Kwihlabathi elinokhuphiswano olukhulu lokwenziwa kwemiboniso ephucukileyo, umahluko phakathi kobunkokeli bemarike kunye nokuphelelwa lixesha kudla ngokuba yinto enye: ukuchaneka. Ukwenziwa kunye nokuhlolwa kwee-arrays ze-Low-Temperature Polycrystalline Silicon (LTPS)—isiseko sezikrini ze-OLED kunye ne-LCD ezinesisombululo esiphezulu, ukusebenza okuphezulu—kufuna ukunyamezelana okutyhala imida yobunjineli. Ukufezekisa eli nqanaba liphezulu lokuchaneka kuqala ngesiseko esibonakalayo somatshini ngokwawo. Yingakho ukukhethwa kwesiseko somatshini we-granite kwizixhobo ze-LTPS Array kungekuphela nje ukhetho loyilo, kodwa yimfuneko esisiseko.
Iinkqubo ezibandakanyekayo ekwenziweni kwe-LTPS array, ngakumbi i-laser crystallization kunye ne-photolithography kunye namanyathelo okubeka izinto emva koko, zinovakalelo olukhulu kwingxolo yokusingqongileyo, kubandakanya ukungcangcazela okuncinci kunye notshintsho lobushushu. Kwanakwindawo ecocekileyo elawulwa ngononophelo, utshintsho oluncinci lunokuchaphazela kakhulu isivuno kunye nokufana kwe-array. Isigaba sokuhlola—esenziwa zizixhobo ezintsonkothileyo ukuqinisekisa ukuba yonke i-transistor yenziwe ngokugqibeleleyo—sifuna inqanaba eliphezulu le-structural integrity. Eli licandelo apho isiseko somatshini weGranite se-Flat panel display low-temperature polysilicon array espection sigqwesa ngokwenene.
Uvavanyo lwe-LTPS oluQinisekisa uBushushu noBunamandla
Itekhnoloji ye-LTPS ivumela ukuhamba ngokukhawuleza kwee-electron, ivumela ii-transistors ezincinci nezisebenza kakuhle kwaye ikhokelela kwiidisplays ezinezinga lokuhlaziya elimangalisayo kunye nokusetyenziswa kwamandla okuphantsi. Nangona kunjalo, izakhiwo ezibandakanyekayo zincinci, zilinganiswa ngee-microns. Ukuze izixhobo zokuhlola ezintsonkothileyo zifumane ngokuchanekileyo, zilinganise, kwaye zihlalutye iziphene, iqonga lazo lokusebenza kufuneka lingabi nantshukumo kwaye lingaguquguquki ngokwemilinganiselo.
Izinto zemveli ezifana nentsimbi ephosiweyo okanye intsimbi, nangona ziqinile, zisengozini yokwanda kobushushu. I-coefficient of thermal expansion (CTE) yentsimbi eqhelekileyo iphezulu kakhulu kuneyegranite emnyama. Oku kuthetha ukuba ukunyuka okuncinci kobushushu obungqongileyo, mhlawumbi idigri enye okanye ezimbini, kuya kubangela ukuba isakhiwo somatshini wentsimbi sande kwaye sinciphe kakhulu. Kwimeko yokuhlolwa kwe-array, oku kushukuma kobushushu kubangela iimpazamo zesimo, ukungalungelelani kwindlela ye-optical, kunye nokufundwa okungafanelekanga okunokubangela ukwaliwa kweepaneli ezilungileyo okanye ukwamkelwa kwezona zineziphene.
Ngokwahlukileyo koko, ukusetyenziswa kwebhedi yomatshini wegranite ekhethekileyo kwizixhobo ze-LTPS Array kubonelela ngeqonga eline-CTE ephantsi kakhulu. Olu zinzo lobushushu luqinisekisa ukuba i-geometry ebalulekileyo yomatshini—umgama ophakathi kwe-sensor yokulinganisa kunye ne-LTPS substrate—ihlala ingaguquki, nto leyo evumela ukulinganiswa kwe-sub-micron okuhlala kuphindaphindwa, okubalulekileyo kulawulo lomgangatho.
Ukudambisa kunye nokuqina kweNtshibiliko okungenakuthelekiswa nanto
Ngaphaya kozinzo lobushushu, iimpawu zezinto ezingaphakathi zegranite zibonelela ngenzuzo ebalulekileyo ekulawuleni amandla aguqukayo kunye nokungcangcazela. Iinkqubo zokuhlola eziphambili zisebenzisa amanqanaba esantya esiphezulu kunye neendlela zokuskena ezintsonkothileyo ezivelisa iintshukumo ezincinci zoomatshini kunye nokungcangcazela. La mandla angaphakathi, kunye nengxolo yangaphandle evela kubaphathi bomoya okanye oomatshini abakufutshane, kufuneka asuswe ngokukhawuleza ukuthintela ukufiphala kwentshukumo okanye ukungazinzi kokufunda.
Umthamo ophezulu wokudambisa ngaphakathi weGranite, uphawu oluyivumela ukuba ichithe amandla okungcangcazela ngokukhawuleza kakhulu kuneentsimbi, lubalulekile apha. Isebenza njengesithinteli sokutshotsho esingasebenziyo, iqinisekisa ukuba umatshini ubuyela kwimeko yokuzola okugqibeleleyo emva kwentshukumo nganye. I-modulus ephezulu yokuthamba kunye noxinano lwelitye ikwanegalelo kwisakhiwo esiqinileyo kakhulu, inciphisa ukuphambuka okungashukumiyo phantsi kobunzima beenkqubo ze-gantry ezinzima, iindibano ze-optical, kunye neegumbi ze-vacuum.
Ngokwenyani, ngokukhetha isiseko somatshini wegranite esigqityiweyo ngokuchanekileyo kwizicelo zeLTPS Array, iinjineli ziseka isiseko esizinzileyo kubushushu, esithuleyo ngokwesandi, nesiqinileyo ngokwesakhiwo. Olu hlobo lweempawu ezintathu alunakuxoxiswana ngalo ukuze kufezekiswe iinjongo zokuphuma kunye nemveliso efunekayo kwimveliso yeziboniso zeLTPS zanamhlanje.
Ukugqibelela kobunjineli kwiNdalo
Imveliso yokugqibela—isiseko somatshini wegranite—ayifani kakhulu namatye arhabaxa e-quarry. Yindlela yobugcisa ye-metrology, edla ngokugqitywa ngokunyamezela okulinganiswe kuluhlu lwe-low-micron okanye nakwi-sub-micron. Iindlela ezikhethekileyo zisetyenziswa ukuqinisekisa ukuba igranite ithomalalisiwe kuxinzelelo kwaye ithe tyaba ngokugqibeleleyo. Le nto yendalo icocekile kakhulu ibonelela ngeyona ndawo iphambili apho zonke iindlela zokulinganisa ezilandelelanayo kunye nezokukhanya zilinganiswa khona.
Kubavelisi bezixhobo ze-LTPS array, ukuhlanganiswa kwe-granite echanekileyo kakhulu kuqinisekisa ukuba oomatshini babo banokusebenza ngokuqhubekayo xa besebenza kakuhle, nto leyo eguqulela ngokuthe ngqo kwimveliso ephezulu kunye nokuboniswa okusemgangathweni kwimarike yabathengi. Bubungqina bokuba xa ubunjineli bufuna ukugqibelela okupheleleyo, ukujonga izinto zendalo ezizinzileyo zomhlaba kunika isisombululo esithembekileyo.
