Qhov qhia txog LED, OLED thiab LCD

Mar 20, 2017

LCD

LCD yog tag nrho lub npe ntawm lub LCD Ua kua Crystal Display, TFT ntau, UFB, TFD, STN thiab lwm hom LCD.

Tus qauv ntawm lub LCD yog muab tso rau hauv cov dej ua kua siv coj los ua ob daim iav substrate, iav substrate yog muaj nyob rau hauv TFT (nyias zaj duab xis transistor), nyob rau iav substrate yog npaj rau xim lim, kev taw qhia kev taw qhia thiab hloov voltage los ntawm TFT Los tswj cov kua siv lead ua kua molecules, thiaj li ua tau qhov kev tswj ntawm txhua lub pixel lossis tawm ntawm lub teeb kom pom.

LCD yog ib hom khoom ntawm cov khoom thiab kua, nws tsis yog luminous, yuav tsum tau siv lub teeb ci ntxiv. Vim li no, cov roj teeb muaj feem xyuam rau qhov ci ntsa iab ntawm lcd.

Lub qhov muag ntawm lub LCD yog mob qhov teeb meem. Thaum lub tsom teeb dhau ntawm lub ncov qaum ntuj, cov kua siv lead ua kua thiab cov txheej txheej, cov teeb zis yog directional. Uas yog hais tias, feem ntau ntawm lub teeb yog tawm ntawm lub vijtsam vertically, yog li los ntawm ib qhov kev pom loj los saib cov duab LCD, lawv tuaj yeem tsis pom thawj xim, thiab tseem tuaj yeem pom tag nrho cov neeg dawb los yog tag nrho cov dub.

LED

LED yog ib lub teeb emitting diode Teeb Emitting Diode. LED daim ntawv thov yuav muab faib ua ob pawg: ib qho yog qhov LED; Ob tug LED tib daim ntawv thov, nrog rau cov kev taw qhia LED, infrared LED. Tam sim no ntawm LED zaub, nrog: qis zog noj, kev pab cuam lub neej ntev, qis nqi, qaim siab, tsis ua hauj lwm, tsis pom kev loj, pom qhov pom thiab ua li ntawd.

Ntsiab cai ntawm LED luminescence thiab luminescent khoom:

Cov khoom siv ntawm semiconductor muaj ib qho khoom muaj nuj nqis heev, hu ua cov cab kuj; Tus cab kuj raug muab faib ua ob pawg: ib qho yog qhov tsis zoo ntawm cov electrons,; Lwm hom yog lub qhov, zoo txaus. LCD teeb-emitting txujci yog kev siv ob hom kev sib tw hauv qee qhov kev mob ua ke, tso tawm ntawm lub zog hauv daim ntawv ntawm photon los ntawm lub teeb. Nws yuav ua raws li cov ntaub ntawv sib txawv, hluav taws xob thiab qhov chaw nyob hauv lub zog txawv, electron thiab qhov yuav ua tau raws li qhov siab qhov sib txawv ntawm qhov sib txawv yog txiav txim siab rau ob lub cab kuj nrog lub zog, nws muaj peev xwm tsim photons nrog sib txawv energies, uas tswj lub LED lub teeb tawm ntawm lub wavelength, thiab yog cov spectrum los yog xim.

Cov ntaub ntawv uas siv hauv LED mas tsuas yog 3A-5A compound compound semiconductors (xws li GaP, GaAs, GaN, AlInGaP, thiab lwm yam). Raws li yog vim li cas nws yuav tawm tau lub teeb ntawm cov xim sib txawv, nws yog LED nws tus kheej nyob ntawm cov ntaub ntawv, xws li: lub teeb liab nrog AlInGa (arsonium AlGaAs), ntsuab npab (Lin Huajia), xiav lub teeb nrog ZnS (zinc sulfide) los yog GaNN ( Indium gallium nitride) ... tos.

