Kusiyanitsa Pakati pa LCD TV ndi Plasma TV

Ma TV ndi Plasma TV amafanana ndi kunja, koma zimakhala zosiyana mkati

Mu 2015, kupanga Plasma TV kunatha. Komabe, zambiri zimagwiritsidwa ntchito ndikugulitsidwa kumsika wachiwiri. Zotsatira zake, kumvetsetsa momwe TV ikugwirira ntchito ndi momwe ikufananirana ndi TV ya LCD ndi yofunika.

Plasma ndi LCD TV: Zofanana, Koma Zosiyana

Maonekedwe akunja akunyenga kwambiri pa LCD ndi Plasma TV.

Mafilimu a Plasma ndi a LCD ndi ophweka komanso ofooka, ndipo angaphatikizepo zinthu zambiri zomwezo. Mitundu yonse iwiri ikhoza kukhala ndi khoma ndipo ingapereke intaneti ndi kusakanikirana kwapansi , zonse zimapereka njira zofanana zogwirizana, ndipo, zonsezi zimakulolani kuti muwone mapulogalamu a pa TV, mafilimu, ndi zinthu zina pawonekedwe makulidwe ndi zisankho. Komabe, momwe amachitira ndi kusonyeza zithunzi zimenezo ndizosiyana kwambiri.

Momwe Ma TV a Plasma Amagwirira Ntchito

Sayansi ya TV ya Plasma imakhala yosasunthika pa babu la kuwala. Chiwonetsero chomwecho chimapangidwa ndi maselo. Pakati pa selo iliyonse magalasi awiri amagazi amalekanitsidwa ndi kapangidwe kakang'ono kamene kali ndi kapangidwe kake, kachipangizo ka electrode, ndi electrode, yomwe imayikidwa jekeseni ya neon-xenon ndikuyikidwa mu mawonekedwe a plasma panthawi yopanga makina.

Plasma TV ikugwiritsidwa ntchito, mpweya umagwidwa ndi magetsi pamakanthawi ochepa. Gasi yowonongeka imagunda phosphors yofiira, yobiriwira, ndi ya buluu, motero amapanga chithunzi pawonekedwe la Plasma TV. Gulu lirilonse la phosphors wofiira, wobiriwira, ndi la buluu limatchedwa pixel (choyimira chithunzi - munthu wofiira, wobiriwira, ndi buluu phosphors amatchulidwa ngati ma pixelisi apansi) . Popeza ma pixelesi a Plasma TV amapanga kuwala kwawo, amatchulidwa kuti "masomphenya".

Chifukwa cha momwe Plasma TV imagwirira ntchito, ikhoza kukhala yopyapyala kwambiri. Komabe, ngakhale kuti kufunika kwa chithunzi chojambulira chithunzi cha electro TV ndi ma electron chingwe chasankhulidwe cha CRT sichifunikanso, Ma TV a Plasma amagwiritsa ntchito phosphors yotentha kuti apange fano. Zotsatira zake, ma TV a Plasma adakali ndi mavuto ena a CRT TV, monga kutentha kwa dzuwa ndi zithunzi zomwe zimakhala zovuta.

Momwe Ma TV A LCD Amagwira Ntchito

Ma TV a LCD amagwiritsira ntchito zipangizo zamakono kusiyana ndi plasma kusonyeza chithunzi. Zipangidwe za LCD zimapangidwa ndi zigawo ziwiri zowonekera, zomwe zimatchulidwa, ndipo zimagwiritsidwa ntchito pamodzi. Chimodzi mwa zigawozo chimavala ndi polima wapadera omwe amanyamula makina amadzimadzi. Pano pakadutsa kupyolera pamakina, omwe amalola makristasi kuti apitirire kapena kutsegula kuwala kuti apange zithunzi.

Makristalo a LCD samapanga kuwala kwawo, kotero kuwala komwe kumachokera kunja, monga fluorescent (CCFL / HCFL) kapena ma LED akufunika kuti chithunzi chojambulidwa ndi LCD chiwonekere kwa wowonera. Kuyambira mu 2014, pafupifupi TV zonse za LCD zimagwiritsa ntchito zowunikira. Popeza ma crystals a LCD samapanga kuwala kwawo, TV za LCD zimatchulidwa ngati "zosasintha" mawonetsero.

Mosiyana ndi Plasma TV, popeza palibe phosphors yomwe imatuluka, mphamvu zochepa zimagwiritsidwa ntchito komanso kuwala kwa LCD TV kumapanga kutentha pang'ono kuposa Plasma TV. Komanso, chifukwa cha luso lamakono la LCD, palibe ma radiation omwe amachokera pawindo.

ZINTHU ZOFUNIKA Plasma pa LCD

• Chiŵerengero chabwino chosiyana kusiyana ndi luso lopereka wakuda wakuya.
• Kulondola kwa mtundu wa mtundu ndi kusungunuka.
• Kuwongolera kwabwinoko (kuyendetsa pang'onopang'ono kapena popanda kuyendetsa galimoto mofulumira chifukwa cha kugwiritsa ntchito Sub Field Drive Technology ).
• Yang'anani mbali yoyang'ana mbali ndi mbali.

