Embonini yesimanje, ezimotweni, kuma-electronics abathengi nakwamanye amasimu, ukubonisa okucwebezelayo okuwuketshezi (i-LCD) sekuyisikhathi eside kuyinto ebalulekile. Kusukela kuphaneli yokuqapha yemishini yamandla kuya esikrinini sokubonisa izinsimbi zemoto, kusukela kudeshibhodi yesithuthuthu kuya ku-interface yokusebenza kwemishini ye-photovoltaic, i-LCD isetshenziswa kabanzi ezimbonini ezahlukahlukene ngezinzuzo zayo zokuzinza, ukonga amandla kanye nokucaca. Kodwa-ke, kubathengi abaningi kanye nochwepheshe, kusenemibuzo eminingi mayelana nesimiso esiyinhloko, ukuhlukaniswa kanye nezimo ezisebenzayo ze-LCD. Namuhla, njengomkhiqizi ochwepheshe obelokhu ehileleke kakhulu emkhakheni we-LCD iminyaka engama-21, i-Future ikunikeza ulwazi oluphelele lwesayensi ethandwayo ye-LCD, ikusiza ukuthi uqonde ngokushesha izici eziyinhloko ze-logic kanye nokuhlukaniswa kwe-LCD, futhi inikeza ireferensi yokukhetha nokuthenga.
Okokuqala, ake sicacise incazelo eyinhloko: i-LCD, ebizwa ngokuthi i-Liquid Crystal Display, yonaiyidivayisi yokubonisa eyisicaba esebenzisa izici zokukhanya zekristalu eliwuketshezi ukubonisa izithombe nezinhlamvu ngokulawula ukuhlelwa kwama-molecule ekristalu eliwuketshezi. Uma kuqhathaniswa nokuboniswa kwendabuko kwe-CRT, i-LCD inezinzuzo zobukhulu obuncane, isisindo esilula, ukusetshenziswa kwamandla aphansi, ukungabikho kwemisebe kanye nokuboniswa okucacile, futhi ingenye yezobuchwepheshe bokubonisa ezisetshenziswa kakhulu emhlabeni. Isimiso sayo esiyinhloko sokusebenza asiyinkimbinkimbi: ikristalu eliwuketshezi ngokwayo ayikhiphi ukukhanya, futhi idinga ukuthembela kungqimba lokukhanya kwangemuva ukuze inikeze umthombo wokukhanya, futhi isiqondiso sokuzungeza kwama-molecule ekristalu eliwuketshezi silawulwa ama-electrode ukushintsha i-engeli yokungena kokukhanya kanye nokugqama, ngaleyo ndlela iveze izithombe nezinhlamvu ezahlukene esikrinini. Kalula nje, i-LCD ifana "nokushintsha kokukhanya". Ngokulawula ukuhlelwa kwama-molecule ekristalu eliwuketshezi, ukukhanya kungalawulwa ngokunembile, bese umsebenzi wokubonisa ungaqedwa.
Ngokwelungiselelo kanye nezici zokukhanya zama-molecule e-liquid crystal, ama-LCD ahlukaniswe kakhulu ngalezi zigaba: i-TN LCD, i-VA LCD, i-STN LCD kanye ne-FSTN LCD, phakathi kwazo i-TN ne-VA kuyizinhlobo ezisetshenziswa kakhulu embonini, ezimotweni nakwezinye izinkambu, futhi futhi ziyimikhiqizo eyinhloko yenzuzo ye-Feiyoute.
1、I-TN LCD (i-Twisted Nematic LCD). Lolu uhlobo lwe-LCD oluyisisekelo kakhulu nolusetshenziswa kakhulu, futhi futhi luwumkhiqizo osetshenziswa kakhulu emkhakheni wezimboni okwamanje. Izinzuzo zalo eziyinhloko ukuphendula okusheshayo (ngokuvamile i-1-5ms), ukusetshenziswa kwamandla okuphansi, izindleko ezingalawuleki, kanye nokuzinza okuhle, okungazivumelanisa nezidingo ezinzima zezigcawu zezimboni. Ububi be-TN LCD ukuthi i-engeli yokubuka incane kakhulu, futhi ukuphambuka kombala kuzovela uma kubukwa nge-engeli enkulu, kodwa kungahlangabezana ngokugcwele nezidingo zezimo eziningi zohlelo lokusebenza nge-engeli yokubuka eyodwa njengokuqapha kwezimboni kanye namamitha kagesi. I-Feiyoute ibilokhu ihileleke kakhulu emkhakheni we-TN LCD iminyaka engama-21, yazi kahle ubuchwepheshe obuyinhloko, futhi yathola isivuno esihamba phambili embonini esingu-99.5% emgqeni omusha wokukhiqiza ohlakaniphile, ihlinzeka ngemikhiqizo ye-TN LCD ezinzile futhi engabizi kakhulu yamandla kagesi, ukulawula kwezimboni kanye neminye imikhakha.
