Kawm dab tsi yog meant los ntawm TFT zaub
TFT yog thin-film-transistor, thiab siv LCD los txhim kho cov duab zoo dua qub dua qub. Txhua pixel ntawm TFT LCD nws muaj nws tus kheej transistor ntawm lub khob nws tus kheej, uas muaj kev tswj ntau dua cov duab thiab cov xim uas nws ua haujlwm.
Txij li cov transistors hauv TFT LCD npo me me, lub tshuab muaj kev pab ntxiv ntawm qhov yuav tsum tau muaj zog dua. Txawm li cas los xij, thaum TFT LCDs tuaj yeem xa duab dluab, lawv kuj yuav muaj cov neeg txom nyem uas tsis zoo saib. Qhov no txhais tau hais tias TFT LCDs zoo tshaj plaws thaum pom lub hau-on; nws yog feem ntau nyuaj mus saib cov dluab ntawm sab.
TFT LCDs muaj nyob ntawm qes-kawg smartphones, lossis feature tes, zoo li cov xovtooj ntawm tes . Cov cuab yeej siv kuj yog siv hauv TVs, tuav cov kev ua si video, saib , navigation systems, thiab lwm yam.
Yuav Ua Li Cas TFT LCD Ntxaij Ua Haujlwm?
Tag nrho cov pixels ntawm TFT LCD npo tau teeb tsa nyob rau hauv ib kab thiab kem hom, thiab txhua tus pixel txuas mus rau ib qho hlwv ntawm cov hlab ntsha hauv cov hlab ntim ntawm lub iav.
Cov teeb no tso cai rau txhua tus pixel yuav tsum tau them nyiaj thiab tus nqi yuav tsum khaws cia txawm tias thaum twg qhov screen refreshed los tsim ib cov duab tshiab.
Qhov no txhais li cas yog hais tias lub xeev ntawm ib qho kev pixel yog tseem khom khov kho txawm tias thaum siv lwm cov pixels. Qhov no yog vim li cas TFT LCDs pom tias yog cov txheej txheem matrix (as opposed to passive matrix).
Newer Screen Technologies
Muaj ntau cov tuam txhab smartphone siv IPS-LCD (Super LCD), uas muab cov duab qhib dav dav thiab xim zoo nkauj, tab sis newer cov yeeb yam siv cov duab uas siv OLED los yog Super-AMOLED technology.
Piv txwv, Samsung lub flagship smartphones khwv tau OLED panels, thaum feem ntau ntawm Apple's iPhones thiab iPads tuaj nruab nrog ib IPS-LCD.
Ob leeg yees tau lawv tus kheej thiab cov khoom tab sis yog mais zoo dua TFT LCD tshuab. Saib Super AMOLED vs Super LCD: Dab tsi yog qhov txawv? yog xav paub ntxiv.