ZINTHU ZOTHANDIZA Plasma vs LCD

• Ma TV a Plasma sali owala ngati ma TV ambiri a LCD. Mafilimu a Plasma amachita bwino mu chipinda chodetsedwa kapena chodetsedwa.
• Pulogalamuyi ikuwonekera kwambiri kuposa ma TV ambiri a LCD. Zowonjezereka zowonongeka - zowonekera pamwamba zimasonyeza zowoneka zowala.
• Mafilimu a Plasma amakhala otentha kwambiri. Komabe, vutoli lachepa kwambiri m'zaka zaposachedwa chifukwa cha kuikidwa kwa "pixel" ndi njira zamakono.
• Mafilimu a Plasma amachititsa kutentha kwambiri ndikugwiritsa ntchito mphamvu zambiri kuposa ma TV a LCD, chifukwa cha kufunika kwa phosphors kupanga mapangidwe.
• Sichitikanso bwino kumtunda wapamwamba.
• Momwemo nthawi yayitali yawonetsera moyo - izi zimakhala choncho. Mapulala oyambirira anali ndi maola 30,000 kapena maola 8 akuwonera tsiku kwa zaka 9, zomwe zinali zochepa kuposa LCD. Komabe, nthawi yowonetsa masewero a pulogalamu yamakono yowonjezera bwino ndipo maola 60,000 otha msinkhu wa moyo amakhala wamba, ndipo ma seti ena amavomereza ngati maola 100,000, chifukwa cha kukonzanso zamakono.

AMAFUNA LCD pa Plasma TV

• Palibe zithunzi zolimbitsa.
• Kutentha kumathamanga.
• Palibe nkhani zogwiritsa ntchito zakutali.
• Kuwala kwa chifaniziro choposa Plasma, chomwe chimapangitsa LCD TV kukhala bwino poyang'ana mu zipinda zowala kwambiri.
• Pulogalamu yapamwamba pa TV zambiri za LCD sichinthu chowoneka bwino kusiyana ndi mawonekedwe a Plasma TV, zomwe zimawoneka kuti sizowoneka bwino.
• Kulemera kolemera (poyerekeza kukula kwazithunzi zofanana) kuposa Plasma.
• Moyo wautali wautali, koma kusiyana kwachepera.
• Kwa 3D, ndi LCD muli ndi kusankha pakati pa mayunitsi omwe amagwiritsira ntchito Active Shutter ndi Passive Magalasi , pamene 3D Plasma TV zimangogwiritsira ntchito dongosolo la Active Shutter Glasses.

ZINTHU ZOTHANDIZA ZA LCD vs Plasma TV:

• Kusiyanitsa kwapadera kwenikweni, osati kutembenuza bwino wakuda wakuda, ngakhale kuwonjezereka kowonjezeredwa kwa kuwala kwa LED kotsekemera kwachepetsanso mpata uwu.
• Izi sizikuyenda bwino (zosuntha zowonongeka mwatsatanetsatane). Komabe, izi zikusintha ndi kukhazikitsidwa kwaposachedwa kwa 120Hz kusinthasintha kwazithunzi ndi kusintha kwa 240Hz mu malo ambiri a LCD, koma izi zingathe kukhala ndi "Opera Opera Sapulo", momwe mafilimu ozikidwa pafilimu amawoneka ngati kanema kanema filimuyi.
• Mng'onoting'ono woyang'ana mbali ndi mbali pambali kuposa Plasma. Pa TV za LCD, zimakhala zachilendo kuona kuwala kwa mtundu kapena kusuntha kwa mtundu pamene mukusunthira malo anu owonetsekerako kumbali imodzi ya malo apakati.
• Ngakhale makanema a LCD sakuvutika ndi kutengeka, ndizotheka kuti ma pixel apadera pa televizioni za LCD akhoza kutentha, kuchititsa madontho ang'onoang'ono, owonekera, akuda kapena oyera kuti awonekere pazenera. Ma pixel payekha sangathe kukonzedwa, sewero lonse liyenera kusinthidwa panthawi imeneyo ngati kutentha kwa pixel kumakukhudzani.

• LCD TV imakhala yotsika mtengo kuposa momwe zilili zofanana (ndi zofanana) Plasma TV, ngakhale kuti izi sizinali zofunikira, pakali pano TV za Plasma zatha.

Chochitika cha 4K

Chinthu china chosonyeza kuti pali kusiyana pakati pa LCD ndi Plasma TV, ndikuti pamene 4K Ultra HD TV imayambitsidwa, opanga TV akupanga kusankha kupanga kokha ma 4K okhala pa TV za LCD, pogwiritsa ntchito LED kutsogolo, ndipo, ngati ali ndi LG ndi Sony, akuphatikizanso 4K m'ma TV pogwiritsa ntchito matelogalamu OLED .

Ngakhale kuti n'zotheka kupanga pulogalamu ya 4K ku Plasma TV, zimakhala zodula kwambiri kuposa momwe zilili pa nsanja ya LCD TV, ndipo, malonda a Plasma TV akupitirizabe kuchepa kwa zaka, opanga TV Plasma adachita bizinesi kuti asamabweretse makasitomala 4K Ultra HD Plasma TV pamsika, yomwe inali chinthu chinanso chimene chinachititsa kuti awonongeke. Mafilimu 4K Ultra HD Plasma omwe anali / amapangidwa ndizomwe amagwiritsa ntchito malonda.

Mfundo Yofunika Kwambiri

Plasma ili ndi malo olemekezeka m'mbiri ya TV monga teknoloji yomwe inayambira njira yopangidwira, TV, ndi mavidiyo omwe adalonjezedwa kuyambira kumayambiriro kwa zaka za m'ma 1950. Zomwe zinapangidwa zaka zoposa 50 zapitazo, zowonjezereka komanso zotchuka zakhala zikuchitika zaka khumi zoyambirira zazaka za zana la 21 koma tsopano zadutsa pa Gadget Heaven chifukwa cha kupita patsogolo kwa luso la TV ndi kuyambitsa ma TV OLED, omwe adatsegula kusiyana kwa ena ubwino umene Plasma TV inapereka.

Kuti mumve zambiri pa LCD ndi Plasma TV, muwerenge kuti: Kodi ndiyenera kugula LCD kapena Plasma TV? .
