Cov qauv TV LCD tseem nrov heev niaj hnub no. Nws yog qhov tsim nyog, raws li kws tshaj lij, vim muaj cov zoo li hauv qab no: cov duab zoo, qhov loj me me, kev siv yooj yim, tsim nyog thiab tus nqi pheej yig.
Dab tsi yog LED TV?
Yog li, LED TV yog khoom siv tau. Nws yog LCD TV txais khoom. Hauv qhov no, lub matrix yog teeb tsa, ua ntej ntawm txhua yam, muaj lub teeb liab tshwj xeeb los ntawm teeb ntawm LEDs.
Dab tsi yog lo lus luv txhais tau?
Piav qhia cov lus luv luv ntawm LED - "Lub Teeb Emitting Diode". Cov tswvyim no siv rau TV hauv qab no: nws yog LCD TVs nrog LED-backlight, uas yog cov cuab yeej ua haujlwm ntawm cov kua siv lead ua kua. Thiab ntawm no nws yog ib qho tseem ceeb uas lub vijtsam hauv cov khoom siv no tau raug teeb pom kev ncaj qha nrog kev pab ntawm LEDs.
Lub ntsiab cai los ntawm cov LED TV tau teeb
Muaj cov thawj ntawm LCD TV qauv. Lawv siv teeb roj raws li cov khoom siv txias. Nws yuav tsum raug sau tseg tias muaj ib tug xov tooj ntawm qhov tsis zoo ntawm qhov tshwj xeeb hauv kev siv ntawm ib tus LED matrix hauv lub teeb rov qab. Cov neeg tsim khoom tau lees tias qhov kev txhim kho tseem ceeb ntawm cov duab nws tus kheej. Nyob rau lub sijhawm tam sim no, muaj qee tus lej ntawm cov yam ntxwv uas muaj feem cuam tshuam hauv qhov xwm txheej tam sim no li cas cov neeg tuaj saib lub TV pom cov duab no. Ntawm cov no, feem ntau yog cov yam ntxwv hauv qab no:
-Ua kom zoo thiab ci ci, -Qhov tsis sib xws, - qhov tob ntawm cov xim dub ntu
-Cov kev ua tau zoo ntawm cov xim rov qab.
Thaum lub sijhawm tam sim no, LED-backlit TVs yog qhov kev coj ua rau kev sib piv nrog lawv tus kheej cov kwv tij thawj coj.
Ntau tus xav paub dab tsi raws nraim LED TV. Lo lus teb rau lo lus nug no yog cuam tshuam ncaj qha rau qhov muaj txiaj ntsig qhov txawv ntawm cov teeb liab LED. Qhov yog tias thaum sim tswj kom tau qhov degree ntawm diode luminescence, nws tiav kiag li ua tiav qhov kev tswj hwm tseem ceeb ntawm lub teeb pom kev zoo los yog, ntawm qhov tsis sib xws, qhov tsaus ntuj ntawm qee qhov chaw ntawm lub screen. Nyob rau lub sijhawm ua haujlwm nyob hauv lub xeev, lub teeb diode tsis nyob rau hauv txhua txoj kev coj los xyaum ua qhov ci. Vim li no, qee yam kev hloov ntawm LED diodes cov ntaub ntawv kiag li cov cheeb tsam dub. Raws li qhov kev thov ntawm cov txheej txheem thev naus laus zis no, hauv kev coj ua, nws muaj peev xwm ua tiav qhov kev xav ntawm cov xim dub, nrog rau kev ua kom zoo thiab tsis muaj peev xwm ntawm kev sib piv. Kev rov zuag xim tag nrho tseem yuav pom tau thiab txhim kho tseem ceeb, uas ua ke muaj qhov zoo ntawm qhov zoo ntawm cov duab tshwm sim. Ua tsaug rau qhov ci ntawm LED, LED LCD TVs tau muaj qhov ntsuas teeb ci tseem ceeb. Kev siv cov diode matrix ua rau nws muaj peev xwm ua tiav nyob rau theem ntawm kev siv feem ntau ntawm cov yam ntxwv uas muaj lub luag haujlwm xa cov duab ntawm cov duab zoo. Nws yog qhov zoo tshaj plaws hauv kev sib piv nrog rau yav dhau los. Qhov tseem ceeb txo ntawm kev siv hluav taws xob tau suav hais tias yog lwm qhov txiaj ntsig tseem ceeb ntxiv.
Kov raws li cov lus nug ntawm dab tsi LED TV yog, ib qho yuav tsum tsis txhob hnov qab txog cov txiaj ntsig tseem ceeb uas muaj nyob hauv seem tsim ntawm lub tshuab no. Uas yog, nyob rau hauv tus txheej txheem ntawm kev tsim khoom thiab ntau lawm ntawm cov LED LCD TVs, txhua qhov teeb meem aerosol daim ntawv thov thiab cov mercury raug cais tawm ntawm kev siv. Yog li, qhov kev txiav txim siab no muaj txiaj ntsig zoo ntawm kev tiv thaiv ib puag ncig thiab kev nyab xeeb rau tus kheej.
