I-LCD igama eliphelele le-Liquid Crystal Display, ikakhulukazi i-TFT, UFB, TFD, STN nezinye izinhlobo zesibonisi se-LCD azikwazi ukuthola izindawo zokufaka zohlelo kulabhulali ye-Dynamic-link.
Isikrini se-LCD se-laptop esisetshenziswa kakhulu yi-TFT.I-TFT (Thin Film Transistor) ibhekisela ku-transistor yefilimu ezacile, lapho iphikseli ye-LCD ngayinye ishayelwa i-transistor yefilimu ezacile ehlanganiswe ngemuva kwephikseli, evumela ukuboniswa kwesikrini okunesivinini esikhulu, ukukhanya okuphezulu, nokugqama okuphezulu.Njengamanje ingelinye lamadivayisi angcono kakhulu wokubonisa umbala we-LCD kanye nedivayisi yokubonisa evamile kumakhompyutha aphathekayo namadeskithophu.Uma kuqhathaniswa ne-STN, i-TFT inokugcwalisa umbala okuhle kakhulu, ikhono lokubuyisela, nokugqama okuphezulu.Isengabonakala ngokucacile elangeni, kodwa okubi ukuthi idla amandla amaningi futhi inezindleko eziphezulu.
Yini i-LED
I-LED isifinyezo se-Light Emitting Diode.Izinhlelo zokusebenza ze-LED zingahlukaniswa ngezigaba ezimbili: okokuqala, izikrini zokubonisa ze-LED;Okwesibili ukusetshenziswa kwe-LED single tube, okuhlanganisa i-backlight LED, i-infrared LED, njllIzikrini zokubonisa ze-LED , Idizayini kanye nezinga lobuchwepheshe bokukhiqiza laseShayina livumelana ngokuyisisekelo nezindinganiso zamazwe ngamazwe.Isikrini sokubonisa se-LED ishidi lokumisa ikhompuyutha elineyunithi yokubonisa engu-5000 yuan, ehlanganisa amalungu afanayo e-LED.Isebenzisa idrayivu yokuskena kagesi ophansi futhi inezici zokusetshenziswa kwamandla okuphansi, impilo yesevisi ende, izindleko eziphansi, ukukhanya okuphezulu, amaphutha ambalwa, i-engeli yokubuka enkulu, nebanga elide lokubuka.
Umehluko phakathi kwesikrini sokubonisa se-LCD nesibonisi sesikrini se-LED
Izibonisi ze-LEDzibe nezinzuzo ngaphezu kwezibonisi ze-LCD mayelana nokukhanya, ukusetshenziswa kwamandla, i-engeli yokubuka, nezinga lokuvuselela.Ngokusebenzisa ubuchwepheshe be-LED, kungenzeka ukwenza izibonisi ezizacile, ezikhanyayo, futhi ezicacile kunama-LCD.
1. Isilinganiso sokusetshenziswa kwamandla kwe-LED kuya ku-LCD cishe singu-1:10, okwenza i-LED isebenzise amandla kakhudlwana.
2. I-LED inezinga eliphezulu lokuvuselela nokusebenza okungcono kuvidiyo.
3. I-LED inikeza i-engeli yokubuka ebanzi efika ku-160 °, engabonisa imibhalo ehlukahlukene, izinombolo, izithombe ezinemibala, nolwazi lokugqwayiza.Ingadlala amasiginali wevidiyo yombala njenge-TV, ividiyo, i-VCD, iDVD, njll.
4. Isivinini sokusabela kwesici ngasinye sezikrini zokubonisa ze-LED siphindwe izikhathi ezingu-1000 kunezikrini ze-LCD LCD, futhi zingabukwa ngaphandle kwephutha ngaphansi kokukhanya okunamandla, futhi zingakwazi ukuzivumelanisa nezinga lokushisa eliphansi elingu -40 degrees Celsius.
Kalula nje, i-LCD ne-LED ubuchwepheshe bokubonisa obuhlukene.I-LCD iyisikrini sokubonisa esakhiwe ngamakristalu awuketshezi, kuyilapho i-LED iyisikrini esiboniswa ngama-diode akhipha ukukhanya.
I-backlight ye-LED: Ukonga amandla (30% ~ 50% ngaphansi kwe-CCFL), intengo ephezulu, ukukhanya okuphezulu nokugcwala.
I-backlight ye-CCFL: Uma iqhathaniswa ne-backlight ye-LED, idla amandla amaningi (asengaphansi kakhulu kune-CRT) futhi ishibhile.
Umehluko wesikrini: I-backlight ye-LED inombala ogqamile nokugcwala okuphezulu (i-CCFL ne-LED inemithombo yokukhanya yemvelo ehlukile).
