Qhov sib txawv ntawm LCD thiab OLED TVs
Kev siv tshuab TV tau hloov pauv ntau heev nyob rau xyoo tas los no. Txij li cov ntxaij vab tshaus loj zoo li lub raj mus rau cov TV ntse zoo nkauj uas muaj cov duab meej, thev naus laus zis TV tau hloov pauv ntau heev. Hauv qhov xwm txheej no, ob lub thev naus laus zis tso saib uas feem ntau piv rau yog LCD (Liquid Crystal Display) thiab OLED (Organic Light Emitting Diode). Txawm hais tias zoo li zoo sib xws thaum xub thawj, ob hom kev tso saib no muaj qhov sib txawv tseem ceeb uas cuam tshuam rau qhov zoo ntawm daim duab, kev siv hluav taws xob, kev tsim khoom siv, thiab tus nqi. Cia peb tshawb nrhiav qhov sib txawv tseem ceeb ntawm LCD thiab OLED TV kom ntxaws.
1. Cov Ntsiab Cai Ua Haujlwm thiab Cov Txuj Ci Tseem Ceeb
LCD:
Cov TV LCD siv cov vaj huam sib luag uas muaj ib txheej ntawm cov kua siv lead ua kua uas nyob nruab nrab ntawm ob yam khoom siv polarizing. Cov kua siv lead ua kua no tsis tso tawm lub teeb lawv tus kheej; es tsis txhob, lawv hloov kho lub teeb uas tso tawm los ntawm lub backlight, feem ntau yog lub teeb-emitting diode (LED). Cov vaj huam sib luag LCD muaj peb lub subpixels, txhua xim liab, ntsuab, thiab xiav (RGB), uas ua ke tsim cov xim duab.
OLED:
OLED, ntawm qhov tod tes, yog ib qho thev naus laus zis tso saib uas txhua tus pixel tso tawm nws lub teeb. OLED pixels yog ua los ntawm cov txheej ntawm cov khoom siv organic uas ci thaum siv hluav taws xob. Qhov no txhais tau tias txhua pixel ua haujlwm ua nws lub teeb ci, tso cai rau kev tswj hwm xim thiab qhov ci ntsa iab kom meej dua.
2. Qhov Zoo ntawm Duab
Kev Sib Piv thiab Qhov Tsaus Ntuj:
Cov OLEDs ua tau zoo heev hauv kev sib piv thiab lub peev xwm los tso saib cov xim dub tob. Vim tias txhua lub pixel OLED tuaj yeem tua tag nrho, lawv muaj peev xwm tsim cov xim dub tiag tiag. Qhov no sib txawv ntawm LCDs, uas ib txwm muaj qee lub teeb tawm ntawm lub backlight, ua rau cov xim dub ntawm cov ntxaij vab tshaus LCD tshwm sim xim grey tsaus.
Qhov kaj:
Cov LCDs muaj qhov zoo dua hauv qhov kaj siab tshaj plaws. Vim tias lawv siv lub teeb ci ntsa iab, LCD TVs tuaj yeem ua tiav qhov kaj siab dua li OLEDs. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv qhov chaw kaj heev lossis chav uas muaj ntau lub teeb ci ntsa iab.
Xim Tseeb:
Feem ntau OLEDs muab cov xim zoo dua thiab nplua nuj dua. Qhov no yog vim tias kev tswj hwm txhua pixel ua rau muaj xim ntau dua thiab zoo li tiag tiag. LCD TV kuj tseem tuaj yeem muab cov xim zoo, tab sis lawv feem ntau xav tau cov thev naus laus zis ntxiv, xws li Quantum Dots, kom ua tiav qhov zoo sib xws.
3. Lub Tswv Yim
LCD:
Ib qho teeb meem loj ntawm LCDs yog qhov tsis zoo ntawm cov duab thaum saib los ntawm cov ces kaum sab. Vim yog cov qauv vaj huam sib luag thiab lub teeb polarization, cov xim tuaj yeem zoo li ploj lossis cuam tshuam thaum saib los ntawm cov ces kaum siab.
OLED:
OLED muaj lub kaum sab xis saib dav dua. Vim tias txhua lub pixel tso nws lub teeb, qhov zoo ntawm daim duab, suav nrog qhov ci thiab xim, tseem zoo ib yam txawm tias saib los ntawm cov kaum ntse ntse heev. Qhov no ua rau OLED zoo dua rau kev zaum uas tsis tig ncaj qha rau ntawm lub vijtsam.
4. Lub Sijhawm Teb thiab Tus Nqi Tshiab
LCD:
Feem ntau cov vaj huam sib luag LCD muaj lub sijhawm teb qeeb dua li OLEDs. Txawm hais tias cov vaj huam sib luag LCD uas muaj cov nqi refresh siab thiab latency qis tam sim no muaj thiab muab kev ua tau zoo heev rau kev ua si thiab saib cov ntsiab lus nrawm, OLED tseem muaj qhov zoo.
