Seri kwese kwese kwezvishandiso zvatinoshandisa zuva nezuva—sefoni, makombiyuta, uye mawachi emazuva ano—kune tekinoroji inokosha: TFT. Zvinganzwika sezvisingazivikanwe, asi "mukuru wemauto" ndiye anoita kuti zviratidziro zvemazuva ano zviratidze mifananidzo yakajeka uye yakatsetseka. Saka, chii chaizvo chinonzi TFT muzviratidziro zveTFT LCD? Ndeapi mashiripiti asingazivikanwe airi nawo?
I. Tsananguro Yechikuru yeTFT: Kurongeka Kwakarurama Kwemamiriyoni e"Microscopic Switches" Pachiratidziro
TFT, muchidimbu cheThin-Film Transistor, inozivikanwa se thin-film transistor. Unogona kuiona seswitch diki kwazvo yemagetsi pachiratidziro. Chinhu chikuru ndechekuti yatinowanzo dana TFT haimbofi iripo yoga. Mukati mese inonzi "TFT screen" (semuenzaniso, TFT-LCD), mune maTFT akawanda-anosanganisira mamiriyoni kana makumi emamiriyoni ema micro-switches aya, akarongwa zvakanaka pagirazi substrate. TFT yega yega inodzora pixel imwe chete thMufananidzo uri nyore: Kana pixel imwe neimwe iri pachiratidziro ichienzaniswa nehwindo, saka TFT iri muchiratidziro cheTFT LCD ndiyo switch yakangwara inodzora mwero wekuvhurwa kana kuvharwa kwehwindo iroro. Inonyatsoona kuti chiedza chakawanda sei (kubva ku backlight module) chinogona kupfuura nepakati, zvichizopedzisira zvaratidza kupenya neruvara rwepikisiki iyoyo. Basa rakabatana reTFT dzisingaverengeki pamwe chete rinoumba mufananidzo wakazara watinoona pamberi pemaziso edu.
II. Chitubu cheMashiripiti: Kubva pa "Passive" kuenda ku "Active," Basa rekuchinja reTFT
Mashiripiti echokwadi eTFT ari mukuziva kwayo nzira yekudzora inochinja-chinja: "active matrix addressing." Iyi inyika yakasiyana netekinoroji ye "passive matrix" isina kunaka yaivepo TFT isati yasvika.
Dambudziko Pasina TFT (Passive Matrix):
Zvainge zvakaita sekushandisa grid yemitsetse inopindirana kudzora mapikiseli ese, izvo zvaisashanda zvakanaka uye zvaiwanzoita kuti pave nechiratidzo checrosstalk uye motion blur.
Uchenjeri Hune TFT (Active Matrix):
Pikseli yega yega ine switch yayo yeTFT. Kana pixel ichida kufambiswa, chiratidzo chekudzora chinogona kuona nekurayira TFT yepikiseli iyoyo kuti "ibatidze" kana "idzime," ichichengetedza mamiriro ayo kusvika yagadziriswazve. Izvi zvinounza mabhenefiti anotevera:
Mhinduro Yekukurumidza: Maswichi eTFT anoshanda nekumhanya kwakanyanya, zvichideredza zvakanyanya kusviba kwemafambiro mumifananidzo inochinja-chinja paTFT LCD screens.
Kushandiswa Kwesimba Rakaderera: Hunhu hwehurumende hunoderedza kushandiswa kwesimba kwese kweTFT LCD screens.
III. Kubvisa Pfungwa Dzenhema: TFT ≠ Rudzi rweScreen; Ndiro "Huropi Hwakadzika" hweScreen
Pfungwa isiriyo yakajairika ndeyekuti "TFT rudzi rwechidzitiro." Muchokwadi, TFT pachayo haiburitse chiedza kana kugadzira ruvara. Chaizvoizvo isystem yekudzora yakaoma - "mukamuri wemukamuri" kana "pfungwa huru" yechidzitiro.
Chidzitiro cheTFT-LCD, chatinonyatsoziva, ndicho mhinduro yakakwana yehunyanzvi hwekuratidza. Muchiitiko ichi, TFT array iri muTFT LCD screen ndiyo ine basa rekutungamira zvakananga kurongeka kwemamorekuru emvura ekristaro kuti idzore kufamba kwechiedza kubva kuchiedza chekumashure. Kunyangwe mune zvidzitiro zveOLED zvepamusoro, pakugadzira zvigadzirwa zvakakura kana zvine resolution yepamusoro, TFT array ichiri kudiwa sedunhu rebackplane kuti idzore nemazvo kubuda kwechiedza kwepixel yega yega yeOLED. Zvinogona kutaurwa kuti pasina tekinoroji yeTFT, zvidzitiro zveTFT LCD zvemhando yepamusoro uye zvakapfava zvatinoona nhasi zvingadai zvisipo.
IV. Kushanduka kwemhuri yeTFT: Kugadzira Zvinhu Zvitsva Kunosimudzira Kubudirira Kwebasa
Kushanda kweTFT kunonyanya kutsamira pazvinhu zvinoshandiswa mukugadzira zvinhu. Nhoroondo yayo yekushanduka-shanduka irwendo rwekuvandudza zvinhu:
Amorphous Silicon (a-Si): Tekinoroji yekutanga yeTFT, ine mabhenefiti makuru emutengo asi kushanda kwayo kushoma, zvichiita kuti zviome kusangana nezvinodiwa zvemadhizaini epamusoro.
Low-Temperature Polycrystalline Silicon (LTPS): Kushanda zvakanaka, ine maerekitironi akawanda, zvichiita kuti masirini ashande zvakanaka uye anogamuchira zviri nani. Anoshandiswa zvakanyanya mumasirini eLCD neOLED emhando yepamusoro.
Muchidimbu, mashiripiti eTFT muma TFT LCD screens ari mukukwanisa kwayo kushandura masaini emagetsi asina kurongeka kuita mifananidzo yedhijitari yakarongeka inogona kudzorwa ne pixel-level chaiyo. Ndiyo mainjiniya asina kurumbidzwa, akanyatsojeka akavanzwa pasi pegirazi. Ibasa rakabatana remamiriyoni aya ema TFT micro-switches anozopedzisira atiunzira nyika yekuona yedhijitari yakajeka, yakajeka, uye yakapfava pamberi pemaziso edu. Kunzwisisa TFT muma TFT LCD screens kunoreva kunzwisisa musimboti wetekinoroji yemazuva ano yekuratidzwa.
