Momwe ma LCD amagwirira ntchito

Pakadali pano, matekinoloje ambiri amadzimadzi amadzimadzi amatengera matekinoloje atatu a TN, STN, ndi TFT.Choncho, tikambirana mfundo zawo zogwirira ntchito kuchokera ku matekinoloje atatuwa.Ukadaulo wowonetsa makristalo amtundu wa TN ukhoza kunenedwa kuti ndiwofunikira kwambiri pazowonetsera zamadzimadzi, ndipo mitundu ina yowonetsera yamadzimadzi imathanso kunenedwa kuti imakonzedwa bwino ndi mtundu wa TN ngati koyambira.Mofananamo, mfundo yake yoyendetsera ntchito ndi yosavuta kuposa matekinoloje ena.Chonde onani zithunzi pansipa.Chowonetsedwa pachithunzichi ndi chojambula chosavuta cha TN liquid crystal display, kuphatikizapo polarizers molunjika ndi yopingasa, filimu yoyanjanitsa yokhala ndi ma grooves abwino, zinthu za crystal yamadzimadzi, ndi gawo lapansi lagalasi loyendetsa.Mfundo yachitukuko ndikuti zinthu zamadzimadzi zamadzimadzi zimayikidwa pakati pa magalasi awiri owoneka bwino okhala ndi polarizer yosunthika yomwe imamangiriridwa ku optical axis, ndipo mamolekyu amadzimadzi amadzimadzi amasinthidwa motsatana malinga ndi momwe ma grooves abwino amayendera.Ngati munda wamagetsi sunapangidwe, kuwala kudzakhala kosalala.Imalowa kuchokera ku polarizing mbale, imazungulira njira yake yoyendayenda molingana ndi mamolekyu amadzimadzi a crystal, ndiyeno imatuluka mbali inayo.Ngati magalasi awiri opangira magalasi apatsidwa mphamvu, magetsi adzapangidwa pakati pa zidutswa ziwiri za galasi, zomwe zidzakhudza kuyanjanitsa kwa mamolekyu amadzimadzi amadzimadzi pakati pawo, zomwe zidzachititsa kuti ndodo za maselo zisokonezeke, ndipo kuwala sikudzakhala. amatha kulowa, potero kutsekereza gwero la kuwala.Kusiyanitsa kwa kuwala ndi mdima komwe kumachitika motere kumatchedwa twisted nematic field effect, kapena TNFE (mokhota nematic field effect) mwachidule.Zowonetsera zamadzimadzi zamadzimadzi zomwe zimagwiritsidwa ntchito pazinthu zamagetsi zimakhala pafupifupi zonse zopangidwa ndi zowonetsera zamadzimadzi zamadzimadzi pogwiritsa ntchito mfundo zopotoka za nematic field effect.Mfundo yowonetsera yamtundu wa STN ndi yofanana.Kusiyana kwake ndikuti mamolekyu amadzimadzi amadzimadzi amtundu wa TN wokhotakhota wa nematic amatembenuza kuwala kwazomwe zikuchitika ndi madigiri 90, pomwe mawonekedwe a STN opotoka kwambiri amazungulira kuwala kwa 180 mpaka 270 madigiri.Tiyenera kufotokozedwa apa kuti mawonekedwe osavuta a TN liquid crystal amadziwonetsera okha ali ndi magawo awiri okha a kuwala ndi mdima (kapena wakuda ndi woyera), ndipo palibe njira yosinthira mtundu.Zowonetsera za STN zamadzimadzi za kristalo zimaphatikizapo mgwirizano pakati pa zida zamadzimadzi za kristalo ndi chodabwitsa cha kusokoneza kwa kuwala, kotero kuti mawonekedwe ake amakhala obiriwira komanso obiriwira.Komabe, ngati fyuluta yamtundu ikuwonjezeredwa ku STN LCD ya monochrome, ndipo pixel iliyonse (pixel) ya matrix owonetsera monochrome imagawidwa m'ma pixel atatu, zosefera zamitundu zimadutsa. wofiira, wobiriwira, ndi buluu, ndiyeno mtundu wa mtundu wamitundu yonse ukhoza kuwonetsedwanso mwa kusintha gawo la mitundu itatu yoyamba.Kuonjezera apo, kukula kwa chinsalu chamtundu wa TN-mtundu wa LCD kumachepetsa kusiyana kwa zenera, koma ndi luso lamakono la STN, likhoza kupanga kusiyana kosiyana.