LED tau muab faib ua duab pom lub teeb thiab duab teeb ci ntsa iab emitting diode raws li nws lub luminous wavelength. Txoj cai luminescent yog siv cov electron thiab lub qhov nyob rau hauv ib qho kev siv hluav taws xob, yuav tso tawm dag zog hauv daim duab ntawm ib lub photon los ntawm lub teeb, thiab lub teeb emitting diode uas siv cov khoom siv rau semiconductor 3A, 5A ntsiab, xws li: GaAs, GaP, AlGaP , AlInGaP thiab lwm yam zoo li, cov pa tawm ntawm lub zog thiab kev ci ci rau kev siv cov ntaub ntawv sib txawv.

Qhov txawv ntawm LCD thiab LED

Piv nrog LCD cov teeb pom kev zoo, LED muaj ntau dua qhov zoo ntawm qhov kev ci ntsa iab, kev siv hluav taws xob, pom qhov muag thiab qhov hloov tshiab, uas tau raug tso tseg rau qhov kev taw qhia ntawm LED. Siv cov tshuab technology, koj tuaj yeem tsim muaj thinner, zog, dlaim phaj tshaj LCD.

1) LED thiab LCD zog noj piv ntawm 1:10, LED ntau zog.

2) LED muaj ntau zog dua, qhov ua tau zoo dua ntawm kev ua yeeb yaj kiab.

3) LED muab lub ntsej muag thoob plaws ntawm 160 degrees, koj tuaj yeem tso ntau hom ntawv, zauv, duab xim thiab cov ntaub ntawv qhia txog animation, koj tuaj yeem ua si TV, video, VCD, DVD thiab lwm yam xim video.

4) LED cov yeeb yaj duab ntawm ib lub caij ceev ceev yog 1000 zaug ntawm LCD LCD npo, tuaj yeem raug saib xyuas nyob rau hauv lub teeb, thiab hloov mus rau qis dua ntawm 40 degrees.

OLED-- organic teeb emitting diode

Nws thiab LED, tab sis tsuas yog ib tsab ntawv sib txawv, tab sis qhov tseeb ob piav txog txhua yam txawv. Peb txhua tus paub tias lub LCD vaj huam sib luag yog los ntawm lub teeb nrig, los ntawm kev siv cov kua siv lead ua kua molecules thiab tsim ntau yam xim, cov kua siv lead ua kua molecules lawv tus kheej tsis tuaj yeem tawm lub teeb, thiab LED hais txog tsuas yog rau cov teeb. Lub OLED nws tus kheej tau tawm ntawm lub teeb, thiaj tsis muaj kev teeb tsa. LED yog siv hauv cov ntaub ntawv hlau, thiab OLED yog siv cov khoom siv organic; Ib txhia ntau tshaj li ntawm OLED, nws tsis xav tau lub teeb yuav ua rau nws tus kheej luminous, zoo ib qho txawv, feem ntau yog nrog LED, yog muaj lub teeb ci ntsa iab tuaj yeem pom.

Nyob rau tam sim no, lub teeb ci tawm ntawm cov khoom siv yog cov khoom siv hauv nruab nrab cov ntaub ntawv, tsis yooj yim siv rau cheeb tsam loj thiab yuav tsum muaj cov khoom siv high-resolution (EX: screen), los daws cov teebmeem no yog nyob ntawm hom khoom siv cov khoom siv organic (cov ntaub ntawv muaj cov roj carbon monoxide ), Nws yog coated ntawm iav ntawv conductive, mus txog rau tam sim no. Koj tuaj yeem tso ntau hom wavelengths ntawm lub teeb.

OLED luminescence txujci

Cov ntsiab lus ntawm lub cev muaj zog thiab cov cai ntawm lub teeb emitting diode yog zoo ib yam li cov khoom siv tib yam, electron qhov nyob rau hauv lub teeb emitting txheej nrog electrons ntawm kev txaus siab xeev ntog rov qab mus rau hauv av hauv lub xeev, lub zog ntau tshaj tawm nyob rau hauv daim ntawv ntawm lub zog , Thiab ua tiav lub teeb ci. Yog li, tsuas yog hu rau OLED thiab PLED. OLED yog lub cev me me lub cev cov pa taws ua pa tawm diode, PLED yog lub cev ua kom lub cev muaj zog ntawm lub cev.

