Zoo:

  • CRT - TVs nrog cathode ray raj. Hais txog analog technology. Tam sim no kev coj ncaj ncees thiabtechnically dhau lawm. Lawv muaj cov duab convex (tab sis kuj muaj cov tiaj tus), uas distors cov duab.
  • Projection - ua cov duab rau hauv cov duab matte. Lawv muab cov suab zoo heev thiab cov kab pheeb ces kaum loj. RPTV thev naus laus zis muaj qhov projector, npo, suab kaw lus thiab tswj vaj huam sib luag.
  • Pab vaj huam sib luag.
  • Nkauj.
  • Nrog lub vijtsam hloov pauv.

Vaj huam sib luag yog muab faib ua peb hom:

  • LCD lossis HDD. Cov no yog LCD-TVs, qhov twg daim duab muaj ntau lab pixels, thaum cov kua muaju xa tawm lub teeb los ntawm cov teeb. Kev siv hluav taws xob tsawg, kev tsim cov xim zoo nkauj. Kev pab lub neej - los ntawm 50 mus rau 100 txhiab teev.
  • Plasma. Ib qho screen ntawm cov hlwb uas muaj cov pa roj. Tam sim no tsim ib qho hluav taws xob, thiab lub xov tooj ntawm tes pib ci. Kev siv hluav taws xob ntau dua nrog kev nce kab pheeb ces kaum thiab qis dua qhov ci. Kev pab lub neej - 100 txhiab teev.
  • OLED. Cov cuab yeej technology pib hauv 2012. Lub matrix uas muaj diodes xa cov xim dub zoo, muaj qhov ci zoo dua thiab qhov sib txawv vim nws tus kheej-emitting lub teeb los ntawm diodes. Lawv kim heev. Lub tuam txhab tseem ceeb tsim cov TVs yog Samsung thiab LG. Kev pab lub neej - 10 txhiab teev.

  4. Tus nqi dav, ntau yam qauv.
  5. Cov duab ruaj khov hauv txhua lub teeb, ci ntsa iab, sib piv, xim.
  6. Nco ntsoov npaj rauua haujlwm.
  7. Tag nrho hauv ib qho. Raws li lub TV ntse thiab Internet, ntau qhov chaw nres nkoj rau lwm cov khoom siv ntxiv.

  3. Daim duab loj yog nyob ntawm kab pheeb ces kaum ntawm lub vijtsam thiab hloov tsis tau nce lossis nqis.
  4. Qhov siab dua kab pheeb ces kaum - tus nqi siab dua ntawm tus qauv. Yog tias koj piv lub projector thiab TV yog tias koj xav tau kab pheeb ces kaum ntau tshaj 2 meters, ces tus nqi yuav yog qhov tseem ceeb.
  5. Kev pom ntev ua rau pom kev tsis pom kev los ntawm kev tsom lub qhov muag ntawm qhov chaw hluav taws xob ntau dua li qhov pom kev pom.

Ntawm thiab qhov tsis zoo ntawm lub projectors

Ua ntej, lawv txawv ntawm cov duab tso zis thev naus laus zis. Muaj peb lub thev naus laus zis hauv tag nrho:

  1. DLP - yog tus thawj coj ntawm cov duab zoo, kev tsim tawm xim thiab tus nqi. Tab sis thaum yuav cov qauv pheej yig nrog ib nti, daim duab zoo yog qhov phem dua. Cov khoom cuav tuaj yeem tshwm sim: ntawm ntug ntawm "tus zaj sawv".
  2. LCD - siv cov kua siv lead ua kua matrices nrog lub lens kaw lus. Rov tsim cov duab zoo. Tus nqi sib tw qhov zoo, tab sis poob qis ntawm DLP.
