A i-LCD yeselula(I-Liquid Crystal Display) iwuhlobo lobuchwepheshe besikrini obuvame ukusetshenziswa kumadivayisi eselula njengama-smartphone namathebulethi.Isibonisi sephaneli eyisicaba esisebenzisa amakristalu awuketshezi ukudala izithombe nemibala esikrinini.
Izikrini ze-LCD ziqukethe izendlalelo ezimbalwa ezisebenza ndawonye ukukhiqiza isibonisi.Izingxenye eziyinhloko zifaka i-backlight, ungqimba lwamakristalu awuketshezi, isihlungi sombala, kanye ne-polarizer.Isibani sangemuva ngokuvamile siwumthombo wokukhanya we-fluorescent noma we-LED (Light-Emitting Diode) otholakala ngemuva kwesikrini, ohlinzeka ngokukhanya okudingekayo.
Ungqimba lwamakristalu awuketshezi luphakathi kwezingqimba ezimbili zengilazi noma zepulasitiki.Amakristalu awuketshezi akhiwe ngama-molecule angashintsha ukuqondanisa kwawo lapho kusetshenziswa umsinga kagesi.Ngokukhohlisa amaza kagesi ezindaweni ezithile zesikrini, amakristalu awuketshezi angakwazi ukulawula ukudlula kokukhanya.
Isendlalelo sesihlungi sombala sinesibopho sokwengeza umbala ekukhanyeni okudlula kumakristalu awuketshezi.Iqukethe izihlungi ezibomvu, eziluhlaza, neziluhlaza okwesibhakabhaka ezingenziwa zisebenze ngazinye noma zihlanganiswe ukuze kudalwe inhlobonhlobo yemibala.Ngokulungisa ukushuba kanye nenhlanganisela yale mibala eyinhloko, i-LCD ingabonisa ama-shades nemibala ehlukahlukene.
Izendlalelo ze-polarizer zibekwe ezinhlangothini zangaphandle zephaneli ye-LCD.Zisiza ukulawula ukuma kokukhanya okudlula kumakristalu awuketshezi, ukuqinisekisa ukuthi isikrini sikhiqiza isithombe esicacile nesibonakalayo uma sibukwa ngaphambili.
Lapho ugesi usetshenziswa kuphikseli ethile ku-Isikrini se-LCD, amakristalu awuketshezi kuleyo phikiseli aqondana ngendlela yokuthi avimbe noma avumele ukukhanya kudlule.Lokhu kuguqulwa kokukhanya kudala isithombe osifunayo noma umbala esikrinini.
Ama-LCD omakhalekhukhwini anikeza izinzuzo ezimbalwa.Bangahlinzeka ngezithombe ezibukhali nezinemininingwane, ukukhiqizwa kabusha kombala okunembile, nokulungiswa okuphezulu.Ukwengeza, ubuchwepheshe be-LCD buvamise ukonga amandla uma kuqhathaniswa nobunye ubuchwepheshe bokuboniswa njenge-OLED (I-Organic Light-Emitting Diode).
Nokho, ama-LCD anemikhawulo ethile.Ngokuvamile ane-engeli yokubuka elinganiselwe, okusho ukuthi ikhwalithi yesithombe nokunemba kombala kungehlisa isithunzi uma kubukwa ngama-engeli adlulele.Ngaphezu kwalokho, izikrini ze-LCD ziyazabalaza ukuzuza abamnyama abajulile ngoba ukukhanya kwangemuva kuhlala kukhanyisa amaphikseli.
Eminyakeni yamuva nje, izibonisi ze-OLED ne-AMOLED (Active-Matrix Organic Light-Emitting Diode) zithole ukuduma embonini yeselula ngenxa yezinzuzo zazo ngaphezu kwama-LCD, okuhlanganisa izilinganiso ezingcono zokuqhathanisa, ama-engeli wokubuka abanzi, nezici zefomu elincanyana.Noma kunjalo, ubuchwepheshe be-LCD buhlala budlangile kumadivayisi eselula amaningi, ikakhulukazi ezinkethweni ezivumelana nesabelomali noma kumadivayisi anezidingo ezithile zokubonisa.
