1. Nhanganyaya
Sezvo ma LED ekuratidzira skrini maapplication achiwedzera kupararira, zvinodiwa zvemhando yechigadzirwa uye kuita kwekuratidzira kwakawedzera. Traditional SMD tekinoroji haichakwanisa kuzadzisa zvinodiwa zvemamwe maapplication. Naizvozvo, vamwe vagadziri vari kuchinjika kune nzira nyowani dzekuisa senge COB tekinoroji, nepo vamwe vachivandudza paSMD tekinoroji. GOB tekinoroji iiteration yeyakagadziridzwa SMD encapsulation process.
Indasitiri yekuratidzira ye LED yakagadzira nzira dzakasiyana dzekuisa, kusanganisira COB LED kuratidza. Kubva pane yekutanga DIP (Direct Insertion Package) tekinoroji kune SMD (Surface-Mount Device) tekinoroji, ipapo kusvika pakubuda kweCOB (Chip paBhodhi) encapsulation, uye pakupedzisira kuuya kweGOB (Glue paBhodhi) encapsulation.
Ko tekinoroji yeGOB inogona kugonesa zvikumbiro zvakakura zve LED kuratidza skrini? Ndeapi maitiro atingatarisira mune ramangwana musika kuvandudzwa kweGOB? Ngatienderere mberi.
2. Chii chinonzi GOB Encapsulation Technology?
2.1GOB LED kuratidzainodzivirira yakanyanya LED kuratidza sikirini, inopa kusapinda mvura, hunyoro-uchapupu, isingaite, inodzivirira guruva, isingadziviriri, yebhuruu inodzivirira chiedza, inodzivirira munyu, uye anti-static masimba. Izvo hazvikanganisi kukanganisa kupisa kana kurasikirwa kwekupenya. Kuongorora kwakadzama kunoratidza kuti glue rinoshandiswa muGOB rinotobatsira mukupisa kupisa, kuderedza kutadza kwema LEDs, kuwedzera kugadzikana kwechiratidziro, uye nekudaro kuwedzera hupenyu hwayo.
2.2 Kuburikidza neGOB kugadzirisa, iyo yaimbove granular pixel mapoinzi paGOB LED skrini yechiso inoshandurwa kuita yakatsetseka, yakati sandara nzvimbo, ichiwana shanduko kubva panzvimbo yemwenje sosi kuenda pamusoro pechiedza sosi. Izvi zvinoita kuti mwenje we LED wepaneru mwenje uwedzere yunifomu uye mhedzisiro yekuratidzira kujeka uye kujeka. Iyo inosimudzira zvakanyanya kona yekuona (inoda kusvika 180 ° yakatwasuka uye yakatwasuka), inobudirira kubvisa moiré mapatani, inovandudza zvakanyanya kusiyana kwechigadzirwa, inoderedza kupenya uye kupenya kwemhedzisiro, uye inoderedza kuneta kwekuona.
3. Chii chinonzi COB Encapsulation Technology?
COB encapsulation inoreva kubatanidza zvakananga chip kuPCB substrate yekubatanidza magetsi. Yakaunzwa zvakanyanya kugadzirisa dambudziko rekupisa kupisa kwemadziro evhidhiyo ye LED. Kuenzaniswa neDIP uye SMD, COB encapsulation inoratidzwa nekuchengetedza nzvimbo, kurerutswa encapsulation mashandiro, uye inoshanda yekupisa manejimendi. Parizvino, COB encapsulation inonyanya kushandiswa mukatiyakanaka pitch LED kuratidza.
4. Ndezvipi Zvakanakira COB LED Display?
Ultra-yakaonda uye Chiedza:Zvinoenderana nezvinodiwa nevatengi, mabhodhi ePCB ane hukobvu kubva pa0.4 kusvika 1.2mm anogona kushandiswa, kuderedza huremu kusvika padiki sechikamu chimwe chete muzvitatu chezvigadzirwa zvechinyakare, zvichidzikisa zvakanyanya zvimiro, zvekufambisa, uye mutengo weinjiniya kune vatengi.
Impact uye Pressure Resistance:COB LED inoratidzira inoputira iyo LED chip yakananga munzvimbo ine concave yePCB board, yobva yavhara nekuirapa ne epoxy resin glue. Pamusoro penzvimbo yemwenje inobuda, ichiita kuti ive yakatsetseka uye yakaoma, isingabatike, uye isingapfeke.
