Cov neeg tsim khoom siv thev naus laus zis Plasma tau ua tiav qhov tseem ceeb hauv kev ua haujlwm ntawm cov duab zoo sib xws. Piv txwv li, Panasonic thov tias lawv cov plasma panels ua tiav qhov sib piv ntawm 3000: 1. Cov thev naus laus zis no thaiv cov khoom siv hluav taws xob rau qee cov pixels los ua cov xim dub lossis tsaus nti. Ua tsaug rau txoj haujlwm no, plasma thev naus laus zis tau tsim cov xim dub, tsaus nti. Tab sis plasma yog dab tsi?
Hnub no, tag nrho lossis ib nrab ionized roj muaj lub npe nrov - ntshav ntshav. TV nrog cov thev naus laus zis no muaj ntau qhov zoo. Tab sis txog lawv me ntsis tom qab. Qhov ceev ntawm cov nqi tsis zoo thiab qhov zoo hauv cov roj no yuav luag zoo ib yam. Nyob rau hauv cov txheej txheem ntawm combustion thiab explosions, nyob rau hauv lub laboratory tej yam kev mob, tsim plasma tshwm sim nyob rau hauv ib tug gas nrog ib tug hluav taws xob tawm. Lub plasma yog dab tsi, tib neeg tau kawm rov qab rau xyoo 1929, thaum cov kws tshawb fawb Asmeskas nto moo - Tonsksom thiab Langmuir tau qhia lub tswv yim no rau hauv physics. Thaum lub sij hawm ntawd, qhov tshwm sim no tau sawv cev los ntawm ib yam khoom uas muaj cua sov rau ntau lab degrees. Ntawm qhov kub siab no, cov atoms sib tsoo nrog ib leeg nrog lub zog zoo kawg, thaum lawv tsuas tsis tuaj yeem nyob twj ywm. Thaum muaj kev cuam tshuam, cov khoom tau muab faib ua cov khoom siv -atomic electrons thiab nuclei. Cov electrons tau txais txiaj ntsig nrog cov nqi tsis zoo, thiab cov nuclei nrog cov nqi zoo.
Hnub no, rau cov neeg uas xav khaws lub TV rau lawv tus kheej, cov lus nug tshwm sim - dab tsi zoo dua: ntshav lossis LCD? Tsis muaj leej twg tuaj yeem muab cov lus teb meej rau lo lus nug no. Tsawg tus neeg paub tias plasma yog dab tsi, tab sis tsis yog txhua tus nkag siab LCD TVs. Nyob rau hauv cov khw muag khoom, lawv qhia dab tsi yog qhov zoo nyob rau hauv thawj qhov chaw rau lawv, cov neeg muag khoom. Hauv qhov no, nws yog qhov zoo dua los tiv tauj cov kws tshaj lij, lawv yuav tuaj yeem piav qhia txhua yam rau koj kom meej
pros and cons ntawm cov qauv muab.
Plasma thev naus laus zis hauv TVs yog tus cwj pwm los ntawm cov yam ntxwv hauv qab no:
- ntom yog tus naj npawb ntawm cov electrons dawb rau ib pawg ntawm ib chav tsev;
- degree ntawm ionization yog qhov piv ntawm tus lej ntawm ionized hais rau lawv tag nrho;
- quasi-neutrality. Plasma yog tus neeg xyuas pib zoo, thiab cov cuab yeej no tseem ceeb heev. Vim qhov zoo no, cov plasma thaiv txhua qhov hluav taws xob.
Cov txiaj ntsig ntawmPlasma TVs yog:
- me me thickness tiaj tiaj npo;
- stylish and original design;
- npo loj loj;
- tsis muaj flicker;
- Plasma TVs tsis tsim teeb meem sib nqus thiab hluav taws xob, vim tias lawv tsis muaj qhov hluav taws xob hluav taws xob anode voltage thiab lub cuab yeejswb;
- npo tsis nyiam plua plav rau nws qhov chaw;
- no X-rays;
- Plasma TVs tsis muaj kev sib koom ua ke, tsom lossis teeb meem linearity;
- saib lub kaum sab xis txog 160 degrees;
- plasma qhia tib yam kev daws teeb meem raws li cov tswv yim channel;
- Lub neej ua haujlwm ntawm TVs yog kwv yees li kaum xya xyoo.
Tom qab tib neeg paub tias plasma yog dab tsi, kev lag luam plasma pib txhim kho ntawm tus nqi zoo kawg. Niaj hnub no nws yog ib tug dav siv technology uas yog siv nyob rau hauv ntau txoj kev.
