Kei muri i ia mata o ngā taputapu e taunekeneke ana tātou i ia rā—pērā i ngā waea pūkoro, ngā rorohiko, me ngā mataaratanga atamai—he hangarau matua nui: ko te TFT. Ahakoa te āhua tauhou, ko te "rangatira matua" tēnei e āhei ai ngā whakaaturanga hou ki te whakaatu i ngā whakaahua mārama, maeneene hoki. Nō reira, he aha rawa te TFT i roto i ngā mata LCD TFT? He aha te momo makutu kāore i te tino mōhiotia?
I. Te Whakamāramatanga Matua o te TFT: Te Whakaritenga Tika o ngā Miriona "Pānahi Makaro" i runga i te Mata
Ko te TFT, he whakarāpopototanga mō te Thin-Film Transistor, e mōhiotia ana ko te angiangi-kiriata transistor. Ka taea e koe te whakaaro he pana hiko tino iti i runga i te mata. Ko te mea nui ko te mea e kiia nei e tātou ko te TFT kāore e noho motuhake. I roto i ia mea e kiia nei ko te "mata TFT" (hei tauira, TFT-LCD), he whānuitanga o ngā TFT - kei roto ko ngā miriona, tae atu ki ngā tekau miriona o ēnei pana-iti, kua whakaritea pai ki runga i te papa karāhe. Ko ia TFT e whakahaere motuhake ana, e whakahaere tika ana i te pika kotahi.He kupu whakarite māmā noa iho: Ki te whakaritea ia pika i runga i te mata ki tētahi matapihi, ko te TFT i roto i te mata LCD TFT te pana atamai e whakahaere ana i te nui o te whakatuwheratanga, te kati rānei o taua matapihi. Māna e whakatau tika te nui o te mārama (mai i te waeine whakamārama) ka taea te haere, ā, i te mutunga ka tautuhi i te kanapa me te tae o taua pika. Ko te mahi tahi a ngā TFT maha ka hanga i te ahua katoa e kitea ana e tātou i mua i ō tātou kanohi.
II. Te Pūtake o te Makutu: Mai i te "Kāore" ki te "Hiko," te Mahi Hurihuri a TFT
Ko te makutu tūturu o te TFT kei roto i tana whakatinanatanga o tētahi tikanga whakahaere hou: "te wāhitau matrix hohe." He ao rerekē tēnei i te hangarau "matrix kore mahi" pōrearea i mua i te TFT.
Te raruraru me te kore TFT (Passive Matrix):
He rite ki te whakamahi i tētahi whatunga o ngā rārangi whakawhiti hei whakahaere i ngā pika katoa, he mea koretake, he ngāwari hoki ki te whakawhitiwhiti tohu me te memeha haere.
Te Maramaramatanga me te TFT (Active Matrix):
He pana TFT motuhake tō ia pika. Ina hiahiatia te taraiwa i tētahi pika, ka taea e te tohu whakahaere te kimi me te whakahau tika i te TFT o taua pika kia "tahuri" kia "whakaweto" rānei, me te pupuri tonu i tōna āhua tae noa ki te whakahounga e whai ake nei. Ka puta mai ēnei painga:
Urupare Tere: Ka mahi ngā pana TFT i ngā tere tino tiketike, ka whakaiti nui i te pōuri o ngā nekehanga i roto i ngā whakaahua hihiri i runga i ngā mata LCD TFT.
Te Whakamahinga Hiko Iti: Ka whakaitihia e te āhuatanga pupuri-kāwanatanga te whakapaunga hiko katoa o ngā mata LCD TFT.
III. Te Whakakore i te Pūrākau: TFT ≠ He Momo Mata; Koinei te "Roro Matua" o te Mata
Ko tētahi whakaaro hē noa ko te "he momo mata te TFT." Ko te mea pono, kāore te TFT e tuku mārama, kāore hoki e whakaputa tae. He pūnaha whakahaere matatau tonu—ko te "kōpiti raro" ko te "roro matua" rānei o te mata.
Ko te mata TFT-LCD, e mōhiotia whānuitia ana e tātou, koia te otinga hangarau whakaatu katoa. I tēnei wā, ko te huinga TFT i roto i te mata TFT LCD te kawenga mō te akiaki tika i te whakaritenga o ngā ngota karaihe wai hei whakahaere i te haerenga o te mārama mai i te papamuri. Ahakoa i roto i ngā mata OLED matatau ake, i te wā e hanga ana i ngā hua rahi, teitei rānei te taumira, me whai tonu he huinga TFT hei ara iahiko papa muri hei whakahaere tika i te tukunga mārama o ia pika OLED. Ka taea te kī, me te kore te hangarau TFT, kāore e puta ngā whakaaturanga LCD TFT maeneene, teitei te whakamāramatanga e kitea ana e tātou i ēnei rā.
IV. Te Whanaketanga o te Whānau TFT: Ka Ārahi te Auahatanga Rauemi i ngā Pekenga Mahi
Ko te mahi a te TFT e whakawhirinaki nui ana ki te rauemi semiconductor e whakamahia ana i roto i tana hanga. Ko tōna hītori whanaketanga he haerenga auaha rauemi:
Ko te Amorphous Silicon (a-Si): Ko te hangarau TFT matua tuatahi, he nui ngā painga utu engari he iti te mahi, ā, he uaua ki te whakatutuki i ngā hiahia o te whakaaturanga teitei.
Te Hiraka Kirikiri Mahana-Iti (LTPS): He pikinga o te mahi, me te nekehanga hiko teitei, e āhei ai ngā mata kia pai ake te whakamahi hiko me te aro atu. He whānuitia te whakamahinga i roto i ngā mata LCD me OLED teitei.
Hei whakarāpopototanga, ko te makutu o te TFT i roto i ngā mata LCD TFT kei roto i tōna kaha ki te huri i ngā tohu hiko koretake ki ngā whakaahua matihiko raupapa ka taea te whakahaere me te tika o te taumata pika. Ko te miihini tika, kāore i te mōhiotia, e huna ana i raro i te panera karāhe. Ko te mahi whakarite a ēnei miriona o ngā pana-iti TFT e kawe mai ana i te ao tirohanga matihiko tino mārama, oraora, me te maeneene i mua i ō tātou kanohi. Ko te mārama ki te TFT i roto i ngā mata LCD TFT ko te mārama ki te tūāpapa o te hangarau whakaaturanga hou.
