Cov pawg ntawm me-suab LED tau nce siab, thiab lawv tau pib sib tw nrog DLP thiab LCD hauv kev ua lag luam tso saib sab hauv tsev. Raws li cov ntaub ntawv ntawm cov teev ntawm cov lag luam thoob ntiaj teb LED zaub, txij xyoo 2018 txog 2022, cov txiaj ntsig zoo ntawm cov khoom siv hluav taws xob me me LED cov khoom lag luam yuav pom tseeb, ua rau muaj kev hloov pauv hloov tsoos LCD thiab DLP thev naus laus zis.
Kev lag luam faib ntawm cov me-suab LED cov neeg yuav khoom
Xyoo tsis ntev los no, cov suab paj nruag me me tau ua tiav txoj kev loj hlob sai, tab sis vim yog cov nqi thiab cov teeb meem kev siv tshuab, tam sim no lawv siv nyob rau hauv kev tshaj lij zaub. Cov kev lag luam no tsis nkag siab txog cov nqi khoom, tab sis xav tau cov zaub lag luam zoo, yog li lawv ceev nrooj nyob hauv kev lag luam hauv kev nthuav qhia tshwj xeeb.
Kev tsim kho me me suab thaj LED tawm los ntawm cov khoom lag luam muag zaub rau kev ua lag luam thiab kev lag luam tub luam. Tom qab xyoo 2018, raws li thev naus laus zis thev naus laus zis thiab nqi qis, me me suab paj nruag LED tau tawg lawm hauv kev ua lag luam cov zaub lag luam xws li chav sib tham, kev kawm, khw khw, thiab tsev ua yeeb yam. Qhov kev thov rau siab loj me me-LED hluav taws xob ntau hauv cov khw muag khoom txawv teb chaws yog kev ua kom sai. Xya ntawm lub ntiaj teb sab saum toj yim tus hluav taws xob LED yog los ntawm Tuam Tshoj, thiab lub kaum yim tuam ntxhab suav txog 50.2% ntawm cov lag luam hauv ntiaj teb. Kuv ntseeg hais tias thaum kev tawm tshiab tshiab tswj hwm, kev ua lag luam txawv teb chaws yuav sai sai.
Sib piv cov me-suab LED, Mini LED, thiab Micro LED
Qhov saum toj no peb cov thev naus laus zis yog txhua yam raws li cov khoom siv hluav taws xob me me ntawm LED siv hluav taws xob raws li cov ntsiab lus pixel luminous, qhov sib txawv lus dag hauv qhov kev ncua deb ntawm cov teeb txawb nyob ib sab thiab nti ua qhov loj me. Mini LED thiab Micro LED ntxiv txo cov teeb hlaws teeb pom kev zoo thiab nti loj rau ntawm lub hauv paus ntawm me-pitch LEDs, uas yog cov qauv hluav taws xob tseem ceeb thiab kev txhim kho kev taw qhia ntawm cov thev naus laus zis zaub yav tom ntej.
Vim tias qhov sib txawv hauv nti loj, ntau yam tso npe thov technology teb yuav muaj qhov sib txawv, thiab lub dav me me pixel txhais tau tias pom ze dua.
Kev Tshawb Xyuas Me Me Ntaus LED Ntim Tshuab
SMDyog cov ntawv sau ntawm saum npoo ntaus ntawv. Qhov liab qab liab qab yog tsau rau ntawm txoj hlua khi, thiab qhov hluav taws xob txuas yog tsim los ntawm qhov zoo thiab tsis zoo electrodes los ntawm cov hlau hlau. Epoxy resin siv los tiv thaiv SMD LED teeb hlaws. Lub teeb ci LED yog tsim los ntawm reflow soldering. Tom qab cov hlaws dai txuas nrog rau PCB los ua qhov teeb pom kev lag luam module, lub teeb tsa raug tso rau ntawm lub thawv ntawv ruaj khov, thiab lub hwj huam mov, tswj daim npav thiab xaim txuas ntxiv kom tsim ua tiav cov vijtsam LED zaub.
Piv nrog rau lwm cov teeb meem ntim khoom, qhov zoo ntawm SMD ntim cov khoom ntim ntau dua qhov tsis txaus ntseeg, thiab yog nyob ntawm tus yam ntxwv ntawm kev thov kev lag luam hauv tsev (kev txiav txim siab, kev tsim khoom, thiab siv). Lawv kuj yog cov khoom lag luam tseem ceeb hauv kev lag luam thiab tuaj yeem txais cov lus teb tau txais kev pabcuam sai.
