Koj puas paub qhov txawv ntawm LCD, LED thiab OLED yog dab tsi?

Lub vijtsam zaub yog hu ua ib qho kev tsim khoom loj tshaj plaws ntawm lub xyoo pua 20th.

Nws tsis yog ntau dhau.Peb lub neej yeej muaj koob meej vim nws lub ntsej muag.

Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, cov ntxaij vab tshaus tsis txwv rau kev siv cov ntxaij vab tshaus TV.

Kev lag luam loj lojLED qhia cov ntxaij vab tshauspib tawg rau hauv peb lub neej, xws li khw malls, xinesmas, nws tuaj yeem pom nyob rau ntau qhov chaw xws li cov chaw ua si sab hauv tsev, thiab lub sijhawm no, LCD, LED, OLED thiab lwm yam kev tshaj lij kuj tseem nyob hauv peb pob ntseg, txawm tias muaj ntau yam. neeg tham txog lawv, tab sis feem ntau cov neeg tsis paub me ntsis txog lawv.

Yog li, qhov txawv ntawm Lcd, coj thiab oled yog dab tsi?

LCD,LED DISPLAYThiab OLED

1, LCD npo

LCD yog luv rau Liquid Crystal Display ua lus Askiv.

Muaj feem ntau TFT, UFB, TFD, STN thiab lwm yam.Nws cov qauv muaj xws li pob yas, iav pob, thav duab kua nplaum, iav substrate, sab sauv polarizer, txheej txheej qhia, kua siv lead ua kua, conductive ITO qauv, conduction point, IPO electrode thiab qis polarizer.

Noj LCD advertising npo ua piv txwv, nws tau txais kev paub zoo tshaj plaws TFT-LCD, uas yog nyias zaj duab xis transistor kua siv lead ua zaub.Nws cov qauv yooj yim yog tso kua siv lead ua lub thawv rau hauv ob lub khob sib luag ntawm cov iav substrates, teeb cov yeeb yaj kiab nyias nyias (xws li TFT) ntawm cov iav substrate qis, teeb xim lim rau sab sauv substrate iav, kev sib hloov ntawm cov kua siv lead ua kua molecules yog tswj los ntawm lub teeb liab. thiab voltage hloov ntawm nyias zaj duab xis transistor, thiaj li ua kom tiav lub hom phiaj tso saib los ntawm kev tswj seb lub teeb polarized ntawm txhua pixel yog emitted los yog tsis.

Lub hauv paus ntsiab lus ntawm cov kua siv lead ua kua yog tias cov kua siv lead ua kua yuav nthuav tawm cov yam ntxwv sib txawv nyob rau hauv qhov kev txiav txim ntawm qhov sib txawv voltages.Cov kua siv lead ua kua zaub screen yog tsim los ntawm ntau cov kua siv lead ua kua.Hauv lub vijtsam monochrome kua siv lead ua kua, cov kua siv lead ua kua yog pixel (qhov me tshaj plaws uas tuaj yeem pom ntawm lub computer screen), hauv cov xim kua siv lead ua kua zaub screen, txhua pixel muaj xim liab, ntsuab thiab xiav kua crystals.Nyob rau tib lub sijhawm, nws tuaj yeem txiav txim siab tias muaj 8-ntsis sau npe tom qab txhua cov kua siv lead ua kua, thiab tus nqi ntawm cov ntawv sau npe txiav txim siab qhov ci ntawm txhua qhov ntawm peb cov kua siv lead ua kua, txawm li cas los xij, tus nqi ntawm cov ntawv sau npe tsis ncaj qha. tsav lub ci ci ntawm peb cov kua siv lead ua kua, tab sis nkag los ntawm "palette.Nws yog qhov tsis muaj tseeb rau nruab txhua pixel nrog lub cev sau npe.Qhov tseeb, tsuas yog ib kab ntawm kev sau npe yog nruab.Cov ntawv sau npe no txuas nrog txhua kab ntawm pixels nyob rau hauv lem thiab loaded rau hauv cov ntsiab lus ntawm kab no, tsav txhua pixel kab los tso saib ib daim duab tiav.

2, LED SCREENS

LED yog luv luv rau Lub Teeb Emitting Diode.Nws yog ib hom semiconductor diode, uas tuaj yeem hloov hluav taws xob rau hauv lub teeb lub zog.

Thaum cov hluav taws xob sib xyaw nrog lub qhov, pom lub teeb tuaj yeem tawg, yog li nws tuaj yeem siv los ua lub teeb emitting diodes.Zoo li cov diodes ntau, lub teeb emitting diodes yog tsim los ntawm pn hlws ris thiab kuj muaj unidirectional conductivity.

Nws lub hauv paus ntsiab lus thaum qhov zoo voltage ntxiv rau lub teeb emitting diode, lub qhov txhaj rau hauv N cheeb tsam ntawm P cheeb tsam thiab cov electrons txhaj rau hauv P cheeb tsam ntawm N cheeb tsam, nyob rau hauv ob peb microns nyob ze ntawm lub PN hlws ris, nws yog compounded. nrog electrons nyob rau hauv N cheeb tsam thiab qhov nyob rau hauv P cheeb tsam raws li feem ntau tsim spontaneous emission fluorescence.

