LCD + Quantum Dots
Uas zoo LCD thiab OLED? Kev txhim kho ntawm cov kev ua tau zoo thiab qhov tsis zoo
Quantum dots yog ib cov txheej txheem uas tuaj yeem txhim kho xim thiab xim xim ntawm cov lus qhia hauv LCD. Semiconductor nanocrystals yuav nqus tau cov spectra tshwj xeeb, feem ntau yog nyob ntawm lawv qhov loj. Cov cuab yeej no muaj peev xwm siv / tsim xim zoo li xim liab, ntsuab, thiab xiav, uas yuav muab cov neeg xim ntau dua.
Quantum dot technology twb nyuam qhuav tau kub siab tom qab los ntawm kev ua lag luam, thiab txawm muaj lub zog thiab OLED no cov tshuab Pimen. Txawm li cas los xij, quantum dot technology tam sim no muaj nyob rau hauv high-end LCD TVs, tab sis nws ntseeg tias nws yuav maj mam nrov nrov dhau lub sijhawm.

Uas zoo LCD thiab OLED? Kev txhim kho ntawm cov kev ua tau zoo thiab qhov tsis zoo
OLED daim ntawv lub npe hu ua Organic Light Emitting Diodes, txhua pixel nws tus kheej yuav tawm tau lub teeb uas tsis muaj qhov sib txawv ntawm qhov nrig lossis xim lim. Thiab txhua lub OLED pixel tuaj yeem muab peb xim ntawm xim liab, ntsuab thiab xiav, thiab tam sim no muaj cov tuam txhab ntxiv xim, tab sis txoj ntsiab cai yog tib yam.
Vim yog qhov tshwj xeeb ntawm OLEDs, nws tsis yog qhov tsim nyog yuav tsum tau npog lub teeb pom kev zoo li lub LCD thaum tso dub, thiab tsuas yog cov pixels yuav tsum tau muab tua kom tsis txhob tawm lub teeb. Thiab yog vim li cas OLED lus qhia coj qhov tseeb "dub". OLED lub xim dub yog tob heev, thiab nws qhov sib txawv yog qhov siab heev. Tib lub sij hawm, nws muaj peev xwm txawm tsim amazing teebmeem thaum piv nrog ntsiab xws li dawb.
OLED technology thawj zaug hauv txoj kev sim hauv xyoo 1987, thiab tau tam sim no dhau los ua ib lub tshuab zoo heev hauv thaj tsam ntse ntse. Vim tias cov ntxaij hlau OLED yog ib txheej tsawg dua li cov ntxaij lim dej LCD, ib lub sij hawm tuab tuab tuab yog thinner, thiab qhov no tseem ceeb rau cov khoom siv txawb. Rau cov khoom siv TV, seb puas yuav xaiv cov khoom ntawm OLED nyob ntawm tus neeg nyiam. Txawm li cas los xij, peb ntseeg hais tias lub slimness ntawm OLEDs tsis yog ib qho zoo dua decisive rau LCD TVs.
Ib-rau-ib sib piv
Vim qhov sib txawv hauv cov qauv yooj yim, peb tuaj yeem saib qhov sib piv ntawm ob qho kev sib txawv ntawm kev siv cov cuab yeej technology, muab cov neeg siv kev paub ntau dua.
Contrast: OLED yeej
Qhov zoo tshaj plaws yog qhov sib txawv ntawm cov brightest white thiab blackest black, thaum lub LCD muaj qhov zoo dua hauv qhov ci ntsa iab (tshwj xeeb tshaj nyob hauv HDR hom), thaum OLED muaj qhov tsaus ntuj dub. Feem ntau, cov lus qhia OLED feem ntau muaj qhov sib txawv dua vim qhov zoo ntawm qhov qib dub yuav ua kom nrov tau qhov txawv.
Lub tswv yim: OLED yeej
Tej zaum qhov zoo tshaj plaws IPS ntxig yuav piv rau cov ntxaij hlau OLED, tiam sis feem ntau cov npo LCD tsis zoo li IPS (tshwj xeeb tshaj yog TV thiab ntse xov tooj), yog li txuas ntxiv rau IPS screens, Sib piv nrog OLEDs, LCD panels muaj qhov me me zoo saib qhov ua tau zoo . Nyob rau hauv pem hauv ntej ntawm OLED TVs, seb cov neeg tuaj saib zaum ntawm lub kaum sab xis, lawv tuaj yeem pom cov ntsiab lus ntawm qhov screen nrog kev ua haujlwm zoo.
Xim gamut: OLED yeej
Los ntawm nam ntawm daim ntawv tsis, qhov zoo ntawm OLED hauv cov xim gamut tsis cuab kev, vim cov chaw dav hlau LCD tam sim no qhia cov quantum dot. Yeej qhov zoo tshaj plaws LG OLED TVs thiab Samsung's saum quantum dot LCD TVs yog piv hauv cov xim gamut.
Tab sis feem ntau tsuas yog qhov zoo tshaj plaws LCD TVs yog piv rau OLED TVs, tag nrho cov xim gamut zoo dua li OLEDs.
Brightness theem: LCD yeej
Txij li thaum LCD TVs feem ntau siv cov nrig qaum rov qab, lawv feem ntau muab kev kaj dua. Hauv kev muaj tiag, qhov zoo tshaj plaws LCDs thiab OLEDs muaj qhov sib txawv ntawm txog 400 NIT hauv qhov kev ci ntsa iab. Zuag qhia tag nrho, LCDs yog qhov zoo tshaj plaws nyob rau theem qis. Koj paub, ntau dua qhov ci ntsa iab yuav ua rau lub vijtsam muaj teebmeem nrig ntawm sab nraud lossis hauv chav nruab hnub.
HDR
HDR hom tuaj yeem ua rau kom ci ntsa iab los ntawm 1000 mus rau 10000 NIT, thiab HDR-enabled OLED TV tuaj yeem cuam tshuam qhov ci ntawm LCD TV lub sijhawm no. Txawm li cas los xij, ib co Sony LCD TVs yuav ua rau kom ci ntsa iab rau 1000 tauj mus rau 1300 NIT, txhua qhov, qhov ci ci ntawm LCD TVs yog siab dua.
