Nrhiav seb yuav nrhiav dab tsi ntxiv dua li kab pheeb ces kaum thiab kev daws teeb meem.

1. Tshawb xyuas qhov chaw muaj

Qhov loj ntawm TV nyob ntawm qhov chaw muaj nyob hauv qhov chaw teeb tsa. Yog li ntawd, ua ntej ntawm tag nrho cov, nws yog tsim nyog los soj ntsuam seb lub tshiab ntaus ntawv yuav haum rau muaj. Ntsuas qhov ntev ntawm lub txee niche lossis phab ntsa qhov chaw thiab sau nws. Tom qab ntawd, qhov no yuav pab kom nkag siab seb lub TV uas tau xaiv yuav haum rau hauv lossis yog tias koj yuav tsum tau me ntsis kev noj qab haus huv.

2. Sib piv cov kab pheeb ces kaum

Qhov loj ntawm qhov screen, qhov muaj zog ntawm cov nyhuv immersive. Tab sis tsuas yog yuav lub TV loj tshaj plaws nrog tag nrho koj cov nyiaj tsis yog lawm. Tseeb, qhov kev xaiv ntawm kab pheeb ces kaum yog cuam tshuam los ntawm qhov kev ncua deb ntawm lub vijtsam thiab qhov zoo ntawm cov ntsiab lus, thiab cov kev tsis sib xws no zoo sib xws: qhov ze rau cov zaub, qhov tseeb ntau daim duab thiab pom ntau qhov tsis zoo.

Qhov kev ncua deb ntawm qhov zoo tshaj plaws yog suav tias yog qhov kev ncua deb ntawm 1, 2-2, 5 kab pheeb ces kaum: qhov no yog qhov cov neeg tsim khoom pom zoo.

Piv txwv li, rau 40 ntiv tes nws yuav yog li 1.2-2.5 meters, rau 65 ntiv tes nws yuav yog 2-4 meters. Muab hais tias chav tsev dav txaus thiab koj npaj yuav saib cov ntsiab lus zoo digital, koj tuaj yeem tsom mus rau cov qauv no.

Yog tias tsis muaj ntau qhov chaw, thiab lub teeb liab tsis yog ib txwm nyob rau hauv kev daws teeb meem siab, koj yuav tsum nrhiav kev sib haum xeeb, coj mus rau hauv tus account qhov kev cia siab ntawm kab pheeb ces kaum, qhov deb thiab cov ntsiab lus zoo.

• Yog tias koj xav tau kab pheeb ces kaum loj dua- saib xyuas lub teeb liab zoo lossis zaum deb ntawm TV.
• Yog chav me me- txo cov kab pheeb ces kaum los yog ua kom cov teeb liab zoo.
• Yog hais tias cov ntsiab lus yog questionable zoo- txav deb ntawm qhov screen lossis nqa ib kab pheeb suab me me.

3. Txiav txim siab txog kev daws teeb meem

Cov kev daws teeb meem ncaj qha cuam tshuam rau theem ntawm cov duab nthuav dav, tau kawg, muab cov teeb liab zoo. Xyoo 2020, plaub tus qauv muaj nyob hauv khw, tab sis HD yuav luag tsis pom, thiab 8K tseem suav tias yog kab txawv. Qhov tseeb, koj yuav tsum xaiv ntawm Full HD thiab 4K.

Txoj cai "qhov zoo dua" dua tsis ua haujlwm ntawm no, txij li lub TV nrog lub vijtsam loj tuaj yeem qhib tau kiag li yog tias muaj lub teeb liab tsim nyog. Tag nrho cov kev xaiv los mus nkag siab txog cov ntsiab lus uas koj npaj yuav saib ntau zaus.

• HD (1280 × 720) daws teeb meem - tsis ncaj ncees lawm, tab sis tib lub sijhawm nws yog qhov kev xaiv zoo tshaj plaws rau kev saib TV hauv av thiab TVs nrog kab pheeb ces kaum txog li 32 ntiv tes. Nws tsuas yog pom nyob rau hauv feem ntau cov qauv siv nyiaj txiag thiab tsuas yog tsim rau lub caij ntuj sov tsev lossis chav ua noj.
• Full HD (1,920 × 1,080) daws teeb meem - yog maj mam hloov los ntawm kev nce qib 4K, tab sis tam sim no nws tseem nyob hauv kev thov thiab tseem yog qhov nrov tshaj plaws. Feem ntau ntawm cov ntsiab lus muaj nyob rau hauv 1,080p.
• UHD los yog 4K (3 840 × 2 160) yog ib hom kev loj hlob uas yuav dhau los ua qhov tseem ceeb hauv ob peb xyoos tom ntej no. Zoo tagnrho rau YouTube yeeb yaj duab, tsos, TV qhia, ua si. Rau TV raws nws yuav phem dua Full HD.
• 8K (7 680 × 4 320) yog tus qauv qhia tsis ntev los no uas yog ob zaug siab dua hauv 4K daws teeb meem thiab plaub zaug li Full HD. Tsis muaj qhov taw tes hauv kev yuav hauv 3-4 xyoo tom ntej, vim tsuas muaj ob peb tus qauv muaj nyob hauv khw, thiab tag nrho cov ntsiab lus tsuas yog txwv rau kaum ob cov yeeb yaj kiab hauv YouTube.

