Kwiminyaka yakutshanje, iintengiso eziphathwayo zangaphandle ziye zabaluleka ekubambeni ingqalelo yabathengi abanokubakho. Indlela eyaziwayo kukusebenzisa izikrini ze-LED zefestile ngasemva, ezibukekayo kwaye ziluncedo kumashishini kunye nabakhweli.
Ezi zikrini zifikelela kubaphulaphuli abaninzi nabahlukeneyo njengoko iibhasi zigubungela iindlela ezibanzi kwiindawo zokuhlala kunye nezorhwebo. Oku kufikeleleka kubanzi kuqinisekisa ukujoliswa okusebenzayo kwabathengi abaninzi abanokubakho abavela kwiidemografi ezahlukeneyo, ukwandisa impumelelo yokunyusa.
Ukongeza, izikrini ze-LED zinika ukucaca okukhethekileyo imini nobusuku. Ukukhanya kwazo kuqinisekisa ukuba iintengiso zibonwa lula, nokuba yinjikalanga enelanga okanye kubusuku obumnyama, nto leyo ezenza zisebenze ngakumbi kuneebhodi zentengiso ezimile zemveli.
