Hauv lub neej txhua hnub thiab hauv kev ua haujlwm, peb feem ntau ntsib ntau hom kua siv lead ua kua (LCDs). Txawm hais tias nws yog nyob rau ntawm xov tooj ntawm tes, TV, cov khoom siv me me, lub tshuab xam zauv, lossis lub tshuab cua txias thermostats, LCD thev naus laus zis tau raug siv dav hauv ntau qhov chaw. Nrog ntau hom ntxaij vab tshaus muaj, nws feem ntau tuaj yeem nyuaj rau qhov sib txawv ntawm lawv. Txawm li cas los xij, feem ntau, lawv tuaj yeem muab faib ua ntau hom tseem ceeb, xws li segment code LCDs, dot matrix screens, TFT LCDs, OLEDs, LEDs, IPS, thiab ntau ntxiv. Hauv qab no, peb luv luv qhia qee hom tseem ceeb.
Segment Code LCD
Cov lej lej LCDs tau tsim thawj zaug hauv Nyiv Pooj thiab tau qhia rau Suav teb xyoo 1980. Lawv feem ntau yog siv los hloov cov raj LED digital (muaj 7 ntu los tso saib cov lej 0-9) thiab feem ntau pom muaj nyob rau hauv cov khoom siv xws li lub tshuab xam zauv thiab moos. Lawv cov ntsiab lus tso saib yooj yim heev. Lawv kuj raug xa mus rau cov lej lej LCDs, cov lej LCDs me me, cov ntxaij vab tshaus 8-cim, lossis cov lej LCDs.
Dot Matrix Screen
Cov ntxaij vab tshaus dot matrix muaj peev xwm muab faib ua LCD dot matrix thiab LED dot matrix hom. Hauv lwm lo lus, lawv muaj cov grid ntawm cov ntsiab lus (pixels) teeb tsa hauv matrix los tsim thaj chaw tso saib. Piv txwv li, ib qho screen LCD 12864 feem ntau yog hais txog ib qho module tso saib nrog 128 kab rov tav thiab 64 ntsug.
TFT-LCD
TFT yog ib hom LCD thiab ua lub hauv paus ntawm cov thev naus laus zis niaj hnub no. Ntau lub xov tooj ntawm tes thaum ntxov siv hom screen no, uas kuj poob rau hauv qeb dot matrix thiab hais txog pixel thiab kev ua tau zoo ntawm xim. Qhov tob ntawm xim yog qhov tseem ceeb rau kev ntsuam xyuas qhov zoo ntawm qhov screen, nrog rau cov qauv ib txwm muaj xws li 256 xim, 4096 xim, 64K (65,536) xim, thiab txawm tias siab dua xws li 260K xim. Cov ntsiab lus ntawm qhov screen feem ntau muab faib ua peb pawg: cov ntawv nyeem yooj yim, cov duab yooj yim (xws li cov cim lossis cov duab kos duab), thiab cov duab zoo li duab. Cov neeg siv uas muaj kev xav tau ntau dua rau qhov zoo ntawm daim duab feem ntau xaiv rau qhov tob ntawm xim 64K lossis siab dua.
LED Screen
Cov ntxaij vab tshaus LED yog qhov yooj yim heev - lawv muaj ntau lub teeb LED tsim cov vaj huam sib luag zaub, feem ntau siv rau hauv cov ntawv tshaj tawm sab nraum zoov thiab cov ntaub ntawv qhia.
OLED
Cov ntxaij vab tshaus OLED siv cov thev naus laus zis pixel uas tso tawm tus kheej los tsim cov duab. Hais txog cov ntsiab cai teeb pom kev zoo, OLED yog qib siab dua li LCD. Tsis tas li ntawd, cov ntxaij vab tshaus OLED tuaj yeem ua kom nyias dua, uas pab txo qhov tuab ntawm cov khoom siv.
Zuag qhia tag nrho, cov ntxaij vab tshaus siv lead ua kua muaj peev xwm muab faib ua ob pawg tseem ceeb: LCD thiab OLED. Ob hom no sib txawv ntawm lawv cov txheej txheem teeb pom kev zoo: LCDs vam khom lub teeb pom kev sab nraud, thaum OLEDs yog cov uas tso tawm tus kheej. Raws li cov qauv thev naus laus zis tam sim no, ob hom no yuav txuas ntxiv mus ua ke kom tau raws li ntau yam kev xav tau ntawm cov neeg siv rau kev ua haujlwm xim thiab cov xwm txheej ntawm daim ntawv thov.
