Izikrini zamaselula, ezaziwa nangokuthi izikrini zokubonisa, zisetshenziselwa ukubonisa izithombe nemibala.Usayizi wesikrini ukalwa nge-diagonally, ngokuvamile ngamayintshi, futhi ubhekisela kubude be-diagonal besikrini.Okubalulekile kwesikrini Ngokuthandwa kancane kancane kwesikrini sombala weselula, okokusebenza kwesikrini sikamakhalekhukhwini kuya ngokuya kubaluleke kakhulu.
Izikrini zemibala zomakhalekhukhwini ziyahlukahluka ngenxa yekhwalithi ye-LCD ehlukene kanye nocwaningo nokuthuthukiswa kobuchwepheshe.Kukhona cishe i-TFT, TFD, UFB, STN ne-OLED.Ngokuvamile, imibala eminingi ongabonisa ngayo, isithombe siyinkimbinkimbi, futhi izingqimba zicebile.
Okubalulekile kwesikrini
Ngokuthandwa kancane kancane kwesikrini sombala weselula, i-material yesikrini somakhalekhukhwini iya ibaluleka kakhulu.Izikrini zemibala zomakhalekhukhwini ziyahlukahluka ngenxa yekhwalithi ye-LCD ehlukene kanye nocwaningo nokuthuthukiswa kobuchwepheshe.Kukhona cishe i-TFT, TFD, UFB, STN ne-OLED.Ngokuvamile, imibala eminingi ongabonisa ngayo, isithombe siyinkimbinkimbi, futhi izingqimba zicebile.
Ngaphezu kwalezi zigaba, amanye ama-LCDS angatholakala kwamanye omakhalekhukhwini, njengesikrini sase-Japan se-SHARP GF kanye ne-CG(continuous crystalline silicon)LCD.I-GF iwukuthuthukiswa kwe-STN, engathuthukisa ukugqama kwe-LCD, kuyilapho i-CG iyi-LCD enembayo ephezulu nekhwalithi ephezulu, engafinyelela ekulungisweni kwamaphikseli e-QVGA(240×320).
Songa isikrini se-TFT
I-TFT(Thin Film field effect Transistor) iwuhlobo lwe-matrix liquid crystal display (LCD)."Ingakwazi" ukulawula amaphikseli ngamanye esikrinini, okungathuthukisa kakhulu isikhathi sokusabela.Ngokuvamile, isikhathi sokusabela se-TFT siyashesha kakhulu, cishe ama-millisecond angu-80, futhi i-Angle ebonakalayo inkulu, ngokuvamile ingafinyelela ama-degree angu-130, ikakhulukazi asetshenziswa emikhiqizweni ephezulu.Okubizwa ngokuthi i-film film effect effect transistor kusho ukuthi iphoyinti ngalinye le-pixel le-LCD ku-LCD lishayelwa i-transistor yefilimu ehlanganiswe ngemuva.Ngakho-ke ingafinyelela isivinini esikhulu, ukukhanya okuphezulu, ulwazi lwesikrini sokugqama okuphezulu.I-TFT ingeye-matrix liquid crystal display esebenzayo, eshayelwa “i-matrix esebenzayo” kubuchwepheshe.Indlela iwukusebenzisa i-transistor electrode eyenziwe ubuchwepheshe befilimu encane, futhi usebenzise indlela yokuskena ukuze "udonse ngenkuthalo" ukuze ulawule ukuvulwa nokuvulwa kwanoma iyiphi indawo yokubonisa.Lapho umthombo wokukhanya ucwebezela, uqala ukhanyisa phezulu nge-polarizer ephansi futhi ukhanyise ngosizo lwama-molecule ekristalu ewuketshezi.Inhloso yokubonisa ifinyelelwa ngokufiphaza nokudlulisa ukukhanya.
I-Tft-lcd Liquid crystal display ifilimu encane yohlobo lwe-liquid crystal display, eyaziwa nangokuthi “umbala wangempela “(TFT).I-TFT liquid crystal ihlinzekwa nge-switch semiconductor ye-pixel ngayinye, i-pixel ngayinye ingalawulwa ngokuqondile yi-point pulse, ngakho-ke i-node ngayinye izimele ngokuqhathaniswa, futhi ingalawulwa ngokuqhubekayo, hhayi nje ukuthuthukisa isivinini sokusabela kwesikrini sokubonisa, kodwa futhi ingakwazi. lawula ngokunembile izinga lombala wesibonisi, ukuze umbala we-TFT liquid crystal uyiqiniso nakakhulu.I-TFT liquid crystal display ibonakala ngokugqama okuhle, ukugqama okuphezulu, umuzwa oqinile wesendlalelo, umbala ogqamile, kodwa kukhona nokushiyeka okuthile kokusetshenziswa kwamandla okuphakeme kanye nezindleko.Ubuchwepheshe be-TFT liquid crystal busheshise ukuthuthukiswa kwesikrini sombala weselula.Iningi lesizukulwane esisha sezingcingo eziphathwayo zesikrini sombala zisekela ukuboniswa kombala okungu-65536, kanti ezinye zize zisekele ukuboniswa kombala okungu-160,000.Ngalesi sikhathi, inzuzo yokugqama okuphezulu nombala ocebile we-TFT kubaluleke kakhulu.
