1. mawu oyamba
Kusintha kosalekeza kwaukadaulo waukadaulo wa LED kumatipangitsa kuchitira umboni kubadwa kwa chiwonetsero chazithunzi cha LED.Koma kodi chiwonetsero chazithunzi chabwino cha LED ndi chiyani?Mwachidule, ndi mtundu wa chiwonetsero cha LED chogwiritsa ntchito ukadaulo wapamwamba kwambiri, wokhala ndi kachulukidwe ka pixel kwambiri komanso mawonekedwe abwino kwambiri amitundu, zomwe zimakulolani kumizidwa muphwando lowoneka bwino komanso mitundu yowala.Chotsatira, nkhaniyi ifotokoza zaukadaulo, madera ogwiritsira ntchito komanso momwe katukuko kakang'ono ka ma LED akuwonekera, ndikupangitsa kuti musangalale ndi dziko lodabwitsa la chiwonetsero cha LED!
2. Kumvetsetsa ukadaulo wapakatikati wa zowonetsera bwino za LED
2.1 Tanthauzo Labwino la Pitch
Fine pitch LED chiwonetsero, monga momwe dzinalo likusonyezera, ndi mtundu wa mawonetsedwe a LED omwe ali ndi ma pixel ochepa kwambiri, omwe amadziwika ndi mtunda wa pakati pa ma pixel omwe ali pafupi kwambiri kotero kuti diso la munthu silingathe kusiyanitsa ma pixel a LED omwe amawoneka patali. motero kumapereka chithunzithunzi chosavuta komanso chomveka bwino.Poyerekeza ndi zowonetsera zachikhalidwe za LED, zowonetsera zowoneka bwino za LED zimadumphadumpha mu kachulukidwe ka pixel ndi kukonza, zomwe zimalola kumveka bwino komanso mawonekedwe amtundu wowona.
2.2 Kodi P-value (Pixel Pitch) ndi chiyani
P-value, mwachitsanzo, pixel pitch, ndi imodzi mwazofunikira zoyezera kuchuluka kwa ma pixel a chiwonetsero cha LED.Imayimira mtunda pakati pa ma pixel oyandikana nawo, omwe nthawi zambiri amayezedwa mu millimeters (mm.) Kuchepa kwa P-mtengo, kucheperako mtunda pakati pa ma pixel, kukwezeka kwa pixel, motero kuwonetsetsa bwino.Zowonetsera bwino za LED nthawi zambiri zimakhala ndi P-values yaying'ono, monga P2.5, P1.9 kapena ngakhale yaying'ono, zomwe zikutanthauza kuti amatha kuzindikira ma pixel ochulukirapo pamalo ang'onoang'ono owonetsera, ndikuwonetsa chithunzi chapamwamba.
2.3 Miyezo ya Fine Pitch (P2.5 ndi pansipa)
Nthawi zambiri, muyezo wamawonekedwe abwino a LED ndi P-value ya 2.5 ndi pansi.Izi zikutanthawuza kuti kusiyana pakati pa ma pixel ndi kochepa kwambiri, komwe kungathe kuzindikira kuchuluka kwa pixel ndi kuwonetsetsa kwakukulu.Kuchepa kwa mtengo wa P ndiko, kukwezera kachulukidwe ka mapikseli a kuwala kwa LED, ndipo zotsatira zowonetsera zidzakhala bwino.
3. Makhalidwe Aukadaulo
3.1 Kusamvana kwakukulu
Chiwonetsero chabwino cha LED chili ndi kachulukidwe kakang'ono kwambiri ka pixel, kamene kamatha kuwonetsa ma pixel ochulukirapo pamalo ochepera a zenera, motero amazindikira kusamvana kwakukulu.Izi zimabweretsa tsatanetsatane komanso zithunzi zenizeni kwa wogwiritsa ntchito.
3.2 Mlingo Wotsitsimula Kwambiri
Zowonetsa bwino za LED zimakhala ndi liwiro lotsitsimutsa mwachangu, zomwe zimatha kusinthira zithunzi makumi kapena mazana kambiri pamphindikati.Kutsitsimula kwakukulu kumatanthauza chithunzi chosalala, chomwe chimachepetsa kuzunzika ndi kutsetsereka kwa zithunzi, ndikupereka mawonekedwe omasuka kwa owonera.
3.3 Kuwala Kwambiri ndi Kusiyanitsa
Zowonetsa zowoneka bwino za LED zimapereka kuwala kwakukulu komanso kusiyanitsa kwakukulu, ngakhale m'malo owala.Kaya m'nyumba kapena kunja, kumveka bwino ndi kuwonekera kwa chithunzicho kumatha kusungidwa, kupereka magwiridwe antchito abwinoko pazowonetsa zotsatsa, ziwonetsero za siteji ndi zochitika zina.
