Faasino i le vaega o loo i lalo ma tali le fesili mulimuli ane i le gagana lava lea e tasi e pei o le vaega:  Ala: O se diode malamalama-emitting faatulagaina (OLED) o se diode malamalama-emitting (LED) lea o le vaega electroluminescent emitting o se ata tifaga o tuufaatasiga faatulagaina e emits malamalama i le tali atu i se eletise i le taimi nei. O lenei faaputuga o meaola o loo i le va o ni eletise se lua; e masani lava, e lē itiiti ifo i le tasi o nei eletise e manino. O OLED e faʻaaogaina e fausia ai faʻaaliga numera i masini e pei o televise, komepiuta mataʻituina, feaveaʻi faiga e pei o telefoni poto, taʻaloga taʻaloga taʻavale ma PDAs. O se vaega taua o suʻesuʻega o le atinaʻeina o papaʻe OLED masini mo le faʻaaogaina i mautu-tulaga moli talosaga. E lua autu aiga o OLED: i latou faʻavae i luga o laʻititi molecules ma i latou faʻaaogaina polymers. O le faaopoopoina o ioni feaveai i se OLED e maua ai se sela eletise eletise (LEC) lea e iai sina eseesega o le auala e galue ai. O se OLED faʻaaliga mafai ona faʻagaioia ma se passive-matrix (PMOLED) poʻo le active-matrix (AMOLED) faʻatonutonu polokalame. I le polokalame PMOLED, o laina taʻitasi (ma laina) i le faʻaaliga e faʻatonutonu faʻasolosolo, tasi i le tasi, ae o le AMOLED faʻatonutonu faʻaaogaina se manifinifi-vaega transistor backplane e faʻaaoga saʻo ma fesuiaʻi taʻitasi pixel taʻitasi i luga pe tape, faʻatagaina mo maualuga maualuga ma lapoʻa faʻaaliga.  Fesili: O le ā le ituaiga o le LED e iai se vaega o meaola o loo iai i le va o ni eletise se lua?
