Plasma cov lus qhia tau tshwm sim thawj zaug thaum xyoo 1960. Lawv muaj ntau qhov zoo - qhov pom lub kaum ntse ntse dua, cov duab tuab dua, lub vijtsam loj dua thiab pom thaj chaw tiaj.
Cov Lus Qhia
Kauj ruam 1
Txhawm rau xav txog yuav ua li cas ntshav TV ua haujlwm, tsuas yog saib lub teeb roj fluorescent uas ua haujlwm ntawm tib lub hauv paus ntsiab lus. Cov teeb muaj argon lossis lwm cov roj inert, feem ntau cov atoms ntawm cov roj yog cov hluav taws xob nruab nrab, tab sis yog tias qhov hluav taws xob dhau los ntawm nws, muaj hluav taws xob ntau ntawm cov hluav taws xob tua cov roj atoms, uas yuav ua rau poob ntawm a nqi nruab nrab. Raws li qhov tshwm sim, cov pa roj ionizes thiab hloov mus rau hauv cov ntshav muaj conductive.

Hauv cov ntshav no, cov roj ntsha ntim tau hauv cov lus qhia tas mus li hauv kev tshawb nrhiav qhov chaw dawb, sib tsoo nrog cov roj atoms, uas ua rau lawv tawm ntawm cov duab hluav taws xob ultraviolet. Cov photon no tsis tuaj yeem pom tshwj tsis yog tias lawv tau qhia rau phosphor txheej siv sab hauv cov roj fluorescent. Tom qab raug ntaus los ntawm ultraviolet photons, phosphor particles pib emit lawv tus kheej pom photons, uas pom tau rau tib neeg lub qhov muag.

Plasma cov lus qhia siv tib lub hauv paus ntsiab lus, tshwj tsis yog tias lawv siv lub iav laminated kev xaiv tus kheej tsuas yog siv tub luam. Pua pua txhiab tus hlwb them nrog phosphor yog nyob nruab nrab ntawm phab ntsa iav. Cov phosphor no tuaj yeem tawm ntawm lub teeb ntsuab, liab thiab xiav. Lub pob tshab ntog ua rau cov duab hluav taws xob muaj lub ntsej muag muaj nyob rau hauv lub khob sab nraud;

Cov xaum ntawm cov phosphors lossis cov pixels nyob hauv qab hluav taws xob; lawv tau tsim los ntawm cov thawv me me. Hauv qab lawv muaj cov kab ke ntawm chaw nyob electrodes uas nyob ncaj rau lub tso saib, txhua qhov chaw electrode kis tau los ntawm qhov tsis sib xws.
Kauj ruam 5
Kev sib xyaw tshwj xeeb ntawm neon thiab xenon raug txhaj ntawm lub hlwb ua ntej sib khi cov ntshav ntawm lub siab qis; lawv yog cov roj ntsha inert. Txhawm rau ionize lub xovtooj tshwj xeeb, koj yuav tsum tsim qhov hluav taws xob tsis sib txawv ntawm qhov chaw nyob thiab tso saib cov khoom siv hluav taws xob, uas nyob rau sab saud thiab hauv qab ntawm cov xovtooj ntawd tshwj xeeb.
Kauj Ruam 6
Vim qhov voltage no sib txawv, cov pa roj ionizes, emitting cov nqi ntawm cov duab hluav taws xob loj ntev uas ua rau lub ntsej muag ntawm lub hlwb pixel, energizing phosphor, ua rau nws tawm lub teeb. Kev hloov pauv ntawm cov hluav taws xob (uas yog tsim los siv cov kev cai ntsuas) tso cai rau koj hloov qhov sib txawv ntawm cov xim ntawm txhua pixel. Tus txheej txheem no tshwm sim ib txhij nrog ntau pua txhiab tus ntawm cov hlwb pixel, uas tso cai rau koj kom tau txais cov duab zoo.
