Nguva pfupi yadarika, Kambani hombe yeB2B chikamu chakaburitsa chizvarwa chitsva chenyeredzi mepu akateedzana COB diki spacing.Saizi yechigadzirwa che LED mwenje-emitting chip ingori 70μm, uye yakanyanya kudiki-emitting pixel nzvimbo inovandudza musiyano.
Muchokwadi, vese vagadziri vakuru vari kuwedzera yavo R&D uye hunyanzvi hweCOB tekinoroji uye kubata musika.Nekudaro, pamusoro pekubvumirana kuti "COB ndiyo huru-yekupedzisira nzira yekurongedza tekinoroji", kuchine misiyano yakakura muMiP neCOB tekinoroji mukati meindastiri.
Kutonga kwenguva refu-uye pfupi-yenguva yehunyanzvi nzira
Sezvo COB inotambanukira yakananga kumatinji mahombe uye MiP inofamba ichienda kumatinji madiki, pachange paine imwe nhanho yemakwikwi pakati penzira mbiri dzehunyanzvi.Asi izvozvi, hausi hukama hwehupenyu-kana-rufu.Naizvozvo, mukati meimwe nguva yenguva uye mukati meimwe chinhambwe, COB, MiP, uye IMD zvichagara pamwe chete.Aya ese matanho anodiwa pakuvandudza tekinoroji.
Kubva pakuona kwenguva refu, COB ikozvino yakagadzira yakakosha yekutanga-mufambisi mukana, uye makambani nemhando dzakapinda zvizere mumusika;uyezve, COB ine hunhu hwechisikigo hwehupfupi uye hwakareruka maitiro ekubatanidza;apo maitiro ekutamisa vanhu vakawanda Mushure mekuwana budiriro maererano nemutengo uye mutengo, pane mukana wekukunda maguta nematunhu.
Mumusika wemazuva ano, high-definition yakakura masikirini anoshandisa akawanda LED zvigadzirwa nediki spacing (pazasi P2.5).Ramangwana rinotevera, icharamba ichikura yakananga kune yakakwira pixel density uye diki pixel pitch, iyo inosimudzira COB kuti ive yakakosha kutungamira kwe LED kurongedza tekinoroji kusimudzira nekugadzirisa.
COB yekuvandudza mamiriro uye maitiro
Zvinoenderana nedata kubva kune ane mvumo yekambani yeruzivo, muhafu yekutanga ye2023, kutengesa kwediki-pitch LED kuratidzwa mu mainland China kwakasvika 7.33 bhiriyoni, zvishoma kuwedzera 0.1% gore-pa-gore;nzvimbo yekutumira yakasvika 498,000 square metres, gore negore kuwedzera kwe20.2%.Pakati pavo, kunyangwe SMD (kusanganisira IMD) tekinoroji ndiyo yakakura, chikamu cheCOB tekinoroji inoramba ichikura.Pakazosvika chikamu chechipiri che2023, chikamu chekutengesa chasvika 10.7%.Chikamu chemusika chese muhafu yekutanga yegore chakawedzera neinenge 3 muzana mapoinzi zvichienzaniswa nenguva imwe cheteyo.
Parizvino, musika wechigadzirwa wediki-pitch LED kuratidza COB tekinoroji inopa anotevera maitiro:
Mutengo: Avhareji mutengo wemuchina wese wadzikira kusvika pasi pe50,000 yuan/㎡.Mutengo weCOB yekurongedza tekinoroji wadzikira zvakanyanya, zvekuti avhareji mutengo wemusika wediki-pitch LED kuratidza COB zvigadzirwa wadzikawo zvakanyanya kupfuura kare.Muhafu yekutanga ya2023, mutengo wepakati wemusika wakadzikira ne28%, uchisvika paavhareji mutengo we45,000 yuan/㎡.
Spacing: Simbisai pane P1.2 uye pazasi zvigadzirwa.Kana iyo point pitch iri pasi peP1.2, COB yekurongedza tekinoroji ine mukana mumutengo wakazara wekugadzira;COB inodarika 60% yezvigadzirwa zvine mapiche eP1.2 uye pazasi.
Kushanda: kunyanya kutarisa mamiriro, anonyanya kudiwa muminda yehunyanzvi.Iyo diki-pitch LED inoratidzira yeCOB tekinoroji ine hunhu hwepamusoro density, kupenya kwepamusoro, uye tsanangudzo yepamusoro.Mukutarisa mamiriro, kutumirwa kweCOB kunodarika makumi mana muzana;ivo vanonyanya kuenderana nezvinodiwa nevatengi muminda yehunyanzvi, kusanganisira simba redhijitari, chekufambisa, mauto, mari uye mamwe maindasitiri.
Forecast: Pakazosvika 2028, COB ichaverengera anopfuura makumi matatu muzana ediki-pitch LEDs.
Kuongorora kwakadzama kunoratidza kuti sezvo COB yekurongedza tekinoroji inoumba kudyidzana kwakanaka muzvinhu zvitatu: kufambira mberi kwehunyanzvi hweindasitiri, kuwedzera kwehuwandu hwekugadzira uye kuwedzera kwekuda kwemusika, zvishoma nezvishoma inove yakakosha chigadzirwa tekinoroji mukusimudzira diki-pitch mudiki-pitch LED. kuratidza indasitiri.
Pakazosvika 2028, tekinoroji yeCOB ichaverengera zvinopfuura makumi matatu muzana zvekutengesa muChina diki-pitch LED (pazasi P2.5) musika wekuratidzira.
Kubva pamaonero ebhizinesi, makambani mazhinji anobatanidzwa mukuratidzira kwe LED haatarise pane imwe nzira.Vanowanzo kufambira mberi mune zvese COB uye MiP nzira.Zvakare, senzvimbo yekudyara-yakanyanya uye tekinoroji-yakanyanya maindasitiri munda, kushanduka kweiyo LED kuratidza indasitiri hakutevedze zvizere kuita kwekutanga musimboti we "mari yakanaka inodzinga mari yakaipa".Mafungiro uye simba rekambani yekambani inogonawo kukanganisa ramangwana rechipiri Kuvandudzwa kwemaitiro ekugadzira nzira.
