I roto i te ao whakataetae nui o te hanga whakaaturanga matatau, ko te rerekētanga i waenga i te kaiārahi mākete me te tawhito o te mākete ka heke ki te kotahi te mea: te tika. Ko te hanga me te tirotiro i ngā huinga Polycrystalline Silicon (LTPS) Pāmahana-Iti—te turanga mō ngā mata OLED me te LCD taumira teitei, mahi teitei—e hiahia ana ki ngā manawanui e pana ana i ngā rohe o te hangarau. Ko te whakatutuki i tēnei taumata tino teitei o te tika ka tīmata ki te turanga ā-tinana o te mīhini tonu. Koia te take ko te whiriwhiri i tētahi turanga mīhini karāhe mō ngā taputapu LTPS Array ehara i te mea he kōwhiringa hoahoa noa iho, engari he whakaritenga taketake.
Ko ngā tukanga e whai wāhi ana ki te hanga i te ara LTPS, inā koa ko te whakatioatatanga laser me ngā mahi whakaahua me te whakatakotoranga i muri mai, he tino tairongo ki te haruru taiao, tae atu ki ngā wiri ngawari me ngā nekehanga wera. Ahakoa i roto i te taiao rūma ma e tino whakahaerehia ana, ka taea e ngā huringa iti te pā nui ki te hua me te ōritetanga o te ara. Ko te wāhanga tirotiro—e mahia ana e ngā taputapu tino matatau hei whakarite kia tino tika te hanganga o ia transistor—me nui ake te hanganga o te hanganga. Koinei te rohe e tino pai ai te turanga mīhini Granite mō ngā taputapu tirotiro ara polysilicon pāmahana-iti whakaatu papatahi.
Te Hiranga Wera me te Hihiri o te Tirotiro LTPS
Mā te hangarau LTPS ka tere ake te nekenekehanga o ngā irahiko, ka taea ai ngā transistors iti ake, whai hua ake, ā, ka hua ake he whakaaturanga me ngā tere whakahou whakamiharo me te iti ake o te whakapaunga hiko. Heoi, he moroiti rawa ngā hanganga e whai wāhi ana, e inehia ana i roto i ngā maikorona. Kia tika ai te kimi, te ine, me te tātari i ngā hapa o ngā taputapu tirotiro matatini, me noho kore nekeneke tōna papa mahi, me te kore e rerekē te rahi.
Ahakoa he pakari ngā rauemi tuku iho pērā i te rino maka, te maitai rānei, he ngāwari ki te horapa wera. He nui ake te tauwehenga horapa wera (CTE) mō te maitai noa i tērā o te karāhe pango. Ko te tikanga o tēnei, mā te pikinga iti o te pāmahana taiao, he kotahi, he rua rānei ngā nekehanga pea, ka nui ake te horapa me te whakawhāiti o te hanganga mīhini maitai. I roto i te horopaki o te tirotiro rarangi, ka puta he hapa tūnga, he hē te tūnga o te ara whatu, me te kore pea e tika ngā pānui ka hua ake te whakakorenga o ngā panera pai, te whakaaetia rānei o ngā panera hapa.
I tetahi atu taha, mā te whakamahinga o tētahi moenga mīhini karāhe motuhake mō ngā taputapu LTPS Array ka whakaratohia he tūāpapa me te CTE tino iti. Mā tēnei pumau wera ka noho pūmau te āhua matua o te mīhini—te tawhiti i waenga i te pūoko ine me te papa LTPS—e āhei ai te ine i raro i te maikorone rite tonu, ka taea te whakahoki anō, e tika ana mō te whakahaere kounga.
Te Whakaiti me te Pakari o te Wiri Kore e Taurite
Haunga te pumau o te wera, he painga nui ngā āhuatanga o roto o te karāhe ki te whakahaere i ngā kaha hihiri me ngā wiri. Ka whakamahia e ngā pūnaha tirotiro matatau ngā wāhanga tere-teitei me ngā tikanga matawai matatau e whakaputa ana i ngā nekehanga me ngā wiri iti. Me tere te whakakore i ēnei kaha o roto, me te haruru o waho mai i ngā kaiwhakahaere hau, i ngā mīhini tata rānei, kia kore ai e pōuri te nekehanga, e kore rānei e pumau te pānui.
He mea nui te kaha whakamākū o roto o te karāneti, he āhuatanga e āhei ai ia ki te hora i te kaha wiri tere atu i ngā konganuku. He mea whakamākū tōna mahi, kia tere ai te noho o te mīhini ki te āhua marino i muri i ia nekehanga. Ko te kaha o te kōhatu ki te ngāwari me te mātotoru ka whai wāhi atu ki tētahi hanganga tino pakari, ka whakaiti i te piko pumau i raro i te taumaha o ngā pūnaha gantry taumaha, ngā huihuinga whatu, me ngā rūma korehau.
Ko te tikanga, mā te whiriwhiri i tētahi turanga mīhini karāhe kua oti pai te whakaoti mō ngā tono LTPS Array, kei te whakatū ngā kaihangarau i tētahi turanga e pumau ana ki te wera, e marino ana te oro, ā, e pakari ana te hanganga. Kāore e taea te whiriwhiri i tēnei tokotoru o ngā āhuatanga hei whakatutuki i ngā whāinga whakaputa me te hua e hiahiatia ana mō te hanga whakaaturanga LTPS hou.
Te Tino Pai o te Hangarau mai i te Taiao
Ko te hua whakamutunga—te turanga mīhini karāhe—he tino rerekē i te kōhatu taratara. He mahi toi tēnei o te ine ine, he maha ngā wā ka oti ki ngā taunga i inehia i roto i te awhe iti-micron, i raro iho rānei i te-micron. Ka whakamahia ngā tikanga motuhake hei whakarite kia kore e pāngia te karāhe e te ahotea, ā, kia tino papatahi. Mā tēnei rauemi taiao tino pai rawa atu ka whakaratohia te papa tohutoro whakamutunga hei whakataurite i ngā whakaritenga miihini me ngā whakaritenga whatu katoa e whai ake nei.
Mō ngā kaihanga taputapu LTPS, mā te whakaurunga o te karāhe tino tika ka taea e ā rātou mīhini te mahi tonu i te mahi tino pai, ka puta he hua teitei ake me ngā whakaaturanga kounga pai ake mō te mākete kaihoko. He tohu tēnei i te meka e hiahiatia ana te tino tika e te hangarau, ko te titiro ki te rauemi taiao tino pumau o te ao te otinga tino pono.