Lub zog lub xeev ntawm electrons thiab qhov nyob rau hauv cov khoom siv semiconductor sib txawv.Thaum cov electrons thiab qhov sib xyaw ua ke, lub zog tso tawm txawv.Lub zog tso tawm ntau dua, lub wavelength luv ntawm lub teeb emitted.Feem ntau siv yog diodes uas tawm teeb liab, lub teeb ntsuab lossis lub teeb daj.

LED yog hu ua Fourth Generation Light Source, uas muaj cov yam ntxwv ntawm kev txuag hluav taws xob, kev tiv thaiv ib puag ncig, kev nyab xeeb, kev ua haujlwm ntev, kev siv hluav taws xob tsawg, tsis tshua muaj hluav taws xob, siab ci, tsis muaj dej, me me, shockproof, yooj yim dimming, concentrated teeb beam, yooj yim txij nkawm , thiab lwm yam, nws tuaj yeem siv dav hauv ntau yam xws li kev taw qhia,LED zaub, kho kom zoo nkauj, backlight, general teeb pom kev zoo, thiab lwm yam.

Piv txwv li, LED zaub screen, Advertising LED Screen, tsheb teeb liab teeb, tsheb teeb, LCD backlight, tsev teeb pom kev zoo thiab lwm yam teeb pom kev zoo.

3, OLED npo

OLED luv luv rau Organic Light-Emitting Diode.Kuj hu ua organic electric laser zaub, organic teeb emitting semiconductor.

Qhov diode no tau pom nyob rau hauv chav kuaj hauv xyoo 1979 los ntawm Suav tus kws tshaj lij Asmeskas Asmeskas Deng Qingyun.

OLED muaj cov khoom siv sab nraud OLED thiab lub teeb emitting cov ntaub ntawv clamped nyob rau hauv nws, nrog rau cathode, emission txheej, conductive txheej, anode thiab puag.Txhua chav OLED zaub tuaj yeem tswj tau los tsim lub teeb ntawm peb xim sib txawv.

OLED zaub thev naus laus zis muaj cov yam ntxwv ntawm tus kheej-luminous, siv cov khoom siv nyias nyias txheej thiab iav substrate.Thaum muaj hluav taws xob ncig, cov khoom siv organic no yuav tawm lub teeb, thiab lub ntsej muag lub ntsej muag ntawm OLED zaub screen loj, thiab tuaj yeem txuag hluav taws xob.Txij li xyoo 2003, cov cuab yeej siv no tau siv rau MP3 suab paj nruag.

Niaj hnub no, tus neeg sawv cev tseem ceeb ntawm OLED daim ntawv thov yog lub xov tooj ntawm tes screen.OLED npo tuaj yeem pom cov duab zoo sib xws, thiab cov duab tso saib yuav pom tseeb thiab tiag.Vim yog cov yam ntxwv ntawm cov kua siv lead ua kua, LCD npo tsis txhawb kev khoov.Hauv qhov sib piv, OLED tuaj yeem ua rau hauv qhov screen nkhaus.

Qhov txawv ntawm Peb

1, Nyob rau xim gamut

OLED npo tuaj yeem tso saib cov xim tsis kawg thiab tsis cuam tshuam los ntawm cov teeb pom kev zoo, tab sis LED Screen nrog qhov ci zoo dua thiab pom lub kaum ntse ntse.

Pixels muaj txiaj ntsig zoo thaum pom cov duab dub tag nrho, tam sim no, xim gamut ntawm LCD npo yog nyob nruab nrab ntawm 72 thiab 92 feem pua, thaum lub vijtsam coj yog siab dua 118 feem pua.

2, Hais txog tus nqi

LED cov ntxaij vab tshaus ntawm tib qhov loj yog ntau tshaj li ob npaug li kim li LCD cov ntxaij vab tshaus hauv me me pixel suab coj cov yeeb yaj kiab phab ntsa, thaum OLED cov ntxaij vab tshaus kim dua.

3, Nyob rau hauv cov nqe lus ntawm mature technology ntawm brightness thiab seamless.

LED npo yog zoo dua li LCD npo thiab OLED nyob rau hauv brightness thiab seamless, tshwj xeeb tshaj yog nyob rau hauv loj loj coj video phab ntsa rau advertising screen los yog sab hauv tsev lag luam digital signage siv.

Whereas LCD lossis OLED rau qhov loj loj digital video phab ntsa uas xav tau spliced, qhov sib txawv ntawm cov vaj huam sib luag yuav cuam tshuam qhov kev ua tau zoo thiab cov neeg saib.

4, Nyob rau hauv cov nqe lus ntawm video kev ua tau zoo thiab lub kaum sab xis ntawm cov zaub

Qhov kev tshwm sim tshwj xeeb yog qhov pom lub kaum ntse ntse ntawm lub vijtsam LCD yog qhov me me, thaum lub vijtsam LED tau txaus siab rau hauv txheej txheej thiab kev ua haujlwm zoo nrog kev tsim kho thev naus laus zis ntawm cov zaub coj, ntxiv rau, qhov tob ntawm lub vijtsam LED zoo txaus tshwj xeeb hauvYONWAYTECH nqaim pixel suab coj zaub daws teeb meem.
