TFT stands rau nyias-zaj duab xis transistor thiab yog siv nrog LCD los txhim kho cov duab zoo dua cov laus cov duab yees. Txhua pixel ntawm TFT LCD muaj nws tus kheej transistor ntawm lub iav nws tus kheej, uas muaj kev tswj ntau dua ntawm cov duab thiab xim uas nws renders.
TFT tseem yog cov ntawv luv rau lwm cov ntsiab lus suav nrog lub sijhawm los ntawm kev sib kis, ntawv kho cov ntawv xeem, Trinitron ca raj, thiab cov ntaub ntawv tsis tseem ceeb hloov pauv raws tu qauv.
TFT Cov txiaj ntsig thiab siv
Vim tias cov transistors hauv TFT LCD npo me me, thev naus laus zis muab cov txiaj ntsig ntxiv ntawm kev xav tau lub zog tsawg dua. Txawm li cas los xij, thaum TFT LCDs tuaj yeem xa cov duab ntse, lawv kuj zoo li muab cov duab pom tsis zoo. Qhov tshwm sim yog tias TFT LCDs zoo tshaj plaws thaum saib lub taub hau, tab sis saib cov duab ntawm sab feem ntau nyuaj.
TFT LCDs muaj nyob rau ntawm cov xov tooj qis kawg nrog rau cov xov tooj ntawm tes yooj yim. Cov thev naus laus zis kuj tseem siv rau hauv TVs, handheld video game systems, computer saib, thiab GPS navigation systems.
TFT Qhia Ua Haujlwm Li Cas?
Tag nrho cov pixels ntawm TFT npo tau teeb tsa hauv kab-thiab-kem hom, thiab txhua pixel txuas nrog amorphous silicon transistor uas so ncaj qha rau ntawm lub iav vaj huam sib luag. Qhov no tso cai rau txhua tus pixel kom tau txais tus nqi thiab kom them tus nqi khaws cia txawm tias lub vijtsam rov kho dua los tsim cov duab tshiab.
Nrog hom kev teeb tsa no, lub xeev ntawm ib qho pixel tshwj xeeb tau ua haujlwm ruaj khov txawm tias siv lwm pixels. Qhov no yog vim li cas TFT LCDs suav hais tias yog cov khoom siv matrix (raws li qhov tsis zoo rau cov lus qhia tsis zoo).
Newer Screen Technologies
Ntau lub tuam txhab smartphone siv IPS-LCD (Super LCD), uas muab cov duab pom dav dua thiab cov xim nplua nuj, tab sis cov xov tooj tshiab muaj cov lus qhia uas siv OLED lossis Super-AMOLED thev naus laus zis. Piv txwv li, Samsung's flagship smartphones khav theeb OLED panels, thaum feem ntau ntawm Apple's iPhones thiab iPads tuaj nruab nrog IPS-LCD. Super LCD thiab Super-AMOLED muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, tab sis lawv ob leeg deb tshaj qhov muaj peev xwm ntawm TFT LCD thev naus laus zis.
