Mu dziko lopikisana kwambiri la kupanga zowonetsera zapamwamba, kusiyana pakati pa utsogoleri wamsika ndi kutha ntchito nthawi zambiri kumabwera chifukwa cha chinthu chimodzi: kulondola. Kupanga ndi kuyang'ana ma Low-Temperature Polycrystalline Silicon (LTPS) arrays—maziko a zowonetsera za OLED ndi LCD zomwe zimakhala ndi mawonekedwe apamwamba, zogwira ntchito kwambiri—kufuna kulekerera komwe kumakankhira malire a uinjiniya. Kukwaniritsa kulondola kwakukulu kumeneku kumayamba ndi maziko enieni a makinawo. Ichi ndichifukwa chake kusankha maziko a makina a granite a zida za LTPS Array sikuti ndi chisankho chongopanga, koma chofunikira kwambiri.
Njira zomwe zimagwiritsidwa ntchito popanga ma LTPS array, makamaka laser crystallization ndi photolithography ndi deposition steps, zimakhudzidwa kwambiri ndi phokoso la chilengedwe, kuphatikizapo kugwedezeka pang'ono ndi kusintha kwa kutentha. Ngakhale m'malo oyeretsera olamulidwa bwino kwambiri, kusintha pang'ono kungakhudze kwambiri kukolola ndi kufanana kwa ma array. Gawo lowunikira—lochitidwa ndi zida zapamwamba kwambiri kuti zitsimikizire kuti transistor iliyonse yapangidwa bwino—limafuna umphumphu waukulu kwambiri. Apa ndi pomwe maziko a makina a Granite a Flat panel display low-temperature polysilicon array amapambana kwambiri.
Kufunika kwa Kutentha ndi Kusintha kwa Kuwunika kwa LTPS
Ukadaulo wa LTPS umalola kuyenda kwa ma elekitironi mwachangu, zomwe zimathandiza ma transistors ang'onoang'ono komanso ogwira ntchito bwino komanso zimapangitsa kuti ziwonetsero zikhale ndi mphamvu zotsitsimula komanso kugwiritsa ntchito mphamvu zochepa. Komabe, kapangidwe kake ndi kakang'ono kwambiri, koyezedwa mu ma micron. Kuti zida zowunikira zovuta zipeze molondola, kuyeza, ndikusanthula zolakwika, nsanja yake yogwirira ntchito iyenera kukhala yopanda kusuntha komanso yosasinthasintha.
Zipangizo zakale monga chitsulo chopangidwa ndi chitsulo kapena chitsulo, ngakhale zili zolimba, zimakhala zosavuta kukulitsa kutentha. Coefficient of thermal expansion (CTE) ya chitsulo chodziwika bwino ndi yayikulu kwambiri kuposa ya granite wakuda. Izi zikutanthauza kuti kukwera pang'ono kwa kutentha kwamlengalenga, mwina digiri imodzi kapena ziwiri zokha, kudzapangitsa kuti kapangidwe ka makina achitsulo kakule ndikuchepa kwambiri. Pankhani yowunikira ma array, kutentha kumeneku kumayambitsa zolakwika za malo, kusalingana bwino kwa njira yowunikira, komanso kuwerenga kolakwika komwe kungayambitse kukana mapanelo abwino kapena kuvomereza omwe ali ndi vuto.
Mosiyana ndi zimenezi, kugwiritsa ntchito bedi la makina apadera a granite pa zipangizo za LTPS Array kumapereka nsanja yokhala ndi CTE yotsika kwambiri. Kukhazikika kwa kutentha kumeneku kumatsimikizira kuti mawonekedwe ofunika a makinawo—mtunda pakati pa sensa yoyezera ndi gawo la LTPS—umakhalabe wofanana, zomwe zimathandiza kuti muyeso wa sub-micron wokhazikika komanso wobwerezabwereza ukhale wofunikira pakuwongolera khalidwe.
Kuchepetsa ndi Kuuma kwa Kugwedezeka Kosayerekezeka
Kupatula kukhazikika kwa kutentha, zinthu zamkati mwa granite zimapereka mwayi waukulu poyang'anira mphamvu zosinthasintha komanso kugwedezeka. Makina owunikira apamwamba amagwiritsa ntchito magawo othamanga kwambiri komanso njira zamakono zowunikira zomwe zimapangitsa mayendedwe ang'onoang'ono amakina ndi kugwedezeka. Mphamvu zamkati izi, pamodzi ndi phokoso lakunja kuchokera kwa ogwiritsira ntchito mpweya kapena makina oyandikana nawo, ziyenera kuchepetsedwa mwachangu kuti mayendedwe asamawoneke bwino kapena kusakhazikika kwa kuwerenga.
Mphamvu yayikulu ya granite yochepetsera kutentha mkati, yomwe imalola kuti ichotse mphamvu yogwedezeka mwachangu kwambiri kuposa zitsulo, ndiyofunika kwambiri pano. Imagwira ntchito ngati choletsa kugwedezeka, kuonetsetsa kuti makinawo akhazikika mwachangu mu bata langwiro pambuyo pa mayendedwe aliwonse. Modulus yayikulu ya kusinthasintha ndi kuchuluka kwa mwalawo imathandizanso kuti kapangidwe kake kakhale kolimba kwambiri, kuchepetsa kutembenuka kwa static pansi pa kulemera kwa ma gantry system olemera, ma optical assemblies, ndi zipinda zotsukiramo.
Mwachidule, posankha makina a granite omalizidwa bwino kuti agwiritsidwe ntchito pa LTPS Array, mainjiniya akukhazikitsa maziko omwe ali olimba pa kutentha, opanda phokoso, komanso olimba. Kapangidwe kake ka zinthu zitatuzi sikangathe kukambidwa kuti akwaniritse zolinga zoyambira ndi zokolola zomwe zimafunikira popanga zowonetsera zamakono za LTPS.
Ubwino wa Uinjiniya kuchokera ku Chilengedwe
Chomaliza—maziko a makina a granite—sichili kutali ndi miyala yosweka. Ndi luso lapamwamba la metrology, lomwe nthawi zambiri limatsirizidwa mpaka kupirira komwe kumayesedwa mu low-micron range kapena ngakhale sub-micron. Njira zapadera zimagwiritsidwa ntchito kuti zitsimikizire kuti graniteyo yachepetsedwa kupsinjika komanso yathyathyathya bwino. Zinthu zachilengedwe zokonzedwa bwinozi zimapereka malo abwino kwambiri owunikira momwe makonzedwe onse amakina ndi owonera amayeretsedwa.
Kwa opanga zida za LTPS, kuphatikiza kwa granite yolondola kwambiri kumaonetsetsa kuti makina awo amatha kugwira ntchito mosalekeza pamlingo wapamwamba, zomwe zimapangitsa kuti pakhale zokolola zambiri komanso zowonetsera zabwino pamsika wa ogula. Ndi umboni wakuti pamene uinjiniya umafuna ungwiro wonse, kuyang'ana zinthu zachilengedwe zokhazikika kwambiri padziko lapansi kumapereka yankho lodalirika kwambiri.