OLED qauv

Cov qauv ntawm cov organic teeb emitting diode raws li qhia hauv qab no, yog siv cov khoom siv tib qho, electron dawm hauv lub teeb-emitting txheej nrog lub xeev kev zoo siab los ntawm daim ntawv rov qab mus rau hauv av hauv lub xeev, lub zog tshaj hauv daim ntawv ntawm Yoj tso, yog li ua tiav txawv wavelength lub teeb emitting Cheebtsam tsim. OLED yog siv txhaj tshuaj electrons thiab qhov nruab nrab ntawm ob lub electrodes, thiab kev siv cov organic molecules los tsim kho, thiab ua kom muaj nuj nqi. Tus anode yog ITO conductive iav zaj duab xis, hauv daim ntawv evaporation, txuas rau cov iav los yog cov yas pob yas, cov cathode muaj Mg, Al, Li thiab lwm yam hlau. Hauv nruab nrab ntawm ob lub electrodes yog lub teeb emitting cheeb tsam ntawm ntau yam organic nyias nyias tsim, nrog rau qhov chaw txhaj tshuaj thiab qhov hloov mus rau thaj av, cov organic teeb emitting txheej thiab electron thauj txheej, qhov tseeb ntau, xav txawv txawv ntawm kev sib txawv, qee zaus Muaj lwm cov yeeb yaj duab.

OLED xim hom

Cov organic teeb emitting diode rau cov tshuab ntsuab yog qhov feem ntau paub tab, xiav lub teeb thiab lub teeb liab kom tau commercialized. Xim organic teeb emitting diode zaub yog muab faib ua duab, xim thiab xim, muaj yeeb yuj, yog li ntawm ntau qhov chaw monochrome cov cheeb tsam, txhua cheeb tsam yog tsim ntawm cov xim rov ua dua ib zaug; Pixel liab, xim ntsuab thiab xiav peb xim, pixel loj me me, qhov siab dua qhov kev daws teeb meem. Hauv daim ntaub ntawv tso cai, xim yog qhov tseem ceeb ntawm txoj kev ua lag luam.

Dab tsi yog qhov zoo ntawm OLED cov cuab yeej?

OLED yog lub teeb pom kev zoo ntawm lub teeb tsa hluav taws xob, lub npe hu ua laser zaub nrog lub teeb, hluav taws xob thiab lwm yam ntxwv, yog li pib ntawm 2003, lub tshuab ntaus ntawv tau muab siv rau hauv MP3 player, thiab rau DC thiab txawb xov tooj yog cov khoom , Yav tas los hauv qee qhov kev nthuav qhia pom tias qhov kev ntsuam xyuas OLED project. Tsis rau hauv daim ntawv thov theem. Tab sis qhov screen OLED muaj ntau yam tsis zoo ntawm LCD, yog li nws tau optimistic txog kev lag luam.

OLED daim ntawv thov

OLED yog siv los ntawm lub tsheb hom, cov xov tooj ntawm tes, cov game consoles, handheld portable mini computer, tus kheej digital assistant (PDA), lub suab audio thiab cov koob yees duab ... Lwm yam .. Lub neej yav tom ntej yuav yog los ntawm cov khoom siv hluav taws xob, 5 nti puv npo zaub ntau lawm, cov khoom xyaw organic txog kev txhim kho daim ntawv thov kev lag luam, kev daws teeb meem puv npo kev loj hlob ntawm kev loj me me, xws li ntse xov tooj txawb.

Nyob rau hauv cov kua hluav taws xob kua siv tam sim no, OLED muaj ntau yam zoo, xws li kev ua haujlwm ultra-thin, zoo seismic, lub rooj saib loj, lub sijhawm luv luv, tsawg kub, kev ua haujlwm zoo luminous thiab lwm yam. Nws yuav tsum raug sau tseg hais tias, txawm tias OLED tau maj mam paub zoo, tab sis tam sim no peb tsis pom ib thaj tsam loj ntawm OLED cov khoom tau teev tseg.
