Chiwonetsero chapachaka cha "China International Optoelectronic Exposition" monga chiwonetsero chapadziko lonse lapansi cha masikelo ndi mphamvu zama optoelectronics chidzatsegulidwa bwino ku Shenzhen Convention and Exhibition Center kuyambira pa Seputembara 4 mpaka 7, 2019, ndi malo owonetsera 110,000m2. Ndi mutu wa "kuyang'ana pa ntchito za optoelectronic ndikuthandizira makampani kuti agwirizane", chiwonetserochi chikusonkhanitsa makampani oposa 2,000 optoelectronic kunyumba ndi kunja kuti awonetsere zamakono zamakono ndi zinthu zatsopano za optoelectronic ndi optoelectronic applications. Zikuyembekezeka kukopa alendo opitilira 70,000 akatswiri.
China International Optoelectronic Expo ndi chiwonetsero chambiri chamakampani opanga ma optoelectronic okhala ndi sikelo yayikulu komanso chikoka. Zimakhudza makina a optoelectronic optical communication, laser, infrared, precision optics, optoelectronic innovation, kusakanikirana kwa asilikali ndi anthu, photoelectric sensing, data center ndi zina zotero. Monga chiwonetsero chaukatswiri chomwe chimakhudza gulu lonse la ma optoelectronics, CIOE China Optical Expo yakhala nsanja yosanja pakukulitsa msika ndikukweza mabizinesi ambiri. Zimaperekanso bizinesi yokhazikika kuti makampani apeze matekinoloje atsopano ndi zinthu komanso kumvetsetsa mwayi wamsika. Pulatifomu yaukadaulo yosinthana zaukadaulo ndi maphunziro.
