QLED Thiab OLED: Leej twg yog tus tiag Khiav?

Mar 07, 2017

Tham txog cov npe ua rau kuv xav seb ib tug laus hais tias nyob rau hauv Tuam Tshoj, thaum ob tug tsov sib ntaus sib tua, ib tug yog txhua yam tau txais kev mob. Txawm li cas los, yog dab tsi peb yuav tham txog hnub no, thov nyeem cov lus nram tsab xov xwm ntev.

Muaj yog cia li ib tsab ntawv sib txawv ntawm QLED thiab OLED, tab sis muaj cuab txawv nyob rau hauv lub tshuab thiab marketing. Nyob rau hauv 2017, Samsung tau tso ib tug tshiab QLED TV, ua li cas yog ob tug kev kab ntawm cov keeb kwm keeb kwm thiab kev sib txawv? Yuav ua li cas hom ntawm kev ua lag luam kev luj xyuas thiab yav tom ntej zeem muag?

Nrog kev xav txog cov keeb kwm ntawm txoj kev loj hlob ntawm Samsung thiab LG nyob rau hauv lub teb ntawm TV, yeej nrog qhov kev hloov ntawm TV technology thiab cov kev loj hlob ntawm. CRTPDPLCDOLED txhua theem ntawm ob tuam txhab uas muag tau muaj los yog muaj. Nws yog ib nqi hais tias, Samsung thiab LG tau launched nyob rau hauv 2012 55 nti OLED TV, thiab sim commercialization nyob rau hauv 2013, tab sis tsis yog rau ib lub xyoo, OLED tus biggest ntawm UFW Samsung hloov lub tswv yim.

Yeej, yog ib lub yog vim li cas, nrog rau Samsung thiab LG nyob rau hauv lub ntsej muag ntawm cov tub ntxhais ntawm lub OLED tub ntxhais waterproof technology patent tsis sib haum, tab sis ntau dua los yog Samsung nyob rau hauv kev ua lag luam vim lub saj zawg zog xwm ntawm lub tswv yim.

2014 Samsung teem rau lub 4K LCD TV, tso tawm nyob rau hauv 2015 SUHD TV, nyob rau hauv 2017 los ua ib tug tshiab QLED TV. Nyob rau hauv thiaj li yuav nyob rau hauv lub quantum dot technology, Samsung lag luam 300 quantum dot technology patents nrog lub German Nanosys lub tuam txhab, kuj kis tau rau hauv lub tebchaws United States quantum dot enterprise QD pom kev. Nyob rau tib lub sij hawm Samsung tsis tag muab OLED technology, me me luaj li cas ntawm lub teb ntawm AMOLED muaj ib tug loj hlob sai.

Nyob rau hauv zoo LG vim 2012 tau adhering rau lub OLED camp, thiab lossi txhim kho lub tshuab thiab technology. Nyob rau hauv cov kev taw qhia ntawm OLED khoom LG zoo tshuaj zoo nrog Mitsubishi tshuaj, tshuaj Sumitomo, American UDC, German Covin lub tuam txhab, mus koom tes ua ke txhawb qhov kev kawm ntawm cov kev lag luam OLED cov ntaub ntawv.

Yog li ntawd tam sim no peb pom cov contest ntawm QLED thiab OLED, nyob rau hauv qhov tseeb, yog tsis yog ib tug contest ntawm Samsung thiab LG, tab sis tom qab ob tug technology kev tshawb fawb, cov khoom, marketing contest ntawm cov pab pawg.

QLED yog txawv los ntawm OLED

Nyob rau hauv thiaj li yuav yeej to taub qhov txawv ntawm "Q" thiab "O", nws yog tsim nyog rau kev tsom xam lawv ua ntej.

Qhov zoo tshaj plaws version ntawm lub QLED technology yuav tsum active teeb-emitting quantum dot cov ntaub ntawv, daim ntawv thov ntawm cov zaub ntaus ntawv tsis tau backlight thiab xim cov ntxaij lim dej. Thaum lub tam sim no theem, "bate" yog nyob rau hauv cov kob xiav LED ua ntej lub tsev ntawm quantum dot zaj duab xis, tus tsim ntawm ntau dua purity backlight, los ntawm cov kua siv lead ua molecules coj ntau ntshiab xim ua tau zoo.

Qhov zoo tshaj plaws version ntawm lub OLED OLED technology yuav tsum yog tus organic khoom siv ntawm active luminescence, RGB thawj xim, xim muaj pes tsawg leeg. Tab sis nyob rau ntawm no theem ntawm lub "bate" version yog cov siv ntawm W OLED technology, OLED tsuas ua raws li ib tug self teeb emitting, tab sis muab piv rau tus neeg kho tshuab kev sib hloov ntawm cov kua siv lead ua, tseem muaj lub meej dub thiab siab zoo xws yam ntxwv.

Yog li ntawd nws nkawd hais tias lub ob technology zoo tagnrho version yog nws tus kheej luminous zog, QLED yog ib qho inorganic khoom nws tus kheej luminous, OLED yog ib tug organic khoom nws tus kheej luminous, yog heev rau pem hauv ntej-tom nrhiav zaub technology. Tab sis yog vim li cas yog kev ua lag luam bate version ntawm nws?

