Hauv kev ua neej txhua hnub thiab kev ua haujlwm, peb nquag ntsib ntau hom kua siv lead ua kua (LCDs). Txawm hais tias nws yog ntawm lub xov tooj ntawm tes, TV, cov khoom siv me me, lub tshuab xam zauv, lossis lub tshuab cua txias cua sov, LCD thev naus laus zis tau siv dav hauv ntau qhov chaw. Nrog rau ntau yam ntawm cov ntxaij vab tshaus muaj, nws muaj peev xwm feem ntau nyuaj kom paub qhov txawv ntawm lawv. Feem ntau, txawm li cas los xij, lawv tuaj yeem muab faib ua ntau hom, xws li ntu code LCDs, dot matrix cov ntxaij vab tshaus, TFT LCDs, OLEDs, LEDs, IPS, thiab ntau dua. Hauv qab no, peb luv luv qhia qee yam ntawm cov hom loj.
Segment Code LCD
Segment code LCDs tau tsim thawj zaug hauv Nyij Pooj thiab qhia rau Tuam Tshoj hauv xyoo 1980s. Lawv feem ntau yog siv los hloov LED cov raj (sib npaug ntawm 7 ntu los tso saib cov lej 0-9) thiab feem ntau pom muaj nyob hauv cov khoom siv xws li lub laij lej thiab moos. Lawv cov ntsiab lus tso saib yog qhov yooj yim. Lawv kuj raug hu ua ntu-hom LCDs, me me-loj LCDs, 8-cim cov ntxaij vab tshaus, lossis qauv-hom LCDs.
Dot Matrix Screen
Dot matrix cov ntxaij vab tshaus tuaj yeem muab faib ua LCD dot matrix thiab LED dot matrix hom. Cias muab tso, lawv muaj ib daim phiaj ntawm cov ntsiab lus (pixels) teem nyob rau hauv ib tug matrix los ua ib tug zaub cheeb tsam. Piv txwv li, ib qho 12864 LCD npo yog hais txog ib qho screen module nrog 128 kab rov tav cov ntsiab lus thiab 64 ntsug cov ntsiab lus.
TFT LCD
TFT yog ib hom LCD thiab ua lub hauv paus ntawm cov kua siv lead ua kua niaj hnub siv tshuab. Ntau lub xov tooj ntawm tes thaum ntxov siv hom kev tshuaj ntsuam no, uas tseem poob rau hauv pawg dot matrix thiab hais txog pixel thiab xim kev ua haujlwm. Xim qhov tob yog qhov ntsuas tseem ceeb rau kev ntsuas cov khoom zoo, nrog rau cov qauv zoo xws li 256 xim, 4096 xim, 64K (65,536) xim, thiab ntau dua xws li 260K xim. Cov ntsiab lus pom feem ntau muab faib ua peb pawg: cov ntawv nyeem, cov duab yooj yim (xws li cov cim lossis cov duab tas luav), thiab cov duab zoo nkauj. Cov neeg siv uas xav tau ntau dua rau cov duab zoo feem ntau xaiv rau 64K lossis siab dua xim qhov tob.
LED Screen
LED cov ntxaij vab tshaus yog qhov ncaj ncaj-lawv muaj ntau lub teeb ci LED tsim lub vaj huam sib luag, feem ntau siv rau sab nraum zoov billboards thiab cov ntaub ntawv qhia.
OLED
OLED cov ntxaij vab tshaus siv tus kheej-emissive pixel thev naus laus zis los tsim cov duab. Raws li cov qauv teeb pom kev zoo, OLED yog siab dua li LCD. Tsis tas li ntawd, OLED cov ntxaij vab tshaus tuaj yeem ua thinner, uas yuav pab txo qhov tuab ntawm cov khoom siv.
Zuag qhia tag nrho, cov kua siv lead ua kua tuaj yeem muab faib ua ob pawg loj: LCD thiab OLED. Ob hom no sib txawv hauv lawv cov teeb pom kev zoo: LCDs cia siab rau sab nraud backlighting, thaum OLEDs yog tus kheej-emissive. Raws li cov txheej txheem thev naus laus zis tam sim no, ob hom zoo li yuav txuas ntxiv ua ke kom tau raws li ntau tus neeg siv xav tau rau kev ua haujlwm xim thiab daim ntawv thov scenarios.