OLED:
OLED muaj lub sijhawm teb sai heev thiab lub sijhawm ua kom tshiab siab. Qhov no txhais tau tias cov duab txav tau ntse, tsis muaj qhov tsis meej, ua rau nws zoo tagnrho rau kev tso saib cov ntsiab lus ua haujlwm sai lossis rau cov neeg ua si uas xav tau qhov qeeb qeeb heev.
5. Kev Siv Hluav Taws Xob thiab Kev Siv Tau Ntev
LCD:
Cov TV LCD feem ntau siv hluav taws xob tsawg dua hauv ntau qhov xwm txheej, tshwj xeeb tshaj yog thaum tso saib cov duab ci. Vim tias LCDs siv lub teeb backlight uas ci tag nrho lub vijtsam, tsis hais cov ntsiab lus uas raug tso tawm, lawv feem ntau xav tau hluav taws xob tsawg dua los tsim cov duab ci dua li OLEDs.
OLED:
OLEDs siv hluav taws xob tau zoo dua thaum tso saib cov duab tsaus ntuj, vim tias cov pixels dub lossis tsaus ntuj raug kaw tag. Txawm li cas los xij, thaum tso saib cov duab ci, kev siv hluav taws xob OLED tuaj yeem siab dua. Lub neej ntev ntawm OLED kuj raug cuam tshuam los ntawm kev hlawv, qhov twg cov duab tsis txav uas tso tawm ntev dhau tuaj yeem tawm cov duab tom qab tas mus li.
6. Tuab thiab Tsim
LCD:
Feem ntau cov LCDs muaj ntau yam khoom, suav nrog cov khaubncaws sab nraud povtseg polarizing thiab backlights. Qhov no ua rau cov qauv tsim LCD TV feem ntau tuab dua.
OLED:
Ib qho zoo ntawm OLED yog nws qhov nyias. Vim tias nws tsis xav tau lub teeb backlight thiab txhua pixel yog ib qho chaw teeb pom kev zoo, OLED TVs tuaj yeem nyias heev, feem ntau tsuas yog ob peb millimeters xwb. Lawv cov qauv tsim nyias ua rau lawv zoo nkauj tshwj xeeb rau cov zaub uas dai rau ntawm phab ntsa lossis cov qauv tsim sab hauv niaj hnub.
7. Nqe
Feem ntau, cov TV OLED feem ntau kim dua li cov TV LCD. Tus nqi siab dua ntawm OLEDs yog vim muaj thev naus laus zis siab dua thiab cov nqi tsim khoom siab dua. Txawm li cas los xij, cov nqi OLED tau poob qis hauv xyoo tas los no, thaum LCDs tseem pheej yig dua, tshwj xeeb tshaj yog rau cov qauv loj dua.
8. Daim Ntawv Thov thiab Kev Siv
LCD:
Cov TV LCD siv dav hauv ntau yam kev siv, los ntawm cov TV hauv tsev mus rau cov saib computer, ua tsaug rau lawv lub peev xwm los ua kom pom kev kaj siab thiab tus nqi pheej yig dua.
OLED:
OLED feem ntau yog cov neeg nrhiav cov duab zoo tshaj plaws. Nws siv rau hauv cov TV zoo, smartphones, thiab lwm yam khoom siv hluav taws xob uas qhov zoo ntawm daim duab yog qhov tseem ceeb tshaj plaws.
9. Kev Cuam Tshuam Ib puag ncig
Kev tsim cov zaub LCD thiab OLED muaj kev cuam tshuam rau ib puag ncig sib txawv. Cov ntaub ntawv siv, cov txheej txheem tsim khoom, thiab cov kev xav tau zog txhua yam cuam tshuam rau cov pa roj carbon ntawm cov thev naus laus zis no. Feem ntau, vim yog qhov nyuaj thiab cov ntaub ntawv organic siv hauv OLEDs, lawv cov txheej txheem tsim khoom tuaj yeem ua rau ib puag ncig zoo dua, tab sis qhov no tseem nyob ntawm ntau yam thiab kev coj ua ntawm cov tuam txhab tsim khoom.
Xaus
Ob qho tib si LCD thiab OLED muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Kev xaiv ntawm ob qho no nyob ntawm tus kheej cov kev xav tau thiab kev nyiam. Yog tias qhov sib piv siab, cov xim tseeb, thiab lub kaum sab xis dav yog qhov tseem ceeb tshaj plaws, ces OLED yuav yog qhov kev xaiv zoo dua. Txawm li cas los xij, yog tias qhov kaj siab thiab tus nqi pheej yig tseem ceeb dua, ces LCD yuav yog qhov haum zoo dua. Kev siv tshuab niaj hnub hloov pauv tas li, thiab yav tom ntej, peb yuav pom cov kab ntawm ob qho no tsis meej nrog kev nce qib tshiab.