Nyob rau hauv qhov tseeb, OLED ua qhov zoo tagnrho version ntawm lub tshuab muaj, nyob rau hauv 2014 CES launched SONY OLED TV yog qhov zoo tagnrho version, muaj ib tug ntau ntawm tshaj tawm hauv xov theem zaub pab kiag li lawm, xws li tus Samsung AMOLED yog zoo tagnrho ". Tab sis lub lag luam yog ib tug high efficiency thiab nqi, WOLED piv rau lub RGB OLED muaj ib tug zoo nqi kom zoo dua thiab cov kev pab lub neej, ntau haum rau cov qib kev ua lag luam.

Qhov zoo tshaj plaws version ntawm ib tug me ntsis kev loj hlob maj mam, tab sis tom qab tag nrho, yog tus "OLED tiam", qhov kev kawm ntawm ib qhov chaw loj, kev ua lag luam yuav muab ntxiv ua siab ntev.

Ces tham txog lub sij nyhuv (piv nrog rau cov bate version).

Brightness: Q xwb. QLED siv LED backlight, los ntawm kev siv ntawm siab brightness LED module, txhim kho lub backlight qauv, koj yuav tau ntxiv txhim khu lub brightness. Zoo li SONY tus dynamic backlight tswv version ntawm lub ncov brightness yuav ncav cuag 4000nit, Samsung tus QLED yuav ncav cuag 2000nit, thiab muaj peev xwm paub meej tias 15s tsis lwj. Tus yam ntxwv ntawm OLED organic teeb-emitting, siab brightness yog ua txhua yam los ua ib tug organic teeb emitting lub cev attenuation, uas ua rau lub cev puas tsuaj tsis tau rov qab los.

Dub theem: O yeej. Muaj tsis muaj tsis ntseeg hais tias OLED yuav kiag li tig tawm lub backlight. QLED kuj muaj ib lub zos lub teeb tswj technology, tab sis yuav ua tsis tau ib tug zoo tswj ntawm txhua pixel (tsuas yog SONY Z9D).

Kho kom tshiab tus nqi & teb lub sij hawm: O yeej. QLED kua siv lead ua molecules nyob rau hauv qhov hluav taws xob lub teeb liab tom qab tau txais ib tug txhua yam kev sib hloov, thiab OLED zoo li ib tug teeb, tus tes hloov qhov yog ua kom tiav nyob rau hauv ib qho instant kev txiav txim.

HDR: Q xwb. QLED muaj ib tug ntau dua brightness, li ntawd, nyob rau hauv tib xim tob thiab grey cov ntaub ntawv, QLED yuav muaj ib tug zoo dua dynamic ntau yam kev kawm.

Xim gamut: Q xwb. Peb yog tag nrho cov bate version, yog backlit + xim lim zaj duab xis hom, tab sis lub quantum dot spectrum muaj ib yam kom zoo dua.

Visual lub: O yeej. OLED txawm txoj kev 180 degrees.

Uniformity: O yeej. OLED ib leeg ntawm lwm yam uas cov yam ntxwv ntawm txhua pixel luminescence, txaus los tuav lub zos tswj ntawm lub QLED teeb tuaj ntawm lub uniformity ntawm lub screen.

Grey: Q xwb. Duab ntxoov ntxoo kev nthuav dav thiab xim kev hloov teeb meem seb nws yog WOLED los yog RGB OLED yuav tsum muaj ib yuav tsis txhob muaj teeb meem. Vim hais tias OLED siv PWM los yog DC dimming hom. Thaum cov xim ntawm lub vaj huam sib luag mus cuag 10bit, uas yog, thaum lub 1024 theem, nws yog tsim nyog los xav txog tej yam lub kua siv lead ua molecules uas tswj lub zoo kauj, yog ib tug heev nyuaj tshaj plaws.

Fais fab kev noj: Q xwb. OLED hwj chim saving, yog nyob rau hauv qhov kev kawm ntawm cov dub scene, tab sis lub cev siv, tib loj ntawm lub OLED yuav loj tshaj li tus QLED lub hwj chim.

Cov kev sib piv ntawm thiaj li muaj ntau yam, QLED thiab OLED bate version ntawm tib yuav tau hais. Tsis muaj lub zem lub ob camps yog tam sim no zoo-matched nyob rau hauv lub dag lub zog lub xeev.

Leej twg yog tus khiav?

Vim li cas peb yuav tsum paub qhov txawv lub sij hawm? Peb muaj kev txhawj xeeb txog lub saj zawg zog screen technology, QLED thiab OLED printing tshuab, yuav ua rau ultrathin saj zawg zog screen. Yuav tsis coexist? Tsis tsuas yog lub bate version ntawm thaj yeeb coexistence, lub neej yav tom ntej yuav tau upgraded rau ib qho zoo tagnrho version, tib yuav muaj kev thaj yeeb coexistence.

Nyob rau hauv cov zaub technology, peb muaj ntau txoj kev mus cuag, tab sis tsis muaj ib tug yog omnipotent, muaj yog ib txwm ib tug tej yam complementary kev sib raug zoo. Cia li zoo li nyob rau hauv lub lag luam hauv internet thiab offline, zaj duab xis thiab TV nyob rau hauv lub 3D thiab VR, Suav tshuaj thiab Western cov tshuaj, yog cov coexistence ntawm lub kev sib raug zoo.

Txawm li cas los, nws yog tej yam yuav tau paub qhov txawv lub sij hawm, vim hais tias cov ntshav yog qhuav tuag. Yuav ua li cas yog vim li cas rau qhov no? Tus nqi kom zoo dua ntawm technology los mus txhim kho cov efficiency ntawm txiav txim siab, uas yog tus ceev tshaj ceev, thiab txo tus nqi, uas muaj peev xwm muaj lub xeem luag.
