Kodi TV yowunikira ndi chiyani?

Posachedwa, TV zamakono zatha pang'ono kutha - sizipezeka m'masitolo a zamagetsi, kupatula m'nyumba zina. Koma ma TV omwe ndi opapatiza saganiziridwa kuti ndi apamwamba kwambiri ndipo amagwiritsidwa ntchito paliponse, ndipo mafakitale atsopano ndi matekinoloje apamwamba amapangidwa chaka chilichonse. Chifukwa chake, ogula malonda nthawi zambiri amakumana ndi zovuta kusankha pachisankho chomaliza cha "pepala la buluu" pakati pa kuchuluka kwa zinthu zoperekedwa. Tikukuuzani za TV ya TV ndi ubwino wake.

Kodi luso lamakono ndi liti?

Kawirikawiri kuwala ndikutanthauzira mu Chingerezi, chomwe chimatanthauza "diet-emitting diode". Mawuwo amatembenuzidwa mu Chirasha mophweka - Dzuwa. Ndipo ngati tikulankhula za tanthauzo la TV, ndiye kuti akhoza kutchedwa LCD TV yapamwamba.

Zimadziwika kuti LC ndi teknoloji yogwiritsa ntchito madzi amtundu wa crystal matrix. Zomalizazo zili ndi mbale ziwiri, zomwe zimayikidwa mitsuko yamadzi. Pamene magetsi amagwiritsidwa ntchito, amayamba kusuntha. Koma chifukwa cha nyali zowunikira pamtambo pamwamba pake zimawoneka mdima ndi malo owala. Ndipo mafayilo a mitundu, omwe ali pambuyo pa chivomezi, apange fano lachiwonekera pawindo.

Pogwiritsa ntchito kuwala kwawunikira, ndiye kuti magetsi ambiri amagwiritsidwa ntchito ngati magetsi (mosiyana ndi kuwala kwa LCD, komwe kumagwiritsa ntchito nyali zozizira).

Momwemo, ntchito ya TV yotengera TV imachokera ku kuyang'ana kwa makina amadzi a matrix ndi ma LED.

Ubwino ndi kuipa kwa ma TV a LED

Ma TV ndi teknoloji ya LED ali ndi ubwino wambiri. Mwinamwake, kupindula kwakukulu ndi kugwiritsiridwa ntchito kwa magetsi: malinga ndi akatswiri, mpaka 40% poyerekeza ndi oyang'anitsitsa a LCD , kumene kuwala kumayendetsedwa ndi nyali za fulorosenti.

Kuwonjezera apo, kuyang'ana kwa LED kumangowonongeka mosavuta mkati mwake - Ma LED amatha kupanga mawonekedwe mpaka 3-3.5 masentimita wandiweyani, chifukwa kwenikweni ma LED ali aang'ono kwambiri. Ndipo, ichi si malire. Mwa njira, pali kusiyana mu makonzedwe a ma LED pa TV ma TV, omwe makulidwe a matrix amadalira. Pomwe iwo atayikidwa mofanana pamsewu wa TV, amati kuchokera ku Direct LED. Chifukwa cha ichi, kuunika kwawonekera kumachitika mofanana. Ndithudi mwamvapo za TV zoonda kwambiri za Edge LED. Zomwe maso a Edge LED akuwonekera, zomwe amatchedwa ma dongosolo a LED pafupi ndi chiwonetsero cha chinsalu ndi kugwiritsa ntchito pulogalamu yomweyo. Chifukwa cha ichi, chigawo chokhala ndi mbali ndi chochepa kwambiri - osachepera 3 masentimita! Mwa njira, m'masitolo ogwiritsira ntchito zamagetsi nthawi zambiri mumatchulidwe achitsanzo pali Slim LED - ndi chiyani? Kuwonetseratu kwa ma TV ndi kuchepa kwa thupi ndi 22.3 mm. Kawirikawiri zitsanzo zoterezi zimasowa chithunzi chodziwika bwino pazenera, ngakhale kuti chiri pansi pa galasi.

Phindu lalikulu la ma TV akutha kutchedwa ndi khalidwe labwino la chithunzi. Kupyolera mu kukhazikitsidwa kwa Kuwongolera kufotokozera ndi kudetsedwa kwa malo am'deralo pazithunzi zimakhala zakuda kwambiri. Kujambula kwa mtundu wonse kumakhala koyenerera, kuwala kwa chithunzicho ndi chapamwamba. Mwa njira, mukhoza kuyang'ana mndandanda womwe mumakonda kwambiri pa TV kuchokera kumbali zonse za chipindacho, popanda kuwopa kuti mdimawo ukhale wakuda.

Kujambula kwakukulu kwa makanema a LED ndizo mtengo wake wapatali mu chiŵerengero cha ma TV ndi mitundu ina ya kuunikira. Komabe, akukhulupirira kuti pamene zipangizo zamakono zimapindulitsa, kupanga ma TV ndi LED kuyang'anitsitsa kudzatenga chikhalidwe chachikulu, choncho mtengowo udzachepa.