COBcov txheej txheem yog kom ncaj qha rau cov LED nti rau lub PCB nrog lub ntsej muag lossis cov kua nplaum tsis zoo, thiab ua cov hlau txuas kom ua tiav cov hluav taws xob txuas (cov txheej txheem zoo ntawm kev sib tw) lossis siv cov chip flip-chip technology (tsis muaj cov xov hlau) ua qhov zoo thiab tsis zoo hluav taws xob ntawm lub teeb hlaws txuas ncaj qha rau hauv kev sib txuas ntawm PCB txuas (flip-chip technology), thiab thaum kawg cov qauv tsim teeb tsa tau tsim, thiab tom qab ntawd cov teeb tsa raug teeb tsa rau ntawm lub npov ruaj ruaj, nrog cov fais fab, tswj daim npav thiab xaim, thiab lwm yam. daim ntawv ua tiav LED cov vijtsam zaub. Qhov kom zoo dua ntawm COB thev naus laus zis yog tias nws ua cov txheej txheem tsim khoom yooj yim, txo cov nqi ntawm cov khoom, txo lub zog siv, yog li cov zaub hauv tshav kub tau txo, thiab qhov sib piv tau zoo heev. Qhov tsis zoo yog tias kev ntseeg tau ntsib cov teeb meem ntau dua, nws nyuaj rau kev kho lub teeb, thiab qhov ci ci, xim thiab number case xim tseem nyuaj rau ua kom tsis xwm yeem.
IMDsib xyaw nrog N pawg ntawm RGB lub teeb hlaws rau hauv ib koog me kom tsim lub teeb cig. Lub ntsiab txheej txheem tseem ceeb: Cov Yam Qub 4 nyob rau hauv 1, Hom Yin 2 hauv 1, Hom Yin 4 hauv 1, Hom Yin 6 hauv 1, thiab lwm yam. Nws qhov kom zoo dua yog qhov zoo ntawm kev sib xyaw ua ke ntim. Lub teeb hlaws dai loj dua, cov nplaim saum npoo tau yooj yim dua, thiab cov pob hluav taws xob me me tuaj yeem ua tiav, uas txo cov teeb meem nyuaj ntawm kev saib xyuas. Nws qhov tsis zoo yog tias qhov kev lag luam tam sim no tsis zoo tag nrho, tus nqi yuav siab dua, thiab kev ntseeg siab tau ntsib ntau dua kev cov nyom. Kev txij nkawm tsis yooj yim, thiab qhov sib xws ntawm ci ci, xim, thiab xim xim tsis tau daws teeb meem thiab xav tau kev txhim kho ntxiv.
Micro LEDyog hloov mus rau qhov ntau ntawm cov chaw nyob los ntawm tsoos LED arrays thiab miniaturization rau hauv Circuit Court substrate los ua ultra-fine-pitch LEDs. Qhov ntev ntawm lub millimeter-theem LED yog ntxiv txo mus rau qib micron kom ua tiav ultra-siab pixels thiab ultra-siab daws teeb meem. Hauv txoj kev xav, nws tuaj yeem hloov kho rau ntau cov npo ntau yam. Tam sim no, thev naus laus zis thev naus laus zis hauv kev pom zoo ntawm Micro LED yog tawg los ntawm cov txheej txheem miniaturization thev naus laus zis thiab kev siv tshuab loj. Qhov thib ob, qhov nyias zaj duab xis hloov tshuab tuaj yeem tsoo los ntawm qhov loj me thiab ua tiav cov pob xa mus, uas xav kom txo tus nqi.
KHWVyog lub thev naus laus zis los npog tag nrho saum npoo ntawm cov qauv module. Nws encapsulates txheej txheej ntawm cov pob tshab colloid nyob rau saum npoo ntawm cov tshuaj SMD me me-pitch cov tshuab los daws qhov teeb meem ntawm cov duab muaj zog thiab kev tiv thaiv. Hauv ntsiab, nws tseem yog SMD cov khoom lag luam me me. Nws qhov kom zoo dua yog txo cov teeb tuag. Nws nce lub zog los tiv thaiv kev poob siab thiab kev tiv thaiv kev tiv thaiv ntawm lub teeb hlaws. Nws qhov tsis zoo yog tias nws nyuaj rau kev kho lub teeb, kev rhuav tshem ntawm cov qauv tshwm sim los ntawm kev ntxhov siab colloidal, qhov cuam tshuam, hauv zos kev puas tsuaj, colloidal hloov kho, thiab qhov nyuaj kho ntawm lub vuam virtual.
