Cov zaub coj ua qauv muaj keeb kwm ntev. Los ntawm thawj zaug hluav taws xob ua ke hauv silicon carbide muaju rau qhov chaw tam sim no uas coj cov ntxaij vab tshaus uas coj los ntawm cov neeg txawj ntse thiab kev ua haujlwm nyuaj. Raws li kev tsim cov chaw tsim khoom ntawm muaj tswv yim LED zaub cov txiaj ntsig ntawm kev txhawb nqa cov txiaj ntsig LED, thiab kev lom zem thiab kev lom zem ua si. Tom qab ntawd, txhawm rau pab kom ntau tus neeg kom nkag siab txog kev txhim kho keeb kwm ntawm LED Zaub, peb yuav tshawb txog keeb kwm kev txhim kho ntawm cov zaub ua ke nrog koj hauv kab lus no
Lub hauv paus pib ntawm LED Tshuab (1907-1960s)
Ib qho kev sib tw coj LED yog ib lub teeb ua qauv zoo nkauj uas muaj qhov tam sim no ua rau pom kev zoo, yog li muab cov ces kaum kev pabcuam thiab lub neej ntev. Lawv muab kev txhawb nqa rau ntau cov ntawv thov, suav nrog cov ntawv tshaj tawm, chaw sib tw ntau pob, muag khoom muag thiab tsheb thauj mus los tsheb thauj khoom. Txawm li cas los xij, qhov ntxov tshaj plaws LED thev naus laus zis tsis yog xim zoo nkauj li nws tau pom tam sim no. Lub hauv paus ntawm LED Tshuab tau nteg nyob rau xyoo 1907 thaum British Engineer nyob rau hauv ib lub teeb crystal, ceeb toom lub teeb emission nyob rau hauv cov hluav taws xob txhawb nqa. Qhov kev tshawb pom qhov tseeb no, txawm hais tias tseem ceeb, tseem yog theoretical vim muaj cov ntaub ntawv tsawg. Xyoo 1927, Lavxias teb sab Oleg los ntawm thawj qhov ua tau LED, sau nws lub teeb-emitting zog, tab sis kev siv cov ntawv thov lag luam tseem tsis tau ua tau.
Ib lub sijhawm pivotal tau los xyoo 1962 thaum Nick Holyak, tus kws ua haujlwm nyob rau ntawm hluav taws xob dav dav, tsim lub ntsej muag liab pom siv cov tshuaj ntsuab arsenide phosphide. Qhov kev sib tsoo no tau qhib los tsim lub teeb pom kev, tsis zoo li cov khoom siv hluav taws xob ua ntej dhau los hauv cov khoom siv hluav taws xob zoo li lub laij thiab cov khoom siv digital. Txawm li cas los xij, cov kev ntxov no tau txwv rau lub teeb liab, muaj qhov ci qis, thiab feem ntau yog haum rau qhov ntsuas tau yooj yim.
Cov Milestones tseem ceeb:
- Xyoo 1907: Henry Yauxej tau tawm tsam cov hluav taws xob hluav taws xob hluav taws xob hluav taws.
- Xyoo 1927: Oleg losyev tsim thawj cov cuab yeej LED.
- Xyoo 1962: Nick Holyak tsim cov liab liab coj.
- Cov kev txwv: Cov zis monochromatic, qis lub ci, txwv rau cov haujlwm qhia tau.
Qhov tshwm sim ntawm puv-xim LED cov lus qhia (1970s-1990s)
Kev nce qib hauv cov ntaub ntawv kev tshawb fawb thaum xyoo 1970 tau nthuav tawm ntsuab thiab tseem tsis muaj cov kab uas xav tau rau cov xim xiav. Qhov tawg tau txog xyoo 1993 thaum Suji Nakamamura, ua haujlwm ntawm Nichia Corporation, tsim lub siab-ci ci xiav led siv gallium nitride. Lub tswv yim tshiab no, uas tau txais Nakamura lub Nobel nqi zog nyob rau xyoo 2014, qhib liab, ntsuab, thiab xiav (RGB) ua ke rau cov xim puv ntoob. Hauv 1995, phosphor txheej ntawm xiav leds tsim lub teeb dawb, ntxiv dav dav LED kev siv.
Xyoo 1977, engineer James Mitchell tsim cov vijtsam LED thawj zaug, ib kauj ruam tseem ceeb rau kev tsis muaj xiav LEDs. Los ntawm 1990s, muaj cov muaj xiav LEDs Facilitated kev tsim cov xim puv nkaus RGB LED qhia, muaj peev xwm ntawm rendering dynamic duab thiab videos. Kev txhim kho hauv kev tsav tsheb npav, tswj cov tshuab tswj khoom, thiab ua kom zoo dua cov teeb pom kev haum rau kev ua lag luam zoo li cov kev sib tw thiab cov paib qhia pej xeem.
Cov Milestones tseem ceeb:
- Xyoo 1970: Green thiab daj LEDs tsim.
- 1993: Shuji Nakamura tau caw xiav LED.
- 1995: Dawb cov coj tsim kev siv phosphor txheej.
- Xyoo 1977: James Mitchell tsim cov thawj-xim LED screen.
- 1990s: Puv-Xim RGB nthuav tawm nrog kev txhim kho daws teeb meem thiab kev tswj hwm.
Kev Lag Luam thiab Thoob Plaws Kev Cauj (2000s-2010)
Qhov 2000s cim kev hloov mus rau kev ua lag luam raws li nplua-suab LED cov lus qhia tsis pub txo pixel placing, tseem ceeb txhim kho cov duab clarity. Pixel suab, qhov kev ncua deb ntawm LED pixels, txo qis los ntawm ntau dua 5 hli rau hauv qab no 1mm, ua rau cov yeeb yaj kiab zoo tshaj plaws rau kev saib ze. Qhov kev tshaj tawm no nthuav dav cov ntawv thov sab hauv, nrog cov chav tswj hwm, thiab huab cua tsis zoo rau kev siv hauv cov ntawv cim npe, chaw ua haujlwm, thiab kev thauj mus los.
