sisebenzisa amandla amancane kunobunye ubuchwepheshe bokuboniswa.Okwesibili, izikrini ze-LCD zinokukhanya okuphezulu nokugqama.Ngenxa yezakhiwo zama-molecule e-crystal ewuketshezi, isibonisi sekristalu se-lcd singaveza imibala egqamile nezithombe ezicacile.Ngaphezu kwalokho, i-Lcd Display ine-engeli enkulu yokubuka, ukuze ukubuka izithombe kunganqunyelwe i-engeli.Ekugcineni, isibonisi sekristalu se-lcd sinesivinini sokuphendula esisheshayo futhi singabonisa izithombe eziguqukayo zesivinini esikhulu, ezifanele ukubuka amamuvi nokudlala imidlalo.
Ngokwezidingo ezahlukene zohlelo lokusebenza, izikrini ze-LCD zingahlukaniswa zibe izinhlobo eziningi.Uhlobo oluvame kakhulu i-TFT-Lcd Display (Thin-Film Transistor Liquid Crystal Display).Izikrini ze-TFT-LCD zilawula ama-molecule ekristalu ewuketshezi ngama-transistors efilimu azacile, anobuningi be-pixel obuphezulu nekhwalithi yesithombe engcono.Ngaphezu kwalokho, kukhona i-TN-Ips Lcd (Twisted Nematic Liquid Crystal Display), IPS-Lcd Display (In-Plane Switching Liquid Crystal Display), izikrini ze-VA-LCD (Vertical Alignment Liquid Crystal Display) nezinye izinhlobo ezahlukene zezikrini ze-LCD.Uhlobo ngalunye lunezici zalo ezithile kanye nezinkambu zokusetshenziswa.Ngokwezimo ezihlukene zohlelo lokusebenza, isibonisi sekristalu se-lcd singahlukaniswa ngezikrini ze-LCD zezimboni, izikrini ze-LCD zezimoto, kanye ne-Consumer electronics Lcd Display.Ukukhetha uhlobo olulungile lwesikrini se-LCD kubalulekile ukuze uhlangabezane nezidingo zomuntu ngamunye.
Lapho ukhetha futhi uthenga i-Ips Lcd, kunezici ezimbalwa ezibalulekile okufanele zicatshangelwe.Okokuqala usayizi wesikrini.Isibonisi se-Lcd sitholakala ngamasayizi ahlukahlukene, futhi kuyadingeka ukukhetha usayizi ofanele ngokuya ngokwezimo zokusetshenziswa zangempela kanye nezidingo.Isibonelo, uma uthenga i-TV, udinga ukucabangela usayizi wegumbi nebanga lokuyibuka.Okwesibili isixazululo.Ukulungiswa kunquma ukucaca kwesithombe kwesikrini.Isikrini esinokulungiswa okuphezulu singabonisa imininingwane eyengeziwe, kodwa futhi sikhulisa izimfuneko zehadiwe.Okwesithathu izinga lokuvuselela.Izinga lokuvuselela linquma ukushelela kwezithombe eziboniswa esikrinini, futhi izinga eliphezulu lokuvuselela linganikeza izithombe ezicacile nezishelelayo.Ekugcineni kukhona isikhombikubona nezinketho zokuxhuma.Ngokwezidingo zezinto ezisetshenziswayo, kuyadingeka ukuqinisekisa ukuthi isikrini se-LCD sinezindawo zokusebenzelana ezifanele kanye nezinketho zokuxhuma ukuze zixhumeke nezinye izinto zokusebenza.
Ngaphezu kwalezi zici eziyisisekelo, kuneminye imisebenzi eyengeziwe nezici ezingacatshangelwa.Isibonelo, amanye ama-Ips Lcd anobuchwepheshe obunqanda ukuxhopha ukuze banciphise ukucwebezela kanye nokuxhopha ezindaweni ezikhanyayo.Kukhona nezikrini ze-LCD ezinombala obanzi we-gamut namandla we-HDR ukuze uthole izithombe ezingokoqobo nezicacile.Ngaphezu kwalokho, umsebenzi wesikrini sokuthinta uyisidingo esivamile, esingasetshenzwa kalula ngokuthinta.
Ngokuvamile, ukukhetha nokuthenga isikrini se-LCD kudinga ukucatshangelwa okubanzi kwezinto eziningi.Izimo ezihlukene zohlelo lokusebenza kanye nokuthandwayo komuntu siqu kungase kube nezidingo ezihlukile.Ukuqonda imigomo, izici nokuhlukaniswa kwe-Ips Lcd kungasisiza ukuthi sikhethe kangcono imikhiqizo evumelana nezidingo zethu.Ngaphambi kokuthenga, kuyanconywa ukuthi ufunde imininingwane yomkhiqizo kanye nokubuyekezwa komsebenzisi ukuze uqinisekise ukuthi ukhetha isikrini se-LCD esizinzile nesithembekile.
