Abstract:Mune ramangwana, musika wekushandisa uri kubuda weLED kuratidza skrini, kunze kwenzvimbo yekamuri yekusangana uye misika yefirimu neterevhizheni, inosanganisirawo misika yakadai semakamuri ekutarisisa, kunze madiki-pitch skrini, nezvimwe. Nekuderera kwemitengo uye kufambira mberi kwehunyanzvi, nzvimbo zhinji dzekushandisa dzichagadzirwa.Zvisinei, panewo matambudziko.Kudzikiswa kwemitengo uye zvichemo zvekuda zvidiki zvinopindirana uye kusimudzirana.
Muna 2020, nekuda kwekukanganisa kweCCIDID-19, kudiwa kwemusika wepasi rose kwe LED kwakadzikira zvakanyanya, kunyanya mumisika yekunze seEurope neUnited States.Zviitiko zvekutengesa uye zviitiko zvemitambo zvadzikira zvakanyanya, izvo zvichakanganisa kudiwa kwekupedzisira kwezviratidziro zve LED.Mainland China ndiyo huru pasi roseChiratidziro che LEDchigadziko chekugadzira, uye inosanganisirawo yepakati nepamusoro peiyo chip, kurongedza uye kutsigira maindasitiri.Kudzikira kwakaerekana kwechido chemhiri kwemakungwa kwakanganisa hukama hwakasiyana hwemaindasitiri edzimba kune akasiyana madhigirii.
Mumunda wezvigadzirwa zvakapedzwa zvekuratidzira, kudiwa kwemusika kwakawira muchidimbu muhafu yekutanga yegore.Kutanga kubva pakupera kwe3Q20, kudiwa mumusika weChinese kwapora zvishoma nezvishoma.Kwegore rose, zvichienderana nehuwandu hwekutanga hweTrendForce, saizi yemusika wepasi rose muna 2020 i5.47 bhiriyoni emadhora ekuAmerica, ichidzika 14% gore-pagore.Panyaya yekutarisa kwemaindasitiri, chikamu chemusika chevagadziri vasere vakuru panosvika 2020 chichawedzera kuwedzera, kusvika pa56%.Kunyanya mumusika wechiteshi, mari yemakambani anotungamira inoramba ichikura.
Kubva pakuona kwekuparadzana, chikamu chepakati chidiki uye zvigadzirwa zvepakati zvakanaka zvakawedzera kuwedzera, nechikamu chinodarika 50%.Pakati pezvigadzirwa zviduku-zvishoma, maererano nehuwandu hwekubuda, P1.2-P1.6 ine chikamu chepamusoro chekubuda kwehuwandu, inopfuura 40%, inoteverwa neP1.7-P2.0 zvigadzirwa.Tichitarisira kuna 2021, iyo Chinese musika kudiwa inotarisirwa kuenderera mberi iyo yakasimba mamiriro e4Q20.Kunyangwe mamiriro edenda mumusika wepasi rose achienderera mberi, hurumende ichatorawo matanho anoenderana.Kukanganisa kwehupfumi kuchave kwakaderera pane gore rapfuura.Kudiwa kunotarisirwa kupora.Musika wekuratidzira we LED unotarisirwa kusvika 6.13 bhiriyoni emadhora ekuAmerica, gore-pa-gore kuwedzera kwe12%.
Mumunda wemutyairi ICs, musika wepasi rose uchasvika 320 miriyoni US madhora muna 2020, kuwedzera kwe6% gore-pagore, zvichiratidza maitiro ekukura achipokana nemaitiro.Pane zvikonzero zvikuru zviviri.Kune rumwe rutivi, sezvo kugadziriswa kunowedzera, iyo huru yekuratidzira pitch inoramba ichiderera, izvo zvinokurudzira kuwedzera kwakasimba kwekuda kwekuratidzira mutyairi ICs;nerumwe rutivi, huwandu hwekugadzira hwe8-inch wafers huri kushomeka, uye machira anodiwa zvakanyanya.Zvigadzirwa zvemagetsi zvemagetsi zvine purofiti yakakwira mabheti zvakakonzera kuwanda kwemutyairi ICs, zvichikonzera kuwedzera kwemitengo yezvimwe zvigadzirwa zveIC mutyairi.
