Kodi plasma ndi phindu lanji la plasma?

Opanga makina a plasma apanga patsogolo kwambiri pakugwira ntchito pa mafano a kusiyana kwakukulu. Mwachitsanzo, Panasonic imanena kuti mapepala a plasma omwe amapangidwa amapanga kusiyana kwa 3,000: 1. Makina awa amaletsa mphamvu ku ma pixel kuti apange madontho wakuda kapena amdima. Chifukwa cha njira imeneyi, luso lamakina a plasma limapanga mitundu yakuda yakuda. Koma plasma ndi chiyani?

Gasi yathunthu kapena yaying'ono lero ili ndi dzina lodziwika bwino - plasma. TV ndi teknoloji iyi ili ndi ubwino wambiri. Koma za iwo kanthawi pang'ono. Kuchulukanso kwa zinthu zoipa ndi zomwe zimaperekedwa mu mpweya uwu ndi chimodzimodzi. Pochita kuyaka ndi kupasuka, mu ma laboratory, mapangidwe a plasma amapezeka mu mpweya wokhala ndi magetsi. Kodi plasma ndi iti, anthu adaphunzira mu 1929, pamene asayansi otchuka a ku America - Tonsks ndi Langmuir adalongosola lingaliro limeneli mufilosofi. Panthawi imeneyo, chodabwitsa ichi chinayimilidwa ndi mankhwala otentha kwa madigiri mamiliyoni ambiri. Pa kutentha kotereku, maatomu anaphatikizana ndi mphamvu yodabwitsa, pomwe sangathe kukhalabe okhulupirika. Zotsatira zake, tinthu timene timagawanika timagulu timene timagwiritsa ntchito zigawo zikuluzikulu - magetsi a atomiki ndi nuclei. Ma electron anali ndi mlandu wotsutsa, ndipo nuclei - positive.

Lero, kwa anthu omwe akufuna kutenga TV, funso likubwera: ndi chiyani chabwino: plasma kapena LCD? Palibe amene angapereke yankho losavuta kufunso ili. Kodi pulasitiki ndi chiyani, kudziwa ochepa, koma osati mu LCD-TV si onse akumvetsa. Masitolo akulangiza zomwe zimapindulitsa makamaka kwa iwo, ogulitsa. Pankhaniyi ndi bwino kulankhulana ndi akatswiri, adzakufotokozerani zonse Mapulani ndi minuses za zitsanzo zomwe amaperekedwa.

Pulogalamu yamakono ya plasma mu TV imadziwika ndi makhalidwe otsatirawa:

• Kuchulukitsitsa ndi chiwerengero cha ma electron omasuka pa unit volume;

• Mlingo wa ionization ndi chiŵerengero cha chiwerengero cha ionized particles ku chiwerengero chawo chonse;

• Kusadziletsa. Plasma ndi woyendetsa bwino, ndipo malo amenewa ndi ofunika kwambiri. Chifukwa cha khalidweli, plasma imawunikira magetsi onse.

Ubwino
Ma TV a Plasma ndi awa:

• Chithunzi chophwanyika chaching'ono;

• Zokongola ndi zoyambirira;

• Makwinya akuluakulu;

• Palibe chowombera kwathunthu;

• Ma TV a Plasma sagwiritsa ntchito magetsi ndi magetsi, popeza alibe magetsi amphamvu a anode voltage ndi chipangizo chojambulira;

• Chophimbacho sichikopa fumbi kumtunda;

• Kusakhala ndi X-ray;

• Ma TV a Plasma alibe vuto la chidziwitso, kuganizira ndi kulumikizana;

• Kuwona ngodya pafupifupi madigiri 160;

• Plasma imawonetsera chisankho chomwecho monga njira yopititsira;

• Mapeto a ma TV amenewa ndi pafupi zaka khumi ndi zisanu ndi ziwiri.

Anthu ataphunzira kuti plasma ndi yotani, makampani opanga makina anayamba kukwera pang'onopang'ono. Masiku ano, ndi njira zamakono zamagwiritsidwe ntchito zomwe zimagwiritsidwa ntchito m'njira zambiri.
