Mu 2023, akuyembekezeka kuti msika wogulitsa wa LED ku China udzafika pa 75 biliyoni yuan. Uyu ndi mtolankhani wa "China Electronics News" mu Novembala 3-4 yemwe adachita semina ya 18 ya chitukuko cha mafakitale a LED ndi ukadaulo komanso semina ya 2023 yaukadaulo wosinthana ndi chitukuko cha mafakitale. Akatswiri pamsonkhanowo adanenanso kuti ndi chitukuko cha ukadaulo wa Mini/Micro LED komanso kukhwima kwa zinthu zazing'ono, zotsatira za kuphatikizana kwa mafakitale zikuonekera kwambiri, ndipo mabizinesi odutsa malire alowa pamsika, mawonekedwe amtsogolo a mafakitale kapena adzasinthidwa.
Motsogozedwa ndi mbadwo watsopano wa ukadaulo wazidziwitso, makampani a LED akulowa mu gawo la zatsopano, kusintha ndi kukonza, komanso chitukuko chapamwamba. Guan Baiyu, mlembi wamkulu wa China Semiconductor Lighting /LED Industry and Application Alliance, adanenanso potsegulira kuti m'zaka makumi awiri zapitazi kuyambira 2003, China yakhala ikuyambitsa zinthu zatsopano mu zida za LED, magetsi a LED, chiwonetsero ndi magetsi akumbuyo, ndipo makampaniwa apeza chidziwitso chofunikira ndikufufuza lamulo la chitukuko cha mafakitale.
"Makampani onse a LED ku China apanga chip yoyambira ya LED, phukusi, driver IC, makina owongolera, magetsi, zida zothandizira kupanga ndi zinthu zina, komanso unyolo wina wathunthu wamafakitale, miyezo ya zachilengedwe zamafakitale, kuti pakhale chitukuko ndi kukwezedwa kwina, adayika maziko." Wapampando wa nthambi ya China Optical optoelectronics Industry Association, Guan Jizhen, adatero. Malinga ndi ziwerengero za nthambi ya Display Application Branch ya China Optical Optoelectronics Industry Association, gawo la msika wa zinthu zowonetsera zamkati ndi zakunja lasintha kwambiri m'zaka zaposachedwa, ndipo gawo la zinthu zowonetsera zamkati lawonjezeka chaka ndi chaka, zomwe zimapangitsa kuti zikhale zoposa 70% ya zinthu zonse zomwe zilipo pachaka. Kuyambira 2016, chiwonetsero cha LED chaching'ono chakhala chikukula kwambiri ndipo chakhala chinthu chachikulu pamsika wowonetsera. Pakadali pano, msika wonse wa zinthu zowonetsera zamkati ndi zakunja za LED ndi woposa 40% ya zinthu zonse zazing'ono ndi zapakati.
Mtolankhani adaphunzira pamsonkhanowo kuti ukadaulo wa COB womwe ukugwiritsidwa ntchito pano, ukadaulo wa Mini/Micro LED display, kuwombera kwa LED virtual ndi njira zina pang'onopang'ono zakhala zowonjezera zatsopano pakukula kwa msika wa LED. Monga njira yapamwamba kwambiri yopangira ukadaulo, COB pang'onopang'ono yakhala njira yofunika kwambiri yopangira ukadaulo wazinthu pansi pa chitukuko cha mtunda wa ma LED screen, ndipo gulu la opanga ndi kukula kwake zikukula mofulumira. Kuyambira pomwe msika wa Mini LED backlight udalowa mumsika mu 2021, kuchuluka kwa kukula kwa pachaka kwa compound kwafika pa 50%; Micro LED ikuyembekezeka kugwiritsidwa ntchito kwambiri mkati mwa zaka ziwiri kuchokera pamene ukadaulo wofunikira monga kusamutsa kwakukulu wakula. Ponena za kuwombera kwa LED virtual, ndi kuchepetsa mtengo ndi kukonza bwino kwa kuwombera kwa ukadaulo, kuwonjezera pa gawo la mafilimu ndi wailesi yakanema, imagwiritsidwanso ntchito kwambiri pamitundu yosiyanasiyana, kuwulutsa pompopompo, kutsatsa ndi zochitika zina.
Msonkhanowu ukutsogoleredwa ndi China Optical Optoelectronics Industry Association, ndipo umathandizidwa ndi China Optical Optoelectronics Industry Association Optoelectronic Devices Branch ndi LED Display Application Branch.
