Kuseri kwechidzitiro chese chezvishandiso zvatinodyidzana nazvo zuva nezuva - senge nharembozha, makomputa, uye smartwachi - pane yakakosha tekinoroji: TFT. Zvinogona kunzwika zvisina kujairika, asi i "master commander" inoita kuti zviratidziro zvemazuva ano zviratidze mifananidzo yakajeka uye yakatsetseka. Saka, chii chaizvo chinonzi TFT muTFT LCD skrini? Iro rudzii rwemashiripiti asingazivikanwe yainaro?
I. The Core Tsanangudzo yeTFT: The Precise Coordination yeMamirioni e "Microscopic Switches" paSikirini.
TFT, ipfupi yeThin-Film Transistor, inozivikanwa seyakaonda-firimu transistor. Iwe unogona kuzvifunga sediki diki remagetsi switch pane iyo skrini. Chinhu chakakosha ndechekuti izvo zvatinowanzo daidza kuti TFT hazvimbovepo zvakasarudzika. Mukati mese inonzi "TFT skrini" (semuenzaniso, TFT-LCD), kune yakakura yakawanda yeTFTs-inosanganisira mamirioni kana kunyange makumi emamiriyoni eaya madiki-swichi, akarongwa zvakanaka pane girazi substrate. Imwe neimwe TFT yakazvimiririra uye inonyatso kudzora imwe pixel thEnzaniso yakapfava: Kana pixel yega yega pachiratidziro ichifananidzwa nehwindo, saka TFT iri muTFT LCD skrini ndiyo smart switch inodzora dhigirii iro iro hwindo rinovhurwa kana kuvhara. Iyo inonyatso tarisa kuti ingani mwenje (kubva kubacklight module) inogona kupfuura, pakupedzisira ichitsanangura kupenya uye ruvara rweiyo pixel. Basa rakarongeka remaTFT asingaverengeki pamwe chete anoumba mufananidzo wakazara watinoona pamberi pemeso edu.
II. Kwakabva Mashiripiti: Kubva ku "Passive" kuenda ku "Anoshanda," Basa reRevolutionary reTFT
Iwo echokwadi mashiripiti eTFT ari mukuzadzikiswa kwayo kweshanduko yekudzora nzira: "inoshingaira matrix kugadzirisa." Iyi inyika kunze kweiyo clumsy "passive matrix" tekinoroji yaivepo TFT isati yasvika.
Iyo Dilemma Pasina TFT (Passive Matrix):
Zvakanga zvakaita sekushandisa gidhi yemitsara inopindirana kudzora mapikseli ese, ayo aive asingashande uye aiwanzoita chiratidzo checrosstalk uye kusvibiswa kwekufamba.
Hungwaru Ine TFT (Active Matrix):
Imwe neimwe pixel ine yayo yakatsaurirwa TFT switch. Kana pixel ichida kufambiswa, chiratidzo chekudzora chinogona kunyatso tsvaga uye kuraira iyo pixel's TFT kuti "ibatike" kana "kudzima," ichichengetedza mamiriro ayo kusvika painozorodzwa. Izvi zvinounza zvinotevera zvakanakira:
Mhinduro Yekukurumidza: TFT switch inoshanda nekumhanya kwakanyanya, ichideredza zvakanyanya kubvongodza kwekufamba mumifananidzo ine simba paTFT LCD skrini.
Lower Power Consumption: Iyo nyika-inobata hunhu inoderedza iyo yakazara simba kushandiswa kweTFT LCD skrini.
III. Debunking Iyo Ngano: TFT ≠ Rudzi rweChidzitiro; Ndiyo "Underlying Brain" yeScreen
Imwe pfungwa isiriyo ndeyekuti "TFT imhando yechidzitiro." Muchokwadi, TFT pachayo haibudisi chiedza kana kuburitsa ruvara. Iyo inonyatso dhizaini yekudzora sisitimu - "yepasi pecockpit" kana "pfungwa dzepakati" dzechidzitiro.
Iyo TFT-LCD skrini, iyo yatinonyanya kujaira, ndiyo yakazara kuratidza tekinoroji mhinduro. Muchiitiko ichi, iyo TFT array muTFT LCD skrini ine basa rekunyatso kutyaira kurongeka kwema crystal mamorekuru kudzora mafambiro echiedza kubva kumashure. Kunyangwe mune zvemberi zveOLED skrini, kana uchigadzira yakakura-hukuru kana yakakwirira-resolution zvigadzirwa, TFT array ichiri kudikanwa seyekumashure redunhu kudzora nemazvo kubuda kwechiedza chepikisi imwe neimwe yeOLED. Zvinogona kutaurwa kuti pasina TFT tekinoroji, iyo yakakwirira-tsanangudzo, yakatsetseka TFT LCD inoratidzira yatinoona nhasi ingadai isipo.
IV. Iko Kushanduka kweTFT Mhuri: Material Innovation Inotyaira Kuita Kusvetuka
Kuita kweTFT kunonyanya kutsamira pane semiconductor zvinhu zvinoshandiswa mukugadzira kwayo. Nhoroondo yaro yekushanduka-shanduka rwendo rwekugadzira zvinhu:
Amorphous Silicon (a-Si): Yekutanga yakajairwa TFT tekinoroji, ine zvakakosha mutengo zvakanakira asi kuita kushoma, zvichiita kuti zviome kusangana nepamusoro-yekupedzisira kuratidza zvinodiwa.
Yakaderera-Tembiricha Polycrystalline Silicon (LTPS): Kusvetuka mukuita, ine yakakwira erekitironi kufamba, zvichiita kuti masikirini awedzere simba-anoshanda uye anoteerera. Inoshandiswa zvakanyanya mune yakakwirira-yekupedzisira LCD uye OLED skrini.
Muchidimbu, mashiripiti eTFT muTFT LCD skrini ari mukukwanisa kwayo kushandura masaini emagetsi asina kurongeka kuita mifananidzo yedhijitari yakarongeka inogona kudzorwa nepixel-level chaiyo. Ndiyo mainjiniya asina kuimbwa, akanyatsovigwa pasi pegirazi regirazi. Iro ibasa rakarongeka remamiriyoni aya eTFT micro-swichi izvo zvinozotiunzira zvinoshamisa, yakajeka, uye yakatsetseka yedhijitari inoonekwa nyika pamberi pemeso edu. Kunzwisisa TFT muTFT LCD skrini kunoreva kunzwisisa iyo yekona yemazuva ano tekinoroji yekuratidzira.
