Sezvo musika weiyo micro-pitch uchiramba uchipisa, 4K uye 8K yakakwira-tsanangudzo zvishoma nezvishoma yave chiyero chitsva chekuratidzira kwe LED, uye kudiwa kwemusika kwepamusoro-tsanangudzo kuratidza kuri kuwedzera.COB , ndiani angawana kuzivikanwa kwemusika mumugwagwa we micro-pitch display? Aya matekinoroji ekurongedza ane zvawo zvakanakira, asi nguva yemicro-pitch yasvika. Seyanguard yeiyo micro-spacing era, COB yave kuzivikanwa zvakanyanya nemusika. Nekukura kukuru kweiyoP0.9 Chiratidziro che LED musika gore rino, COB yave protagonist yemukati yakakwira tsanangudzo ye LED kuratidza. Mune ramangwana rinoonekwa, sezvo nzvimbo inova diki Kuenda pasi, COB ichave iyo huru chigadzirwa iteration nzira yemusika.
Nekuenderera mberi kwekufambira mberi kweCOB tekinoroji, gore rinomicro-pitch LED kuratidza , common cathode, flip-chip, mass transfer uye mamwe mazwi ave kutarisa kwenhau kakawanda, ndeapi aya matekinoroji? Inoona sei ramangwana reCOB tekinoroji micro-pitch yakananga?
Common cathode tekinoroji - kuchengetedza simba, kukwirira kwepamusoro uye kuderera kwesimba rekushandisa
Iyo yakajairwa LED inoratidzira inotora yakajairwa anode (positive danda) magetsi emagetsi modhi, ikozvino inoyerera kubva kuPCB bhodhi kuenda kune mwenje mabhero, uye akajairika anode mwenje mabhero uye anoenderana mutyairi IC uye RGB mwenje mabheji anoshandiswa kune akabatana magetsi. Common cathode inoreva iyo yakajairika cathode (negative danda) magetsi emagetsi nzira, uchishandisa yakajairwa cathode mwenje mabhero uye yakasarudzika yakajairika cathode mutyairi IC chirongwa, R uye GB inopihwa simba rakaparadzana, uye ikozvino inopfuura nepakati pemarambi uye yozoenda kuIC. cathode. Mushure mekushandisa iyo yakajairwa cathode, isu tinokwanisa kupa zvakananga akasiyana ma voltages zvinoenderana nezvinodiwa zvakasiyana zve diode yevoltage, saka hapana chikonzero chekugadzirisa voltage divider resistor kudzikisa simba rekushandisa kwechikamu ichi, asi kuratidza kupenya uye kuratidza. mhedzisiro haina kukanganiswa, uye kuchengetedza kwesimba kunowedzerwa ne25% ~ 40%.
Ndeupi mutsauko uripo pakati pedhiraivha yedhiraivha yeyakajairwa cathode uye yakajairika anode?
Chokutanga pane zvose, nzira yekutyaira yakasiyana. Kutyaira kwakajairwa kunoreva kuti ikozvino yekutanga inopfuura nepakati pemwenje bhedhi uye yoenda kune iyo yakaipa electrode yeIC, kuitira kuti kudonha kwemagetsi kumberi kuve kudiki uye kupikisa kunova kudiki. Iyo yakajairika anode drive ndeyekuti ikozvino inoyerera kubva kuPCB board kuenda kune mwenje bead, iyo inopa simba kune chip zvakafanana, uye kudonha kwemagetsi kumberi kwedunhu kunowedzera.
Chechipiri, magetsi emagetsi akasiyana, iyo yakajairwa cathode drive, voltage yeiyo red chip ingangoita 2.8V, uye voltage yeblue uye yegirini machipisi ingangoita 3.8V. Rudzi urwu rwemagetsi emagetsi runogona kuwana kwakaringana magetsi uye mashoma mashandisiro emagetsi, uye kupisa kunogadzirwa neiyo LED kuratidzwa panguva yebasa. Uyewo zvishoma. Common anode drive, pasi pemamiriro ekugara aripo, iyo yakakwira voltage, yakakwira simba, uye yakakura chiyero chekushandisa simba. Panguva imwecheteyo, iyo tsvuku tsvuku inoda mhepo yakaderera kupfuura yebhuruu uye yakasvibirira machipisi, saka zvinodikanwa kuti uwedzere kupikisa kuparadzanisa Pasi pekumanikidzwa, iyo inotungamira kuratidzwa ichaunzawo kupisa kwakanyanya panguva yebasa.
SRYLED tekinoroji - dombo repamusoro rekuvandudzwa kwemicro-pitch LED kuratidza
Zvakanakira zveCOB tekinoroji pachayo zvave zvinotariswa pamusika, uye SRYLED COB yakasimudza tekinoroji yeCOB kusvika pahurefu hutsva. COB pachayo ndeye yakawanda-mwenje yakabatanidzwa bracket-isina kurongedza tekinoroji iyo inovhara zvakananga mwenje-emitting chip paPCB board. Iyo inonetesa yekumusoro yekumisikidza maitiro inosiiwa, uye hapana inotengeswa tsoka yebhuraketi. Iyo LED chip uye solder waya yepixel yega yega yakanyatso uye yakavharirwa mucolloid ne epoxy resin, pasina chero zvinhu zvakafumurwa. Kuti dzidzivirire, inogona kugadzirisa dambudziko rekukuvara kwepixels inokonzerwa nekunze zvinhu. SRYLED COB inogona kuwedzera zvakanyanya kuwanda kwazvino, kuvandudza kugadzikana uye kujeka kwemwenje wemarambi, uye chimiro cheSRYL chinogona kuzadzisa zvinodiwa zvakadaro. , Kuvimbika kwepamusoro, uye zvakanakira zvisiri-zvinopenya zvechiedza chepasi kuti uwedzere kunatsiridza kuvimbika, kurerutsa maitiro ekugadzira, uye kuwana zvirinani zviratidziro, izvo zvinogona kuwana chip-level spacing uye kusvika padanho reMicro LED.
Ndezvipi zvakanakira zvinounzwa neCOB?
COB inoyambuka zvipimo zvepakeji tekinoroji uye inoita kuti kukwirira kuve diki. Tatangisa zvigadzirwa zvine pitch ye0.6mm kuti isangane nezvinodiwa zvepamusoro-tsanangudzo 8K LED kuratidza. Mazuva ano, inonyanya kushandiswa munzvimbo dzakasiyana-siyana dzekuraira, nzvimbo dzedhata, studio nzvimbo, nzvimbo dzemisangano, nzvimbo dzekutengeserana, dzimba dzemitambo, nezvimwe. hungwaru, pamwe nekumhanyisa kukurumidza kwekuvakwa kweruzivo rwenyika uye shanduko yeruzivo rwemaguta, nzvimbo yemusika yekuratidzira icharamba ichikura. , varaidzo midhiya uye minda yekuchengetedza, tarisiro yemusika yakajeka kwazvo. Mune ramangwana, zvigadzirwa zvekuratidzira zvicharamba zvichikura kusvika kune madiki madiki.
