- 4K yog plaub npaug ntawm kev daws teeb meem FullHD, tso cai rau koj saib cov yeeb yaj kiab los ntawm cov koob yees duab tshaj lij.
Lub zog thiab hom emitter
Plasma cov ntxaij vab tshaus muaj qhov ci qis dua li LCD thiab LED TVs. Cov nqi thiab cov yam ntxwv yav dhau los yeej thawj hom TV, tab sis dhau sijhawm, cov thev naus laus zis tshiab tau coj mus. Txawm li cas los xij, ntshav plasma tseem muab cov xim nplua nuj los ntawm kev siv qhov tso tawm ncaj qha ntawm lub teeb ci.
LED TVs tau nruab nrog cov emitters uas muab lub luminous flux txog li 500 cd / m2. Pixel illumination yuav tsum muaj lub teeb muaj zog tom qab lub vijtsam, nyob hauv qab nruab nrab hauv ib qho piv txwv lossis hauv ob kab. Cov qauv TV tshiab kawg tau nruab nrog lub teeb ci diodes, cov nyhuv ntawm cov xim ploj thaum hloov lub kaum sab xis saib raug tshem tawm.
Sib piv cov qauv
