Iwo mapoka ediki-pitch maLED akawedzera, uye atanga kukwikwidza neDLP neLCD mumusika wemukati wekuratidzira. Zvinoenderana nedhata pachiyero chemusika wepasi rose wekuratidzira LED, kubva muna 2018 kusvika 2022, zvakanakira kuita zvediki-pitch LED kuratidza zvigadzirwa zvichave pachena, zvichigadzira maitiro ekutsiva echinyakare LCD uye DLP matekinoroji.
Indasitiri kugovera kwediki-pitch LED vatengi
Mumakore achangopfuura, madiki-pitch LEDs akawana kukurumidza kusimudzira, asi nekuda kwemitengo uye nenyaya dzehunyanzvi, parizvino ari kunyanya kushandiswa mundima dzehunyanzvi. Aya maindasitiri haana hanya nemitengo yechigadzirwa, asi anoda yakakwira mhando yekuratidzira, saka ivo vanokurumidza kutora musika mumunda weakakosha kuratidza.
Kuvandudzwa kwemadiki-pitch LEDs kubva kumusika wakatsaurwa wekuratidzira kuenda kumisika yekutengeserana neyevanhu. Mushure megore ra2018, sezvo tekinoroji inokura uye mutengo uchidzikira, madiki-pitch maLED akaputika mumisika yekuratidzira yekutengeserana semakamuri emusangano, dzidzo, nzvimbo dzekutengesa, uye mabhaisikopo. Iko kudiwa kwepamusoro-yekupedzisira madiki-pitch maLED mumisika yemhiri kwemakungwa kuri kukurumidza. Vanomwe vevasere vepamusoro vagadziri ve LED vanobva kuChina, uye vagadziri vasere vepamusoro vanoita 50.2% yemugove wemusika wepasi rose. Ini ndinotenda kuti sezvo denda idzva rekorona rinodzikama, misika yemhiri kwemakungwa ichakurumidza kusimuka.
Kuenzanisa kwediki-pitch LED, Mini LED, uye Micro LED
Iwo matatu ari pamusoro ekuratidzira matekinoroji ese akavakirwa padiki LED makristaro masisitimu sepixel inopenya mapoinzi, mutsauko uri pachinhambwe pakati pepedyo mwenje mabheji uye chip size. Mini LED uye Micro LED inowedzera kuderedza mwenje bead spacing uye chip size pahwaro hwediki-pitch maLEDs, ari iwo maitiro makuru uye kutungamira kutungamira kweramangwana rekuratidzira tekinoroji.
Nekuda kwemusiyano wehukuru hwechip, akasiyana siyana ekuratidzira tekinoroji masimu ekushandisa achave akasiyana, uye diki pixel pitch inoreva iri pedyo yekuona chinhambwe.
Kuongororwa kweDiki Pitch LED Packaging Technology
SMDndiko kudimburira kwesurface Mount mudziyo. Iyo isina chip chip inogadziriswa pabhaketi, uye magetsi ekubatanidza anogadzirwa pakati pezvakanaka uye zvisina kunaka electrodes kuburikidza nesimbi yesimbi. Iyo epoxy resin inoshandiswa kuchengetedza iyo SMD LED mwenje mabheji. Mwenje we LED unogadzirwa ne reflow soldering. Mushure mekunge mabheji akabatanidzwa nePCB kuti agadzire iyo unit unit module, iyo module inoiswa pane yakagadziriswa bhokisi, uye simba rekupa, control kadhi uye waya zvinowedzerwa kuti zvigadzire yakapedzwa LED kuratidza skrini.
Kuenzaniswa nemamwe mamiriro ekurongedza, zvakanakira zveSMD zvakaputirwa zvigadzirwa zvinodarika zvipingamupinyi, uye zvinoenderana nehunhu hwekudiwa kwemusika wepamba (kuita sarudzo, kutenga, uye kushandisa). Ndivo zvakare zvigadzirwa zvemazuva ese muindasitiri uye vanogona kukurumidza kugamuchira mhinduro dzebasa.
