Qhov sib txawv tseem ceeb ntawm OLED thiab TFT-LCD cov ntxaij vab tshaus nyob hauv lawv lub teeb- tawm cov qauv, cov qauv, cov yam ntxwv ua haujlwm, thiab cov xwm txheej ntawm daim ntawv thov, raws li cov lus qhia hauv qab no:
1. Qhov txawv ntawm Lub Teeb-Emitting Principles and Structures
OLED npo:
Tus kheej-emissive: Emits lub teeb ncaj qha thaum tam sim no dhau los ntawm cov khoom siv organic txheej thiab iav substrate, tshem tawm qhov xav tau rau lub teeb rov qab.
Nyias thiab lub teeb yuag: Tshem tawm qhov xav tau ntawm lub teeb pom kev zoo tso cai rau cov qauv tsim thinner (tsawg dua 1 hli tuab) thiab txhawb cov substrates hloov tau (xws li, cov ntxaij vab tshaus foldable).
Cov yam ntxwv ntawm cov khoom siv: Siv cov teeb pom kev organic- cov ntaub ntawv emitting, tso siab rau tam sim no los tsav lub teeb emission.
TFT-LCD npo:
Passive Light Emission: Relies ntawm lub teeb rov qab (xws li, LED raj) rau qhov ci; cov kua siv lead ua kua txheej tswj lub teeb xa tawm kom pom cov duab ntawm qhov hluav taws xob.
Complex Structure: suav nrog lub teeb pom kev zoo, cov kua siv lead ua kua, xim lim, polarizers, thiab lwm yam, feem ntau yog tuab dua OLED.
Cov yam ntxwv ntawm cov khoom: Lub hauv paus ntawm cov kua siv lead ua kua molecules, lawv txoj kev npaj yog tswj los ntawm hluav taws xob teb.
2. Kev sib piv kev ua haujlwm
Brightness thiab Contrast Ratio:
OLED: Cov pixels dub tsis tawm lub teeb txhua, ua rau muaj qhov sib txawv siab heev (theoretically infinite: 1), pom cov duab tsaus nti ntau dua. TFT-LCD: Cia siab rau qhov teeb pom kev zoo; cov qib dub nyob ntawm cov kua siv lead ua lub teeb- thaiv kev muaj peev xwm, ua rau qhov sib piv qis dua (feem ntau 1000: 1 txog 3000: 1).
Saib lub kaum ntse ntse:
OLED: Nws tus kheej -emissive xwm tso cai rau saib cov ces kaum ze li 180 degree, nrog tsawg xim thiab brightness degradation thaum saib los ntawm sab.
TFT-LCD: Cov ntxaij vab tshaus TN ib txwm muaj qhov pom tsis zoo (kwv yees li 90 degree), thaum siab -kawg IPS cov ntxaij vab tshaus tuaj yeem ncav cuag 178 degree, tab sis xim hloov tseem muaj.
Lub sij hawm teb:
OLED: Lub sijhawm teb tsawg dua 0.1 milliseconds, tshem tawm cov dab dab thiab ua kom haum rau nrawm nrawm - txav scenes (xws li kev ua si thiab yeeb yaj kiab).
TFT-LCD: Cov ntxaij vab tshaus ib txwm muaj lub sijhawm teb ntawm kwv yees li 5-16 milliseconds, thaum high-end IPS cov ntxaij vab tshaus tuaj yeem txo qhov no mus rau 2-5 milliseconds, tab sis tseem tsis muaj zog dua OLED.
Kev siv fais fab:
OLED: Pixels tawm thaum pom cov xim dub, uas ua rau muaj kev siv hluav taws xob tsawg (tshwj xeeb tshaj yog rau kev sib tshuam tsaus); kev siv hluav taws xob ntau dua thaum tso saib dawb.
TFT-LCD: Backlight yog ib txwm nyob, ua rau lub zog siv tau ruaj khov; nws tsis muaj zog-txuag kom zoo dua thaum tso saib cov ntsiab lus tsaus.
Lifespan:
OLED: Organic cov ntaub ntawv yog qhov yooj yim rau kev laus, nrog rau lub neej ntev ntawm kwv yees li 5000 puv -screen zaub voj voog (xiav pixels lwj sai dua).
TFT-LCD: Backlight tube lifespan yog kwv yees li 20,000 teev, cov kua siv lead ua kua txheej qhia yuav luag tsis lwj, ua rau muaj kev ruaj ntseg ntau dua nyob rau lub sijhawm ntev - siv.
3. Cov ntsiab lus ntawm qhov zoo thiab qhov tsis zoo
OLED Qhov Zoo: Tus kheej -emissive, siab sib piv, ultra-nyias thiab yoog raws, siv hluav taws xob tsawg (qhov tsaus nti), teb ceev ceev.
Qhov tsis zoo: Lub neej luv luv, tsis tshua muaj txiaj ntsig rau qhov loj me, muaj peev xwm hlawv - thaum tso tawm cov ntsiab lus zoo li qub rau lub sijhawm ntev.
TFT-LCD Qhov Zoo: Lub neej ntev, tus nqi qis, kev siv thev naus laus zis rau qhov loj me, tsis muaj kev pheej hmoo ntawm kev hlawv-in.
Disadvantages: Reliant on backlight, low contrast, thicker and heavyer, siab zog noj nyob rau hauv maub scenes.
4. Cov xwm txheej ntawm daim ntawv thov
OLED Cov ntxaij vab tshaus: Siab-kawg xov tooj ntawm tes (piv txwv li, foldable npo sab nrauv), smartwatches, VR cov khoom siv (yuav tsum tau teb ceev ceev thiab qis latency).
TV (siab- qauv kawg, hais txog cov duab zoo thiab tsim qauv).
TFT-LCD Screens: Lub khoos phis tawj saib, nruab nrab-rau- qis-kawg xov tooj ntawm tes, ntsiav tshuaj, cov khoom siv tsheb (yuav tsum tau siv sijhawm ntev thiab tus nqi qis).
Cov khoom siv sab nraum zoov (tiv taus rau lub teeb ambient cuam tshuam, tab sis yuav tsum muaj siab -brightness backlight).
5. Technology Extensions
OLED Variations:
AMOLED (Active Matrix OLED): Ua ke TFT tsav tsheb los txhim kho pixel tswj qhov tseeb, dav siv hauv xov tooj ntawm tes.
QLED (Quantum Dot OLED): Txhim kho xim los ntawm quantum dots, tab sis tseem tsis tau muaj kev lag luam rau ntawm qhov loj.
TFT{0}}LCD Evolution:
IPS (Integrated Vaj Huam Sib Luag Hloov): Txhim kho qhov pom cov ces kaum thiab xim raug.
Mini-LED Backlight: Txhim kho qhov sib piv los ntawm kev dimming hauv zos, mus txog OLED kev ua tau zoo.
Cov ntsiab lus: OLED ua tau zoo hauv cov duab zoo thiab cov qauv tsim kho tshiab, tsim nyog rau siab -kawg cov khoom siv hluav taws xob; TFT-LCD dominates nruab nrab-rau-qis-kawg kev lag luam nrog nws ruaj khov thiab tus nqi zoo. Ob lub thev naus laus zis ntxiv rau ib leeg, sib koom ua ke tsav kev txhim kho ntawm kev lag luam zaub.
