1. Nhanganyaya
Yakajairwa LED yekuratidzira pani ine dziviriro isina kusimba kubva kune hunyoro, mvura, uye guruva, kazhinji kusangana nezvinotevera nyaya:
Ⅰ. Munzvimbo dzine hunyoro, mabheti makuru emapikseli akafa, mwenje wakaputsika, uye “gonye” zviitiko zvinowanzoitika;
Ⅱ. Munguva yekushandiswa kwenguva refu, mhepo inogadzirisa mhute uye mvura inoputika inogona kukanganisa marambi e LED;
Ⅲ. Kuunganidzwa kweguruva mukati mechidzitiro kunotungamira mukupisa kwakashata uye kuwedzera kuchembera kwekrini.
Kune yakajairika yemukati yekuratidzira LED, mapaneru e LED anowanzo kuendeswa mune zero-chikanganiso mamiriro pafekitori. Zvisinei, mushure menguva yekushandiswa, nyaya dzakadai sezviedza zvakaputsika uye kupenya kwemutsara zvinowanzoitika, uye kukanganiswa kusingatarisirwi kunogona kukonzera madonhwe emwenje. Panzvimbo dzekuisa, zvisingatarisirwe kana zvisingatarisirwi nharaunda dzimwe nguva zvinogona kusangana, senge zvikanganiso zvakakura zvinokonzerwa nekusiyana kwetembiricha kubva kumhepo inofefetera inovhuvhuta yakananga padhuze, kana hunyoro hwepamusoro huchikonzera kuwedzera kwemazinga ekukanganisa kwescreen.
Zvemukatiyakanaka pitch LED kuratidzamutengesi ane ongororo yehafu-pagore, kugadzirisa nyaya dzakadai sehunyoro, huruva, kudhumhana, uye mitengo yekukanganisa, uye kuvandudza mhando yechigadzirwa uku uchidzikisa mushure mekutengesa-sevhisi mutoro uye mutengo zvinonetsa zvakanyanya kune vanopa LED kuratidza.
Mufananidzo 1. Yakashata pfupi-circuit uye column lighting phenomenon ye LED kuratidza
2. RTLED's AOB Coating Solution
Kuti tigadzirise nyaya idzi nemazvo,RTLEDinosuma iyo AOB (Advanced Optical Bonding) coating solution. AOB coating tekinoroji skrini inotsaura machubhu e LED kubva kunze kwemakemikari kusangana, kudzivirira hunyoro uye kupindira kweguruva, zvakanyanya kuwedzera mashandiro ekudzivirira kwedu.LED skrini.
Mhinduro iyi yakavakirwa pane yazvino yemukati yepamusoro-yakamisikidzwa LED yekuratidzira dhizaini maitiro, inobatanidza isina musono neiyo iripo SMT (Surface Mount Technology) mitsara yekugadzira.
Mufananidzo 2. Schematic dhayagiramu yezvigadzirwa zvekuputira pamusoro (chiedza chepamusoro)
Iwo chaiwo maitiro ndeaya anotevera: mushure mekunge mabhodhi e LED agadzirwa uchishandisa tekinoroji yeSMT uye akwegura kwemaawa makumi manomwe nemaviri, chivharo chinoiswa pabhodhi repamusoro, chichigadzira chidziviriro chinovhara mapini ekuitisa, achivadzivirira kubva kune unyoro uye mhute mhedzisiro, sezvakaratidzwa. mufananidzo 3.
Kune general LED kuratidza zvigadzirwa zvine chiyero chekudzivirira che IP40 (IPXX, yekutanga X inoratidza kuchengetedzwa kweguruva, uye yechipiri X inoratidza kuchengetedzwa kwemvura), AOB coating tekinoroji inosimudzira zvakanyanya mwero wekudzivirira wenzvimbo ye LED, inopa kudzivirira kudhumhana, inodzivirira madonhwe emwenje. , uye inoderedza iyo yakazara skrini yekukanganisa mwero (PPM). Iyi mhinduro yakasangana nemusika kudiwa, yakakura mukugadzirwa, uye haiwedzere zvakanyanya mutengo wese.
Mufananidzo 3. Schematic diagram yemaitiro ekuputira pamusoro
Uyezve, maitiro ekudzivirira ari kumashure kwePCB (Yakadhindwa Circuit Board) inochengetedza yakapfuura matatu-uchapupu nzira yekudzivirira pendi, kuvandudza mwero wekudzivirira kuseri kwebhodhi redunhu kuburikidza nekupfapfaidza maitiro. Chidziviriro chekudzivirira chinoumbwa pamusangano wakabatanidzwa (IC) pamusoro, kudzivirira kukundikana kwezvikamu zvedunhu zvakabatanidzwa mumutambo wekufambisa.