COBmaitiro ndeyekunamatira zvakananga iyo LED chip kuPCB ine conductive kana isiri-conductive glue, uye kuita waya bonding kuti uwane magetsi ekubatanidza (positive mounting process) kana kushandisa chip flip-chip tekinoroji (isina waya dzesimbi) kugadzira iyo yakanaka uye yakaipa. ma electrode ebhedhi remwenje akabatana zvakananga nePCB yekubatanidza (flip-chip tekinoroji), uye pakupedzisira iyo unit unit module inoumbwa, uye ipapo module inoiswa pane yakatarwa bhokisi, ine simba rekupa, control kadhi uye waya, nezvimwe. gadzira iyo yakapera LED kuratidza skrini. Chakanakira COB tekinoroji ndechekuti inorerutsa maitiro ekugadzira, inoderedza mutengo wechigadzirwa, inoderedza mashandisirwo emagetsi, saka tembiricha yepasi yekuratidzira inodzikiswa, uye musiyano unovandudzwa zvakanyanya. Izvo zvisingabatsiri ndezvokuti kuvimbika kunotarisana nezvinetso zvakakura, zvakaoma kugadzirisa mwenje, uye kupenya, ruvara, uye ruvara rweinki zvichiri kuoma kuita Kuenderana.
IMDinobatanidza N mapoka eRGB marambi mabhero kuita chidimbu chidiki kuita bhedhi remwenje. Main technical nzira: Yakajairika Yang 4 mu 1, Yakajairika Yin 2 mu 1, Yakajairika Yin 4 mu 1, Yakajairika Yin 6 mu 1, etc. Kubatsira kwayo kuri mune zvakanakira zvekubatanidza kurongedza. Saizi yemwenje yemwenje yakakura, kukwirisa kwepamusoro kuri nyore, uye diki dot pitch rinogona kuwanikwa, izvo zvinoderedza kuoma kwekugadzirisa. Kukanganisa kwaro ndekwekuti ikozvino maindasitiri cheni haina kukwana, mutengo wakakwira, uye kuvimbika kuri kutarisana nematambudziko makuru. Kugadzirisa hakuna kunaka, uye kuenderana kwekupenya, ruvara, uye ingi ruvara hakuna kugadziriswa uye inoda kuvandudzwa.
Micro LEDndeye kuendesa huwandu hukuru hwekero kubva kune yechinyakare LED arrays uye miniaturization kune yedunhu substrate kuti igadzire ekupedzisira-yakanaka-pitch LEDs. Hurefu hweiyo millimeter-level LED inowedzerwa kuderedzwa kusvika kune micron level kuti iwane Ultra-yakakwirira pixels uye yekupedzisira-yepamusoro resolution. Mune dzidziso, inogona kuchinjirwa kune akasiyana skrini saizi. Parizvino, tekinoroji yakakosha mubhodhoro reMicro LED ndeyekupaza kuburikidza neiyo miniaturization process tekinoroji uye tekinoroji yekufambisa. Kechipiri, tekinoroji yekufambisa firimu yakatetepa inogona kutyora muganho uye kupedzisa kuendesa batch, iyo inotarisirwa kudzikisa mutengo.
GOBIyo tekinoroji yekuvhara iyo yese pamusoro pepamusoro Mount modules. Iyo inoputira dhizaini yeakajeka colloid pamusoro pechinyakare SMD diki-pitch modules kugadzirisa dambudziko rechimiro chakasimba nekudzivirira. Mukukosha, ichiri SMD diki-pitch chigadzirwa. Kubatsira kwayo kudzikisa mwenje yakafa. Inowedzera simba rinopesana nekudengenyeka uye kuchengetedzwa kwepamusoro kwemarambi. Izvo zvisingabatsiri ndezvokuti zvakaoma kugadzirisa mwenje, deformation ye module inokonzerwa ne colloidal stress, reflection, local degumming, colloidal discoloration, uye kugadziriswa kwakaoma kweiyo virtual welding.