Hauv LED backlighting, ob qho tib xim-xim thiab ob- lossis peb-xim diodes tuaj yeem siv tau. Qhov kev tsim qauv no muab lub sijhawm tshwj xeeb rau kom nce qhov ntau ntau ntawm qhov ntsuas ntawm cov xim. Ua ntej tshaj plaws, nws yog kev coj los siv backlighting nrog dawb LEDs, yog li txo qhov kev hem thawj ntawm kev nyuaj nrog daim duab.
Qhov zoo tshaj plaws LED TVs mus dhau txheej txheem ntau lawm uas siv technology hauv zos dimming. Nws yog lub luag haujlwm, vim li ntawd, rau lub zos dimming. Raws li cov lus hais saum toj no "hauv zos dimming" cov txheej txheem thev naus laus zis, kev tswj ntawm LEDs tau nqa tawm hauv pawg, uas muaj ntau lub ntsiab lus.
Qhov saum toj no thev naus laus zis muaj qhov tsis zoo. Nws dag nyob rau hauv qhov nyuaj ua tau uas tuaj yeem pom nyob rau hauv cov tsos ntawm kev tsis zoo-tsis sib xws. Nws tshwm, raws li txoj cai, hauv cov kis thiab tso tawm cov duab. Hauv kev xyaum, nws tau ua pov thawj tias qhov tsos ntawm lub teeb pom kev zoo nyob rau hauv cov chaw hauv cheeb tsam uas muaj qhov ci ntsa iab ntawm cov teeb rov qab thiab cov pob dub hauv cov chaw uas qhov chaw taws teeb rov qab tau tawm.
Kev Xaiv Kom Zoo Rau LED TVs
Tab sis LCD LED TVs tseem muaj lwm txoj hauv kev, hu ua OLED TVs. Lawv kuj muaj qhov tsis txaus ntseeg tus naj npawb ntawm qab ntxiag zoo, tab sis lawv txawv nyob rau hauv ib qho tseem ceeb drawback rau feem ntau cov neeg yuav khoom - tus nqi siab. Hauv cov catalog ntawm cov khw muag khoom hluav taws xob, cov cuab yeej siv tshuab ntawm ntau cov qauv thiab cov nqi khoom siv feem ntau yog nthuav qhia (ntawm lawv, raws li txoj cai, muaj cov cuab yeej technology zoo los ntawm Loewe, thiab 4K (UHD) TVs nrog LED backlighting).
Koj yuav tsum saib dab tsi cov kev txwv thaum yuav khoom LCD LED TVs?
Thaum xaiv LCD TV TV, koj yuav tsum txiav txim siab koj qhov kawg los ntawm kev sib piv ncaj ncaj raws li cov hauv qab no:
-Tus daws teeb meem HD los sis HD Npaj daws;
-Saib Cov 3D;
-sib txuam nrog HDR thev naus laus zis;
-screen kab pheeb ces kaum;
-Qhov muaj peev xwm txuas rau Is Taws Nem (suav nrog ntawm Wi-nkaus).
Ua ntej yuav khoom, koj yuav tsum coj mus rau hauv tus account qhov tseeb tias tom qab qhov kev tsim kom muaj kev vam meej multimedia system yog LED TV uas muaj ntau qhov chaw nres nkoj HDMI. Lawv yuav tsum rau kev sib txuas ntawm theem pib ntawm cov DVD ua si, teeb lub npov saum toj, kev ua si hauv tuam txhab thiab lwm cov cim teeb meem.
LCD LED TV hauv cov ntawv teev npe ntawm cov khw muag khoom ntawm ntau cov khoom siv hluav taws xob feem ntau sawv cev los ntawm ntau cov cuab yeej, qhov twg txoj cai nqe pom tus cwj pwm los ntawm 2095 txog 79,990 rubles.
Ntawm cov khoom siv hluav taws xob hauv Is Taws Nem nrov npe, koj tuaj yeem paub koj tus kheej kom ntxaws nrog cov cuab yeej tshwj xeeb, cov lus qhia rau kev siv lub cuab yeej, muaj kev yuav khoom, kev lees yuav, kev xa khoom lossis tuaj tos tus kheej hauv koj lub nroog.
Tsim nyog ntawm koj cov qauv ua qauv ntawm LCD LED TVs
LG 24LH451U
Ib qho qauv me me uas muaj qhov daws teeb meem HD-Npaj daws teeb meem (1366 x 768) thiab TV me me chav ua noj. Cov cuab yeej ntaus ntawv tau nruab nrog cov yeeb yam zoo li hauv qab no:
