A ndinoiitawo huru ndiyo ano yezvisikwa Indaneti, zvinogona kubatsira pamwe vasanangurwa. Zvinokwanisika kufunga zvakasiyana-siyana yokutevedzera, rondedzero uye mashoko kwavari. Izvi zvichaita kurudzira nani kwauri nezvechisarudzo: design, mutengo nezvimwe parameters. The Zvakanyanya Kunaka Panguva Yepamuviri musiyano wezvinyorwa pamusoro modernity - unhu terevhizheni uye terevhizheni digitaalinen. Kubatana uku kuchaita kuti kuona mafirimu uye mapurogiramu panokwanisika sezvinobvira. Munyika mune vanenge 130 makambani zvinobatanidzwa kugadzirwa materevhizheni, pakati pavo pane uye mudzimba vagadziri. Uye vose vari kunetseka chekunatsiridza zvigadzirwa kuti tiwane kuvimba yevatengi. Unosarudza TV? Ndezvipi zviri nani? Funga zvaunogona kusarudza.

Ndeupi TV zviri nani - LCD kana "yeplasma"?

Saka, unofanira kunzwisisa parameters chidzitiro. On Kutengeswa ndeizvi:

- fungidziro;

- akatungamirira, ndivo zvakare LEDs - TV;

- yeplasma;

- Liquid mechanical vanoratidza (LCD).

Akatungamirira-TV

Kusiyana LEDs - TV uye LCD backlighting zvemichina iri. In kugadzirwa ari LEDs ari LEDs kushandiswa, sezvo iri mvura sekristaro - fluorescent rambi. Izvi zvakare chikuru mukana wokutanga, kureva LEDs. Vanokwanisa kuratidza zvakawanda mavara pane LCD TVs. Munguva LEDs, pane zvimwe zvinokosha zvakwakanakira: vava wakawondereiko kudai mazuva ose, bikai magetsi zvishoma kwahwo uye musiyano nani pane LCD. The zvikuru drawback TV - ndiwo mutengo wayo, izvo zviri yepamusoro. Asi nokuzvisarudzira nayo muimba yokutandarira, haugoni kuwana zvakakwana kuti kutarira mufananidzo yepamusoro. Asi mumamiriro ezvinhu akadaro mubvunzo zvikuru richikoshawo: "? Chii chakaita-TV nani kutenga" Kana ukaverenga nevatengi wongororo paIndaneti, tinogona kuona kuti pagadzirwe dzakakurumbira yemashoko zvinotevera makambani: kuti LG, Samsung, Toshiba, Philips, Sony, Supra uye Akai. Sarudzo ndeyako.

LCD TV

Chii LCD chidzitiro? chizvaro ichi rinoumbwa Dots. zvinhu izvi (Dots) vanonzi pixels. A Pixel - ichi Sub-pixels rutsvuku, girini uye zvitema mavara. Mukati zvinhu zviri emura crystals, kuchinja pachake urongwa kwayo electric munda. Nokuti chizvaro muri backlight. Kana uchifamba crystals kana chinogumbura kana kuparadzira chiedza kubva nemwenje izvi. Mwenje yakawanda simba, nani ruvara, asi simba, ukuwo, kumusoro. TVs kwakadaro zvinokwezva vatengi mukana wekuti mutengo. payakaipira izvi zvinosanganisira rakamanikana kuona angled. Asi pane pluses: kwahwo uye musiyano zvinokosheswa zvakasiyana uye kuvimba TV womuenzaniso. Panguva idzi, zvakakodzera kuteerera kana kutenga chinhu LCD. A chinokosha anobatsirwei kudekara TVs dzakadaro. Somugumisiro, vanogona aiturikwa porusvingo. Asi kuti kuona pachena izvo TV zviri nani, LCD kana "yeplasma", funga mumwe yeplasma TV.

"Plasma"

Plasma chidzitiro - ndiko chizvaro, asi achiumbwa geometric masero. Masero vakazadzwa xenon kana neon. Panguva yakadururwa vanobatwawo Magetsi, gasi rive yeplasma uye inongorira chiedza ultraviolet. On muchitokisi pamadziro zvemapuranga chaiwo sezvamunoita, uye kubatana mwaranzi, zvichienderana Kuronga layer tawana achida ruvara. Kana voltage riri kumusoro, sero yakavhenekerwa yakajeka. Nokusanganisa chikuru Mavara yaunganidzwa zvakasiyana kwerima guru. Chifananidzo chidzitiro kuti chakaumbwa wemagetsi module, kuti voltage kuzvidzora oscillator. Mukuru ndinoiitawo - "yeplasma" katatu yakajeka kupfuura akatungamirira uye LCD. Zviri rakanakira yakafarikana. Saka inguva kusarudza TV zviri nani, LCD kana "yeplasma", nokuti iwe, chii nezvaunokwanisa zvakanakisisa. Zvinofanira kucherechedzwa kuti yeplasma TVs akatanga kubudisa duku kukura achiri ichangopfuura. Accolades vari chigadzirwa makambani Samsung, LG, Panasonic.