2、I-VA LCD (i-Vertical Alignment LCD). Izinzuzo eziyinhloko ze-VA LCD isilinganiso sokungafani okuphezulu kakhulu (ngokuvamile okungaphezu kuka-3000:1), ukukhiqizwa kombala ophezulu kanye ne-engeli yokubuka ebanzi, okungagcina umphumela wokubonisa ucacile kuma-engeli ahlukene, futhi kufanelekile ezigcawini ezidinga ikhwalithi yokubonisa ephezulu, njengezinsimbi zezimoto, ukuqapha kwe-photovoltaic kanye nemishini yokulawula yezimboni ephezulu. Uma kuqhathaniswa ne-TN LCD, isivinini sokuphendula se-VA LCD sihamba kancane, kodwa ngokuthuthukiswa okuqhubekayo kobuchwepheshe, sikwazile ukuhlangabezana nezidingo zezigcawu eziningi zezimoto nezezimboni. Isivuno semikhiqizo ye-VA LCD ye-Feiyoute sifinyelela ku-98%. Ngokusebenzisa ngcono inqubo, isivinini sokuzinza kanye nempendulo yemikhiqizo sithuthukiswa kakhulu ngenkathi kugcinwa ukuqhathanisa okuphezulu, okuhlangabezana nezidingo zamasimu aqondile aphezulu.
3、I-STN LCD (Super Twisted Nematic LCD), isibonisi sekristalu eliwuketshezi oluyi-super twisted nematic, inguqulo ethuthukisiwe ye-TN LCD. Ngokwenza ngcono i-angle yokujika yama-molecule ekristalu eliwuketshezi, i-angle yokuqhathanisa kanye nokubuka iyathuthukiswa, enezici zokusetshenziswa kwamandla aphansi kanye nokuzinza okuphezulu. Inezinhlobo eziningi zokusetshenziswa, futhi umongo wayo ufanelekela izinsimbi zezimboni, amaphaneli okulawula amandla, amadivayisi aphathekayo, izibonisi ezisizayo ezifakwe emotweni ezisezingeni eliphansi kanye nezinye izigcawu. I-Feiyoute ingahlinzeka ngemikhiqizo ye-STN LCD eyenziwe ngokwezifiso ukuze ivumelane nezimo zokusebenza ezinzima ezimbonini eziningi.
4、I-FSTN LCD (i-Film Super Twisted Nematic LCD), inguqulo ethuthukisiwe ye-twisted nematic (TN)LCD, exazulula inkinga ye-engeli yokubuka emincane kanye nokungafani okuphansi kwesikrini se-TN ngokwenza ngcono i-engeli yokubuka kanye nokungafani ngefilimu yesinxephezelo, futhi inezinzuzo zokusetshenziswa kwamandla aphansi kanye nokuqina okuphezulu kwesikrini se-TN. Inezinhlobo eziningi zokusetshenziswa, futhi umongo wayo ufanelekela izinsimbi zezimboni, imishini yamandla, isibonisi esisekelayo esifakwe emotweni kanye nezinye izigcawu. I-Feiyoute ingahlinzeka ngemikhiqizo ye-FSTN LCD eyenziwe ngokwezifiso ukuze ihlangabezane nezidingo zezimo zokusebenza ezinzima.
Njengebhizinisi likazwelonke lobuchwepheshe obuphezulu elineminyaka engu-21 yesipiliyoni sokukhiqiza i-LCD, i-Feiyoute igxile ocwaningweni, ekuthuthukisweni, ekukhiqizweni nasekulungiselelweni ngokwezifiso kwe-TN ne-VA LCD, futhi ihlinzeka ngezixazululo ze-LCD ezenziwe ngokwezifiso zezimboni ezahlukahlukene ngohlelo locwaningo nokuthuthukiswa oluphelele, ukulawulwa kwekhwalithi okuqinile kanye nemigqa yokukhiqiza ehlakaniphile ethuthukisiwe. Kungakhathaliseki ukuthi umkhiqizo we-TN LCD oyisisekelo noma umkhiqizo we-VA LCD osezingeni eliphezulu, i-Feiyoute ingahlangabezana nezidingo ezahlukahlukene zamakhasimende ngesivuno esikhulu kanye nokuqina okuphezulu, futhi isize amakhasimende ukuthuthukisa ukuncintisana komkhiqizo wawo.
