Kwiminyaka yakutshanje, itekhnoloji ye-Micro LED iqhubekile nokwenza impumelelo, idityaniswa nemfuno yetekhnoloji yokubonisa isizukulwana esilandelayo esiqhutywa yiMetaverse kunye nemimandla yeemoto, injongo yokuthengisa ibonakala isondele.Phakathi kwabo, ukukhanya okubomvu kwe-Micro LED chip ibisoloko iyibhodlela lobugcisa.Nangona kunjalo, inkampani yaseBritane ye-LED iguqule izinto ezingeloncedo kwizinto eziluncedo, kwaye yanciphisa ngempumelelo inkqubo kunye neendleko ezincitshisiweyo.
Ngenxa yokuqonda okunzulu kweempawu ze-gallium nitride, iPorotech ikhuphe i-Indium Gallium Nitride (InGaN) yokuqala yehlabathi esekwe ebomvu, eluhlaza okwesibhakabhaka kunye nohlaza iMicro LED ebonisa i-Micro LED kulo nyaka uphelileyo, yaphula ibhotile ebomvu, eluhlaza kunye neblue kufuneka idlule ngeendlela ezahlukeneyo. izinto , ezisombulula ngokufanelekileyo ingxaki ukuba ukukhanya okubomvu kwe-Micro LEDs kufuneka kudibanise iinkqubo ezininzi zezinto eziphathekayo, kwaye akusekho umda kuyo nayiphi na i-substrate, enokunciphisa ngempumelelo iindleko.
Itekhnoloji ephambili yePorotech igxile kwi "Dynamic Pixel Adjustment," ethi, njengoko igama libonisa, ilungelelanisa imibala.UZhu Tongtong ucacisile ukuba nje kusetyenziswa itshiphu kunye nepixel efanayo, nawuphi na umbala onokubonwa ngeliso lomntu unokukhutshwa, kwaye yonke imibala inokubonakala nge-gallium nitride ngokuxinana kwangoku kunye nokuqhuba umbane.Yinike nje umqondiso, unokutshintsha uMbala, oluhlaza ngokucofa iqhosha, eluhlaza, obomvu.” Nangona kunjalo, “uhlengahlengiso lwe-pixel eguqukayo” ayisiyongxaki yee-LEDs kuphela, kodwa ikwafuna inqwelomoya ekhethekileyo kunye nendlela yokuqhuba, ukukhangela ikhonkco lokubonelela kunye nabavelisi bentsebenziswano ukubonelela abathengi ngeMiboniso yabo encinci, ngoko kuthatha ixesha elide ukubeka.
UZhu Tongtong uphinde watyhila ukuba imodyuli yokwenyani eguqukayo eguqukayo kunye nemibala emininzi iya kuboniswa kwisiqingatha sesibini salo nyaka, kwaye kulindeleke ukuba kubekho ibhetshi yokuqala yeeprototypes ekupheleni kuka-Agasti nasekuqaleni kukaSeptemba.Ekubeni le teknoloji inquma ukukhanya kombala ngendlela yokuqhuba, iinkcukacha zesiphelo sezinto eziphathekayo kufuneka zilungiswe ukuze kuqinisekiswe ukuba nguwuphi umbala okhoyo kunye nombane onokuthi ulungelelaniswe kuwo;ukongeza, ikwayinxalenye enzima ngakumbi ukudibanisa imibala emithathu kwitshiphu enye.
Ekubeni ingekho i-pixel encinci yendabuko, obu buchwepheshe bunceda i-Micro LED ukuba ibe nendawo enkulu yokukhupha ukukhanya, ubungakanani be-chip enkulu, kunye nokusebenza okuphezulu phantsi kweemeko zesisombululo esifanayo.Icala lenkqubo alidingi ukuqwalasela umahluko wezinto eziphathekayo ngexesha lokudibanisa.Idigri yokuthelekisa, akuyomfuneko ukwenza ukukhula kwe-epitaxial ebomvu, eluhlaza, eluhlaza kanye, okanye ukupakisha ngokuthe nkqo.Ukongezelela, emva kokususa imiqobo yokuvelisa i-Micro LED, inokusombulula umsebenzi wokulungisa, ukuphucula isivuno, kunye nokunciphisa iindleko zokuvelisa kunye nexesha lokuthengisa.I-Gallium nitride inolu phawu, ukucoceka kombala wombala omnye kuya kukhukuliseka, kwaye umbala uya kuhamba kunye nokuxinana, ngoko sinokusebenzisa iimpawu zenkqubo yezinto eziphathekayo ukwenza umbala omnye ube nyulu kakhulu, nje kuphela izithintelo eziphathekayo kunye izinto ezibangela ukungcola kombala ziyasuswa., ngelixa usebenzisa umbala we-drift ukuwenza ube mkhulu, unokufezekisa umbala opheleleyo.
Uphando kwiMicro LED kufuneka lusebenzise ukucinga kwe-semiconductor
Ngaphambili, ii-LED zemveli kunye nee-semiconductors zineecology yazo, kodwa ii-Micro LEDs zazahlukile.Ezi zimbini kufuneka zidityaniswe kunye.Ukusuka kwizinto eziphathekayo, ukucinga, imigca yemveliso, kunye neshishini lonke, kufuneka baqhubele phambili nokucinga kwee-semiconductors.Izinga lesivuno kunye ne-silicon-backplanes elandelayo kufuneka ithathelwe ingqalelo, kunye nokuhlanganiswa kwenkqubo.Kwishishini leMicro LED, hayi eyona iqaqambileyo yeyona isebenzayo, kwaye iitshiphusi ezilandelayo, iindlela zokuqhuba kunye ne-SOC yokuthelekisa idigri kufuneka ziqwalaselwe.
Eyona ngxaki inkulu ngoku kukufezekisa ukuchaneka okufanayo, umgangatho, kunye nesivuno njenge-semiconductors ukuze utshatise kwaye udibanise nesiseko sesilicon.Akunjalo ukuba ii-LED zihlelwa njenge-LED kunye ne-semiconductors zihlelwa njenge-semiconductors.Ezi zimbini kufuneka zidityaniswe.Ukongeza ekusebenzeni okunamandla kwee-semiconductors, iimpawu ze-gallium nitride LEDs kufuneka zisetyenziswe.
Ii-LED ezincinci azisezizo ii-LED zemveli, kodwa kufuneka zenziwe ngokucinga kwe-semiconductor.Kwixesha elizayo, iMicro LED ayisiyiyo kuphela "imfuneko yokubonisa".Ekuhambeni kwexesha, iMicro LED kufuneka iphunyezwe kwi-terminal SOC ukuphucula unxibelelwano kunye nokusebenza kakuhle.Okwangoku, iitshiphusi ezininzi kakhulu azikabi sesona sisombululo sisesona sisiphelo.
