A LCD ehambayo(I-Liquid Crystal Display) luhlobo lwetekhnoloji yesikrini esetyenziswa rhoqo kwizixhobo eziphathwayo ezinjengee-smartphones kunye neetafile.Ngumboniso wephaneli ecaba esebenzisa iikristale zolwelo ukwenza imifanekiso kunye nemibala kwiscreen.
Izikrini ze-LCD zinemigangatho emininzi esebenza kunye ukuvelisa isiboniso.Amacandelo aphambili abandakanya isibane esingasemva, umaleko weekristale zolwelo, isihluzo sombala, kunye nepolarizer.Isibane sangasemva ngokuqhelekileyo sisibane sefluorescent okanye i-LED (Light-Emitting Diode) ebekwe emva kwesikrini, ibonelela ngokhanyiso oluyimfuneko.
Umaleko weekristale zolwelo umi phakathi kweeleya ezimbini zeglasi okanye zeplastiki.Iikristale zolwelo zenziwe ngamamolekyuli anokutshintsha ulungelelwaniso lwawo xa kusenziwa umbane.Ngokulawula imisinga yombane kwiindawo ezithile zesikrini, iikristale zolwelo zinokulawula ukudlula kokukhanya.
Umaleko wesihluzi sombala unoxanduva lokongeza umbala ekukhanyeni okudlula kwiikristale ezingamanzi.Iqulathe izihluzi ezibomvu, eziluhlaza, nezibhlowu ezinokuthi zenziwe zisebenze okanye zidityaniswe ukwenza uluhlu olubanzi lwemibala.Ngokuhlengahlengisa ubunzulu kunye nokudityaniswa kwale mibala iphambili, i-LCD inokubonisa imibala eyahlukeneyo kunye nemibala.
Iileya ze-polarizer zibekwe kumacala angaphandle epaneli ye-LCD.Banceda ukulawula ukuqhelaniswa kokukhanya okudlula kwiikristale zolwelo, ukuqinisekisa ukuba isikrini sivelisa umfanekiso ocacileyo nobonakalayo xa ujongwe ngaphambili.
Xa umsinga wombane usetyenziswa kwipixel ethile kwiIsikrini se-LCD, iikristale zolwelo kuloo pixel zilungelelaniswa ngendlela yokuba zithintele okanye zivumele ukukhanya kudlule.Oku kuguqulwa kokukhanya kudala umfanekiso ofunekayo okanye umbala kwiscreen.
I-LCDs eziselula zibonelela ngeenzuzo ezininzi.Banokubonelela ngemifanekiso ebukhali kunye eneenkcukacha, ukuveliswa kombala ngokuchanekileyo, kunye nezigqibo eziphezulu.Ukongeza, itekhnoloji yeLCD ngokuqhelekileyo inamandla ngakumbi xa kuthelekiswa nobunye ubugcisa bokubonisa njenge-OLED (i-Organic Light-Emitting Diode).
Nangona kunjalo, iiLCDs nazo zinemida ethile.Ngokuqhelekileyo bane-engile yokujonga elinganiselwe, okuthetha ukuba umgangatho womfanekiso kunye nokuchaneka kombala kunokuthotywa xa ujongwe kwii-engile ezigqithisileyo.Ngaphaya koko, izikrini ze-LCD ziyasokola ukufezekisa abamnyama abanzulu kuba isibane sangasemva sihlala sikhanyisa iipikseli.
Kwiminyaka yakutshanje, i-OLED kunye ne-AMOLED (i-Active-Matrix Organic Light-Emitting Diode) iziboniso ziye zafumana ukuthandwa kwishishini leselula ngenxa yeenzuzo zabo ngaphezu kwe-LCDs, kubandakanywa umlinganiselo ongcono wokuchasana, ii-angles zokujonga ngokubanzi, kunye nezinto ezincinci zefom.Nangona kunjalo, itekhnoloji ye-LCD ihlala ixhaphakile kwizixhobo ezininzi eziphathwayo, ngakumbi kwiinketho ezilungele uhlahlo lwabiwo-mali okanye izixhobo ezineemfuno ezithile zokubonisa.
