Materevhizheni emazuva ano uye vatariri havatore nzvimbo yakawanda - vakave vakaonda zvikuru nekuda kwemazuva emitambo. Iye zvino hazviwanzo muimba ipi iwe usingaoni kukosha kwemanheru manheru kusununguka - LCD kana LED TV . Uye kana iwe uchida kuutenga, unogona kunge une mubvunzo pamusoro peLCD kana LED - chii chiri nani? Ngationei izvi.
LCD uye LED TV: musiyano
Chaizvoizvo, musiyano pakati peLCD ne LED hausi muduku. Zvose zviri zviviri zvine chokuita nemichina yezvino, iyo inoshandisa mvura yekristal matrix, inosanganisira mahwendefa maviri. Pakati pavo pane magetsi emvura, kushandura nzvimbo yavo pasi pesimba remagetsi. Paunoshandisa mahwendefa akajeka nemarambi emagetsi, nzvimbo dzakatsvuka uye dzine rima dzinowanikwa pamusoro pematrice. Kana ukashandisa mafiriji emirasi shure kwemasikati, mufananidzo wemavara unooneka pahwindo. Rudzi rwechiedza chekushandisa runoshandiswa - izvi ndizvo chaizvo izvo LCD yakasiyana ne LED.
LCD vatariri kana terevhizheni vanoshandiswa kuburikidza nemagetsi echando cathode fluorescent mwenje yakagadzirirwa mu-cathode-ray tubhu. Iko iri mune matrix horizontally. Muchiitiko ichi, mwenje iri muLCD inoramba iripo, uye nokuti mvura yakachena crystal haigoni kuvhara mhepo yakakwana, pachikanda mutsvuku mhepo tinoona gema guru.
Vatariri ve LED vari chaizvo se subset yeLCD, asi vanoshandisa rudzi rwakasiyana-siyana rwekujekesa-LED. Muchiitiko ichi, ma LED anowanikwa kune rumwe rutivi kana zvakananga muhuwandu hwakawanda. Sezvo zvichikwanisika kuzvidzora, kureva kuti, kuisa rima kana kujekesa dzimwe nzvimbo, kusiyana kwechifananidzo chevatariri ve LED kana TV pane zvinopfuura kudarika kweLCD. Mukuwedzera, zviri nani mavara ekupa: iwe unogona kuona mafirimu ako aunoda uye mapurogiramu pasina kusvibiswa. Nenzira, ruvara rutsvuku runopinda mukati.
Misiyano yakakura pakati peLCD uye LED ndeyekuti kushandiswa kwesimba kwekupedzisira kwakanyanya kuderera. Kutenda kuvhenekeri ye LED, kushandiswa kwesimba kweTV uye chekuona zvakaderedzwa kusvika 40% zvichifananidzwa neLCD. Uye mufananidzo weizvi hautambudzi!
MaTV maTV uye kuenzanisa kweLCD ari muhupamhi. Kushandiswa kwe LEDs kunobvumira kugadzirwa kwe-ultra-thin LED chekucherechedza 2.5 cm yakakura.
Asi kubatsirwa kweLCD zvigadziri kunoramba kuripo kwavo uye kudhura mukuenzanisa ne LED.