4. Xaiv cov tshuab matrix

Hauv kev nrhiav qhov tseeb xim luam tawm, siab ci ntsa iab thiab qhov sib txawv, cov neeg tsim khoom niaj hnub sim nrog cov lus qhia. Tam sim no txhua lub TVs muaj peb hom matrices: LED, QLED, OLED. Txhua yam ntawm lawv muaj qhov zoo thiab qhov tsis zoo, yog li koj yuav tsum xaiv raws li koj nyiam.

LED

Ua kua siv lead ua technology. Qhov tseeb, tib lub LCD (LCD), tab sis backlit tsis yog ntawm cov teeb fluorescent, tab sis ntawm LEDs. Qhov no ua rau nws muaj peev xwm txuag tau qhov chaw thiab tsim cov khoom siv nyias nyias, yog li cov tuam ntxhab tau siv hom LED backlighting rau hauv lub npe. Nws tau tuav, txawm tias cov matrices tsis txawv ntawm cov laus.

LED panels yog tam sim no feem ntau. Lawv muaj ob hom, uas txawv nyob rau hauv kev npaj ntawm cov muaju nyob rau hauv lub matrix.

• IPS - nyob rau hauv xws li panels, kua siv lead ua molecules yog ib txwm nyob rau tib lub sijhawm mus rau lub dav hlau ntawm cov zaub thiab tawg lub teeb rau sab. Qhov no muab cov ces kaum pom zoo heev thiab cov xim luam tawm, tab sis qhov sib piv raug kev txom nyem, thiab cov xim dub hauv lub teeb qis yog ntau dua li grey tsaus.
• VA - nyob rau hauv cov matrices no, cov muaju yog nyob rau hauv perpendicular mus rau lub screen, uas tso cai rau koj mus thaiv tag nrho lub teeb thiab muab ib tug sib sib zog nqus dub xim. Txawm li cas los xij, qhov no tib lub sijhawm degrades daim duab thaum hloov lub kaum sab xis saib: kab rov tav, qhov ntxoov ntxoo yog distorted, thiab vertically, nthuav dav ntawm cov duab ntxoov ntxoo.

Ob lub thev naus laus zis yog siv rau hauv cov qauv nkag. LED - IPS tuaj yeem pom zoo rau ntau yam ntsiab lus rau tag nrho tsev neeg hauv lub teeb ntuj thiab rau kev ua si video. LED - VA yog qhov kev xaiv zoo tshaj plaws rau cov neeg nyiam ua yeeb yaj kiab thiab TV qhia ib leeg lossis ua ke thaum yav tsaus ntuj.

QLED

QLED matrices yog, qhov tseeb, ib qho kev txhim kho ntawm cov thev naus laus zis dhau los thiab tsis muaj dab tsi cuam tshuam nrog OLED. Tab sis nrog rau cov ntaub ntawv ntawm tib manufacturers, lawv tau singled tawm nyob rau hauv ib tug nyias muaj nyias ib qeb. Lo lus no yog siv los ntawm Samsung, LG hu lawv Nano Cell, Sony hu lawv Triluminos.

Qhov sib txawv ntawm cov thev naus laus zis no nyob hauv kev siv xiav LEDs rau kev teeb pom kev zoo. Lawv tsim cov xim liab thiab ntsuab uas ploj lawm rau RGB palette vim muaj txheej ntxiv nrog quantum dots. Tag nrho cov no muab cov duab ci dua thiab ntau dua.

QLEDs yog kim dua thiab yuav tsum tau txiav txim siab ntawm ib nrab nyiaj txiag.

Txawm hais tias feem ntau manufacturers twb nruab lawv nyob rau hauv tag nrho cov qauv tsuas yog cov thawj sawv daws yuav.

OLED

Lub hauv paus sib txawv, ntau niaj hnub siv tshuab raws li cov organic teeb-emitting diodes. Lawv tsis xav tau ntxiv illumination, txij li thaum lawv tus kheej emit lub teeb thaum tam sim no thov, muaj peev xwm tua tag nrho. Qhov no tso cai rau OLED TVs khav theeb xim gamut thiab qhov sib txawv, cov dub zoo meej thiab tsuas yog ob peb millimeters hauv tuab.

Qhov tsis zoo ntawm cov matrices xws li ci ntsa iab uas tsis zoo rau lawv cov khoom siv LED thiab tus nqi siab heev.

Tsis tas li ntawd, OLED cov ntxaij vab tshaus muaj qhov cuam tshuam rau "hlawv-hauv" - qhov tshwm sim ntawm cov khoom seem ntawm cov duab zoo li qub xws li kev sib cuam tshuam hauv kev ua si lossis TV channel tuag.

OLED matrices tuaj yeem pom zoo nyob rau hauv rooj plaub uas cov peev nyiaj yuav khoom tsis txwv, thiab cov ntsiab lus tseem ceeb yuav yog cov yeeb yaj kiab thiab TV series. Rau kev ua si, nws yog qhov zoo dua los xaiv QLED.