Mutyairi IC iindasitiri yakatarisana zvakanyanya, uye vagadziri vashanu vepamusoro vane chikamu chemusika chakabatanidzwa chinodarika 90%.Tichitarisira 2021, kunyangwe huwandu hwekugadzira hwe8-inch wafer machira hwawedzerwa, kudiwa kwemusika kwemagetsi emagetsi senge 5G nharembozha nemotokari zvichine simba.Pamusoro pezvo, kudiwa kwehombe-saizi yepaneru mutyairi ICs zvakare yakasimba.Naizvozvo, kushomeka kwemutyairi IC kugadzirwa kwesimba kuchiri kunetsa kudzikisira, mitengo yeIC inoramba ichikwira, uye saizi yemusika inotarisirwa kuwedzera kukura kusvika 360 mamirioni emadhora emadhora, kuwedzera kwe13%.
Tichitarisira kumikana yekuvandudza kweramangwana rezviratidziro zve LED, nzvimbo yekusangana yekamuri uye firimu nemusika weterevhizheni zvinotarisirwa kuve nzvimbo dzakakosha dzekushandisa dzekuratidzira kwe LED.
Chekutanga ndiko kushandiswa kwenzvimbo yekamuri yekusanganira.Parizvino, zvigadzirwa zvakajairwa zvinosanganisira mapurojekita, maratidziro e LED uye hukuru-hukuru LCD skrini.Zviratidziro zve LED zvinonyanya kushandiswa mumakamuri makuru emisangano, uye makamuri madiki emisangano haasati abatanidzirwa muhukuru.
Nekudaro, muna 2020, vagadziri vazhinji vakagadzira LED zvese-mune-imwe zvigadzirwa.LED-in-ones inotarisirwa kutsiva mapurojekita.Ikozvino kudiwa kwepasirese kwemapurojekita emakamuri emusangano angangoita mamirioni mashanu pagore.
Maererano neongororo yakaitwa neTrendForce, huwandu hwekutengesa kwe LED-in-ones muna 2020 hwakapfuura 2,000 units, ichiratidza kukurumidza kukura maitiro, uye kune nzvimbo huru yekukura mune ramangwana.Dambudziko hombe remichina-mune-imwe musangano inyaya yemutengo.Mutengo uripo uchiri kudhura, uye kudzikiswa kwemutengo kunoda kutsigirwa kwezvinodiwa zvekupedzisira.
Zvishandiso zviri mumusika wemufirimu neterevhizheni zvinonyanya zvinosanganisira matatu makuru mashandisirwo: bhaisikopo remitambo yemitambo, kutamba kumba kwetiyeta, uye kumberi-kumashure mabhodhi ekupfura firimu neterevhizheni.Mumusika wemubhaisikopo, zvigadzirwa zvine hukama zvakatangwa zvine maitiro akanaka ekuratidzira, asi zvipingamupinyi zvikuru ndezvekuti mutengo wakanyanya kukwira uye zvikwaniriso zvinonetsa kuwana.Mumusika weimba yetiyeta, izvo zvinodikanwa zviri nyore, uye hunhu hwakakodzera haudiwi.Dambudziko guru imari.Parizvino, mutengo wezviratidziro zve LED unoshandiswa mudzimba dzemabhaisikopo wakapetwa kakapetwa mutengo wemapurojekita epamusoro.
Iyo yekumberi-yekupedzisira skrini yekugadzira firimu uye terevhizheni inotsiva yechinyakare girini skrini musika, iyo inogona kuchengetedza mutengo uye nguva yefirimu neterevhizheni mushure mekugadzirwa.Iyo yekumashure skrini yekupfura haidi yakakwira nzvimbo.Iyo mainstream spacing yezvigadzirwa zvazvino ndeye P1.2-P2.5, asi iyo yekuratidzira mhedzisiro yakakwira, inoda yakakwira dynamic range imaging (HDR), yakakwirira furemu refresh rate (HFR) uye yakakwirira High Greyscale, izvi zvinodiwa zvichawedzera iyo yakazara. mutengo wekuratidzira.
Mune ramangwana, musika uri kusimukira we LED kuratidza zvikumbiro, kuwedzera kune yataurwa pamusoro pekamuri yemusangano nzvimbo uye firimu uye terevhizheni misika, inosanganisirawo misika yakaita semakamuri ekutarisa uye ekunze madiki-pitch skrini.Sezvo mitengo inodonha uye tekinoroji ichifambira mberi, nzvimbo zhinji dzekushandisa dzichakanganiswa.Developed.Zvisinei, panewo matambudziko.Kudzikiswa kwemitengo uye zvichemo zvekuda zvidiki zvinopindirana uye kusimudzirana.Maitiro ekurima nekusimudzira misika iri kusimukira ichave yakakosha musoro weiyo LED kuratidza indasitiri mune ramangwana.