3. Kuongororwa kweAOB Features
3.1 Zvinhu Zvinodzivirira Pamuviri
Zvimiro zveAOB zvekudzivirira zvinotsamira pane yepasi pekuzadza coating, iyo ine bonding maitiro akafanana nesolder paste asi iri insulating zvinhu. Iyi inonamira yekuzadza inoputira pasi pese peiyo LED, ichiwedzera kugona kwekubata pakati pe LED nePCB. Miedzo yeLabhoritari inoratidza kuti yakajairwa SMT solder side-push simba ndeye 1kg, nepo mhinduro yeAOB inowana kudivi-kusundidzira simba re4kg, kugadzirisa matambudziko ekudhumhana panguva yekuisa uye kudzivirira padhi dhizaini inoita kuti mapuranga emarambi asagadziriswe.
3.2 Chemical Protective Properties
AOB's makemikari ekudzivirira zvimiro anosanganisira matte akajeka ekudzivirira anofukidza iyo LED uchishandisa yakakwirira-polymer zvinhu zvinoshandiswa kuburikidza nanocoating tekinoroji. Kuomarara kweiyo 5 ~ 6H pachiyero cheMohs, ichivharira unyoro neguruva, kuve nechokwadi chekuti marambi haakanganisirwe nenharaunda panguva yekushandiswa.
3.3 Zvitsva Zvakawanikwa Pasi Dziviriro Zvivakwa
3.3.1 Kuwedzera Kwekutarisa
Iyo matte yakajeka inodzivirira layer inoita selenzi pamberi peiyo LED, ichiwedzera mwenje emission angle yemwenje we LED bead. Miedzo inoratidza kuti kona yekuburitsa mwenje inogona kuwedzerwa kubva pa140 ° kusvika 170 °.
3.3.2 Yakavandudzwa Kusanganiswa Kwechiedza
SMD pamusoro-yakaiswa maturusi ndiwo mapoinzi emwenje masosi, ayo ane granular kana achienzaniswa nepamusoro pechiedza masosi. AOB coating inowedzera musara wegirazi rakajeka paSMD LEDs, kuderedza granularity kuburikidza nekufungisisa uye refraction, kuderedza moiré mhedzisiro, uye kuwedzera chiedza musanganiswa.
3.3.3 Inopindirana Black Screen
Isingawirirani PCB bhodhi ingi mavara agara ari dambudziko kune SMD kuratidzwa. AOB coating tekinoroji inogona kudzora ukobvu uye ruvara rweyekupfekedza layer, kugadzirisa zvine mutsindo nyaya yezvisingaenderane PCB inki mavara pasina kurasikirwa nemakona ekuona, kunyatsogadzirisa nyaya yekushandisa akasiyana mabhechi ePCB mabhodhi pamwe chete, nekuvandudza kugona kwekutakura.
3.3.4 Kuwedzera Kusiyanisa
Nanocoating inobvumira kunyatso kudzora, ine inodzoreka zvinhu kuumbwa, kuwedzera kusviba kweiyo skrini yepasi ruvara uye kugadzirisa musiyano.
4. Mhedziso
AOB coating tekinoroji inovhara yakafumurwa magetsi conductive pini, zvinodzivirira kudzivirira kukanganisa kunokonzerwa nehunyoro uye guruva, uku ichipa chengetedzo yekudhumhana. Nekudzivirirwa kwekuzvimiririra kweAOB nanocoating, ma LED ekukanganisa mazinga anogona kudzikiswa kusvika pazasi 5PPM, achivandudza zvakanyanya goho rekrini uye kuvimbika.
Yakavakirwa paSMD LED kuratidza hwaro, iyo AOB maitiro inotora mabhenefiti ekureruka kwerambi rimwe chete kugadzirisa kweSMD, uku ichinyatso optimize nekusimudzira mashandisiro emushandisi uye kuvimbika maererano nehunyoro, guruva, nhanho yekudzivirira, uye kufa kwemwenje mwero. Kubuda kweAOB kunopa sarudzo yekutanga yemukati mekuratidzira mhinduro uye chiitiko chakakosha mukushanduka kwe LED kuratidza tekinoroji.
RTLED itsva katatu-uchapupu mukatidiki pitch LED kuratidza-isina mvura, isina guruva uye bump-proof - AOB Display.Bata nesu izvozvikuti uwane quota yepamutemo.