Wide Viewing Angle:COB encapsulation inoshandisa isina kudzika tsime spherical mwenje emission, ine yekuona kona yakakura kupfuura 175 madhigirii, padyo ne180 madhigirii, uye ine yakanakisa optical diffused chiedza mhedzisiro.
Kubvisa Kupisa Kwakasimba:COB LED skrini inoputira mwenje paPCB board, uye foil yemhangura paPCB board inokurumidza kuitisa kupisa kwepakati pechiedza. Ukobvu hwemhangura foil yePCB board ine zvakaomesesa zvinodikanwa, zvakasanganiswa negoridhe-plating maitiro, zvinopotsa kubvisa kuomarara kwechiedza. Nokudaro, kune zviedza zvishomanana zvakafa, zvichiwedzera zvikuru hupenyu.
Kupfeka-Kudzivirira uye Nyore Kuchenesa:COB LED skrini pamusoro peiyo mwenje poindi inobuda kuita yakatenderera, ichiita kuti iite yakatsetseka uye yakaoma, isingabatike uye isingapfeki. Kana poindi yakaipa ikaonekwa, inogona kugadziriswa point nepoint. Iko hakuna mask, uye guruva rinogona kucheneswa nemvura kana jira.
Zvese-Mamiriro Ekunze Kunaka:Katatu kudzivirira kurapwa kunopa yakasarudzika mvura, hunyoro-uchapupu, corrosion-proof, dustproof, anti-static, oxidation, uye UV kuramba. Inogona kushanda zvakajairika munzvimbo dzetembiricha kubva -30 ° C kusvika 80 ° C.
5. Ndeupi Musiyano Uripo Pakati peCOB neGOB?
Musiyano mukuru pakati peCOB neGOB uri mukuita. Kunyangwe COB encapsulation ine nzvimbo yakatsetseka uye inodzivirirwa iri nani pane yechinyakare SMD encapsulation, GOB encapsulation inowedzera glue application process pachiratidziro, ichiwedzera kugadzikana kwemarambi eLED uye kuderedza zvakanyanya mukana wekudonha kwemwenje, zvichiita kuti igadzikane.
6. Ndechipi Chinonyanya Kubatsira, COB kana GOB?
Iko hakuna mhinduro chaiyo yekuti ndeipi iri nani, COB LED kuratidza kana GOB LED kuratidza, sezvo kunaka kweiyo encapsulation tekinoroji kunoenderana nezvinhu zvakasiyana. Chinonyanya kutariswa ndechekuti iwe unoisa pamberi kushanda kwemarambi e LED kana kudzivirira kunopihwa. Imwe neimwe encapsulation tekinoroji ine zvayakanakira uye haigone kutongwa pasi rose.
Paunosarudza pakati peCOB neGOB encapsulation, zvakakosha kufunga nezvenzvimbo yekuisa uye nguva yekushanda. Izvi zvinhu zvinokanganisa kudzora mutengo uye mutsauko mukuita kwekuratidzira.
7. mhedziso
Ose ari maviri GOB uye COB encapsulation matekinoroji anopa akasiyana mabhenefiti e LED kuratidza. GOB encapsulation inowedzera kuchengetedza uye kugadzikana kwemarambi e LED, ichipa yakanakisa kusapinda kwemvura, guruva, uye anti-kurovera zvivakwa, ukuwo ichivandudza kupisa kupisa uye kuita kwekuona. Kune rimwe divi, COB encapsulation inokunda mukuchengetedza-nzvimbo, kutonga kwakanaka kwekupisa, uye kupa mhinduro isina kuremerwa, isingaite. Sarudzo pakati peCOB neGOB encapsulation inoenderana nezvinodiwa uye zvakakosha zvenzvimbo yekuisa, sekugara, kudzora mutengo, uye kuratidza mhando. Tekinoroji yega yega ine simba rayo, uye sarudzo inofanirwa kuitwa zvichibva pakuongorora kwakadzama kwezvinhu izvi.
Kana iwe uchiri kuvhiringidzika nezve chero chikamu,taura nesu nhasi.RTLEDyakazvipira kupa yakanakisa LED kuratidza mhinduro.
