Muzera remazuva ano redhijitari, kudiwa kwemasikirini ane simba uye akakwira-resolution akawedzera zvakanyanya. Imwe yemhando dzakajairika dzemapaneru ekuratidzira anoshandiswa mumhando dzakasiyana dzemagetsi ndeye Thin-Film Transistor (TFT) color screen panels. Aya mapaneru anopa zvinokatyamadza zvinoonekwa zvine kumiririra kwemavara, zvichivaita sarudzo inosarudzika yemafoni, mahwendefa, terevhizheni, uye mamwe akawanda maapplication. Muchinyorwa chino, isu tichaongorora muchikamu uye kushanda musimboti weTFT color screen mapaneru kuti tipe kunzwisisa kwakadzama kwekushanda kwavo.
TFT color screen panels inogona kuiswa mumhando mbiri huru zvichienderana nehunyanzvi hunoshandiswa: In-Plane Switching (IPS) uye Twisted Nematic (TN) mapaneru. Mhando mbiri idzi dzine hunhu hwakasiyana uye dzinoshandira zvinangwa zvakasiyana, zvichibatsira mukusiyana kwese muindasitiri yekuratidzira.
Kutanga ne IPS mapaneru, ivo vanozivikanwa nekunaka kwavo kwemavara kubereka uye kureba kwekutarisa angles. Iyi tekinoroji inoshandisa mvura yekristaro kurongeka iyo inobvumira kuti mwenje upfuure pasina kukanganisa, zvichikonzera iwo chaiwo uye akajeka mavara. IPS mapaneru anopa kunyatsojeka kwemavara zvisinei nekona yekutarisa, zvichiita kuti ive sarudzo yakanaka kune nyanzvi dzekutora mifananidzo, graphic vagadziri, uye vanhu vanotsvaga zvemhando yepamusoro zvekuona zviitiko.
Kune rimwe divi, mapaneru eTN ane mukurumbira nekuda kwekukurumidza kupindura nguva uye nemitengo inokwanisika. Iyi tekinoroji inoshandisa makristasi emvura akamonyoroka kana pasina voltage inoiswa, ichivharira mwenje. Kana magetsi akaiswa, makristasi emvura haana kumonyoroka, achibvumira kuti mwenje upfuure nekuburitsa ruvara rwaunoda. TN mapaneru anowanzo shandiswa mune yekupinda-level zvishandiso sezvo ari mutengo-unoshanda uye achipa inogamuchirika kubereka kwemavara kune zvemazuva ese zvikumbiro.
Zvino, ngatinyure mumusimboti wekushanda weTFT color screen mapaneru, tichitarisa paIPS tekinoroji sezvo yakawana mukurumbira wakakura mumakore achangopfuura. Mukati meiyo IPS pani, kune akati wandei akaturikidzana ane basa rekuratidza zvinoonekwa nemazvo uye zvine simba.
Iyo backlight layer, yakaiswa kumashure kwepaneri, inoburitsa mwenje chena inopfuura nepapolarizer. Iyo polarizer inobvumira mwenje chete kutenderera mune imwe nzira kuti ipfuure, zvichikonzera mutsara polarized mwenje. Iri mwenje wepolarized rinobva rasvika kune yekutanga girazi substrate, inozivikanwawo seyeruvara sefa substrate, ine diki tsvuku, girinhi, uye yebhuruu (RGB) mafirita emavara. Imwe neimwe sub-pixel inoenderana neimwe yeaya mavara ekutanga uye inongobvumira iwo chete ruvara kuti ipfuure.
Kutevera iyo color filter substrate ndiyo yemvura yekristaro layer, inoiswa sandwich pakati pemagirazi maviri substrates. Iwo makristasi emvura ari muIPS mapaneru anorongeka akachinjika mumamiriro avo echisikigo. Yechipiri girazi substrate, inozivikanwa seTFT backplane, ine yakatetepa-firimu transistors inoita senge switch yemapikisi ega ega. Pixel yega yega ine sub-pixels anogona kubatika kana kudzima zvichienderana nerudzi rwaunoda.
Kudzora kurongeka kwemakristasi emvura, munda wemagetsi unoiswa kune yakaonda-firimu transistors. Kana voltage ikaiswa, iyo yakatetepa-firimu transistors inoita senge switch inobvumira ikozvino kuyerera nepakati, kurongedza makristasi emvura akamira. Mune ino mamiriro, iyo polarized mwenje inofambiswa kuburikidza nemavara mafirita inomonyoroka 90 madhigirii, ichibvumira kuti ipfuure nepakati yechipiri girazi substrate. Chiedza ichi chakamonyoroka chinobva chasvika papolarizer yepamusoro, yakarongedzwa perpendicularly kusvika kuzasi, zvichikonzera kutenderera kwechiedza chepolarized kudzokera panzvimbo yayo yepakutanga. Kushandurwa uku kunoita kuti chiedza chifambe, chichigadzira ruvara rwaunoda.
Imwe yemabhenefiti akakosha eIPS mapaneru kugona kwavo kupa kunoenderana kubereka kwemavara uye maekona ekuona akafara. Nekuda kwekurongeka kwemakristasi emvura, mapaneru eIPS anobvumira mwenje kuti ufambise zvakaenzana, zvichikonzera mavara akafanana pachiratidziro chose. Pamusoro pezvo, iwo akafara ekuona makona anovimbisa kuti zvinoonekwa zvinoramba zviri zvechokwadi kune yavo yekutanga mavara, kunyangwe kana ichionekwa kubva kune akasiyana maonero.
Mukupedzisa, TFT color screen mapaneru, kunyanya IPS neTN tekinoroji, yakashandura indasitiri yekuratidzira nekuona kwavo kunoshamisa uye kushandiswa kwakasiyana-siyana. IPS mapaneru anokwenenzvera mukurongeka kwemavara uye maekona ekuona akafara, achiaita akanakira hunyanzvi hwekushandisa. TN mapaneru, kune rumwe rutivi, anopa nekukurumidza mhinduro nguva uye mutengo-kubudirira, kugovera kune zvinodiwa nevashandisi vemazuva ese. Nekunzwisisa kupatsanurwa uye musimboti wekushanda weTFT color screen mapaneru, tinogona kuonga kuomesesa kuseri kwemidziyo yave chikamu chakakosha chehupenyu hwedu munguva ino yedhijitari.
