Dab tsi yog 4 Hom Kev Pom Zoo?

Taw qhia

Cov duab yog ib qho tseem ceeb ntawm peb lub neej niaj hnub. Txawm hais tias peb tab tom saib yeeb yaj kiab hauv peb lub TV, siv peb lub xov tooj smartphone, lossis tshawb xyuas cov khoom lag luam hauv khw, cov lus qhia yog thawj txoj hauv kev uas peb cuam tshuam nrog lub ntiaj teb. Raws li thev naus laus zis tau dhau los, yog li muaj cov hom kev qhia muaj rau peb. Hauv tsab xov xwm no, peb yuav tshawb txog plaub hom kev qhia thiab lawv siv.

CRT Zaub **

** Cathode Ray Tube (CRT) Qhiayog thawj hom kev qhia siv hauv TV thiab computer saib. Tam sim no lawv feem ntau tsis siv lawm, hloov los ntawm cov thev naus laus zis tshiab xws li LCD thiab LED zaub. CRT zaub ua haujlwm los ntawm kev tua hluav taws xob ntawm lub vijtsam phosphor-coated. Lub nqaj yog ces tswj los ntawm magnetic teb, uas tsim cov duab peb pom ntawm qhov screen.

CRT cov lus qhia tau loj thiab hnyav, tab sis lawv muaj ntau qhov zoo dua lwm hom kev qhia. Lawv muab qhov sib piv ntau dua thiab cov nqi hloov tshiab sai dua, uas ua rau lawv zoo tagnrho rau kev ua si thiab lwm yam kev ua haujlwm siab. Txawm li cas los xij, lawv kuj tau siv lub zog ntau dua thiab tawm cua sov ntau dua li lwm hom kev qhia.

LCD zaub **

** Ua kua Crystal Display (LCD) DisplaysTam sim no yog hom zaub tshaj plaws uas siv hauv TV thiab computer saib. LCD tso saib ua haujlwm los ntawm kev siv cov array ntawm cov kua siv lead ua kua uas yog siv los ntawm lub chaw hluav taws xob los tswj cov teeb pom kev zoo uas dhau los. Lub teeb yog lim los ntawm cov xim lim, uas tsim cov duab peb pom ntawm qhov screen.

Cov duab LCD yog nyias thiab sib zog dua li cov duab CRT, thiab lawv siv zog tsawg dua. Lawv kuj muaj lub neej ntev dua thiab tsis tshua muaj kev kub hnyiab, qhov tshwm sim uas cov duab zoo li qub raug hlawv mus tas li rau hauv qhov screen. Txawm li cas los xij, lawv tuaj yeem raug kev txom nyem los ntawm kev khaws cov duab, qhov twg faint tom qab ntawm cov ntsiab lus uas tau tshwm sim yav dhau los tseem nyob ntawm qhov screen.

LED zaub **

** Lub teeb Emitting Diode (LED) Qhiayog ib hom LCD zaub uas siv LEDs es tsis txhob fluorescent teeb los muab backlight. Lawv muab ntau qhov zoo dua li cov duab LCD, suav nrog qhov sib piv zoo dua thiab qhov dav xim gamut. Lawv kuj siv hluav taws xob tsawg thiab tso cua sov tsawg, ua rau lawv siv zog ntau dua.

LED zaub yog nyias thiab sib zog dua li cov khoom siv LCD thiab muaj lub neej ntev dua. Lawv kuj muaj peev xwm nthuav tawm cov ntsiab lus ntawm cov kev daws teeb meem siab dua thiab cov nqi tshiab. Txawm li cas los xij, lawv feem ntau kim dua li cov khoom siv LCD.

OLED zaub **

** Organic Light Emitting Diode (OLED) Qhiatseem yog ib qho tshiab thev naus laus zis, tab sis lawv tau txais kev nyiam sai sai. OLED qhia ua haujlwm los ntawm kev siv cov txheej txheem ntawm cov organic molecules uas ci ntsa iab thaum hluav taws xob dhau los ntawm lawv. Qhov no tshem tawm qhov xav tau rau backlighting, tso cai rau ultra-thin zaub.

OLED cov lus qhia muaj ntau yam zoo dua lwm hom kev qhia. Lawv muaj qhov sib piv tsis kawg, txhais tau tias lawv tuaj yeem tso cov xim dub tiag tiag thiab cov xim dawb dua li lwm hom kev qhia. Lawv kuj muaj lub sij hawm teb sai dua thiab pom dav dua. Txawm li cas los xij, lawv feem ntau kim dua lwm hom kev qhia thiab tuaj yeem raug kev txom nyem los ntawm kev tshuaj ntsuam hlawv-hauv.

Xaus

Hauv kev xaus, cov lus pom tau los ntev txij li hnub ntawm CRT zaub. Niaj hnub no, muaj plaub hom kev qhia: CRT, LCD, LED, thiab OLED. Txhua hom zaub muaj nws tus kheej lub zog thiab qhov tsis muaj zog, thiab kev xaiv ntawm kev siv yog nyob ntawm lub hom phiaj thiab kev siv nyiaj txiag. Raws li thev naus laus zis txuas ntxiv mus, peb tuaj yeem cia siab tias yuav pom ntau hom kev nthuav qhia yav tom ntej.