LED qhia tau txais kev tshaj tawm txog kev xaiv li LCD thiab ntshav vim lawv qhov kev ua kom ruaj khov, thiab kev yoog tau zoo. Los ntawm xyoo 2010s, lawv tau dhau los ua kev sib txuas lus zoo, tsav los ntawm kev txhim kho hauv kev sib piv, thiab raug cov xim.
Cov Kev Tsim Nyog:
- Cov tshuaj ntsuab zoo me ntsis kev siv hluav taws xob txo pixel suab rau sub -1 hli.
- Kev hloov pauv ntawm cov ntawv nyeem-raws li cov lus txhais cov yees duab siab.
- Cov Kev Siv: Sab Hauv Tsev (Khw Muag Khoom, Ua Yeeb Yam) thiab Sab Nraum Zoov (Chaw Tswj Khoom, Kev Tshaj Tawm).
- Txhim kho qhov kaj, txawv, thiab ib puag ncig ruaj khov.
Tsis ntev los no Kev Tsim Kho thiab Kev Tshaj Tawm Tshaj Tawm (2010s nthuav qhia)
Xyoo 2010 tau qhia tawm tau yooj yim thiab nkhaus LED cov lus qhia, ua haujlwm los ntawm cov yeeb yaj kiab-raws li cov yeeb yaj kiab thiab cov qauv tsim qauv. Cov kev txhawb nqa no tau tso cai rau kev sib xyaw ua ke, xws li cov cuab yeej siv hnav, cov ntaub qhwv tsheb, thiab cov khoom siv tsis huv hauv cov tsev khaws puav pheej thiab chaw ua si. Lub Rauv ntawm lub nroog ntse tau tsav qhov kev saws me me ntawm cov qauv hloov tshiab, txhawb kev ua haujlwm tiag tiag, thiab cov ntaub ntawv-tsav kev tshaj tawm.
Hauv kev sib piv, OLED cov lus qhia, uas siv cov organic sib txuas rau cov khoom siv hluav taws xob, muab cov khoom siv thinner thiab zoo dua qub hauv cov ntawv thov hwm sab hauv tsev. Txawm li cas los xij, LED qhia kev ua kom zoo nyob rau hauv qhov ci ci, thoj, thiab tus nqi-ua hauj lwm zoo rau kev loj thiab siv sab nraum zoov. Kev nthuav tawm tshiab suav nrog micro-LED thev naus laus zis, uas muaj cov kev daws teeb meem siab dua thiab ua tau zoo, thiab pob tshab siv rau cov khw muag khoom lag luam tshiab.
TSEEM CEEB LUAM:
- Hloov tau thiab cov khoom pov tseg rau cov ntoo, tsheb, thiab cov kev tsis sib haum.
- Ai \/ iot kev koom ua ke rau cov ntsiab lus tiag tiag thiab kev txuag hluav taws xob.
- LED thiab OLED: Leds Excel nyob rau hauv lub ci ci thiab durabe; Oleds nyob rau hauv sib piv thiab nyias nyias.
- Tawm: micro-coj, pob tshab qhia, thiab cov ntaub ntawv ntse.
Cov Milestones thiab Cov Neeg Pioneers
Cov Evolution ntawm LED tawm yog txhais los ntawm cov cim tseem ceeb thiab kev koom tes los ntawm cov nuj nqis tseem ceeb:
- Xyoo 1907: Henry Yauxej tau tawm tsam cov hluav taws xob hluav taws xob hluav taws xob hluav taws.
- Xyoo 1927: Oleg los ntawm thawj lub LED ntaus ntawv.
- Xyoo 1962: Nick Holyak caw tau pom cov LED.

Cov pioneers no, txhawb nqa los ntawm kev nce qib hauv cov ntaub ntawv hauv cov ntaub ntawv thiab engineering, hloov pauv mus rau hauv lub pob kws ntawm kev pom kev siv thev naus laus zis.
Cov FAQ
Q1: Dab tsi yog qhov sib txawv ntawm LED thiab OLED cov lus qhia?
LED cov ntaub ntawv siv cov semiconductor diodes donges rau lub teeb pom kev zoo, muab siab ci thiab ruaj khov rau kev loj thiab sab nraum zoov cov ntawv thov. OLED qhia txog cov organic sib txuas, muab kev sib piv zoo dua thiab thinner profiles tab sis tsis tshua ruaj khov thiab ntau tus nqi.
Q2: Thaum twg yog thawj lub LED Zaub Screen tsim?
Thawj LED Zaub Screen tau tsim los ntawm James Mitchell hauv xyoo 1977, pib txwv rau ib qho xim vim tsis muaj xiav LEDs.
Q3: Yuav ua li cas muaj pixel suab muaj kev cuam tshuam zoo tshaj sijhawm?
Txo hauv Pixel lub suab txij li tshaj 5 hli kom qis dua ntawm 1 hli muaj cov lus pom zoo thiab pom kev txhais cov video siab thiab ze.
Q4: yog LED cov lus qhia tseem hloov zuj zus tseem niaj hnub no?
Yog lawm, kev nce qib tsis tu ncua nyob rau hauv micro-coj, hloov cov ntxaij vab tshaus, thiab cov ntawv thov Ai \/ iot tau nthuav dav cov nroog ntse, hnav, thiab cov kab thiab cov pa tsis huv.
