Kwiteknoloji yanamhlanje ephucuka ngokukhawuleza, iziboniso ze-LED ziye zanda kakhulu kwizikrini ezibalulekileyo zasezidolophini, kwiithiyetha zasekhaya, kwimiboniso yeqonga, nakwezinye izinto, ezithandwa ngenxa yokukhanya kwazo okuphezulu kunye nemibala eqaqambileyo. Emva kwala mava amangalisayo okubonakalayo, izinto ezingaqhelekanga zomhlaba zidlala indima ebalulekileyo engenakutshintshwa.
Izinto ezingaqhelekanga zomhlaba azibizwa ngokuba zizinto ezinqongopheleyo kodwa ngenxa yobunzima bokuzikhupha nokuzihlulahlula. Ngenxa yeempawu zazo zomzimba nezekhemikhali ezikhethekileyo, ezi zinto ziye zaba “sisixhobo esiyimfihlo” sokuphucula ukusebenza kwesibonisi se-LED.
Ukusetyenziswa kweziyobisi zomgquba ongaqhelekanga kuphucula kakhulu ukusebenza kakuhle kokukhanya. Ngokusebenzisa izinto ezithileumhlaba ongaqhelekanga Izinto eziluhlaza okwesibhakabhaka ze-LED, azigcini nje ngokwandisa ukusebenza kakuhle kokukhanya kwaye zinciphise i-voltage yokuqhuba kodwa zikwandisa nobomi be-LED.Oku kuthetha ukuba izikrini ze-LED zigcina amandla kakuhle kwaye zingabizi kakhulu ekugcinweni
Izinto ezingaqhelekanga zomhlaba ikwagqwesa ekwenzeni ngcono iimpawu ze-LED spectral. Ukusebenzisa i-rare earths kwenza ukukhanya okukhutshiweyo kusondele ekukhanyeni kwendalo, kuphucula ukuchaneka kombala kwaye kudala amava okubonakalayo akhululekileyo. Nokuba kusasazwa iividiyo ezikumgangatho ophezulu okanye kuboniswa ukukhanya okuqaqambileyo eqongeni, i-rare earths yenza imifanekiso icace ngakumbi kwaye ifane nobomi.
Ngaphezu koko, i-rare earths izinzisa ubushushu bombala we-LED ngendlela emangalisayo. Phantsi kobushushu obuhlukeneyo kunye nokufuma, ii-rare earth-doped LEDs zigcina ubushushu bombala obufanayo, ziqinisekisa ukuba izibonisi azifiphali okanye aziguquguquki kumbala.
Ezinye iindawo ezinqabileyo ezifana i-cerium (iCe)kwaye i-europium (Eu) yonyusa ukukhanya okukhanyayo ngokufunxa ukukhanya okuluhlaza okwesibhakabhaka nokuyiguqula ibe kukukhanya okutyheli, okwenza izibonisi zibonakale ngokucacileyo nokuba kukukhanya okunamandla kwangaphandle.
Okuphawulekayo kukuba, ukusebenzisa i-rare earth doping kuphucula ukumelana nemitha ye-LED eziluhlaza okwesibhakabhaka, kunciphisa iingozi zomonakalo wemitha, kwaye kunciphisa amaqondo obushushu okusebenza, kuthintela ukuwohloka kokusebenza kunye nokuncipha kobomi obubangelwa kukushisa kakhulu.
Njengoko iteknoloji iqhubeka,usetyenziso lomhlaba onqabileyokwimiboniso ye-LED iya kukhula ngakumbi. Kwixesha elizayo, singalindela ukuba iziboniso ze-LED ezisebenzisa amandla amaninzi, ezicacileyo, nezizinzileyo, zinikezele ngeenkonzo ezingcono.e iyothusa izidlo ezibonakalayo. Emva kwayo yonke loo nto, izinto ezinqabileyo zomhlaba iza kuqhubeka nokukhupha ixabiso layo elikhethekileyo njengamandla aqhubayo kubuchwepheshe bokubonisa.
