COB LED Display Technology Analysis and Application Prospects

COB (Chip on Board) Zowonetsera za LED ndiukadaulo wotsogola womwe umakwaniritsa kuphatikiza kwakukulu ndikuchita bwino kwambiri polongedza mwachindunji tchipisi ta LED pama board ozungulira. Poyerekeza ndi zowonetsera zachikhalidwe za SMD (Surface Mount Device) LED, ukadaulo wa COB umapereka maubwino odalirika pakudalirika, kufanana kowala, komanso zowonera. M'zaka zaposachedwa, lakhala likugwiritsidwa ntchito kwambiri m'mawonetsero amalonda, zisudzo, komanso kuyang'anira{2}}pamwamba kwambiri.

Kuchokera pamawonekedwe aukadaulo, gawo lalikulu la COB LED zowonetsera zili m'mapaketi awo. Chipcho chimayikidwa mwachindunji ku gawo lapansi ndikutetezedwa ndi epoxy resin kapena silikoni, kuchepetsa kwambiri chiwerengero cha zolumikizira zogulitsira ndipo motero kulephera. Kapangidwe kameneka sikumangowonjezera kugwedezeka kwa chinthucho komanso kukana kwake komanso kumathetsa vuto la "kuwala kwakufa" lomwe limapezeka pazithunzi zachikhalidwe za LED. Kuphatikiza apo, ukadaulo wa COB umapereka mawonekedwe ang'onoang'ono a pixel, omwe amathandizira kuti aziwoneka bwino komanso atsatanetsatane, zithunzi zomveka bwino, zomwe zimapangitsa kuti zikhale zoyenera kuti anthu aziwonera pafupi{3}}pafupi.

Pankhani ya mawonekedwe owonetsera, mawonetsedwe a COB LED amapereka kusiyana kwakukulu komanso kutulutsa mitundu. Chifukwa chosanjikiza cholongedza chimagwira ntchito bwino kwambiri pamagetsi achiwiri, kugawa kuwala kumakhala kofanana kwambiri, kupeŵa "chinthu chonyowa" chomwe chimapezeka muzowonera zakale. Kuphatikiza apo, kuchuluka kwake kotsitsimutsa komanso kugwiritsa ntchito mphamvu pang'ono kumapangitsa kuti ikhale chisankho chabwino kwambiri chowonetsera zithunzi komanso kusunga mphamvu.

Pakadali pano, zowonetsera za COB LED zalowa pang'onopang'ono-m'misika yotsika mtengo monga malo opangira ma command centers,{1}}zapamwamba{1}}zogulitsa zotsika mtengo, ndi kujambula zithunzi zenizeni. Ndi kulumikizana kwa umisiri wa Mini/Micro LED, zowonetsera za COB zikuyembekezeka kuchepetsa kukula, kuwunikira, ndi kuwonjezera mphamvu zamagetsi, kukhala gawo lalikulu lachitukuko pamsika wawukulu-wowonetsa zenera. Ngakhale mtengo wake wopanga umakhalabe wokwera kuposa njira zachikhalidwe, mpikisano wamsika wa COB LED upitilira kukula pomwe ukadaulo ukukula komanso kukula.
