Hauv cov khoom siv hauv tsev niaj hnub xws li TFT-cov ntxaij vab tshaus tau siv ntau heev. Lawv tuaj yeem pom hauv ntau hom khoom siv: khoos phis tawj, xov tooj ntawm tes, ntsiav tshuaj, ATMs, thiab ntau lwm yam khoom siv. Qhov no technology yog dab tsi, dab tsi yog nws zoo? Hauv tsab xov xwm no, peb yuav tshuaj xyuas seb TFT cov ntxaij vab tshaus yog dab tsi, lawv hom thiab qhov zoo.
Thin-film transistor (TFT), uas hauv lus Askiv txhais tau tias nyias-film transistor. Cov ntsiab lus no yog tsim los ntawm cov yeeb yaj kiab nyias nrog lub thickness ntawm 0.1-0.01 microns. Rau cov neeg feem coob, LCD saib yog txuam nrog cov ntxaij vab tshaus hauv TVs, laptops, camcorders, thiab lwm yam. Niaj hnub nimno TFT cov ntxaij vab tshaus yog tus cwj pwm los ntawm kev tsim kho, siab ci, thiab muaj peev xwm ua haujlwm hauv qhov kub thiab txias. Kev siv thev naus laus zis tau piav qhia ua rau nws tuaj yeem txo qhov hnyav, tag nrho qhov ntev thiab lub zog siv ntawm cov khoom siv.
thawj cov kua siv lead ua kua matrices tau tshwm sim hauv xyoo 1972. Txij thaum ntawd los, cov thev naus laus zis no tau hloov zuj zus thiab hloov pauv loj heev. Niaj hnub no muaj ntau hom TFT saib:
- TN TFT - Hom TFT xim npo no (thawj thev naus laus zis nkag mus rau cov kua siv lead ua kua ua lag luam) yog pheej yig. Qhov tsis zoo muaj xws li xim distortion, cov duab tsis sib xws, ci heev thiab pom tau tias "tawg" pixels.
- Super Fine TFT, lub vijtsam TFT no nta lub kaum sab xis saib siab tshaj plaws ntawm 170 degrees, nrog rau kev tsim cov xim siab, lub sijhawm teb ntawm 25ms, cov pixels tuag yog xim dub, thiab yog li tsis pom zoo.
- Super IPS, Advanced SFT - muaj cov duab ci ntsa iab, zoo sib xws, yuav luag tsis muaj xim txawv, nce pom lub kaum ntse ntse, siab cov duab pom tseeb.
- UA-IPS, UA-SFT - muaj theem qis ntawm kev cuam tshuam ntawm cov duab xa mus ntawm qhov sib txawv. Cov lus qhia no ua rau muaj kev txhim kho vaj huam sib luag pob tshab thiab dav xim gamut ntawm qib siab ci ntsa iab.
- MVA, lub ntsiab kom zoo dua ntawm cov thev naus laus zis no yog lub sijhawm tshuaj tiv thaiv tsawg kawg nkaus, nrog rau qib siab ntawm qhov sib txawv. Qhov tsis zoo suav nrog tus nqi siab.
- PVA - ntsug microstructural tso ntawm LCDs.
Kev txhim kho txuas ntxiv ntawm TFT-technologies tau txo qis tus nqi ntawm kev tsim cov khoom zoo li no. Ib qho tseem ceeb hauv kev siv cov matrices nquag hauv kev lag luam tau dhau los ua kev yooj yim ntawm kev tsim khoom. Niaj hnub no, kov npo (TFT) yog qhov qub, thiab nees nkaum xyoo dhau los, nws yog "kim kab txawv". Cov tsos ntawm cov duab kov tau ua ntej los ntawm cov tsos ntawm cov qauv uas muaj peev xwm ua haujlwm nyob rau hauv ib puag ncig hnyav.kev ua haujlwm. Qhov tshwm sim yog kev txhim kho ntawm TFT-saib xyuas, uas ua ke ib qho kev qhia pom cov ntaub ntawv, nrog rau kev nkag mus rau cov ntaub ntawv (keyboard). Lub operability ntawm xws li ib tug system yog muab los ntawm lub serial interface xws li. PIC controllers yog siv los tswj thiab txiav txim siab cov teeb liab ntawm lub sensor, nrog rau kev txwv "thaws", lawv muaj peev xwm muab kev kub ceev, nrog rau qhov tseeb hauv kev txiav txim siab kov cov ntsiab lus.
Nyob rau hauv xaus, cia peb hais tias TFT thev naus laus zis tau yuav luag tag nrho hloov lub raj saib. Niaj hnub no, TFT cov lus tsis yog khoom kim heev, tab sis yog ib qho tshwm sim.
