Hom Cov Ntsiab Lus Qhia
CRT (Cathode-Ray Tube)
Lub raj cathode-ray (CRT) zaub yog ib hom kev saib xyuas uas siv lub teeb tsom ntawm electrons los kos cov duab ntawm lub vijtsam. Daim duab tuaj yeem tsim los ntawm kev siv phom electron lossis laser, nyob ntawm tus qauv. CRTs yog siv nyob rau hauv TV teeb, lub computer saib, thiab lwm yam khoom siv uas yuav tsum tau video tso zis.
LCD (Crystal Display)
Cov kua siv lead ua kua (LCD) yog lub vaj huam sib luag tiaj tiaj uas siv cov tshuab ua kua siv lead ua los tsim cov duab. Lo lus "kua siv lead ua" yog hais txog txoj hauv kev uas lub teeb dhau los ntawm cov muaju, lossis cov molecules, ntawm cov khoom hu ua nematic kua crystals.
Cov tshuaj no yog tsim los ntawm tus pas nrig molecules uas tuaj yeem ua raws li kev siv hluav taws xob. Thaum tsis muaj hluav taws xob siv, cov molecules yog random oriented thiab lub teeb tsis tuaj yeem dhau los ntawm lawv; Thaum qhov hluav taws xob tau thov, lawv kho lawv tus kheej nrog qhov hluav taws xob thiab tso cai rau lub teeb kom dhau los ntawm lawv. Cov cuab yeej no ua rau nws ua tau rau pixels ntawm lub vijtsam LCD los thaiv lossis xa lub teeb nyob ntawm seb lawv puas tau txais ib qho hluav taws xob lossis lwm qhov.
LED (Lub teeb Emitting Diode)
Lub teeb emitting diode (LED) zaub yog lub vaj huam sib luag tiaj tiaj uas siv lub teeb-emitting diodes (LEDs) ua pixels los tsim cov duab thiab cov ntawv.
Daim ntawv tshaj tawm ntawm LED zaub yog nyias, lub teeb yuag panels ua los ntawm kab thiab kab ntawm LEDs. Cov teeb no tuaj yeem qhib lossis kaw los ntawm kev siv cov qib sib txawv ntawm cov khoom sib txawv txhawm rau tsim cov xim xav tau ntawm txhua qhov chaw pixel. Qhov no tso cai rau kev tswj hwm ntau dua ntawm tus kheej pixels, ua rau muaj kev daws teeb meem siab dua thiab cov duab zoo dua li lwm hom kev qhia, xws li LCDs.
OLED (Organic Light-Emitting Diode)
Ib qho organic teeb-emitting diode (OLED) zaub yog lub vaj huam sib luag tiaj tiaj uas siv cov organic teeb-emitting diodes (OLEDs) ua pixels. Cov thev naus laus zis tso cai rau cov duab sib dua, sib dua nrog qhov sib txawv thiab cov xim raug dua li cov ntxaij vab tshaus LCD. Nws kuj tseem muaj zog ntau dua thiab tuaj yeem ua tau yooj yim lossis pob tshab. OLED cov lus qhia feem ntau yog siv hauv smartphones, ntsiav tshuaj, TVs, laptops, thiab cov koob yees duab digital.
Plasma
Lub plasma zaub yog lub vaj huam sib luag tiaj tiaj uas siv cov hlwb me uas muaj hluav taws xob ionized gases, los yog plasmas. Cov pa roj hauv txhua lub xov tooj yog rhuab mus rau qhov chaw uas nws dhau los ua ionized thiab ci ntsa iab thaum muaj hluav taws xob siv thoob plaws ntawm tes.
Cov thev naus laus zis no yog thawj zaug tsim los ntawm cov kws tshawb fawb ntawm Westinghouse Electric Corporation's Pittsburgh labs hauv xyoo 1964, tab sis nws tsis yog txog xyoo 1972 uas cov khoom lag luam siv tau tau qhia hauv qab lub npe lag luam "Plasma Display Panel" (PDP). Xyoo 1973, RCA tau tso tawm nws tus kheej version ntawm cov thev naus laus zis no nyob rau hauv lub npe "Chromatron." Los ntawm 1976, tag nrho cov tuam txhab loj hauv TV tau ntxiv cov tshuaj plasma rau lawv cov khoom lag luam.
Qhov projection
Lub projection zaub yog ib hom ntawm cov vaj huam sib luag tiaj tiaj uas tsim cov duab rau saum npoo es tsis tso rau ntawm qhov screen. Daim duab projected tuaj yeem pom los ntawm ntau lub kaum ntse ntse thiab nyob deb yam tsis muaj kev poob zoo. Cov yeeb yaj kiab yeeb yaj kiab yog siv rau cov ntawv thov xws li digital signage, video phab ntsa, thiab hauv tsev ua yeeb yam.
Touchscreen
Lub touchscreen zaub yog lub khoos phis tawj saib uas siv cov tswv yim kov, feem ntau teb rau tib neeg tus ntiv tes lossis lub ntsej muag stylus. Touchscreens yog ib qho ntawm cov khoom siv nqa tau yooj yim, xws li smartphones thiab ntsiav tshuaj, tab sis lawv kuj tau siv hauv kev sib tham sib kiosks, taw tes ntawm kev muag khoom, thiab kev tswj vaj huam sib luag.
Lub touchscreen tso cai rau cov neeg siv sib cuam tshuam ncaj qha nrog qhov tshwm sim ntawm qhov screen los ntawm kev kov nws tsis yog siv nas lossis keyboard. Qhov no ua rau touchscreens zoo tagnrho rau kev suav xov tooj ntawm tes vim tias cov neeg siv tuaj yeem nkag mus rau cov ntaub ntawv sai sai yam tsis tas yuav rub lawv txhais tes tawm ntawm lub cuab yeej.
VFD (Nqus fluorescent zaub)
VFD zaub yog ib hom vaj huam sib luag vaj huam sib luag uas siv cov array ntawm txias-cathode fluorescent teeb (CCFLs) los teeb lub vijtsam. Lub VFD acronym stands rau "nqus fluorescent zaub" thiab yog thawj coined los ntawm Philips nyob rau hauv 1962 thaum nws qhia thawj cov khoom siv no. Niaj hnub no, lo lus hais txog txhua lub vaj huam sib luag tiaj tiaj uas siv cov thev naus laus zis no.
Hauv kev sib piv nrog cov kua siv lead ua kua, uas yog backlit nrog lub teeb dawb los ntawm lub teeb lossis LED, VFDs siv liab, ntsuab, thiab xiav phosphors ntawm txhua pixel los tsim cov duab xim. Qhov no tso cai rau lawv nyias dua li LCDs thaum tseem muab cov kev daws teeb meem siab thiab ci ntsa iab piv rau cov qauv CRT saib.
