Mu isi ihanganirwa cyane mu gukora ibikoresho byo kwerekana amashusho bigezweho, itandukaniro riri hagati y’ubuyobozi bw’isoko n’ibidasaza akenshi riterwa n’ikintu kimwe: ubushishozi. Gukora no kugenzura ibikoresho byo mu bwoko bwa Low-Temperature Polycrystalline Silicon (LTPS) — ishingiro rya ecran za OLED na LCD zifite ubushobozi bwo hejuru, zikora neza — bisaba ubushobozi bwo kwihanganira ibintu butuma ibintu birushaho kuba byiza. Kugira ngo ugere kuri uru rwego rwo hejuru rw’ubuziranenge bitangirira ku rufatiro rw’imashini ubwayo. Niyo mpamvu guhitamo imashini ya granite ikoreshwa mu bikoresho bya LTPS Array atari uguhitamo igishushanyo gusa, ahubwo ni itegeko ry’ibanze.
Inzira zikoreshwa mu gukora LTPS array, cyane cyane crystallization ya laser na photolithography ikurikiraho no gushyiramo, zikunze kwibasirwa cyane n'urusaku rw'ibidukikije, harimo n'imitingito mito n'impinduka z'ubushyuhe. Ndetse no mu isuku igenzurwa neza cyane, impinduka nto zishobora kugira ingaruka zikomeye ku musaruro no ku buryo array ingana. Icyiciro cy'igenzura—gikorwa n'ibikoresho bigezweho cyane kugira ngo buri transistor ikore neza—gisaba urwego rwo hejuru rw'imiterere. Aha niho imashini ya Granite ikoreshwa mu kwerekana imiterere y'ibikoresho byo kugenzura imiterere ya polysilicon ifite ubushyuhe buke ikora neza cyane.
Igenzura rya LTPS rigena ubushyuhe n'ihindagurika ry'ingufu
Ikoranabuhanga rya LTPS rituma electron zigenda vuba, bigatuma transistors nto kandi zikora neza, bigatuma habaho kwerekana ibintu bifite umuvuduko utangaje wo kuvugurura no gukoresha ingufu nke. Ariko, imiterere ikoreshwa ni mikorosikopi, ipimwa muri mikorosikopi. Kugira ngo ibikoresho bigenzura bikomeye bibone neza, bipime kandi bisesengure inenge, urubuga rwabyo rw'imikorere rugomba kuba rudahinduka kandi rudahinduka mu buryo bunyuranye.
Ibikoresho gakondo nk'icyuma gishongeshejwe cyangwa icyuma, nubwo bikomeye, bikunze kwibasirwa no kwaguka k'ubushyuhe. Igipimo cyo kwaguka k'ubushyuhe (CTE) ku byuma bisanzwe kiri hejuru cyane ugereranyije n'icya granite yirabura. Ibi bivuze ko kwiyongera gato k'ubushyuhe bwo mu kirere, wenda dogere imwe cyangwa ebyiri gusa, bizatuma imiterere y'icyuma yaguka kandi igacika cyane. Mu rwego rwo kugenzura imiterere y'urutonde, uku guhindagurika k'ubushyuhe bitera amakosa mu mwanya, kugorana mu nzira y'urumuri, ndetse n'ingero zishobora kuba zitari zo zishobora gutuma paneli nziza zitakirwa cyangwa kwemerwa n'izifite inenge.
Ku rundi ruhande, gukoresha imashini yihariye ya granite ku bikoresho bya LTPS Array bitanga urubuga rufite CTE nkeya cyane. Uku guhagarara k'ubushyuhe byemeza ko imiterere y'imashini—intera iri hagati y'icyuma gipima n'icyuma cya LTPS—igumaho idahinduka, bigatuma haboneka ibipimo bihoraho kandi bishobora gusubiramo by'ingenzi mu kugenzura ubuziranenge.
Kudakomera no Kudakomera ku buryo budasanzwe
Uretse ubushyuhe buhamye, imiterere y’ibintu bya granite itanga inyungu ikomeye mu gucunga imbaraga zihindagurika n’imitingito. Sisitemu zo kugenzura zigezweho zikoresha ibyiciro byihuse n’uburyo bugezweho bwo gushakisha butanga ingendo nto za mekanike n’imitingito. Izi mbaraga z’imbere, hamwe n’urusaku rwo hanze ruturuka ku bikoresho bikoresha ikirere cyangwa imashini zegeranye, zigomba guhindurwa vuba kugira ngo hirindwe ko imiterere y’ikirere idahinduka cyangwa ngo habeho imihindagurikire y’ikirere idahindagurika.
Ubushobozi bwinshi bwo gufunga imbere muri Granite, imiterere ituma ibasha gusohora ingufu zihindagurika vuba cyane kurusha ibyuma, ni ingenzi cyane hano. Ikora nk'ikintu kiyifasha gufunga, gituma imashini isubira mu mwanya wayo w'ituze nyuma ya buri rugendo. Uburyo bwinshi bwo guhindagurika no gucucika kw'ibuye nabyo bigira uruhare mu gutuma imiterere yayo ikomera cyane, bigabanura uburyo bwo guhindagurika bitewe n'uburemere bw'ibikoresho biremereye byo mu ikoranabuhanga, ibyuma biteranya urumuri, n'ibyumba bisukura.
Mu by’ukuri, mu guhitamo imashini ya granite yuzuye neza yo gukoresha muri LTPS Array, injeniyeri barimo gushyiraho urufatiro ruhamye mu bushyuhe, rutuje mu ijwi, kandi rudahindagurika mu miterere. Iyi miterere y’ibintu bitatu ntabwo ivugwaho rumwe kugira ngo hagerwe ku ntego z’umusaruro n’umusaruro bikenewe mu gukora ecran za LTPS zigezweho.
Ubuhanga butunganye buturuka ku bidukikije
Igicuruzwa cya nyuma—imashini ya granite—kiratandukanye cyane n’amabuye y’agaciro akomeye. Ni ubuhanga buhanitse mu gupima, akenshi bigabanurwa mu buryo bwo kwihanganira ibintu bipimirwa mu bwoko bwa mikoroni nke cyangwa ndetse no mu bwoko bwa mikoroni nto. Hakoreshwa ubuhanga bwihariye kugira ngo granite igabanuke kandi igororoke neza. Iki gikoresho karemano gitunganyijwe cyane gitanga urwego rw’ibanze aho imiterere yose ya mekanike n’iy’urumuri igenzurwa.
Ku bakora ibikoresho bya LTPS, guhuza granite igezweho bituma imashini zabo zishobora gukora neza cyane, bigatuma umusaruro uba mwinshi kandi zigatanga umusaruro mwiza ku isoko ry’abaguzi. Ni igihamya cy’uko iyo ubwubatsi busaba ubwiza busesuye, kureba ku bikoresho karemano bihamye ku isi bitanga igisubizo cyizewe cyane.