3.4 Kusasinthika kwamitundu ndi kuberekana
Chiwonetsero cha LED chowoneka bwino chimakhala ndi kusasinthika kwamitundu komanso kutulutsa kwamitundu, komwe kumatha kubwezeretsanso mtundu wazithunzi zoyambirira.Kaya ndi yofiira, yobiriwira kapena yabuluu, imatha kusunga yunifolomu yamtundu ndi machulukitsidwe.
4. Njira yopanga
4.1 Kupanga chip
Pakatikati pa chiwonetsero cha LED chowoneka bwino ndi chipangizo chake chapamwamba cha LED, Chip cha LED ndi gawo lotulutsa kuwala, lomwe limatsimikizira kuwala, mtundu ndi moyo wa chinsalu.Njira yopanga chip imaphatikizapo kukula kwa epitaxial, kupanga chip ndi njira zoyesera.
Zida za LED zimapangidwa pagawo lapansi kudzera muukadaulo wa kukula kwa epitaxial kenako ndikudula tchipisi tating'onoting'ono.Njira yopangira chip yapamwamba kwambiri imatsimikizira kuti tchipisi ta LED timakhala ndi kuwala kwambiri komanso moyo wautali.
4.2 Packaging Technology
Tchipisi za LED zitha kutetezedwa bwino ndikugwiritsidwa ntchito pambuyo pa encapsulation.Njira yopangira encapsulation imaphatikizapo kukonza chipangizo cha LED pa bulaketi ndikuchiyika ndi epoxy resin kapena silicone kuti chiteteze chip ku chilengedwe chakunja.Ukadaulo wapamwamba wa encapsulation ukhoza kupititsa patsogolo magwiridwe antchito komanso kudalirika kwa tchipisi ta LED, motero kukulitsa moyo wautumiki wa chiwonetserochi.Kuphatikiza apo, zowonetsera zowoneka bwino za LED nthawi zambiri zimagwiritsa ntchito ukadaulo wa pamwamba mount (SMD) kuyika ma LED ang'onoang'ono angapo mugawo limodzi kuti akwaniritse kachulukidwe ka pixel yapamwamba komanso mawonekedwe abwinoko.
4.3 Kusintha kwa Module
Chiwonetsero chabwino cha LED chimapangidwa ndi ma module angapo a LED ophatikizidwa palimodzi, gawo lililonse ndi gawo lodziwonetsera lodziyimira palokha.Kulondola komanso kusasinthika kwa kuphatikizika kwa ma module kumakhudza kwambiri mawonekedwe omaliza.Njira yophatikizira yolondola kwambiri ya module imatha kuwonetsetsa kusalala kwa chiwonetserocho komanso kulumikizana kosasunthika, kuti muzindikire magwiridwe antchito athunthu komanso osalala.Kuphatikiza apo, kuphatikizika kwa ma module kumaphatikizanso kupanga maulumikizidwe amagetsi ndi kutumiza ma sign kuti zitsimikizire kuti gawo lililonse lingagwire ntchito limodzi kuti likwaniritse bwino kwambiri chiwonetsero chonse.
5. Zochitika Zogwiritsira Ntchito Zowonetsera Zabwino Pitch LED
5.1 Kutsatsa malonda
5.2 Msonkhano ndi Chiwonetsero
5.3 Malo Osangalatsa
5.4 Mayendedwe ndi Malo Othandizira Boma
6.kumaliza
Pomaliza, zowonetsera zowoneka bwino za LED zikuwonetsa kupita patsogolo kwakukulu kwaukadaulo wowonetsera, kupereka zithunzi zomveka bwino, zowoneka bwino komanso zowonera bwino.Ndi kachulukidwe kawo ka pixel kwambiri komanso kupanga kolondola, ndi oyenera kugwiritsa ntchito zosiyanasiyana, kuyambira kutsatsa malonda kupita kumalo osangalatsa.Pamene ukadaulo ukupita patsogolo, zowonetsera izi zitha kukhala zofunikira kwambiri pamoyo wathu watsiku ndi tsiku, ndikukhazikitsa miyezo yatsopano yazinthu zama digito ndi kulumikizana kowonekera.
Ngati muli ndi mafunso ambiri okhudzana ndi mawonekedwe abwino a LED, chondeLumikizanani nafe, tidzakupatsirani njira zowonetsera za LED.
