Imfuno yehlabathi jikelele yezibonisi ezinkulu nezisemgangathweni ophezulu zephaneli ezisicaba ziqhuba ubuchule obuqhubekayo kubuchwepheshe bokuvelisa. Eyona nto iphambili kweli shishini kukuveliswa kwezibonisi ezinkulu kusetyenziswa ubuchwepheshe be-Amorphous Silicon (a-Si). Nangona sele ikhulile, ukwenziwa kwe-a-Si kuhlala kungumdlalo obalulekileyo apho isivuno sibaluleke kakhulu, kubeka iimfuno ezingaqhelekanga kwizixhobo zokuhlola ezenzelwe ukuqinisekisa ukuthembeka kwe-array. Kwimishini enikwe umsebenzi wokuqinisekisa ukusebenza okugqibeleleyo kwe-pixel nganye kwiindawo ezinkulu zeglasi, isiseko siyinto yonke. Kulapho ukuthembeka kunye nokuzinza okungagungqiyo kweisiseko somatshini wegraniteUkuhlolwa kwe-flat panel display amorphous silicon array kuyaqala ukusebenza.
Izixhobo zokuhlola ze-silicon array ze-flat panel zanamhlanje zixhomekeke kwiinkqubo ezintsonkothileyo ze-optical neze-elektroniki ukuskena iindawo ezinkulu kunye nokufumanisa iziphene ezincinci. Ukuchaneka okufunekayo kwezi zixhobo zokuhlola kudla ngokuwela kuluhlu lwe-sub-micron. Ukufezekisa oku, zonke izixhobo zokuhlola kufuneka zakhiwe phezu kweqonga elikhuselekileyo ngokupheleleyo kwiintshaba eziqhelekileyo zokuchaneka: ukwanda kobushushu kunye nokungcangcazela.
Ukoyisa iThermal Drift ngenxa yokuSkena okuQhubekekayo
Kwimeko yokwenziwa kwemveliso, negumbi lokucoca elilawulwa kakhulu lihlangabezana nokuguquguquka okuncinci kobushushu. Izinto zesinyithi zemveli zisabela kakhulu kolu tshintsho, zanda okanye zincipha kwinkqubo eyaziwa ngokuba yi-thermal drift. Olu tshintsho lunokubangela ukuba indawo ehambelanayo ye-sensor yokujonga kunye nephaneli yokubonisa itshintshe kancinci ngexesha lomjikelo wokuskena, okukhokelela kwiimpazamo zejometri, ukufundwa okungachanekanga, kwaye ekugqibeleni, iziphene ezingachazwanga kakuhle. Ukufundwa okungachanekanga kunokukhokelela ekusetyenzisweni kwakhona okubiza kakhulu okanye ekukhuculweni kwephaneli elungileyo ngokugqibeleleyo.
Isisombululo sikwiimpawu zezinto ezisemgangathweni zegranite yendalo. Ukusetyenziswa kwegranite echanekileyo kwi-Flat panel display amorphous silicon array inspection kubonelela ngesiseko esine-Coefficient of Thermal Expansion (CTE) ephantsi kakhulu—engcono kakhulu kunentsimbi okanye i-aluminium. Le thermal inertia iqinisekisa ukuba i-geometry ebalulekileyo yomatshini wokuhlola ihlala izinzile ngokwemilinganiselo ngokuhamba kwexesha nangaphaya kokutshintsha okuncinci kobushushu. Ngokunciphisa ukushukuma kobushushu, igranite iqinisekisa ukuba inkqubo yokuhlola iyahambelana, iyaphindaphindeka, kwaye ithembeke kakhulu, iguqulela ngokuthe ngqo kwimveliso ephezulu.
IsiQinisekisi Esithuleyo: Ukudambisa iiNgcangcazelo ezincinci
Ngaphaya kwemiphumo yobushushu, ukuzinza okuguquguqukayo kwezixhobo zokuhlola akunakuxoxiswana ngako. Iindlela zokuskena ezinobuthathaka—ezisebenzisa iimoto ezikhawulezayo kunye neebheringi zomoya ukunqumla ii-substrates ezinkulu zeglasi—zivelisa ingxolo yangaphakathi yoomatshini. Ngaphezu koko, ukungcangcazela kwangaphandle okuvela kwiinkqubo ze-HVAC zezixhobo, oomatshini abanzima abakufutshane, kunye nokuhamba ngeenyawo kunokudlulisa umgangatho kwaye kuphazamise inkqubo yokuhlolwa.
I-Granite inomthamo ophezulu kakhulu wokudambisa ngaphakathi. Olu buchule bokufunxa ngokukhawuleza nokususa amandla oomatshini yingakho isiseko somatshini we-granite sovavanyo lwe-Flat panel display amorphous silicon array sisebenza njenge-volator yokungcangcazela ephezulu. Endaweni yokutshintsha okanye ukudlulisa ukungcangcazela okufana nesinyithi, isakhiwo esixineneyo, esikristale se-granite siguqula ngokukhawuleza la mandla e-kinetic abe bubushushu obungenamsebenzi, senza ngempumelelo iqonga elizolileyo nelizinzileyo. Oku kubalulekile kwiinkqubo zombono ezinesisombululo esiphezulu ezifuna ukuzola kwangoko ukuze zibambe imifanekiso ebukhali nechanekileyo yeempawu ezintsonkothileyo ze-array.
Ubuchule Bobunjineli Buqala Ngesiseko Sendalo
I-granite ekhethiweyo kwezi ziseko ayilolitye nje elirhabaxa; yinto ekumgangatho ophezulu, edla ngokuba yi-granite emnyama, ecutshungulwa ngocoselelo kwaye igqitywe ukuhlangabezana nemigangatho yeenkwenkwezi yokuba tyaba kwaye iqonde. Emva kokusikwa, ukugaywa, kunye nokulepha, ezi ziseko zifikelela kumlinganiselo wokumelana nomphezulu olinganiswa kwi-intshi ezizizigidi, zenza ireferensi yokwenyani ye-metrology-grade reference plane.
Oku kuzibophelela ekuzinzeni nasekuchanekeni ngokusebenzisa i-precision granite yiyo evumela abavelisi bezixhobo zokuhlola i-Flat panel display amorphous silicon array ukuba batyhale imida yesisombululo kunye ne-throughput. Ngokudibanisa le nto izinzileyo nehlala ixesha elide, iinjineli ziqinisekisa ukuba ukusebenza komatshini kuthintelwe kuphela ngumgangatho wezinto zayo zokuhamba kunye ne-optics, kungekhona kukungazinzi kwesakhiwo sayo esisisiseko. Kwimeko yokhuphiswano lokuvelisa i-display, ukukhetha isiseko se-granite sisigqibo esicwangcisiweyo esiqinisekisa ukuchaneka kwexesha elide kunye nokusebenza kakuhle.
