Nekuenderera mberi kwekuvandudza uye kuvandudzwa kweiyo LED tekinoroji, akawanda uye akawanda ekunze ekushambadzira masikirini ari kuchinja kubva kuhombe kuenda kudiki, uye kubva kudiki kuenda kuchena. Muindasitiri yekuratidzira ye LED, yekunze yakakwira-tsanangudzo yekunze advertising skrini zvigadzirwa zvakaiswa pamusoro. Kunze kwepamusoro-yakamisikidzwa ma LED anoratidza anoshandisa emhando yepamusoro mwenje-emitting machipisi sechinhu chepakati, uye emhando yepamusoro mutyairi ICs akazara-ruvara LED kuratidza. Yakakwira density, kona yekuona, kugadzikana, kufanana kweruvara, kuzara kwemavara, kunaka kwemapendero emifananidzo, yakatsetseka vhidhiyo mhedzisiro, nezvimwe zvakapa kutamba kwakazara kune ekupedzisira mabhenefiti ekunze anotungamira advertising skrini.Shenzhen Xinyiguanginoshandisa marambi mabhero sechinhu chepakati kuti aongorore akati wandei-akaiswa pamusoro-akaiswa marambi mabhero ayo anowanzoshandiswa panze pamusika.
▲ Kunze kwepamusoro gomo glue yekuzadza maitiro dhizaini
Yekutanga bhedhi remwenje ndeye SMD2828, uye mamodheru aanogona kushandisa mune inotungamira kuratidzwa ndeayagomo rekunze rekunze P5, P6, P6.25nemamwe mamodheru ekunze. Zvigadzirwa zvekunze hazvingogumiri kune aya matatu mamodheru. Kunewo zvekunze zvekurojesa skrini P6.67 uye pasi tile skrini P7.8125 uye P8.928, izvo zvinomiririra zvigadzirwa zvekunze kunyorera uye danho rekushandisa. Saizi yekutaridzika kweSMD2828 ndeye 3.0 × 3.0 × 2.4mm, uye yakakosha isina mvura chimiro dhizaini inovandudza hunyoro-inoshanda basa. Muchirongwa chekuzadza glue isina mvura, yakakosha silica gel yemapepa ekunze ekunze inoshandiswa. Ukobvu hweglue ndeye 1.5mm, iyo inonyatso kuparadzanisa mvura inonaya kubva pakubvisa PCB board, kudzivirira zvinhu zvakashata senge mapfupi maseketi.
Rudzi rwechipiri ndiSMD3535. Saizi ye3535 rambi bead yakakura kupfuura iyo ye2828, uye saizi yekutaridzika i3.5 × 3.5 × 2.8mm mukukora. Zvinowanzo shandiswa zvekunze zviratidziro zvinosanganisira yekunze-yakaiswa P8 yakazara-ruvara kuratidza uye yekunze P10 yakazara-ruvara kuratidza. Nekuda kwezvimedu zvakakura zvemwenje, iko kushandiswa kwekunze kwepamusoro-tsanangudzo kudiki pane ye2828. Iyo 3535 inotora dhizaini yemuchena mukati uye dema kunze, iyo inovandudza zvakanyanya kusiyanisa. Iyo isina mvura glue yekuzadza maitiro inoshandisa yakakosha silicone kune ekunze zvimata, uye ukobvu hweglue i1.5mm.

Kunze kwepamusoro-yakamisikidzwa P8led kuratidza uye P10led kuratidzwa ine chinhambwe chakakura pakati pavo. Uchishandisa 3535 mwenje marambi uye yakakwirira-tsoka mwenje mabhero, yakajairika glue yekuzadza muchina unogona kugadzirisa dambudziko. Zvisineyi, P5, P6, uye P6.25 vane hunyanzvi hwepamusoro zvinodiwa mukuita. Kana iwe ukasagona tekinoroji yekuzadza glue zvakanaka, zvinokanganisa kutaridzika uye kuenderana kwese skrini. Shenzhen Xinyiguang yakaita basa rakawanda mune izvi, kugadzirisa zvachose dambudziko rekudzima skrini rinokonzerwa nekunze kwepamusoro gomo rekuzadza glue.
